Clinical profile and outcome of kidney transplantation at Muhimbili National Hospital, Tanzania.

Abstract

Kidney transplantation is the definitive treatment option for chronic kidney failure, offering improved quality of life and extended survival. Access to kidney transplantation is limited in the Sub-Saharan Africa (SSA) region, with only a few countries with established services. Tanzania started its program five years ago, for the sustainability of the program it is important to understand the outcome. Therefore, this study was conducted to determine the clinical outcomes and survival rates of kidney transplant recipients at Muhimbili National Hospital in Tanzania, in the absence of a national transplant registry, since the inception of the program. This was a retrospective study conducted among kidney transplant recipients from live donors at Muhimbili National Hospital (MNH) between November 2017 and February 2022. Analyses were performed to assess baseline characteristics, post-transplant complications, and patient and graft survival. In our study of 68 kidney transplant recipients, the majority of recipients were male (63.2%) with a mean age of 45.8 years and under medical insurance (88.2%). The predominant cause of CKD was hypertension (58.2%) with recipients undergoing dialysis for a mean duration of 14.4 months, and basiliximab being the most commonly used induction medication (57.3%). The majority of donors were males (64.7%) and had first-degree relationships with recipients (76.5%). Haploid HLA mismatch was observed in 36.8% of cases. One-year patient and graft survival rates were 91.2% and 96.7%, respectively, with infection being the primary cause of death (n = 5), and more than half of deceased patients died with a functioning graft (n = 4). Our study underscores favorable one-year patient and graft outcomes among kidney transplant recipients at Muhimbili National Hospital, Tanzania. However, challenges persist, notably with infections posing ongoing difficulties for this cohort.
