Cost-Effectiveness Analysis of 3 Therapeutic Schemes for Chronic Hepatitis B with YMDD Mutation / 中国药房

ABSTRACT

OBJECTIVE: To evaluate the cost-effectiveness of 3 therapeutic schemes in the treatment of chronic Hepatitis B with YMDD mutation.METHODS: 90 patients were randomly assigned into three groups the patients in Group A were assigned to receive Adefovir Dipivoxil in combination with Lamivudine for 12 weeks followed by administration of Adefovir alone for 36 weeks;Group B received Adefovir in combination with Lamivudine for 48 weeks,while Group C received Entecavir alone for 48 weeks.The cost-effectiveness of the 3 groups were analyzed.RESULTS: In the three groups(A,B,and C),the cost-effectiveness ratios for HBV DNA negative-conversion ratewere 12 685.6,15 481.3,and 31 462.2,respectively and the incremental cost-effectiveness ratios of Group B and Group C were 29 501.5 and 106 907.8 respectively as against Group A.The cost-effectiveness ratios of the three Groups(A,B,and C) for serum alanine aminotransferase normalization rate were 12 685.6,14 284.9,31 462.2 respectively,and the incremental cost-effectiveness ratios of Group B and Group C were 19 618.5 and 106 907.8 respectively as against Group A.The cost-effectiveness ratios of the three Groups(A,B,and C) for HBeAg/HBeAb seroconversion rate were 76 227.9,93 120.3,and 209 664.0 respectively,and the incremental cost-effectiveness ratios of Group B and Group C were 178 350.0 and 1 267 621.4 respectively as against Group A.In Group A,1 case showed rtA181V mutation and another one showed rtN236T mutation after 48-week treatment.CONCLUSION: Group B(ADV in combination with LAM) is more cost-effective in the treatment of chronic hepatitis B with YMDD mutation.
