Hepatogastroenterology

At week 24, percentages of ALT normalization, HBV DNA undetectable were both higher in individualized treatment group (ITG, 57.50%, 43.75%) than that in standard treatment group (STG, 40.00%, 27.50%; p=0.027, 0.032). The superiority of HBeAg clearance and seroconversion rates in ITG maintained from treatment termination (63.75%, 56.25%) to 48 weeks follow-up (57.50%, 53.75%). At week 96 the combined response rates were 46.25% in ITG compared with 30.00% in STG (p=0.034). Furthermore, there was no statistically significant difference in relapse rates and adverse events between the two groups.

Individualized combination therapy can achieve higher antiviral response rates. In particular, it can accelerate undetectable HBV DNA and elevate HBeAg clearance/seroconversion rates to a greater degree than Peg-IFNa-2a monotherapy.
