Adequate weight loss by bariatric surgery may help improve albuminuria in severe obesity
In patients with severe obesity, albuminuria can be improved by both conventional medical therapy and bariatric surgery. In Japanese subjects with severe obesity, albuminuria may increase over time if only conventional medical therapy is continued.
Adequate weight loss by laparoscopic sleeve gastrectomy may help improve Albuminuria in severe obesity, finds a study conducted by Yasuhiro Watanabe and team.
The findings of this study were published in the journal, Obesity Facts on 14th October, 2021.
The goal of this study was to evaluate the influence of weight reduction accomplished by standard medical therapy vs laparoscopic sleeve gastrectomy (LSG) on albuminuria in Japanese patients with extreme obesity, as well as to determine the factors involved. The clinical parameters, including the urine albumin/creatinine ratio (UACR), of 340 consecutive patients with a BMI of 35 who underwent LSG (n = 242) or medicinal treatment (n = 98) between 2010 and 2018 and were followed for at least 12 months were examined retrospectively.
The primary findings of this study were that medical treatment alone did not prevent the increase in the UACR, but LSG prevented or even lowered the UACR, and that percent TWL contributed independently to the decrease in the UACR, regardless of whether LSG was done. Diabetes remission rates of around 86% after LSG have also been reported. In this study, the percentage of full diabetes remission was 77.4%, which is somewhat lower than the previous report but not by much. The current study found that 63.5% of patients in the medical treatment group and 80.3% of subjects in the LSG group had normal albuminuria. Weight reduction associated negatively with the change in the log UACR in both the medical treatment and LSG groups in the analysis of the remaining individuals with microalbuminuria and macroalbuminuria. The medical treatment group had a greater number of individuals with microalbuminuria and macroalbuminuria, which was unexpected.
In conclusion, medical treatment may not produce the necessary weight reduction to ameliorate albuminuria, and bariatric surgery, particularly LSG, may be the preferable technique to accomplish enough weight loss.
