Reduction in baroreflex cardiovascular responses due to venous infusion in the rabbit. (1/3107)

We studied reflex bradycardia and depression of mean arterial blood pressure (MAP) during left aortic nerve (LAN) stimulation before and after volume infusion in the anesthetized rabbit. Step increases in mean right atrial pressure (MRAP) to 10 mm Hg did not result in a significant change in heart rate or MAP. After volume loading, responses to LAN stimulation were not as great and the degree of attenuation was propoetional to the level of increased MRAP. A change in responsiveness was observed after elevation of MRAP by only 1 mm Hg, corresponding to less than a 10% increase in average calculated blood volume. after an increase in MRAP of 10 mm Hg, peak responses were attenuated by 44% (heart rate) and 52% (MAP), and the initial slopes (rate of change) were reduced by 46% (heart rate) and 66% (MAP). Comparison of the responses after infusion with blood and dextran solutions indicated that hemodilution was an unlikely explanation for the attenuation of the reflex responses. Total arterial baroreceptor denervation (ABD) abolished the volume-related attenuation was still present following bilateral aortic nerve section or vagotomy. It thus appears that the carotid sinus responds to changes inblood volume and influences the reflex cardiovascular responses to afferent stimulation of the LAN. On the other hand, cardiopulmonary receptors subserved by vagal afferents do not appear to be involved.  (+info)

Of them, 34 (37%) had an abnormal alanine-aminotransferase (ALT) baseline pattern, and the other 12 (13%) showed ALT flare-ups during the follow-up. TTV DNA in patient sera collected at the time of enrollment and at the end of follow-up was determined by polymerase chain reaction (PCR). In parallel, serum samples from 100 healthy blood donors were also tested. At baseline, 87 patient sera (93.5%) tested positive for the TTV DNA. Of these TTV DNA-positive patients, 84 (96.5%) remained viremic at the end of the study period. Of the 6 TTV DNA-negative patients, 3 acquired TTV infection during follow-up. However, no definite relation was observed between the results of TTV DNA determination and ALT patterns. TTV viremia was also detectable in 22% of blood donors. In conclusion, TTV infection is frequent and persistent among Italian transfusion-dependent patients. The high rate of viremia observed in healthy donors indicates that the parenteral route is not the only mode of TTV spread.  (+info)

Soluble HLA class I, HLA class II, and Fas ligand in blood components: a possible key to explain the immunomodulatory effects of allogeneic blood transfusions. (3/3107)

The immunomodulatory effect of allogeneic blood transfusions (ABT) has been known for many years. However, a complete understanding of the effects of ABT on the recipient's immune system has remained elusive. Soluble HLA class I (sHLA-I), HLA class II (sHLA-II), and Fas ligand (sFasL) molecules may play immunoregulatory roles. We determined by double-determinant immunoenzymatic assay (DDIA) sHLA-I, sHLA-II, and sFasL concentrations in different blood components. sHLA-I and sFasL levels in red blood cells (RBCs) stored for up to 30 days and in random-donor platelets are significantly (P <.001) higher than in other blood components and their amount is proportionate to the number of residual donor leukocytes and to the length of storage. Blood components with high sHLA-I and sFasL levels play immunoregulatory roles in vitro as in allogeneic mixed lymphocyte responses (MLR) and antigen-specific cytotoxic T-cell (CTL) activity, and induce apoptosis in Fas-positive cells. These data suggest that soluble molecules in blood components are functional. If these results are paralleled in vivo, they should be taken into account in transfusion practice. Blood components that can cause immunosuppression should be chosen to induce transplantation tolerance, whereas blood components that lack immunosuppressive effects should be preferred to reduce the risk of postoperative complications and cancer recurrence.  (+info)

Structural and functional consequences of antigenic modulation of red blood cells with methoxypoly(ethylene glycol). (4/3107)

We previously showed that the covalent modification of the red blood cell (RBC) surface with methoxypoly(ethylene glycol) [mPEG; MW approximately 5 kD] could significantly attenuate the immunologic recognition of surface antigens. However, to make these antigenically silent RBC a clinically viable option, the mPEG-modified RBC must maintain normal cellular structure and functions. To this end, mPEG-derivatization was found to have no significant detrimental effects on RBC structure or function at concentrations that effectively blocked antigenic recognition of a variety of RBC antigens. Importantly, RBC lysis, morphology, and hemoglobin oxidation state were unaffected by mPEG-modification. Furthermore, as shown by functional studies of Band 3, a major site of modification, PEG-binding does not affect protein function, as evidenced by normal SO4- flux. Similarly, Na+ and K+ homeostasis were unaffected. The functional aspects of the mPEG-modified RBC were also maintained, as evidenced by normal oxygen binding and cellular deformability. Perhaps most importantly, mPEG-derivatized mouse RBC showed normal in vivo survival ( approximately 50 days) with no sensitization after repeated transfusions. These data further support the hypothesis that the covalent attachment of nonimmunogenic materials (eg, mPEG) to intact RBC may have significant application in transfusion medicine, especially for the chronically transfused and/or allosensitized patient.  (+info)

Endoscopic retreatment compared with surgery in patients with recurrent bleeding after initial endoscopic control of bleeding ulcers. (5/3107)

BACKGROUND AND METHODS: After endoscopic treatment to control bleeding of peptic ulcers, bleeding recurs in 15 to 20 percent of patients. In a prospective, randomized study, we compared endoscopic retreatment with surgery after initial endoscopy. Over a 40-month period, 1169 of 3473 adults who were admitted to our hospital with bleeding peptic ulcers underwent endoscopy to reestablish hemostasis. Of 100 patients with recurrent bleeding, 7 patients with cancer and 1 patient with cardiac arrest were excluded from the study; 48 patients were randomly assigned to undergo immediate endoscopic retreatment and 44 were assigned to undergo surgery. The type of operation used was left to the surgeon. Bleeding was considered to have recurred in the event of any one of the following: vomiting of fresh blood, hypotension and melena, or a requirement for more than four units of blood in the 72-hour period after endoscopic treatment. RESULTS: Of the 48 patients who were assigned to endoscopic retreatment, 35 had long-term control of bleeding. Thirteen underwent salvage surgery, 11 because retreatment failed and 2 because of perforations resulting from thermocoagulation. Five patients in the endoscopy group died within 30 days, as compared with eight patients in the surgery group (P=0.37). Seven patients in the endoscopy group (including 6 who underwent salvage surgery) had complications, as compared with 16 in the surgery group (P=0.03). The duration of hospitalization, the need for hospitalization in the intensive care unit and the resultant duration of that stay, and the number of blood transfusions were similar in the two groups. In multivariate analysis, hypotension at randomization (P=0.01) and an ulcer size of at least 2 cm (P=0.03) were independent factors predictive of the failure of endoscopic retreatment. CONCLUSIONS: In patients with peptic ulcers and recurrent bleeding after initial endoscopic control of bleeding, endoscopic retreatment reduces the need for surgery without increasing the risk of death and is associated with fewer complications than is surgery.  (+info)

Primary percutaneous transluminal coronary angioplasty performed for acute myocardial infarction in a patient with idiopathic thrombocytopenic purpura. (6/3107)

A 72-year-old female with idiopathic thrombocytopenic purpura (ITP) complained of severe chest pain. Electrocardiography showed ST-segment depression and negative T wave in I, aVL and V4-6. Following a diagnosis of acute myocardial infarction (AMI), urgent coronary angiography revealed 99% organic stenosis with delayed flow in the proximal segment and 50% in the middle segment of the left anterior descending artery (LAD). Subsequently, percutaneous transluminal coronary angioplasty (PTCA) for the stenosis in the proximal LAD was performed. In the coronary care unit, her blood pressure dropped. Hematomas around the puncture sites were observed and the platelet count was 28,000/mm3. After transfusion, electrocardiography revealed ST-segment elevation in I, aVL and V1-6. Urgent recatheterization disclosed total occlusion in the middle segment of the LAD. Subsequently, PTCA was performed successfully. Then, intravenous immunoglobulin increased the platelet count and the bleeding tendency disappeared. A case of AMI with ITP is rare. The present case suggests that primary PTCA can be a useful therapeutic strategy, but careful attention must be paid to hemostasis and to managing the platelet count.  (+info)

Hormonal changes in thalassaemia major. (7/3107)

