RESUMEN
A large proportion of people living with HIV (PLHIV) in sub-Saharan Africa reside in rural areas. Knowledge of enablers and barriers of adherence to antiretroviral treatment (ART) in these populations is limited. We conducted a cohort study of 501 adult PLHIV on ART at a rural South African treatment facility as a sub-study of a clinical trial (ClinicalTrials.gov NCT03357588). Socio-economic, psychosocial and behavioral characteristics were assessed as covariates of self-reported adherence difficulties, suboptimal pill count adherence and virological failure during 96 weeks of follow-up. Male gender was an independent risk factor for all outcomes. Food insecurity was associated with virological failure in males. Depressive symptoms were independently associated with virological failure in both males and females. Household income and task-oriented coping score were protective against suboptimal pill-count adherence. These results underscore the impact of low household income, food insecurity and depression on outcomes of ART in rural settings and confirm other previously described risk factors. Recognition of these factors and targeted adherence support strategies may improve patient health and treatment outcomes.

HIV stigma may influence physical activity in people living with HIV (PLWH) and chronic pain. We prospectively examined the relationship between stigma, activity and chronic pain in a convenience sample of PLWH initiating antiretroviral therapy in an inner-city clinic in Johannesburg, South Africa. Participants wore accelerometers to measure daily duration and intensity of activity for 2 weeks. Stigma was assessed with the Revised HIV Stigma Scale. Participants [n = 81, 89% female, age mean (SD) 42 (8)] were active for a median of 7 h daily (IQR 5.2, 9.2), but at very low intensity, equivalent to a slow walk [median (IQR): 0.39 m s-1 (0.33, 0.50)]. Duration and intensity of activity was not associated with stigma, even after controlling for age, self-assessed wealth, pain intensity and willingness to engage in physical activity (p-values > 0.05). As stigma did not associate with greater activity, drivers of sustained activity in South African PLWH remain unclear.
RESUMEN: El estigma del VIH puede influir en la actividad física de las personas que viven con el VIH (PVVS) y el dolor crónico. Se examinó prospectivamente la relación entre el estigma, la actividad y el dolor crónico en una muestra de conveniencia de PVVS que iniciaba la terapia antirretroviral en una clínica del centro de la ciudad en Johannesburgo, Sudáfrica. Los participantes usaron acelerómetros para medir la duración diaria y la intensidad de la actividad durante dos semanas. El estigma se evaluó con la escala revisada de estigma del VIH. Los participantes [n = 81, 89% mujeres, media de edad (SD) 42 (8)] tenían una actividad de intensidad muy baja, para una mediana de siete horas diarias (IQR 5.2, 9.2), pero, equivalente a una marcha lenta [mediana (IQR): 0.39 m s−1 (0.33, 0.50)]. La duración y la intensidad de la actividad no se asociaron con los niveles de estigma, incluso después de controlar la edad, la riqueza autoevaluada, la intensidad del dolor y la voluntad de participar en la actividad física (valores de p > 0.05). Como el estigma no se asoció con una mayor actividad, los impulsores de la actividad sostenida en las PVVS sudafricanas siguen sin estar claros.

RESUMEN
This prospective non-randomized study of clinic attendees, compares self-reported HIV disclosure patterns in relation to access to antiretroviral access and counselling. It was carried out in public sector hospital HIV clinics in Johannesburg, South Africa, and 144 HIV-positive men and women attending the HIV clinics participated in the study.The results showed that there was no correlation between being on antiretroviral therapy and disclosure of HIV status. There was also no correlation between disclosure of HIV status and with different levels of counselling and access to support groups. Disclosure levels were high (92% told at least one person), however, there was a high level of delayed (15% greater than a year) or non-disclosure (21%) to partners. Family members and partners provided most moral support after disclosure. Having access to antiretroviral therapy and support groups and available counselling did not seem to affect disclosure patterns. It is possible that a patients beliefs about their treatment plays a more important role for disclosure than the actual treatment itself. Other factors are also likely important for disclosure, such as the patient's social network especially with their families, and knowledge of the disease.

OBJECTIVE: To assess whether adrenocortical function was compromised in patients with active tuberculosis (TB) during the first 5 days of therapy with either a rifampicin-based or ciprofloxacin-based regimen. DESIGN: Patients were randomised into two groups of 10 each. Adrenocortical function was compared in both groups by the measurement of biochemical indices, electrolytes, osmolality and pituitary-adrenocortical hormones. Adrenal reserve was assessed by intravenous 250 mug adrenocorticotropin hormone (ACTH) stimulation tests. SETTING: Department of Medicine, Johannesburg Hospital. SUBJECTS: Twenty hospitalised patients who were diagnosed with TB. OUTCOME MEASURES: Respiratory rate, pulse rate and blood pressure were recorded, and urinary sodium and osmolality were measured. Serum ACTH, cortisol, dehydroepiandrosterone- sulphate (DHEA-S) and aldosterone were assayed. RESULTS: None of the patients demonstrated biochemical evidence of overt adrenal insufficiency. There were no significant differences between the two groups before or during therapy for any biochemical indices, electrolytes, hormones or calculated osmolality. Mean basal cortisol concentrations were substantially elevated and DHEA-S levels were consistently subnormal, resulting in a high cortisol/ DHEA-S ratio. In the ciprofloxacin group, cortisol responses to ACTH stimulation on day 1 were not significantly lower than on day 5. In the rifampicin group, cortisol concentrations decreased at each time point on day 5 compared with day 1 (p = 0.001). However, a significantly higher mean incremental rise from the basal cortisol concentration was measured on day 5 at 60 minutes (p = 0.04). In the entire cohort of 20 patients, 40% demonstrated an incremental cortisol rise of < 250 nmol/l after ACTH stimulation on day 1. CONCLUSIONS: Rifampicin did not additionally impair adrenocortical function during the initial period of therapy. The high cortisol/DHEA-S ratio might be of clinical relevance.
