【Abstract】 Objective  To evaluate the correlation between the efficacy of interferon2α2
2a and the kinetics of viral load in serum1 Methods  The authors conducted a trial including 58 patients with chronic hepatitis B1Patients were treated with interferon2α22a three times a week for 6 months1 Viral kinetics were assessed by serialquantitive measurements of HBV2DNA1 Results  A significant decline of serum HBV2DNA was seen afterinterferon2α22a administration for 1 month ,the decreases were (2150 ±0144) log10 , (1162 ±1112) log10 and (1105±1135) log10 for complete responders , partial responders and no2responders , respectively1 After 1 month of treatment , HBV2DNA level was (3199 ±0191) log10 for complete responders versus (5163 ±1131) log10 for partial responders , and ( 6169 ±1142) log10 for no2responders ( P < 0105) 1 Multivariate analysis suggested that undetectable serum HBV2DNA after 1 month of interferon2α22a treatment was associated with better efficacy ; higher baseline ALT orPand no family history were also correlated with better treatment outcomes1 Conclusion  Kinetics of HBV2DNA level under interferon2α2 2a treatment are highly predictive of therapeutic response1
