Intrauterine management of fetal parvovirus B19 infection. (1/717)

OBJECTIVES: The aim of our study was to determine the outcome of pregnancies after intrauterine management of fetal parvovirus B19 infection. DESIGN: Retrospective study. SUBJECTS: A total of 37 cases of maternofetal parvovirus B19 infection, 35 of which were associated with hydrops fetalis, were referred to our tertiary level center between 1989 and 1996. With regard to fetal hydrops, no apparent cause other than parvovirus B19 infection was found in any patient. METHODS: In all patients, cordocentesis was performed to assess the degree of fetal anemia. When anemia was present, cordocentesis was followed by intrauterine transfusion with packed red cells into the umbilical vein. Further management depended on the degree of fetal anemia and gestational age and included follow-up fetal blood sampling/transfusion as well as ultrasound examinations as deemed appropriate. RESULTS: Packed red cell transfusion was performed in 30 patients with significant fetal anemia (Z-score 1.6-7.8 below the mean for gestational age). The fetal hemoglobin values ranged from 2.1 to 9.6 g/dl. Serum levels of platelets in the transfusion group were 9-228 x 10(9)/l with Z-scores in the range of < 1 to 3.8 below the mean. During treatment and follow-up, there were five intrauterine deaths (13.5%), one neonatal death (2.7%) and 31 live births (83.8%). CONCLUSIONS: Fetal parvovirus infection can lead to marked anemia and hydrops formation. Cordocentesis allows precise assessment of fetal anemia which can then be corrected by intravenous transfusion. Under this regimen, the outcome proved favorable in the majority of fetuses, even those that were severely anemic.  (+info)

Allogeneic stem cell transplantation for agnogenic myeloid metaplasia: a European Group for Blood and Marrow Transplantation, Societe Francaise de Greffe de Moelle, Gruppo Italiano per il Trapianto del Midollo Osseo, and Fred Hutchinson Cancer Research Center Collaborative Study. (2/717)

Agnogenic myeloid metaplasia (AMM) is a chronic myeloproliferative disorder in which patients with poor prognostic features, receiving conventional treatments, have a median survival of less than 3 years. In this retrospective multicenter study, we analyze the results and try to define the indications for allogeneic stem cell transplantation in AMM. From January 1979 to November 1997, 55 patients with a median age of 42 years were transplanted from HLA-matched related (n = 49) or alternative (n = 6) donors for AMM. A multivariate analysis was conducted to identify factors associated with posttransplant outcome. The median posttransplant follow-up was 36 months (range, 6 to 223). The 5-year probability of survival was 47% +/- 8% for the overall group, and 54% +/- 8% for patients receiving an unmanipulated HLA-matched related transplant. The 1-year probability of transplant-related mortality was 27% +/- 6%. Hemoglobin level +info)

Survival of donor leukocyte subpopulations in immunocompetent transfusion recipients: frequent long-term microchimerism in severe trauma patients. (3/717)

We recently reported detection of a transient increase in circulating donor leukocytes (WBCs) in immunocompetent recipients 3 to 5 days posttransfusion (tx) (Blood 85:1207, 1995). We have now characterized survival kinetics of specific donor WBC subsets in additional tx populations. Eight female elective surgery patients (pts) were sampled pre-tx and on days 1, 3, 5, 7, and 14 post-tx. Ten female trauma pts transfused with a total of 4 to 18 U of relatively fresh red blood cells were sampled up to 1.5 years post-tx. WBC subsets from frozen whole blood were isolated using CD4, CD8 (T cell), CD15 (myeloid), and CD19 (B cell) antibody-coated magnetic beads. Donor WBCs were counted by quantitative polymerase chain reaction (PCR) of male-specific sex determining region (SRY) sequences. PCR HLA typing and mixed leukocyte reaction (MLR) between recipient and donor WBCs were performed on two of the trauma tx recipients who had long-term chimerism of donor cells post-tx. In 6 of 8 female surgery pts, circulating CD4(+) male donor cells peaked at day 3 or 5 (0.01 to 1 cell/microL), followed by clearance by day 14. In 7 of 10 female trauma pts, we observed multilineage persistence of male donor WBCs (CD4, CD8, CD15, CD19) for 6 months to 1.5 years post-tx at concentrations of 10 to 100 cells/microL. In 2 trauma recipients studied, MLR showed no, or very low, response to WBC of the single donor implicated as the source of microchimerism by HLA typing. Establishment of long-term multilineage chimerism in trauma recipients is probably caused by engraftment of donor stem cells and mutual tolerance between recipient and donor leukocytes. A better understanding of factors determining clearance versus chimerism of transfused leukocytes is critical to prevention of alloimmunization and transfusion-induced graft-versus-host disease, and, potentially, to induction of tolerance for transplantation.  (+info)

Acute normovolaemic haemodilution vs controlled hypotension for reducing the use of allogeneic blood in patients undergoing radical prostatectomy. (4/717)

