Factors associated with the take-up of voluntary medical male circumcision amongst learners in rural KwaZulu-Natal.

Voluntary medical male circumcision (VMMC) is an integral part of South Africa's HIV prevention programme. School-going males, in particular, are considered a cost-effective target population. However, ambitious policy targets have not been achieved due to the plateau in demand for VMMC. This study documents the factors influencing demand for VMMC amongst school-going males. Data were collected from 750 learners (251 circumcised and 499 uncircumcised) from 42 secondary schools in KwaZulu-Natal, South Africa. There was a positive association between the perceived benefit of VMMC and the likelihood of undergoing circumcision (AOR: 1.41, p = 0.01). There was a negative association between self-efficacy to use condoms and likelihood of undergoing VMMC (AOR: 0.75, p < 0.01). Learners who perceived VMMC as having a number of health benefits, including reducting of the chances of contracting HIV and sexually transmitted infections (STIs), increasing penile hygiene and the belief that VMMC allows them to use condoms less frequently, were more likely to undergo VMMC. Of concern, learners who were confident in their ability to access condoms and t use a condom with their partner were less likely to undergo VMMC.

Early Resumption of Sex following Voluntary Medical Male Circumcision amongst School-Going Males.

Voluntary medical male circumcision is an integral part of the South African government's response to the HIV and AIDS epidemic. Following circumcision, it is recommended that patients abstain from sexual activity for six weeks, as sex may increase the risk of female-to-male HIV transmission and prolong the healing period. This paper investigates the resumption of sexual activity during the healing period among a cohort of school-going males in the KwaZulu-Natal province of South Africa. The analysis for this paper compares two groups of sexually active school-going males: the first group reported having sex during the healing period (n = 40) and the second group (n = 98) reported no sex during the healing period (mean age: 17.7, SD: 1.7).The results show that 29% (n = 40) of young males (mean age: 17.9, SD: 1.8) who were previously sexually active, resumed sexual activity during the healing period, had on average two partners and used condoms inconsistently. In addition, those males that engage in sexual activity during the healing period were less inclined to practice safe sex in the future (AOR = 0.055, p = 0.002) than the group of males who reported no sex during the healing period. These findings suggest that a significant proportion of young males may currently and in the future, subject themselves to high levels of risk for contracting HIV post circumcision. Education, as part of a VMMC campaign, must emphasize the high risk of HIV transmission for both the males their partners during the healing period.

Young women's life experiences and perceptions of sexual and reproductive health in rural KwaZulu-Natal South Africa.

Women in South Africa bear a disproportionate burden of the HIV epidemic. Female-controlled HIV prevention methods offer promising interventions to reduce this burden but cannot be effectively employed without a better understanding of young women's perceptions of their sexual and reproductive health. This study examines social, environmental and cultural factors contributing to young women's perceptions of, and experiences with, sexual and reproductive health to identify the challenges of engaging adolescent girls in HIV prevention. Twenty-five 15-19-year-old women were interviewed using semi-structured in-depth interview questions to discover their life context, future goals and relationships with men, and to understand how these factors influence their sexual and reproductive health decisions and outcomes. A thematic analysis of interview findings indicates that although participants are aware of the risks posed by engaging in risky sexual behaviour, life context shapes their perceptions and prioritisation of their health, which presents a barrier to achieving healthy behaviours and positive health outcomes. These findings may influence future research into how young women's health perceptions influence their sexual health behaviours, and how they utilise sexual and reproductive health services in a clinical setting. This has implications for introducing forms of female-controlled HIV prevention for this population.

Passive Suicidal Ideation and Community Mental Health Resources in South Africa.

South African communities continue to experience elevated incidence and prevalence of HIV infection. Passive suicidal ideation (PSI) may be one expression of distress in high prevalence communities. We report the prevalence of PSI and examine the relationship between PSI and participation in community organizations in a semi-rural sample of South African adults (N = 594). The prevalence of PSI in the 2 weeks prior to the interview was 9.1 %. Members of burial societies (Χ (2) = 7.34; p = 0.01) and stokvels (Χ (2) = 4.1; p = 0.04) (community-based savings groups) reported significantly less PSI compared to other respondents. Using a multivariate model adjusted for demographic characteristics, psychological distress, and socioeconomic status, we found lower odds of reporting PSI for members of burial societies (OR 0.48, CI 0.25 -0.91). Participation in community organizations that provide contextually salient resources in settings with high levels of distress may be a resource for mental health.

