Acute HCV in HIV-positive individuals - a review

Area of Science:

• * Infectious Diseases
• * Hepatology
• * Public Health Virology

Background:

• * Hepatitis C virus (HCV)/Human Immunodeficiency Virus (HIV) co-infection affects 10-25% of HIV-positive individuals.
• * HCV is a leading cause of morbidity and mortality in the HIV population, especially after effective HIV therapies.
• * Acute HCV diagnoses have significantly increased in HIV-positive populations since the early 2000s.

Purpose of the Study:

• * To review the epidemiology, natural history, immunology, and virology of acute HCV in HIV-positive individuals.
• * To highlight the increasing significance of HCV as a public health issue within the HIV community.

Main Methods:

• * Review of molecular studies and cohort data on HCV/HIV co-infection.
• * Analysis of transmission routes and risk factors.
• * Examination of immunological responses and treatment data.

Main Results:

• * Multiple HCV variants circulate within HIV-positive men who have sex with men (MSM).
• * Evidence suggests a large international transmission network, particularly in Europe.
• * Permucosal risk factors, including high-risk sexual and drug use behaviors, are associated with transmission.
• * HIV impacts cell-mediated immune responses to HCV, increasing persistence rates.

Conclusions:

• * Acute HCV in HIV-positive individuals presents unique epidemiological, immunological, and virological characteristics.
• * Permucosal transmission highlights the need for targeted public health interventions.
• * Early treatment with pegylated interferon and ribavirin is supported by current data.
• * Addressing behavioral risk factors requires a concerted effort from public health specialists, clinicians, and patients.
