In utero transfusion of BLOOD into the FETUS for the treatment of FETAL DISEASES, such as fetal erythroblastosis (ERYTHROBLASTOSIS, FETAL).
The internal resistance of the BLOOD to shear forces. The in vitro measure of whole blood viscosity is of limited clinical utility because it bears little relationship to the actual viscosity within the circulation, but an increase in the viscosity of circulating blood can contribute to morbidity in patients suffering from disorders such as SICKLE CELL ANEMIA and POLYCYTHEMIA.
The transfer of blood components such as erythrocytes, leukocytes, platelets, and plasma from a donor to a recipient or back to the donor. This process differs from the procedures undertaken in PLASMAPHERESIS and types of CYTAPHERESIS; (PLATELETPHERESIS and LEUKAPHERESIS) where, following the removal of plasma or the specific cell components, the remainder is transfused back to the donor.

The process by which fetal Rh+ erythrocytes enter the circulation of an Rh- mother, causing her to produce IMMUNOGLOBULIN G antibodies, which can cross the placenta and destroy the erythrocytes of Rh+ fetuses. Rh isoimmunization can also be caused by BLOOD TRANSFUSION with mismatched blood.
Removal of plasma and replacement with various fluids, e.g., fresh frozen plasma, plasma protein fractions (PPF), albumin preparations, dextran solutions, saline. Used in treatment of autoimmune diseases, immune complex diseases, diseases of excess plasma factors, and other conditions.
Any liquid used to replace blood plasma, usually a saline solution, often with serum albumins, dextrans or other preparations. These substances do not enhance the oxygen- carrying capacity of blood, but merely replace the volume. They are also used to treat dehydration.
A term used pathologically to describe BILIRUBIN staining of the BASAL GANGLIA; BRAIN STEM; and CEREBELLUM and clinically to describe a syndrome associated with HYPERBILIRUBINEMIA. Clinical features include athetosis, MUSCLE SPASTICITY or hypotonia, impaired vertical gaze, and DEAFNESS. Nonconjugated bilirubin enters the brain and acts as a neurotoxin, often in association with conditions that impair the BLOOD-BRAIN BARRIER (e.g., SEPSIS). This condition occurs primarily in neonates (INFANT, NEWBORN), but may rarely occur in adults. (Menkes, Textbook of Child Neurology, 5th ed, p613)
An antigenic mismatch between donor and recipient blood. Antibodies present in the recipient's serum may be directed against antigens in the donor product. Such a mismatch may result in a transfusion reaction in which, for example, donor blood is hemolyzed. (From Saunders Dictionary & Encyclopedia of Laboratory Medicine and Technology, 1984).

An alkaloid derived from the bark of the cinchona tree. It is used as an antimalarial drug, and is the active ingredient in extracts of the cinchona that have been used for that purpose since before 1633. Quinine is also a mild antipyretic and analgesic and has been used in common cold preparations for that purpose. It was used commonly and as a bitter and flavoring agent, and is still useful for the treatment of babesiosis. Quinine is also useful in some muscular disorders, especially nocturnal leg cramps and myotonia congenita, because of its direct effects on muscle membrane and sodium channels. The mechanisms of its antimalarial effects are not well understood.

O-raffinose cross-linking markedly reduces systemic and renal vasoconstrictor effects of unmodified human hemoglobin. (1/169)

The hemodynamic effects of a 20% exchange-transfusion with different solutions of highly purified human hemoglobin A-zero (A0) were evaluated. We compared unmodified hemoglobin with hemoglobin cross-linked with O-raffinose. Unmodified hemoglobin increased systemic vascular resistance and mean arterial pressure more than the O-raffinose cross-linked hemoglobin solution (by approximately 45% and approximately 14%, respectively). Unmodified hemoglobin markedly reduced cardiac output (CO) by approximately 21%, whereas CO was unaffected by the O-raffinose cross-linked hemoglobin solution. Unmodified and O-raffinose cross-linked hemoglobin solutions increased mean arterial pressure to comparable extents ( approximately 14% and approximately 9%, respectively). Unmodified hemoglobin increased renal vascular resistance 2-fold and reduced the glomerular filtration rate by 58%. In marked contrast, the O-raffinose cross-linked hemoglobin had no deleterious effect on the glomerular filtration rate, renal blood flow, or renal vascular resistance. The extents to which unmodified and O-raffinose cross-linked hemoglobin solutions inactivated nitric oxide also were compared using three separate in vitro assays: platelet nitric oxide release, nitric oxide-stimulated platelet cGMP production, and endothelium-derived relaxing factor-mediated inhibition of platelet aggregation. Unmodified hemoglobin inactivated or oxidized nitric oxide to a greater extent than the O-raffinose cross-linked hemoglobin solutions in all three assays. In summary, O-raffinose cross-linking substantially reduced the systemic vasoconstriction and the decrease in CO induced by unmodified hemoglobin and eliminated the deleterious effects of unmodified hemoglobin on renal hemodynamics and function. We hypothesize that O-raffinose cross-linking reduces the degree of oxidation of nitric oxide and that this contributes to the reduced vasoactivity of this modified hemoglobin.  (+info)