Blood loss in patients undergoing radical prostatectomy may be substantial. In a randomized, prospective study, we assessed two methods of reducing the need for allogeneic blood transfusion with regard to efficacy and costs. Sixty patients undergoing retropubic radical prostatectomy were allocated randomly to one of three groups. In group 1 (n = 20), acute normovolaemic haemodilution (ANH) was initiated after induction of anaesthesia; autologous blood 15 ml kg-1 was withdrawn and replaced by colloid solutions (gelatin) to maintain haemodynamic stability. In group 2 (n = 20), controlled hypotension was established using sodium nitroprusside (target mean arterial pressure (MAP) approximately 50 mm Hg). Group 3 (n = 20), without manipulations, served as a control group. Troponin T (TnT), a sensitive marker for myocardial ischaemia, and various coagulation variables were measured in the perioperative period. Packed red blood cells (PRBC) were given when haemoglobin concentration was less than 7 g dl-1. Cost calculations did not include hospital overhead costs or staff costs. In the ANH group, mean 1278 (SD 150) ml of autologous blood were withdrawn. Significantly more volume was infused in the ANH patients (gelatin 2450 (550) ml) than in the two other groups. Coagulation data (platelet count, activated partial thromboplastin time (aPTT), fibrinogen, antithrombin III (AT III), D-dimers) did not differ significantly between the three groups. The hypotension group had significantly lower blood loss (1260 (570) ml), whereas the ANH (1820 (680) ml) and control group (1920 (590) ml) did not differ significantly. Patients in the hypotension group needed significantly less PRBC (total 14 units; 75% of patients did not need PRBC) than the ANH (total 21 units; 55% of patients did not need PRBC) or control patients (total 28 units; 40% of patients did not need PRBC). Total costs were lowest in the hypotension group (41% less than in the control patients) (P < 0.05). We conclude that the use of hypotension during radical prostatectomy resulted in approximately 40% reduction in total transfusion costs. ANH was less effective and more costly than controlled hypotension.  (+info)

Kinetics of peroxidases in guinea pig bone marrow under immunostimulation. (5/717)

Eosinophil peroxidase and myeloperoxidase play an important role in the host defense. Both enzymes are present in bone marrow, synthesized by blood progenitor cells. This research investigated the kinetic properties of peroxidases under immunostimulation in guinea pig bone marrow. Results suggest that there are at least two myeloperoxidase isozymes and at least three eosinophil peroxidase isozymes in guinea pig bone marrow and that some of these isozymes are expressed upon immunostimulation.  (+info)

Serious hazards of transfusion (SHOT) initiative: analysis of the first two annual reports. (6/717)

OBJECTIVE: To receive and collate reports of death or major complications of transfusion of blood or components. DESIGN: Haematologists were invited confidentially to report deaths and major complications after blood transfusion during October 1996 to September 1998. SETTING: Hospitals in United Kingdom and Ireland. SUBJECTS: Patients who died or experienced serious complications, as defined below, associated with transfusion of red cells, platelets, fresh frozen plasma, or cryoprecipitate. MAIN OUTCOME MEASURES: Death, "wrong" blood transfused to patient, acute and delayed transfusion reactions, transfusion related acute lung injury, transfusion associated graft versus host disease, post-transfusion purpura, and infection transmitted by transfusion. Circumstances relating to these cases and relative frequency of complications. RESULTS: Over 24 months, 366 cases were reported, of which 191 (52%) were "wrong blood to patient" episodes. Analysis of these revealed multiple errors of identification, often beginning when blood was collected from the blood bank. There were 22 deaths from all causes, including three from ABO incompatibility. There were 12 infections: four bacterial (one fatal), seven viral, and one fatal case of malaria. During the second 12 months, 164/424 hospitals (39%) submitted a "nil to report" return. CONCLUSIONS: Transfusion is now extremely safe, but vigilance is needed to ensure correct identification of blood and patient. Staff education should include awareness of ABO incompatibility and bacterial contamination as causes of life threatening reactions to blood.  (+info)

Epoetin alpha prevents anaemia and reduces transfusion requirements in patients undergoing primarily platinum-based chemotherapy for small cell lung cancer. (7/717)

Anaemia commonly occurs in cancer patients receiving chemotherapy, often necessitating blood transfusion. This multicentre study was designed to evaluate the efficacy and safety of epoetin alpha in preventing the decline in haemoglobin (Hb) level, and to determine whether the transfusion requirement could be reduced, in patients receiving 4-6 cycles of primarily platinum-based combination cyclic chemotherapy for small cell lung cancer (SCLC). A total of 130 non-anaemic SCLC patients were randomized to receive no additional treatment (n = 44), epoetin alpha 150 IU kg(-1) subcutaneously (s.c.) three times a week (n = 42) or 300 IU kg(-1) s.c. three times a week (n = 44). Reductions in epoetin alpha dosage were made during the study if Hb level increased to >15 g dl(-1). The mean weekly dosage was 335 and 612 IU kg(-1), respectively, in the two active treatment groups. Significantly fewer (P < 0.05) epoetin alpha-treated patients experienced anaemia (Hb < 10 g dl(-1)) during the course of chemotherapy (300 IU kg(-1), 39%; 150 IU kg(-1), 48%; untreated, 66%). This was reflected in the significantly lower number of treated patients transfused [300 IU kg(-1), 20% (P< 0.001); 150 IU kg(-1), 45% (P< 0.05); untreated, 59%]. Epoetin alpha was well-tolerated, and there was no evidence of sustained, clinically significant, hypertension. In summary, epoetin alpha is effective and well-tolerated in maintaining Hb level and reducing transfusion requirement in patients undergoing cyclic chemotherapy for SCLC.  (+info)

