Obese Patients May Benefit More From Liver Transplantation

Centers that avoid liver transplants in morbidly obese patients may want to reconsider this practice, according to researchers presenting data at the American Association for the Study of Liver Diseases' Liver Meeting.

Barry Schlansky, MD, MPH, C. Kristian Enestvedt, MD, and colleagues from Oregon Health and Science University used data from the U.S. national transplant database to investigate if morbidly obese patients fared worse than patients with a lower BMI following a liver transplant.

The researchers followed patients from the “time of their transplant to death or graft loss, from wait listing to death before [liver transplant] or receipt of [liver transplant], and from wait listing to death before or after [liver transplant] (intention-to-treat).”

Their analysis noted that “3.9% of 80 221 waitlisted patients and 3.5% of 38 177 transplanted patients were morbidly obese,” and that survival rates after liver transplantation for morbidly obese patients have improved.

"Our study revealed that obese patients benefit more from liver transplantation than lower weight patients, and suggests that we should consider lowering weight restrictions for patients who are otherwise good candidates for liver transplant," Dr Schlansky said in a press release about the study.

“Obesity brings unique challenges to liver transplantation, such as increased risks of diabetes, heart and kidney disease,” Dr Schlansky continued. “The liver transplant community will have to learn how to better deal with these issues if we begin transplanting more patients.
