T he Rh blood group system is one of the most polymorphic and antigenic blood group systems. It is second only to ABO in importance in blood transfusion and is well known as a primary cause of hemolytic disease of the fetus and newborn (HDFN). The principal antigen is D, and the terms Rh positive and Rh negative refer to the presence or absence of D antigen. Caucasians of European extraction ha...

Background: ABO blood group antigens may play a role in the pathophysiology of certain diseases. Several studies have investigated the relation between blood group and autoimmune disorders. In this research, we evaluated the associations between ABO blood types and rhesus (Rh) factor in pemphigus patients.Methods: In this case-control, hospital-based study, we evaluated the prevalence of blood ...

The Rh blood group system is one of the most polymorphic and immunogenic systems known in humans. In the past decade, intense investigation has yielded considerable knowledge of the molecular background of this system. The genes encoding 2 distinct Rh proteins that carry C or c together with either E or e antigens, and the D antigen, have been cloned, and the molecular bases of many of the anti...

background: transfusion is the mainstay treatment of patients with thalassemia major and occasionally in thalassemia intermediate. alloimmunization is an unwanted side effect of blood transfusion. the present study intended to determine the frequency of alloimmunization in patients with β- thalassemia major and thalassemia intermediate in southwest iran. patients and methods: this was a cross-s...

rhd antigen is the most immunogenic and clinically significant antigen of red blood cells after abo system. it has historically been associated with hemolytic disease of the newborn (hdn) which is now routinely prevented by the administration of polyclonal anti-d immunoglobulin. this management of hdn has proven to be one of the most successful cases of prophylactic treatment based on antibody ...