Early IL-12 p70, but not p40, production by splenic macrophages correlates with host resistance to blood-stage Plasmodium chabaudi AS malaria. (8/717)

In this study, we compared synthesis of IL-12, a potent Th1-inducing cytokine, by splenic macrophages recovered from resistant C57Bl/6 (B6) mice, which develop predominantly Th1 responses, and susceptible A/J mice that mount primarily Th2 responses during early Plasmodium chabaudi AS infection. Quantitative analysis of IL-12 p40 and p70 release by ELISA revealed significant differences between resistant B6 and susceptible A/J mice in the synthesis of biologically active IL-12 p70, but not p40, by splenic macrophages during early blood-stage P. chabaudi AS infection. Despite up-regulation in p40 and p35 mRNA levels, spontaneous release of p40 in vitro by splenic macrophages was not significantly increased following infection in either mouse strain. In contrast, spontaneous release of p70 by splenic macrophages was increased in cells from B6 mice and levels were significantly higher compared with A/J mice. Furthermore, compared with infected A/J hosts, splenic macrophages recovered from infected B6 mice produced significantly greater quantities of IL-12 p70, but not p40, in vitro, following stimulation with lipopolysaccharide (LPS) or malaria parasite antigen (PRBC). Moreover, we found significant increases in the percentage of macrophages earlier in the spleens of infected B6 mice that could further contribute to differences in total p70 levels in vivo. Taken together, these data suggest that macrophage IL-12 synthesis may contribute to the polarization of Th responses seen in resistant B6 and susceptible A/J mice during acute blood-stage malaria.  (+info)

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
A new randomized multicenter pilot study involving six ICUs in the United Kingdom was recently published in Critical Care Medicine journal.9 The authors in this study compared hemoglobin concentration (Hb), RBC use, and patient outcomes when restrictive or liberal blood transfusion strategies are used to treat anemic (Hb ≤ 90 g/L) critically ill patients of age ≥ 55 years requiring ≥ 4 days of mechanical ventilation in the ICU. One hundred patients were randomized to restrictive transfusion strategy targeting 71-90 g/L (n=51) and to liberal transfusion strategy targeting 91-110 g/L (n=49) for 14 days or the remainder of ICU stay, whichever was longest. ...
Background: Allogeneic red blood cell transfusions (ABT) are common in older hip fracture patients. Recent research supports a restrictive transfusion policy. The aim was to study variation in hemoglobin (Hb) concentration, and clinical outcomes in these patients.. Results: Cross-sectional study with one-year follow-up in an orthogeriatric unit. Data were obtained from a quality register with demographic and medical information collected by an interdisciplinary team. 106 (22 %) of the 491 patients admitted from September 2011 throughout September 2012 (76 % women, mean age 85 years) received ABT. When given ABT, 80 % had Hb ,80 g/l and mean Hb was 78 g/l. Mean Hb, regardless ABT, showed variation from 125 g/l (±16) on admission to 106 g/l (±17), 101 g/l (±16) and 102 g/l (±14) on 1st, 3rd and 5th postoperative day respectively. Patients with per-/subtrochanteric fractures more often received ABT than those with femur neck fractures (p , 0.001), 70 % of the patients receiving ABT had a ...

Y1 - 2002. N2 - Background: Fibrin sealants have become popular in improving perioperative haemostasis and reducing the need for allogeneic red cell transfusion. Methods: A systematic review of randomized controlled trials was conducted to examine the efficacy of fibrin sealants in reducing perioperative blood loss and allogeneic red blood cell transfusion. Studies were identified by computer searches of Medline, Embase, Current Contents, the Cochrane Library, manufacturer websites (to January 2001), and bibliographic searches of published articles. Trials were eligible for inclusion if they involved adult elective surgery and reported quantitative data on blood loss, the proportion of patients exposed to allogeneic red cell transfusion and/or the volume of blood transfused. Results: Twelve trials ...
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.