Efficacy of recombinant human Hb by 31P-NMR during isovolemic total exchange transfusion. (2/169)

The ability of recombinant human Hb (rHb1.1), which is being developed as an oxygen therapeutic, to support metabolism was measured by in vivo 31P-NMR surface coil spectroscopy of the rat abdomen in control animals and in animals subjected to isovolemic exchange transfusion to hematocrit of <3% with human serum albumin or 5 g/dl rHb1.1. No significant changes in metabolite levels were observed in control animals for up to 6 h. The albumin-exchange experiments, however, resulted in a more than eightfold increase in Pi and a 50% drop in phosphocreatine and ATP within 40 min. The tissue pH dropped from 7.4 to 6.8. The decrease in high-energy phosphates obeyed Michaelis-Menten kinetics, with a Michaelis-Menten constant of 3% as the hematocrit at which a 50% drop in high-energy phosphates was observed. Exchange transfusion with rHb1.1 resulted in no significant drop in high-energy phosphates, no rise in Pi, and no change in tissue pH from 7.35 +/- 0.15 for up to 5 h after exchange. By these criteria, rHb1.1 at a plasma Hb concentration of approximately 5 g/dl after total exchange transfusion was able to sustain energy metabolism of gut tissue at levels indistinguishable from control rats with a threefold higher total Hb level in erythrocytes.  (+info)

Serum malondialdehyde concentration in babies with hyperbilirubinaemia. (3/169)

AIM: To determine lipid peroxide concentrations in the first 10 days of life. METHODS: Malondialdehyde concentrations were investigated in neonates with or without hyperbilirubinaemia during the first 10 days of life. RESULTS: Serum malondialdehyde concentrations were higher in infants with hyperbilirubinaemia than in controls. A positive correlation was found between malondialdehyde and bilirubin concentrations in the study group. When the study group was categorised according to the presence of haemolysis, a significant correlation was found between malondialdehyde and bilirubin concentrations in those infants with hyperbilirubinaemia due to haemolysis. There was no such correlation in those without haemolysis. CONCLUSION: Exchange transfusion rapidly produces variable changes in pro-oxidant and antioxidant plasma concentrations in neonates, which may be responsible for free radical metabolism. The fall in malondialdehyde concentration is probably directly related to its exogenous removal by exchange transfusion.  (+info)

Sickle cell disease and aortic valve replacement: use of cardiopulmonary bypass, partial exchange transfusion, platelet sequestration, and continuous hemofiltration. (4/169)

Sickle cell disease in patients undergoing open heart procedures presents a multitude of challenges to the medical staff. With improved techniques of cardiopulmonary bypass, surgery, and anesthesia for treating patients with sickle cell disease, perfusionists will likely encounter patients with this genetic disorder on a more frequent basis. A 40-year-old black woman was admitted to our institution with recurrent Staphylococcus epidermidis and sepsis. She underwent transesophageal echocardiography and cardiac catheterization and was subsequently diagnosed with severe aortic insufficiency. The aortic valve was replaced. Herein, we report our experience in the preoperative, perioperative, and postoperative management of this patient. We present a concise update on the current literature and techniques used by others in similar cases, and we provide a brief section on future considerations to assist fellow practitioners in recognizing this disease and meeting the accompanying challenges.  (+info)

Long-term survival of hamster hearts in presensitized rats. (5/169)

