PHILADELPHIA — Older adults with end-stage kidney disease undergoing bariatric surgery may be more likely to achieve kidney transplant, according to data presented at the American Transplant Congress.
However, “with increasing age, frailty and comorbid conditions,” researchers found bariatric surgery was linked to an increased mortality risk.
Using 2006 to 2015 data from the United States Renal Data System, Tanveen Ishaque, of NYU Langone Health, and colleagues identified 123 adults who were 65 years or older, had at least class II obesity, ESKD and bariatric surgery and matched them with 369 control patients who did not undergo bariatric surgery and received usual care.
Researchers found 15.5% of patients who had bariatric surgery achieved kidney transplant compared with 3.3% of patients in the control group. Patients who had bariatric surgery had a 3.4-fold higher chance of having a kidney transplant compared with controls after accounting for competing mortality risk. Ishaque and colleagues found 47.9% of patients who had bariatric surgery died within 1 year compared with 16.3% of patients in the control cohort. Researchers found bariatric surgery was linked with a 1.6-fold increase in 5-year all-cause mortality vs. controls.
“Extreme caution should be exercised in considering bariatric surgery as an option for older adults with end-stage kidney disease,” Ishaque said.
