Insights
Hepatitis C virus (HCV) genotype 1 is dominant in Romania, affecting 99% of patients. This study highlights an epidemic profile of HCV infection in Romania and neighboring countries, with increased prevalence and fibrosis in older individuals.
Area of Science:
- Hepatology
- Virology
- Epidemiology
Background:
- Hepatitis C virus (HCV) infection remains a significant global health concern.
- Understanding HCV genotype distribution is crucial for effective treatment strategies and epidemiological surveillance.
- Romania's HCV genotype landscape has not been extensively studied on a national level.
Purpose of the Study:
- To determine the predominant HCV genotype in Romania through the first national study.
- To correlate HCV genotype distribution with epidemiological, biochemical, virological, and histological factors.
- To compare Romania's HCV genotype data with that of neighboring countries.
Main Methods:
- Two patient cohorts were analyzed using different genotyping assays (Versant HCV genotype 2.0 and Roche Molecular System).
- A total of 153 patients were genotyped in the ACHIEVE study, and 461 in the Epidemiological National Multicenter Study (ENMS).
- Epidemiological, biochemical, virological, and histological data were collected from the ENMS group.
Main Results:
- HCV genotype 1b was identified in 93.46% of patients in the ACHIEVE study, and genotype 1 in 99.13% in the ENMS study.
- Percutaneous transmission routes accounted for 85.9% of cases, with higher prevalence in older age groups.
- Significant fibrosis (>= F2) was observed in 70.9% of patients over 40, with no correlation between viral load/ALT levels and histological outcomes.
Conclusions:
- HCV genotype 1 is nearly exclusive among Romanian patients with chronic hepatitis C.
- The consistent genotype distribution in Romania, Moldova, and Hungary suggests a shared epidemic profile.
- These findings underscore the need for targeted public health interventions for HCV in the region.
Aim:
To investigate the HCV genotype distribution in Romania in the first national study, to establish the correlations with epidemiological, biochemical, virological and histological features and to compare our results with those from neighboring countries.
Patients And Methods:
Two distinct groups of patients and two methods were used: 153 patients in the frame of ACHIEVE study with genotyping and subtypes determination (Versant HCV genotype 2.0 assay) and 461 patients in the frame of an Epidemiological National Multicenter Study having only genotype determination with a commercial kit (Roche Molecular System). Epidemiological, biochemical, virological and histological features were investigated only in the ENMS group.
Results:
Genotype 1b was found in 93.46% (ACHIEVE study) and genotype 1 (without subtype identification) in 99.13% of patients (ENMS study). Percutaneous routes of transmission were found in 85.9% of cases. The prevalence of HCV infection increased with age. A high viral load (> or = 600,000 IU/ml) was found in 67.9% of patients, especially those older than 40 years. Significant fibrosis > or = F2 was present in patients older than 40 years (70.9%). There were no correlations between HCV-RNA levels and histological features or between ALT levels and METAVIR activity or fibrosis scores. A similar homogeneity of HCV genotype distribution has been reported for Moldavia (96%) and Hungary (94.5%).
Conclusions:
Type 1 HCV genotype was found almost exclusively in Romanian patients with chronic hepatitis C by two different methods of investigation. The pattern showed by this distribution in Romania and some neighboring countries suggests an epidemic profile of HCV infection.
