Introduction Most national guidelines for the prevention of mother-to-child transmission of HIV in Europe updated between 2001 and 2010 recommend vaginal deliveries for women with undetectable or very low viral load (VL). Our aim was to explore the impact of these new guidelines on the rates of vaginal deliveries among HIV-positive women in Europe.

Methods In a pooled analysis of data on HIV-positive pregnant women enrolled in the Swiss Mother & Child HIV Cohort Study and the European Collaborative Study 2000 to 2010, deliveries were classified as occurring pre- or postpublication of national guidelines recommending vaginal delivery.

Results Overall, 2663 women with 3013 deliveries were included from 10 countries; 28% women were diagnosed with HIV during pregnancy. Combination antiretroviral therapy was used in most pregnancies (2020, 73%), starting during the first or second trimester in 78% and during the third trimester in 22%; in 25% pregnancies, the woman conceived on combination antiretroviral therapy. Overall, in 86% pregnancies, a VL < 400 copies per milliliter was achieved before delivery. The proportion of vaginal deliveries increased from 17% (414/2377) before the change in guidelines to 52% (313/600) after; elective Caesarean section rates decreased from 65% to 27%. The proportion of women with undetectable VL having a Caesarean section was 55% after implementation of new guidelines. We observed a decrease of late preterm deliveries from 16% (377/2354) before to 7% (42/599) after the change in guidelines (P < 0.001).

Conclusion There are still missed opportunities for women with HIV to fully suppress their VL and to deliver vaginally in Europe.

Improvements in virological control among women conceiving on cART in Western Europe

Abstract Among 396 HIV-infected women conceiving on combination antiretroviral therapy and enrolled in the European Collaborative Study in 2000–2011, the proportion with virological failure (>200 copies/ml after ≥24 weeks of treatment) declined substantially from 34% in 2000–2001 to 3% in 2010–2011. In adjusted analyses, younger women and those with at least two children were at increased risk of virological failure, highlighting the importance of close monitoring and adherence support.

Use of combination neonatal prophylaxis for the prevention of mother-to-child transmission of HIV infection in European high-risk infants.

Objectives To evaluate use of combination neonatal prophylaxis (CNP) in infants at high risk for mother-to-child transmission(MTCT) of HIV in Europe and investigate whether CNP is more effective in preventing MTCT than single drug neonatal prophylaxis (SNP).

Design Individual patient-data meta-analysis across eight observational studies.

Methods Factors associated with CNP receipt and with MTCT were explored by logistic regression using data from non-breastfed infants, born between 1996 and 2010 and at high risk for MTCT.

Results In 5285 mother-infant pairs, 1463 (27.7%) had no antenatal or intrapartum antiretroviral prophylaxis, 915 (17.3%) had only intrapartum prophylaxis and 2907 (55.0%) mothers had detectable delivery viral load despite receiving antenatal antiretroviral therapy. Any neonatal prophylaxis was administered to 4623 (87.5%) infants altogether; 1105 (23.9%) received CNP. Factors significantly associated with the receipt of CNP were later calendar birth year, no elective caesarean section, maternal CD4 cell count less than 200 cells/μl, maternal delivery viral load more than 1000 copies/ml, no antenatal antiretroviral therapy, receipt of intrapartum single-dose nevirapine and cohort. After adjustment, absence of neonatal prophylaxis was associated with higher risk of MTCT compared to neonatal prophylaxis [adjusted odds ratio (aOR) 2.29; 95% confidence interval (95% CI) 1.46-2.59; P < 0.0001]. Further, there was no association between CNP and MTCT compared to SNP (aOR 1.41; 95% CI 0.97-2.5; P = 0.07).

Conclusion In this European population, CNP use is increasing and associated with presence of MTCT risk factors. The finding of no observed difference in MTCT risk between one drug and CNP may reflect residual confounding or the fact that CNP may be effective only in a subgroup of infants rather than the whole population of high-risk infants.
