Immunological Monitoring of Pregnant Women Consulting at Menontin Hospital, one of the area hospitals in Cotonou (Benin) in 2024

Abstract

The present study began in the maternity ward and ended in the laboratory of the Mènontin Zone Hospital on pregnant women who came for prenatal consultation. To contribute to the diagnosis of fetomaternal alloimmunization, we carried out a prospective study on 156 pregnant women, considering all trimesters. The blood samples were taken on EDTA tubes and dry tubes; these samples allowed us to carry out the ABO and Rhesus grouping of these pregnant women and then search for irregular antibodies. From the analysis of the samples, it appears that women are, on average, 27 years old and mainly belong to the age group of 25-30, i.e., a percentage of 30.13%. They are primarily first-time parents, with a rate of 34.62%, then women who have never had an abortion, with a rate of 62%. The predominant blood group is group O+. Fortunately, none of these women developed irregular antibodies. This work shows the importance of monitoring pregnant women and the effectiveness of the systematic administration of anti-D gamma globulins to all Rh-negative women.