High Burden of Human Papillomavirus (HPV) Infection among Young Women in KwaZulu-Natal, South Africa.

OBJECTIVES: HPV infection causes cervical cancer, yet information on prevalence and risk factors for HPV in Africa remain sparse. This study describes the prevalence of HPV genotypes and risk factors associated with HPV among young women ≤ 30 years of age in KwaZulu-Natal (KZN), South Africa. METHODS: Cervicovaginal lavage samples were tested for HPV genotypes in 224 women enrolled in a prospective cohort study. Clinical, behavioural and demographic data were collected. We measured prevalence of HPV genotypes and using logistic regression, examined for factors associated with HPV. RESULTS: Median age of participants was 21 years [interquartile range (IQR):18-23]. The overall prevalence of HPV was 76.3% (171/224) with multiple and single genotypes prevalent in 56.3% and 20.1% of women respectively. Proportion of women with high-risk genotypes (16, 18, 31, 33, 35, 39, 45, 51, 52, 56 and 58) was 54.5%. Women not living with their partner [adjusted odds ratio (aOR)] = 3.42 95% CI1.22-9.60; p = 0.019), was significantly associated with HPV infection and high-risk HPV genotype infection. CONCLUSION: The high burden of HPV and associated risk behaviours highlight the need to intensify behavioural interventions to prevent HPV acquisition in young women. The large scale delivery of HPV vaccine should be prioritised to prevent HPV acquisition and reduce HPV-related morbidity.

Strengthening HIV surveillance in the antiretroviral therapy era: rationale and design of a longitudinal study to monitor HIV prevalence and incidence in the uMgungundlovu District, KwaZulu-Natal, South Africa.

BACKGROUND: South Africa has over 6,000,000 HIV infected individuals and the province of KwaZulu-Natal (KZN) is the most severely affected. As public health initiatives to better control the HIV epidemic are implemented, timely, detailed and robust surveillance data are needed to monitor, evaluate and inform the programmatic interventions and policies over time. We describe the rationale and design of the HIV Incidence Provincial Surveillance System (HIPSS) to monitor HIV prevalence and incidence. METHODS/DESIGN: The household-based survey will include a sample of men and women from two sub-districts of the uMgungundlovu municipality (Vulindlela and the Greater Edendale) of KZN, South Africa. The study is designed as two sequential cross-sectional surveys of 10,000 randomly selected individuals aged 15-49 years to be conducted one year apart. From the cross sectional surveys, two sequential cohorts of HIV negative individuals aged 15-35 years will be followed-up one year later to measure the primary outcome of HIV incidence. Secondary outcomes include the laboratory measurements for pulmonary tuberculosis, sexually transmitted infections and evaluating tests for estimating population-level HIV incidence. Antiretroviral therapy (ART) access, HIV-1 RNA viral load, and CD4 cell counts in HIV positive individuals will assess the effectiveness of the HIV treatment cascade. Household and individual-level socio-demographic characteristics, exposure to HIV programmatic interventions and risk behaviours will be assessed as predictors of HIV incidence. The incidence rate ratio of the two cohorts will be calculated to quantify the change in HIV incidence between consecutive samples. In anticipation of better availability of population-level HIV prevention and treatment programmes leading to decreases in HIV incidence, the sample size provides 84% power to detect a reduction of 30% in the HIV incidence rate between surveys. DISCUSSION: The results from HIPSS will provide critical data regarding HIV prevalence and incidence in this community and will establish whether HIV prevention and treatment efforts in a "real world", non-trial setting have an impact on HIV incidence at a population level. Importantly, the study design and methods will inform future methods for HIV surveillance.

Challenges with participant reimbursement: experiences from a post-trial access study.