We transplanted hamster hearts into rats that had been sensitized to hamster cardiac grafts 5 days earlier as a model for discordant xenotransplantation. Sensitized rats had high serum levels of elicited anti-donor IgM and IgG that caused hyperacute rejection. Transient complement inhibition with cobra venom factor (CVF) plus daily and continuing cyclosporin A (CyA) prevented hyperacute rejection. However, grafts underwent delayed xenograft rejection (DXR). DXR involved IgG and associated Ab-dependent cell-mediated rejection, because depletion of IgG or Ab-dependent cell-mediated rejection-associated effector cells prolonged graft survival and the serum-mediated Ab-dependent cell-mediated cytotoxicity in vitro. Blood exchange in combination with CVF/CyA treatment dramatically decreased the level of preexisting Abs, but DXR still occurred in association with the return of Abs. Splenectomy and cyclophosphamide acted synergistically to delay Ab return, and when combined with blood exchange/CVF/CyA facilitated long-term survival of grafts. These grafts survived in the presence of anti-donor IgM, IgG, and complement that precipitated rejection of naive hearts, indicating that accommodation (survival in the presence of anti-graft Abs and complement) had occurred. We attribute the long-term survival to the removal of preexisting anti-donor Abs and therapy that attenuated the rate of Ab return. Under such conditions, the surviving hearts showed expression in endothelial cells and smooth muscle cells of protective genes and an intragraft Th2 immune response. Th2 responses and protective genes are associated with resistance to IgM- and IgG-mediated, complement-dependent and -independent forms of rejection.  (+info)

Simvastatin. A new therapeutic approach for Smith-Lemli-Opitz syndrome. (6/169)

The Smith-Lemli-Opitz syndrome (SLOS) is caused by deficient Delta(7)-dehydrocholesterol reductase, which catalyzes the final step of the cholesterol biosynthetic pathway, resulting in low cholesterol and high concentrations of its direct precursors 7-dehydrocholesterol (7DHC) and 8DHC. We hypothesized that i) 7DHC and 8DHC accumulation contributes to the poor outcome of SLOS patients and ii) blood exchange transfusions with hydroxymethylglutaryl (HMG)-CoA reductase inhibition would improve the precursor-to-cholesterol ratio and may improve the clinical outcome of SLO patients. First, an in vitro study was performed to study sterol exchange between plasma and erythrocyte membranes. Second, several exchange transfusions were carried out in vivo in two SLOS patients. Third, simvastatin was given for 23 and 14 months to two patients. The in vitro results illustrated rapid sterol exchange between plasma and erythrocyte membranes. The effect of exchange transfusion was impressive and prompt but the effect on plasma sterol levels lasted only for 3 days. In contrast, simvastatin treatment for several months demonstrated a lasting improvement of the precursor-to-cholesterol ratio in plasma, erythrocyte membranes, and cerebrospinal fluid (CSF). Plasma precursor concentrations decreased to 28 and 33% of the initial level, respectively, whereas the cholesterol concentration normalized by a more than twofold increase. During the follow-up period all morphometric parameters improved. The therapy was well tolerated and no unwanted clinical side effects occurred. This is the first study in which the blood cholesterol level in SLOS patients is normalized with a simultaneous significant decrease in precursor levels. There was a lasting biochemical improvement with encouraging clinical improvement. Statin therapy is a promising novel approach in SLOS that deserves further studies in larger series of patients.  (+info)

Clinical applications of the continuous flow blood separator machine. (7/169)

The NCl/IBM or Aminco Continuous Flow Blood Separator Machine is a safe apparatus for the selective removal or exchange of either packed red blood cells, leucocyte-rich or platelet-rich layers or plasma. Abnormal fractions from any of these layers may be collected and discarded. Normal constituents may be collected for therapeutic uses. The wide scope of its applications includes important uses in clinical immunology: temporary provision of good leucocytes or platelets; harvesting of immune leucocytes (preparation of transfer factor at up to 10 units per harvest); removal of cryo- or macro-globulins, immune complexes or blocking factors; replacement therapy for antibody or complement deficiencies. Examples are given of such uses together with some of the medical problems so far encountered.  (+info)

Dynamics of glomerular ultrafiltration in the rat. VIII. Effects of hematocrit. (8/169)

