Determination of ABO Blood Groups and Rh phenotypes Among Sudanese Patients Infected with Helicobacter pylori – Khartoum State

Abstract

This is a descriptive cross-section study has been carried out in period from March to June 2014 to determine the frequencies of ABO blood group and Rh phenotype among Sudanese population infected with H. pylori in Omdurman Teaching Hospital. One hundred (100) blood samples were collected from unrelated individuals, 45 were males and 55 were females, whose age range between 11 to 75 years. Samples were tested for H. pylori by using Rapid H. pylori Antibody test and also, tested for ABO blood group and Rh phenotype by using slide and tube methods. The frequencies of this study showed the blood group O (46%) followed by group B (29%), group A (23%) and the lowest proportion is noticed in AB blood group (2%).The possible phenotype found that cDe (39%) was highest observed percent frequency is followed by CcDe (27%), ce (11%), CDe (8%), cDEe(8%), CDe (3%), Cce (2%), cD (1%), and CcDEe (1%). The result of the study showed there an association between ABO blood group and H. pylori infection. The results showed variation in infection with H. pylori according to gender that found females more prone to infection than males (55% respectively 45%).
