To evaluate pregnancy outcomes in a cohort of HIV-infected women receiving triple antiretroviral therapy (ART) for prevention of mother-to-child-transmission. A retrospective cohort study with review of records of 3273 HIV-positive women receiving prenatal care in Malawi and Mozambique from July 2005 to December 2009 was conducted in Drug Resource Enhancement Against AIDS and Malnutrition (DREAM) centers. Patients were offered nevirapine-based triple ART initiated in pregnancy until 6 months postpartum. Main outcome measures were maternal mortality, abortion/stillbirth, prematurity, and low birth weight. Maternal mortality was 1.2% (42/3273): 7.4% in 68 women with no antenatal ART and 0.7% in 1370 with at least 90 days of antenatal ART [P < 0.001; odds ratio (OR) 0.29 (95% confidence interval [CI] 0.14-0.96]. Abortion/stillbirth was 5.2% (169/3273): 26.5% in 68 women with no ART and 5.0% in 1370 women with at least 90 days of antenatal ART [P < 0.001; OR 0.39 (95% CI 0.27-0.57)]. Prematurity was 19.1%: 70% in 10 women with no antenatal ART and 8.5% in 1330 women with at least 90 days of antenatal ART [P < 0.001; OR 0.15 (95% CI 0.14-0.19)]. Low birth weight was 11.5% (57/496) and not associated with ART duration. The protective effect of antenatal ART against mortality, fetal demise, and prematurity was independent of CD4 strata. Multivariate analysis for BMI, CD4 cell count, virus load, days in care, predelivery length of ART, and hemoglobin demonstrated an independent association between predelivery length of ART and CD4 with maternal mortality, abortion/stillbirth, and prematurity. ART toxicities were infrequent (5.2%). Antenatal triple ART reduces adverse pregnancy outcomes in HIV-infected women.

Reduction of HIV-1 breast-feeding transmission remains a challenge for prevention of pediatric infections in Sub-Saharan Africa. Provision of formula decreases transmission but often increases child mortality in this setting. A prospective observational cohort study of HIV-1 exposed infants of mothers receiving pre and postnatal medical care at Drug Resource Enhancement Against AIDS and Malnutrition centers in Mozambique was conducted. Live-born infants of HIV-1-infected women receiving medical care were enrolled. HIV-1 testing was performed at 1, 6, and 12 months of age using branched DNA. Mothers were counseled to breast-feed exclusively for 6 months and were provided HAART antenatally and postnatally for the first 6 months. Women with CD4 cell counts less than 350/cmm at baseline continued HAART indefinitely. Of 341 infants followed from birth, 313 mother-infant pairs (92%) completed 6 months and 283 (83%) completed 12 months of follow-up. HIV-1 diagnosis was ascertained in 287 infants (84%) including 4 who died. There were 8 cases of HIV-1 transmission: 4 of 341 (1.2%) at 1 month, 2 of 313 (0.6%) at 6 months, and 2 of 276 (0.7%) at 12 months (cumulative rate: 2.8%). Two mothers (0.6%) and 11 infants (3.2%) died. Maternal and infant mortality rates were 587 of 100,000 and 33 of 1000, while country rates are 1000 of 100,000 and 101 of 1000. HIV risk reduction was 93% and HIV-free survival at 12 months was 94%. Late postnatal transmission of HIV-1 is significantly decreased by maternal use of HAART with high infant survival rates up to 12 months of age.

Optimized preventive strategies are needed to reach the objective of eliminating pediatric AIDS. This study aimed to define the determinants of residual HIV transmission in the context of maternal antiretroviral therapy (ART) administration to pregnant women, to assess infant safety of this strategy, and to evaluate its impact on maternal disease. A total of 311 HIV-infected pregnant women were enrolled in Malawi in an observational study and received a nevirapine-based regimen from week 25 of gestation until 6 months after delivery (end of breastfeeding period) if their CD4+ count was > 350/mm³ at baseline (n = 147), or indefinitely if they met the criteria for treatment (n. 164). Mother/child pairs were followed until 2 years after delivery. The Kaplan-Meier method was used to estimate HIV transmission, maternal disease progression, and survival at 24 months. The rate of HIV infant infection was 3.2% [95% confidence intervals (CI) 1.0-5.4]. Six of the 8 transmissions occurred among mothers with baseline CD4+ count > 350/mm³. HIV-free survival of children was 85.8% (95% CI 81.4-90.1). Children born to mothers with baseline CD4+ count < 350/mm³ were at increased risk of death (hazard ratio 2.6, 95% CI 1.1-6.1). Among women who had stopped treatment the risk of progression to CD4+ count < 350/mm³ was 20.6% (95% CI 9.2-31.9) by 18 months of drug discontinuation. HIV transmission in this cohort was rare however, it occurred in a significative proportion among women with high CD4+ counts. Strategies to improve treatment adherence should be implemented to further reduce HIV transmission. Mortality in the uninfected exposed children was the major determinant of HIV-free survival and was associated to maternal disease stage. Given the considerable proportion of women reaching the criteria for treatment within 18 months of drug discontinuation, life-long ART administration to HIV-infected women should be considered.

Background: The prevalence of frailty at population-level is expected to increase in Europe, changing the focus of Public Health. Here, we report on the activities of the A3 Action Group, focusing on managing frailty and supporting healthy ageing at community level. Methods: A three-phased search strategy was used to select papers published between January 2016 and May 2018. In the third phase, the first manuscript draft was sent to all A3-Action Group members who were invited to suggest additional contributions to be included in the narrative review process. Results: A total of 56 papers were included in this report. The A3 Action Group developed three multidimensional tools predicting short–medium term adverse outcomes. Multiple factors were highlighted by the group as useful for healthcare planning: malnutrition, polypharmacy, impairment of physical function and social isolation were targeted to mitigate frailty and its consequences. Studies focused on the management of frailty highlighted that tailored interventions can improve physical performance and reduce adverse outcomes. Conclusions: This review shows the importance of taking a multifaceted approach when addressing frailty at community level. From a Public Health perspective, it is vital to identify factors that contribute to successful health and social care interventions and to the health systems sustainability.
