HIV-infected kidney transplant recipients with COVID-19 are at increased risk of acute illness and death owing to their underlying comorbidities and chronic immunosuppression. ⋯ In our case series, ~10% of the HIV-positive-to-HIV-positive transplant recipients died of COVID-19 pneumonia. This mortality rate appears higher than figures reported in other transplant cohorts. However, it is likely that the actual number of cases of SARS-CoV-2 infection was much higher, as the study only included polymerase chain reaction-confirmed cases. It remains unclear whether HIV infection, transplant or the combination of the two drives poorer outcomes, and larger studies adjusting for important demographic and biological factors may isolate these effects.

Renal transplantation is the gold-standard therapy for end-stage renal disease. Decision-making around the acceptance of deceased-donor organs is complex and time sensitive. Risk scoring systems for both donors and recipients attempt to simplify the allocation of renal grafts to the most appropriate recipient. ⋯ Deceased-donor and renal recipient risk scores commonly used internationally performed poorly in predicting graft survival in our cohort, and should be used with caution in the SA setting. A conservative approach to organ donor referral and utilisation as well as renal transplant recipient listing was noted.

Diabetes mellitus (DM) is a growing public health concern in South Africa (SA) and poses a substantial economic burden on healthcare globally. A century has passed since the discovery of insulin, and despite advances in diabetes management, exogenous insulin remains a primary treatment for type 1 DM, posing challenges of hyperglycaemia and hypoglycaemia. Pancreas transplantation should be considered a treatment for insulin-deficient DM, offering sustained euglycaemia and preventing complications associated with the disease. ⋯ In SA, only a few pancreas transplants have been performed, primarily because of surgical risks and the need for immunosuppression. Islet transplantation is an alternative but faces limitations due to donor scarcity and immunosuppression requirements. This review explores recent progress in pancreas and islet transplants for DM, with the aim of providing insights into expanding treatment options for people with insulin-deficient DM.

Observational Study
Kidney transplant utilising donors after circulatory death: The first report from the African continent.
At Groote Schuur Hospital in Cape Town, South Africa, the number of deceased organ donors has declined over the past 2 decades, necessitating a more liberal approach to donor selection. In 2007, measures to expand the deceased kidney donor pool were implemented, including an HIV positive-to-positive transplant programme and the utilisation of extended-criteria donors as well as donors after circulatory death (DCDs). ⋯ Long-term graft and patient survival was comparable with the international literature. DCD may present a unique opportunity to expand deceased donation throughout Africa, particularly in areas affected by a lack of brain death legislation and religious or cultural objections to donation after brain death.

Prostate cancer (PCa) is one of the most commonly diagnosed cancers among men, with a rising global incidence. Currently, the PCa landscape is vastly different between developed countries and Africa. ⋯ This review will focus on the burden of PCa globally and in Africa, compare the state of the disease in Africa with that in more developed regions of the world, and answer the question why it can sometimes look like a 'different' disease compared with developed regions. In addition, we address the racial disparities of PCa.
