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)
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)
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)
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)
Liver transplantation (LT) recipients are at risk for early and delayed adrenal insufficiency for multiple reasons. Although early adrenal insufficiency is known to occur in a high proportion of recipients maintained on steroid-free immunosuppressive regimens, the prevalence and risk factors associated with delayed functional adrenal gland atrophy (FAGA)(More)
PURPOSE To investigate the relevance of increasing b-values in evaluating liver fibrosis through the agreement of two diffusion-weighted (DW) sequences. MATERIALS AND METHODS A total of 29 cirrhotic patients and 29 healthy volunteers were studied on a 1.5T system. Two single-shot spin-echo echo-planar sequences were acquired using sets of increasing(More)
Primary biliary cirrhosis (PBC) is a classical autoimmune liver disease for which effective immunomodulatory therapy is lacking. Here we perform meta-analyses of discovery data sets from genome-wide association studies of European subjects (n=2,764 cases and 10,475 controls) followed by validation genotyping in an independent cohort (n=3,716 cases and 4,261(More)
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)