This study was undertaken in an effort to examine the effects of selective variations in systemic hematocrit on the preglomerular, glomerular, and postglomerular micocirculation in the rat. By isovolemic exchange transfusions, systemic hematocrit (control 51 ml/100 ml) was either reduced (21 ml/100 ml, N equal 7 rats) or elevated (62 ml/100 ml, N equal 7). Single nephron glomerular filtration rate varied inversely and filtration fraction varied directly with the changes in hematocrit. The fall in filtration fraction with decreased hematocrit was due to a decline in the measured glomerular transcapillary hydraulic pressure difference and to a marked increased in the initial glomerular plasma flow rate. Afferent (RA)and efferent (RE) arteriolar resistance declined with the fall in hematocrit; RA fell proportionately more than did RE. The rise in filtration fraction with the elevation in hematocrit was due to a marked increase in in part due to a relatively greater rise in RE than in RA. These findings provide an attractive explanation for the general tendency for filtration fraction to vary directly with hematocrit in anemic and polycythemic states in man.  (+info)

TY - JOUR. T1 - Effects of neonatal polycythemia and partial exchange transfusion on cardiac function. T2 - An echocardiographic study. AU - Murphy, D. J.. AU - Reller, M. D.. AU - Meyer, R. A.. AU - Kaplan, S.. PY - 1985. Y1 - 1985. N2 - Although infants with neonatal polycythemia and hyperviscosity often present with cardiorespiratory distress, little information is available regarding the cardiac function of such babies before or after partial exchange transfusion. To assess cardiac function, we performed M-mode echocardiograms in 19 asymptomatic newborn infants (4 to 12 hours of age) who had venous hematocrits greater than 65%. The echocardiograms were performed immediately prior to and following partial exchange transfusion and were repeated at 48 hours of age. Eighteen matched newborn controls also underwent echocardiography within the first 12 hours of life and again at 48 hours. Polycythemic newborns had elevated right ventricular preejection period to right ventricular ejection time ...

Background: The incidence of glucose-6-phosphate dehydrogenase (G-6-PD) deficiency in Iran is estimated at 10-14.9%. The donor blood in blood banks is not screened routinely for this enzyme deficiency and such blood may be used for neonatal exchange transfusion.Objective: To study the effect of G-6-PD deficient blood in neonatal exchange blood transfusion.Methods: In a prospective study, serum bilirubin was checked before and 6 hours after exchange transfusion in three hundred and fifty consecutive neonates who were admitted to Nemazee Hospital, Neonatal Ward. Hemoglobin, direct Coombs test, direct bilirubin, reticulocyte count, blood group of neonates and mothers, G-6-PD of neonates and the blood used for exchange transfusion were also checked. For analysis of the data, 102 neonates who weighed more than 2500 gr and with no evidence of hemolysis, liver disease or sepsis were divided into three groups; Group I: patients in this group were exchanged with G-6-PD deficient blood. Group IIa: patients in

NICE asks for views on plans to recommend the Spectra Optia Apheresis System which automatically replaces sickle red blood cells with healthy red blood cells
The primary endpoint evaluated the mean ratio of the Actual Fraction of Cells Remaining (FCRa: as measured by Post-Procedure % HbS) to the Predicted Fraction of Cells Remaining (FCRp: as predicted by the Spectra Optia system FCR algorithm multiplied by the Pre-Procedure % HbS), in the evaluable population (60 pts). The pre-defined range for the mean ratio of the FCRa to the FCRp was 0.75 to 1.25 ...
Transfusions do not come without risks, most commonly iron overload, infection, and alloimmunization. Alloimmunization occurs when the recipient produces alloantibodies, making future donor matching and transfusions more difficult.2 Therefore, benefits of therapy must outweigh the risks. Prior to transfusing, sickle-negative donor blood is phenotypically matched and leukocyte reduced (to avoid febrile reactions).2 Two different types of transfusions exist, simple and exchange. Simple transfusions deliver additional units of blood without removal of sickle cells. This can increase blood viscosity and is best reserved for when the hemoglobin level is less than 8 g/dL. Exchange transfusions are more complicated and involve removing sickle cells and replacing them with normal cells. This can be done manually or via automated red cell exchange and is associated with decreased incidence of iron overload and number of sickle cells.2,3 Exchange transfusions are warranted if the hemoglobin level is high ...
Background. Exchange transfusion (ET) has biologic plausibility an adjunct to antimalarial drugs in treating severe malaria and has been used for decades despite limited evidence of its efficacy in improving survival. We examined the efficacy of ET
Some doctors may be concerned that, if the new AAP guidelines are indeed followed, the number of neonates requiring phototherapy or exchange transfusion will increase. Others will find that the implications for change may be minimal. For example, in our practice, from 1994 till the present, we started phototherapy at STB concentrations suggested by the 1994 guidelines for considering phototherapy, rather than mandating it. Thus the upper limit set by the AAP in 2004 for an STB concentration of 428 μmol/l (25 mg/dl) will not mean, for us, that we will be performing more exchange transfusions or treating more babies under phototherapy. Certainly, although there is room for individualisation, we do feel that the AAPs new cut-off points for starting phototherapy and performing exchange transfusion should probably not be exceeded. Should there be an abundance of risk factors or if clinical judgment deems it necessary, there is no reason not to start phototherapy earlier or at lower concentrations ...

