Overweight/obesity is increasing both in the general population and in patients with cirrhosis. In compensated patients with cirrhosis increased BMI is a risk factor for clinical decompensation independent of liver function and portal pressure. Nonetheless, patients with cirrhosis and obesity show a progressive increase in portal pressure, which might explain their increased risk of complications. Since obesity is a potentially modifiable risk factor, we designed this proof-of-concept study to assess the effects of weight loss (obtained by 4 months of diet and exercise) on portal pressure in patients with compensated cirrhosis and overweight/obesity.

Inclusion Criteria: - Age: 18-75 years - Compensated liver cirrhosis (diagnosed by biopsy or clear clinical, laboratory and imaging data), of any etiology; patients who presented decompensation due to gastroesophageal variceal hemorrhage can also be included if hemorrhage a) occurred > 3 months before inclusion AND b) has been treated with drugs+band ligation AND c) no other decompensations occurred simultaneously. - HVPG > 5 mmHg - BMI > 26 Kg/m2 - Absence of gastroesophageal varices or small esophageal varices OR large varices only if the patient is already on treatment with beta-blockers since at least 6 weeks. - In case of presence of systemic arterial hypertension and/or diabetes, patients can be included if the treatment of these condition is stable for at least 3 months Exclusion Criteria: |

Type | Measure | Description | Time frame | Safety issue |
---|---|---|---|---|
Primary | HVPG change | The effects of weight loss on portal pressure will be assessed by measuring the HVPG at baseline and after 4 months of diet+exercise in the included patients. | 4 months | No |
Secondary | Hepatic function | The effects of weight loss on liver function will be estimated by assessing standard liver tests and indocyanine green clearance at baseline and after 4 months of diet+exercise | 4 months | Yes |
Secondary | Serum markers of fibrosis, angiogenesis, endothelial dysfunction and oxidative stress | The effects of weight loss on Serum markers of fibrosis, angiogenesis, endothelial dysfunction and oxidative stress will be assessed by extracting adequate blood samples at baseline and after 4 months of diet+exercise | 4 months | No |
Secondary | Body adiposity changes | Changes in BMI and body fat% will be assessed by measuring body weight and % of fat at baseline and after 4 months of diet + exercise. | 4 months | No |
