Insights

Hepatitis C virus (HCV) infection prevalence in Macedonia is low in the general population but high in at-risk groups. Specific HCV genotypes correlate with risk factors, and OASL gene variations may predict treatment response.

Area of Science:

  • Virology
  • Hepatology
  • Genetics

Background:

  • Hepatitis C virus (HCV) poses a significant global health challenge, leading to chronic liver disease and necessitating liver transplantation.
  • Current HCV eradication therapies exhibit variable success rates (50-80%), heavily influenced by the specific HCV genotype.
  • Molecular detection of HCV in the Republic of Macedonia commenced in 1990, with extensive analysis conducted at the Research Centre for Genetic Engineering and Biotechnology.

Purpose of the Study:

  • To determine the prevalence of HCV infections and characterize genotypes within the Republic of Macedonia.
  • To investigate the association between HCV genotypes and specific risk factors in infected patients.
  • To explore the relationship between polymorphisms in the Oligoadenylate synthetase (OASL) gene and sustained virological response to HCV treatment.

Main Methods:

  • Analysis of over 4000 patient samples for molecular detection and characterization of HCV.
  • Prevalence studies in the general and at-risk populations, including hemodialysis patients and intravenous drug users.
  • Genotyping of HCV and statistical analysis of six polymorphisms in the OASL gene for association with treatment outcomes.

Main Results:

  • HCV prevalence in the general Macedonian population is 0.4%, contrasting with 23-43% in at-risk groups.
  • HCV genotype 1 is predominant in hemodialysis patients, while genotype 3 is prevalent in intravenous drug users.
  • Preliminary findings indicate an association between non-ancestral alleles in four OASL gene polymorphisms and sustained virological response in HCV-infected patients.

Conclusions:

  • HCV epidemiology in the Republic of Macedonia shows distinct genotype prevalence based on risk factors.
  • OASL gene polymorphisms present a potential predictive marker for sustained virological response in HCV treatment.
  • Further research is warranted to validate these genetic associations and their clinical implications for HCV management.

Hepatitis

Hepatitis is an inflammatory condition of the liver most commonly caused by hepatotropic viruses (A–E), though non-infectious causes such as alcohol and drugs also exist.Hepatitis AHepatitis A virus (HAV) is a non-enveloped RNA virus of the Picornaviridae family. It is primarily transmitted via the fecal-oral route, typically through ingestion of contaminated food or water. After ingestion, HAV enters the bloodstream through the oropharynx or intestinal epithelium and reaches the liver. The...

Viral Hepatitis I: Introduction

Viral hepatitis is an inflammatory condition of the liver caused by infection with hepatotropic viruses, most commonly hepatitis A, B, C, D, and E. Despite variations in structure and transmission, all viruses mentioned infect hepatocytes and provoke immune responses that can hinder liver function. Additionally, some non-hepatotropic viruses can also lead to hepatic inflammation.Hepatitis A VirusHepatitis A virus (HAV) is transmitted through the fecal–oral route, typically by ingestion of food...

Cytomegalovirus Disease

Cytomegalovirus (CMV) disease is caused by human cytomegalovirus, a double-stranded DNA virus of the Herpesviridae family. While primary CMV infection is often asymptomatic in immunocompetent individuals, the virus can cause severe disease in neonates and immunocompromised patients. CMV is the most common cause of congenital viral infection in the United States, and a major pathogen in solid organ and hematopoietic stem cell transplant recipients.CMV is transmitted via bodily fluids, sexual...
