Body composition changes after transjugular intrahepatic portosystemic shunt in patients with cirrhosis
AIM: To investigate the effect of transjugular intrahepatic 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

The effect of antioxidant supplementation on hepatitis C viral load, transaminases and oxidative status: a randomized trial among chronic hepatitis C virus-infected patients
Objective To assess the effect of antioxidant supplementation on hepatitis C viral load, transaminases and oxidative status. Methods We performed a randomized, placebo-controlled, double-blind trial to assess the effect of antioxidant supplementation on serum alanine aminotransferase, plasma hepatitis C viral load as well as oxidative and antioxidant markers in patients with hepatitis C virus infection. The participants received a daily dose of ascorbic acid (500 mg), D-alpha-tocopherol (9451 U) and selenium (200 mu g) or placebo tablets for 6 months. Results Twenty-three patients were included. During supplementation, the antioxidant group had significantly higher levels of plasma ascorbic acid and a-tocopherol than the placebo group and the activity of erythrocyte glutathione peroxidase had significantly increased from baseline to month 6. No differences were observed in serum alanine aminotransferase and logo-transformed plasma hepatitis C virus-RNA between the groups or changes from the baseline at any time. No consistent differences between groups or changes from the baseline with respect to erythrocyte activities of antioxidative enzymes (glutathione reductase, superoxide dismutase and catalase) or plasma levels of oxidative markers (malondialdehyde and 2-amino-adipic semialdehyde) were found. Conclusion Supplementation with vitamin C, E and selenium increased the antioxidant status, but had no effects on alanine aminotransferase, viral load or oxidative markers

Alcohol consumption and liver cirrhosis mortality: New evidence from a panel data analysis for sixteen European countries
Empirical evidence gives strong support to a close association between liver cirrhosis mortality and the intake of alcohol and most often a log-linear relationship is assumed in the econometric modeling. The present analysis investigates for unit roots in a panel data set for sixteen European countries – covering the period 1970-2006 - where both alcohol consumption and liver cirrhosis seem best described as trend-stationary variables. Therefore a fixed effects model including individual trends is applied in the analysis but also a more flexible non-linear functional form with fewer restrictions on the relationship between liver cirrhosis mortality and alcohol consumption is included. The conclusion is that the total level of alcohol consumption as well as the specific beverages – beer, wine and spirits – contributes to liver cirrhosis mortality, but the present study also reveals that directly addressing the question of panel unit roots and in this case subsequently applying a trend-stationary modeling methodology reduces the estimates of the impacts from alcohol consumption to liver cirrhosis. Finally, more restrictive alcohol policies seem to have positively influenced the country-specific development in cirrhosis mortality.Alcohol consumption; Liver cirrhosis mortality; Trend-stationary panel data; Non-linear modelling

Development and validation of a prognostic score to predict mortality in patients with acute on chronic liver failure.
Background & Aims. Acute-on Chronic Liver Failure (ACLF) is a frequent syndrome (30% prevalence) characterized by acute decompensation of cirrhosis, organ failure(s) and high short-term mortality. This study develops and validates a specific prognostic score for ACLF patients.
Methods. Data from 1,349 patients included in the CANONIC study were used. First, a simplified organ function scoring system (CLIF-Consortium Organ Failure score, CLIF-C OFs) to diagnose ACLF was developed using data from all patients. Subsequently, in 275 patients with ACLF, CLIF-C OFs and two other independent predictors of mortality (age and white-cell count) were combined to develop a specific prognostic score for ACLF (CLIF CONSORTIUM score for ACLF, CLIF-C ACLFs). Concordance index (C-index) was used to compare the discrimination abilities of CLIF-C ACLFs, MELD (MELDs), MELD-Sodium (MELD-Nas) and Child-Pugh (CPs) scores. CLIF-C ACLFs was validated in an external cohort and assessed for sequential use.
Results. CLIF-C ACLFs showed a significantly higher predictive accuracy than MELDs, MELD-Nas and CPs, reducing (19-28%) the corresponding prediction error rates at all the main time-points after ACLF diagnosis (28, 90, 180 and 365 days) in both the CANONIC and the external validation cohort. CLIF-C ACLFs computed at 48 hours, 3-7 days and 8-15 days after ACLF diagnosis predicted 28-day mortality significantly better than at diagnosis.
Conclusions. CLIF-C ACLFs at ACLF diagnosis is superior to MELDs and MELD-Nas in predicting mortality. CLIF-C ACLFs is a clinically relevant, validated scoring system that can be used sequentially to stratify the risk of mortality in ACLF patients
