The aim of this study was to investigate the impact of HBcAb positivity on the progression of liver fibrosis (Fibrosis-4 score> 3.25) in the Italian cohort of HIV-infected individuals naïve to antiretroviral treatment (ICONA). All patients with FIB-4 <3.25 at baseline were evaluated prospectively: 6966 PLWH (People Living with HIV) patients were screened and classified based on HBV and HCV serology. Patients who were HBcAb+/HCV-/HBsAg- and HCV+/HBcAb+/HBsAg-, or HBsAg+/HBcAb+/HCV- had CD4 + cell counts below the nadir and significantly higher prevalence of AIDS diagnosis at baseline than the other groups (p <0.0001). Cox regression model adjusted for age, HIV transmission mode, country of birth and alcohol consumption, showed a higher relative risk (HR) of progression to FIB-4> 3.25 in HCV+/HBcAb+/HBsAg- patients (HR 7.2, 95% CI 3 8 -13.64).HBcAb+ contribute to liver damage in HIV+/HCV+/HBcAb+/HBsAg- subjects. A careful monitoring for signs of previous HBV infection is needed in this kind of patients.

Abstract

The aim of this study was to investigate the impact of HBcAb positivity on the progression of liver fibrosis (Fibrosis-4 score> 3.25) in the Italian cohort of HIV-infected individuals naïve to antiretroviral treatment (ICONA). All patients with FIB-4 <3.25 at baseline were evaluated prospectively: 6966 PLWH (People Living with HIV) patients were screened and classified based on HBV and HCV serology. Patients who were HBcAb+/HCV-/HBsAg- and HCV+/HBcAb+/HBsAg-, or HBsAg+/HBcAb+/HCV- had CD4 + cell counts below the nadir and significantly higher prevalence of AIDS diagnosis at baseline than the other groups (p <0.0001). Cox regression model adjusted for age, HIV transmission mode, country of birth and alcohol consumption, showed a higher relative risk (HR) of progression to FIB-4> 3.25 in HCV+/HBcAb+/HBsAg- patients (HR 7.2, 95% CI 3 8 -13.64).HBcAb+ contribute to liver damage in HIV+/HCV+/HBcAb+/HBsAg- subjects. A careful monitoring for signs of previous HBV infection is needed in this kind of patients.
