background chronic hepatitis b is one of the most common causes of cirrhosis and hepatocellular toxicity in many countries, including iran. cytotoxic t lymphocyte (ctl) and natural killer (nk) cells are the two of main cell populations considered as cytotoxic cells. one of the distinct pathways ctl and nk cells exert cytotoxicity is perforin/granzyme. after the cytotoxic cell/target cell juncti...

conclusions office workers with chronic hepatitis c, treated with pegylated-interferon-α2b plus ribavirin, had work performance loss. in subjects treated with acetyl-l-carnitine supplementation we observed increased daily activity and reduced presenteeism and fatigue. acetyl-l-carnitinegroup had a smaller reduction of productivity comparing to placebo group. results significant difference were ...

abstract background: combination therapy with interferon and ribavirin is the most effective treatment for chronic hepatitis c today. the aim of this study was to evaluate the efficacy and safety of thrice-weekly heberon (interferon alfa-2b) in combination with ribavirin as first -line treatment of chronic hepatitis c. methods: a total of97 treatment-naive patients received heberon three millio...

conclusions this study found that gbv-c infection has a high frequency among injecting drug users with hiv/hcv coinfection and hcv mono-infection in yunnan, china. in patients with chronic hepatitis c and hiv coinfection, gbv-c rna was associated with significantly lower alt and ast levels, suggesting a beneficial effect of gbv-c infection on chronic hepatitis c. results gbv-c rna was identifie...

Background and Aims: Chronic hepatitis C is one of the most important etiologies of cirrhosis and hepatocellular carcinoma worldwide. Clinical condition of hepatic patients and the outcome of chemotherapy are under impact of Hepatitis C virus (HCV) genotypes. Therefore, HCV genotyping is important for prediction of success of chemotherapy and progression of liver diseases. Methods: In thi...

conclusions to our knowledge, this is the first chronic case confirmed by the prolonged presence of hev rna in china. it is also the first reported persistent hepatitis e infection caused by hev genotype 4. case presentation here we report a chinese boy with acute lymphoblastic leukemia, who developed hepatitis e during a period of intensive chemotherapy. twenty months after the initial infecti...

conclusions these findings indicated the association of the hbsag titer and serum ifnar2 in hbsag clearance in hepatitis b virus- infected patients. in consequence, immune mechanisms related to ifn-α/β signaling might be responsible in chb outcome. background loss of hepatitis b surface antigen (hbsag) in chronic hepatitis b (chb) infection is a favorable outcome. type i interferon (ifni) has a...

Background & Aims: Hepatitis C virus (HCV) infection is a leading cause of chronic liver disease worldwide. The clearance of the HCV is dependent on cytokines control led by genetic. The purpose of this study was to investigate the impact of Lymphotoxin (LT-A) polymorphism at +252 in susceptibility to chronic hepatitis C. Methods: In this case-control study, 120 individuals infected by HCV and ...

background torque teno virus (ttv) belongs to the circoviridae family and was separated from japanese patients with elevated levels of serum alanine transferase for the first time. following this, extensive studies have been carried out around the world. objectives the present study was designed to investigate and determine the frequency of ttv genotypes in patients with chronic hepatitis b and...

BACKGROUND & OBJECTIVE The recent discovery of a novel parenterally transmitted, unenveloped, single-stranded DNA virus called TT virus (TTV) in chronic hepatitis patients with unclear pathogenesis throughout the world led us to investigate, its presence in chronic hepatitis patients attending a hospital in New Delhi, India, and to evaluate its role in liver disease. METHODS TT virus DNA was ...