Patients with severe thalassaemia major suffer endocrine and other abnormalities before their eventual death from iron overload due to repeated blood transfusions. The endocrine status of 31 thalassaemic patients aged 2-5 to 23 years was investigated. Exact data were available on the rate and duration of blood transfusion in all of them and in many the liver iron concentration was also known. Although the patients were euthyroid, the mean serum thyroxine level was significantly lower, and the mean thyrotrophic hormone level significantly higher, compared with the values found in normal children. Forty oral glucose tolerance tests with simultaneous insulin levels were performed in 19 children, of whom 5 developed symptomatic diabetes and one had impaired tolerance. Previous tests on all 6 patients were available and some showed raised insulin levels possibly due to insulin resistance. 2 patients had clinical hypoparathyroidism and are described. The parathyroid hormone levels determined by radioimmunoassay in 25 patients were below the mean for the age group in all and outside the reference range in 16. Nonfasting plasma calcium levels were not reduced. Puberty was delayed in some patients. Concentrations of luteinizing hormone (LH) and follicle-stimulating hormone (FSH) measured in urine from 7 girls and 5 boys showed considerable variation. In the boys there was an overall tendency for FSH and LH excretion to be low with regard to age, but with respect to puberty rating FSH exretions were normal or low and LH normal or raised. The girls showed a tendency for LH but not FSH excretion to be raised in relation to puberty rating. The severity of the endocrine changes was related to the degree of iron loading and is discussed in relation to previous work in which the iron loading has rarely been accurately indicated nor parathyroid status assessed.  (+info)

Prospective randomized multicenter study comparing cyclosporin alone versus the combination of antithymocyte globulin and cyclosporin for treatment of patients with nonsevere aplastic anemia: a report from the European Blood and Marrow Transplant (EBMT) Severe Aplastic Anaemia Working Party. (8/3107)

We report the results of the first prospective randomized multicenter study of immunosuppressive treatment in patients with previously untreated nonsevere aplastic anemia (AA) as defined by a neutrophil count of at least 0.5 x 10(9)/L and transfusion dependence. Patients were randomized to receive cyclosporin (CSA) alone or the combination of horse antithymocyte globulin ([ATG] Lymphoglobuline; Merieux, Lyon, France) and CSA. The endpoint of the study was the hematologic response at 6 months. One hundred fifteen patients were randomized and assessable with a median follow-up period of 36 months; 61 received CSA and 54 ATG and CSA. In the CSA group, the percentage of complete and partial responders was 23% and 23%, respectively, for an overall response rate of 46%. A significantly higher overall response rate of 74% was found in the ATG and CSA group, with 57% complete and 17% partial responders (P =. 02). Compared with CSA alone, the combination of ATG and CSA resulted in a significantly higher median hemoglobin level and platelet count at 6 months. Fewer patients required a second course of treatment before 6 months due to a nonresponse. In the CSA group, 15 of 61 (25%) patients required a course of ATG before 6 months because of disease progression, compared with only 3 of 54 (6%) in the ATG and CSA group. The survival probabilities for the two groups were comparable, 93% (CSA group) and 91% (ATG and CSA group), but at 180 days, the prevalence of patients surviving free of transfusions, which excluded patients requiring second treatment because of nonresponse, death, disease progression, or relapse, was 67% in the CSA group and 90% in the ATG and CSA group (P =.001). We conclude that the combination of ATG and CSA is superior to CSA alone in terms of the hematologic response, the quality of response, and early mortality, and a second course of immunosuppression is less frequently required.  (+info)

However, cancer occurrence in transfusion recipients remains poorly characterized. METHODS: We used computerized files from Scandinavian blood banks to identify a cohort of 888,843 cancer-free recipients transfused after 1968. The recipients were followed from first registered transfusion until the date of death, emigration, cancer diagnosis, or December 31, 2002, whichever came first. Relative risks were expressed as ratios of the ...
It turned out that Jai, who was a Thalassemic patient since he was just a year old, had contracted HIV through blood transfusion at the Junagadh Civil Hospital. And it wasnt just him; 35 other Thalassemic children being given transfusion at the same hospital had become HIV-infected. Of them, eight died.. All our happiness died with our child. Who do we live for now? said 50-year-old Rafeeq Ranava, Jais father, a daily-wage labourer in Junagadh.. An IndiaSpend investigation, through a series of Right to Information (RTI) requests, has revealed that 14,474 cases of HIV through blood transfusion have been reported in India over the last seven years. It also revealed that the Indian government has yet to order a study or inquiry into this medical crisis that puts millions of lives at risk.. Not just that, there has been a 10 per cent rise in the number of such cases over the last one year - from 1,424 in 2014-15 to 1,559 in 2015-16 - according to documents obtained from that National AIDS ...

Monthly blood transfusions may lower the chances of silent strokes in some children with sickle cell anemia, a new clinical trial indicates.. The study, reported in the Aug. 21 issue of the New England Journal of Medicine, found that in children with a previous silent stroke, monthly blood transfusions cut the rate of future strokes by more than half.. The researchers said their findings support screening children with sickle cell for evidence of silent stroke - something that is not routinely done now.. Prior to this, there was no treatment, so the argument was, Why screen? explained Dr. James Casella, vice chair of the clinical trial and director of pediatric hematology at Johns Hopkins Childrens Center in Baltimore. Now we have a treatment to offer.. However, Casella also stressed that this study is a first step, not the last one.. Many questions remain, he said. A big one is, do the blood transfusions have to be continued for life?. Its possible the treatment could be ...

Blood transfusion is administered during many types of surgery, but its efficacy and safety are increasingly questioned. Evaluation of the efficacy of agents, such as desmopressin (DDAVP; 1-deamino-8-D-arginine-vasopressin), that may reduce perioperative blood loss is needed.To examine the evidence for the efficacy of DDAVP in reducing perioperative blood loss and the need for red cell transfusion in people who do not have inherited bleeding disorders.We searched for randomised controlled trials (RCTs) in the Cochrane Central Register of Controlled Trials (2017, issue 3) in the Cochrane Library, MEDLINE (from 1946), Embase (from 1974), the Cumulative Index to Nursing and Allied Health Literature (CINAHL) (from 1937), the Transfusion Evidence Library (from 1980), and ongoing trial databases (all searches to 3 April 2017).We included randomised controlled trials comparing DDAVP to placebo or an active comparator (e.g. tranexamic acid, aprotinin) before, during, or immediately after surgery or after

HIV infection through blood transfusions is very rare in the US because all donated blood is carefully screened. Please select the best answer from the choices provided. T F
Not really no. Most blood transfusions we think about are red blood cells or platelets, which dont have the immune function youre asking for. Thats a good thing. Usually, if there are white blood cells in the transfused blood, the hosts immune system will recognize them as foreign and destroy them. Remember, your cells all look like foreign invaders to my cells; blood transfusions of red blood cells are carefully matched to limit negative reactions. There is also a process called transfusion-associated graft versus host disease in which the donor white blood cells will attack the host cells; this mainly occurs in immune-compromised individuals, but GvHD is definitely something to avoid. Blood transfusions are usually filtered and irradiated to remove, among other things, white blood cells.. That being said, people are beginning to use white blood cells as treatment. A new therapy being studied heavily for all sorts of diseases, from cancer to HIV, is to take the hosts own white blood cells ...
Transfusion of washed intra-operative cell salvage post-operatively in the PCICU can be performed safely without increased risk of bleeding or release of inflammatory mediators. This will reduce the need for allogeneic blood products as well as crystalloid and colloid infusions and thus decrease the length of ventilation and intensive care duration for these infants ...
by Vetscite. Blood transfusions are one of the most common procedures patients receive in the hospital but the more red blood cells they receive, the greater their risk of infection, says a new study led by the University of Michigan Heath System and VA Ann Arbor Healthcare System. Researchers analyzed 21 randomized controlled trials for the study that appears in Journal of the American Medical Association (JAMA). Elderly patients undergoing hip or knee surgeries were most susceptible, with a 30 percent lower risk of infection when fewer transfusions were used. Overall, for every 38 hospitalized patients considered for a red blood cell transfusion (RBC), one patient would be spared a serious infection if fewer transfusions were used. Transfusions are often used for anemia or during surgery to make up for blood loss. The authors evaluated all health care-associated infections that were reported after receiving donor blood in the randomized trials. These included serious infections such as ...
As French physicians frequently and currently deployed in Theater of Operations in Africa, we read with interest the article by Ariyo et al.1 reviewing the anesthesia care provided at Médecins Sans Frontières facilities between 2008 and 2014. Spinal anesthesia was the most common type of anesthetic technique (34,413 [45.56%]), with cesarean section being the most common type of procedure performed (26,091 [34.54%]). Wound surgeries represented another common procedure type included in this retrospective study (18,547 [24.55%]). In this context, perioperative deaths occurred in 72 (0.21%) cases of obstetrics/gynecology and urology surgery and in only seven (0.06%) cases of wound surgeries. Nevertheless, the authors did not provide any details regarding the causes of death or any details about the incidence of perioperative bleeding and perioperative blood management. Perioperative blood management refers to perioperative blood transfusion and adjuvant therapies.2 Perioperative blood transfusion ...

Background: Despite the minimally invasive nature of trans-catheter aortic valve implantation (TAVI), the procedure is associated with several complications. We analyzed the individual impact of bleeding events, hemoglobin (Hb) drop, and Red Blood Cells (RBC) transfusions on prognosis.. Methods and results: Consecutive patients (n=597) undergoing trans-femoral TAVI were prospectively enrolled. Peri-procedural Hb levels, RBC transfusions and major/life threatening bleeding events were documented and analyzed. To study the relationship between Hb drop, RBC transfusions and long-term mortality, the entire cohort was divided into 4 groups according to Hb drop (less or ≥ than 3 g/dl), and receiving RBC transfusion (yes /no). In the entire cohort mean Hb level decreased following TAVI (11.8±1.4 to 9.5 ±1.3 g/dl; p,0.001). Major/ life threatening bleedings occurred in 66 (10.1%) patients, and 179 (30%) patients received RBC transfusions. Major/life threatening bleedings were not independently ...
BACKGROUND: The purpose of the study was to investigate allogeneic blood transfusion (ABT) and preoperative anemia as risk factors for surgical site infection (SSI). STUDY DESIGN AND METHODS: A prospective, observational cohort of 5873 consecutive general surgical procedures at Basel University Hospital was analyzed to determine the relationship between perioperative ABT and preoperative anemia and the incidence of SSI. ABT was defined as transfusion of leukoreduced red blood cells during surgery and anemia as hemoglobin concentration of less than 120 g/L before surgery. Surgical wounds and resulting infections were assessed to Centers for Disease Control standards. RESULTS: The overall SSI rate was 4.8% (284 of 5873). In univariable logistic regression analyses, perioperative ABT (crude odds ratio [OR], 2.93; 95% confidence interval [CI], 2.1 to 4.0; p , 0.001) and preoperative anemia (crude OR, 1.32; 95% CI, 1.0 to 1.7; p = 0.037) were significantly associated with an increased odds of SSI. ...
We measured antibody (anti-HCV) to hepatitis C virus, which causes non-A, non-B hepatitis, by radioimmunoassay in prospectively followed transfusion recipients and their donors. Of 15 patients with chronic non-A, non-B hepatitis documented by liver biopsy, all seroconverted for the antibody; of 5 with acute resolving non-A, non-B hepatitis, 3 (60 percent) seroconverted. The development of anti-HCV was delayed (mean delay, 21.9 weeks after transfusion, or 15 weeks after the onset of clinical hepatitis) and took approximately one year in one patient. Antibody has persisted in 14 of the 15 patients with chronic disease (mean follow-up, greater than or equal to 6.9 years; maximum, greater than or equal to 12), but has disappeared in the 3 with acute resolving disease after a mean of 4.1 years. Anti-HCV was detected in samples of donor serum given to 14 (88 percent) of the 16 anti-HCV-positive patients for whom all donor samples were available. Only 33 percent of the anti-HCV-positive donors tested ...

Conclusions There is a lack of current guidelines outlining when to give terminally ill cancer patients a blood transfusion, due to the fact that every patient needs to be individually assessed. Generally, attitudes towards blood transfusions were positive; most thought that suffering was an appropriate reason for a blood transfusion. The large majority did not think that blood transfusions should be withheld. Attitudes towards blood transfusions with palliative intent were slightly more positive in oncology compared to palliative care healthcare professionals.. ...
BACKGROUND: Open simple prostatectomy has long been associated with large blood losses; hence allogeneic blood transfusion in this procedure is a standard practice world over. A review of literature suggests significant association between perioperative blood loss accompanying open simple prostatectomy and certain patient factors. The shortage of blood and blood products in our blood transfusion centres as well as the alarming risks of transfusion reactions and disease dissemination demanded a review of these factors with the aim of reducing morbidity associated with peri-operative blood loss and blood transfusion. OBJECTIVES: To assess blood loss, determine blood transfusion rate, and define some of the factors associated with peri-operative blood loss and blood transfusion in open simple prostatectomy. DESIGN : A prospective cohort study. SETTINGS: The urology units of Kenyatta National Hospital, Kenya. RESULTS: Ninety five patients who underwent open simple prostatectomy for benign prostatic ...
Some time ago my delightful 80+ year-old grandmother was diagnosed with a GI bleed that led to hospitalization and multiple transfusions. As I am the only nurse in the family, she made a point to tell me that she needed blood because her hemoglobins were low.. I quickly determined that she had no idea what hemoglobin was but she was confident her transfusion therapy was necessary because her trusted family physician had told her that her hemoglobins were low. During her admission, she signed without reading a general treatment consent that included a paragraph about blood transfusion. My grandmother was not told that there are risks associated with allogeneic transfusion nor was any alternative therapy offered. However, she believed that she was receiving appropriate medical care and she had no apparent adverse events with her hospitalization. Was my grandmother given adequate information to make an informed choice about her medical care? Did her physician and hospital meet minimum legal and ...

AU - Clifford, Leanne. AU - Kor, Daryl J. AU - Pathak, Jyotishman. PY - 2015/11/4. Y1 - 2015/11/4. N2 - Of the 21 million blood components transfused in the United States during 2011, approximately 1 in 414 resulted in complication [1]. Two complications in particular, transfusion-related acute lung injury (TRALI) and transfusion-associated circulatory overload (TACO), are especially concerning. These two alone accounted for 62% of reported transfusion-related fatalities in 2013 [2]. We have previously developed a set of machine learning base models for predicting the likelihood of these adverse reactions, with a goal towards better informing the clinician prior to a transfusion decision. Here we describe recent work incorporating ensemble learning approaches to predicting TACO/TRALI. In particular we describe ...
Most physicians typically clamp and cut the umbilical cord immediately following delivery. Some physicians advocate for delaying the clamping of the babys umbilical cord, thereby increasing the flow of blood from the placenta to the child. The practice of delayed umbilical cord clamping has been shown to improve hematocrit levels, leading to an increased number of oxygen-carrying red blood cells throughout the body.. Hematocrit levels are an important factor during surgery and blood transfusions are often required to replace blood lost during complicated procedures. This is especially true in children with critical congenital heart disease.. Babies born with critical congenital heart disease often require multiple blood transfusions during corrective heart surgery due to the complexity of the surgery and the babies small size, said Carl Backes, Jr., MD, Neonatology fellow at Nationwide Childrens Hospital. However, data suggests that surgical outcomes are improved when fewer blood ...
Wheat grass juice reduces transfusion requirements in patients with thalassemia major: a pilot study.. Marwaha, R., Bansal, D., Kaur, S., Trehan A. 2004. Indian Ped. 41:716-720. Patients with thalassemia consuming wheat grass juice on a daily basis reduced on average their requirements for blood transfusion. Families raised and prepared the wheat grass at home and a comparison was made with the requirements of the patient in the preceding year. In nearly all patients the mean interval between visits increased and the blood transfused decreased during the wheat grass period. The mechanism involved is unknown.. ...
Published: 18 Jan 2017 , Last Updated: 18 Jan 2017 08:49:11 Karen Humm (Lecturer in Emergency and Critical Care) has been awarded a grant by Pet Plan for the following project: Is Cross Matching Beneficial Prior to the First Blood Transfusion in Cats? As veterinary practice has advanced, there has been a steady increase in the need for blood transfusions to help cats with a variety of diseases. However, identifying suitable blood donors and obtaining blood from healthy cats in a timely manner is extremely challenging. In situations when a cat has had a previous blood transfusion, it is recommended that prior to any subsequent transfusion a crossmatch screening test is performed. This is how we check that donor blood and patient blood are compatible. If no reaction is seen in this test, the donor is considered suitable and this should decrease the risk of the recipient having a reaction to the blood. A recent study of cats reported that administration of crossmatch compatible blood transfusions ...

BACKGROUND: In sub-Saharan Africa, the prevalence of malaria parasitemia in blood donors varies from 0.6% to 50%. Although the burden of TTM in malaria-endemic countries is unknown, it is recommended that all donated blood is screened for malaria parasites. This study aimed to establish the incidence of TTM and identify a suitable screening test. METHODS: Pregnant women, children, and immunocompromised malaria-negative transfusion recipients in a teaching hospital in Ghana were recruited over the course of 1 year. Parasites detected in recipients within 14 days of the transfusion were genotyped and compared to parasites in the transfused blood.

Per hospital policy, when a blood transfusion is ordered, two registered nurses are supposed to perform a two-tiered check to ensure the right blood is going to the right patient. Before the blood enters the room, two nurses must make sure the patients information lines up with the blood product. If everything matches, the nurses are supposed to then go to the patients bedside and perform additional checks to verify the identity of the patient.. However, some nurses have testified in the hearing that its common practice that everything is checked and signed off on at the nurses station and then the primary nurse goes into the patients room to verify identity and administer the blood transfusion.. During the hearing, nurses including and in addition to the two nurses fired, have said it is common practice to check the blood for the transfusion at the nurses desk. However, Karen Ames, director of quality and patient safety at Cayuga Medical Center, testified Monday that she found no evidence ...
Objective: To evaluate semen parameters and measure serum follicle-stimulating hormone (FSH), luteinizing hormone (LH), and testosterone (T) concentrations before and 7 days after packed red cell transfusion (PCTx) in adults with sickle cell disease (SCD). Methods: This prospective study investigated 18 young adults with transfusion-dependent SCD, aged 20.7 +/- 2.88 years, with full pubertal development (Tanner's stage 5) (euogonadal), and capacity to ejaculate. Their serum ferritin levels were 1488 +/- 557ng/ml. Basal serum concentrations of FSH, LH, T and IGF-I were evaluated before and 7 days after packed red cell transfusion (PCTx). We studied the effect of PCTx on semen parameters and the endocrine functions in these 18 patients with SCD. Results: Following PCTx, a significant increase of Hb from 8.5 +/- 1.17 g/dl to 10.5 +/- 0.4 g/dl was associated with increased testosterone (12.3 +/- 1.24 nmol/L to 14.23 +/- 1.22nmol/L and gonadotropin concentrations.

