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)
A genome-wide association screen for primary biliary cirrhosis risk alleles was performed in an Italian cohort. The results from the Italian cohort replicated IL12A and IL12RB associations, and a combined meta-analysis using a Canadian dataset identified newly associated loci at SPIB (P = 7.9 x 10(-11), odds ratio (OR) = 1.46), IRF5-TNPO3 (P = 2.8 x(More)
UNLABELLED The incidence of hepatocellular carcinoma (HCC) is increasing in Western countries. Although several clinical factors have been identified, many individuals never develop HCC, suggesting a genetic susceptibility. However, to date, only a few single-nucleotide polymorphisms have been reproducibly shown to be linked to HCC onset. A variant(More)
BACKGROUND/AIMS To understand the intrafamilial transmission and the existing risk factors related to HCV infection in subjects confirmed anti-HCV positive, their sexual partners and household contacts in Friuli, North-East Italy. METHODS We enrolled all the subjects that were consecutively identified as HCV positive during routine laboratory testing in(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)
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)
The course of hepatitis C virus (HCV) infection carriers with normal/near-normal aminotransferases (NALT) is usually mild; however, in a few, fibrosis progression occurs. We aimed to verify whether monitoring by liver biopsy might be replaced by noninvasive methods and to identify factors associated with fibrosis progression in patients with persistently(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)
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)
