Effect of Bariatric Surgery on Albuminuria in Non-Diabetic Non-Hypertensive Patients with Severe Obesity: a Short-Term Outcome.

BACKGROUND

Obesity is a risk factor for chronic kidney disease and albuminuria. Despite the well-documented obesity association with diabetes mellitus and hypertension, its predisposition to albuminuria is not related to these comorbidities, and, in some times, its occurrence is independent of DM or hypertension.

PURPOSE OF THE STUDY

The present study aimed to evaluate bariatric surgery effect on albuminuria in patients with severe obesity with no DM or hypertension.

MATERIALS AND METHODS

The study consisted of 137 patients with extreme obesity and albuminuria scheduled for bariatric surgery and did not have diabetes or hypertension. They underwent an assessment for 24-h urinary albumin at baseline (T0) and 6 months postoperatively (T2).

RESULTS

Albuminuria remission occurred in 83% of patients; there was a statistically highly significant difference between the baseline and the 6-month postoperative in the 24-h urinary albumin assessment. Weight loss and BMI at T2 were independent predictors of albuminuria remission.

CONCLUSION

The current work emphasizes the importance and promising role of bariatric surgery as an effective weight reduction management method in improving albuminuria, an early sign of chronic kidney disease, and a potential risk factor for cardiovascular disease.