Reimbursement of trial participants remains a frequently debated issue, with specific guidance lacking. Trials combining post-trial access and implementation science may necessitate new strategies and models. CAPRISA 008, a post-trial access study testing the feasibility of using family planning services to rollout a prelicensure HIV prevention intervention, tried to balance the real-life scenario of no reimbursement for attendance at public sector clinics with that of a trial including some visits that focused on research procedures and others that focused on standard of care procedures. A reduced reimbursement was offered for 'standard of care' visits, meant primarily to cover transport costs to and from the clinic only. This impacted negatively on accrual, retention and participant morale, primarily due to the protracted delay in regulatory approval, during which time, the costs of living, including travel costs had increased. Relevant guidelines were reviewed and institutional policy was updated to incorporate the South African National Health Research Ethics Committee guidelines on reimbursement (taking into account participant time, travel and inconvenience). The reimbursement amount for 'standard of care' visits was increased accordingly. The question remains whether a trial that combines post-trial access with implementation science, with clear benefits for the participants and the provision of above standard medical care, should have reimbursement rates that approach those of a proof-of-concept trial, for 'standard of care' visits.

Evaluating community engagement in global health research: the need for metrics.

BACKGROUND: Community engagement in research has gained momentum as an approach to improving research, to helping ensure that community concerns are taken into account, and to informing ethical decision-making when research is conducted in contexts of vulnerability. However, guidelines and scholarship regarding community engagement are arguably unsettled, making it difficult to implement and evaluate. DISCUSSION: We describe normative guidelines on community engagement that have been offered by national and international bodies in the context of HIV-related research, which set the stage for similar work in other health related research. Next, we review the scholarly literature regarding community engagement, outlining the diverse ethical goals ascribed to it. We then discuss practical guidelines that have been issued regarding community engagement. There is a lack of consensus regarding the ethical goals and approaches for community engagement, and an associated lack of indicators and metrics for evaluating success in achieving stated goals. To address these gaps we outline a framework for developing indicators for evaluating the contribution of community engagement to ethical goals in health research. There is a critical need to enhance efforts in evaluating community engagement to ensure that the work on the ground reflects the intentions expressed in the guidelines, and to investigate the contribution of specific community engagement practices for making research responsive to community needs and concerns. Evaluation mechanisms should be built into community engagement practices to guide best practices in community engagement and their replication across diverse health research settings.

Trends in HIV Prevalence in Pregnant Women in Rural South Africa.

BACKGROUND: Despite substantial progress in the delivery of HIV prevention programs, some communities continue to experience high rates of HIV infection. We report on temporal trends in HIV prevalence in pregnant women in a community in rural KwaZulu-Natal in South Africa. METHODS: Annual, anonymous cross-sectional HIV sero-prevalence surveys were conducted between 2001 and 2013 among first visit prenatal clinic attendees. The time periods 2001 to 2003 were defined as pre-antiretroviral therapy (ART), 2004 to 2008 as early ART, and 2009 to 2013 as contemporary ART roll-out, to correspond with the substantial scale-up of ART program. RESULTS: Overall, HIV prevalence rose from 35.3% [95% confidence interval (CI): 32.3 to 38.3] pre-ART (2001-2003) to 39.0% (95% CI: 36.8 to 41.1) in the early ART (2004-2008) to 39.3% (95% CI: 37.2 to 41.4) in the contemporary ART (2009-2013) roll-out periods. In teenage women (<20 years), HIV prevalence declined from 22.5% (95% CI: 17.5 to 27.5) to 20.7% (95% CI: 17.5 to 23.8) and to 17.2% (95% CI: 14.3 to 20.2) over the similar ART roll-out periods (P = 0.046). Prevalence increased significantly in women 30 years and older (P < 0.001) over the same time period largely because of survival after ART scale up. Teenage girls with male partners of age 20-24 and ≥ 25 years had a 1.7-fold (95% CI: 1.3-2.4; P = 0.001) and 3-fold (95% CI: 2.1 to 4.3; P < 0.001) higher HIV prevalence respectively. CONCLUSIONS: Notwithstanding the encouraging decline in teenagers, the ongoing high HIV prevalence in pregnant women in this rural community, despite prevention and treatment programs, is deeply concerning. Targeted interventions for teenagers, especially for those in age-disparate relationships, are needed to impact this HIV epidemic trajectory.

