Resumo: |
Purpose: Bariatric surgeries reduce non-alcoholic fatty liver disease (NAFLD), which is associated with metabolic syndrome co-morbidities; however, the effects of duodenal-jejunal bypass (DJB) have not been investigated. This study aimed to evaluate the effects of DJB on serum and hepatic profiles of obese rats fed on a western diet (WD). Methods: Male Wistar rats were fed a standard rodent chow diet (CTL group) or WD ad libitum. After 10 weeks, WD rats were submitted to sham (WD SHAM) or duodenal-jejunal bypass (WD DJB). Body weight, fat pad depots, glycemia, insulinemia, HOMA-IR, TyG, lipids profile and hepatic analyses were evaluated two months after surgery. Results: The WD SHAM group presented greater obesity, hyperglycemia, hyperinsulinemia, insulin resistance, hypertriglyceridemia and hepatic steatosis than the CTL group. WD DJB rats presented decreased serum glucose and insulin resistance, when compared to WD SHAM animals, without changes in insulinemia. In addition, DJB surgery normalized serum TG and attenuated TG accumulation and steatosis in the liver of the WD DJB group. Hepatic ACC and FAS protein expressions were similar in all groups. Conclusions: DJB attenuates hepatic parameters of NAFLD in obese rats fed on a WD diet |