Abstract:. BACKGROUND AND OBJECTIVE: This audit was conducted as a part of a quality assurance activity to assess the frequency of receiving completely filled out blood transfusion reaction forms which were accompanied by the required samples. Once this information is known, we will elevate the bar each year to achieve 100% compliance. The sub-aim was to evaluate the frequency of the reported transfusion reactions.. MATERIALS AND METHODS: The study was conducted from 1st April 2010 to 30th April 2011. The information was evaluated and the frequency of receiving completely filled blood transfusion reaction forms was assessed. The variables identified were the type of transfusion reaction, the blood component transfused, the health care personnel filling the form, and whether there was legible handwriting and a completely filled form. Transfusion reactions were reported as a percentage of the total number of units transfused.. RESULTS: During the study period, 17,880 packed red cells, 13,200 ...
This program will review the creation and benefits of Blood School, an eight-hour introductory course on transfusion safety for nurses. Recognizing that primary blood transfusion education was too procedure-centric, this course was developed as a supplement to provide education on the core foundations of transfusion medicine. Blood School uses a combination of didactic and active learning approaches, in order for the participants to feel more knowledgeable, comfortable, and safer with all transfusion-related processes. In doing so, it empowers them to be better advocates for patients, take action whenever they recognize negative situations related to blood transfusions, and help ensure that the right patient gets the right blood component for the right reason in the safest way. ...

There have been previous studies with similar hypotheses and methodology. Engoren et al. 12 studied 1,915 subjects undergoing first-time isolated coronary artery bypass at St. Vincent Mercy Medical Center, Toledo, Ohio. In a Cox regression model, they demonstrated that age, New York Heart Association functional class IV, chronic obstructive pulmonary disease, peripheral vascular disease, and perioperative blood transfusion were predictors of mortality occurring between 1 and 5 yr after surgery. Detailed information about the number of units transfused was not available; therefore, quantification of transfusion was done in a limited manner, subjects were grouped according to transfusions given during the intraoperative period, postoperative period, or both. Koch et al. 13 studied 10,289 subjects undergoing isolated coronary artery surgery at the Cleveland Clinic, follow-up was 10 yr, and transfusion was quantified by the number of units of red cells transfused to subjects in the perioperative ...

Substantial variability in practice exists in clinical transfusion, patient blood management and blood conservation in paediatrics. Neonates and children are frequently transfused patient populations, yet they are relatively under-represented in clinical trials and the evidence-base to guide practice is limited. A number of clinical practices are extrapolated from the results of adult studies. Yet neonates and children have unique pathophysiology, specific vulnerabilities and different risk profiles compared to adult transfusion recipients. A disproportionate number of transfusion adverse events are reported in the neonatal and paediatric age groups. Any adverse outcome related to transfusion is particularly important in these young recipients, as most are anticipated to live for many years post transfusion. Transfusion decision making in paediatrics needs to consider the potential risks and benefits of a transfusion and any alternatives to transfusion. ...

I have anemia and needed a blood transfusion and attempted my first transfusion last week. After about a tablespoon of blood went into my IV, my vision grayed out and I dont remember what happened next. I was told I had chills, diaphoresis, decreased level of consciousness, eyes rolling back in head and woke up so to speak, vomiting. What happened to me? They said I had no fever but had a severe transfusion reaction. I received Benadryl and Solu-Medrol and a bag of fluid after that. They had stopped the blood when I came to and said my blood pressure had dropped to 70/40 and my pulse had dropped. My family doctor was called and diagnosed it as a vasovagal reaction. Can a severe blood transfusion reaction be called a vasovagal reaction? They said there was no hemolyzation of the blood. What exactly happened? How often does this happen? They gave me another unit with the premedication and filter, and it seemed to work okay that time. What do I need to understand about what happened ...
In one of the largest randomized controlled trials (RCTs) on GDT, the incidence of blood transfusions was double (22 vs 11%) in the GDT group patients, who received nearly twice the amount of colloids compared to the control group, even though the same transfusion threshold (Hb , 8 g/dl) was used for both groups [11]. The most feasible explanation for this clinically relevant and statistically significant difference (p = 0.04 based on a chi square test), which was not calculated nor discussed in the article [11], is that more patients in the GDT group reached Hb levels below the transfusion threshold due to hemodilution, prompting physicians to order blood transfusions. Other RCTs have also reported that patients in the GDT group, who received significantly more colloid boluses, received significantly more blood transfusions [12, 13] and had significantly higher blood loss [13] compared to the standard therapy group. In another study, the administration of more colloids led to lower Hb and DO2 ...

Transfusion-Related Acute Lung Injury (TRALI) is an important life-threatening complication that is related with blood transfusion. The frequency is reported as 1/5.000. It is generally characterized with hypoxia that appears at the 2-6th hours after the blood transfusion, bilateral infiltration in the chest radiography, and non-cardiogenic pulmonary edema. Acute respiratory distress, hypotension, tachycardia and fever accompany the clinical picture. Past surgery, blood transfusion, and sepsis are among the factors that trigger the disease. In this study, the efficiency of the hemodialysis applied in the right time in the treatment of a heavy TRALI case developed after a blood transfusion has been presented..

Abstract:. BACKGROUND: Intraosseous (IO) vascular access is increasingly used as an emergency tool for achieving access to the systemic circulation in critically ill patients. The role of IO transfusion of blood in Damage Control Resuscitation is however questionable due to possible inadequate flow rate and hemolysis. Some experts claim that IO transfusion is contraindicated. In this study we have challenged this statement by looking at flow rates of autologous fresh whole blood reinfusion and hemolysis using two of the commonly used FDA-approved and CE-marked sternal needles. Additionally, the success rate of sternal access between the two devices is evaluated.. METHODS: Volunteer professional military personnel, were enrolled prospectively in an non-randomized observational study design. We collected 450 ml of autologous whole blood from each participant. Participants were divided into the following three groups of 10: T.A.L.O.N. IO, FAST1 IO, and intravenous (IV) group. The reinfusion was ...

A panel of eight different primary antibodies and two different phycoerythrin-conjugated secondary antibodies was used for the detection of different blood populations. The flow cytometer used in this study was the BD FACSArray® instrument. Mixed red blood cell populations were prepared from phenotype known donors. Linearity, specificity, recovery, precision, robustness and interday-precision were tested for every primary antibody used in the presented assay. The technique of signal amplification was utilized for an improved separation of antigens with weak or heterozygous expression to improve the interpretation of histograms. The resulting method allowed to clearly ...
A delayed hemolytic transfusion reaction (DHTR) is a type of transfusion reaction. It is defined as fever and other symptoms/ signs of hemolysis more than 24 hours after transfusion; confirmed by one or more of the following: a fall in haemoglobin (Hb) level or failure of Hb level to rise after transfusion rise in bilirubin (jaundice) incompatible crossmatch not detectable pre-transfusion. This can occur up to four weeks after the transfusion. Delayed blood transfusion reaction occurs more frequently (1 in 20,569 blood components transfused in the USA in 2011) when compared to acute haemolytic transfusion reaction. One way this can occur is if a person without a Kidd blood antigen receives a Kidd antigen in a transfusion. Other common blood groups with this reaction are Duffy and Kell.

Many people diagnosed with haematological malignancies experience anaemia, and red blood cell (RBC) transfusion plays an essential supportive role in their management. Different strategies have been developed for RBC transfusions. A restrictive transfusion strategy seeks to maintain a lower haemoglobin level (usually between 70 g/L to 90 g/L) with a trigger for transfusion when the haemoglobin drops below 70 g/L), whereas a liberal transfusion strategy aims to maintain a higher haemoglobin (usually between 100 g/L to 120 g/L, with a threshold for transfusion when haemoglobin drops below 100 g/L). In people undergoing surgery or who have been admitted to intensive care a restrictive transfusion strategy has been shown to be safe and in some cases safer than a liberal transfusion strategy. However, it is not known whether it is safe in people with haematological malignancies.To determine the efficacy and safety of restrictive versus liberal RBC transfusion strategies for people diagnosed with

Children undergoing cardiac surgery with cardiopulmonary bypass (CPB) are at high risk of being exposed to relatively large volumes of allogeneic blood products. If blood transfusion can be life-saving in some circumstances (e.g. major haemodilution or massive haemorrhage), the administration of large volumes of allogeneic blood products has been shown to significantly increase the risk of postoperative complications. Over the last decades, different strategies have been developed to reduce the need for blood product transfusions.. Acute normovolemic hemodilution (ANH) has been used for a long time in adults undergoing high bleeding risk procedures, including cardiac surgery. While some studies reported a decrease in the incidence of transfusion and in the volume of red blood cells transfused, only limited evidence exists in infants and children undergoing cardiac surgery. Major differences exist between children and adults undergoing cardiac surgery, limiting the use of ANH to a small number of ...
There are two common forms of treatment:. Steroid therapy: Approximately 70% of people diagnosed with DBA have steroid therapy which improves their anaemia. However, in some cases steroid therapy can stop working and the anaemia may return. Sometimes steroid therapy is used in combination with cyclosporin A. Those who respond to steroid treatment may remain on steroids for the rest of their lives.. Blood transfusions: For those who do not respond to steroid treatment, regular blood transfusions may be required. It is important to note that recipients of regular blood transfusions may be at risk of iron overload*. Iron overload occurs when there is a buildup of iron in the body as a result of blood transfusions. It is important to discuss this with your health care professional.. ...

