Background: Depression is a leading cause of disability and may be associated with decreased adherence to ART. We sought to describe the prevalence of depressive symptoms and outcomes one year after screening among patients receiving ART at a large HIV Clinic in Johannesburg, South Africa. Methods: Adult (≥18) patients who had been on first-line ART between 6–18 months who could communicate in English were eligible. Depressive symptoms were evaluated using the Patient Health Questionnaire (PHQ)-9 and a score ≥10 indicated depression. Results: 97 patients enrolled. Patients had been on ART for a median (IQR) of 8 (7–10) months, 61% were female, the median (IQR) age at enrollment was 38 (33–42) years, and the median (IQR) CD4 count at ART initiation was 154.5 (65–263) cells/mm3. 7 (7%) patients were found to have symptoms of depression; 4 (4%) had symptoms of moderate depression (PHQ score of 10–14) and 3 (3%) had symptoms of moderate/severe depression (PHQ score of 15–19). Women (10%) were more likely to have symptoms of depression than men (3%; prevalence difference [PD]: 7.5%; 95% confidence interval [CI]:-1.7%-16.8%); as were patients under the age of 30 (14%) compared to those 30–39 (4%; PD: -10.2; 95% CI: -29.4–9.0%) or ≥40 (9%; PD: -5.5%; -26.1%-15.2%), those with lower CD4 counts at ART initiation (<200 cells/mm3 vs ≥200 cells/mm3: 8% vs 3%; PD: 4.8%; 95% CI: -4.5%-14.0%), and those with high viral loads (>1000 copies/mL vs. <400 copies/mL: 40% vs. 5%; PD: 34.6%; 95% CI: -8.6%-77.6%). No relationship between depressive symptoms and retention in HIV care one year after screening was observed. Conclusions: We found a lower prevalence of depressive symptoms compared to findings from other HIV-positive populations in South Africa but more than one-third of patients with an elevated viral load had evidence of depression. Further research on the relationship between depression, adherence, and viral failure is warranted as this may present an opportunity for early interventions to improve treatment outcomes and reduce the need for second-line treatment.

Background: In 2010 South Africa revised its HIV treatment guidelines to allow the initiation and management of patients on antiretroviral therapy (ART) by nurses, rather than solely doctors, under a program called NIMART (Nurse Initiated and Managed Antiretroviral Therapy). We compared the outcomes and costs of NIMART between the two major public sector HIV treatment delivery models in use in South Africa today, primary health clinics and hospital-based HIV clinics. Methods and findings: The study was conducted at one hospital-based outpatient HIV clinic and one primary health clinic (PHC) in Gauteng Province. A retrospective cohort of adult patients initiated on ART at the PHC was propensity-score matched to patients initiated at the hospital outpatient clinic. Each patient was assigned a 12-month outcome of alive and in care or died/lost to follow up. Costs were estimated from the provider perspective for the 12 months after ART initiation. The proportion of patients alive and in care at 12 months did not differ between the PHC (76.5%) and the hospital-based site (74.2%). The average annual cost per patient alive and in care at 12 months after ART initiation was significantly lower at the PHC (US$238) than at the hospital outpatient clinic (US$428). Conclusions: Initiating and managing ART patients at PHCs under NIMART is producing equally good outcomes as hospital-based HIV clinic care at much lower cost. Evolution of hospital-based clinics into referral facilities that serve complicated patients, while investing most program expansion resources into PHCs, may be a preferred strategy for achieving treatment coverage targets.

Background: Little is known about the impact of pregnancy on response to highly active antiretroviral therapy (HAART) in sub-Saharan Africa. We examined the effect of incident pregnancy after HAART initiation on clinical response to HAART. Methods: We evaluated a prospective clinical cohort of adult women initiating HAART in Johannesburg, South Africa between 1 April 2004 and 31 March 2011, and followed up until an event, transfer, drop-out, or administrative end of follow-up on 30 September 2011. Women over age 45 and women who were pregnant at HAART initiation were excluded from the study. Main exposure was having experienced pregnancy after HAART initiation; main outcome was death and (separately) death or new AIDS event. We calculated adjusted hazard ratios (HRs) and 95% confidence limits (CL) using marginal structural Cox proportional hazards models. Results: The study included 7,534 women, and 20,813 person-years of follow-up; 918 women had at least one recognized pregnancy during follow-up. For death alone, the weighted (adjusted) HR was 0.84 (95% CL 0.44, 1.60). Sensitivity analyses confirmed main results, and results were similar for analysis of death or new AIDS event. Incident pregnancy was associated with a substantially reduced hazard of drop-out (HR = 0.62, 95% CL 0.51, 0.75). Conclusions: Recognized incident pregnancy after HAART initiation was not associated with increases in hazard of clinical events, but was associated with a decreased hazard of drop-out. High rates of pregnancy after initiation of HAART may point to a need to better integrate family planning services into clinical care for HIV-infected women. [ABSTRACT FROM AUTHOR]

Objective: To assess the outcomes of linkage to TB and HIV care and identify risk factors for poor referral outcomes. Design: Cohort study of TB patients diagnosed at an urban hospital. Methods: Linkage to care was determined by review of clinic files, national death register, and telephone contact, and classified as linked to care, delayed linkage to care (>7 days for TB treatment, >30 days for HIV care), or failed linkage to care. We performed log-binomial regression to identify patient and referral characteristics associated with poor referral outcomes. Results: Among 593 TB patients, 23% failed linkage to TB treatment and 30.3% of the 77.0% who linked to care arrived late. Among 486 (86.9%) HIV-infected TB patients, 38.3% failed linkage to HIV care, and 32% of the 61.7% who linked to care presented late. One in six HIV-infected patients failed linkage to both TB and HIV care. Only 20.2% of HIV-infected patients were referred to a single clinic for integrated care. A referral letter was present in 90.3%, but only 23.7% included HIV status and 18.8% CD4 cell count. Lack of education (RR 1.85) and low CD4 count (CD4≤50 vs. >250cells/mm³ ; RR 1.66) were associated with failed linkage to TB care. Risk factors for failed linkage to HIV care were antiretroviral-naïve status (RR 1.29), and absence of referral letter with HIV or CD4 cell count (RR1.23). Conclusions: Linkage to TB/HIV care should be strengthened by communication of HIV and CD4 results, ART initiation during hospitalization and TB/HIV integration at primary care. [ABSTRACT FROM AUTHOR]
