HIV-DNA Dynamics in HIV Monoinfected or HIV/HCV Coinfected Patients (ViDyMoCo)
Dynamics of Viral Reservoir in HIV-positive Patients With or Without HCV Coinfection in the Era of Direct-acting Antiviral and Antiretroviral Drugs
Studienübersicht
Detaillierte Beschreibung
New markers of viral activity are now under investigation. Besides HIV-RNA and CD4 cells count, HIV-DNA is an emerging marker of viral reservoir, that seems to be associated with the risk of HIV-related diseases, especially in HCV coinfected patients. New antiretroviral drugs, particularly integrase inhibitors, are expected to decrease residual viremia and, consequently, viral reservoir. Monitoring of HIV-DNA dynamics during antiretroviral treatment could lead to a better management of HIV infected population.
Also, the role of HCV in influencing HIV natural history requires careful monitoring. In particular, with a broader use of direct acting antiretroviral, the analysis of prevalence of HCV resistance associated mutation will be more and more important to manage patients with treatment failure.
