Culture-based preemptive therapy with ganciclovir was shown to reduce the incidence of cytomegalovirus (CMV) disease after bone marrow transplantation (BMT). Culture techniques did not detect CMV in 12% to 13% of patients before the onset of CMV disease. In a prospective study, 71 patients either received preemptive therapy based on polymerase chain reaction (PCR) technique (37 patients) or on ...

Herpes simplex encephalitis is a rapidly progressive disease in neonates and adults. Mortality is high, and there are severe neurologic sequelae in survivors. The reasons for centripetal transfer of virus to the brain are not fully understood. Prompt diagnosis followed by antiviral therapy with acyclovir significantly improves the prognosis. Controversy surrounds the need for brain biopsy befor...

BACKGROUND AND AIMS The aims of this study were to explore the correlation between chronic hepatitis B virus (HBV) drug-resistant mutation profiles and the efficacy of nucleoside analog rescue therapy in patients with initial antiviral treatment failure. PATIENTS AND METHODS Patients with initial antiviral therapy failure were recruited between January 2011 and January 2013 from the Division ...

Objective. The introduction of protease inhibitors telaprevir and boceprevir in 2011 had extended the antiviral treatment options especially in genotype 1 infected hepatitis C relapsers and nonresponders to interferon/ribavirin therapy. The aim of this study was to analyze the long-term treatment efficiency of telaprevir-based triple therapy for patients with hepatitis C reinfection after ortho...

OBJECTIVES The effect of antiviral therapy on clinical outcomes in chronic hepatitis B virus (HBV) is not established. We aimed to assess the effects of interferon and/or nucleos(t)ide analogues versus placebo or no intervention on prevention of hepatocellular carcinoma (HCC) and mortality in chronic HBV. DESIGN Random-effects pairwise meta-analysis of randomised trials and observational stud...

OBJECTIVES To determine whether antiviral therapy reduces the risk of developing hepatocellular carcinoma (HCC) in chronic hepatitis C. DESIGN Systematic review and meta-analyses of randomised controlled trials. Prospective cohort studies were included in sensitivity analyses. DATA SOURCES Eligible trials were identified through electronic and manual searches. STUDY SELECTION Eight random...

background to treat viral infection of chronic hepatitis c (chc) is a main strategy to prevent progression of liver disease, and cancer. some patients with chc have failed to respond to the common antiviral therapy in different populations. objectives in the current study it was aimed to find out the possible role of multiple drug resistance gene1 (mdr1) in non-responder patients with chc infec...

Background and aim Studies suggest that antiviral therapy performed after curative resection improves the postoperative prognosis of hepatitis B virus (HBV)-related hepatocellular carcinoma (HCC), but the evidence has been contradictory. The aim of this meta-analysis was to assess the effect of antiviral therapy with nucleoside analogs (NAs) after curative resection on the long-term postoperati...

Hepatitis C virus (HCV) infection is a major worldwide problem causes acute and chronic HCV infection. Current treatment of HCV includes pegylated interferon-α (PEG IFN- α) plus ribavirin (RBV) which has significant side effects depending upon the type of genotype. Currently, there is a need to develop antiviral agents, both from synthetic chemistry and Herbal sources. In the last decade, vario...

The management of chronic hepatitis B currently rests with long-term therapy using oral nucleoside analogs. The major limitation of long-term therapy is antiviral resistance. Antiviral resistance is due to the high rate of mutations that can occur during hepatitis B virus (HBV) replication and the selection of these mutants due to a replication advantage in the presence of the antiviral agent. ...
