Abstract

Background: Hepatitis C virus (HCV)/human immunodeficiency virus (HIV) co-infection has become a serious public health problem especially in high risk groups such as injection drug users in China. However, the impact of HIV infection and antiretroviral therapy (ART) on HCV viral load which is usually regarded as a predictor of liver disease progress had not been well studied in this country.
Objectives: To explore correlations of HIV co-infection and ART with plasma HCV load among HCV-infected patients in an ethnic minority area in Yunnan Province, China.Patients and Methods: HCV/HIV co-infected patients and HCV mono-infected controls were examined and compared for plasma HCV RNA and related risk factors.
Results: A total of 145 HCV/HIV co-infected patients and 25 HCV mono-infected controls were studied. The majority of the participants were male, belonged to an ethnic minority and were younger than 45 years old. HCV viral suppression rate with undetectable plasma HCV viral load was 28.3% in the HCV/HIV co-infected patients, 36% among HCV mono-infected controls and 29.4% overall. ART-prescribed HCV/HIV co-infected patients had significantly higher HCV viral loads (IQR: (3.80-6.44)*log10 copies ml-1) than those naïve to ART (IQR: (undetectable-6.41)*log10 copies ml-1) and HCV mono-infected patients (IQR: (undetectable-5.44)*log10 copies ml-1). Men, from the Dai minority and those with more than six years education, were also shown to have a higher plasma HCV viral load,according to multiple logistic regression analysis.
Conclusions: ART potentially increases the plasma HCV viral load among HCV/HIV coinfected patients in an ethnic minority area in China. Future large scale prospective cohort studies are needed to address the controversy associated between HIV co-infection and the natural history of HCV.



Implication for health policy/practice/research/medical education:

This pilot study shows that HIV infection and ART were potentially related with increased plasma HCV viral load and diminished ability of viral clearance in a setting of multiple ethnicities in China. These findings appeals for strengthened surveillance and treatment for HCV/HIV co-infected patients as well as prospective cohort studies to further determine the interaction between both virus infections in disease progress.
