Acute searching and early diagnosis of HCV infected persons
Insights
Hepatitis C virus (HCV) infection affects millions globally, particularly people who inject drugs (PWID). Diagnosing HCV in PWID is crucial for effective treatment with direct-acting antivirals (DAA) and disease elimination.
Area of Science:
- Hepatology
- Infectious Diseases
- Public Health
Background:
- Hepatitis C virus (HCV) infection remains a significant global health issue, impacting approximately 71 million individuals worldwide.
- People who inject drugs (PWID) represent the primary demographic for chronic HCV infection, often due to intravenous drug use.
- Direct-acting antivirals (DAA) offer highly effective treatment, achieving nearly 100% efficacy for HCV infection.
Purpose of the Study:
- To highlight the challenges in diagnosing HCV infection among people who inject drugs (PWID).
- To emphasize the need for evolving diagnostic and treatment strategies for chronic hepatitis C.
- To evaluate the effectiveness of outreach testing and collaborative approaches for HCV elimination in the PWID population.
Main Methods:
- Review of current strategies for HCV diagnosis and treatment.
- Analysis of adherence challenges in the PWID population.
- Assessment of outreach testing and partnerships with support organizations.
Main Results:
- Direct-acting antiviral (DAA) therapy demonstrates high efficacy in treating HCV.
- Poor adherence to diagnosis and treatment presents a significant barrier in the PWID population.
- Outreach testing and collaboration with support organizations are effective in improving HCV diagnosis rates among PWID.
Conclusions:
- Effective HCV elimination requires innovative approaches to diagnose and treat the infection, especially in high-risk populations like PWID.
- Integrating outreach testing and community support is vital for overcoming adherence barriers and achieving HCV eradication.
- A shift in medical professional strategies is necessary to address the changing landscape of chronic hepatitis C patients.
Abstract:
Hepatitis C virus (HCV) infection is still a major cause of chronic liver diseases, with approximately 71 million chronically infected persons worldwide. People who inject drugs currently or in the past (PWID), mostly intravenously, are the main risk group among HCV chronically infected persons. The efficacy of therapy with direct-acting antivirals (DAA) is almost 100 %. Currently, the main mission is to diagnose HCV infection in the most possible number of infected persons; it is in collision with poor adherence of PWID in particular. Changing the spectrum of chronic hepatitis C patients forces medical professionals to change their approach to diagnosis and treatment of HCV infection. Outreach testing and cooperation with support organizations showed to be an effective way to set a course to eliminate HCV in the PWID population.
