Background HBsAg kinetics during peginterferon (PEG-IFN) therapy for HBeAg-positive chronic hepatitis B (CHB) are associated with treatment response, but may also be influenced by HBV genotype. We compared the performance of two recently proposed stopping-rules across HBV genotypes.
Methods Serum HBsAg was measured in samples taken at baseline and week 12 of 202 HBeAg-positive patients treated with PEG-IFN±lamivudine for 52 weeks. Response was defined as HBeAg loss with HBV DNA<10,000 copies/mL at 26 weeks post-treatment (week 78). Two prediction rules were considered: a stopping-rule based on the absence of a decline in HBsAg levels at week 12, and a stopping-rule based on an absolute HBsAg level of >20,000 IU/mL at week 12.
Results A total of 63 (31%) patients failed to achieve a decline in HBsAg, of whom 2 (3%) achieved a response (NPV 97%). Conversely, 92 (46%) had HBsAg levels >20,000IU/mL, of whom 8 (9%) achieved a response (NPV 91%). Application of the stopping-rules would have resulted in early discontinuation of therapy in 5% (2/37) and 22% (8/37) of future responders, respectively. The performance of the two stopping-rules across genotypes A through D are shown in table 1. None of the patients who failed to achieve a decline in HBsAg levels achieved HBsAg clearance, compared to 4 of the patients with HBsAg >20,000 at week 12 (24% of all with HBsAg loss, 3 genotype A, 1 D).
Conclusions The performance of recently published stopping-rules for PEG-IFN therapy of HBeAg-positive CHB depends upon HBV genotype. Absence of HBsAg decline by week 12 provided best results in patients with genotypes A and D, whereas an HBsAg level >20,000 may be more applicable to patients with B and C.
