Abstract
Hepatitis B virus (HBV) is characterized with high mutations, which is attributed to the lack of proof-reading of the viral reverse transcriptase and host immune pressure. In this study, 31 HBV chronic carriers from 14 families were enrolled to investigate the evolution of the same original HBV sources in different hosts. Sequences of pre-C and C (pre-C/C) genes were analyzed in eight pairs of HBV-infected mothers with longitudinal sera (at an interval of 6.0-7.2 years) and their children (5.5-6.7 years old), and in 15 adults (21-78 years old) from six families with known intrafamilial HBV infection. The pre-C/C sequences had almost no change in eight mothers during 6.0-7.2 years and their children who were in immune tolerant phase. The pre-C/C sequences from the 15 adults of six families, mostly in the immune-clearance phase or the low replicative phase, showed various diversified mutations between individuals from each family. Compared to a reference stain (GQ205441) isolated nearby, the pre-C/C in individuals in immune tolerant phase showed 98.56%-99.52% homology at nucleotide level and 99.5%-100% homology at amino acid level. In contrast, multiple mutations were developed in the immune-clearance phase or the low replicative phase, affecting immune epitopes in core gene and G1896 in pre-C gene. The results indicate that the evolution of new HBV variants is not mainly resulted from the spontaneous error rate of viral reverse transcription, but from the host immune pressure.

[PMID: 26723531 DOI: 10.1016/j.jtbi.2015.12.005] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/01/2015] [Revised: 11/30/2015] [Accepted: 12/01/2015] [Indexed: 12/12/2022]
Abstract
Hepatitis B virus (HBV) dynamics in treated patients can be complex and differ considerably from other viral infections. We analyse dynamics of liver and serum levels of HBV DNA in 24 chronically HBV-infected individuals undergoing 1 year of combination therapy with pegylated interferon alpha and adefovir dipivoxil (ADV), followed by 2 years of ADV monotherapy. Serum viral dynamics differentiated the patients into four response groups dependent on how quickly viremia became undetectable: quickly suppressed (HBV DNA <100 copies/ml within 8 weeks and staying suppressed, GRP1); quickly suppressed but some rebound (<10,000 copies/ml, GRP2); slow decay (GRP3); virological failures (>10,000 copies/ml, GRP4). These groups did not differ before start of therapy by serum HBV DNA (p=0.2), HBsAg (p=0.1), ALT (p=0.4), total HBV DNA within the liver (p=0.08), or cccDNA (p=0.3). Despite very different serum HBV DNA levels after 3 years, there was no statistical difference in total HBV DNA within the liver (p=0.08), nor in cccDNA levels (p=0.1), but HBsAg levels in serum were significantly lower for GRP1 compared to GRP4 (p=0.02). Efficacy in terms of reduction over the 3 years of serum HBV DNA, liver HBV DNA, cccDNA, and ratios of liver HBV DNA to cccDNA were 99.98%, 99.5%, 98.4%, and 83.2% respectively, exhibiting larger antiviral effects in serum than in liver. Over the course of therapy, HBV DNA viremia exhibited large oscillations for some individuals. Mathematical modelling reproduced the dynamics of these diverse groups by assuming a number of viral clones arose that experienced delayed recognition by the antibody response. Large viremia oscillations under therapy suggest sequential outgrowth of viral clones with delayed recognition by the humoral response.

Differences in serum microRNA profiles in hepatitis B and C virus infection. J Infect 2014; 70:273-87. [PMID: 25452043 DOI: 10.1016/j.jinf.2014.10.017] [Citation(s) in RCA: 48] [Impact Index Per Article: 4.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/11/2014] [Revised: 09/18/2014] [Accepted: 10/17/2014] [Indexed: 12/22/2022]
Abstract
OBJECTIVES Patients infected with chronic hepatitis B virus (HBV) or hepatitis C virus (HCV) are at greater risk of cirrhosis and hepatocellular carcinoma. The objective of this study was to identify virus-specific serum microRNA profiles associated with liver function and disease progression. Microarray analysis of serum microRNAs was performed using the Toray 3D array system in 22 healthy subjects, 42 HBV patients, and 30 HCV patients. Selected microRNAs were then validated by qRT-PCR in 186 HBV patients, 107 HCV patients, and 22 healthy subjects. RESULTS Microarray analysis showed up-regulation of a number of microRNAs in serum of both HBV and HCV patients. In qRT-PCR analysis, miR-122, miR-99a, miR-125b, miR-720, miR-22, and miR-1275 were up-regulated both in HBV patients relative to healthy subjects, and all except miR-1275 were up-regulated in HBeAg-positive patients relative to HBeAg-negative patients. Specific microRNAs were independently associated with different aspects of HBV infection. MiR-122 was independently associated with HBV DNA level, whereas miR-125b was independently associated with levels of HBV DNA, HBsAg, and HBeAg. MiR-22 and miR-1275 were independently associated with serum γ-glutamyl transpeptidase levels. CONCLUSIONS Serum microRNA levels reflect differences in the etiology and stage of viral hepatitis.
