Background Late initiation of HIV antiretroviral therapy (ART) in pregnancy is associated with not achieving viral suppression before giving birth and increased mother-to-child transmission of HIV. We aimed to investigate virological suppression before giving birth with dolutegravir compared with efavirenz, when initiated during the third trimester. MethodsIn this randomised, open-label trial, DolPHIN-2, we recruited pregnant women in South Africa and Uganda aged at least 18 years, with untreated but confirmed HIV infection and an estimated gestation of at least 28 weeks, initiating ART in third trimester. Participants were randomly assigned (1:1) to dolutegravir-based or efavirenz-based therapy. HIV viral load was measured 7 days and 28 days after antiretroviral initiation, at 36 weeks' gestation, and at the post-partum visit (0-14 days post partum). The primary efficacy outcome was a viral load of less than 50 copies per mL at the first post-partum visit, and the primary safety outcome was the occurrence of drug-related adverse events in mothers and infants until the post-partum visit. Longer-term follow-up of mothers and infants continues. This study is registered with ClinicalTrials.gov, NCT03249181.Findings Between Jan 23, and Aug 15, 2018, we randomly assigned 268 mothers to dolutegravir (135) or efavirenz (133). All mothers and their infants were included in the safety analysis, and 250 mothers (125 in the dolutegravir group, 125 in the efavirenz group) and their infants in efficacy analyses, by intention-to-treat analyses. The median duration of maternal therapy at birth was 55 days (IQR 33-77). 89 (74%) of 120 in the dolutegravir group had viral loads less than 50 copies per mL, compared with 50 (43%) of 117 in the efavirenz group (risk ratio 1•64, 95% CI 1•31-2•06). 30 (22%) of 137 mothers in the dolutegravir group reported serious adverse events compared with 14 (11%) of 131 in the efavirenz group (p=0•013), particularly surrounding pregnancy and puerperium. We found no differences in births less than 37 weeks and less than 34 weeks gestation (16•4% vs 3•3%, across both groups). Three stillbirths in the dolutegravir group and one in the efavirenz group were considered unrelated to treatment. Three infant HIV infections were detected, all in the dolutegravir group, and were considered likely to be in-utero transmissions.Interpretation Our data support the revision to WHO guidelines recommending the transition to dolutegravir in first-line ART for all adults, regardless of pregnancy or child-bearing potential.Funding Unitaid.

BackgroundThe global transition to use of dolutegravir (DTG) in WHO-preferred regimens for HIV treatment is limited by lack of knowledge on use in pregnancy. Here we assessed the relationship between drug concentrations (pharmacokinetics, PK), including in breastmilk, and impact on viral suppression when initiated in the third trimester (T3).Methods and findingsIn DolPHIN-1, HIV-infected treatment-naïve pregnant women (28–36 weeks of gestation, age 26 (19–42), weight 67kg (45–119), all Black African) in Uganda and South Africa were randomised 1:1 to dolutegravir (DTG) or efavirenz (EFV)-containing ART until 2 weeks post-partum (2wPP), between 9th March 2017 and 16th January 2018, with follow-up until six months postpartum. The primary endpoint was pharmacokinetics of DTG in women and breastfed infants; secondary endpoints included maternal and infant safety and viral suppression. Intensive pharmacokinetic sampling of DTG was undertaken at day 14 and 2wPP following administration of a medium-fat breakfast, with additional paired sampling between maternal plasma and cord blood, breastmilk and infant plasma.No differences in median baseline maternal age, gestation (31 vs 30 weeks), weight, obstetric history, viral load (4.5 log10 copies/mL both arms) and CD4 count (343 vs 466 cells/mm3) were observed between DTG (n = 29) and EFV (n = 31) arms. Although DTG Ctrough was below the target 324ng/mL (clinical EC90) in 9/28 (32%) mothers in the third trimester, transfer across the placenta (121% of plasma concentrations) and into breastmilk (3% of plasma concentrations), coupled with slower elimination, led to significant infant plasma exposures (3–8% of maternal exposures). Both regimens were well-tolerated with no significant differences in frequency of adverse events (two on DTG-ART, one on EFV-ART, all considered unrelated to drug). No congenital abnormalities were observed. DTG resulted in significantly faster viral suppression (P = 0.02) at the 2wPP visit, with median time to <50 copies/mL of 32 vs 72 days. Limitations related to the requirement to initiate EFV-ART prior to randomisation, and to continue DTG for only two weeks postpartum.ConclusionDespite low plasma DTG exposures in the third trimester, transfer across the placenta and through breastfeeding was observed in this study, with persistence in infants likely due to slower metabolic clearance. HIV RNA suppression <50 copies/mL was twice as fast with DTG compared to EFV, suggesting DTG has potential to reduce risk of vertical transmission in mothers who are initiated on treatment late in pregnancy.Trial registrationclinicaltrials.gov NCT02245022

