Favorable Response to Long-term Nucleos(t)ide Analogue Therapy in HBeAg-positive Patients with High Serum Fucosyl-Agalactosyl IgG.

ABSTRACT: Aberrant IgG glycosylation is a feature of hepatitis B virus (HBV) infection but its effect on a long-term efficacy of antiviral therapy has never been addressed. After a screening of 1,085 patients, 132 eligible HBV e antigen (HBeAg)-positive and 101 HBeAg-negative patients with anti-HBV nucleos(t)ide analogue monotherapy were enrolled with on-treatment follow-ups for at least one year. IgG1 N-glycome was profiled using mass spectrometry and evaluated for its relevance in treatment responses. The results indicated that a high level of serum fucosyl-agalactosyl IgG1 (IgG1-G0F) at baseline was associated with the severity of liver inflammation and damage but advanced treatment responses, including HBV DNA loss, HBeAg seroconversion, a reduced drug resistance rate, and a liver histological improvement at year 1, thereby improving the long-term treatment efficacy and the probability of treatment discontinuation in HBeAg-positive patients. Stepwise Cox regression analyses revealed that baseline IgG1-G0F >30% was an independent factor that links to virological response (HR 3.071, 95% CI 1.835-5.141, P?

Project description:BackgroundPatients with chronic hepatitis B virus (HBV) infection who are hepatitis B virus e antigen (HBeAg) positive are increasingly being treated with nucleos(t)ide analogs (NUCs). However, the predictive value of serum hepatitis B virus core antibody (HBcAb) levels for HBeAg seroconversion among patients with high viral load remains unclear.MethodsThis study consisted of 74 patients with high viral load (HBV DNA >1 × 107 copies/mL) enrolled in a multicenter, randomized, controlled trial, treated with lamivudine and adefovir (N = 32) or entecavir (N = 42) for up to 96 weeks. Serum HBV DNA, quantitative hepatitis B virus surface antigen (HBsAg), HBeAg, and HBeAb was tested at each visit. Quantitative HBcAb evaluation was conducted for all the available samples in the trial, by using a newly developed double-sandwich anti-HBc immunoassay.ResultsSerum HBcAb levels were significantly higher in patients with a serum alanine aminotransferase (ALT) level more than five times the upper limit of normal (ULN) compared with patients with ALT levels within 5 × ULN (4.25 ± 0.61 vs. 3.94 ± 0.47 log10 IU/mL, P = 0.0345). Patients with HBeAg seroconversion were associated with a higher level of HBcAb at baseline, compared with those without HBeAg seroconversion (4.38 ± 0.54 vs. 4.02 ± 0.58 log10 IU/mL, P = 0.029). The area under receiver operating characteristic curve of baseline HBcAb for HBeAg seroconversion was 0.71 (95% CI: 0.55-0.86, P = 0.013). When the baseline HBcAb level was >4.375 log10 IU/mL, the sensitivity and specificity to predict HBeAg seroconversion at week 96 were 62.5% and 74.2%, and the positive likelihood ratio (LR) and negative LR were 2.42 and 0.51, respectively. The multivariate analysis result indicated that baseline serum HBcAb level was the only independent predictor for HBeAg seroconversion at week 96, with an odds ratio of 4.78.ConclusionBaseline serum HBcAb level >4.375 log10 IU/mL could satisfactorily predict HBeAg seroconversion among patients with high viral load treated with NUC.
