The clinical challenge of managing patients after sustained virological response with direct-acting antivirals for Hepatitis C.

PURPOSE OF REVIEW: This review highlights the critical considerations for monitoring patients who achieve sustained virological response (SVR) after direct-acting antiviral (DAA) therapy for hepatitis C virus (HCV) infection. Despite the remarkable success of DAAs, challenges persist in managing long-term risks, including hepatocellular carcinoma (HCC), liver decompensation, and extrahepatic manifestations, necessitating a tailored follow-up approach.

RECENT FINDINGS: Recent studies emphasize that SVR does not eliminate risks for complications, particularly in patients with advanced fibrosis or cirrhosis. Advances in noninvasive tools, such as transient elastography and blood-based markers, have improved assessment of portal hypertension and liver function dynamics post-SVR. HCC surveillance remains critical for high-risk groups. Additionally, SVR improves extrahepatic conditions like mixed cryoglobulinemia and non-Hodgkin lymphoma, though careful monitoring for recurrence or associated risks is advised. Reinfection in high-risk populations underscores the importance of structured prevention and retreatment strategies.

SUMMARY: Tailored follow-up of post-SVR patients remains essential. Future research should focus on refining predictive tools for late complications and optimizing surveillance strategies, balancing cost-effectiveness with clinical outcomes.
