Description
Summary:ABSTRACT: Introduction and Objectives: Hepatitis C-induced liver disease represents a significant threat to the survival of people living with HIV. HIV/HCV-coinfected individuals have a more rapid progression to cirrhosis and its complications than HCV monoinfected patients. Although the underlying mechanisms remain unclear, HLA-G, a non-classical class I HLA molecule, has a well-recognized property to down-regulate the immune response against viruses and may favor the progression of chronic hepatitis C. Materials and Methods: We analyzed HLA-G expression in 59 liver specimens of patients harboring chronic HCV and HIV coinfection and stratified the findings according to clinical and histopathological features. Results: Genotype 1 was the most prevalent (88%); the HLA-G expression was observed in 38 (64%) liver specimens, and it was more frequent in more severe stages than in milder stages of chronic hepatitis (94,1% x 55%; p<0.01). HLA-G expression in the liver was not correlated to antiviral response to hepatitis C therapy with pegylated-IFN-α plus ribavirin. Conclusions: HLA-G expression in the context of HCV/HIV coinfection is a complex process modulated by many factors. HLA-G expression may play a role in the mechanisms that facilitate disease progression and may contribute to the deterioration of the immune response against HCV in individuals living with HIV.
