CD4+ T Cell Recovery and Hepatitis B Virus Coinfection in HIV-Infected Patients from Côte d'Ivoire Initiating Antiretroviral Therapy.

Immunorecovery could be attenuated in HIV-hepatitis B virus (HBV) coinfection versus HIV monoinfection during antiretroviral therapy (ART), yet, whether it also occurs in individuals from sub-Saharan Africa without severe comorbidities is unknown. In this study, 808 HIV-infected patients in Côte d'Ivoire initiating continuous ART were included. Six-month CD4+ count trajectories and the proportion reaching CD4+ T cell counts >350/mm3, HIV-RNA <300 copies/mL, still alive and not lost to follow-up within 18 months ("optimal immunorecovery") were compared between coinfected groups. At inclusion, 80 (9.9%) patients were HIV-HBV coinfected, 40 (50.0%) of whom had high HBV-DNA viral load (VL) (>104 copies/mL). Coinfected patients with high HBV-DNA replication initiated ART with significantly lower median CD4+ T cell counts [216/mm3, interquartile range (IQR) = 150-286] compared to coinfection with low HBV-DNA replication (268/mm3, IQR = 178-375) or HIV monoinfection (257/mm3, IQR = 194-329) (p = .003). These patients had significantly faster rates of CD4+ cell count increase from baseline after adjusting for baseline age, World Health Organization stage III/IV, and CD4+ cell counts (p = .04), yet, were not more likely to exhibit optimal immunorecovery (82.5% vs. 80.0% and 77.9%, respectively) (p = .8). In conclusion, change in CD4+ cell counts after ART-initiation was accelerated in coinfected patients with high HBV DNA VLs, but this did not lead to increased rates of optimal immunorecovery.
