UNLABELLED The widely accepted interleukin-28B (IL-28B) rs12979860 C/T polymorphism and the more recently proposed vitamin D serum concentration are two novel predictors of the response to antiviral treatment in chronic hepatitis C virus (HCV) infection. This study aimed to verify whether the IL-28B rs12979860 C/T polymorphism and pretreatment serum vitamin(More)
BACKGROUND & AIMS A single nucleotide polymorphism (rs12979860 C/T) 3kb upstream of the interleukin 28B (IL-28B) gene was shown to be associated with hepatitis C clearance. We verified whether this association also translates into a different genotype distribution at the end of the disease trajectory. METHODS A RFLP-PCR technique was used to genotype 412(More)
This study aimed to determine whether the single-nucleotide polymorphism (rs12979860 C/T) of the interleukin 28B (IL-28B) gene, which is associated with hepatitis C virus (HCV) clearance, is also associated with fibrosis in chronic HCV infection. An RFLP-PCR technique was used to genotype 629 HCV-positive patients (200 with cirrhosis) and 428 healthy(More)
UNLABELLED Vitamin D deficiency seems to predict the unsuccessful achievement of sustained viral response (SVR) after antiviral treatment in hepatitis C virus (HCV) difficult-to-treat genotypes. Vitamin D binding protein (GC) gene polymorphisms are known to influence vitamin D levels. This study was performed to assess whether the interaction between basal(More)
BACKGROUND AND AIM The PNPLA3 rs738409 C>G polymorphism has been found to be strongly associated with non-alcoholic fatty liver disease and with alcoholic liver disease. Whether the PNPLA3 rs738409 polymorphism could be a risk factor for the development of hepatocellular carcinoma (HCC) in cirrhosis patients is unknown. METHODS This study included 483(More)
AIM To assess the relationship between vitamin D receptor (VDR) gene polymorphisms and the presence of hepatocellular carcinoma (HCC). METHODS Two-hundred forty patients who underwent liver transplantation were studied. The etiologies of liver disease were hepatitis C (100 patients), hepatitis B (37) and alcoholic liver disease (103). A group of 236(More)
BACKGROUND A single nucleotide polymorphism (SNP) C677T in the methylenetetrahydrofolate reductase (MTHFR) gene has been identified. The TT or CT genotypes show a marked reduction of the enzyme activity; this causes higher homocysteine levels and alterations of folate metabolism. Folate metabolism is essential for DNA synthesis and methylation, crucial(More)
This study was designed to establish whether the measurement of apparent diffusion coefficients (ADCs) is clinically accurate in diagnosing liver fibrosis in a selected series of cirrhotic patients. Twenty-eight cirrhotic patients (mean age 58.1 years) with histologically proven liver fibrosis and 29 healthy controls (mean age 43.8 yeas) underwent liver(More)
OBJECTIVE To investigate whether interleukin-6 (IL-6) polymorphisms could be associated with the occurrence of hepatocellular carcinoma (HCC) in patients with liver cirrhosis and whether this influence could act synergistically with the gender of the patient. METHODS We studied 219 consecutive patients who underwent liver transplantation for liver(More)
In immune-competent patients, higher vitamin D levels predicted sustained viral response (SVR) following interferon (INF) and ribavirin therapy for chronic hepatitis C. This study aimed to verify the influence of vitamin D serum levels and/or vitamin D supplementation in predicting SVR rates for recurrent hepatitis C (RHC). Forty-two consecutive patients(More)