Despite having many studies to evaluate the role of TXA in surgeries, limited literature is available on its role in hip fracture surgeries. In an RCT, TXA was administered as an initial bolus dose of 500mg before surgery followed by continuous infusion at 1mg/kg/h for the duration of surgery. Results showed that the differences in mean reduction in Hb and mean volume of blood loss postoperatively between TXA and placebo groups were significant. In addition, only 7 out of 45 patients in TXA group required blood transfusion compared to 18 out of 45 in placebo group and the difference was again significant.5 On the contrary, another RCT in 2010 concluded that there was no significant difference in blood transfusion rates between TXA and placebo groups after surgery for hip fracture.3 Therefore, although effectiveness of TXA in reducing post-surgical blood loss and transfusion requirements have been shown by multiple studies, but its effectiveness, specifically in hip fracture surgeries, is yet to ...

Transfusion threshold adherence will be described as the proportion of per protocol RBC transfusion events. A transfusion threshold event is defined as an occurrence which starts when a haemoglobin value is measured at or below the allocated threshold for the first time since the previous event and ends when one of the following occurs: (1) an RBC transfusion is administered; or (2) a repeat haemoglobin is obtained above the allocated threshold within 24 hours of the original measure.. Transfusion threshold non-adherence will be considered to have occurred with any of the following: (1) an RBC transfusion occurs before a transfusion threshold is crossed; or (2) in the liberal arm, a transfusion is not given following a threshold crossing. Transfusion threshold non-adherence will be considered a deviation if: (1) the early transfusion occurs within 5 g/L above the allocated threshold (eg, ≤105 g/L for the liberal arm or ≤85 g/L for the restrictive arm) or, (2) in the liberal arm, an RBC ...
Indications for red blood transfusion depend on clinical assessment and the cause of the anemia. In a stable, non-bleeding patient, often a single unit of blood is adequate to relieve patient symptoms or to raise the hemoglobin to an acceptable level. Transfusions are associated with increased morbidity and mortality in high-risk hospitalized inpatients. Transfusion decisions should be influenced by symptoms and hemoglobin concentration. Single unit red cell transfusions should be the standard for non-bleeding, hospitalized patients. Additional units should only be prescribed after re-assessment of the patient and their hemoglobin value.. Sources:. Bracey AW, et al.

Preoperative autologous donation is the process of collecting and storing a patients own blood prior to an elective procedure where it is anticipated that the patient will most likely require a blood transfusion. A patients suitability for preoperative autologous donation is based on their ability to tolerate several venesections (blood donations) taken over a short period of time, their age, adequate venous access (to enable blood to be taken) and reliable dates for elective surgery.. Preoperative autologous donation can deplete the bodys iron stores and iron is very important to ensure your blood can carry enough oxygen. Even though it is your blood, risks still exist with autologous blood, including bacterial contamination, clerical error and the increased chance of receiving a blood transfusion. Whilst it is commonly perceived that autologous transfusion removes the risk of transfusion-transmissible infection, the overall safety of autologous blood transfusion is not significantly ...
Why this is important:- Audits have shown that fresh frozen plasma is widely used for non-bleeding patients in the intensive care unit (ICU) and many other clinical settings. There is a large variation in dose and no real evidence base to guide practice.

PURPOSE: This study tested the hypothesis that autologous blood transfusion (ABT) of ~50% of the red blood cells (RBC) from a standard 450-mL phlebotomy would increase mean power in a cycling time trial. In addition, the study investigated whether further ABT of RBC obtained from another 450-mL phlebotomy would increase repeated cycling sprint ability.. METHODS: In a randomized, double-blind, placebo-controlled crossover design (3-month wash-out), nine highly trained male subjects donated two 450-mL blood bags each (BT trial) or were sham phlebotomized (PLA trial). Four weeks later, a 650-kcal time trial (n = 7) was performed 3 d before and 2 h after receiving either ~50% (135 mL) of the RBC or a sham transfusion. On the following day, transfusion of RBC (235 mL) from the second donation or sham transfusion was completed. A 4 × 30-s all-out cycling sprint interspersed by 4 min of recovery was performed 6 d before and 3 d after the second ABT (n = 9).. RESULTS: The mean power was increased in ...
Acute reduction in hemoglobin levels is frequently seen during sepsis. Previous studies have focused on the management of anemia in patients with septic shock admitted to intensive care units (ICUs), including aggressive blood transfusion aiming to enhance tissue oxygenation. To study the changes in hemoglobin concentrations during the first week of sepsis in the setting of Internal Medicine (IM) units, and their correlation to survival. Observational prospective study. We recorded hemoglobin values upon admission and throughout the first week of hospital stay in a consecutive cohort of septic patients admitted to IM units at a community hospital, the patients were enrolled into a prospective registry. Data on blood transfusions was also collected, we examined the correlation between hemoglobin concentrations during the first week of sepsis and survival, the effect of blood transfusion was also assessed. Eight hundred and fifteen patients (815) with sepsis were enrolled between February 2008 to January

Transfusion-related acute lung injury (TRALI) is the leading cause of transfusion-associated mortality in the US. Previously, we established an immune-mediated TRALI mouse model, wherein mice with cognate antigen were challenged with MHC class I mAb. In this study, when mice housed in a rodent, specific pathogen-free barrier room were challenged with MHC I mAb, there was significant protection from TRALI compared with nonbarrier mice. Priming mice with LPS restored lung injury with mAb challenge. Using TLR4-deficient bone marrow chimeras, the priming phenotype was restricted to animals with WT hematopoietic cells, and depletion of either neutrophils or platelets was protective. Both neutrophils and platelets were sequestered in the lungs of mice with TRALI, and retention of platelets was neutrophil dependent. Interestingly, treatment with aspirin prevented lung injury and mortality, but blocking the P selectin or CD11b/CD18 pathways did not. These data suggest a 2-step mechanism of TRALI: ...
Introduction:. HLA specific antibodies detection (HSA) and that of Donor Specific Antibodies (DSA) were revolutionized by the introduction of solid phase assays (Luminex®), therefore making these antibodies a powerful biomarker for humoral injuries to the allograft. Determinants of HSA development entail non-adherence to immunosuppressive drugs but also allosensitizing events such as red blood cell (RBC) transfusions. Recent works showed a higher incidence of DSA in transplanted patients following RBC transfusion events, but no specific data exist for AntiThymocyte Globulin (ATG) induction.. This work aims at assessing whether peri-transplant RBC transfusion resulted in post-transplant HLA sensitization, in the setting of ATG induction therapy.. Patients and methods:. All consecutive patients benefiting from a first ATG-induced kidney allograft between 2004 and 2014 at our center with no history of HLA immunization were included retrospectively, provided transfusion history and HSA history were ...

Negative side effects of blood transfusion therapy are uncommon. Blood banks, hospitals, and health-care providers take many precautions to minimize risks before each blood transfusion. Blood banks test each unit of blood to find out its ABO type and Rh status.

It begins with the basics of genetics and immunology, and then progresses to the technical aspects of blood banking and transfusion. Chapters are divided into sections on: Basic Science Review; Blood Group Serology; Donation, Preparation, and Storage; Pretransfusion Testing; Transfusion Therapy; Clinical Considerations; and Safety, Quality Assurance, and Data Management. Developed specifically for medical technologists, blood bank specialists, and residents, the new edition conforms to the most current standards of the American Association of Blood Banks (AABB).
Transfusion-associated graft-versus-host disease (TA-GvHD) is a rare complication of blood transfusion, in which the donor T lymphocytes mount an immune response against the recipients lymphoid tissue. Donor lymphocytes are usually identified as foreign and destroyed by the recipients immune system. However, in situations where the recipient is immunocompromised (inborn immunodeficiency, acquired immunodeficiency, malignancy), or when the donor is homozygous and the recipient is heterozygous for an HLA haplotype (as can occur in directed donations from first-degree relatives), the recipients immune system is not able to destroy the donor lymphocytes. This can result in graft-versus-host disease. The incidence of TA-GvHD in immunocompromised patients receiving blood transfusions is estimated to be 0.1 - 1.0%, and mortality around 80 - 90%. Mortality is higher in TA-GvHD than in GvHD associated with bone marrow transplantation, where the engrafted lymphoid cells in the bone marrow are of donor ...
In the past few years there has been increasing concern about blood transfusion safety. Avoidable transfusion errors, mostly in patient identification, remain a serious cause of injury and death. There is also heightened awareness of the risk of transmission of viral and bacterial infections. Of particular concern in Britain is the (theoretical) possibility of transmission of variant Creutzfeldt-Jakob disease.. This review puts these risks in perspective (table) and describes the new measures that have been introduced to improve blood safety. It also describes changes in attitude and practice that will affect users of blood in all disciplines, including general practitioners advising patients of the pros and cons of transfusion. Finally it emphasises the need for careful education and training of all those involved in blood prescribing and blood component administration. ...

