Insights
Hepatitis C virus (HCV) and human immunodeficiency virus (HIV) coinfection leads to worse liver disease and higher mortality. A significant racial disparity in survival was observed among coinfected patients, warranting further investigation.
Area of Science:
- Hepatology and Infectious Diseases
- Clinical Virology
- Epidemiology
Background:
- Hepatitis C virus (HCV) infection poses significant health challenges.
- Coinfection with human immunodeficiency virus (HIV) can alter disease progression.
- Understanding the impact of coinfections and demographic factors is crucial for patient management.
Purpose of the Study:
- To investigate the clinical and virological outcomes of HCV infection in patients coinfected with HIV.
- To assess the influence of race on the outcomes of HCV/HIV coinfection.
- To compare outcomes between coinfected patients and those with monoinfections.
Main Methods:
- Retrospective analysis of 265 HCV/HIV coinfected, 251 HCV monoinfected, and 227 HIV monoinfected patients.
- Data collected from 2000-2002 at the Philadelphia VA Medical Center.
- Evaluation of clinical and virological parameters, including liver function, mortality, CD4 counts, and viral titers.
Main Results:
- HCV/HIV coinfection was linked to increased liver function abnormalities (37% vs 21%/20%) and higher mortality (17% vs 6%/9%) compared to monoinfections.
- Coinfection did not significantly worsen HIV parameters (CD4, HIV titer) or increase HCV titers.
- Mortality was significantly higher in white (31%) versus black (15%) HCV/HIV coinfected patients, a disparity not seen in monoinfected groups.
Conclusions:
- HCV/HIV coinfection is associated with more severe liver disease and increased mortality.
- Coinfection does not appear to directly impact CD4 counts or viral titers.
- A notable racial disparity in mortality exists among HCV/HIV coinfected individuals, requiring further study.
Objectives:
This study was performed to examine the impact of viral coinfections and race on clinical and virological outcome of hepatitis C virus (HCV) infection.
Methods:
Three groups of patients (265 HCV/HIV coinfected, 251 HCV monoinfected, 227 HIV monoinfected) were identified between 2000 and 2002 from the computerized patient record system at the Philadelphia VA Medical Center and analyzed for clinical and virological parameters.
Results:
HCV/HIV coinfection was associated with higher frequency of liver function abnormalities (37% vs 21% vs 20%; p < 0.0003) and greater mortality (17% vs 6% vs 9% over 3 yr period, p = 0.0003, p = 0.027) compared to HCV or HIV monoinfection, respectively. However, HCV/HIV coinfection was not associated with worsened HIV-related parameters (CD4 count, HIV titer, and use of antiretroviral therapy) or increased HCV titers compared to HIV or HCV monoinfection in our population, respectively. Interestingly, mortality among HCV/HIV coinfected patients was significantly greater in white than in black patients (31% vs 15%, p = 0.011). This racial disparity in mortality was not apparent in the monoinfected groups and not explained by HBV coinfection or history of alcohol use disorder.
Conclusions:
We conclude that HCV/HIV coinfection is associated with worsened liver disease and higher mortality than HCV- or HIV-monoinfection without directly influencing CD4 count and HCV or HIV titers. Furthermore, we demonstrated a racial disparity in survival of HCV/HIV-coinfected patients that needs further investigation.
