GENETICAL STUDIES ON THE Rh BLOOD GROUP SYSTEM

THE Rh BLOOD GROUP SYSTEM

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...

The Rh blood group system: a review

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...

Some observations on blood factors RhA, RhB and RhC of the Rh-Hr blood group system.

Rh and LW blood group antigens

History and nomenclature The Rh system is second only to the ABO system in importance in transfusion medicine because Rh antigens, especially D, are highly immunogenic and cause hemolytic disease of the fetus and newborn (HDFN) and hemolytic transfusion reactions (HTRs). HDFN was first described by a French midwife in 1609 in a set of twins, one of whom was hydropic and stillborn, whereas the o...

The relationship ABO–Rh blood group with urinary tract infections in hospitalized patients

Background and Aim: There is no consensus in the literature on the relationship between blood groups and risk of urinary tract infection (UTI). The present study was conducted to evaluated the relationship of blood groups with UTI and determine the most common bacterial cause of UTI in different blood groups. Materials and Methods: This descriptive-analytical (cross sectional) study was conduct...
