Liver-related and extrahepatic events in patients with non-alcoholic fatty liver disease: a retrospective competing risks analysis.
Background & Aim: Non-alcoholic fatty liver disease (NAFLD), and especially fibrotic non-alcoholic steatohepatitis, is associated with high risks of liver-related events (LRE) and extrahepatic events (EHE). We evaluated the competitive risk occurrence of LRE and EHE in a large cohort of biopsy-proven NAFLD stratified according to baseline severity of fibrosis. Methods: Two thousand one hundred thirty-five patients with biopsy-proven NAFLD were enrolled. Observed cumulative incidence functions (CIFs) were used to evaluate the risk of LRE and EHE; cause-specific Cox model and predicted CIFs were fitted to identify predictors of LRE and EHE. A replication cohort of NAFLD patients with live…
Predicting survival in patients with hepatocellular carcinoma treated by transarterial chemoembolisation
Background Transarterial chemoembolisation (TACE) is first-line treatment in unresectable hepatocellular carcinoma (HCC) and rescue treatment after failure of radical treatments in early stage HCC. Prognostic tools for HCC using time-fixed Cox models may be unreliable in patients treated with TACE because time-varying predictors interact. Aim To explore time-dependent variables as survival predictors in patients with HCC receiving TACE as first-line or second-line treatment. Methods Eighty four consecutive patients with HCC (mean age 68; male gender 62%; Child-Pugh class: A n = 73, B n = 11; Barcelona Clinic Liver Cancer class: A n = 44, B n = 24, C n = 16) treated with TACE were enrolled. …
Retreatment with pegylated interferon plus ribavirin of chronic hepatitis C non-responders to interferon plus ribavirin: A meta-analysis.
BACKGROUND/AIMS: Efficacy of retreatment with pegylated interferon (PEG-IFN) plus ribavirin of non-responders to standard or pegylated IFN plus ribavirin has been assessed in various studies, but sustained virologic response (SVR) rates are variable and factors influencing efficacy and tolerability still remain incompletely defined. We aimed to focus on SVR rates and to identify factors influencing them in this meta-analysis. METHODS: MEDLINE as well as a manual search were used. Studies were included if they were controlled or uncontrolled trials, if they had been published as full-length papers and if they included non-responders to standard or pegylated IFN and ribavirin therapy. Fourtee…

Quality-related variables at hepatological websites
Abstract Background. The amount of hepatology-related information available on the Internet has substantially increased, but little is known about the characteristics and quality of the websites. Aim. The aim of this study was to describe analytically and evaluate critically the information concerning three diseases of hepatological interest: chronic hepatitis, hemochromatosis and Caroli’s disease. Methods. In accordance with a validated method, the three search terms were entered into four English language search engines and the first five links of each were considered (a total of 60 sites). The characteristics of the websites were described and their quality was evaluated by three indepen…
La termoablazione nel trattamento delle neoplasie epatiche primitive e secondarie
Radiofrequency thermoablation is a locoregional procedure based on the use of electromagnetic waves that induce movement and consequently the production of heat. This is the basis for the coagulative necrosis produced in the tissues. The method, experimented with and developed in the '90s, is today extensively used in the treatment of focal hepatic lesions, both primary and secondary. The factors that condition the procedure are related essentially to the characteristics of the tumours and to the possibility of obtaining a predictable area of necrosis that guarantees the radicality of the treatment. As regards primary neoplasms, it should be stressed that the treatment for hepatocellular ca…
TyG index, HOMA score and viral load in patients with chronic hepatitis C due to genotype 1.
The triglycerides × glucose (TyG) index is a recently proposed surrogate marker of insulin resistance (IR), calculated from fasting plasma triglyceride and glucose concentrations. We tested the host and viral factors associated with Tyg and homeostasis model assessment (HOMA) scores, comparing their associations with histological features and with sustained virological response (SVR) in patients with genotype 1 chronic hepatitis C(G1CHC). Three hundred and forty consecutive patients with G1CHC were considered. All had a liver biopsy scored by one pathologist for staging and grading (Scheuer), and graded for steatosis, which was considered moderate–severe if ≥30%. Anthropometric and metaboli…
Visceral adiposity index is associated with histological findings and high viral load in patients with chronic hepatitis C due to genotype 1.
Metabolic factors have been associated with liver damage in patients with genotype 1 chronic hepatitis C (G1 CHC). We tested visceral adiposity index (VAI), a new marker of adipose dysfunction in G1 CHC, patients to assess its association with host and viral factors and its link to both histological findings and sustained virological response (SVR). Two hundred thirty-six consecutive G1 CHC patients were evaluated by way of liver biopsy and anthropometric and metabolic measurements, including insulin resistance (IR), homeostasis model assessment (HOMA), and VAI using waist circumference, body mass index, triglycerides, and high-density lipoprotein cholesterol. All biopsies were scored by on…

