SummaryBackground-Across many observational studies, herpes simplex virus type 2 (HSV-2) infection is associated with two-fold to three-fold increased risk for HIV-1 infection. We investigated whether HSV-2 suppression with aciclovir would reduce the risk of HIV-1 acquisition.

BackgroundThere is limited evidence that interventions for depression and other common mental disorders (CMD) can be integrated sustainably into primary health care in Africa. We aimed to pilot a low-cost multi-component 'Friendship Bench Intervention' for CMD, locally adapted from problem-solving therapy and delivered by trained and supervised female lay workers to learn if was feasible and possibly effective as well as how best to implement it on a larger scale.MethodWe trained lay workers for 8 days in screening and monitoring CMD and in delivering the intervention. Ten lay workers screened consecutive adult attenders who either were referred or self-referred to the Friendship Bench between July and December 2007. Those scoring above the validated cut-point of the Shona Symptom Questionnaire (SSQ) for CMD were potentially eligible. Exclusions were suicide risk or very severe depression. All others were offered 6 sessions of problem-solving therapy (PST) enhanced with a component of activity scheduling. Weekly nurse-led group supervision and monthly supervision from a mental health specialist were provided. Data on SSQ scores at 6 weeks after entering the study were collected by an independent research nurse. Lay workers completed a brief evaluation on their experiences of delivering the intervention.ResultsOf 395 potentially eligible, 33 (8%) were excluded due to high risk. Of the 362 left, 2% (7) declined and 10% (35) were lost to follow-up leaving an 88% response rate (n = 320). Over half (n = 166, 52%) had presented with an HIV-related problem. Mean SSQ score fell from 11.3 (sd 1.4) before treatment to 6.5 (sd 2.4) after 3-6 sessions. The drop in SSQ scores was proportional to the number of sessions attended. Nine of the ten lay workers rated themselves as very able to deliver the PST intervention.ConclusionWe have found preliminary evidence of a clinically meaningful improvement in CMD associated with locally adapted problem-solving therapy delivered by lay health workers through routine primary health care in an African setting. There is a need to test the effectiveness of this task-shifting mental health intervention in an appropriately powered randomised controlled trial.Trial registrationISRCTN: ISRCTN25476759

Background HIV prevention among young people in southern Africa is a public health priority. There is little rigorous evidence of the effectiveness of different intervention approaches. We describe findings of a cluster randomised trial of a community-based, multi-component HIV and reproductive health intervention aimed at changing social norms for adolescents in rural Zimbabwe. Methods Thirty rural communities were randomised to early or deferred implementation of the intervention in 2003. Impact was assessed in a representative survey of 18–22 year olds after 4 years. Participants self-completed a questionnaire and gave a dried blood spot sample for HIV and HSV-2 antibody testing. Young women had a urinary pregnancy test. Analyses were by intention-to-treat and were adjusted for clustering. Findings 4,684 18–22 year olds participated in the survey (97.1% of eligibles, 55.5% female). Just over 40% had been exposed to ≥ 10 intervention sessions. There were modest improvements in knowledge and attitudes among young men and women in intervention communities, but no impact on self-reported sexual behaviour. There was no impact of the intervention on prevalence of HIV or HSV-2 or current pregnancy. Women in intervention communities were less likely to report ever having been pregnancy. Interpretation Despite an impact on knowledge, some attitudes and on reported pregnancy, there was no impact of this intervention on HIV or HSV-2 prevalence, further evidence that behavioural interventions alone are unlikely to be sufficient to reverse the HIV epidemic. The challenge remains to find effective HIV prevention approaches for young people in the face of continued and unacceptably high HIV incidence, particularly among young women.

IntroductionAdolescence is a time of physical, emotional and social transitions that have implications for health. In addition to being at high risk for HIV, young key populations (YKP) may experience other health problems attributable to high-risk behaviour or their developmental stage, or a combination of both.DiscussionWe reviewed the needs, barriers and gaps for other non-HIV health services for YKP. We searched PubMed and Google Scholar for articles that provided specific age-related data on sexual and reproductive health; mental health; violence; and substance use problems for adolescent, youth or young sex workers, men who have sex with men, transgender people, and people who inject drugs.ResultsYKP experience more unprotected sex, sexually transmitted infections including HIV, unintended pregnancy, violence, mental health disorders and substance use compared to older members of key populations and youth among the general population. YKP experience significant barriers to accessing care; coverage of services is low, largely because of stigma and discrimination experienced at both the health system and policy levels.DiscussionYKP require comprehensive, integrated services that respond to their specific developmental needs, including health, educational and social services within the context of a human rights-based approach. The recent WHO Consolidated Guidelines on HIV Prevention, Diagnosis, Treatment and Care for Key Populations are an important first step for a more comprehensive approach to HIV programming for YKP, but there are limited data on the effective delivery of combined interventions for YKP. Significant investments in research and implementation will be required to ensure adequate provision and coverage of services for YKP. In addition, greater commitments to harm reduction and rights-based approaches are needed to address structural barriers to access to care.