BackgroundMentoring is a core component of medical education and career success. There is increasing global emphasis on mentorship of young scientists in order to train and develop the next leaders in global health. However, mentoring efforts are challenged by the high clinical, research and administrative demands. We evaluated the status and nature of mentoring practices at Makerere University College of Health Sciences (MAKCHS).MethodsPre-tested, self-administered questionnaires were sent by email to all Fogarty alumni at the MAKCHS (mentors) and each of them was requested to complete and email back the questionnaire. In addition to training level and number of mentors, the questionnaires had open-ended questions covering themes such as; status of mentorship, challenges faced by mentors and strategies to improve and sustain mentorship within MAKCHS. Similarly, open-ended questionnaires were sent and received by email from all graduate students (mentees) registered with the Uganda Society for Health Scientists (USHS). Qualitative data from mentors and mentees was analyzed manually according to the pre-determined themes.ResultsTwenty- two out of 100 mentors responded (14 email and 8 hard copy responses). Up to 77% (17/22) of mentors had Master's-level training and only 18% (4/22) had doctorate-level training. About 40% of the mentors had ≥ two mentees while 27% had none. Qualitative results showed that mentors needed support in terms of training in mentoring skills and logistical/financial support to carry out successful mentorship. Junior scientists and students reported that mentorship is not yet institutionalized and it is currently occurring in an adhoc manner. There was lack of awareness of roles of mentors and mentees. The mentors mentioned the limited number of practicing mentors at the college and thus the need for training courses and guidelines for faculty members in regard to mentorship at academic institutions.ConclusionsBoth mentors and mentees were willing to improve mentorship practices at MAKCHS. There is need for institutional commitment to uphold and sustain the mentorship best practices. We recommend a collaborative approach by the stakeholders in global health promotion to build local capacity in mentoring African health professionals.

Background: Monthly use of the dapivirine vaginal ring has been shown to be safe and effective for HIV-1 prevention in nonpregnant reproductive-aged women. The impact of dapivirine on pregnancy outcomes and infant is not known. We compared pregnancy incidence and outcomes by study arm among HIV-1 uninfected women who became pregnant while participating in MTN-020/ASPIRE. Methods: ASPIRE was a randomized, double-blind, placebo controlled phase III safety and effectiveness study of the dapivirine ring for HIV-1 prevention. Sexually active women aged 18–45 from Malawi, South Africa, Uganda, and Zimbabwe were enrolled. Urine pregnancy tests were performed monthly and, if positive, study product was withheld during pregnancy and breastfeeding. Pregnancy-related outcomes included: pregnancy incidence, pregnancy outcomes (live birth, preterm birth, pregnancy loss, congenital anomalies), and infant growth. Results: Of 2,629 women enrolled in ASPIRE, 169 became pregnant during follow-up, resulting in 179 incident pregnancies and 181 pregnancy outcomes. No difference in pregnancy incidence by study arm was observed (hazard ratio=0.93; 95% CI 0.68–1.26). The distribution of pregnancy outcomes was similar by study arm, and no difference was noted in the frequency or pattern of congenital anomalies or infant growth parameters by study arm. Conclusion: Dapivirine use in the periconception period does not appear to be associated with adverse effects on pregnancy or infant outcomes. Our findings provide support for additional safety studies of the dapivirine ring throughout pregnancy.
