RESUMEN

Patients with class II and III obesity and end-stage renal disease are often ineligible for kidney transplantation (KTx) due to increased postoperative complications and technically challenging surgery. Bariatric surgery (BS) can be an effective solution for KTx candidates who are considered inoperable. The aim of this study is to evaluate outcomes of KTx after BS and to compare the outcomes to obese recipients (BMI ≥ 35 kg/m2 ) without BS. This retrospective, single-center study included patients who received KTx after BS between January 1994 and December 2018. The primary outcome was postoperative complications. The secondary outcomes were graft and patient survival. In total, 156 patients were included, of whom 23 underwent BS prior to KTx. There were no significant differences in postoperative complications. After a median follow-up of 5.1 years, death-censored graft survival, uncensored graft survival, and patient survival were similar to controls (log rank test p = .845, .659, and .704, respectively). Dialysis pre-transplantation (Hazard Ratio (HR) 2.55; 95%CI 1.03-6.34, p = .043) and diabetes (HR 2.41; 95%CI 1.11-5.22, p = .027) were independent risk factors for all-cause mortality. A kidney from a deceased donor was an independent risk factor for death-censored graft loss (HR 1.98; 95%CI 1.04-3.79, p = .038). Patients who received a KTx after BS have similar outcomes as obese transplant recipients.

RESUMEN

BACKGROUND: Obesity is becoming more prevalent in the end-stage renal disease population. Bariatric surgery (BS) is increasingly considered as an approach to become eligible for kidney transplant (KT) or reduce obesity-related morbidities. OBJECTIVES: To assess the short- and long-term outcomes of patients who underwent both BS and KT and to determine the optimal timing of BS. METHODS: Patients who underwent both KT and BS between January 2000 and December 2020 were included and stratified according to the sequence of the 2 operations. The primary outcomes were patient and graft survival. The secondary outcomes were postoperative complications and efficacy of weight loss. RESULTS: Twenty-two patients were included in the KT first group and 34 in the BS first group. Death-uncensored graft survival in the KT first group was significantly higher than in the BS first group (90.9% versus 71.4%, P = .009), without significant difference in patient survival and death-censored graft survival (100% versus 90.5%, P = .082; 90.9% versus 81.0%, P = .058). There was no significant difference in 1-year total weight loss (1-yr TWL: median [interquartile range {IQR}], 36.0 [28.0-42.0] kg versus 29.6 [21.5-40.6] kg, P = .424), 1-year percentage of excess weight loss (1-yr %EWL: median [IQR], 74.9 [54.1-99.0] versus 57.9 [47.5-79.4], P = .155), and the incidence of postoperative complications (36.4% versus 50.0%, P = .316) between the KT first and BS first groups. CONCLUSION: Both pre- and posttransplant BS are effective and safe. Different conditions of each transplant candidate should be considered in detail to determine the optimal timing of BS.

RESUMEN

UNLABELLED: Bariatric surgery is in general the only effective treatment for morbid obesity. Bariatric surgery is frequently associated with vitamin and mineral deficiencies which may lead to neurological and other symptoms. We describe a case of severe vitamin B1 (thiamine) deficiency. CASE DESCRIPTION: A 49-year-old man visited the emergency department with acute confusion, muscle weakness in arms and legs and visual impairment after a period of dysphagia and recurrent vomiting. Four months earlier, he had had bariatric gastric sleeve surgery for morbid obesity. Laboratory tests demonstrated that he had vitamin B1 deficiency, in view of which the diagnosis of beriberi and Wernicke encephalopathy was made. Despite normalisation of the vitamin B1 concentration following intravenous supplementation, the muscle strength hardly recovered and the patient developed Korsakov syndrome. CONCLUSION: For this deficiency there is no other treatment than vitamin B1 supplementation. Timely recognition of vitamin deficiencies and pro-active supplementation are essential in order to prevent serious complications following bariatric surgery.