HIV-positive status disclosure in patients in care in rural South Africa: implications for scaling up treatment and prevention interventions.

A nuanced understanding of HIV-positive status disclosure is urgently needed to inform the implementation of prevention interventions, including TasP and PrEP. To provide such understanding for the high HIV-burden setting of rural KwaZulu-Natal, we conducted a prospective cohort study to characterize determinants and trends in HIV-positive status disclosure. 687 consenting HIV-positive individuals (73.2 % female; 60.3 % ART initiated) were enrolled. Reports of any incidence of disclosure to either a family member or sexual partner at enrollment and follow-up visits (median 4.4 months post-enrolment) were common (91.0 %); however, reports of disclosure specifically to sexual partners were relatively rare (34.1 %), especially in women (29.8 %). Participants not engaged in a stable partnerships, not ART-imitated, and/or who had disclosed to their family were at risk of non-disclosure to sexual partners. These data highlight both an urgent need to empower HIV-positive individuals, and the significant barriers to targeting sero-discordant couples for HIV prevention in this setting.

Assessing the implementation effectiveness and safety of 1% tenofovir gel provision through family planning services in KwaZulu-Natal, South Africa: study protocol for an open-label randomized controlled trial.

BACKGROUND: The Centre for the AIDS Programme of Research in South Africa (CAPRISA) 004 trial demonstrated a 39% reduction in HIV infection, with a 54% HIV reduction in women who used tenofovir gel consistently. A confirmatory trial is expected to report results in early 2015. In the interim, we have a unique window of opportunity to prepare for and devise effective strategies for the future policy and programmatic scale-up of tenofovir gel provision. One approach is to integrate tenofovir gel provision into family planning (FP) services. The CAPRISA 008 implementation trial provides an opportunity to provide post-trial access to tenofovir gel while generating empiric evidence to assess whether integrating tenofovir gel provision into routine FP services can achieve similar levels of adherence as the CAPRISA 004 trial. METHODS/DESIGN: This is a two-arm, open-label, randomized controlled non-inferiority trial. A maximum of 700 sexually active, HIV-uninfected women aged 18 years and older who previously participated in an antiretroviral prevention study will be enrolled from an urban and rural site in KwaZulu-Natal, South Africa. The anticipated study duration is 30 months, with active accrual requiring approximately 12 months (following which an open cohort will be maintained) and follow-up continuing for approximately 18 months. At each of the two sites, eligible participants will be randomly assigned to receive tenofovir gel through either FP services (intervention arm) or through the CAPRISA research clinics (control arm). As part of the study intervention, a quality improvement approach will be used to assist the FP services to expand their current services to include tenofovir gel provision. DISCUSSION: This protocol aims to address an important implementation question on whether FP services are able to effectively incorporate tenofovir gel provision for this at-risk group of women in South Africa. Provision of tenofovir gel to the women from the CAPRISA 004 trial meets the ethical obligation for post-trial access, and helps identify a potential avenue for future scale-up of microbicides within the public health system of South Africa. TRIAL REGISTRATION: This trial was registered with the South Africa Department of Health (reference: DOH-27-0812-4129) and ClinicalTrials.gov (reference: NCT01691768) on 05 July 2012.

Meeting the sexual and reproductive health needs of high-school students in South Africa: experiences from rural KwaZulu-Natal.

BACKGROUND: Adolescents in South Africa (SA) have a huge unmet need for sexual and reproductive health (SRH) services. Integrating such services into schools may overcome many of the current barriers to access. OBJECTIVES: We describe an SRH service model developed for high-school students and its implementation in 14 high schools in rural SA. METHODS: Following consultation with community and other key stakeholders about the demand for and acceptability of adolescent-targeted SRH services, a three-tier school-based model was developed that included: (i) in-school group SRH information and awareness sessions; (ii) in-school individual SRH counselling and customised HIV counselling and testing (CCT); and (iii) referrals to in-school fixed, in-school mobile or public sector primary SRH clinics. RESULTS: From October 2011 to June 2012, 70 consultative meetings were held. There was overwhelming support for the pilot founded on concerns about the high HIV prevalence and teenage pregnancy rates among adolescents in the community. SRH information was provided to 8 867 high-school students, 4 171 (47.0%) of whom accessed on-site CCT services for HIV. The gender-specific prevalence of HIV in these students was 3.3% (64/1 962) and 1.1% (24/2 209) for females and males, respectively. Two hundred and thirty-nine students (5.7%) were referred for clinical services at in-school fixed, in-school mobile or public sector primary SRH clinics. CONCLUSIONS: The SRH service provision pilot was acceptable in the community and seems feasible for scale-up. Further work is required to understand inter-school variability in uptake, identify additional service needs of students, and characterise SRH demand dynamics.

