Abstract

Chronic HBV and/or HCV infection can progress to liver cirrhosis and hepatocellular carcinoma (HCC) [1-4]. Among 124 hepatitis patients, 84 (67.7%) were assigned into chronic hepatitis (group 1) and 40 (32.2%) into liver cirrhosis/HCC (group 2). There was no significant difference in age between both groups. The HCV was positive in only 4 of the 15 cases, suggesting that HCV RNA was degraded in these samples, while remaining 11 cases had resolved acute HCV infection. HCV infection was found to be high in both groups (group 1 = 47.6% and group 2 = 42.5%). HCV RNA was detected in 91% of cases (100% in group 1 and 70.5% in group 2). Anti-HBc was found to be high in both groups (94% and 87.5%, respectively). Although Seroprevalence of anti-HBs was very low (12.1%) in the studied population but significantly high in group 1 (16.6%) than group 2 (P = 0.0356).. The Seroprevalence of HBsAg was equally high in both groups, that is, group 1 = 40.4% and group 2 = 42.5%, whereas DNA positivity was 70.5% and 76.4%, respectively. Overall anti-HDV Seroprevalence was 23.5%, 12 out of 51 HBsAg positive cases, relatively higher in group 2 (35.2%) compared to group 1 (17.6%) P = 0.1990. HDV viremia was detected in 83.3% of cases (100% in group 1 and 66.6% in group 2). HCV genotyping was determined as HCV genotype 2c (HCV/2c) in E1 region. A total of 7.6% of cases were un-typeable by one of either method. Overall, HCV/1b was a predominant genotype (84.6%) in Tajikistan, followed by HCV/3a (7.6%), 2a (5.7%), and 2c (1.9%). HBV genotype D (HBV/D) was the predominant genotype (94.1%) in both groups, that is, group 1 = 97% and group 2 = 88.2%, followed by genotype A (2.9% and 11.7%, respectively). HBV genotypes were determined in 45 (88%) of 51 HBsAg-positive. The full genome analysis revealed that of the four HBV/D strains, two belonged to sub genotype D1, and the remaining two to sub genotype D2. All three HBV/A strains in this study were belonged to sub genotype Ae. The results of the phylogenetic genotyping were all concordant with EIA-genotyping results (Fig.). Recent Publications: 1.
