background & aims: mistyping either a donor or a recipient can lead to transfusion with abo incompatible blood which results in severe intravascular hemolysis and may even result in the death of the recipient. abo phenotype is one of the essential tests in immunohematology. eighty percent of blood group a and ab persons are subtype a1 and a1b, respectively. the other 20% of these blood groups a...
Haemovigilance is a system with standard program to cover the entire transfusion chain, monitor, evaluate and analyse the data to improve patients’ safety. We report the implemented haemovigilance system in hospitals and transfusion reactions (TR) in Iran. Methods and Materials: This was a prospective descriptive study. The national reporting system for transfusion incidents was introduced in ...

Rabbits immunized intravenously with living culture or nucleoproteins of non-hemolytic streptococci react to subsequent intracutaneous inoculations with homologous streptococci with smaller and harder lesions than are shown by normal animals similarly inoculated; and they do not develop the general manifestations of hypersensitiveness such as are shown by animals previously inoculated into the ...
Autoimmune hemolytic anemia (AIHA) is caused by hemolysis induced by the reaction of autoantibodies with red blood cells (RBCs) [1-4]. Events that lead to AIHA include extravascular hemolysis caused by phagocytosis of erythrocyte-bound IgG in the spleen (hemolytic mechanism), activation of polyclonal B cells, reactions induced by molecular mimicry of exogenous antigens, breakdown of immune tole...
1. Hemolytic streptococcus has been found in 100 per cent of the throats of patients with scarlet fever during the 1st week of the disease. 2. The average length of time that these organisms are present in the throat varies from 10 to 20 days. 3. No morphological or cultural characteristics peculiar to the hemolytic streptococcus from scarlet fever can be demonstrated. 4. Ten immune sera have b...
Background and Objectives: Thalassemia is a hereditary hemolytic anemia requiring life-long transfusion treatment. The frequent blood transfusion has some side effects, including immunologic reaetions and non-immunologics such as iron overload and transmission of some infections such as HBV, HCV and HIV. This cross-sectional study was aimed to investigate the transfusion effects in patients ref...
