Abstract
The impact of different pretransplant dialysis modalities on post-transplant outcomes for pancreas-kidney transplantation is currently unclear. This study aims to assess the association between pretransplant dialysis modalities [hemodialysis (HD) and peritoneal dialysis] and outcomes following pancreas-kidney transplantation. The authors searched PubMed, EMBASE, and the Cochrane Library for relevant studies published from inception until 1 December 2023. The authors included studies that examined the relationship between pretransplant dialysis modalities and clinical outcomes for pancreas-kidney transplantation. The primary outcomes considered were patient, pancreas and kidney graft survival, and intra-abdominal infection. A total of 13 studies involving 1503 pancreas-kidney transplant recipients were included. Pretransplant HD was associated with improved pancreas graft survival (hazard ratio = 0.71, 95% confidence interval: 0.51-0.99, I ²=12%) and a decreased risk of intra-abdominal infection [odds ratio (OR)=0.69, 95% CI: 0.51-0.93, I ²=5%). However, no significant association was found between the dialysis modalities and patient or kidney graft survival. Furthermore, pretransplant HD was linked to a reduced risk of anastomotic leak (OR=0.32, 95% CI: 0.161-0.68, I ²=0%) and graft thrombosis (OR=0.56, 95% CI: 0.33-0.96, I ²=20%). Pretransplant HD is the preferred dialysis modality while awaiting pancreas-kidney transplantation, although well-designed prospective studies are needed to confirm these findings.