  • This publication focuses on specific areas, which are essential to any effective blood transfusion service: organization and management, blood donor motivation and blood collection, and the assurance of quality. (
  • Blood from a donor needs to match the blood type of the person receiving it. (
  • After blood typing is complete, a compatible donor blood is chosen. (
  • As a final check, a blood bank technologist will mix a small sample of your child's blood with a small sample of the donor blood to confirm they are compatible. (
  • The death from vCJD of an individual in the UK who had previously received a blood transfusion from a donor who went on to have vCJD was announced on December 17, 2003. (
  • Robert Will from the National CJD Surveillance Unit, Edinburgh, UK and colleagues outline the process which links individuals from the UK CJD register with data from the national blood-donor database to identify the number of blood donors who went on to develop vCJD and to compare vCJD incidence between donors and recipients. (
  • One of these recipients (the case whose death was reported last December) developed symptoms of vCJD 6.5 years after receiving a transfusion of red cells donated by an individual 3.5 years before the donor developed symptoms of vCJD. (
  • What donor and donation factors need to be considered to maintain an adequate supply of blood during the pandemic? (
  • Diminished donor inflow, lack of staff personnel, shortage of blood units, and concerns about transfusion-transmitted COVID-19 among people were some of the major challenges faced by blood banks and hospitals during the crisis. (
  • Also, few donor centers experienced a dramatic reduction in blood donations due to the implementation of lockdown and the cancellation of blood drives. (
  • Without this technology, you would require about two plus pints of blood from an anonymous donor. (
  • According to a news release from the U.K.'s National Health Service, scientists created the lab-grown red blood cells from donor stem cells. (
  • So, even though you screened donor units for the hepatitis B virus to eliminate tainted blood, people were still getting hepatitis from blood transfusions. (
  • We conclude that alloimmunization is a common, clinically serious problem in sickle cell anemia and that it is partly due to racial differences between the blood-donor and recipient populations. (
  • This system is called Individual Donor Risk Assessment and is similar to the system that was introduced in the UK Blood Services in 2021. (
  • In twin-to-twin transfusion syndrome (TTTS), the communication of placental vessels between the donor and recipient twin creates an imbalance of blood flow resulting in anemia in the donor and polycythemia in the recipient. (
  • The communication of placental vessels between the donor and recipient twin creates an imbalance of blood flow resulting in anemia in the donor and polycythemia in the recipient. (
  • Through arteriovenous anastomosis, the blood flows from the donor to the recipient. (
  • If laser ablation is delayed, the continuous process of blood flowing unidirectionally makes the donor anemic. (
  • To get a blood transfusion safely, a person's immune system must recognize the donor cells as a match to his or her own cells. (
  • Health Canada, the country's regulatory authority, announced this week that it has "authorized a submission from Héma-Québec to implement a more inclusive approach to blood donor screening. (
  • In Kenya blood donor selection criteria were reviewed in 2009. (
  • Regular review of effectiveness of donor selection criteria can help reduce TTIs prevalence amongst donors and thus make the blood supply safer. (
  • Evidence that donor leukocytes in transfused blood can be detected by PCR of the recipient blood suggests that this minor population of donor white cells (microchimerism) can interfere with genotyping of allelic polymorphisms in critically ill transfused patients. (
  • Blood transfusion-associated infections are rarer now than in the past due to improved blood donor screening. (
  • For blood, these questions can be asked directly of the donor, while for organs and tissues, the donor is most commonly deceased, so the history is obtained from next of kin or a very close friend. (
  • On 14 June 2020 WHO and all countries worldwide will celebrate World Blood Donor Day! (
  • This is invaluable information for our organization, and for other blood operators in the process of evaluating blood testing and donor eligibility criteria. (
  • Dr. Fearon's expertise is particularly valuable to the National Testing Lab, the Donor Testing Labs and the Canadian Blood Services' Medical Directors. (
  • A recipient who is immunocompetent may mount an immune response to the donor antigens (i.e., alloimmunization), resulting in various clinical consequences, depending on the blood cells and specific antigens involved. (
  • Leukocyte reduction of transfused blood products virtually eliminates donor APCs, but patients may still develop alloimmunization. (
  • A small number of West Nile virus infections have been reported from blood transfusions. (
  • These automated platforms have been pivotal in the rapid detection of Transfusion Transmissible Infections (TTI's) in blood samples and can precisely eliminate human error during the transfusion process. (
  • Because of this, and the potential risk of side effects from blood transfusions (reactions or infections), the WHO recommend conservative transfusion strategies. (
  • According to the Mayo Clinic , blood transfusions can cause a number of health complications, including allergic reactions, fevers, lung injury, spread of bloodborne infections and acute immune hemolytic reaction - a rare transfusion reaction in which a person's body attacks the new blood because it's not the proper type. (
  • unsafe transfusion practices can put millions of people at risk of Transfusion Transmissible Infections (TTIs). (
  • It's been estimated that about one in 200, or half of one percent of organ transplants, possibly transmit unexpected infections, and this rate is likely much lower in blood and tissue. (
  • these infections were spread through transfusion and transplantation. (
  • Mike Miller] What has already been done to prevent transfusion and transplant transmitted infections? (
  • What infections are particularly challenging to prevent, and what does a new infection in transfusion or transplant recipients mean for the rest of us, the general public? (
  • Monitoring trends in known infections, identifying new infectious diseases and developing appropriate policies are critical in maintaining a safe blood system. (
  • Led by Dr. Fearon, Dr. Mindy Goldman and Dr. Sheila O'Brien, Canadian Blood Services carries out comprehensive surveillance of bloodborne pathogens to monitor changing trends in known infections, identify new infectious diseases and develop policies appropriately. (
  • O'Brien SF, Dines IR, Goldman M, Scalia V, Yi Q, Fan W, Fearon M. Impact of testing the blood supply for Human T Lymphotropic Virus (HTLV) on recipient infections. (
  • Since 2004, PEPFAR has provided ongoing financial and technical support to more than 14 countries with NBTS programs, with the goal of ensuring an adequate supply of safe blood from voluntary non-remunerated donors through screening for transfusion-transmissible infections, such as HIV, syphilis, Hepatitis B, and Hepatitis C. (
  • PEPFAR, through CDC, also supports infrastructure and laboratory development, technical assistance and training, universal testing of blood units for HIV with other transfusion-transmissible infections, development of safe injection policies, and expansion of safe disposal among healthcare workers and community members. (
  • Donation centers try to ensure that donors who recently had West Nile virus do not give blood for 120 days. (
  • This risk may be higher during the summer when West Nile virus is most likely to infect blood donors. (
  • Unlike blood donors, not all organ donors are tested for West Nile virus. (
  • There's no medical proof that blood from directed donors is any safer than blood from volunteer donors. (
  • Amongst those who attended the ceremony were members of the Diplomatic corps, the civil society, religious leaders, NGOs, Blood donors' associations, partners and stakeholders in the Safe blood transfusion domain. (
  • Blood banks collect blood from volunteer donors. (
  • This is why blood banks are always looking for donors. (
  • 48 individuals were identified as having received a blood component from 15 donors who later became vCJD cases. (
  • COVID-19 has had major implications for patients who need blood transfusions, blood donors, and the transfusion services and hospitals that manage transfusions. (
  • We wanted to see what kind of practical guidance was out there, in terms of changes that have been made in other countries to keep donors, volunteers and staff as safe as possible at blood collections sites, and the possible actions that can be taken to ensure blood availability. (
  • It is a crucial part of transfusion therapy, which provides critical information to healthcare professionals and confirms the compatibility of donors and recipient blood samples. (
  • Findings seen for red blood cells from female, previously pregnant, or sex-discordant donors. (
  • We assessed the effect that racial differences might have on the frequency of alloimmunization by comparing the red-cell phenotypes of patients and blood-bank donors (n = 200, 90 percent white). (
  • Comparison of red-cell phenotypes in the three study groups (the patients with sickle cell anemia, the patients with other forms of anemia, and the blood donors) revealed statistically significant differences between the patients with sickle cell anemia and the donors but not between the patients with other forms of anemia and the donors. (
  • Avoiding transfusions from family members is important because of possible sensitization against non-HLA (human leukocyte antigen) tissue antigens of potential donors. (
  • So there's always a need for blood donors. (
  • About 15% of blood donors are high school and college students. (
  • a cross sectional study was conducted between November 2011 to January 2012 among 594 blood donors in the Regional Blood Transfusion Center Nakuru and Tenwek Mission Hospital . (
  • Blood donors who were married (P=0.0057), had non-formal or just primary education (P=0.0262), had multiple sexual partners (P=0.0144) and in informal occupation (P=0.0176) were at higher risk of HIV positivity. (
  • Since organs are in such short supply compared with the thousands of people on the transplant waiting list, screening for infectious diseases in organ donors is not as restrictive as for blood and tissue donors. (
  • Better screening of donors has reduced the risk of transmitting HIV, hepatitis B, and hepatitis C. However, there will always be a risk of infectious diseases being transmitted from donated blood, organs, and tissues - no matter what screening or testing is done - because pathogens can evade testing, and sometimes testing can't be done because laboratory methods have not been developed yet for the pathogen. (
  • Though the number of blood donors increased by 11 per cent last year, the increase was not enough to meet the increasing demand for blood," she said. (
  • With the objective of meeting the demand for blood, the Blood Donors' Association (BLODAN) has launched an e-blood banking scheme. (
  • We launched new programmes to increase the number of blood donors," said Mahendra Bilash Joshi, president of BLODAN. (
  • Canadian Blood Services also researches the prevalence rates of certain viruses in Canadian donors to inform policy development. (
  • Dr. Fearon is involved in seroprevalence studies on the emerging pathogens Babesia microti and Hepatitis E. She is currently collaborating with Hema Quebec and the American Red Cross to set up the largest North American HEV prevalence study ever performed in blood donors. (

