Introduction. Transfusion Transmitted Infections (TTIs) continue to be a major risk in transfusions in many parts of the world. The transfusion-dependent β-thalassaemia patients are particularly at risk of acquiring TTIs. The current study was undertaken to estimate the prevalence of TTIs in transfusion-dependent β-thalassaemia patients. Material and Methods. A cross-sectional study of 1253 mul...

Iron chelation therapy is often used to treat iron overload in patients requiring transfusion of red blood cells (RBC). A 76-year-old man with MDS type refractory cytopenia with multilineage dysplasia, intermediate-1 IPSS risk, was referred when he became transfusion dependent. He declined infusional chelation but subsequently accepted oral therapy. Following the initiation of chelation, RBC tr...

Objective: Thalassemic patients are at risk of zinc deficiency due to various causes including desferal injection, hyperzincuria, high ferritin levels, and hepatic iron overload. We evaluate the effect of zinc supplementation on linear growth of beta-thalassemia patients. Methods: one-hundred beta-thalassemic major patients whose heights were within 3rd to l0th percentile were randomly divided ...

CONTEXT It is unclear if blood transfusion in anemic patients with acute coronary syndromes is associated with improved survival. OBJECTIVE To determine the association between blood transfusion and mortality among patients with acute coronary syndromes who develop bleeding, anemia, or both during their hospital course. DESIGN, SETTING, AND PATIENTS We analyzed 24,112 enrollees in 3 large i...

Endothelial dysfunction is characterized by abnormalities in vasoreactivity and is a marker of the extent of atherosclerosis. Cellular repair by circulating progenitor cells of ongoing vascular injury may be essential for vascular integrity and function and may limit abnormalities in vasoreactivity. Apolipoprotein E-deficient (apoE-/-) mice were splenectomized and treated with high-cholesterol ...

Frequent blood transfusions can lead to iron overload which may result in several endocrine complications especially in the absence of adequate chelation therapy. The objectives of this study are to determine the prevalence of endocrine complications in transfusion dependent thalassaemia patients and the correlation of endocrine complications with the degree of iron chelation. This retrospectiv...

We determined whether addition of hemoglobin to the plasma would inhibit endothelial-dependent dilation in brain where tight endothelial junctions limit hemoglobin extravasation. Pial arteriolar diameter was measured by intravital microscopy through closed cranial windows in anesthetized cats either without transfusion (hematocrit = 32%) or after exchange transfusion with an albumin or sebacyl-...
