Prophylaxie anti-D dans l’incompatibilité fœto-maternelle érythrocytaire en Tunisie

Abstract

Generalization of postnatal prophylaxis using anti-D immunoglobulins decreased the incidence of erythrocyte fetal-maternal incompatibility (EFMI) in the Rhesus system. Few recent studies have investigated the situation of anti-D prophylaxis in Tunisia and its effects on maternal and neonatal health. The aim of this study was therefore to analyze the situation of anti-D prophylaxis in Tunisia to detect defects and propose solutions. We conducted a retrospective descriptive study of IFME cases in the rhesus system in the Department of Medicine and Neonatal Resuscitation of the Tunis Maternity and Neonatology Center (CMNT) during an 8-year period from 1January 2006to 31December 2015. We collected 51cases of IFME. The prevalence of IFME was 3.4per 10000live births; 41% of the patients were transferred in utero and they were from the northwest of the country (17%). The rate of women with a history of at least one spontaneous miscarriage (SCF) was 45%. In 42% of the cases, pregnancies were monitored at local clinics. The search for irregular agglutinins (RAI) was performed in 86% of the women studied. RAI was positive in 97% of the cases. Anti-D prophylaxis was correctly performed in only 27% of the cases. The systematic prophylaxis of the third trimester and a systematic Kleihauer test must be combined with postpartum prophylaxis to better identify dysfunctions and improve the application of the recommendations.
