Objectives: Although youth (12-24 years) in Sub-Saharan Africa have a high HIV risk, many have poor access to HIV testing services and are unaware of their status. Our objective was to evaluate the proportion of adolescents (12-17 years) and young adults (18-24 years) who underwent HIV testing and the prevalence among those tested in an urban adult outpatient clinic with a routine HIV testing program in Durban, South Africa. Design: We conducted a retrospective cross-sectional analysis of adolescent and young adult outpatient records between February 2008 and December 2009. Methods: We determined the number of unique outpatient visitors, HIV tests, and positive rapid tests among those tested. Results: During the study period, 956 adolescents registered in the outpatient clinic, of which 527 (55%) were female. Among adolescents, 260/527 (49%, 95% CI 45-54%) females underwent HIV testing compared to 129/429 (30%, 95% CI 26-35%) males (p<0.01). The HIV prevalence among the 389 (41%, 95% CI 38-44%) adolescents who underwent testing was 16% (95% CI 13-20%) and did not vary by gender (p = 0.99). During this period, there were 2,351 young adult registrations, and of these 1,492 (63%) were female. The proportion consenting for HIV testing was similar among females 980/1,492 (66%, 95% CI 63-68%) and males 543/859 (63%, 95% CI 60-66%, p = 0.25). Among the 1,523 (65%, 95% CI 63-67%) young adults who underwent testing, the HIV prevalence was 22% (95% CI 19-24%) in females versus 14% in males (95% CI 11-17%, p<0.01). Conclusions: Although the HIV prevalence is high among youth participating in an adult outpatient clinic routine HIV program, the uptake of testing is low, especially among 12-17 year old males. There is an urgent need to offer targeted, age-appropriate routine HIV testing to youth presenting to outpatient clinics in epidemic settings. [ABSTRACT FROM AUTHOR]

Background: Many HIV treatment programs in resource-limited settings are plagued by high rates of loss to follow-up (LTFU). Most studies have not distinguished between those who briefly interrupt, but return to care, and those more chronically lost to follow-up. Methods: We conducted a retrospective cohort study of 11,397 adults initiating antiretroviral therapy (ART) in 71 Southern African Catholic Bishops Conference/Catholic Relief Services HIV treatment clinics between January 2004 and December 2008. We distinguished among patients with early death, within the first 7 months on ART; patients with interruptions in laboratory monitoring (ILM), defined as missing visits in the first 7 months on ART, but returning to care by 12 months; and those LTFU, defined as missing all follow-up visits in the first 12 months on ART. We used multilevel logistic regression models to determine patient and clinic-level characteristics associated with these outcomes. Results: In the first year on ART, 60% of patients remained in care, 30% missed laboratory visits, and 10% suffered early death. Of the 3,194 patients who missed laboratory visits, 40% had ILM, resuming care by 12 months. After 12 months on ART, patients with ILM had a 30% increase in detectable viremia compared to those who remained in care. Risk of LTFU decreased with increasing enrollment year, and was lowest for patients who enrolled in 2008 compared to 2004 [OR 0.49, 95%CI 0.39-0.62]. Conclusions: In a large community-based cohort in South Africa, nearly 30% of patients miss follow-up visits for CD4 monitoring in the first year after starting ART. Of those, 40% have ILM but return to clinic with worse virologic outcomes than those who remain in care. The risk of chronic LTFU decreased with enrollment year. As ART availability increases, interruptions in care may become more common, and should be accounted for in addressing program LTFU. [ABSTRACT FROM AUTHOR]

The article focuses on a study conducted by the authors related to antiretroviral therapy's (ART) cost effectiveness for serodiscordant HIV positive couple. It states that ART was cost effective over a period of five years in both South Africa and India. It highlights that it was very cost effective if the cost-effectiveness ratio was less than the gross domestic product (GDP).

Setting: We conducted a retrospective study among HIV-infected adult suspects (≥18 years) with pulmonary tuberculosis (TB), who underwent Xpert MTB/RIF (Xpert) testing at McCord Hospital and its adjoining HIV clinic in Durban, South Africa., Objective: To determine if Xpert testing performed at a centralized laboratory accelerated time to TB diagnosis., Design: We obtained data on sputum smear microscopy [acid-fast bacilli (AFB)], Xpert, and the rationale for treatment initiation from medical records. The primary outcome was "total diagnostic time," defined as time from sputum collection to clinicians' receipt of results. A linear mixed-effect model compared the duration of steps in the diagnostic pathway across testing modalities., Results: Among 403 participants, the median "total diagnostic time" for AFB and Xpert was 3.3 and 6.4 days, respectively (P < 0.001). When compared with AFB, the median delay for Xpert "laboratory processing" was 1.4 days (P < 0.001) and "result transfer to clinic" was 1.7 days (P < 0.001). Among 86 Xpert-positive participants who initiated treatment, 49 (57%) started treatment based on clinical suspicion or AFB-positive results, whereas only 32 (37%) started treatment based on Xpert-positive results., Conclusions: In our setting, Xpert results took twice as long as AFB results to reach clinicians. Replacing AFB with centralized Xpert may delay TB diagnoses in some settings.

