AIM:To investigate the effect of transjugular intra-hepatic porto-systemic shunt (TIPS) on malnutrition in portal hypertensive cirrhotic patients.METHODS: Twenty-one patients with liver cirrhosis and clinical indications for TIPS insertion were investigated before and 1, 4, 12, 52 wk after TIPS. For each patient we assayed body composition parameters [dry lean mass, fat mass, total body water (TBW)], routine liver and kidney function tests, and free fatty acids (FFA). Glucose and insulin were measured for the calculation of the homeostasis model assessment insulin resistance (HOMA-IR); liver function was measured by the galactose elimination capacity (GEC); the severity of liver disease was graded by model for end-stage liver disease (MELD).RESULTS: Porto-systemic gradient decreased after TIPS (6.0±2.1 mmHg vs 15.8±4.8 mmHg, P<0.001). Patients were divided in two groups according to initial body mass index. After TIPS, normal weight patients had an increase in dry lean mass (from 10.9±5.9 kg to 12.7±5.6 kg, P=0.031) and TBW (from 34.5±7.6 L to 40.2±10.8 L,P=0.007), as well as insulin (from 88.9±49.2 pmol/L to 164.7±107.0 pmol/L,P=0.009) and HOMA-IR (from 3.36%±2.18% to 6.18%±4.82%,P=0.023). In overweight patients only FFA increased significantly (from 0.59±0.24 mmol/L to 0.93±0.34 mmol/L, P=0.023).CONCLUSION: TIPS procedure is effective in lowering portal pressure in patients with portal hypertension and improves body composition without significant changes in metabolic parameters.
