ABSTRACT
<p><b>OBJECTIVE</b>To investigate the relationship of virological breakthrough and production of neutralizing anti-interferon antibody (NAb) in chronic hepatitis B patients treated with recombinant interferon-alpha (rIFN-alpha).</p><p><b>METHOD</b>Four hundred eighty-five patients with histological proven chronic hepatitis B were treated with 5 MU recombinant interferon-alpha 1b (rIFN-alpha1b) thrice weekly for 6-37 months (median 10). Serum HBV DNA, HBeAg and NAb levels of the patients were detected by fluorescent-quantitative PCR, enzymoimmunoassay and antiviral neutralizing biological assay respectively during the therapy.</p><p><b>RESULTS</b>Virological breakthrough occurred in 66 patients (13.6%), and NAb was found in 98 patients (20.2%) of the total 485 patients. The rate of NAb positivity was higher in patients with viral breakthrough than those without it (68.2%, 45/66, vs 12.6%, 53/419, chi(2)=109.06, P < 0.01), and viral breakthrough occurred more in patients with positive NAb than with negative NAb (45.9%, 45/98, vs 5.4%, 21/387, chi(2)=109.06, P < 0.01). The time of the viral breakthrough occurrence and the time of NAb production had a significant correlation (P < 0.01). The occurrence of viral breakthrough was also influenced by the age of patients (P < 0.05) and HBeAg status (P < 0.01) before they were treated.</p><p><b>CONCLUSION</b>Viral breakthrough occurred in 13.6% of our 485 chronic hepatitis B patients treated with recombinant interferon-alpha. Their viral breakthrough and production of NAb production had a significant correlation.</p>
