ABSTRACT
BACKGROUND:
Recent studies report incongruent finds regarding the addition of pegylated interferon -alpha (Peg- IFNα) to nucleos(t)ide analogues. This study was designed to compare the efficacy of Peg- IFNα and tenofovir disoproxil fumarate (TDF) combination therapy with each of the treatments separately.METHODS:
In this open-label, randomized clinical trial, treatment-naive hepatitis B e antigen (HBeAg)-negative patients were randomly assigned to three treatment groups Group A Peg- IFNα (180 mcg/week) with TDF (300 mg/day); Group B TDF (300 mg/day); and Group C Peg- IFNα (180 mcg/week). The intervention spanned 48 weeks and patients were followed up every 12 weeks. The primary end-point was HBV DNA load <20 IU/mL.RESULTS:
Groups A, B and C each comprised of 22, 23 and 22 patients, respectively. The number of patients with HBV DNA suppression in group A was significantly higher compared to groups B and C (P = 0.034). No significant difference was observed in the normalization trends of serum ALT levels between the three groups (P = 0.082). At week 48, combination therapy was significantly more effective in suppressing HBV DNA concentration to below the level of detection than TDF monotherapy (OR = 2.1, 95%CI 1.18-4.15; P = 0.034). Furthermore, a comparison between monotherapy arms revealed that both interventions had similar effects on the overall outcome (OR = 1.24, 95%CI 1.02-5.8; P = 0.062).CONCLUSION:
A Peg- IFNα and TDF combination therapy resulted in improved virologic response and was safe in HBeAg negative patients. Monotherapy with Peg-IFNα or TDF procured limited benefits in comparison. TRIAL REGISTRATION This study was registered in the Iranian Registry of Clinical Trials (IRCT20181113041635N1).Palavras-chave