The authors have reviewed the autopsies of 8 patients with adenosine-deaminase-deficient severe combined immunodeficiency disease (ADA-SCID). Several new findings in nonlymphoid organs, including kidney and adrenal gland, and chondro-osseous tissue indicate the multisystem nature of this disorder. Examination of renal tissue in 7 of 8 cases showed mesangial sclerosis. This was confirmed in 3 cases by electron microscopy. One case, treated with multiple erythrocyte partial exchange transfusions for several years, had no mesangial sclerosis. Six of 8 cases showed adrenal-gland cortical sclerosis. Chondro-osseous tissue from vertebrae and costochondral junctions of 4 cases examined showed typical alterations previously reported in ADA-SCID such as short growth plates with few proliferating and some hypertrophic chondrocytes. The authors report the new observations of necrotic chondrocytes, as well as large amounts of cellular debris. These changes were not observed in the 2 other patients examined, who

It is still unclear how mother-to-child HCV transmission occurs in the perinatal period, and our present findings may help to shed some light on the route of infection. During the perinatal period, there are two possible major routes of HCV transmission from mother to child: placental infection and birth canal infection. Placental infection results from active transport of virus from mother to child, or from micro-transfusion of virus due to placental membrane damage. In all of the three brothers, blood exchange between the fetus and the mother through the placenta had been good, because anti-HCV antibody (immunoglobulin G) had been transferred to all fetuses and was detected in the umbilical blood at birth in all cases. However, only the second child had been infected with HCV. Negativity for HCV RNA in the umbilical blood of this child was different from the viral titer in the serum of his mother, which indicated a very high level of HCV RNA, as shown in Table 1. Thus placental infection by ...

The new registrar queries why intravenous immunoglobulin is not being used first in an attempt to avoid exchange transfusion. ...
Rh immune-globulin acts like a vaccine. It prevents the mothers body from making any Rh antibodies that could cause serious health problems in the newborn or affect a future pregnancy.. A woman also might get a dose of Rh immune-globulin if she has a miscarriage, an amniocentesis, or any bleeding during pregnancy.. If a doctor finds that a woman has already developed Rh antibodies, her pregnancy will be closely watched to make sure that those levels are not too high.. In rare cases, if the incompatibility is severe and a baby is in danger, the baby can get special blood transfusions called exchange transfusions either before birth (intrauterine fetal transfusions) or after delivery. Exchange transfusions replace the babys blood with blood with Rh-negative blood cells. This stabilizes the level of red blood cells and minimizes damage from Rh antibodies already in the babys bloodstream.. Thanks to the success rate of Rh immune-globulin shots, exchange transfusions in Rh-incompatible pregnancies ...
The COBE Spectra system uses centrifugal technology to separate whole blood into its major components.

