In 2022, the Wits Transplant Unit performed 57 liver transplants: 33/57 adult (58%) and 24/57 paediatric (42%) recipients. At the beginning of 2022, 28 candidates were on the adult waitlist. Forty-six candidates were added to the waitlist during the year. ⋯ There was a decrease in paediatric pretransplant mortality from 27% in 2017 to 6% in 2021. Unlike the adult cohort, most paediatric recipients received a living donor graft (79%). Unadjusted one-year and three-year survival rates were 85% (95% CI 75 - 92) and 68% (95% CI 56 - 77), respectively.

Pregnancy in kidney and liver transplant recipients presents unique challenges and risks for both maternal and fetal health. This article examines the management of pregnancy in kidney and liver transplant recipients, focusing on pre-pregnancy counselling, trimester-specific care, the teratogenic effects of immunosuppressive drugs, and the role of the multidisciplinary team. While South African (SA) data on this topic are limited, the Transplant Pregnancy Registry International has provided valuable insights. ⋯ By addressing the complexities of managing pregnant women with kidney or liver transplants, this article underscores the importance of tailored care and the involvement of various medical specialists. It also explores the safety of and potential complications associated with specific immunosuppressive therapies during pregnancy. Further research is needed to enhance our understanding and optimise the management of these high-risk pregnancies in SA.

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.
