SR-BI and Antiviral Treatment Response in HCV

July 12, 2017 updated by: Ching-Sheng Hsu, Taipei Tzu Chi Hospital, Buddhist Tzu Chi Medical Foundation

Influence of Scavenger Receptor Class B Type I (SR-BI) Gene Polymorphisms on Antiviral Treatment Response, and Metabolism in Chronic Hepatitis C Patients

The scavenger receptor type B class I (SR-BI) is a receptor for high-density lipoproteins (HDL) and one of entry factors for hepatitis C virus (HCV). The investigators aimed to examine the association of single nucleotide polymorphisms (SNPs) of the SCARB1 gene, which encodes SR-BI, with virologic responses to pegylated interferon-based treatment in Asian chronic hepatitis C (CHC) patients.

Detailed Description

  1. Purpose of study: To examine the impacts of single nucleotide polymorphisms (SNPs) relevant to SR-BI on CHC patients.
  2. Study Design To enroll 400 CHC patients during a 3-year period
  3. Specify objectives of study when collecting extra specimen from participants Collect blood samples for genomic DNA to examine the SR-BI gene polymorphisms.
  4. Expected Endpoints of Treatment Sustained virologic response (SVR) means undetectable serum HCV RNA levels 24 weeks after completion of antiviral therapy.

HCV group (Peginterferon alfa-2a)
A total of 156 chronic HCV genotype 1 or 2 patients who received Peginterferon alfa-2a (Peg-IFN alfa-2a) plus ribavirin therapy were consecutively enrolled from the gastroenterological clinics.
Peginterferon alfa-2a 180μg plus daily oral weight-based ribavirin (1,000 mg for body weight 75 kg or less, 1,200 mg for body weight greater than 75 kg) for 24 or 48 weeks

Control Group
There were 153 healthy controls negative for anti-HCV enrolled simultaneously from the database of Health Management Center.