Background: Mobile HIV screening may facilitate early HIV diagnosis. Our objective was to examine the cost-effectiveness of adding a mobile screening unit to current medical facility-based HIV testing in Cape Town, South Africa., Methods and Findings: We used the Cost Effectiveness of Preventing AIDS Complications International (CEPAC-I) computer simulation model to evaluate two HIV screening strategies in Cape Town: 1) medical facility-based testing (the current standard of care) and 2) addition of a mobile HIV-testing unit intervention in the same community. Baseline input parameters were derived from a Cape Town-based mobile unit that tested 18,870 individuals over 2 years: prevalence of previously undiagnosed HIV (6.6%), mean CD4 count at diagnosis (males 423/µL, females 516/µL), CD4 count-dependent linkage to care rates (males 31%-58%, females 49%-58%), mobile unit intervention cost (includes acquisition, operation and HIV test costs, $29.30 per negative result and $31.30 per positive result). We conducted extensive sensitivity analyses to evaluate input uncertainty. Model outcomes included site of HIV diagnosis, life expectancy, medical costs, and the incremental cost-effectiveness ratio (ICER) of the intervention compared to medical facility-based testing. We considered the intervention to be "very cost-effective" when the ICER was less than South Africa's annual per capita Gross Domestic Product (GDP) ($8,200 in 2012). We projected that, with medical facility-based testing, the discounted (undiscounted) HIV-infected population life expectancy was 132.2 (197.7) months; this increased to 140.7 (211.7) months with the addition of the mobile unit. The ICER for the mobile unit was $2,400/year of life saved (YLS). Results were most sensitive to the previously undiagnosed HIV prevalence, linkage to care rates, and frequency of HIV testing at medical facilities., Conclusion: The addition of mobile HIV screening to current testing programs can improve survival and be very cost-effective in South Africa and other resource-limited settings, and should be a priority.

Background: Limited access to HIV testing of children impedes early diagnosis and access to antiretroviral therapy. Our objective was to evaluate the feasibility and acceptability of routine pediatric HIV testing in an urban, fee-for-service, outpatient clinic in Durban, South Africa., Methods: We assessed the number of patients (0-15 years) who underwent HIV testing upon physician referral during a baseline period. We then established a routine, voluntary HIV testing study for pediatric patients, regardless of symptoms. Parents/caretakers were offered free rapid fingerstick HIV testing of their child. For patients <18 months, the biological mother was offered HIV testing and HIV DNA polymerase chain reaction was used to confirm the infant's status. The primary outcome was the HIV testing yield, defined as the average number of positive tests per month during the routine compared with the baseline period., Results: Over a 5-month baseline testing period, 931 pediatric patients registered for outpatient care. Of the 124 (13%) patients who underwent testing on physician referral, 21 (17%, 95% confidence interval: 11-25%) were HIV infected. During a 13-month routine testing period, 2790 patients registered for care and 2106 (75%) were approached for participation. Of these, 1234 were eligible and 771 (62%) enrolled. Among those eligible, 637 (52%, 95% confidence interval: 49-54%) accepted testing of their child or themselves (biological mothers of infants <18 months). There was an increase in the average number of HIV tests during the routine compared with the baseline HIV testing periods (49 versus 25 tests/month, P = 0.001) but no difference in the HIV testing yield during the testing periods (3 versus 4 positive HIV tests/month, P = 0.06). However, during the routine testing period, HIV prevalence remains extraordinarily high with 39 (6%, 95% confidence interval: 4-8%) newly diagnosed HIV-infected children (median 7 years, 56% female)., Conclusions: Targeted and symptom-based testing referral identifies an equivalent number of HIV-infected children as routine HIV testing. Routine HIV testing identifies a high burden of HIV and is a feasible and moderately acceptable strategy in an outpatient clinic in a high prevalence area.

Background: HIV counseling and testing may serve as an entry point for non-communicable disease screening., Objectives: To determine the yield of newly-diagnosed HIV, tuberculosis (TB) symptoms, diabetes and hypertension, and to assess CD4 count testing, linkage to care as well as correlates of linkage and barriers to care from a mobile testing unit., Methods: A mobile unit provided screening for HIV, TB symptoms, diabetes and hypertension in Cape Town, South Africa between March 2010 and September 2011. The yield of newly-diagnosed cases of these conditions was measured and clients were followed-up between January and November 2011 to assess linkage. Linkage to care was defined as accessing care within one, three or six months post-HIV diagnosis (dependent on CD4 count) and one month post-diagnosis for other conditions. Clinical and socio-demographic correlates of linkage to care were evaluated using Poisson regression and barriers to care were determined., Results: Of 9,806 clients screened, the yield of new diagnoses was: HIV (5.5%), TB suspects (10.1%), diabetes (0.8%) and hypertension (58.1%). Linkage to care for HIV-infected clients, TB suspects, diabetics and hypertensives was: 51.3%, 56.7%, 74.1% and 50.0%. Only disclosure of HIV-positive status to family members or partners (RR=2.6, 95% CI: 1.04-6.3, p=0.04) was independently associated with linkage to HIV care. The main barrier to care reported by all groups was lack of time to access a clinic., Conclusion: Screening for HIV, TB symptoms and hypertension at mobile units in South Africa has a high yield but inadequate linkage. After-hours and weekend clinics may overcome a major barrier to accessing care.

