A groundbreaking collaborative study between bariatric and transplant surgery teams has brought new hope to individuals suffering from end-stage renal disease (ESRD) and obesity.

 The study, published in the Journal of the American College of Surgeons, explored the effects of metabolic and bariatric surgery on ESRD patients, aiming to improve their eligibility for kidney transplantation.

Lead study author, Dr. Anil Paramesh, MD, MBA, FACS, professor of surgery, urology, and pediatrics, and director of the kidney and pancreas transplant programs at Tulane University School of Medicine, emphasized the growing concern of obesity in the United States and its impact on transplant eligibility. Dr. Paramesh spearheaded the Collaborative for Obesity Research in Transplantation (CORT) initiative, recognizing the urgent need to address this issue, particularly among underserved populations.

Patients with ESRD face numerous challenges, with dialysis being the primary alternative to prolong life. However, dialysis is costly, time-intensive, and significantly diminishes quality of life, Dr. Paramesh noted.

The study, conducted from January 2019 to June 2023, followed 183 ESRD patients referred for bariatric surgery, with 36 undergoing weight loss surgery and 10 subsequently receiving kidney transplants. Results revealed a remarkable 27% reduction in average BMI at the time of transplant, accompanied by improvements in hypertension and diabetes management. These enhancements in managing comorbid conditions significantly improved patients' overall health and transplant viability.

Given that obesity is a major factor in transplant exclusion, this collaborative program offers a promising solution for previously ineligible patients, Dr. Paramesh emphasized. Moreover, it may pave the way for increased patient education and access to life-saving procedures.

Dr. Paramesh highlighted the multifaceted benefits of bariatric surgery beyond weight loss, addressing serious conditions like diabetes, high blood pressure, and sleep apnea. This approach not only prepares patients for transplant surgery but also tackles broader health care disparities, particularly impacting Black and lower-income individuals.

Despite its successes, the study encountered challenges, including a high drop-off rate of patients unwilling or unable to undergo surgery, as well as unique postoperative complications such as hypotension.

Dr. Paramesh stressed the importance of enhancing patient education and support to ensure potential candidates understand the benefits of weight loss surgery and its role in improving transplant eligibility.

This innovative study marks a significant advancement in addressing the complex interplay between obesity, ESRD, and kidney transplantation, offering renewed hope and opportunities for patients previously facing daunting health challenges.
