These guidelines are intended as an update to those published in the Southern African Journal of HIV Medicine in 2014 and the update on when to initiate antiretroviral therapy in 2015. Since the release of the previous guidelines, the scale-up of antiretroviral therapy (ART) in southern Africa has continued. New antiretroviral drugs have become available with improved efficacy, safety and robustness. The guidelines are intended for countries in the southern African region, which vary between lower and middle income.

High mortality rates among asymptomatic cryptococcal antigen (CrAg)–positive patients identified through CrAg screening, despite preemptive fluconazole treatment, may be due to undiagnosed cryptococcal meningitis. Symptoms were reviewed in CrAg-positive patients identified by screening 19233 individuals with human immunodeficiency virus infection and CD4 cell counts <100/µL at 17 clinics and 3 hospitals in Johannesburg from September 2012 until September 2015, and at 2 hospitals until June 2016. Cerebrospinal fluid samples from 90 of 254 asymptomatic patients (35%) and 78 of 173 (45%) with headache only were analyzed for cryptococcal meningitis, considered present if Cryptococcus was identified by means of India ink microscopy, culture, or CrAg test. CrAg titers were determined with stored blood samples from 62 of these patients. The associations between blood CrAg titer, concurrent cryptococcal meningitis, and mortality rate were assessed. Cryptococcal meningitis was confirmed in 34% (95% confidence interval, 25%–43%; 31 of 90) of asymptomatic CrAg-positive patients and 90% (81%–96%; 70 of 78) with headache only. Blood CrAg titer was significantly associated with concurrent cryptococcal meningitis in asymptomatic patients (P < .001) and patients with headache only (P = .003). The optimal titer for predicting cryptococcal meningitis was >160 (sensitivity, 88.2%; specificity, 82.1%); the odds ratio for concurrent cryptococcal meningitis was 34.5 (95% confidence interval, 8.3–143.1; P < .001). About a third of asymptomatic CrAg-positive patients have concurrent cryptococcal meningitis. More effective clinical assessment strategies and antifungal regimens are required for CrAg-positive patients, including investigation for cryptococcal meningitis irrespective of symptoms. Where it is not possible to perform lumbar punctures in all CrAg-positive patients, blood CrAg titers should be used to target those most at risk of cryptococcal meningitis.

The study aimed to describe the prevalence of and risk factors for post-COVID-19 condition (PCC). This was a prospective, longitudinal observational cohort study. Hospitalized and nonhospitalized adults were randomly selected to undergo telephone assessment at 1, 3, and 6 months. Participants were assessed using a standardized questionnaire for the evaluation of symptoms and health-related quality of life. We used negative binomial regression models to determine factors associated with the presence of ≥1 symptoms at 6 months. A total of 46.7% of hospitalized and 18.5% of nonhospitalized participants experienced ≥1 symptoms at 6 months (P ≤0.001). Among hospitalized people living with HIV, 40.4% had persistent symptoms compared with 47.1% among participants without HIV (P = 0.108). The risk factors for PCC included older age, female sex, non-Black race, presence of a comorbidity, greater number of acute COVID-19 symptoms, hospitalization/COVID-19 severity, and wave period (lower risk of persistent symptoms for the Omicron compared with the Beta wave). There were no associations between self-reported vaccination status with persistent symptoms. The study revealed a high prevalence of persistent symptoms among South African participants at 6 months but decreased risk for PCC among participants infected during the Omicron BA.1 wave. These findings have serious implications for countries with resource-constrained health care systems.

The Southern African Journal of HIV Medicine is focused on HIV/AIDS treatment, prevention and related topics relevant to clinical and public health practice. The purpose of the journal is to disseminate original research results and support high-level learning related to HIV Medicine. It publishes original research articles, editorials, case reports/case series, reviews of state-of-the-art clinical practice and correspondence.

We examined the prevalence of mental health conditions, social support, and associated factors among adolescents living with HIV. We conducted a cross-sectional analysis with adolescents (ages 9–19) attending a primary care clinic in Johannesburg, South Africa. We analyzed the results of four self-report tools: Children’s Depression Inventory–Short, Revised Manifest Anxiety Scale, Child Post-Traumatic Stress Disorder (PTSD) Checklist, and a modified version of the Medical Outcomes Study Social Support Scale. We used robust Poisson regression to quantify the association between social support and mental health. Among 278 adolescents, the majority were perinatally infected with HIV (92%), and had at least one deceased parent (59%). Depression symptom threshold scores were found among 8% of adolescents, and 7% screened positive for symptoms of anxiety. Few (1%) met the criteria for PTSD. Overall, 12% of adolescents screened positive for symptoms of depression, anxiety or PTSD. Older adolescents reported less social support than younger adolescents. Adolescents were less likely to have mental health symptoms if they had higher measures of social support (adjusted Prevalence Ratio 0.38, 95% CI 0.20–0.73). Attention should be paid to social support for adolescents living with HIV as this may play an important role in their mental health.
