In resource-limited settings, holding regimens such as lamivudine monotherapy (LAM) have been used to manage HIV-positive children failing combination antiretroviral therapy to mitigate the risk of drug resistance developing, while adherence barriers are addressed or when access to second- or third-line regimens is restricted. South African HIV treatment guidelines previously advocated the use of LAM to manage HIV-infected children with virological failure. However, the outcomes of patients on LAM compared with those who continued on a failing regimen have not been well described. Objectives. ⋯ There was no statistical difference between the two groups with regard to overall time to immunological deterioration (log-rank p-value 0.4810). Conclusion. Given that a higher proportion of children in the LAM group experienced immunological failure, the LAM strategy may be a useful short-term one but should be restricted to children with limited treatment options. Managing children with virological failure will continue to be a challenge until improved adherence strategies are available.

Diabetes mellitus (DM) is a complex chronic condition and remains a public health concern worldwide. In South Africa (SA), many patients with DM access public sector primary healthcare clinics, and those who are considered to be stable are referred to the club system, which is managed by a multidisciplinary team. Patients who have DM are often diagnosed with concurrent medical conditions, resulting in multiple medication therapies that lead to medication therapy problems (MTPs). ⋯ Pharmacists can identify, resolve and prevent MTPs and rationalise appropriate medication therapy in patients with DM. Prescriber uptake of pharmacists' pharmacotherapeutic recommendations seems overlooked. Pharmacist-led workshops to advocate for rational prescribing are needed to mitigate MTPs among stable patients with type 2 DM at public sector healthcare facilities.

Dobutamine stress echocardiography (DSE) is a well-established modality for the diagnosis of coronary artery disease, but there are no reported diagnostic data in southern Africa. Objectives. To compare the safety, sensitivity and specificity of a South African (SA) DSE programme with larger, international series. Methods. All patients undergoing DSE from 2019 to 2021 at a single SA centre were included. ⋯ The sensitivity and specificity for epicardial coronary stenosis were 77% and 74%, respectively, changing to 82% and 72% when excluding those who had previous coronary artery bypass surgery. Conclusion. The sensitivity, specificity and safety of an SA DSE programme were comparable to international series. A DSE programme is feasible in a resource-constrained environment.

South African (SA) gamete banks and gamete donation agencies do not offer open-identity donors, as it is generally believed that donor anonymity is a legal requirement in SA. However, analysis of SA statutory instruments and case law shows that this belief is mistaken, and that gamete donation in SA can be anywhere on the spectrum between anonymous and known. Accordingly, open-identity gamete donation would be lawful in SA and can be offered to the public by SA gamete banks and gamete donation agencies.