  • In Rwanda, the NBTS instituted a cross-cutting incentive system to attract and retain voluntary blood donors with repeat donors qualifying for items such as insecticide-treated bed nets to combat malaria. (
  • Platelets , the smallest blood cells, help blood to clot and control bleeding. (
  • Blood loss may result from injury, major surgery, or diseases that destroy red blood cells or platelets , two important blood components. (
  • If you have lost a great deal of blood, or if your clotting factors or platelets are low or abnormal, you may also need a transfusion of either of these to help control bleeding. (
  • It is made up of several main components, including red blood cells, white blood cells, platelets, and plasma. (
  • Platelets help the blood form clots, which stops bleeding. (
  • So some people getting treatment for cancer might need a transfusion of red blood cells or platelets. (
  • To determine the effectiveness and safety of transfusing patients with severe trauma and major bleeding using plasma, platelets, and red blood cells in a 1:1:1 ratio compared with a 1:1:2 ratio. (
  • The Irish Blood Transfusion Service provides life-saving platelets to all of the hospitals in Ireland. (
  • One group in particular has become well-known for this reason: Jehovah's Witnesses refuse transfusions of whole blood, of red and white corpuscles, platelets and plasma since 1945, when the legal organisation of leaders of the Congregation of Jehovah's Witnesses, the Watch Tower Bible and Tract Society concluded that it was against divine law. (
  • Transfusions of packed red blood cells (RBCs) and platelets are administered on an outpatient basis. (
  • It's composed of both liquids (plasma) made of protein, salt, and water, and solids made of platelets, white blood cells, and red blood cells. (
  • Bloodless cardiac surgery is a safe alternative for patients who have serious heart conditions but cannot or choose not to receive any blood or blood products (red cells, white cells, plasma or platelets). (
  • Can I donate blood if I was diagnosed with West Nile virus infection? (
  • If you recently had a transfusion, you should be aware of the very small risk for West Nile virus infection. (
  • White blood cells help the body fight infection. (
  • Two studies in this week's issue of THE LANCET highlight the public-health implications of blood transfusion as a possible route for infection by the prion protein responsible for variant Creutzfeldt-Jakob disease (vCJD). (
  • Robert Will comments: "Our findings raise the possibility that this infection was transfusion transmitted. (
  • However, the age of the patient was well beyond that of most vCJD cases, and the chance of observing a case of vCJD in a recipient in the absence of transfusion transmitted infection is about 1 in 15 000 to 1 in 30 000. (
  • Features of SARS-CoV-2 infection that affect patients' needs for transfusion. (
  • Each blood unit must be tested for blood group typing and disease screening in order to prevent adverse reactions or transmission of any infection. (
  • White blood cells are part of your immune system and help fight infection. (
  • Blood cells are suspended in a watery, yellowish liquid called plasma, which also contains proteins partly responsible for blood clotting and globulins that help fight infection and disease. (
  • The technology not only reduces blood loss, infection, and the volume of ischemic tissue, its simplicity saves as much as fifteen minutes of critical OR set-up time‚ eliminating over 100 separate steps that can add as much as $300 to every procedure. (
  • [ 3 ] A complete blood count (CBC) count with differential may be helpful for determining the severity of infection. (
  • If using blood-bank support, attempt to minimize the risk of cytomegalovirus (CMV) infection. (
  • In 1971, hepatitis B surface antigen testing heralded the advent of screening to minimize infection transmission complicating allogeneic transfusion. (
  • Inexperience in reading smears or a low index of suspicion for the infection may also result in false-negative blood smear results. (
  • For blood and tissues, the screening is more stringent, and any risk for infection found, either through behavior history or laboratory testing, results in the donation being declined. (
  • The major complications, which account for almost 75% of al maternal deaths, are severe haemorrhage, infection, high blood pressure during pregnancy (pre-eclampsia and eclampsia), complications during childbirth and unsafe abortion. (
  • Blood Transfusion in Severe Dengue Infection This case series suggests that in many cases of severe dengue infection refractory to standard treatment, blood transfusion may produce rapid improvement, even in patients without bleeding. (
  • If you have many blood transfusions, you are more likely to have problems from immune system reactions. (
  • Acetaminophen and diphenhydramine premedication for for allergic and febrile nonhemolytic transfusion reactions may be ineffective and unsafe. (
  • Of the 32 alloimmunized patients with sickle cell anemia, 17 had multiple antibodies and 14 had delayed transfusion reactions. (
  • These problems were compounded by a short-staffed nursing crew that lacked training in how to detect adverse reactions during transfusions and a hospital laboratory with too few workers on staff to always catch potentially fatal labeling mistakes, according to the government report. (
  • Although perioperative autologous blood transfusions are associated with few side effects, transfusion reactions can occur and can be life-threatening. (
  • Autologous transfusions can trigger febrile nonhemolytic transfusion reactions, which may result in airway compromise. (

  • In this article, Jerry Bergman examines the Jehovah's Witnesses position against the use of blood transfusions. (
  • The religious community of Jehovah's Witnesses of Moscow were dissolved for various reasons, one of which was the 'No Blood' card's existence, as Russian courts decided that participation in the activities of the community had been damaging for the health of its followers because they had refused blood transfusions. (
  • A reaction causes your body to form antibodies that attack the new blood cells. (
  • But building immune cells or antibodies for the fight takes a few good months and the first baby is safe," said Kanchan Mukherjee, who performed the transfusions. (
  • These antibodies attack the positive red blood cells (RCB) in the baby during the second pregnancy. (
  • Transfusion therapy for sickle cell anemia is limited by the development of antibodies to foreign red cells. (
  • Depending on which blood type you have, your immune system will make antibodies to react against other blood types. (
  • If a patient gets the wrong blood type, the antibodies immediately set out to destroy the invading cells. (
  • Because your blood contains the A marker, it makes B antibodies. (
  • Your body will have both A and B antibodies and will therefore feel the need to defend itself against A, B, and AB blood. (
  • Refractoriness to granulocyte transfusion involves either HLA or granulocyte-specific antibodies and is similar to platelet refractoriness, except that refractoriness to granulocyte transfusion results in the patient failing to respond clinically to the infused granulocytes. (
  • Through the U.S. Centers for Disease Control (CDC), PEPFAR works with Ministries of Health in foreign countries to develop and strengthen national blood transfusion services (NBTS), with a particular focus on countries with a high burden of HIV. (
  • Hospitals use them to help people who are injured, having surgery, getting cancer treatments, or being treated for other diseases that affect the blood, like sickle cell anemia. (
  • They're at risk for problems from a blood or bleeding disorder, such as sickle cell disease , thalassemia, or anemia caused by kidney disease, hemophilia , or von Willebrand disease . (
  • Fetal blood sampling (FBS) shows that the fetus has severe anemia. (
  • An illness that destroys blood cells, such as hemolytic anemia or thrombocytopenia . (
  • If you have an illness in which your bone marrow doesn't make enough blood, such as aplastic anemia , you may need transfusions. (
  • Also, the increasing number of patients suffering from anemia, which requires red blood cell transfusion for its treatment, is anticipated to upsurge the demand for blood transfusion diagnostics. (
  • But for those with sickle cell anemia and other blood disorders that require frequent transfusions, it could provide more time between treatments. (
  • To evaluate the frequency and risk factors associated with such alloimmunization, we determined the transfusion history, red-cell phenotype, and development of alloantibodies in 107 black patients with sickle cell anemia who received transfusions. (
  • We compared the results with those from similar studies in 51 black patients with sickle cell disease who had not received transfusions and in 19 nonblack patients who received transfusions for other forms of chronic anemia. (
  • Although they received transfusions less frequently, 30 percent of the patients with sickle cell anemia became alloimmunized, in contrast to 5 percent of the comparison-group patients with other forms of anemia (P less than 0.001). (
  • Blood transfusions are standard of care in managing anemia despite sparse evidence that they improve clinical outcomes. (
  • Transfusion is typically ordered because of the risk of anemia - which the National Institutes of Health defines as a condition where the body does not have enough red blood cells. (
  • Frequent outpatient follow-up for patients with aplastic anemia is needed to monitor blood counts and any adverse effects of various drugs. (
  • Patients with aplastic anemia require transfusion support until the diagnosis is established and specific therapy can be instituted. (
  • That leads to too few red blood cells, a condition called anemia . (
  • Anemia describes a diminished circulating red cell mass, expressed as grams of hemoglobin per 100 cc of whole blood. (
  • In malaria endemic areas of sub-Saharan Africa, severe anemia in children due to malaria is estimated to account for at least half of all transfusions while obstetric complications are responsible for up to a quarter. (

