Insights
Hepatitis C virus (HCV) genotype 3, particularly subtype 3a, is most common in Greek patients. Genotype distribution shows ongoing changes, with subtype 3a prevalent in younger males.
Area of Science:
- Hepatology
- Virology
- Public Health
Background:
- Hepatitis C virus (HCV) infection poses a significant global health challenge, leading to severe liver conditions like cirrhosis and cancer.
- HCV exhibits considerable genetic diversity, with distinct genotypes and subtypes varying regionally.
- Understanding the prevalence of HCV genotypes is crucial for effective treatment strategies and public health interventions.
Purpose of the Study:
- To determine the frequency distribution of Hepatitis C virus genotypes in Greek patients with chronic infection.
- To identify the most common HCV subtypes circulating in Greece.
- To analyze demographic associations with specific HCV genotypes.
Main Methods:
- Analysis of viral load and HCV genotyping was performed on specimens from 82 patients with chronic HCV infection.
- Patients represented diverse risk groups, encompassing both males and females.
- Data collection focused on identifying the prevalence of different HCV genotypes and subtypes.
Main Results:
- HCV genotype 3 was the most prevalent (41.5%), followed by genotype 1 (34.1%) and genotype 2 (12.2%).
- The most common subtypes identified were 3a (32.9%) and 1b (26.8%).
- Mixed infections within genotypes were observed in 14 subjects, but no mixed infections across different genotypes occurred.
Conclusions:
- Hepatitis C virus genotypes 3a and 1b are the predominant types in the Greek patient population studied.
- HCV genotype 3a demonstrated a higher prevalence among younger and male patients.
- The findings suggest a dynamic and evolving distribution pattern of HCV genotypes in Greece.
Background:
Hepatitis C is a major public health problem. HCV infection contributes to progressive liver disease, cirrhosis, and hepatocellular carcinoma. HCV has high genetic heterogeneity and is classified into various genotypes and subtypes. Regional differences exist in their distribution. The aim of this study was to investigate the relative frequency of HCV genotypes in Greek patients with chronic infection.
Methods:
We evaluated 82 patients with chronic HCV infection, both males and females, belonging to different risk groups. We performed viral load measurement and HCV genotyping in all specimens.
Results:
HCV genotype 3 was the most prevalent (41.5%) followed by genotype 1 (34.1%), 2 (12.2%), 4 (10.9%), and 5 (1.2%). Genotype 6 was not detected in any patient. Most prevalent subtypes were 3a (32.9%), 1b (26.8%), and 2a (6.1%). Fourteen subjects revealed mixed infections within types. There were no cases with mixed infections across types.
Conclusions:
Our data indicate that genotypes 3a and 1b are the most prevalent in Greek patients. Genotype 3a is predominant in younger patients and also in male patients. Moreover, HCV genotype distribution is in continuous temporal change in Greece.
