ABSTRACT
Objective To investigate the correlated clinic factors of prostecdtive efficacy and recurrence in chronic hepatitis B patients who got the combinated fully respond to Lamivudine.Methods To divide the chronic hepatitis B patients who got the combinated fully respond to Lamivudine into two groups,according to whether the curative effect was consolidated after the withdrawal of lamivudine therapy for two years.Group A was consolidated and group B was repeated.To compare the two groups correlated clinic factors.Results Consolidated ratio of prostecdtive efficacy was 64.71% in the first year,then it dropped to 55.88% in the second year.There was apparent difference between two groups which included:ages,total months of treatment,serum HBV DNA before and after treatment,ALT,time to HBeAg seroconversion and consolidation.Particularly is time stoped a medicine,the pro-s 1 Ag was negative,the HbeAg fixed amount is a 0 Ncus/ml,two all match 33 example,only 1 while stopping a medicine for 12 months relapse,two years long-term curative effect consolidation rate reaches to 97%,.But come short of twos to all match 35 example,29 HBVDNA rebound,relapse of illness,two years long-term curative effect consolidation rate reaches to 17.14% only.(P=0.0000).Conclusions To achieve the withdrawal indication after long-term antiviral therapy with nucleoside according to The Guideline of Prevention and Treatment for Chronic Hepatitis B,it still must refer to that the pro-s1Ag was negative.whether the quantitated index of HbeAg had achieved to 0Ncu/ml,otherwise,it was necessary to extend the course of treatment of antiviral therapy.The extensive course of treatment was very safe,because the ratio of mutation of YMDD and some other virus was tiny.
