Bacterial Infection versus Viral Infection Preference of ABO Blood Group Phenotype Patients

抄録

Several studies have established an association between the blood group type and susceptibility to infections. This study aimed to evaluate a correlation between the blood group type and the susceptibility to infection. A total of 558 patients were enrolled in this study who attended at the Althawra Hospital, Ibb City, from March to August 2018. Blood samples were analyzed for complete blood count and blood group. We observed a high frequency of infections affecting the digestive system (26.4%), while the least affected system was the urogenital system 5.9%. Patients with A blood group exhibit an increased probability to be infected by viruses than they do for bacteria (odds ratio [OR] = 1.430; 95% confidence interval [CI] = 1.005 to 2.035; P = 0.05 and OR = 0.098; 95% CI = 0.064 to 0.148; P < 0.0001, respectively). It was observed that blood group A individuals were more susceptible to infection with hepatitis B virus than were the other groups (P = 0.041; OR = 1.704, 95% CI = 1.053–2.773). The liklihood of O blood group patients experiencing urogenital infections was less than that of non-O blood group patients one third (OR = 0.353, 95% CI = 0.158–0.789; P = 0.014). This study corroborates previous findings that demonstrated that certain blood groups are more prone to infection by one agent than are patients with other blood groups.
