By PCR screening, we found an extremely high prevalence of TT virus (TTV) in the general populations from different geographic regions. This suggests that TTV may be a common DNA virus with no clear disease association in humans. TTV genotyping by phylogenetic analysis was also performed.
BACKGROUND Molecular studies have demonstrated that the hepatitis C virus (HCV) genotype and host genetics play predictive roles in the management of patients infected with HCV. OBJECTIVES This study aimed to investigate the HCV genotype, core amino acid (aa) 70 substitution, and polymorphisms near the IFNL3 gene (including rs12979860 and rs8099917) among Iranian patients with chronic hepatit...
context there is growing evidence that interferon lambda 4 (ifnl4) polymorphism is related to sustained virological response (svr) in hepatitis c virus (hcv) infection. we analyzed the relationship between ifnl4 (rs368234815) polymorphism and svr in dual- and triple- therapy in hcv genotype 1, 2, 3 and 4 infected asian, caucasian and african patients. conclusions favorable ifnl4 rs368234815 gen...
Background TT virus (TTV) hepatitis is an infectious disease which can have both hepatic and extrahepatic manifestations, and it is transmitted prevalently parenterally, and rarely by enteral way. The prevalence of TTV in donors in the USA is 1%, from 1.9-10% in Great Britain, in Japan 12%, in Thailand 7-30%, in Russia 10-20%, and in Brazil 62%. In patients with cryptogenic cirrhosis, the TTV w...
TT virus (TTV) is a recently discovered infectious agent originally obtained from transfusion-related hepatitis. However, the causative link between the TTV infection and liver disease remains uncertain. Recent studies demonstrated that genome sequences of different TTV strains are significantly divergent. To assess genetic heterogeneity of the TTV genome in more detail, a sequence analysis of ...
The goal of present study was to investigate the relationship between polymorphisms of TGF-β1 and familial aggregation of liver cancer in Guangxi Zhuang, Han, and Yao populations. We conducted a population-based case-control family study of liver cancer in Guanxi, China. A total of 214 individuals from 37 case families were surveyed for polymorphisms in TGF-β1. We genotyped six functional TGF-β...
OBJECTIVE Two polymorphisms in the promoter region of the gene encoding cytosolic aldehyde dehydrogenase (ALDH1A1), ALDH1A1*2 and ALDH1A1*3, have recently been identified. The present study sought to determine whether an association exists between ALDH1A1 genotypes, alcohol dependence, drinking history, and liver function tests in the two major ethnic groups of Trinidad and Tobago (TT). METHO...
