| Research Abstract |
The review of the the pathological data of a total of 996 patients autopsied in Oku-Komyo-En(1940-1999) found that the dramatic increase in the incidence of cirrhosis of the liver and HCC(1960-1999). In patients with cirrhosis of the liver, total RNA was examined by nested RT-PCR. The HCV genotypes were 85.7% for 1b(30/35), and 14.3% for 2a(5/35) in patients with leprosy. Tissues of 30 patients with leprosy(HCV genotype 1b) were amplified in 12 of the samples(NS5B region). Recombinant clones were then sequenced and the phylogenetic analysis of NS5 sequences was carried out. Our data suggest that at least three strains of HCV existed in this sanatorium. This observation strongly suggests the horizontal transmission of HCV in the past 70 years in this leprosy sanatorium.
