Bone marrow, spleen, liver and kidney proton transverse relaxation rates (R2), together with cardiac R2* from patients with sickle cell disease (SCD), paroxysmal nocturnal hemoglobinuria (PNH) and non-transfusion dependent thalassemia (NTDT) have been compared with a control group. Increased liver and bone marrow R2 values for the three groups of patients in comparison with the controls have be...
OBJECTIVE To delineate blood transfusion practices and outcomes in patients with major burn injury. CONTEXT Patients with major burn injury frequently require multiple blood transfusions; however, the effect of blood transfusion after major burn injury has had limited study. DESIGN Multicenter retrospective cohort analysis. SETTING Regional burn centers throughout the United States and Ca...
BACKGROUND AND OBJECTIVES anemia is a common clinical finding in intensive care units. The red blood cell transfusion is the main form of treatment, despite the associated risks. Thus, we proposed to evaluate the profile of transfusional patients in different intensive care units. METHODS prospective analysis of patients admitted in the intensive care units of a tertiary university hospital w...
BACKGROUND Recent studies show that transfusing older blood may lead to increased mortality. This raises the issue of whether transfusing fresher blood can be achieved without jeopardizing blood availability. STUDY DESIGN AND METHODS We propose a simple family of policies that is defined by a single threshold: rather than transfusing the oldest available blood that is younger than 42 days, we...
The effect of HLA matching on cadaver kidney graft survival was analysed in over 9000 transplants. Matching for HLA-A and -B accounted for an improvement of 8% in the one-year survival rate, matching for HLA-DR for 10%, and matching for HLA-B + DR for 19%. The matching effect of the HLA-B and HLA-DR loci was additive. Patients without pre-transplant transfusions had lower graft survival rates t...
BACKGROUND Sensitization to human leukocyte antigen (HLA) from red blood cell (RBC) transfusion is poorly quantified and is based on outdated, insensitive methods. The objective was to evaluate the effect of transfusion on the breadth, magnitude and specificity of HLA antibody formation using sensitive and specific methods. METHODS Transfusion, demographic and clinical data from the US Renal ...
Seventeen of 73 (23.3%) multiply transfused patients with thalassaemia major (age range, 1-39 years) tested positive for antibody to hepatitis C virus (anti-HCV). Eleven of the 24 patients regularly transfused in countries outside Britain were anti-HCV seropositive; only six of the 49 regularly transfused in Britain were seropositive. The incidence of anti-HBs and anti-HBc was similar to that o...
Kattamis, C., Syriopoulou, V., Davri-Karamouzi, Y., Demetriou, D., and Matsaniotis, N. (1974). Archives of Disease in Childhood, 49, 450. Prevalence of Au-Ag and Au-Ab in transfused children with thalassaemia in Greece. The prevalence of Australia-antigen and -antibody was studied in 196 patients with thalassaemia, aged 10 months to 14 years. Au-Ag was detected in 14 patients (7%) and Au-Ab in ...
Provision of quality care, service and blood products to patients while containing costs and the amount of blood used should be the aim of every blood bank. Therefore a prospective audit was carried out over three months to determine how efficiently blood was being used in elective surgery in the University Hospital, Kuala Lumpur. Every case with blood crossmatched was monitored to determine th...