Barriers and facilitators to the uptake of voluntary medical male circumcision (VMMC) among adolescent boys in KwaZulu-Natal, South Africa.

Epidemiological modelling has concluded that if voluntary medical male circumcision (VMMC) is scaled up in high HIV prevalence settings it would lead to a significant reduction in HIV incidence rates. Following the adoption of this evidence by the WHO, South Africa has embarked on an ambitious VMMC programme. However, South Africa still falls short of meeting VMMC targets, particularly in KwaZulu-Natal, the epicentre of the HIV/AIDS epidemic. A qualitative study was conducted in a high HIV prevalence district in KwaZulu-Natal to identify barriers and facilitators to the uptake of VMMC amongst adolescent boys. Focus group discussions with both circumcised and uncircumcised boys were conducted in 2012 and 2013. Analysis of the data was done using the framework approach and was guided by the Social Cognitive Theory focussing on both individual and interpersonal factors influencing VMMC uptake. Individual cognitive factors facilitating uptake included the belief that VMMC reduced the risk of HIV infection, led to better hygiene and improvement in sexual desirability and performance. Cognitive barriers related to the fear of HIV testing (and the subsequent result and stigmas), which preceded VMMC. Further barriers related to the pain associated with the procedure and adverse events. The need to abstain from sex during the six-week healing period was a further prohibiting factor for boys. Timing was crucial, as boys were reluctant to get circumcised when involved in sporting activities and during exam periods. Targeting adolescents for VMMC is successful when coupled with the correct messaging. Service providers need to take heed that demand creation activities need to focus on the benefits of VMMC for HIV risk reduction, as well as other non-HIV benefits. Timing of VMMC interventions needs to be considered when targeting school-going boys.

HIV infection in high school students in rural South Africa: role of transmissions among students.

In South Africa, adolescents constitute a key population at high risk of HIV acquisition. However, little is known about HIV transmission among students within schools. This study was undertaken to assess the risk factors for HIV infection and the extent of transmission among rural high school students. Between February and May 2012, consenting students from five randomly selected public sector high schools in rural KwaZulu-Natal participated in an anonymous cross-sectional survey. Dried blood spot samples were collected and tested for HIV. ß-Human chorionic gonadotropin (ßHCG) levels were measured in females for pregnancy. Family circumstances as well as sociodemographic and behavioral factors were assessed as potential risk factors. A subset (106/148, 72%) of HIV-positive samples underwent gag p17p24 sequencing for phylogenetic analysis. A total of 3,242 students (81.7% of enrolled students) participated. HIV prevalence was 6.8% [95% confidence interval (CI) 3.9-9.8%] in girls and 2.7% (CI 1.6-3.8%) in boys [adjusted odds ratio (aOR)=3.0, CI 2.4-3.8; p<0.001]. HIV prevalence increased from 4.6% (95% CI 1.9-7.3) in the 12- to 15-year-old girls to 23.1% (95% CI 7.7-38.5) in girls over 20 years, while in boys HIV prevalence increased from 2.7% (95% CI 0.6-4.9) in the 12- to15-year-old boys to 11.1% (95% CI 2.7-19.4) in those over 20 years. Sequencing of samples obtained from students revealed only two clusters, suggesting within-school transmission and three interschool clusters, while the remainder was most likely acquired from sources other than those currently found in students attending the school concerned. HIV prevalence in both girls (aOR=3.6, CI 2.9-4.5; p<0.001) and boys (aOR=2.8, CI 1.2-6.2; p=0.01) was higher in those without a living biological mother. The high burden of HIV infection among students was not associated with intraschool transmission in this rural setting. Lack of a living parent is an important factor defining high risk in this group of adolescents.

