For the identification of susceptibility loci for primary biliary cirrhosis (PBC), a genome-wide association study (GWAS) was performed in 963 Japanese individuals (487 PBC cases and 476 healthy controls) and in a subsequent replication study that included 1,402 other Japanese individuals (787 cases and 615 controls). In addition to the most significant(More)
There are two subtypes of hepatitis B virus genotype A (HBV/A) and they are provisionally designated Aa ("a" standing for Africa/Asia) and Ae ("e" for Europe). In a case-control study, 78 HBV/Aa, 78HBV/Ae, and 78HBV/D carriers from several countries were compared. The prevalence of HBe antigen (HBeAg) in serum was significantly lower in carriers of HBV/Aa(More)
AIM The aim of the present study was to examine DNA methylation and histone modification changes in hepatocellular carcinomas (HCC). METHODS DNA methylation in the P16, RASSF1a, progesterone receptor (PGR) and estrogen receptor alpha (ERalpha) promoters was determined by quantitative bisulfite-pyrosequencing technique in HCC patients. Histone H3-lysine(More)
BACKGROUND Prolonged lamivudine therapy has two major problems: breakthrough hepatitis during treatment and relapse of aminotransferase (ALT) after cessation of the therapy. The aim of this study was to examine factors that could predict ALT flare after stopping lamivudine therapy. METHODS We analyzed 22 Japanese patients with chronic hepatitis B(More)
To examine the effects of polymorphisms in the gene encoding proinflammatory interleukin (IL)-1beta in patients infected with hepatitis C virus (HCV) in Japan, we studied 364 patients with chronic HCV infection (146 of whom had hepatocellular carcinoma [HCC] and 218 of whom did not) and 230 healthy control subjects. IL-1B-511 and IL-1RN genotypes were(More)
The relationship between Helicobacter pylori (H. pylori) and gastric diseases (e.g. peptic ulcer, MALT lymphoma, and stomach cancer) has been widely accepted. Recent studies have also suggested an association between H. pylori infection and idiopathic thrombocytopenic purpura (ITP). In this study, an H. pylori eradication treatment was administered to 20(More)
BACKGROUND/AIMS Although a novel DNA virus, TT virus (TTV), has been isolated from a patient with cryptogenic post-transfusion hepatitis, its pathogenic role remains unclear. To elucidate its prevalence and clinical impact in patients with liver diseases, the presence of TTV DNA was assessed in patients with liver diseases and blood donors (BDs) in Japan(More)
A 60-year-old man with a chronic hepatitis C virus (HCV) infection and histological features of chronic active hepatitis was treated with interferon-alpha (IFN). He successfully responded to IFN with normalization of serum ALT and disappearance of serum HCV-RNA. His liver biochemistry profile remained normal and serum HCV-RNA was not detected throughout the(More)
Twenty patients with unresectable hepatocellular carcinoma were treated by zinostatin stimalamer-transcatheter arterial embolization (SMANCS-TAE). After administration of SMANCS, a superselective catheterization technique was used to inject gelatin sponge particles into the artery or artery branch supplying the cancer-bearing segment. We compared the(More)

Furosemide injection was used in a total of 72 guinea pigs to induce a cochlear dysfunction similar to the sensorineural loss associated with sudden deafness. Prior to the furosemide administration, 38 of the animals were treated with an injection of one of four radio-contrast media; methylglucamine and sodium diatrizoate, sodium iothalamate,(More)
