BACKGROUND Recent studies have associated non-alcoholic fatty liver disease (NAFLD) with increased risk of cardiovascular disease, using tests of subclinical atherosclerosis. AIM To evaluate the influence of NAFLD on subclinical atherosclerosis and coronary artery disease (CAD). METHODS We reviewed Pubmed and EMBASE. According to inclusion and exclusion(More)
Abnormal liver biochemical tests are present in up to 30% of patients with inflammatory bowel disease (IBD), and therefore become a diagnostic challenge. Liver and biliary tract diseases are common extraintestinal manifestations for both Crohn's disease and ulcerative colitis (UC), and typically do not correlate with intestinal activity. Primary sclerosing(More)
Tissue fibrosis is a core pathologic process that contributes to mortality in ~45% of the population and is likely to be influenced by the host genetic architecture. Here we demonstrate, using liver disease as a model, that a single-nucleotide polymorphism (rs12979860) in the intronic region of interferon-λ4 (IFNL4) is a strong predictor of fibrosis in an(More)
BACKGROUND & AIMS Minimal hepatic encephalopathy (MHE) is associated with falls, traffic accidents, and overt HE. However, the association with survival is controversial. We assessed the effects of MHE on the long-term survival of patients with cirrhosis. METHODS We performed a prospective study of 117 consecutive patients with cirrhosis seen at a(More)
AIM To investigate the influence of metformin use on liver dysfunction and hepatic encephalopathy in a retrospective cohort of diabetic cirrhotic patients. To analyze the impact of metformin on glutaminase activity and ammonia production in vitro. METHODS Eighty-two cirrhotic patients with type 2 diabetes were included. Forty-one patients were classified(More)
BACKGROUND & AIM This study assessed the involvement of metabolic factors (anthropometric indices, insulin resistance (IR) and adipocytokines) in the prediction of portal hypertension, esophageal varices and risk of variceal bleeding in cirrhotic patients. MATERIAL AND METHODS Two prospective and retrospective cohorts of cirrhotic patients were selected(More)
Hepatitis C virus (HCV) genotypes 2 and 3 have previously been classified as easy-to-treat genotypes, because sustained virologic responses (SVRs) up to 80% have been achieved with 24-week peginterferon and ribavirin. More detailed studies have shown differences between HCV genotypes 2 and 3, indicating that genotype 3 has become the most difficult-to-treat(More)
BACKGROUND A Cochrane meta-analysis established that pegylated interferon α-2a is more effective than peginterferon α-2b in terms of sustained virological response (SVR) in the treatment of chronic hepatitis C. Rapid virological response (RVR) and early virological response (EVR) are crucial to reach SVR and to make clinical decisions. AIM To compare RVR(More)
Hepatocellular carcinoma is the third leading cause of cancer-related deaths in the world. It is associated with an important mortality rate and the incidence is increasing. Patients showing metabolic syndrome seem to have higher incidence and mortality rates from hepatocellular carcinoma than healthy subjects, especially those with type 2 diabetes mellitus(More)
AIM Evaluate the association between phase angle and the development of hepatic encephalopathy in the long-term follow-up of cirrhotic patients. METHODS This was a prospective cohort study. Clinical, nutritional and biochemical evaluations were performed. Mann-Whitney's U and χ2 tests were used as appropriate. Kaplan-Meier curves and Cox proportional(More)
