Pregnancy and progression to AIDS: results of the French prospective cohorts

Objective: To investigate whether pregnancy accelerates HIV-1 disease progr ession. Method: In two large French SEROCO and SEROGEST prospective cohorts of HIV infected patients, the progression to AIDS in 365 women with a known date o f HIV-1 seroconversion was examined by comparing those who delivered after HIV infection (n = 241) with those who did not become pregnant while HIV-in fected (n = 124). Results: The crude relative risk of developing AIDS associated with pregnan cy was 0.7 [95% confidence interval (CI), 0.4-1.2]. Adjustment for age at s eroconversion, the CD4+ cell percentage at entry, and the method used to da te seroconversion did not modify the results (adjusted relative risk, 0.7; 95% CI 0.4-1.2). Conclusions: No deleterious effect of pregnancy on progression from serocon version to AIDS was found. This result has important implications for the c ounselling of HIV-infected women of child-bearing age. (C) 2000 Lippincott Williams & Wilkins.
