Genotype distribution of hepatitis C virus in West Sumatera, Indonesia.
Pak J Med Res Jan ;55(4):113-5.

Background: The genomes of HCV variants display considerable sequence divergence and have been classified into six genotypes and over 100 subtypes. Relatively well conserved regions of the genome such as NS5B have been used as the basis for HCV classification. HCV genotypes display different geographic distribution worldwide, a marker of response to antiviral therapy and serves as a guideline for the duration of therapy. Study design, settings and duration: Serum samples were retrieved from clinical labs of West Sumatera between June to December 2013. Materials and Methods: Sample from 50 anti-HCV positive blood donors and clinical laboratory patients were analyzed. HCV RNA and genotyping were carried out using PCR for NS5B region. Results: HCV RNA was detected in 36 samples (72.0%). Genotype analysis demonstrated three different genotypes of HCV found in West Sumatera. There were genotype 1, 2 and 3. The most frequent subtypes were 1a (54.3%) followed by subtype 1c (17.4%), 1b (11.4%), 3k (11.4%) respectively. Conclusion: HCV subtype 1a was the most prevalent in the samples from West Sumatera. Key words: HCV, PCR, genotype.
