Hepatitis C--an update

Area of Science:

• Hepatology
• Infectious Diseases
• Public Health

Background:

• Chronic hepatitis C (CHC) infection is a significant global health concern with potential for severe liver complications.
• While often asymptomatic, CHC can progress to liver failure, hepatocellular carcinoma, and death, with projected increases in these outcomes.
• Successful treatment leading to viral eradication is key to reducing long-term liver-related morbidity and mortality.

Observation:

• The natural history of CHC involves a prolonged asymptomatic phase, leading to underdiagnosis.
• Current treatment rates for CHC remain low, with only a small fraction of diagnosed cases receiving therapy.
• General practitioners (GPs) are pivotal in identifying at-risk populations for screening and initiating the referral process for CHC management.

Findings:

• CHC is frequently underdiagnosed, contributing to significant patient morbidity and mortality.
• Effective treatment options are evolving rapidly, with new direct-acting antiviral therapies offering improved outcomes.
• All patients diagnosed with CHC should be evaluated for treatment, given the curable nature of the infection and the availability of new therapeutic strategies.

Implications:

• Increased awareness and screening for CHC by general practitioners can improve early diagnosis rates.
• Timely referral and treatment initiation are essential to prevent severe liver disease progression and improve patient outcomes.
• The advent of highly effective, interferon-free oral therapies signifies a paradigm shift in CHC management, making universal treatment consideration imperative.
