BACKGROUND & AIMS: In hepatitis B e antigen (HBeAg) positive-HIV co-infected patients treated with combined antiretroviral therapy (cART), including tenofovir disoproxil fumarate (TDF), the rate of HBe seroconversion remains low. Whether adding pegylated interferon alfa (PegIFN) could increase the likelihood of HBeAg loss and HBe seroconversion has not been assessed.

METHODS: A 48-week PegIFN therapy was added to HBeAg positive-HIV co-infected patients on TDF and emtricitabine, or lamivudine for at least 6 months. The primary endpoint was HBV sustained response: HBe seroconversion with undetectable HBV DNA levels 24 weeks after completing PegIFN therapy (W72).

RESULTS: Fifty-one patients (49 men, median age 46 years, range: 32-65), were included. Median duration of HIV, HBV infections and TDF therapy was 10.3 (0.6-22), 9.8 (0.5-16), and 3.3 (0.5-6.8)years, respectively. Median baseline CD4 count was 506 (175-1316)/mm(3). HIV viral load was 10 PEIU/ml at W12 or a quantitative HBsAg decline <0.5 log IU/ml at W24 had 100% and 84% negative predictive values for response, respectively.

CONCLUSIONS: 48-week PegIFN additional therapy to cART including TDF did not significantly increase the HBe seroconversion rate, despite an HBeAg loss in 20% of the patients. HBe and HBs kinetics may nevertheless be of help in tailoring and optimising this strategy.
