ABSTRACT
OBJECTIVE: To compare the efficacy of assisted reproductive technology (ART) in women infected with human immunodeficiency virus type 1 (HIV-1) versus HIV-negative controls. DESIGN: Retrospective case-control study. SETTING: University hospital ART unit. PATIENT(S): Eighty-two women infected with HIV-1 and 82 women as seronegative controls. INTERVENTION(S): Ovarian stimulation, oocytes retrieval, standard in vitro fertilization (IVF) or intracytoplasmic sperm injection, embryo transfer. MAIN OUTCOME MEASURE(S): Clinical pregnancies and live-birth rates. RESULT(S): After oocyte retrieval, all women infected with HIV-1 infected were matched 1:1 to HIV-negative controls according to the following criteria: date of ART attempt, age, parity, main cause of infertility, ART technique, and rank of attempt. Only the first IVF cycle during the study period was considered for each couple. We found no statistically significant differences between the two groups for ovarian stimulation data, fertilization rate, or average number of embryos transferred. The clinical pregnancy rate per transfer was statistically significantly lower for the cases compared with the controls (12% vs. 32%), as were the implantation rate (10% vs. 21%) and the live-birth rate (7% vs. 19%). CONCLUSION(S): In one of the largest studies to pair six factors that influence the results of ART, HIV infection in women was associated with poorer outcomes after ART. These results suggest that women with controlled HIV-1-infection should be counseled not to delay ART in cases of self-insemination failure or other causes of infertility. Fertility preservation by vitrification of oocytes in women whose pregnancy should be delayed may be an important future consideration.

We studied 1139 mother-infant pairs where the mother had had at least one vaginal swab in the month before delivery and their babies had had gastric and ear swabs taken immediately after delivery. The prevalence of vaginal carriage of Staphylococcus aureus was 5.9% among 1139 pregnant women within 1 month of delivery. The colonisation rate of S. aureus in newborns was tenfold higher when the mother was a vaginal carrier than when she was not (31.3% vs. 2.7%; relative risk 11.6 [95% CI 7.0, 19.2]; P < 0.05). Among carriers, delivery by caesarean section compared with the vaginal route, significantly decreased the likelihood of S. aureus colonisation in the newborns (15.4% vs. 41.5%; relative risk 0.35 [95% CI 0.14, 0.98]; P < 0.03). No S. aureus colonisation was detected in the mothers of 58% of the colonised newborns suggesting extra-delivery colonisation routes. Consequences for newborns were unclear as only one case of S. aureus neonatal sepsis was observed.
