Distribution of hepatitis C virus genotypes in Slovenia
1Institute of Microbiology and Immunology, Medical Faculty, Ljubljana, Slovenia.
Insights
Hepatitis C virus (HCV) genotype distribution varies significantly among different transmission groups in Slovenia. Understanding these HCV patterns is crucial for targeted prevention and treatment strategies.
Area of Science:
- Hepatology
- Virology
- Epidemiology
Background:
- Hepatitis C virus (HCV) infection remains a significant global health concern.
- Genotype distribution of HCV varies geographically and by transmission route.
- Understanding local HCV epidemiology is essential for effective public health interventions.
Purpose of the Study:
- To determine the prevalence of different hepatitis C virus (HCV) genotypes in Slovenia.
- To analyze HCV genotype distribution across various epidemiological groups.
- To investigate the relationship between HCV genotypes and transmission routes.
Main Methods:
- A cohort of 203 subjects infected with HCV in Slovenia was studied.
- The Inno-Lipa HCV II assay was used for HCV genotyping.
- Data were analyzed based on patient groups: blood transfusion recipients, chronic hepatitis C patients of unknown cause, intravenous drug users, and haemodialysis patients.
Main Results:
- HCV subtype 1b was prevalent in blood transfusion recipients (81%) and chronic hepatitis C patients (54.4%).
- Intravenous drug users predominantly had HCV genotype 3 (45.9%) and subtype 1a (43.2%).
- Haemodialysis patients showed nearly equal frequencies of HCV genotypes 1 (40.5%) and 2 (37.8%).
Conclusions:
- Significant differences in HCV genotype distribution were observed among distinct epidemiological groups in Slovenia.
- The findings suggest a strong association between specific HCV genotypes and particular routes of viral transmission.
- These results highlight the importance of tailored approaches for HCV management based on genotype and transmission patterns.
Abstract:
To determine the prevalence of HCV genotypes in Slovenia, 203 subjects infected with hepatitis C virus (HCV) were studied using the Inno-Lipa HCV II assay (Innogenetics, Belgium). Of 21 patients infected by blood transfusion 19% had HCV subtype 1a, 81% had subtype 1b, and none of them was infected with genotype 3. In chronic hepatitis C patients infected by unknown cause subtype 1b was the most prevalent (54.4%), followed by subtype 1a (24.6%), genotype 3 (15.8%) and genotype 2 (5.2%). Genotype 3 (45.9%) and subtype 1a (43.2%) predominated among 74 intravenous drug users. In 37 haemodialysis patients genotypes 1 and 2 were almost equally frequent (40.5% and 37.8%, respectively), followed by genotype 3 (21.6%). Significant differences in HCV genotype distribution among distinct epidemiological groups observed in Slovenia indicate a close relationship between certain HCV genotypes and particular routes of viral transmission.
