Insights

Hepatitis C virus (HCV) and human immunodeficiency virus (HIV) co-infection affects millions globally. Direct-acting antivirals (DAAs) are effective in treating HCV in people living with HIV (PLWH), reducing liver disease progression and hepatocellular carcinoma risk.

Area of Science:

  • Hepatology and Virology
  • Infectious Diseases
  • Public Health

Background:

  • Hepatitis C virus (HCV) and human immunodeficiency virus (HIV) co-infection impacts 2.3 million individuals worldwide, with people living with HIV (PLWH) being six times more affected.
  • Higher HCV prevalence is observed in specific populations, including people who inject drugs and men who have sex with men, where HIV infection can increase sexual transmission risk.
  • Untreated chronic hepatitis in co-infected patients can lead to end-stage liver disease and hepatocellular carcinoma (HCC), with HIV also increasing vertical transmission risk.

Discussion:

  • Direct-acting antivirals (DAAs) represent the current standard for HCV treatment, crucial for mitigating liver disease progression and HCC risk in both mono- and co-infected individuals.
  • Early-stage fibrosis treatment with DAAs significantly reduces liver disease mortality and morbidity.
  • Sustained virological response rates in PLWH post-HCV eradication have led to revised treatment guidelines, now including individuals living with HIV in simplified HCV treatment algorithms.

Key Insights:

  • HCV eradication using DAAs can influence lipid metabolism, potentially causing dyslipidemia.
  • The efficacy of DAAs in HCV/HIV patients must also consider their impact on glucose metabolism, linked to improved liver function.
  • Advancements in HCV treatment offer significant benefits for PLWH, improving liver health outcomes and reducing cancer risk.

Outlook:

  • Continued research into the long-term metabolic effects of DAAs in co-infected populations is warranted.
  • Developing effective vaccination strategies for both HCV and HIV remains a critical unmet need.
  • Further optimization of HCV treatment algorithms for PLWH will enhance disease management and patient survival.
