[Characterization of hepatitis C virus in chronic hepatitis patients: genotypes in the State of Amazonas, Brazil].

Introduction: In the State of Amazonas, data regarding the prevalence of different genotypes of hepatitis C virus remains scarce.

Methods: The genotype of 69 HCV positive patients was determined. An in-house standardized nested-PCR was used to detect HCV RNA.

[Sustained virological response in patients with coinfection by hepatitis C virus genotypes 1 and 2, after just nine weeks of antiviral therapy: case report].

A report of a 67 year-old male patient with positive serology for HCV. PCR revealed the presence of HCV RNA, viral load of 2,000 copies/mL and genotypes 1 and 2. The patient was treated with peginterferon alfa-2a at 180 mcg/week and ribavirin at 1,000 mg/day.

Hepatitis C virus screening and clinical monitoring of biomarkers in patients undergoing hemodialysis.

In this study, 395 volunteers were enrolled to investigate the seroprevalence of hepatitis C virus, the immunological and the alanine aminotransferase (ALT) biomarkers amongst hemodialysis patients, living in Manaus, Brazil. An overall seroprevalence of 13.9% was found in the hemodialysis patients.