Prevalence of HIV, HSV-2 and pregnancy among high school students in rural KwaZulu-Natal, South Africa: a bio-behavioural cross-sectional survey.

OBJECTIVE: Adolescents in southern African high schools are a key population for HIV prevention interventions. We report on the prevalence of HIV, HSV-2 and pregnancy as indicators of high-risk sexual behaviour among high school students in rural KwaZulu-Natal. DESIGN: Bio-behavioural cross-sectional survey. METHODS: Students completed a self-administered structured, standardised demographic and sexual behavioural questionnaire. Dried blood spot specimens were collected for HIV and HSV-2 testing. Urine specimens were used for pregnancy testing in female students. RESULTS: A total of 2675 (1423 females, 1252 males) consenting students were enrolled from 14 high schools between September and November 2010. The median age of students was 16 years (IQR 15-18). HIV prevalence was 1.4% (95% CI 0.9 to 1.9) in males and 6.4% (95% CI 4.6 to 8.3) in females (p<0.001). HSV-2 prevalence was 2.6% (95% CI 1.6 to 3.7) in males and 10.7% (95% CI 8.8 to 12.6) in females (p<0.001). Pregnancy prevalence was 3.6% (95% CI 2.6 to 4.5). Risk factors for prevalent HIV infection in female students included being over 18 years of age (adjusted OR (aOR)=2.67, 95% CI 1.67 to 4.27; p<0.001), prevalent HSV-2 infection (aOR=4.35, 95% CI 2.61 to 7.24; p<0.001), previous pregnancy (aOR=1.66, 95% CI 1.10 to 2.51; p=0.016) and experience of two or more deaths in the household in the previous year (aOR=1.97, 95% CI 1.13 to 3.44; p=0.016). CONCLUSIONS: The high prevalence of HIV, HSV-2 and pregnancy underscore the need for school-based sexual and reproductive health services, and provide further impetus for the inclusion of adolescents in behavioural and biomedical trials with HIV incidence endpoints.

Implementation of adolescent-friendly voluntary medical male circumcision using a school based recruitment program in rural KwaZulu-Natal, South Africa.

BACKGROUND: Epidemiological data from South Africa demonstrate that risk of human immunodeficiency virus (HIV) infection in males increases dramatically after adolescence. Targeting adolescent HIV-negative males may be an efficient and cost-effective means of maximising the established HIV prevention benefits of voluntary medical male circumcision (VMMC) in high HIV prevalence-, low circumcision practice-settings. This study assessed the feasibility of recruiting male high school students for VMMC in such a setting in rural KwaZulu-Natal. METHODS AND FINDINGS: Following community and key stakeholder consultations on the acceptability of VMMC recruitment through schools, information and awareness raising sessions were held in 42 high schools in Vulindlela. A three-phase VMMC demand-creation strategy was implemented in partnership with a local non-governmental organization, ZimnadiZonke, that involved: (i) community consultation and engagement; (ii) in-school VMMC awareness sessions and centralized HIV counselling and testing (HCT) service access; and (iii) peer recruitment and decentralized HCT service access. Transport was provided for volunteers to the Centre for the AIDS Programme of Research in South Africa (CAPRISA) clinic where the forceps-guided VMMC procedure was performed on consenting HIV-negative males. HIV infected volunteers were referred to further care either at the CAPRISA clinic or at public sector clinics. Between March 2011 and February 2013, a total of 5165 circumcisions were performed, the majority (71%) in males aged between 15 and 19 years. Demand-creation strategies were associated with an over five-fold increase in VMMC uptake from an average of 58 procedures/month in initial community engagement phases, to an average of 308 procedures/month on initiation of the peer recruitment-decentralized service phase. Post-operative adverse events were rare (1.2%), mostly minor and self-resolving. CONCLUSIONS: Optimizing a high volume, adolescent-targeted VMMC program was feasible, acceptable and safe in this setting. Adaptive demand-creation strategies are required to sustain high uptake.

Disclosure of microbicide gel use to sexual partners: influence on adherence in the CAPRISA 004 trial.

