Insights
Hepatitis C virus (HCV) subtype 1b is prevalent in elderly patients in Eastern Sicily. This finding suggests subtype 1b is indigenous but not the sole prognostic factor for chronic hepatitis C (CHC) severity or interferon response in this age group.
Area of Science:
- Hepatology
- Virology
- Epidemiology
Background:
- Hepatitis C virus (HCV) genotype and subtype determination is crucial for understanding epidemiological characteristics.
- HCV subtypes serve as prognostic factors for disease severity and interferon (IFN) treatment response in chronic hepatitis C (CHC).
- Limited data exists on HCV genotype prevalence and its clinical implications in elderly CHC patients.
Purpose of the Study:
- To determine HCV genotypes and subtypes in elderly CHC patients (65-75 years) in Eastern Sicily.
- To gather epidemiological data on HCV genotype prevalence in this specific demographic.
- To evaluate the relationship between HCV subtypes, disease severity, and IFN response in elderly patients.
Main Methods:
- Study involved 22 elderly CHC patients (Group A, 65-75 years).
- HCV-RNA subtypes were analyzed and compared with younger cohorts (Group B: 36-64 years; Group C: 20-35 years).
- Prevalence of HCV subtypes was assessed across the age groups.
Main Results:
- HCV-RNA was detected in 20 out of 22 elderly patients (90.9%).
- HCV subtype 1b was the predominant subtype (100%) in the elderly group.
- Other HCV subtypes were more frequent in younger patient groups, particularly in the youngest cohort.
Conclusions:
- HCV subtype 1b appears to be indigenous to Eastern Sicily.
- HCV subtype 1b alone cannot be considered the sole prognostic factor for disease severity or IFN response in elderly CHC patients.
- Further research is needed to understand the complex interplay of HCV genotypes, age, and treatment outcomes.
Abstract:
The importance of determination of hepatitis C virus (HCV) genotypes and subtypes has been demonstrated not only as epidemiological characteristics, but also as prognostic factors regarding the seriousness of the disease and response to interferon (IFN) in patients with chronic hepatitis C (CHC). Aim of this study was to determine HCV genotypes in a group of elderly patients with CHC, in order to acquire epidemiological data on the prevalence of HCV genotypes in Eastern Sicily, and to evaluate any relationship with the seriousness of the disease and with the response to IFN. The study was carried out on 22 patients with CHC, aged from 65 to 75 years. The prevalence of HCV-RNA subtypes in elderly patients (Group A) was compared with two other groups: Group B aged from 36 to 64 years; and Group C aged from 20 to 35 years. HCV-RNA proved to be positive in 20 of the 22 patients in Group A, and in 100% of these cases the prevalent subtype was 1b; in the other two groups the occurrence of other subtypes was more frequent, especially in the younger ages. In conclusion, the subtype 1b is indigenous in our region and it cannot be proposed as the only prognostic factor for seriousness of the disease and response to IFN, especially in elderly patients.
