The Impact of ABO Blood Types on Spontaneous Miscarriage and Cytomegalovirus Infection Iraq

Introduction: Blood groups are linked to diseases as receptors for pathogens, influencing spontaneous abortion. Understanding these factors is crucial for effective risk factor management. Objective: To elucidate the connection between blood types, Rh factor, and the incidence of spontaneous abortion while also examining its association with the dissemination of antibodies to cytomegalovirus. Methods: A cross-sectional study involving 200 pregnant women found that cytomegalovirus seroprevalence was higher in those experiencing spontaneous abortion compared to those not. Rh factor and blood types were also assessed using agglutination. Results: The prevalence of CMV percentage was statistically significant (P≤ 0.001) in the abortion group CMV IgG (93.0%, 20.0%) and CMV IgM (22.0%,1.0%). Blood group O+ was the most prevalent among pregnant women who had experienced abortion and CMV IgG latent infection, whereas blood group B+ was the most common in the healthy group. Additionally, the Rh factor did not demonstrate any statistical significance about abortion or the spread of the virus. Conclusion: CMV is widespread among pregnant women in the Diyala Governorate. Also, Blood group O+ is associated with an increased risk of spontaneous abortion and is also linked to a higher likelihood of CMV IgG latent viral infection in aborted women.
