Infections ACLF Death Different clinical courses of acutely decompensated cirrhosis Pre-ACLF Unstable decompensated cirrhosis Stable decompensated cirrhosis 0 90 180 270 360 Days Highlights Patients with acutely decompensated cirrhosis without ACLF develop 3 different clinical courses. Patients with pre-ACLF develop ACLF within 90 days and have high systemic inflammation and mortality. Patients with unstable decompensated cirrhosis suffer from complications of severe portal hypertension. Patients with stable decompensated cirrhosis have less frequent complications and lower 1-year mortality risk.

Important progress has been made recently regarding the pathogenesis and treatment of hepatorenal syndrome (HRS). However, scant information exists about factors predicting outcome in patients with cirrhosis and HRS. Moreover, the prognostic value of the model of end-stage liver disease (MELD) score has not been validated in the setting of HRS. The current study was designed to assess the prognostic factors and outcome of patients with cirrhosis and HRS. The study included 105 consecutive patients with HRS. Forty-one patients had type 1 HRS, while 64 patients had type 2 HRS. Patients with type 1 HRS not only had more severe liver and renal failure than type 2 patients, they also had greater impairment of circulatory function, as indicated by lower arterial pressure and higher activation of vasoconstrictor factors. In the whole series, the median survival was 3.3 months. In a multivariate analysis of survival, only HRS type and MELD score were associated with an independent prognostic value. All patients with type 1 HRS had a high MELD score (>20) and showed an extremely poor outcome (median survival: 1 mo). By contrast, the survival of patients with type 2 HRS was longer and dependent on MELD score (>20, median survival 3 mo; <20, median survival 11 mo; P < .002). In conclusion, the outcome of patients with cirrhosis and HRS can be estimated by using two easily available variables, HRS type and MELD score. These data can be useful in the management of patients with HRS, particularly for patients who are candidates for liver transplantation. (HEPATOLOGY 2005;41:1282-1289

The present study was designed to determine the seroprevalence of hepatitis B and C virus (HBV, HCV) infections and risk factors in the Turkish general population. Participants were enrolled from urban and rural areas of the predetermined 23 EUROSTAT NUTS 2 region. A two-stage stratified sampling method was used to select participants from these regions (n = 5460; 50.9% females; mean (SD) age: 40.8 (14.7) years). Sociodemographics, clinical characteristics and risk factors were recorded at home visits. The seropositivity rates for hepatitis B surface antigen (HBsAg), anti-HCV, anti-HBs and anti-HBc total were 4.0%, 1.0%, 31.9% and 30.6%, respectively. Among HBsAg-positive cases, 94.5% were anti-HBe-positive, 70.2% were HBV-DNA-positive and 2.8% were anti-HDV total positive; 99.1% of HBV infections were of genotype D. Close contact with a hepatitis patient (OR 3.24; 95% CI 2.25-4.66; p < 0.001), living in the southeastern region (OR 2.74; 95% CI 1.7-4.45; p < 0.001), male gender (OR 1.77; 95% CI 1.28-2.46; p < 0.001), being married (OR 1.62; 95% CI 1.02-2.57; p 0.038), educational level less than high school (OR 1.53; 95% CI 1.04-2.26; p 0.03), orodental interventions (OR 1.54; 95% CI 1.01-2.35; p 0.047) and a history of non-disposable syringe use (OR 1.4; 95% CI 1.01-1.96; p 0.045) were significant determinants of HBsAg positivity. Age ≥50 years (OR 2; 95% CI 1.09-4.3; p 0.026) was the only significant predictor of anti-HCV positivity. In conclusion, our findings revealed an HBsAg positivity in 4% and anti-HCV positivity in 1% of the adult population and at least one-third of the population has been exposed to HBV infection in Turkey.

Serum FGF21 levels are increased in patients with NAFLD regardless of potential confounders and represent an independent predictor of liver steatosis. These findings support further investigation of this molecule in metabolic liver diseases.

Our results suggest that serum omentin levels are raised in patients with NAFLD regardless of potential confounders and represent an independent predictor of hepatocyte ballooning.
