BACKGROUND & AIMS: Benefits of nucleos(t)ide analogs (NAs) on hepatitis B surface antigen (HBsAg) reduction and interferon-lambda3 (IFN-λ3) induction are still not known. This study aimed to investigate the effects of NAs on HBsAg reduction and association with serum IFN-λ3 levels in chronic hepatitis B (CHB) patients.
METHODS: A total of 91 patients [51 treated with nucleoside analog entecavir hydrate (ETV) and 40 treated with nucleotide analog adefovir dipivoxil (ADV) or tenofovir disoproxil fumarate (TDF)] with clinically evident CHB (chronic hepatitis, 57; liver cirrhosis, 34) were enrolled in this study. Serum IFN-λ3 levels among patients receiving ETV and ADV/TDF were measured before the initiation of therapy and 1, 3, and 5 years post-therapy.
RESULTS: The change (mean ± standard deviation) in serum HBsAg levels from baseline to year five was -0.38 ± 0.46 and -0.84 ± 0.64 log10 IU/ml in ETV and ADV/TDF groups, respectively (p = 0.0004). Higher serum IFN-λ3 levels were observed in ADV/TDF group compared with ETV group during treatment (p < 0.001). Serum IFN-λ3 levels showed negative correlation with HBsAg reduction in ADV/TDF group (r = -0.386, p = 0.038) at week 48. Nucleotide analogs (ADV/TDF) treatment has associated factors with -0.3 log HBsAg decline at 1 year, -0.5 log HBsAg decline at 3 years, and -0.8 log HBsAg decline at 5 years after NAs treatment on multivariate analysis.
CONCLUSIONS: Nucleotide analog (ADV/TDF) treatment reduced HBsAg levels greater compared with nucleoside analog (ETV) in parallel with IFN-λ3 induction.
