About
Bariatric-metabolic surgery is effective in treating the cluster of conditions forming the metabolic syndrome, strictly associated with NAFLD and NASH. Recently, we and other authors have shown also in the long term (up 5 years) with randomized-controlled trials (RCTs) that bariatric-metabolic surgery allows remission of type 2 diabetes and obesity reduction, which are the two major pathogenetic factors of NASH development, with maintenance of weight loss.
Few small and mainly retrospective studies have shown that bariatric surgery is effective in improving NASH histologic picture in obese subjects.
The aim of our proposal is to conduct a 3 arm single centre, superiority, RCT comparing Roux-en-Y Gastric Bypass (RYGB) with Sleeve Gastrectomy (SG) and with Intensive Lifestyle Modifications (ILM) for the treatment of Non-Alcoholic Steato-Hepatitis.
Full description
This is a Randomized Controlled multicentre Trial involving the Catholic University (Professor Geltrude Mingrone as PI and Professor Marco Raffaelli as co-PI)
The research question in PICOT format (P) - Population: Adults 25 to 70 years of age and BMI ≥ 30 and ≤55 kg/m2 with histological diagnosis of NASH.
(I) - Intervention: Roux-en-Y Gastric Bypass or Sleeve Gastrectomy, both plus lifestyle counseling.
(C) - Comparison: Intensive Lifestyle Modifications. (O) - Outcome: the histological resolution of NASH without worsening of fibrosis at 1 year after the interventions.
(T) - Time: One year after the intervention started.
1.3.3.2 Research Goals
The liver biopsy will be performed at baseline and at 1 year follow-up. Another liver biopsy will be performed at 3 and 5 years follow-up.
