[Study on HCV genotypes in different clinical types of hepatitis C patients in Shenyang area]
1Department of Infectious Diseases, Second Affiliated Hospital of China Medical University, Shenyang, 110003.
Insights
Hepatitis C virus (HCV) genotype II is the most common in Shenyang, followed by genotype III. HCV genotypes correlate with hepatitis C severity, impacting clinical outcomes.
Area of Science:
- Hepatology
- Virology
- Molecular Biology
Context:
- Hepatitis C virus (HCV) infection remains a significant global health concern.
- Understanding HCV genotype distribution is crucial for effective treatment strategies.
- Previous studies have indicated regional variations in HCV genotype prevalence.
Purpose:
- To investigate the distribution of HCV genotypes among different clinical presentations of hepatitis C in the Shenyang region.
- To determine the clinical significance of specific HCV genotypes in relation to disease severity.
Summary:
- A study of 84 hepatitis C patients in Shenyang utilized PCR assay to identify HCV genotypes.
- Hepatitis C virus (HCV) genotype II was predominant (53.6%), followed by genotype III (30.9%) and mixed genotypes (15.5%).
- Genotype distribution varied significantly across clinical types (P < 0.05), with genotype II more prevalent in severe chronic hepatitis and liver cirrhosis.
Impact:
- The findings highlight the predominance of HCV genotype II in the Shenyang area.
- This research demonstrates a clear association between specific HCV genotypes and the clinical severity of hepatitis C.
- Understanding these genotype-clinical correlations can inform targeted therapeutic approaches and prognostic assessments.
Objective:
To study the distribution of HCV genotypes in different clinical types of hepatitis C in Shenyang area and its clinical significance.
Methods:
The HCV genotypes of 84 HC patients of different clinical types were detected by PCR assay with four kinds of type-specific primers.
Results:
In 84 patients with hepatitis C, the HCV-II and HCV-III genotypes and the II/III mixed genotype were 53.6%, 30.9% and 15.5% respectively. The distribution of HCV genotypes in different HC clinical types was not identical, P < 0.05. In acute hepatitis, in mild, moderate and severe degree of chronic hepatitis, and in liver cirrhosis, the infection rates of genotype II HCV were 55.6%, 36.2%, 75.0%, 85.7% and 88.9% respectively, but that of genotype III were 22.2%, 46.8%, 8.3%, 0% and 11.1% respectively.
Conclusion:
Infection of geno type II HCV was predominant in Shenyang area followed by HCV-III and II/III mixed genotypes. The different genotypes of HCV were related to the severity of hepatitis C.
