A cohort study conducted in Kigali Rwanda in 1992-93 investigated the effect of chorioamnionitis (CAM) on pregnancy outcomes in HIV-positive pregnant women after controlling for common STDs. All pregnant women attending the prenatal clinic at the Centre Hospitalier de Kigali at 24-28 weeks gestation were offered voluntary HIV testing and STD screening. A total of 286 HIV-positive and 275 HIV-negative women were enrolled and received monthly clinical follow-up with treatment for STDs and conditions such as anemia when needed. At enrollment the two groups did not differ in terms of STD prevalence. On the basis of histologic examination of the placenta CAM was diagnosed in 27 HIV-positive women (9.8%) and 28 HIV-negative women (9.8%). Independent of HIV status there were no significant associations between CAM and age parity hepatitis B anemia STDs and CD4 lymphocyte count. Among HIV-negative women CAM was significantly associated with prematurity (relative risk (RR) 3.0; 95% confidence interval (CI) 1.5-6.3) stillbirth (RR. 4.2; 95% CI 1.6-11.0) and premature rupture of the membranes (RR 2.9; 95% CI 1.4-6.1). Among HIV-positive women the only adverse outcome significantly associated with CAM was early neonatal mortality (RR 2.0; 95% CI 1.6-11.0). The unexpectedly low rate of CAM recorded in this study is probably a result of the STD treatment and other medical services offered to study participants. This in turn suggests that control of STDs and anemia during pregnancy may represent a feasible intervention for reducing vertical HIV transmission in developing countries. Further microbiologic and histologic studies are recommended to elucidate the physiopathology of CAM in HIV-infected women during pregnancy.
