HCV genotype shift occurred over the 15 years in PWIDs in the Czech Republic

Popis výsledku v původním jazyce

Objectives: To follow on the epidemiology of HCV, especially genotypes spreading among people who inject drugs (PWID) in Prague and surrounding Central Bohemia, Czech Republic. Methods: 546 patients who reported past and/or recent injecting of drugs were recruited in the years 2010-2012. They were initially tested for anti-HCV. Real-time PCR was used for quantification and genotyping of hepatitis C virus. Obtained data from the years 2010-2012 were compared with historical controls from periods of 1998-2000 and 2005-2007. Results: Of 546 initially recruited and tested patients were 393 (72%) anti-HCV seropositive and of them 269 (68.4%) had detectable HCV PCR RNA. The most prevalent subtype was 3a in 97 patients (36.1%), 1a was detected in 85 patients (31.6%) and 1b in 57 patients (21.2%). These three genotypes were responsible for nearly 89% of infections. Conclusion: Significant increase in both genotypes 1a and 3a over the 15 years was apparent and significant, followed by the decrease in genotype 1b. In the genotype 1b and genotype 3a the significance has risen with the years of data collection. Described genotypic shift reflects the evolution of HCV epidemics and corresponds with the mode of transmission.