Objective-An AIDS epidemic among older children and adolescents is clinically apparent in Southern Africa. We estimated the likely scale and time course of the epidemic in older survivors of vertical HIV infection.Design-We modelled demographic, HIV prevalence, mother-to-child transmission (MTCT) and child survival data to project HIV burden among older children in two Southern African countries at different stages of severe HIV epidemics. Using measured survival data for children, we estimate that 64% of HIV-infected infants are fast-progressors with median survival=0.64 years and 36% are slow-progressors with median survival=16.0 years. We confirmed model validity by comparing model predictions to available epidemiological data.

Background Adolescents living with HIV face challenges to their wellbeing and antiretroviral therapy adherence and have poor treatment outcomes. We aimed to evaluate a peer-led differentiated service delivery intervention on HIV clinical and psychosocial outcomes among adolescents with HIV in Zimbabwe. Methods 16 public primary care facilities (clusters) in two rural districts in Zimbabwe (Bindura and Shamva) were randomly assigned (1:1) to provide enhanced HIV care support (the Zvandiri intervention group) or standard HIV care (the control group) to adolescents (aged 13-19 years) with HIV. Eligible clinics had at least 20 adolescents in pre-ART or ART registers and were geographically separated by at least 10 km to minimise contamination. Adolescents were eligible for inclusion if they were living with HIV, registered for HIV care at one of the trial clinics, and either starting or already on ART. Exclusion criteria were being too physically unwell to attend clinic (bedridden), psychotic, or unable to give informed assent or consent. Adolescents with HIV at all clinics received adherence support through adult counsellors. At intervention clinics, adolescents with HIV were assigned a community adolescent treatment supporter, attended a monthly support group, and received text messages, calls, home visits, and clinic-based counselling. Implementation intensity was differentiated according to each adolescent's HIV vulnerability, which was reassessed every 3 months. Caregivers were invited to a support group. The primary outcome was the proportion of adolescents who had died or had a viral load of at least 1000 copies per μL after 96 weeks. In-depth qualitative data were collected and analysed thematically. The trial is registered with Pan African Clinical Trial Registry, number PACTR201609001767322.

Introduction:Although prevention of mother-to-child HIV transmission (PMTCT) programs are widely implemented, many children do not benefit from them because of loss to follow-up (LTFU). We conducted a systematic review to determine the magnitude of infant/baby LTFU along the PMTCT cascade.Methods:Eligible publications reported infant LTFU outcomes from standard care PMTCT programs (not intervention studies) at any stage of the cascade. Literature searches were conducted in Medline, Embase, Web of Knowledge, CINAHL Plus, and Maternity and Infant Care. Extracted data included setting, methods of follow-up, PMTCT regimens, and proportion and timing of LTFU. For programs in sub-Saharan Africa, random-effects meta-analysis was done using Stata v10. Because of heterogeneity, predictive intervals (PrIs; approximate 95% confidence intervals of a future study based on extent of observed heterogeneity) were computed.Results:A total of 826 papers were identified; 25 publications were eligible. Studies were published from 2001 to 2012 and were mostly from sub-Saharan Africa (three were from India, one from UK and one from Ireland). There was extensive heterogeneity in findings. Eight studies reported on LTFU of pregnant HIV-positive women between antenatal care (ANC) registration and delivery, which ranged from 10.9 to 68.1%, pooled proportion 49.08% [95% confidence interval (CI) 39.6–60.9%], and PrI 22.0–100%. Fourteen studies reported LTFU of infants within 3 months of delivery, range 4.8–75%, pooled proportion 33.9% (27.6–41.5), and PrI 15.4–74.2. Children were also lost after HIV testing; this was reported in five studies, pooled estimate 45.5% (35.9–57.6), PrI 18.7–100%. Programs that actively tracked defaulters had better retention outcomes.Conclusion:There is unacceptable infant LTFU from PMTCT programs. Countries should incorporate defaulter-tracking as standard to improve retention.