Retinol-binding protein 4 (RBP4) : a new marker of G1 HCV-induced steatosis
Il carcinoma dell'esofago
Vitamin D levels and IL28B polymorphisms are related to rapid virological response to standard of care in genotype 1 chronic hepatitis C.
BACKGROUND: Genotype 1 (G1) chronic hepatitis C (CHC) patients achieving a rapid virological response (RVR) on pegylated interferon (PEG-IFN) plus ribavirin have a high chance of sustained virological response (SVR), influenced by IL28B status, viral load, fibrosis and insulin resistance. We assessed whether 25-hydroxyvitamin D (25[OH]D) serum levels are linked to RVR and can be used together with IL28B to construct a pretreatment model to predict RVR. METHODS: A total of 117 consecutive patients with G1 CHC were evaluated by biopsy and anthropometric and metabolic measurements. 25(OH)D serum levels were measured by HPLC. IL28B rs12979860 and rs8099917 polymorphisms were also evaluated. All…

Reliability of liver stiffness measurement in non-alcoholic fatty liver disease: the effects of body mass index.
Background Liver stiffness measurement (LSM) using transient elastography (TE) is used to stage fibrosis in patients with liver disease, diagnostic reliability and the factors affecting its performance in patients with non-alcoholic fatty liver disease (NAFLD) are incompletely understood. Aim To assess LSM. Methods Consecutive NAFLD patients (n = 169), assessed by liver biopsy (Kleiner score), anthropometrical, biochemical and metabolic features, underwent LSM using TE with standard M probe. Results Liver stiffness measurement was not reliable in 23 patients (14%) due to obesity. Among patients with a reliable TE, a LSM value >7.25 kPa was the best cut-off for predicting significant fibrosi…

Hyperuricemia is associated with histological liver damage in patients with non-alcoholic fatty liver disease.
Background Hyperuricemia has been associated with metabolic disorders. In this line recent studies observed an independent link between higher uric acid serum levels and clinical diagnosis of non-alcoholic fatty liver disease (NAFLD). Aims We aimed to assess the potential association between uric acid serum levels and histological liver damage in a homogeneous cohort of biopsy-proven NAFLD patients. Methods Consecutive NAFLD patients (n = 166), assessed by liver biopsy (Kleiner score), anthropometric, biochemical and metabolic features, were included. Enzymatic colorimetric test was used for serum uric acid assays (Roche Diagnostics GmbH, Mannheim, Germany). Hyperuricemia was diagnosed when…
Transcatheter arterial chemoembolization therapy for patients with hepatocellular carcinoma: a case-controlled study.
Background & Aims: Transcatheter arterial chemoembolization (TACE) currently is used as a palliative treatment for patients with unresectable hepatocellular carcinoma (HCC), but its efficacy still is debated. Our aim was to assess the impact of TACE on patient survival and to identify prognostic factors for survival. Methods: Fifty-six cirrhotic patients with unresectable HCC undergoing at least :1 course of TACE were matched 1:1. for sex, age (in 5-year periods), parameters of Child-Pugh score, Okuda stage, and tumor type with a control group who had received only supportive care. Results: The 2 groups were comparable for cause of cirrhosis, alpha-fetoprotein serum levels, and Cancer of th…

