Delivering integrated care after sexual violence in the Democratic Republic of the Congo.

In the eastern Democratic Republic of the Congo, ongoing armed conflict increases the incidence of gender-based violence (GBV) and presents a distinct and major barrier to care delivery for all survivors of GBV. A specific challenge is providing emergency contraception, HIV prophylaxis and treatment for sexually transmitted infections to all survivors within 72 hours of violence. To address the multiple barriers to providing this time-sensitive medical care, Global Strategies and Panzi Hospital implemented the Prevention Pack Program. The Prevention Pack is a pre-packaged post-rape medical kit containing antiretroviral post-exposure prophylaxis, antibiotics for treatment of sexually transmitted infections and emergency contraception. The Prevention Pack Program combines community sensitisation about post-rape medical care with the provision of Prevention Packs and the implementation of a cloud-based and Global Positioning System (GPS)-enabled inventory management system. The Panzi Hospital gender-based violence team implemented the Prevention Pack Program at Panzi Hospital and 12 rural clinics in the South Kivu Province. The data manager took GPS coordinates of each site, provided an initial stock of Prevention Packs and then called all sites daily to determine demand for post-rape care and Prevention Pack consumption. Inventory data were entered into the GPS-enabled cloud-based inventory management system. Project personnel used the consumption rate, trends and geolocation of sites to guide Prevention Pack restocking strategy. Between 2013 and 2017, a total of 8206 individuals presented for care following rape at the study sites. Of the 1414 individuals who presented in the rural areas, 1211 (85.6%) did so within the first 72 hours of reported rape. Care was delivered continuously and without a single stockout of medication across all sites. The Prevention Pack Program provided timely and consistent access to emergency contraception, HIV prophylaxis and treatment for sexually transmitted infections for rape survivors in the eastern Democratic Republic of the Congo.

Association between maternal and infant class I and II HLA alleles and of their concordance with the risk of perinatal HIV type 1 transmission.

We aimed to investigate the influence of class I and class II HLA specificities and of the concordance between maternal and infant HLA on vertical HIV-1 transmission. HLA typing of samples from mothers and infants enrolled in the Ariel study, a perinatal HIV-1 transmission cohort including 203 mother-infant pairs, was performed by serological and molecular methods. HLA effects were evaluated alone and by multivariate modeling considering also other known predictors of perinatal HIV-1 transmission (maternal viral load, antiretroviral therapy, duration of rupture of membranes, and histological chorioamnionitis). Modest associations were seen with specific HLA markers (increased risk with infant B67 and B58 and maternal DR1; decreased risk with maternal B12), but these were not statistically significant after adjusting for multiple comparisons. Mother-infant concordance at any class I locus was a strong predictor of transmission (odds ratio [OR], 4.16; p = 0.028). Transmission was not associated with class II concordance. Class I HLA concordance retained its importance after adjusting for maternal viral load, antiretroviral therapy, duration of rupture of membranes or histological chorioamnionitis. In multivariate modeling, only class I concordance (OR, 3.59; p = 0.069) and chorioamnionitis (OR, 3.79; p = 0.030) were retained as independent predictors of transmission. HLA alleles, and in particular the class I concordance between maternal and neonatal HLA, may regulate the risk of perinatal HIV-1 transmission.