The laboratory and clinical management of alloimmunized in pregnancy has been investigated according to a protocol currently in use in Örebro region. A 12 year epidemiological study showed the prevalence of alloimmunization to be 0.57% in this Swedish populationwith a 0.24% incidence of clinically significant antibodies that can induce haemolytic disease of the newborn (HDN). Rh antibodies, predominantly anti-D, are still the causes of most cases of severe HDN in which 45/47 babies required exchange transfusion. During the studyperiod, 14 mothers were successfully treated with plasma exchange during pregnancy owing to high anti-D antibody concentrations. Only two other blood group syswms, Kell and Duffy, besides Rh affected newborns to alloimmunized mothers to such a grade that exchange transfusion of the newborns was necessary. All generally accepted for the fetus clinically nonsignificant antibodies were also followed and shown not to cause HDN. In 3 instances, anti-D was detected in partial ...
Alyssa is having PDA (Patent Ductus Arteriosus) surgery tonight. This will help her blood route to her lungs. We are waiting for her oxygen levels to stabilize and then they will start the surgery. The doctor will let us know once it is finished and he says that he has done a surgery like this before on a baby smaller than Alyssa. I can only have hope and faith that God will see her through this. This isnt the only bump in the road we learned about tonight. They put her under phototheraphy lights. The doctor said that if her bilirubin levels do not decrease that she would require an extremely risky exchange transfusion. We are praying that her levels decrease and we will find out tonight if she will need the exchange transfusion. ...
Over the last 10 years or so, SCBUs have become much more parent-friendly, encouraging maximum involvement with the babies. Routine gowns and masks are gone and parents are encouraged to help with care as much as possible. Cuddling and skin-to-skin contact, also known as Kangaroo care, are seen as beneficial for all but the frailest (very tiny babies are exhausted by the stimulus of being handled; or larger critically ill infants). Less stressful ways of delivering high-technology medicine to tiny patients have been devised: sensors to measure blood oxygen levels through the skin, for example; and ways of reducing the amount of blood taken for tests.. Some major problems of the NICU have almost disappeared. Exchange transfusions, in which all the blood is removed and replaced, are rare now. Rhesus incompatibility (a difference in blood groups) between mother and baby is largely preventable, and was the most common cause for exchange transfusion in the past. However, breathing difficulties, ...
We first introduced Circulator readers to Kane Lamberson in our Summer 2011 issue (click HERE for that story). At that time, Kane had not yet received a diagnosis. The family moved out of state for a while, but returned to Springfield and got in touch with us. Lets catch up with Kane now.. Within five minutes of Kanes birth, we thought there was a problem, Dave Lamberson said of his and wife Lizs son, born in April 2010. He was very pale and was hooked up to a ventilator almost immediately.. Doctors said their newborn would live 12 to 36 hours. He was a very sick little boy, Liz said. His spleen and liver were enlarged, and his bilirubin levels spiked higher than a case of jaundice. He had a blueberry muffin rash all over his body -multiple bluish or purplish marks due to a formation of blood cell clusters. We had no idea what was wrong.. An exchange transfusion - which removes some of the patients blood and replaces it with fresh donor blood - was performed to replace one-quarter of ...
Since the cause of the initial episode is unknown, prevention is not possible and treatment is currently confined to prevention of recurrence. This is most commonly attempted by a chronic transfusion program aiming to maintain HbS levels below 30 per cent and preferably below 20 per cent. This is initiated by exchange transfusion followed by regular top-up transfusions. Prevention of accumulation of iron requires regular chelation therapy with desferrioxamine, and difficulties with venous access may require installation of a permanent port. Despite the use of white cell and platelet-poor blood, minor incompatibilities are common and severe transfusion reactions may occur. The required duration of treatment is unknown, and high recurrence rates after stopping transfusion programs (even after 10 years) have led to the conclusion that treatment may be needed for life. There is a need to understand the risk factors for the initial stroke so that this may be avoided if possible. Investigation and ...

navigated external liquidity pressures from the COVID-19 shock through partial exchange rate adjustment combined with de facto capital flow management measures and foreign-currency (FC) restrictions.. Fitch opined that the oil-rich African country supported the level of its external reserves with disbursed external official loans - lately, Nigeria got USD3.36 billion worth of loan from the International Monetary Fund (IMF) to further boost infrastructural development.. On the flip side, the credit agencys report revealed that unfulfilled FC demand could constitute a drain on reserves once FC supply is further relaxed by CBN.. Reportedly, the stock of outstanding non-resident holdings of CBN open-market operation (OMO) bills was around USD10 billion in August 2020, equivalent to 27.99% of external reserves (USD35.73 billion) in September 2020.. In Fitchs view, further tightening of FC supply for trade and financial transactions could harm output growth and exacerbate inflationary ...

Ten and a half years ago, when our 21-month-old daughter was diagnosed with Acute Lymphoblastic Leukemia, Scott and I were told to be thankful it was ALL and not some other kind of cancer. We were thankful, strange as it was to feel glad about anything related to a cancer diagnosis. We knew that the prognosis was better for kids with ALL than with other types of cancer.. But we were a full week into treatment before we found out how very good the prognosis actually was. Jane had started the week with two complete blood exchanges, purging her body of all the cancerous white blood cells that had escaped her bone marrow and were coursing through her tiny veins. She had made it through the first terrible week of chemotherapy-the fevers, the vomiting, the countless needle sticks. One week down, years to go. The head of the hem/onc department came in to meet us, and he asked us, rather professorially, what our goal was with Janes treatment.. Remission? I asked. He smiled in obvious amusement. Yes, ...

