OBJECTIVE This study aims to investigate the etiological relationship among hepatitis B virus (HBV), hepatitis C virus (HCV), and alcohol as risk factors in a cohort of hepatocellular carcinoma (HCC) patients from India. The clinical and biochemical profiles and tumor characteristics in the HCC cases were also evaluated. METHODS A total of 357 consecutive(More)
OBJECTIVE Our aim was to evaluate whether the association of GSTM1/T1 gene polymorphisms modifies the risk of Hepatocellular carcinoma (HCC) and what is its correlation with other predisposing risk factors like alcohol intake, cigarette smoking and hepatitis B and C infections. STUDY DESIGN/SETTING It was a case-control study, included 254 HCC cases(More)
OBJECTIVES The study was designed to characterize the surface, core promoter, precore/core region sequences for the presence of mutations in hepatitis B virus (HBV) associated with different liver diseases. METHODS 567 HBV associated patients with different liver diseases were enrolled in this study. All samples were analyzed for HBV surface, core(More)
BACKGROUND & OBJECTIVES Hepatitis E is the main cause of enterically transmitted non-A, non-B hepatitis in developing countries. In the developed countries such as the USA, Japan and Taiwan, the viruses infecting humans and swine share the same genotype with a high sequence similarity. Genotype 1 circulates in humans whereas genotype 4 in pigs in India. The(More)
BACKGROUND Hepatitis A virus is an infection of liver; it is hyperendemic in vast areas of the world including India. In most cases it causes an acute self limited illness but rarely fulminant. There is growing concern about change in pattern from asymptomatic childhood infection to an increased incidence of symptomatic disease in the adult population. (More)
Hepatitis E virus (HEV) is evolving as a major global threat to public health, including in developed countries. We partially sequenced the ORF 2 capsid protein genes of HEV genomes from patients with acute liver failure, including pregnant women in the northern part of India. Five unique synonymous substitutions and one non-synonymous substitution, along(More)
Northeast India is known for the demographic heterogeneity of its tribal population, but there is no information about hepatitis C virus infection and associated risk factors. Anti-HCV was measured, HCV-RNA was detected based on the 5’ UTR-core region, and genotyping was done by direct sequencing of the NS5b region. Antibodies to HCV were found in 13.7 % of(More)
BACKGROUND & OBJECTIVES Chronic hepatitis B is an important cause of morbidity and mortality. We conducted a study comparing the efficacy of adefovir and lamivudine with respect to their impact on serum and hepatic viral DNA clearance, and improvement in hepatic necro-inflammatory score, in naive patients of chronic hepatitis B. METHODS This prospective(More)
