Abstract
Purpose: The prevalence of obesity is increasing among patients with end-stage renal disease (ESRD). Metabolic and bariatric surgery (MBS) is an effective method for weight loss in this population. This study aims to examine the trends and outcomes in kidney transplant (KT) among patients with advanced chronic kidney disease (CKD) who underwent MBS. Methods: A retrospective review was conducted of all patients undergoing MBS between January 1, 2012, and Dec 31, 2024, within a large metropolitan health care system. Patients with CKD stage 5, ESRD, or history of KT at the time of MBS were identified and demographic information and comorbidities were examined. The log-rank test was used to compare patient and graft survival. Results: Fifty-eight patients were included, with a median age of 47 years and a median BMI of 43.8 kg/m2. Forty-one (70.7%) patients were female and 42 (73.4%) were Black. Hypertension and/or diabetes accounted for 75.8% of etiology, while cardiovascular disease (CVD) was present in 94.6%. (Table1)Twenty-nine patients underwent KT, of which 18 received KT before MBS and 11 after. No significant differences were observed in patient characteristics between the two groups(Table1). There was no significant difference in patient survival (p=0.979) between patients with or without KT(Fig.1). Among patients undergoing KT, no significant difference in patient (p=0.326) or graft survival (p=0.078) was observed based on timing of KT either before or after MBS. Black patients tended to have lower graft survival (p=0.070). A total of 13 (32.5%) patients were declined listing for KT after MBS. The reasons for decline included low cardiac function (30.8%), persistent obesity (15.4%), and other physical problems (15.4%). (Fig.2) Conclusions: MBS appears to be associated with similar patient and graft survival both before and after KT. Despite undergoing MBS nearly one-third of patients with CKD are declined listing for KT.
