Interferon-α is a potent antiviral agent and a vigorous adjuvant in the induction of T-cell responses but its use is limited by hematologic toxicity. Interferon-α alters hematopoietic stem cell dormancy and impairs myelocytic and erythrocytic/megakaryocytic differentiation from hematopoietic progenitors. However, the effect of chronic interferon-α exposure on hematopoietic precursors has still ...

The susceptibility of adenovirus to the inhibitory effect of human interferons in vitro was investigated. We tested recombinant human interferons-c~2, -/~1 and -7 against adenovirus serotypes 1 and 5 (group C), 3 and 7a (group B), and a wild strain isolated from an acutely ill child who later died. Pretreatment of WISH cells with interferon-? for 24 h induced a dose-dependent inhibition of mult...

AIMS To compare interferon monotherapy with its combination with lamivudine for hepatitis B e antigen (HBeAg)-positive hepatitis B treatment. METHODS Two independent researchers identified pertinent randomized controlled trials. The trials were evaluated for methodological quality and heterogeneity. Rates of sustained virological and biochemical responses, and HBeAg clearance and seroconversi...

Interferons are proteins produced by certain cells in response to stimuli such as foreign cells (including tumour cells), bacteria, and viral antigens. They interact both with the interferon producing cells and other cells through production of effector proteins. There are three main types ofinterferons, known as (x, 1, and -y, which have direct antiviral and immunomodulatory effects. Antiviral...

Aim: To compare the frequency of thyroid disorders in patients of chronic hepatitis C being treated with interferon alpha versus pegylated interferon. Methods:: This randomized Controlled Trial was conducted at Department of Medicine, Bahawal Victoria Hospital, Bahawalpur from October 2014 to April 2015.A total of 340 diagnosed case of chronic hepatitis C by PSR HCV RNA of both genders, having ...

Human beta-interferon stimulates a 4-fold increase in the concentration of diacyglycerol and a 2-fold increase in the concentration of inositol monophosphate in Daudi (human B-lymphoblastoid) cells within 30 sec of exposure of the cells to interferon. The increase in diacylglycerol and in inositol monophosphate is transient and the concentrations of these compounds decrease to basal levels with...

 Abstract Background: Investigators were suspicious of tyrosine-methionine-aspartate-aspartate (YMDD) mutations occurred only in patients who were treated by lamivudine. However, YMDD mutations of hepatitis B virus gene (HBV DNA) in patients with chronic hepatitis B (CHB) untreated with antiviral medicines was reported in some studies. The aim of this study was to evaluate YMDD mutations in Ira...

Corresponding author: Dr. Oguz Karabay, Department of Clinical Microbiology and Infectious Diseases, Izzet Baysal University School of Medicine, Golkoy, Bolu, Turkey. E-mail: [email protected] Hepatitis B infection is prevalent worldwide and a major health burden due to the associated complications of hepatic fibrosis, cirrhosis and hepatocellular carcinoma that occur in the context of chroni...

BACKGROUND After treatment cessation, a high prevalence of relapse was reported in chronic hepatitis B (CHB) patients in China, especially in nucleot(s)ide analogues (NUCs)-experienced patients. Re-treatment for these patients remains unsolved. OBJECTIVES This study aims to evaluate the efficacy of PEGylated interferon in HBeAg positive patients with exposure to antiviral therapy. PATIENTS ...

BACKGROUND There is some controversy concerning the efficacy of low dose alpha interferon therapy in chronic hepatitis C. AIMS To evaluate the effectiveness of treatment with low doses of alpha interferon in chronic hepatitis C. PATIENTS One hundred and forty one patients with anti-HCV positive chronic active hepatitis C from six hospitals were enrolled in the study. METHODS Patients were...
