Abstract

Abstract: Post‐transplant diabetes mellitus is associated with long‐term immunosuppression and weight gain, and is related to an increased risk of cardiovascular disease, accelerated loss of graft and increased mortality. There is an absence of strong evidence‐based dietary guidelines for the prevention and management of post‐transplant diabetes mellitus in kidney transplant recipients. The aim of this study was to systematically review all dietary evidence for kidney transplant recipients on clinical outcomes relating to diabetes, patient‐reported outcomes and economic outcomes. A comprehensive literature search was conducted in August 2020 using the databases Medline, Embase, CENTRAL and CINAHL. Studies were critically appraised using Cochrane risk of bias tools and GRADE. A total of 12 studies and 1928 participants were included. Four papers focused on diet and exercise, one paper on diet only, two papers on magnesium supplementation, one paper on magnesium and fibre intake, two papers on Mediterranean diet, one paper on marine n‐3 fatty acid supplementation and one paper on fruit and vegetable intake. There were no significant effects on outcomes relating to dietary counselling, magnesium supplementation, magnesium and fibre intake or marine n‐3 fatty acid supplementation. Low‐quality evidence supports the Mediterranean diet in reducing the risk of post‐transplant diabetes mellitus and fasting plasma glucose levels. Low‐quality evidence suggests vegetable intake being associated with a lower risk of post‐transplant diabetes mellitus. This review demonstrates limited evidence for dietary interventions in the prevention and management of diabetes in post‐kidney transplantation. The findings suggest that further high‐quality research with robust study designs is required. SUMMARY AT A GLANCE: This systematic review demonstrates limited evidence for dietary interventions in the prevention and management of diabetes in post‐kidney transplantation. There are low‐quality evidence supporting the Mediterranean diet and vegetable intake in reducing the risk of post‐transplant diabetes mellitus.