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 ...
The rationale for perioperative red blood cell (RBC) transfusion is based on the observation that anemia is an independent risk factor for morbidity and mortality after cardiac operations. However, transfusions have been associated with high rates of morbidity and mortality in critically ill patients, and some recent studies have shown worse outcomes, including increased occurrence of renal failure and infection, as well as respiratory, cardiac, and neurological complications, in transfused compared with non transfused patients after cardiac surgery. On the basis of past clinical observations, some authors have suggested that hematocrit should be maintained at around 30% and hemoglobin concentration at 10 g/dL. Recently, however, this hemoglobin threshold has been reconsidered because of recognized risks associated with transfusion and greater appreciation of the importance of individual physiological responses to anemia. In a comparative trial of 428 patients undergoing elective coronary artery ...
BACKGROUND: Adverse transfusion reactions in the neonatal population are poorly understood and defined. The incidence and pattern of adverse effects due to red blood cell (RBC) transfusion are not well known, and there has been no systematic review of published adverse events. RBC transfusions continue to be linked to the development of morbidities unique to neonates, including chronic lung disease, retinopathy of prematurity, intraventricular haemorrhage and necrotising enterocolitis. Uncertainties about the exact nature of risks alongside benefits of RBC transfusion may contribute to evidence of widespread variation in neonatal RBC transfusion practice.Our review aims to describe clinical adverse effects attributed to small-volume (10-20 mL/kg) RBC transfusions and, where possible, their incidence rates in the neonatal population through the systematic identification of all relevant studies. METHODS: A comprehensive search of the following bibliographic databases will be performed: MEDLINE (PubMed
BACKGROUND: Delayed hemolytic transfusion reaction (DHTR) can manifest with hyperhemolysis, a serious complication of red blood cell (RBC) transfusions. This has mostly been described in sickle cell anemia but occasionally in beta-thalassemia. Treatment is challenging; immunosuppressive medication has been reported to be useful by some but not others., CASE REPORT: A 1.5-year-old girl with homozygous beta-thalassemia was put on a regular RBC transfusion program because of anemia with stunted growth and abnormal bone development. After the first transfusion she developed DHTR with hyperhemolysis. Further RBC transfusions could not be avoided. Despite treatment with prednisone, immunoglobulins, rituximab, and azathioprine hemolysis continued. She received an allogeneic bone marrow transplantation after conditioning using cyclophosphamide, treosulfan, melfalan, and ATG. The transplantation was followed by treatment with cyclosporin A, methotrexate, and prednisone. Because of poor engraftment and ...

BACKGROUND:. Red blood cell transfusions are an extremely common medical intervention in both the United States and worldwide; over 14 million units of blood are transfused in the United States. Between 60 and 70 percent of all blood is transfused in the surgical setting. Despite the common use of red blood cell transfusions, the threshold for transfusion has not been adequately evaluated and is very controversial. A decade ago, the standard of care was to administer a peri-operative transfusion whenever the hemoglobin (Hgb) level fell below 10 g/dl (the 10/30 rule). Concerns about the safety of blood, especially with respect to HIV and hepatitis, and the absence of data to support a 10 g/dl threshold led to the current standard of care, which is to administer blood transfusions based on the presence of symptoms, and not a specific Hgb/hematocrit level. However, there have not been any randomized clinical trials done with surgical patients that have tested the efficacy and safety of ...

Background - Red blood cell (RBC) transfusion is independently associated in a dose-dependent manner with increased intensive care unit stay, total hospital length of stay, and hospital-acquired complications. Since little is known of the cost of these transfusion-associated adverse outcomes our aim was to determine the total hospital cost associated with RBC transfusion and to assess any dose-dependent relationship. Study Design and Methods - A retrospective cohort study of all multiday acute care inpatients discharged from a five hospital health service in Western Australia between July 2011 and June 2012 was conducted. Main outcome measures were incidence of RBC transfusion and mean inpatient hospital costs. Results - Of 89,996 multiday, acute care inpatient discharges, 4805 (5.3%) were transfused at least 1 unit of RBCs. After potential confounders were adjusted for, the mean inpatient cost was 1.83 times higher in the transfused group compared with the nontransfused group (95% confidence ...
Most trauma deaths are related to traumatic brain injury (TBI). Although the management of patients has improved, mortality remains unacceptably high, and half of survivors of moderate and severe TBI are left with major functional impairment. Current management guidelines are based on limited evidence and practice is highly variable. Most acutely ill patients with TBI will develop anemia, which may decrease oxygen delivery to a fragile brain. While clinical practice is moving towards transfusing at low hemoglobin (Hb) levels, experts have expressed concerns regarding restrictive strategies, which may adversely affect clinical outcomes in TBI. Our primary objective is to evaluate the effect of red blood cell (RBC) transfusion thresholds on neurological functional outcome. We hypothesize that a liberal transfusion strategy improves outcomes compared to a restrictive strategy.
Case Objectives Understand that the traditional transfusion thresholds of hemoglobin below 10 g/dL and hematocrit below 30% are not supported by the evidence. List the common serious adverse effects of transfusion. Describe the evidence supporting a more restrictive transfusion strategy. State what transfusion threshold should be used in hospitalized patients with and without coronary artery disease. Case & Commentary-Part 1:
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 ...

