THE PIONEERING work of Aird, Bentall and Roberts demonstrated a significant excess of blood group A in patients with carcinoma of the stomach. Blood group distribution in diseases of the central nervous system has received little attention. Strang, in the only reported investigation on Parkinson's disease, found an increased incidence of blood group 0 in a series of 450 patients in Sweden. This...

A serological study was carried out to assess the prevalence of antibodies to Helicobacter pylori and compare it with the distribution of ABO blood groups. Serum samples from 402 healthy blood donors were tested with an IgG enzyme linked immunosorbent assay. There was no difference in blood groups between those who were seropositive and those who were seronegative, which suggests that blood gro...

Background. Determination of the various ABO/Rh blood group distributions and their association with malaria infection has paramount importance in the context of transfusion medicine and malaria control. Methods. Facility based cross-sectional study was conducted from February to June, 2015, to assess ABO/Rh blood groups distribution and their association with asymptomatic malaria. A structured...

Background: ABO incompatibility is the most common cause of immune hemolytic disease of the newborn (HDN) and in most cases is not dangerous. The present study aimed to determine the prevalence of ABO-HDN and its effects on neonatal blood parameters in a population of patients referred to some training hospitals in Iran. Materials and methods: In This cross-sectional study, All newborns (a tot...

In the century since the discovery of the ABO blood groups, numerous associations between ABO groups and disease have been noted. However, the selection pressures defining the ABO distributions remain uncertain. We review published information on Plasmodium falciparum infection and ABO blood groups. DNA sequence information dates the emergence and development of the group O allele to a period o...
