Unsuppressed viral load (VL) in patients on antiretroviral therapy (ART) occurs when treatment fails to suppress a person's VL and is associated with decreased survival and increased HIV transmission. The objective of this study was to evaluate factors associated with unsuppressed VL (VL > 400 copies/ml) in patients currently in care on first-line ART for ≥ 6 months attending South African public healthcare facilities. We analysed electronic medical records of ART patients with a VL result on record who started ART between January 2004 and April 2016 from 271 public health facilities. We present descriptive and multivariable logistic regression for unsuppressed VL at last visit using a priori variables. We included 244,370 patients (69% female) on first-line ART in April 2016 for ≥ 6 months. Median age at ART start was 33 years (7% were < 15 years old). Median duration on ART was 3.7 years. Adjusting for other variables, factors associated with having an unsuppressed VL at the most recent visit among patients in care included: (1) < 15 years old at ART start (adjusted odds ratio [aOR]=2.58; 95% CI = 2.37, 2.81) versus 15-49 years at ART start, (2) male gender (aOR = 1.29; 95% CI = 1.25, 1.35), (3) 6-12 months on ART versus longer (aOR = 1.34; 95% CI = 1.29, 1.40), (4) on tuberculosis (TB) treatment (aOR = 1.78; 95% CI = 1.48, 2.13), and (5) prior ART exposure versus none (aOR = 1.20; 95% CI = 1.08, 1.32). Approximately 85% of the ART cohort who were in care had achieved viral suppression, though men, youth/adolescents, patients with prior ART exposure, those with short duration of ART, and patients on TB treatment had increased odds of not achieving viral suppression. There is a need to develop and evaluate targeted interventions for ART patients in care who are at high risk of unsuppressed VL.

Subpopulations of genetically related HIV strains were observed in Italy, France, Scotland and Spain, in contrast to the Netherlands, Austria and Switzerland. This difference between the two groups of countries suggests that the HIV epidemics amongst IDU in the latter group was caused by multiple virus introductions. In Edinburgh and the surrounding area, most IDU were infected with the same GGC strain over the 12-year study period. The epidemic among IDU in north-western Europe started with GGC viruses, whereas in south-western Europe non-GGC viruses predominated. This geographical separation has faded during the course of the epidemic, most likely because of virus exchange among IDU populations.

IntroductionSouth Africa introduced Universal Test and Treat in 2016 including antiretroviral therapy (ART) initiation on the same‐day as HIV diagnosis. Our study sought to evaluate the impact of same‐day ART initiation on loss to follow‐up (LTFU) and mortality comparing with patients who initiated ART after their HIV diagnosis.MethodsWe conducted a file review of patients with a HIV diagnosis and ART start date on file between September 2016 and May 2018 in six high HIV burden districts. Our primary outcome was LTFU (>90 days from the last clinical visit or drug pick‐up until database closure 31 July 2018). The secondary outcome was mortality after ART initiation. Time to outcome was assessed comparing same‐day vs. one to seven, eight to twenty‐one and ≥ twenty‐two days to ART initiation using Kaplan‐Meier estimators stratified by sex. We investigated predictors using univariate and multivariable Cox proportional hazards models, adjusting for a priori characteristics.ResultsOverall, 92,609 ART patients contributed 43,922 person‐years from ART initiation, with a median follow‐up time of 246 days (IQR = 112 to 455). Of these patients, 33,399 (36%) initiated ART on the same‐day as their HIV diagnosis date and had a median follow‐up time of 174 days (IQR = 85 to 349). Same‐day patients were predominantly non‐pregnant females (56%) and aged 25 to 34 years (40%). Same‐day ART initiation increased from 2.8% in September 2016 to 7.1% in April 2018. In same‐day patients, 33% (n = 11,114) were classified as LTFU with a median time of 55 days (IQR = 1 to 185), compared to 371 mean days (IQR = 161 to 560) in patients who initiated ≥22 days after diagnosis. A similar proportion of LTFU was observed for patients who initiated later: 31% 1 to 21 day and 33% ≥22 day. Same‐day ART patients had an increased risk of LTFU vs. ≥1 day (adjusted hazard ratio (aHR) = 1.28, 95% CI = 1.24 to 1.33) adjusting for covariates. Although all‐cause mortality was slightly lower in same‐day patients (0.9%) vs. >1 day (1.4%; aHR = 0.87, 95% CI = 0.72 to 1.05) adjusting for covariates. Men had highest risk of mortality and LTFU.ConclusionsSame‐day ART increased the risk of LTFU, but same‐day patients experienced slightly lower mortality. Same‐day patients may require additional counselling and interventions to improve retention. Additional research is needed on targeted interventions, including differentiated care, to reduce LTFU in patients initiating ART same‐day.

Background There is an imperative need for innovative interventions to identify people living with HIV and initiate them on antiretroviral therapy (ART). The objective of this study was to determine the feasibility of providing index partner/child testing of people living with HIV. Methods We trained 86 nurses and counsellors in 56 public health facilities in six high HIV burden Districts in 2017 to provide index partner/child testing (tracing and testing of partners/children of people living with HIV). We collected programmatic data including index partner/child HIV positivity by age, gender and location of testing. In sub-analyses, we evaluated factors associated with identifying HIV-positive partners and children in separate models using multivariable logistic regression. Results We tested 16,033 partners and children of index patients between October 2017 and June 2018. Most of those tested were female (61%) and 20–39 years old (39%). Overall, 6.4% were 10–14 years old, 9.5% were 15–19 years; 8% were >50 years. HIV positivity was 38% (95% CI=36%−40%). In children ages 10–14, 13% were HIV-infected (95% CI=11%−14%). In subanalyses, HIV positivity in partners was associated with their increased age (adjusted odds ratio [aOR] for increase in 5-year age category=1.21; 95% CI=1.04, 1.42), female gender (aOR=1.38; 95% CI=1.04, 1.82) and bringing the partner in for HIV testing vs. referring the partner through the provider or recommending testing to the partner (aOR=1.94, 95% CI=1.43, 2.63), adjusting for location of testing. Almost all patients diagnosed (97%) were referred to ART. Conclusion Providing index partner/child testing was feasible and we identified a very high yield when testing partners/children of index patients. Index partner/child testing should be offered to all patients living with HIV to improve case finding.