Background: In settings with high tuberculosis (TB) prevalence, 15-30% of HIV-infected individuals initiating antiretroviral therapy (ART) have undiagnosed TB. Such patients are usually screened by symptoms and sputum smear, which have poor sensitivity., Objective: To project the clinical and economic outcomes of using Xpert MTB/RIF(Xpert), a rapid TB/rifampicin-resistance diagnostic, to screen individuals initiating ART., Design: We used a microsimulation model to evaluate the clinical impact and cost-effectiveness of alternative TB screening modalities - in all patients or only symptomatic patients - for hypothetical cohorts of individuals initiating ART in South Africa (mean CD4 cell count = 171 cells/μl; TB prevalence 22%). We simulated no active screening and four diagnostic strategies, smear microscopy (sensitivity 23%); smear and culture (sensitivity, 100%); one Xpert sample (sensitivity in smear-negative TB: 43%); two Xpert samples (sensitivity in smear-negative TB: 62%). Outcomes included projected life expectancy, lifetime costs (2010 US$), and incremental cost-effectiveness ratios (ICERs). Strategies with ICERs less than $7100 (South African gross domestic product per capita) were considered very cost-effective., Results: Compared with no screening, life expectancy in TB-infected patients increased by 1.6 months using smear in symptomatic patients and by 6.6 months with two Xpert samples in all patients. At 22% TB prevalence, the ICER of smear for all patients was $2800 per year of life saved (YLS), and of Xpert (two samples) for all patients was $5100/YLS. Strategies involving one Xpert sample or symptom screening were less efficient., Conclusion: Model-based analysis suggests that screening all individuals initiating ART in South Africa with two Xpert samples is very cost-effective.

Objective: Gender differences in the association between depression and smoking has received inconsistent support among youth in national samples in the United States and other countries. However, the examination of depression and smoking among South African male and female youth has not been sufficiently studied. This paper examines gender differences in the association between depression, racially classified social group (RCSG) status, social amenities, and grade level with smoking among South African youth in Cape Town., Design: Six-hundred twenty students completed a questionnaire on socio-demographic characteristics, smoking, and depression. Separate logistic regression procedures were conducted by gender to assess significant variations in correlates of ever smoker versus never smoker status and current smoker versus nonsmoker status. Variables included in the models were Beck Depression Inventory scores, RCSG, social amenities, and grade level., Results: Primary analyses revealed that among girls, mild and severe depression were significant predictors of ever smoking status. In addition, girls who suffered from mild, moderate, and severe forms of depression were more likely to be current smokers than nonsmokers. Among boys, depression was not a significant predictor of smoking status., Conclusions: The results support the need to incorporate mental health education strategies into smoking intervention programs, especially among school girls in Cape Town, South Africa.

Objective: The aim of this article is twofold: first, to examine the prevalence of being the victim of actual and attempted rape among a large representative sample of Cape Town high school students; and second, to identify the correlates of sexual assault for both boys and girls, including alcohol, tobacco and other drug use, behavioral problems, and suicidality., Method: Data for this study were derived from the 1997 South African Community Epidemiology Network on Drug Use (SACENDU) school survey. A stratified sampling procedure was used to select students in Grades 8 and 11 at non-private high schools in Cape Town. A total of 2,946 students completed a survey consisting of socio-demographic questions and items about substance abuse, sexual activity, and other adolescent health risk behaviors. A subsample of 939 was randomly selected to complete items about sexual violence., Results: The results revealed that 8.4% of respondents were victims of attempted rape, while 5.8% were victims of actual rape. Ordinal logistic regression showed that girls were 3.9 times more likely than boys to have been victims of sexual abuse. Family structure was also significantly related to rape as persons who lived with a single parent (OR = 1.74, CI = 1.00-3.04) and those who resided with one biological parent and one step parent (OR = 2.59, CI = 1.34-5.01) were more likely to have been have been victims of sexual abuse than those living with both biological parents. Alcohol use (OR = 2.0, CI = 1.10-3.62), anti-social behavior (stolen property, caused physical damage to property, bullied others, or been in physical fights) (OR = 1.44, CI = 1.12-1.86), suicidal dialogue (OR = 2.48, CI = 1.19-5.19), and suicidal attempts (OR = 3.2, CI = 1.65-6.30) were also significant predictors of sexual abuse victimization. Racially classified social groups (RCSG), age, drug use, and cigarette smoking were not significant predictors of sexual abuse victimization, while socioeconomic status was found to be marginally significant., Conclusion: This study reinforces the importance of multiple factors including alcohol use, anti-social behavior, suicidal thoughts and actions, and family structure with respect to sexual assault of adolescents in South Africa. Establishing and strengthening intervention programs, school based child protective protocols, professional education of teachers and school personnel, community prevention programs, and initiatives could help prevent adolescent sexual violence and reduce the sequelae associated with this problem.
