ABSTRACT
BACKGROUND: Lesotho adopted the test-and-treat approach for HIV treatment in June 2016, which increased antiretroviral treatment (ART) clinic volume. We evaluated community-based vs. facility-based differentiated models of multimonth dispensing of ART among stable HIV-infected adults in Lesotho. METHODS: Thirty facilities were randomized to 3 arms, facility 3-monthly ART (3MF) (control), community ART groups (3MC), and 6-monthly community distribution points (6MCD). We estimated risk differences (RDs) between arms using population-averaged generalized estimating equations, controlling for baseline imbalances and specifying for clustering. The primary outcome was retention in ART care by intention-to-treat and virologic suppression as a secondary outcome (ClinicalTrials.gov: NCT03438370). RESULTS: A total of 5,336 participants were enrolled, with 1898, 1558, and 1880 in 3MF, 3MC, and 6MCD, respectively. Retention in ART care was not different across arms and achieved the prespecified noninferiority limit (-3.25%) between 3MC vs. 3MF (control); 6MCD vs. 3MF; and 6MCD vs. 3MC, adjusted RD = -0.1% [95% confidence interval (CI): -1.6% to 1.5%], adjusted RD = -1.3% (95% CI: -3.0% to 0.5%), and adjusted RD = -1.2% (95% CI: -2.9% to 0.5%), respectively. After 12 months, 98.6% (n = 1503), 98.1% (n = 1126), and 98.3% (n = 1285) were virally load (VL) suppressed in 3MF, 3MC, and 6MCD, respectively. There were no differences in VL between 3MC vs. control and 6MCD vs. control, risk ratio (RR) = 1.00 (95% CI: 0.98 to 1.01) and RR = 1.00 (95% CI: 0.98 to 1.01), respectively. CONCLUSIONS: There were no differences in retention and VL suppression for stable HIV-infected participants receiving multimonth dispensing of ART within community-based differentiated models when compared with the facility-based standard-of-care model.

BACKGROUND: Viral suppression is the desired outcome for children and adolescents with HIV. In this article, data from districts supporting community interventions (implementation districts) were reviewed and compared with data from districts without community interventions (nonimplementation districts) to explore a potential correlation between community interventions and clinical outcomes. SETTING: The study was based on data collected from facilities in 6 districts in Lesotho. METHODS: Twelve-month retention, viral load coverage, and viral suppression data from patients with ART between ages 5 and 24 from facilities in both district types were collected retrospectively. RESULTS: Implementation districts showed retention rates of 75%, with 5365 patients (47% of all patients on ART) having documented viral load results and 4641 (87%) being virally suppressed. Retention comparison demonstrated significantly higher rates in implementation districts (73%) as compared to (63%) in nonimplementation districts (P = 0.023). Viral load coverage and suppression comparison found that implementation district hospitals reported 632 (37% of total on ART) patients with a documented viral load, with 539 (85%) virally suppressed, whereas nonimplementation district hospitals reported 220 (31%) patients with viral load results, of whom 181 (82%) were suppressed. CONCLUSIONS: Overall, retention rates in the implementation districts were reasonable and were significantly better than the rates in the nonimplementation districts.

The Gama Cuulu radio serial drama is written and produced in Zambia's Southern Province. It promotes behavior change and service use to prevent HIV transmission. The authors evaluated the effects of Gama Cuulu on intermediate outcomes (e.g., perceived norms), as well as number of sexual partners, condom use, and HIV testing in the past year among adults between 18 and 49 years of age. The authors used a pretest/posttest assessment with a comparison group design, with Southern Province as the intervention area and Western Province as the comparison area. Approximately 1,500 in-person interviews were conducted in both provinces in 2006 (pretest), 2007, and 2008. Regression models included terms for province, time, and the interaction of the two. Outcomes improved in both provinces (e.g., by 2008, 37.6% of participants in Southern Province and 28.3% participants in Western Province tested for HIV in the past year). Pretest-to-posttest changes in condom use (from 20.2% to 29.4% in Southern Province) and 5 intermediate outcomes were significantly different in the 2 provinces. However, changes in condom use were not associated with listening to Gama Cuulu and changes in other outcomes were similar in both provinces. Weak intervention effects might be attributable to implementation challenges or the saturation of HIV programs in Zambia.
