Background: Chronic hepatitis E virus (HEV) infection may progress to end-stage liver disease in immunosuppressed individuals. Ribavirin therapy is efficient most chronic HEV patients, but 10% remain without a sustained virological response (SVR). Objectives: We aimed study whether zinc supplementation could represent therapeutic approach these patients. Methods: Antiviral properties of salts w...

The objective of this study was to evaluate the cellular proliferative potential of oral lichen planus (OLP) lesions from patients without hepatitis C virus (HCV) by means of AgNOR method, as well as the cellular proliferative potential of the normal oral mucosa from patients with HCV, treated or untreated by interferon and ribavirin. A cross-sectional study was developed to investigate four gr...

Ribavirin [1-(beta-d-ribofuranosyl)-1H-1,2,4-triazole-3-carboxamide] is the treatment of choice for hepatitis C virus infection. Ribavirin is a substrate of several nucleoside transporters, including the equilibrative nucleoside transporter (Ent) and the concentrative nucleoside transporter 2. To determine the role of Ent1 in ribavirin absorption and erythrocyte distribution, we examined its ph...

This open-label study assessed the pharmacokinetics of a single 400-mg oral dose of ribavirin in 6 healthy volunteers and 18 subjects with varying degrees of renal impairment (mild:creatinine clearance [CLcr] 61-90 mL/min/1.73 m², moderate: CLcr 31-60 mL/min/1.73 m(2), severe: CLcr 10-30 mL/min/1.73 m², n = 6 in each group). Blood and urine samples were collected pre-dose and up to 168 hours po...

Lassa fever is an acute viral hemorrhagic illness; the virus is endemic in West Africa and also of concern with regard to bioterrorism. Transmission of Lassa virus between humans may occur through direct contact with infected blood or bodily secretions. Oral administration of the antiviral drug ribavirin is often considered for postexposure prophylaxis, but no systematically collected data or u...

BACKGROUND Crimean-Congo Hemorrhagic fever (CCHF) is endemic in certain areas of Pakistan with 14 outbreaks in addition to many sporadic cases so far. It is highly fatal zoonotic disease caused by bite of infected tick. The objective of our study is to describe clinical features, treatment and outcome of CCHF positive cases during its outbreak in Hazara division, with the intention to bring foc...

This study aimed to evaluate the clinical efficacy and safety of using the traditional Chinese herbal medicine Scutellaria baicalensis for the treatment of severe HFMD in 725 patients aged >1 year in a multicenter, retrospective analysis. The patients were divided into the S. baicalensis and ribavirin groups, and the temperatures, presence or absence of skin rashes and oral lesions, nervous sys...

BACKGROUND Respiratory syncytial virus (RSV) viral load and disease severity associate, and the timing of viral load and disease run in parallel. An antiviral must be broadly effective against the natural spectrum of RSV genotypes and must attain concentrations capable of inhibiting viral replication within the human respiratory tract. OBJECTIVES We evaluated a novel RSV fusion inhibitor, MDT...
