Distribution of ABO/Rhesus Blood Groups Among Hepatitis B and C Virus (HBV Ag, HCV Ab) Positive Patients in Anbar Providence, Iraq

This study aimed to retrospectively investigate the prevalence of Hepatitis B Virus (HBV) and Hepatitis C Virus (HCV) infections among blood donors at Anbar Blood Bank in Iraq. The study also explored the correlation between ABO and Rh blood groups with Transfusion-Transmissible Infections (TTIs) and sociodemographic factors and cross-sectional retrospective study was conducted on 100 blood donors at Anbar Blood Bank from March 24, 2023, to June 21, 2023. Inclusion criteria encompassed HBV and HCV-positive patients who provided consent, while exclusion criteria included individuals without HBV and HCV infections. Blood samples (5 mL) were collected, and tests for TTI markers (HBV, HCV) and ABO and Rh blood grouping were performed using enzyme-linked immunosorbent assay (ELISA) and slide method, respectively. Sociodemographic data, TTI marker results, and ABO and Rh blood types were recorded for analysis. Descriptive analysis of sociodemographic data was performed, and a chi-square test was employed to assess the correlation between ABO and Rh blood groups with TTI markers and sociodemographic factors (Age, sex, and living area). Statistical significance was set at P<0.05. The results revealed a male predominance (71%), with the majority aged between 20-30 years (39%) and residing in rural areas (52%). The most common blood group was O+ (39%), while AB- was the least prevalent (0%). In terms of viral infections, 80% of participants were found to be infected with HBs Ag, and 20% with HCV Ab. Notably, blood group O+ exhibited the highest infection rates for both HBs (28%) and HCV (11%), while blood group A- demonstrated the lowest HBs infection rate (3%) and no HCV infection. The study provides valuable insights into the prevalence of HBV and HCV infections among blood donors in Anbar, Iraq. Additionally, correlations between ABO and Rh blood groups, TTI markers, and sociodemographic factors were explored. The findings contribute to the understanding of transfusion safety and may inform blood screening and donor selection protocols.
