Abstract
Objective To study the effect of moxifloxacin in the treatment of patients with multidrug-resistant tuberculosis .Methods 96 patients with multidrug-resistant tuberculosis were randomly divided into the two groups . The observation group(n=48 cases) was treated by moxifloxacin,and the control group(n=48 cases) was treated by levofloxacin.They were treated for 12 months.3,6,12 months after treatment,sputum smears were taken,and the adverse reactions were observed .Serum vasoactive intestinal peptide ( VIP) level was measured before and after treat-ment.Results 3,6,12 months after treatment,the sputum negative rates in the observation group were 36.0%, 87.5%,95.8%,which were significantly higher than 62.5%,77.1%,83.3% in the control group (χ2 =5.12, 5.96,7.28,all P〈0.05).The total effective rate of the control group was 83.3%,which was significantly lower than 95.8%of the observation group (χ2 =5.28,P〈0.05).Serum VIP levels in the control group and observation group were (29.3 ±6.7)ng/L,(20.7 ±5.4)ng/L.After treatment,the serum VIP levels in the two groups were significant-ly decreased,and the serum VIP level of the observation group was lower compared with the control group (t=3.01, P〈0.05).During treatment,neutropenia,the incidence rates of gastrointestinal side effects ,liver damage and neuro-logical symptoms and other adverse reactions had no significant differences between the two groups (χ2 =1.56,1.74, 2.02,0.00,all P〉0.05).Conclusion Moxifloxacin is better than levofloxacin in the treatment of patients with multidrug-resistant tuberculosis. Key words: Extensively drug-resistant tuberculosis; Tuberculosis,pulmonary; Moxifloxacin
