Objectives The aim of the study was to estimate rates of linkage to HIV care and antiretroviral treatment (ART) initiation after the introduction of home‐based HIV counselling and testing (HBHCT) and telephone‐facilitated support for linkage in rural South Africa. Methods A population‐based prospective cohort study was carried out in KwaZulu Natal, South Africa. All residents aged ≥ 15 years were eligible for HBHCT. Those who tested positive and were not in care were referred for ART at one of 11 public‐sector clinics. Individuals who did not attend the clinic within 2 weeks were sent a short message service (SMS) reminder; those who had not attended after a further 2 weeks were telephoned by a nurse counsellor, to discuss concerns and encourage linkage. Kaplan–Meier methods were used to estimate the proportion of newly diagnosed individuals linking to care and initiating ART. Results Among 38 827 individuals visited, 26% accepted HBHCT. Uptake was higher in women than in men (30% versus 20%, respectively), but similar in people aged < 30 years and ≥ 30 years (28% versus 26%, respectively). A total of 784 (8%) tested HIV positive, of whom 427 (54%) were newly diagnosed. Within 6 months, 31% of women and 18% of men < 30 years old had linked to care, and 29% and 16%, respectively, had started ART. Among those ≥ 30 years, 41% of women and 38% of men had linked to care within 6 months, and 41% and 35%, respectively, had started ART. Conclusions Despite facilitated linkage, rates of timely linkage to care and ART initiation after HBHCT were very low, particularly among young men. Innovations are needed to provide effective HIV care and prevention interventions to young people, and thus maximize the benefits of universal test and treat.

We used a randomised, double-blind, crossover design to evaluate the pharmacokinetics, safety and tolerability of three doses of buccal adhesive testosterone tablets (BATT). Twenty-four healthy men, whose endogenous testosterone was suppressed to c5·38 nmol/l with leuprorelin acetate, took BATT (10, 20 or 30 mg) daily for 10 days. There was a 4-day washout between treatments. Substantial testosterone absorption occurred from BATT, and mean serum testosterone, free testosterone and dihydrotestosterone (DHT) concentrations over 24 h showed circadian variation. Steady state was reached by day 5. Average 24-h concentrations for the three BATT doses were within the normal range for eugonadal men: testosterone 11·67-14·57 nmol/l, free testosterone 0·026-0·33 nmol/l and DHT 1·66-2·03 nmol/l. On all three doses, peak testosterone and free testosterone was reached 8-9 h after tablet application; DHT peaked about 1-2 h later, and declined more slowly. Hormone concentrations increased with BATT dose, but increases were less than dose-proportional. There was no evidence of testosterone accumulation. BATT was well tolerated.