  • footnote 1 Transfusion with the wrong blood type can cause a severe reaction that may be life-threatening. (
  • This reduces the risk of disease and transfusion reaction from donated blood. (
  • You may have a mild allergic reaction even if you get the correct blood type. (
  • If you get blood in a transfusion that isn't the right type, you may have a transfusion reaction. (
  • A mild transfusion reaction rarely is dangerous, but you must get treatment quickly. (
  • A severe transfusion reaction can be deadly. (
  • The trial also showed that very few children developed a transfusion reaction or a side effect such as heart failure or lung oedema, indicating that too much volume had been given. (
  • BACKGROUND: Many studies have used polymerase chain reaction amplification (PCR) to genotype for common polymorphisms in intensive-care units (ICUs) where blood transfusions are common. (
  • If your child needs a blood transfusion, the doctor will describe the procedure. (
  • Every 2 seconds, someone needs a blood transfusion. (
  • Losing large amounts of blood quickly can lead to serious complications or death. (
  • Although all types of blood loss may cause complications, it is the large and rapid blood losses that occur during surgery and trauma that are most likely to cause severe complications or death. (
  • The amount of blood loss that may lead to complications depends on the individual person. (
  • The more blood is lost, and the faster it is lost, the more severe the symptoms and complications. (
  • The complications of blood loss are related to the role blood plays in the body (see above). (
  • Complications can be more serious in people taking blood thinners or those with bleeding disorders. (
  • The TRACT trial also showed that children with uncomplicated severe anaemia do not require an immediate transfusion, as long as they are closely monitored for signs of complications, or their haemoglobin levels dropping, and receive a transfusion at that point. (
  • Prespecified ancillary outcomes included time to hemostasis, blood product volumes transfused, complications, incidence of surgical procedures, and functional status. (
  • Likewise, people with blood clots are at a high risk of a pulmonary embolism or deep-vein thrombosis (DVT), and these are also potential complications of which emergency medical personnel need to be made immediately aware. (
  • This testing, along with other required tests, may result in too much blood being drawn from low-weight pediatric patients right before their transplant surgery and may lead to medical complications. (
  • Reduce the risk of medical complications that can happen when too much blood is drawn from a patient at one time. (
  • It focuses on patient education, dietary advice, managing cardiovascular risk, managing blood glucose levels, and identifying and managing long-term complications. (
  • Techniques of "bloodless" surgery, honed for those who refuse transfusions, could help stem what many call an overuse of blood. (
  • The patient's vital signs (temperature, blood pressure, and heart rate) are checked before, during, and after the transfusion. (
  • Two research groups have discovered that nitric oxide disappears rapidly from banked blood -a finding that may explain recent medical studies showing that blood transfusions can sometimes increase a patient's chances of dying from a lack of oxygen. (
  • Four days later, however, hospital staff committed a similar mistake, only this time workers in the lab didn't notice when a blood sample arrived with another patient's blood in it. (
  • [ 5 ] However, it is important that transfusions be guided by the patient's clinical status and not by numbers alone. (
  • In the research setting, the patient's blood can be inoculated into mice and the spirochetes amplified in murine blood. (
  • Physicians have a variety of ways to monitor the effects of chemotherapy on the patient's cancer, including physical examinations, blood tests, CT scans , MRI scans , and x-rays . (
  • Outcomes Using Lower vs. Higher Hemoglobin Thresholds for Red Blood Cell Transfusion" is the inaugural article in JAMA's Clinical Evidence Synopsis section, which will include summaries of large-scale systematic reviews of similar studies. (
  • Strategies to correct or prevent these problems should now be tested with the goal of improving patient outcomes with transfusions, which frequently do more harm than good unless they are restricted,' McMahon said. (
  • 7 g/dL have on clinical outcomes compared to more liberal transfusion triggers? (
  • As more evidence mounts that blood transfusions are associated with worse outcomes, the threshold hemoglobin level for transfusion has decreased. (
  • A second meta-analysis of 16 RCTs found that less restrictive transfusion strategies (triggers of 7.5 to 10 g/dL) were not effective in improving outcomes. (
  • Salpeter SR, Buckley JS, Chatterjee S. Impact of more restrictive blood transfusion strategies on clinical outcomes: a meta-analysis and systematic review. (
  • There is a good evidence to suggest that hypofibrinogenemia in trauma is associated with worse outcomes and it is postulated that early replacement of fibrinogen and red blood cells packages may reduce hemorrhage and improve outcomes even in the pre-hospital phase of care. (
  • For patients in whom hematopoietic cell transplantation (HCT) may be attempted, transfusions should be used judiciously because minimally transfused subjects have achieved superior therapeutic outcomes. (
  • Lack of safe blood directly contributes to poor health outcomes, including high rates of maternal, infant, and under-five mortality. (
  • However, there was strong evidence that the effect of transfusion volume varied by whether the child had a fever at the time of screening (study enrolment), which was at hospital admission in most cases. (
  • In the present study, we investigated the effect of transfusion of stored RBCs on renal IR-induced hepatic injury . (
  • Autologous (ah-TOL-uh-gus) blood donation. (
  • Laryngospasm after autologous blood transfusion. (
  • The laryngospasm could not be attributed to any cause other than the autologous blood transfusion and recurred when the transfusion was restarted. (
  • For instance, according, to the American Red Cross, it was estimated that the organization lost around 46,000 blood unit donations as a result of the pandemic. (
  • The Iranian Blood Transfusion Organization (IBTO) and its most recent activities are hosted on TIF'S website. (
  • A person's risk of blood loss severe enough to require a transfusion during surgery depends on a number of factors, including gender (women generally have a higher risk because they have a smaller volume of blood), health status (conditions such as hemophilia increase the risk of bleeding), and medications or herbs they may be taking (blood thinners such as warfarin* can increase the risk of bleeding). (
  • Around half of children who had no immediate transfusion went on to require a transfusion, mostly because their haemoglobin level fell. (
  • Technology making the transfusion of allogeneic blood products feasible includes Karl Landsteiner's landmark identification of the human blood groups A, B, and O in 1901. (
  • Allogeneic blood transfusion is an essential component of medical care. (
  • All patients were critically ill at the time of blood transfusion, with dramatic stabilization of vital parameters after the transfusions. (
  • Only one patient had detectable bleeding, while five patients had occult blood loss as indicated by dropping hematocrit. (

  • WASHINGTON, July 30, 2021) - Today, Senators Jacky Rosen (D-NV), John Barrasso (R-WY), and Tammy Baldwin (D-WI) introduced a bipartisan bill to increase access to palliative blood transfusions for patients receiving end-of-life care through the Medicare hospice benefit. (
  • The bill seeks to address a serious problem many patients with blood cancers on Medicare currently face by establishing a demonstration program that would provide a separate payment model to promote the provision of palliative blood transfusions in hospice, with the goal of ensuring that patients with blood cancers and other hematologic diseases and conditions receive high-quality end-of-life care. (
  • However, in practice, many patients do not have access to transfusions in hospice. (
  • As hematologists, we have seen our patients with blood cancers have to make the very difficult decision between receiving transfusions, which can improve their quality of life but often require a hospital admittance, and hospice care, which would allow them to spend their end of life in the comfort of their own homes. (
  • Unfortunately, this means that patients with hematologic malignancies who need blood transfusions to control their symptoms are less likely to use hospice services than patients with other cancers. (
  • This new bill is a vital first step in ensuring that blood cancer patients are not forced to choose between blood transfusions and hospice care in their final days and can instead focus on spending time with loved ones. (
  • We look forward to continuing to work closely with Senators Rosen, Barrasso, and Baldwin and other members of Congress to ensure that all our patients with blood disorders get the care they need. (
