In this project, the investigators aim to study the role of biliverdin reductase A (BLVRA) in HCV infected patients prior and during/after standard antiviral therapy in association with viral clearance, disease progression and treatment response and in comparison with healthy subjects.

Further study details as provided by Charles University, Czech Republic:

Primary Outcome Measures:
  • To assess differences in BLVRA expression in the liver and PBMC in HCV infected patients in responders and non-responders to standard antiviral therapy. [ Time Frame: 72 weeks ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • To analyze the association of genetic polymorphisms of BLVRA with disease progression and treatment response in HCV infected patients. [ Time Frame: 3 years ] [ Designated as safety issue: No ]

Biospecimen Retention:   Samples With DNA
peripheral blood, liver biopsy

Enrollment: 113

Primary Completion Date: March 2013 (Final data collection date for primary outcome measure)
chronic HCV infection
The study was performed on therapeutically naïve patients with chronic HCV infection. Patients with positivity of anti-HCV antibodies, and detectable HCV RNA in serum for at least 6 months, were included in the study.

Detailed Description:
  1. To analyze biliverdin reductase (BLVRA) expression in the liver of HVC infected patients undergoing liver biopsy followed by standard antiviral treatment (peg-interferon plus ribavirin combination therapy) and patients with other forms of liver diseases undergoing liver biopsy as controls.
  2. To analyze BLVRA expression in peripheral blood leukocytes (PBL) of therapeutically naïve HCV patients, during/after standard antiviral therapy and healthy controls.
  3. To analyze BVLRA genetic polymorphisms both in HCV infected patients and healthy controls.

Ages Eligible for Study:   18 Years to 60 Years
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   Yes
Sampling Method:   Non-Probability Sample
Study Population
Estimated enrollment: BLVRA expression study: 50 - 100 HCV patients 50 healthy volunteers Polymorphisms of BLVRA study: 300 HCV patients

Inclusion Criteria:
