Solid-organ transplantation (SOT) has been proven to be a highly effective and life-saving treatment modality for adults and children suffering from end-stage organ failure. However, high paediatric waiting-list mortality has been reported, and children may suffer irreversible physical and deleterious psychological effects if not transplanted timeously. ⋯ During the 14-year study period, only 15 deceased donors could be utilised for SOT, as a result of low in-hospital referral (5.9%) and consent rates (29%). The reasons for low referral and consent rates are complex and often multifactorial, which the current study was not designed to investigate in sufficient detail. Future studies should be designed to further interrogate our findings, while accommodating for nuances specific to the paediatric deceased-donor population and their families.

Extended-criteria donors (ECDs) are seen as a means of addressing the shortfall in solid-organ availability for transplant. However, the use of ECD kidneys is associated with a greater risk of primary non-function compared with standard-criteria donor kidneys, and a higher discard rate has been described internationally. There seems to be a lack of consensus in the consideration of ECD kidneys for transplant, with reliance often placed on the subjective assessment of individual clinicians. The following case examines the difference in the institutional decision-making process applied to two kidneys from a single donor, and provides an argument for the use of hypothermic machine perfusion in low- to middle-income countries as an efficacious and objective means of assessing ECD kidney suitability.

Liver transplantation is the definitive management for severe acute liver failure refractory to supportive management, and end- stage chronic liver failure. Owing to a shortage of deceased liver donors, South Africa requires innovative techniques to broaden the donor pool. ⋯ This study confirms ABOi-LT as a feasible option to increase the liver donor pool in this organ-depleted setting as recipient survival and complication rates were similar between ABO-compatibility groups.

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.