Survival of patients with hepatocellular carcinoma in cirrhosis: a comparison of BCLC, CLIP and GRETCH staging systems
A major problem in assessing the likelihood of survival of patients with hepatocellular carcinoma (HCC) arises from a lack of models capable of predicting outcome accurately.To compare the ability of the Italian score (CLIP), the French classification (GRETCH) and the Barcelona (BCLC) staging system in predicting survival in patients with HCC.We included 406 consecutive patients with cirrhosis and HCC. Seventy-eight per cent of patients had hepatitis C. Independent predictors of survival were identified using the Cox model.One-hundred and seventy-eight patients were treated, while 228 were untreated. The observed mortality was 60.1% in treated patients and 84.9% in untreated patients. Among…

Methylenetetrahydrofolate reductase homozygosis and low-density lipoproteins in patients with genotype 1 chronic hepatitis C
Methylenetetrahydrofolate reductase status, homocysteine and lipoproteins levels have been associated with severity of disease and both rapid and sustained virological response (SVR) in patients with genotype 1 chronic hepatitis C (CHC). We aimed to assess the association of homocysteine and MTHFR status with serum cholesterol levels and their potential links to both histological findings and virological response, in patients with genotype 1 hepatitis C virus (HCV). A total of 119 consecutive patients were evaluated by biopsy and metabolic measurements. A total of 103 healthy blood donors were used as controls. Serum homocysteine and MTHFR C677T mutation were also evaluated. All patients un…
Hepatic steatosis and insulin resistance are associated with severe fibrosis in patients with chronic hepatitis caused by HBV or HCV infection.
BACKGROUND AND AIMS: Steatosis and insulin resistance (IR) are the major disease modifying in patients with chronic hepatitis C (CHC). Only few studies evaluated these features in patients with chronic hepatitis B (CHB). We aimed to assess the prevalence and the factors related to steatosis and IR in CHB patients, compared with CHC subjects, and to evaluate the potential association between these features and fibrosis severity. MATERIAL AND METHODS: One hundred and seventy consecutive patients with CHB (28 HBeAg positive, 142 HBeAg negative), were evaluated using liver biopsy and metabolic measurements and matched for sex, age and body mass index with 170 genotype 1 CHC patients. IR was def…
High risk of hepatocellular carcinoma in anti-HBe positive liver cirrhosis patients developing lamivudine resistance
The emergence of drug-resistant virus in hepatitis B virus patients treated with lamivudine is well documented. However. its clinical impact in the long-term treatment of anti-HBe positive compensated cirrhotic patients is not well known. In this study, we treated 22 consecutive patients with anti-HBe compensated cirrhosis with lamivudine for a median period of 42 months. All patients responded to lamivudine, but viral breakthrough occurred in 13 patients (59%) between 9 and 42 months of therapy due to the emergence of a mutant strain. During the follow-up, 11 developed hepatocellular carcinoma. Of these, 10 occurred soon after the emergence of viral resistance, generally showing aggressive…

Peginterferon-Α_2B plus ribavirin is more effective than peginterferon-Α_2A plus ribavirin in menopausal women with chronic hepatitis C.
Under-enrolment of women to randomized clinical trials, including chronic hepatitis C, has long been recognized. The aim of this study was to identify factors predictive of sustained virological response (SVR) to PEG IFN/Ribavirin antiviral therapy in relation to gender and reproductive status of female patients involved. Seven hundred and forty-six treatment-naïve patients (431 men, 315 women) treated with Peg-IFNα-2a (180 μg/week) or Peg-IFNα-2b (1.5 μg/kg/week) plus ribavirin (800–1400 mg/day) for 24 or 48 weeks were studied between 2006 and 2010. Differences in SVR rate, overall and by gender were assessed after adjustment and propensity score matching. SVR was obtained in 44.2% of Peg-…
