ViDyMoCo: HIV-DNA Dynamics in HIV Monoinfected or HIV/HCV Coinfected Patients
Study Details
Study Description
Brief Summary
New markers of viral activity are now under investigation. Aim of the study is to investigate the efficacy of new antiretroviral drugs by monitoring HIV-DNA dynamics in HIV-positive population. In HIV/HCV coinfected population, the study of HIV reservoir dynamics and the analysis of the prevalence of HCV resistance-associated mutations will help clinicians to improve the management of coinfected patients.

Detailed Description
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.
Study Design
Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Naive patients Patients who begin their first antiretroviral regimen. Blood sample withdrawal |
Procedure: Blood sample withdrawal
Blood withdrawal for HIV-DNA or HCV resistance test
|
| Experienced patients Patients with a history of antiretroviral treatment, switching to a new regimen. Blood sample withdrawal |
Procedure: Blood sample withdrawal
Blood withdrawal for HIV-DNA or HCV resistance test

Outcome Measures
Primary Outcome Measures
- Percentage of HIV-positive patients with a significant HIV-DNA decay after 3 years from a new antiretroviral regimen start [up to 144 weeks]
Secondary Outcome Measures
- Percentage of HIV/HCV coinfected patients with a significant HIV-DNA decay after 3 years from the enrollment [up to 144 weeks]
- Measurement of HIV-DNA level during HCV antiviral therapy with DAA in HIV/HCV coinfected patients [up to 24 weeks]
- Prevalence of HCV resistance-associated variants and their relation with HIV-DNA levels in HIV/HCV coinfected patients, treated or not treated for HCV. [up to 144 weeks]
- Comparison of the prevalence of HCV resistance-associated variants in HIV/HCV coinfected population versus HCV monoinfected population [up to 144 weeks]