Anemia is frequent among traumatic brain injured (TBI) patients, and it is associated with an increased risk of poor outcomes. The optimal hemoglobin (Hb) level
The conundrum is what clinical factors should influence the routine titrated transfusion decision. The largest trial evaluating transfusion thresholds used prespecified symptoms (such as chest pain, orthostatic hypotension, or tachycardia unresponsive to fluid resuscitation) (1), which we included in our guideline. Although this approach is based on a randomized trial, these symptoms will not apply to all clinical settings. We agree with the accompanying editorial (2) that other variables (such as fatigue, dyspnea, mechanical ventilation, or the use of low Svo2) are unproven. Unfortunately, there is no evidence to support other important individual patient laboratory and physiologic variables as the basis for transfusion decisions ...

TY - CHAP. T1 - What is the evidence for using hemostatic agents in surgery?. AU - Erstad, Brian L. PY - 2005. Y1 - 2005. N2 - The pharmacological methods used to achieve systemic hemostasis have generated much discussion due to concerns of serious adverse effects (e.g., thromboembolic complications) and costs of therapy in addition to efficacy considerations. There are a limited number of well-controlled trials involving pharmacological hemostasis for spine surgery. In the largest doubleblinded randomized controlled trial to date involving spine surgery, there was a trend toward reduced homologous transfusion in patients receiving aprotinin, but the only statistically significant result (p,0.001) was a reduction in autologous red cell donations. The findings of this trial are important, since the investigators used a number of restrictive transfusion strategies (e.g., autologous donation, low hematocrit trigger for transfusion, blood-salvaging procedures with the exception of no cell saver) ...
Preoperative optimization of medical comorbidities prior to spinal surgery is becoming an increasingly important intervention in decreasing postoperative complications and ensuring a satisfactory postoperative course. The treatment of preoperative anemia is based on guidelines made by the American College of Cardiology (ACC), which recommends packed red blood cell transfusion when hematocrit is less than 21% in patients without cardiovascular disease and 24% in patients with cardiovascular disease. The literature has yet to quantify the risk profile associated with preoperative pRBC transfusion ...
The red blood cell transfusions should not be dictated by a single hemoglobin trigger but instead should be based on the patients risks of developing complications of inadequate oxygenation. Red blood cell transfusion is rarely indicated when the hemoglobin concentration is greater than 10 g/dL and is almost always indicated when it is less than 6 g/dL ...
Blood transfusions have been a central component of protocols for care of severe sepsis and septic shock, ever since the single-center 2001 Rivers trial included them in its interventions. Any benefit (or harm) caused by red cell transfusion independently was unknowable, and so the therapy became standard care as part of the so-called sepsis bundle. The Surviving Sepsis guidelines have generally advised transfusion to a hematocrit of 30% or hemoglobin of 10 g/dL during the first 6 hours of septic shock if hypoperfusion (low central venous oxygenation) is present despite fluids and vasopressors.. However, the inclusion of red cell transfusion in sepsis bundles has been frequently challenged, based on the weak observational evidence for its benefit, compared to robust evidence from randomized trials showing transfusion above a hemoglobin of 7 g/dL is unhelpful generally. This finding has been shown in the critically ill (the TRICC trial), after hip surgery (FOCUS trial) and in non-critically ill ...
Experimenting with new format today. About 5 take home points for each lecture. Burns (visiting professor) Transfusion Safety. 1. In general, Less is More when you are considering transfusions. U.S. physicians transfuse more blood products than European and Canadian physicians due to individual practice variation being greater in the U.S. Recent studies have shown that increasing # of units transfused of any blood product correlates directly with increased mortality, length of stay and wound complications even when controlled for patients severity of illness.. 2. Patient outcomes are better with a transfusion threshold of HGB=7 rather than 8 or 10 unless a patient is having ACS. Harwood comment: Is 8 really better than 7 for ACS? Dr. Burns: Yes there is data that the mortality is less for ACS at a transfusion trigger of HGB=8 rather than 7. When you do transfuse, only transfuse a single unit and then re-assess before deciding to give a second unit.. 3. Transfusion trigger for normotensive upper ...
Definitions:. Strength of Recommendations. Strong (grade 1): Strong recommendations (grade 1) are made when there is confidence that the benefits do or do not outweigh harm and burden. Grade 1 recommendations can be applied uniformly to most patients. Regard as recommend.. Weak (grade 2): Where the magnitude of benefit or not is less certain a weaker grade 2 recommendation is made. Grade 2 recommendations require judicious application to individual patients. Regard as suggest.. Quality of Evidence. (A) High: Further research is very unlikely to change confidence in the estimate of effect. Current evidence derived from randomised clinical trials without important limitations.. (B) Moderate: Further research may well have an important impact on confidence in the estimate of effect and may change the estimate. Current evidence derived from randomised clinical trials with important limitations (e.g., inconsistent results, imprecision - wide confidence intervals or methodological flaws - e.g., ...

