Sustained virological response at week 12 after interferon-free therapy as criterion for HCV cure definition: Validation in a real-life cohort of HIV-coinfected patients

Sustained virological response (SVR) 12 weeks after the end-of-therapy (EOT) has been correlated with SVR24 for HCV-monoinfection. We aim to validate SVR12 as criterion for definition of HCV cure in HIV-coinfected patients treated with all-oral direct-acting antivirals (DAA). Prospectively observati...

Description
Summary:Sustained virological response (SVR) 12 weeks after the end-of-therapy (EOT) has been correlated with SVR24 for HCV-monoinfection. We aim to validate SVR12 as criterion for definition of HCV cure in HIV-coinfected patients treated with all-oral direct-acting antivirals (DAA). Prospectively observational study including HIV/HCV-coinfected subjects who received DAA and had HCV-RNA measures at weeks 12 and 24 after EOT. Every patient who took ≥1 drug dose was analyzed. DAA were prescribed to 423 patients, of whom 387 had HCV-RNA measures both at weeks 12 and 24 after EOT. SVR12 was confirmed in 379/387 patients, while SVR24 was confirmed in 377/387 subjects. The positive-predictive-value (PPV) of SVR12 for SVR24 was 99.5% (95%CI: 98.1–99.9). One of the recurrences was clinically suspected to be a late relapse. SVR12 has a high PPV for HCV cure in HIV/HCV-coinfection, though further follow-up could be necessary for those with deeper immunosuppression. En monoinfección por VHC, se ha demostrado correlación entre la respuesta viral sostenida (RVS) 12 semanas posterapia antiviral con la RVS24. Proponemos validar la RVS12 como criterio de curación en sujetos coinfectados por VIH/VHC tratados con antivirales de acción directa (AAD). Estudio observacional prospectivo con pacientes coinfectados VIH/VHC, tratados con AAD y con determinación de ARN-VHC en semanas 12 y 24 posterapia. Se analizó todo sujeto que tomó ≥1 dosis de AAD. Se prescribieron AAD a 423 sujetos: 387 tenían determinación de ARN-VHC en semanas 12 y 24 posterapia. Se confirmó RVS12 en 379/387 pacientes y RVS24 en 377/387. El valor predictivo positivo (VPP) de RVS12 para RVS24 fue del 99,5% (IC 95%: 98,1-99,9). Una recurrencia se interpretó clínicamente como recidiva tardía. La RVS12 tiene un elevado VPP para predecir curación de la infección por VHC en pacientes VIH-positivo, aunque podrían ser necesarios más controles en aquéllos más inmunosuprimidos.
