OBJECTIVE: To describe the experience of four London HIV centres prescribing nevirapine (NVP) to HIV-1 infected pregnant women with respect to immunological and virological response, tolerability and pregnancy outcome. METHODS: We identified all HIV-1-infected women who received NVP as part of a triple antiretroviral regimen during pregnancy between January 1997 and September 1999. Laboratory results, clinical events, side-effects and pregnancy outcome were abstracted using a standardized proforma from the medical records. RESULTS: Forty-six women were identified, 85% of whom were black African. At initiation of NVP, the median age was 29 years and the median baseline CD4 cell count and viral load were 242 cells/microL and 4.15 log10 copies/mL, respectively. Thirty-two out of 36 women who had a plasma sample obtained at, or just prior to, delivery had an undetectable viral load (< 50 to < 400 copies/mL). Adverse events that were definitely attributed to NVP included a generalized rash (n = 2) and hepatitis (n = 2). Obstetric complications occurred in nine women (19.5%), which was not statistically different (P = 0.36) from that found in a historical (1990-96) control group 7/51 (14%). The rate of preterm delivery (13%) was similar to that previously reported in HIV-1 infected pregnant women (18%). CONCLUSIONS: NVP (as part of highly active antiretroviral therapy) reduced plasma viraemia to below the limit of detection in 89% of women. It was generally well tolerated and clinical and laboratory adverse events were infrequent. There was no evidence of an increase in obstetric complications including preterm delivery during the second and third trimesters of pregnancy.
