| Research Abstract |
We investigated the clinical meaning of SNP analysis in 1) difference between NASH and simple steatosis, 2) fulminant hepatitis, 3) effect,of IFN therapy in hepatitis C virus.
1) The carrier frequencies of polymorphisms at positions -1031 C and -863 A were significantly higher in patients with NASH than in those with simple steatosis. TNF polymorphisms, which influence TNF production and insulin resistance, might be associated with the progression of NAFLD. 2) The carrier rate with both IL-10 haplotype and TNF-β gene B2/B2 was significantly higher than control. Variations of cytokine polymorphisms including IL-10 and TNF-β genes may be attributable to the pathogenesis of FH. 3) In TNF-β gene polymorphism, B2/B2 frequency was significantly increased in non-responder, compared with transient responder and sustained responder. Serotype, liver fibrosis and TNF-β gene polymorphism might be associated with non-responders to the combined therapy.