AU - Nair, Prakash V.. AU - Zink, Karen A.. AU - Michalek, Joel E.. AU - Holcomb, John B.. AU - Schreiber, Martin. PY - 2011/8. Y1 - 2011/8. N2 - Background: Administration of high transfusion ratios in patients not requiring massive transfusion might be harmful. We aimed to determine the effect of high ratios of fresh frozen plasma (FFP) and platelets (PLT) to packed red blood cells (PRBC) in nonmassively transfused patients. Methods: Records of 1,788 transfused trauma patients who received 1:2 ratio of FFP:PRBCs or a ,1:2 ratio PLT:PRBCs had significantly decreased ICU-free days and ventilator-free days. Conclusions: FFP:PRBC and PLT:PRBC ratios were not associated with in-hospital mortality. Depending on the threshold analyzed, a high ratio of FFP:PRBC and PLT:PRBC transfusion was associated with fewer ...
The treatment of the anemic patient often requires accurate type and cross-matching of red blood cells and an effective adminstration plan. This lecture will focus on patient examplesand case-based discussions to understand which patient are good candidates for red blood cell transfusion, how to plan for appropriate transfusion therapy, and create a protocol for watchful administration. Transfusion reactions will be discussed and as well as the step on how to attempt to mitigate them.

We are hoping that the IgG is enough to combat the antibodies in his blood causing his ...
JENKINTOWN, Pa., March 5, 2007 - The National Comprehensive Cancer Network (NCCN) announces important updates to the NCCN Cancer- and Treatment-Related Anemia Guidelines. The NCCN Clinical Practice Guidelines in Oncology™ are widely recognized and applied as the standard of care in oncology in the United States in both the community and the academic practice settings. A significant issue the panel addressed was the results of a trial by Amgen, Inc. studying the use of Aranesp® (darbepoetin alfa) in patients with cancer-related anemia. In this large, multicenter, randomized, placebo-controlled study, darbepoetin failed to reduce red blood cell transfusions in patients with active cancer who have anemia but are not on chemotherapy or radiation therapy. The study also showed higher mortality in patients receiving darbepoetin. As a result, the NCCN panel added a statement to the Adverse Effects of Erythropoietic Therapy section of the guidelines. It states that, until new research evidence ...
Hemoglobin (Hb) transfusion thresholds are established in intensive care units. A restrictive transfusion threshold (Hb 70-75 g/l) is recommended in septic patients, and a liberal transfusion threshold (Hb 90 g/l) for cardiogenic shock. It is unclear whether these historically adopted transfusion thresholds meet the challenges of individual patients. We evaluated microvascular flow index (MFI) and proportion of perfused vessels (PPV) in the sublingual microcirculation with CytoCam-IDF microscopy and near-infrared spectroscopy (NIRS). A study team-independent, treating intensivist assigned a total of 64 patients to 1 of 2 two transfusion thresholds, 43 patients to the Hb 75 g/l threshold and 21 patients to the Hb 90 g/l threshold, at a surgical intensive care unit. We performed microcirculatory measurements 1 h before and 1 h after transfusion of 1 unit of red blood cells. Microcirculatory flow variables correlated negatively with pre-transfusion flow variables (ΔMFI: ρ = − 0.821, p | 0.001; ΔPPV:

METHODS: One hundred ninety-two consecutive children aged five years or less who underwent cardiac operations using cardiopulmonary bypass and who received red blood cells for priming the cardiopulmonary bypass circuit comprised ...
TY - JOUR. T1 - Anemia, red blood cell transfusions, and necrotizing enterocolitis. AU - Maheshwari, Akhil. AU - Patel, Ravi M.. AU - Christensen, Robert D.. PY - 2018/2/1. Y1 - 2018/2/1. N2 - In the past 15 years, multiple clinical studies have identified a temporal association between red blood cell (RBC) transfusions and necrotizing enterocolitis (NEC). With some variability, most of these studies indicate that up to one-third of all cases of NEC involving very low-birth weight infants may occur within 24-48 h after receiving a RBC transfusion. There is also evidence that the risk of such transfusion-associated NEC may be higher in infants transfused with the greatest severity of anemia. In this article, we summarize the clinical evidence pertaining to these issues; specifically, the contribution of RBC transfusions, and the contribution of severity of underlying anemia, to the pathogenesis of a type of NEC potentially termed, transfusion/anemia-associated NEC.. AB - In the past 15 years, ...
Red blood cell concentrate transfusion strategies utilised at a tertiary-level paediatric intensive care unit: A descriptive study on impact and cost
To the Editor:. I read with great interest the excellent article by Furnary and colleagues1 detailing an analysis of aprotinin and acute dialysis-dependent renal failure in cardiac surgery patients. Their multivariate analysis has demonstrated that increasing perioperative red blood cell transfusion, rather than aprotinin, is an independent risk factor for acute renal failure after cardiac surgery.. The data analysis as presented, however, does not account for angiotensin blockade in the presence of aprotinin, a described significant risk factor for perioperative renal injury.2 Consequently, if a significant percentage of the aprotinin cohort were exposed to angiotensin-converting enzyme inhibition, it might confound the results of the multivariate analysis. If the data for this variable are readily available, it would be interesting see if this potential confounder could have had any significant statistical effect.. Furthermore, the authors state in their discussion that meta-analysis of ...
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 ...
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 ...
The shelf-life of stored red blood cells (RBCs) is typically 42 and 35 days for human and canine RBCs, respectively. Given that blood is a precious and limited resource, both human and veterinary blood banks typically dispense the oldest RBC units first to reduce wastage. However, accumulating evidence suggests that transfusion of RBCs stored ≥ 14 days is associated with increased rates of morbidity and mortality in hospitalized human patients. In our study of healthy dogs receiving autologous RBC transfusions stored for 7 (fresh) and 28 (old) days, administration of old, but not fresh, RBC units was associated with a pro-inflammatory cytokine response, exemplified by monocyte chemoattractant protein (MCP)-1, and accompanied by increased neutrophil counts and decreased platelet counts.. We propose to evaluate markers of inflammation, hemolysis, and endothelial activation in a randomized clinical trial in which client-owned dogs with primary immune-mediated hemolytic anemia (IMHA) and ...

