چکیده

Background HCV infection induces hepatic and extra-hepatic damage that includes kidney and neurocognitive dysfunction. Tryptophan (Trp) is catabolized into immunosuppressive kynurenine (Kyn) by indoleamine 2,3-dioxygenase (IDO) and tryptophan 2,3 dioxegenase (TDO). Increased Trp catabolism measured by Kyn/Trp ratio has been associated with neurocognitive impairment and immune dysfunction in HIV mono-infection. Here, we assessed the contribution of Trp catabolism in HCV/HIV co-infected patients.

Influence of Hepatitis C Virus Sustained Virological Response on Immunosuppressive Tryptophan Catabolism in ART-Treated HIV/HCV Coinfected Patients

BACKGROUND We previously reported an association between tryptophan (Trp) catabolism and immune dysfunction in HIV monoinfection. Coinfection with HIV is associated with more rapid evolution of hepatitis C virus (HCV)-associated liver disease despite antiretroviral therapy (ART), possibly due to immune dysregulation. We hypothesized that liver fibrosis in HIV/HCV coinfection would be associated...

Hepatic fibrosis and immune phenotype vary by HCV viremia in HCV/HIV co-infected subjects

HCV and HIV independently lead to immune dysregulation. The mechanisms leading to advanced liver disease progression in HCV/HIV coinfected subjects remain unclear.In this cross-sectional study, we assessed the association of HCV viremia, liver fibrosis, and immune response patterns in well-characterized HIV phenotypes: Elite controllers (Elites), HIV controlled (ARTc), and HIV uncontrolled (ART...

Predictive Value of Liver Enzymes and Inflammatory Biomarkers for the Severity of Liver Fibrosis Stage in HIV/HCV Co-Infected Patients

OBJECTIVE The aim of our study was to assess a possible association between plasma inflammatory biomarkers (CRP, IL-6, soluble CD14) and the extent of fibrosis or cirrhosis using a FibroScan® in HIV/HCV co-infected patients. METHODS This cross-sectional study assessed 60 HIV/HCV co-infected patients who had paired plasma samples and FibroScan® values available. All included patients were cont...

HCV virological response during treatment of chronic hepatitis C is associated with liver histological improvement in patients with HCV/HIV co-infection.

Liver histological improvement after treatment for chronic hepatitis C in patients co-infected with human immunodeficiency virus-1 (HIV-1) has been described. Paired liver biopsies in twenty six HCV/HIV co-infected patients were compared to determine factors possibly associated with histological improvement. The patients were submitted to a liver biopsy before treatment for hepatitis C and 25 m...

Progression of liver fibrosis in HIV/HCV genotype 1 co-infected patients is related to the T allele of the rsI2979860 polymorphism of the IL28B gene

OBJECTIVE HIV/HCV co-infection is characterised by accelerated progression of liver disease. Recently, the rs12979860 C/T polymorphism in the IL28B gene has been linked to progression towards cirrhosis in HCV mono-infected patients and to treatment response of HCV-infection in HIV/HCV co-infected patients. Our aim was to clarify by non-invasive techniques if this polymorphism affects fibrosis p...
