Background: HIV incidence among young women in sub-Saharan Africa remains high and their inclusion in vaccine and cure efforts is crucial. We aimed to establish a cohort of young women detected during Fiebig stage I acute HIV infection in whom treatment was initiated immediately after diagnosis to advance research in this high-risk group., Methods: 945 women aged 18-23 years in KwaZulu-Natal, South Africa, who were HIV uninfected and sexually active consented to HIV-1 RNA testing twice a week and biological sampling and risk assessment every 3 months during participation in a 48-96 week life-skills and job-readiness programme. We analysed the effect of immediate combination antiretroviral therapy (ART) on viraemia and immune responses, sexual risk behaviour, and the effect of the socioeconomic intervention., Findings: 42 women were diagnosed with acute HIV infection between Dec 1, 2012, and June 30, 2016, (incidence 8·2 per 100 person-years, 95% CI 5·9-11·1), of whom 36 (86%) were diagnosed in Fiebig stage I infection with a median initial viral load of 2·97 log 10 copies per mL (IQR 2·42-3·85). 23 of these 36 women started ART at a median of 1 day (1-1) after detection, which limited the median peak viral load to 4·22 log 10 copies per mL (3·27-4·83) and the CD4 nadir to 685 cells per μL (561-802). ART also suppressed viral load (to <20 copies per mL) within a median of 16 days (12-26) and, in 20 (87%) of 23 women, prevented seroconversion, as shown with western blotting. 385 women completed the 48 week socioeconomic intervention, of whom 231 were followed up for 1 year. 202 (87%) of these 231 women were placed in jobs, returned to school, or started a business., Interpretation: Frequent HIV screening combined with a socioeconomic intervention facilitated sampling and risk assessment before and after infection. In addition to detection of acute infection and immediate treatment, we established a cohort optimised for prevention and cure research., Funding: Bill & Melinda Gates Foundation, National Institute of Allergy and Infectious Diseases, International AIDS Vaccine Initiative, Wellcome Trust, Howard Hughes Medical Institute., (Copyright © 2018 Elsevier Ltd.

Twenty-one women (propositi) who expressed serious concerns about changes in body habitus during highly active antiretroviral therapy (HAART) were evaluated by thorough physical examination, anthropometric measurements, and serum lipid and endocrine assays. The same evaluations were carried out in a comparison group of 21 women who received HAART but did not complain of changes in habitus. No significant demographic differences were found between the propositi and the comparison group, nor were there significant differences in CD4 count or plasma viral load (PVL) between the two groups. Lipid analyses were also performed on plasma obtained prior to HAART from 12 of the women. The frequency of changes reported by the 21 propositi were increase in abdominal size (90%), increase in breast size (71%), weight gain of >5 kg (43%), peripheral fat wasting (43%), buttock fat wasting (38%) and development of cervicodorsal fat pad (19%). A subset of patients in the comparison group experienced increase in abdominal size (29%) and weight gain >5 kg (19%), but none experienced clinically detectable peripheral or buttock fat wasting, increased breast size, or development of cervicodorsal fat pads. Mean waist circumference, waist-to-hip ratios (WHR), body fat, and body mass index (BMI) were above the desirable range for women in both propositi and the comparison group. Levels of total cholesterol, triglycerides, low-density lipoprotein (LDL) cholesterol, and high-density lipoprotein (HDL) cholesterol associated with increased cardiovascular risk were found in 48%, 62%, 45%, and 33%. respectively, of the propositi, with similar findings in the comparison group. Fasting insulin levels were elevated in 4 propositi and 6 of the comparison group; mean insulin levels were within the normal range for both groups. In the comparison of lipids for the subset of patients before and after HAART therapy, HAART was associated with significant increases in total cholesterol, apolipoprotein B, and HDL cholesterol. Changes in body habitus caused by redistribution of fat occur commonly in women receiving HAART. Serum lipid abnormalities also are common during HAART and appear to be as frequent in women who do not experience clinically apparent body fat redistribution as in those who do. The observed changes in body fat distribution and in serum lipid levels are alterations that have been strongly correlated with increased risk for cardiovascular disease. Therefore, an understanding of the basis of these phenomena, and the risks with which they may be associated in this population, will be important for therapeutic decision making in women with HIV disease.