Cardiopulmonary bypass (CPB) induces hemodilutional anemia, which frequently requires the transfusion of blood products. The objective of this study was to evaluate oxygen delivery and consumption and clinical outcome in low risk patients who were allocated to an hematocrit (Hct) of 20% versus 25% during normothermic CPB for elective coronary artery bypass graft (CABG) surgery. This study was a prospective, randomized and controlled trial. Patients were subjected to normothermic CPB (35 to 36°C) and were observed until discharge from the intensive care unit (ICU). Outcome measures were calculated whole body oxygen delivery, oxygen consumption and clinical outcome. A nonparametric multivariate analysis of variance for repeated measurements and small sample sizes was performed. In a total of 54 patients (25% Hct, n = 28; 20% Hct, n = 26), calculated oxygen delivery (p = 0.11), oxygen consumption (p = 0.06) and blood lactate (p = 0.60) were not significantly different between groups.

Patients scheduled to undergo elective spine surgery were included. More than 50% of the patients had an American Society of Anesthesiologists physical status of II or III. Exclusion criteria were exclusive cervical spine surgery, one-level laminectomy, and polytrauma. Clinical management was at the discretion of the attending anesthesiologists and surgeons. In the operating room, patients were continuously monitored with electrocardioscopy, blood pressure monitoring, pulse oximetry, capnography, and esophageal temperature monitoring. A Bair Hugger device (Arizant, Eden Prairie, MN) was used, and fluids were warmed. Anesthesia was induced with propofol (1.5-2.5 mg/kg), sufentanil (15 μg), and atracurium (0.7 mg/kg) and was maintained by a continuous infusion of sufentanil and atracurium, with desflurane in a 50%-50% vol/vol O2-N2O gas mixture. The rate of the sufentanil infusion and the inspired concentration of desflurane were adjusted to maintain mean blood pressure between 50 and 70 mm Hg ...

Doctors are still working on a cure for MDS, though there are many ways to manage the disease. Patients with very low risk who do not need blood transfusions may be able to go without treatment for years, as long as they are checked regularly by a doctor. Other patients need more aggressive therapies. One treatment regimen that has worked for some patients is high doses of chemotherapy followed by a stem cell transplant. Other MDS treatments aim to reduce the need for blood transfusions, decrease the risk of infection and increase quality of life.. Blood transfusions - Some patients may need red cell to relieve symptoms of fatigue and shortness of breath. Blood transfusions increase the number of normal red blood cells in circulation, helping to relieve anemia. Platelet transfusions may be given to prevent or stop bleeding if platelet counts are very low..

HealthDay News) -- Red blood cell transfusions from young or female donors may lead to lower survival rates for recipients, according to a new Canadian study.. These results are intriguing and suggest that if you require a transfusion, your clinical outcome may be affected by the blood donors age and sex, said the studys senior author, Dr. Dean Fergusson. Hes director of the clinical epidemiology program at the Ottawa Hospital in Canada.. However, it is important to remember that our study was observational in nature, which means it cannot be considered definitive evidence, Fergusson said.. The researchers looked at blood transfusions at Ottawa Hospital between 2006 and 2013. The researchers linked more than 30,000 blood recipients with almost 81,000 donors.. The recipients health was followed for an average of just over two years.. Getting red blood cells from a woman instead of a man was linked with an 8 percent greater risk of death from any cause per unit of blood transfused, the ...
BACKGROUND: The aim of this study was to investigate the effects of red blood cell (RBC) transfusion on the hemorrheologic properties and microcirculatory hemodynamics in anemic hematology outpatients receiving 2 to 4 RBC units of either fresh (leukoreduced storage for less than 1 week) or aged (leukoreduced storage for 3-4 weeks) RBCs.. STUDY DESIGN AND METHODS: Measurements were performed before and 30 minutes after RBC transfusion in hematology outpatients. Leukoreduced RBC suspensions were stored in saline-adenine-glucose-mannitol (SAGM) additive solution. Whole blood viscosity was measured using Couette low-shear viscometry, RBC deformability and aggregability were measured using laser-assisted optical rotational cell analysis, and microcirculatory density and perfusion were assessed using sidestream dark field imaging.. RESULTS: One group of patients (n = 10) received a median (interquartile range) of 3 (2-3) RBC bags that were stored for 7 (5-7) days (fresh) and the other group of ...