In contrast to recently drawn conclusions,31 this systematic review and meta-analysis invites further investigation into the merits of prophylactic transfusion in pregnant women with SCD. Although constrained by methodologic limitations of original study designs, the analysis suggested a reduction in vaso-occlusive pain episodes, maternal mortality, overall pulmonary complications, pulmonary embolism, neonatal mortality, and preterm birth, favoring institution of prophylactic transfusion.. The potential of prophylactic transfusion to reduce adverse pregnancy outcomes in women with SCD stems from its capacity to remedy SCD-driven physiologic derangements through (1) correction of anemia, enhancing RBC oxygen-carrying capacity; (2) reduction in the proportion of sickle hemoglobin carrying erythrocytes, diminishing vaso-occlusive episodes; (3) reduction in blood viscosity, if provided via RBC exchange transfusion; and to a lesser extent, (4) suppression of endogenous erythropoiesis.32,33 Although ...

We report three infants with DS-TAM and HF who were treated with exchange transfusion (ET) followed by low-dose cytarabine (LD-CA). All of them survived without developing liver failure, acute leukemia, or other serious adverse events. Our results suggest that this combination treatment with ET and LD-CA would be safe, tolerable and effective as an novel approach for DS-TAM patients with HF..

Objective: The study evaluated the efficacy of phototherapy and 20% albumin infusion to reduce total serum bilirubin (TSB) in neonates with severe hyperbilirubinemia. The primary outcome was a reduction of TSB at the end of treatment. The secondary outcomes were the need for exchange transfusion, inpatient mortality, neurological outcomes at discharge, and development outcomes at 12-months follow-up. Results: One hundred and eighteen neonates were randomly assigned to phototherapy and 20% albumin (n = 59) and phototherapy and saline (n = 69). The median age at admission was 5 (interquartile range (IQR) 3-6) days, and the median gestation was 36 (IQR 36-38) weeks. No significant differences were found in the change in TSB (Mann-Whitney U =609, p = 0.98) and rate of change in TSB per hour after treatment (Mann-Whitney U = 540, p = 0.39) between the two groups. There were no significant differences between the two groups in the proportion of participants who required exchange transfusion (χ2 (2) = 0.36, p

The Kidd blood group is clinically significant because the Jk antibodies could cause acute and delayed transfusion reactions aswell as hemolytic disease of newborn (HDN). worth of 11.4 mg/dL, a reticulocyte count number of 14.9% and a complete bilirubin of 46.1 mg/dL, a primary bilirubin of just one 1.1 mg/dL and a solid positive result (+++) in the immediate Coombs test. As a complete consequence of the id of abnormal antibody in the maternal serum, anti-Jkb was discovered, that was also within the eluate created from infants blood. Despite the aggressive treatment with exchange transfusion and rigorous phototherapy, the patient died of intractable seizure and acute renal failure around the fourth day of admission. Therefore, pediatricians should be aware of the clinical courses of hemolytic jaundice due to anti-Jkb, and they should be ready to treat this disease with active therapeutic interventions. and are BMS-354825 alternate, autosomally inherited codominant alleles.

