OBJECTIVE:To observe the efficacy and safety of moxifloxacin combined with Jiehe pill in the treatment of muilt drug-resistant tuberculosis(MDR-TB). METHODS:116 patients with MDR-TB were randomly divided into control group and ob-servation group. Control group was given Moxifloxacin hyohochloride tablet 0.4 g once a day,observation group was additionally given Jiehe pill 9 g,twice a day,and 2 groups were given rifapentine,albendazole isoniazid,amikacin,pasiniazide,pyrazin-amide,p-amino salicylic acid and other conventional treatment. The treatment course for both groups was 18 months. The clinical efficacy,and T cell subsets (CD3+,CD4+,CD4+/CD8+),interferon(INF)γ,interleukin(IL)4 levels before and after 6,12 and 18 months,and incidence of adverse reactions in 2 groups were recorded. RESULTS:The total effective rate in observation group was significantly higher than control group,the difference was statistically significant(P<0.05). After treatment,CD3+,CD4+,CD4/CD8 and INF-γ level in 2 groups were significantly higher than before and gradually increased by time,and observation group was high-er than control group;IL-4 level was significantly lower than before and graually decreased by time,and observation group was lower than control group,the differences were statistically significant(P<0.05). There was no significant difference in the inci-dence of adverse reactions(P>0.05). CONCLUSIONS:Based on the coventional treatment,moxifloxacin combined with Jiehe pill has better efficacy than moxifloxacin in the treatment of MDR-TB,with similar safety.