43 NCCN Guidelines for Patients ® : Myelodysplastic Syndromes, 2018 5 Treatment guide Lower-risk MDS with anemia The goal is to increase red blood cell counts and lessen the need for red blood cell transfusions. Doctors often assess the response about 2 to 4 months after the start of treatment with lenalidomide. If tests do not show a treatment response, then your next options are the same as those listed for MDS without del(5q). If tests show a response, you should continue this treatment until it stops working or side effects get too severe. Over time, your doctor may lower the dose of lenalidomide to lessen the side effects. (See page 33 for more details about lenalidomide.) Treatment options for MDS without del(5q) If tests show serum EPO ≤500 mU/mL, treatment with blood cell growth factors is recommended. The two main options are epoetin alfa and darbepoetin alfa. These drugs are red blood cell growth factors- also called ESAs. ESAs act like EPO and stimulate the body to make more red ...
EPOGEN® (epoetin alfa) is used to treat a lower than normal number of red blood cells (anemia) caused by chronic kidney disease in patients on dialysis to reduce or avoid the need for red blood cell transfusions.

♦ Treatment of anaemia has changed substantially since the early 1990s♦ Although massive transfusion may be necessary, trauma surgeons have modified their practice to provide aggressive control of haemorrhage, prevent hypothermia and acidosis, optimize haemodynamic management in intensive care units, and rationalize transfusion support in severely injured patients. The result has been an improvement in the outcomes of these patients♦ Given the importance of early intervention in the care of the injured, understanding the physiology and true indications for early massive transfusion in trauma care has the potential to save many lives.
Finally, after months of waiting & hoping, Josef was diagnosed with idiopathic aplastic anemia. To date, in the last 8 months, hes had about 23 platelet transfusions & 8 red blood cell transfusions. We tried steroids twice in 5 day bouts, with no change except in his white cell count a little. After numerous times in the hospital attempting to put in an IV and having his veins burst due to the low platelets, we decided to graduate to a more secure mode; he had surgery to put in a port for his transfusions. Around this time we began seeing a naturopath/chiropractic on a weekly basis. She began adjusting Josef every week, put him on a strict gluten-free, low sugar, organic diet, and got him on a herb/supplement regimen. We tried to treat his body naturally but ran short on time due to the iron overload concern. A couple months later we finally had to move ahead with a treatment plan. In April 2008 we underwent an immunosuppresive therapy of ATG, cyclosporin & prednisone (chemotherapy). While ...
Pivotal phase 3 data demonstrated treatment with luspatercept resulted in statistically significant increased red blood cell transfusion independence compared with placebo.
Hospitalization, possibly with intensive care and red blood cell transfusions, may be necessary depending on the severity of the disease process. Supplemental oxygen therapy may be necessary. Your veterinarian may discuss discontinuing any recent medications which could trigger IMHA. If an infection is suspected, an appropriate medication for the infection will be given. High doses of steroid medications (such as prednisone or dexamethasone) are commonly given to help control the immune attack on the red blood cells. Additional immunosuppressive drugs may also be needed, especially in more severe cases. Because the red blood cell destruction can result in blood clots, anticoagulant drugs like aspirin may be needed. Newer advanced treatments like blood purification are being investigated and are sometimes recommended in severe cases.. Once immunosuppressive therapy is started, response to treatment is expected within 1 to7 days if the medications are effective. Additional medications are often ...
I was supposed to have had an exit interview to be released from SCCA on Friday, October 10, which was subsequently changed to Monday, October 13. However, my neutrophil counts have been bouncing around. From over 1.0, they fell to .56 last Friday (almost neutropenic), but bounced back up to .95 a day or two later. My platelet count has been steadily declining to 12,000 on Friday, but it bounced up to 20,000 a day later and then started falling again. Dr. Holmberg consequently indicated I should stay in Seattle and be monitored at SCCA another couple of weeks to October 24. She prescribed G-CSF yesterday, which brought my neutrophil and white count up to the normal range today. I also received a red blood cell transfusion today because my hematocrit had dropped to 26%. Although, it was up to 27% today before the transfusion, it has slowly but consistently trended downward. I also received today an IL-11 (Neumega) shot to encourage platelet growth. The dosage was based on body weight, and I ...