Young women in sub-Saharan Africa are disproportionately affected by HIV, making the development of women initiated and controlled methods of prevention, including microbicides, a priority. Adherence is pivotal to microbicide efficacy and partner related factors are known to impact adherence. An analysis of disclosure of gel use to sexual partners and adherence in CAPRISA 004 women was conducted to better understand this relationship. Partner disclosure was significantly associated with a modest 4.2 % increased adherence (71.0 vs. 66.8 %, p = 0.03). Most women rated the experience of disclosure as positive, despite 6.7 % of partners expressing a negative reaction.Participants who disclosed were more likely to reside with their regular partner (14.4 vs. 8.4 %; p = 0.01) and reported consistent condom use at baseline (32.9 vs. 20.9 %; p < 0.01). Partner disclosure needs to be better understood as a potential facilitator or barrier to microbicide adherence.

High rates of tuberculosis in patients accessing HAART in rural South Africa.

BACKGROUND: The challenge of early tuberculosis (TB) infection among rural patients accessing highly active antiretroviral therapy (HAART) in a resource-limited setting with high HIV and TB burden has not been fully quantified. METHODS: This is a retrospective study nested within a prospective study of 969 patients consecutively initiated onto HAART at the CAPRISA AIDS Treatment programme in rural KwaZulu-Natal between January 2007 and December 2010. Patients were screened for clinical symptoms consistent with TB using a standardized checklist, and routine clinical investigations that included sputum microscopy and chest x-ray diagnosis. RESULTS: Of 969 HIV-infected patients initiated on HAART, 173 [17.9%; 95% confidence interval (CI): 15.5 to 20.4] had active TB at HAART initiation. TB incidence rates were 3-fold higher in the first 3 months (early incident TB) after HAART initiation [11.5/100 person-years (py); 95% CI: 7.1 to 17.5] compared with 4-24 months (late incident TB) post-HAART initiation (3.2/100 py; 95% CI: 2.2 to 4.5; incidence rate ratio: 3.6; 95% CI: 2.0 to 6.4; P < 0.001). Immune status of patients at HAART initiation did not impact TB incidence rates in patients with CD4 counts of <50 (5.3/100) and >200 (4.9/100 py; P = 0.81) cells per cubic millimeter. CD4 count gains achieved 12 months post-HAART initiation were significantly different in patients with early incident TB versus late incident TB; P = 0.03. CONCLUSIONS: Rural HIV treatment programmes in TB-endemic settings experience high rates of TB irrespective of immunologic status of patients at HAART initiation, or duration on HAART.

Barriers and Facilitators to the Uptake of Voluntary Medical Male Circumcision (VMMC) among Adolescent Boys in KwaZulu-Natal; South Africa

HIV prevalence among high school learners - opportunities for school-based HIV testing programmes and sexual reproductive health services.

BACKGROUND: Young girls in sub Saharan Africa are reported to have higher rates of human immunodeficiency virus (HIV) infection compared to boys in the same age group. Knowledge of HIV status amongst high schools learners provides an important gateway to prevention and treatment services. This study aimed at determining the HIV prevalence and explored the feasibility of HIV testing among high school learners. METHODS: Between September 2010 and February 2011, a linked, anonymous cross-sectional survey was conducted in two public sector high schools in the rural KwaZulu-Natal midlands. Following written informed consent, dried blood spot samples (DBS) were collected and tested for HIV. The overall and age-specific HIV prevalence were compared with select demographic variables. RESULTS: The HIV prevalence in learners aged 12 to 25 in school A was 4.7% (95% CI 2.8-6.5) compared to 2.5% (95% CI 1.6-3.5) in school B, (p=0.04). Whilst the HIV prevalence was similar for boys at 1.3% (95% CI 0-2.8) in school A and 1.7% (95% CI 0.5-2.8) in school B, the prevalence in girls was consistently higher and was 7.7% (95% CI 4.5-10.9) in school A and 3.2% (95% CI 1.8-4.6) in school B. The age-specific HIV prevalence in girls increased 1.5 to 2 fold for each two year age category, while for boys the prevalence was stable across all age groups. CONCLUSIONS: The high HIV prevalence in female learners underscores the importance of sexual reproductive health and schools-based HIV testing programs as an important gateway to prevention and treatment services.