Dr. Hans Martin Steingassner (veterinarian and textbook-writer). Deficient excretion - the start of a vicious circle. A large number of obese animals are therefore toxic waste dumps. Approximately 70 percent of degenerative joint diseases originate from problems with excretion. There is more: accumulation of waste products, excess weight, joint problems and therefore the accompanying aversion to exercise form an ever-increasing vicious circle. As a result because the skin then also has to assume part of the excretory function, allergies may also manifest themselves if there is genetic predisposition. The connective tissue is intended to help the cells exchange substances: blood vessels and nerves end here whilst the lymphatic vessels start here. The connective tissue is a molecular sieve and the largest organ in the body in its entirety. If this molecular sieve is blocked, nothing will happen any longer, including the information received from a homeopathic remedy. Despite the correct choice of ...
Abstract:. Bovine leukemia virus (BLV) is associated with the most common neoplastic disease of cattle. BLV has a silent dissemination in the herd due to infected cell exchange, thus the concentration of BLV-infected cells in blood should play a major role in the success of viral transmission. Genes from Bovine leukocyte antigen (BoLA), the MHC system of cattle, are associated with genetic resistance and susceptibility to a wide range of diseases, and also with production traits. Some BoLA DRB3.2 allele polymorphisms in Holstein cattle have been associated with resistance or susceptibility to BLV-disease development, or with proviral load (PVL). This investigation studied 107 BLV-infected Argentinean Holstein dairy cows, all of them belonging to one herd. PVL was analysed by qPCR and animals were classified as high proviral load (HPVL, N = 88) and low proviral load (LPVL, N = 19), and BoLA DRB3.2 alleles were genotyped. Alleles BoLA DRB3.2*1501 and *1201 were significantly associated with HPVL ...
As the above examples illustrate, the science connecting wireless signals and other forms of electromagnetic radiation (EMR) with biological effects and disease has existed for decades and is extensive. In fact, there are now more than 5,000 studies that link EMR with at least 132 biological impacts and more than 50 diseases.. Humans Are Electrical Creatures. Low levels of electrical energy can affect our health because humans are electrical creatures and our biological welfare depends critically on a delicate balance of electrical activity. Our brains and hearts utilize electrical impulses to function. Doctors use EKGs to measure the electrical activity of the heart and EEGs to gauge the electrical health of the brain. Trillions of cells exchange electrical messages, which coordinate and orchestrate our body chemistry.. The key components of these biological communications, which include ions, neurons and neurotransmitters, all depend crucially on low-level electrical energy. Even the cells in ...
Sickle cell disease (SCD) increases the risk for stroke by 200 to 400 times; 5-8% of patients with SCD develop symptomatic cerebrovascular disease. Sickled cells adhere to vessel walls leading to intimal and medial damage and subsequent stenosis and occlusion. Sickle cell vasculopathy (SCV) affects small and large vessels but the distal internal carotid artery and the proximal middle cerebral arteries are the most commonly involved.. Transcranial Doppler is useful as a screening tool to predict SCV. Time averaged mean velocities ,170 cm/sec may indicate hemodynamically significant stenosis and require MR angiography for anatomic confirmation. Exchange transfusion may reverse the perfusion disturbance diagnosed by Doppler and MR angiography.. Moya moya is a description of progressive stenosis of the supraclinoid internal carotid artery with enlargement of the perforating arteries and development of collateral vessels at the circle of Willis giving rise to a puff of smoke appearance.

Ensure adequate hydration by starting intravenous fluids. Oxygenation should be checked and supplemental oxygen given if needed. Because of possible severe hemolysis, adequate hydration with alkaline solutions to keep a brisk urine flow is essential. Low-dose dopamine may help preserve renal blood flow. Monitor serial CBC, BUN, creatinine, electrolytes and urinalysis including onsite dipstick of urine for hemoglobin. Administer blood in patients with hemolysis. If major hemolysis has occurred, exchange transfusion may be performed to remove the plasma hemoglobin, in conjunction with hemodialysis to preserve renal function. Recovery is dependent on the supportive care provided, the extent of the exposure and the resulting effects of hemolysis.

1. Both the monomer arginine kinase from lobster muscle and the dimer arginine kinase from Holothuria forskali catalyse the ATP-ADP partial exchange reaction at rates equal to 3 and 0.6% of the normal rate of transphosphorylation respectively. The Mg2+-nucleotide complex is the substrate for this as it is for the kinase reaction. 2. Analogues of arginine inhibit the exchange reaction of the lobster enzyme but enhance that of the Holothuria enzyme. 3. With the lobster enzyme NO3- has no effect on the exchange reaction alone and inhibit only slightly the apparent enhancement of the exchange reaction produced by the addition of arginine. This is compatible with previous findings for this enzyme that formation of the anion-stabilized dead-end complex, enzyme-arginine-MgADP-NO3-, does not occur to any marked degree. 4. About 80% of the ADP-ATP exchange reaction of the lobster enzyme remains after inhibition with iodoacetamide. This is further decreased to 65% by the addition of L-arginine, indicating ...
The aim of this study was to develop tables for equi-carbohydrate and equi-glycaemic partial exchange of kiwifruit for glycaemic carbohydrate foods. Kiwifruit is one of the most nutrient-rich of readily available fruits, however the high content of sugars is often seen as reason to avoid fruit. The results showed that partial equi-carbohydrate substitution of foods in most carbohydrate food categories substantially increased vitamin C with little change in glycaemic impact, while equi-glycaemic partial substitution by kiwifruit could be achieved with little change in carbohydrate intake indicating that eating fresh fruit does not need have a negative glycaemic impact.. ...
