Purpose: To investigate the effect of moxifloxacin on paraoxonase-1 (PON1) activity, and serum oxidative stress in patients with multiple drug-resistant tuberculosis (MDR-TB).Methods: A total ofof 130 MDR-TB patients who were treated with moxifloxacin from October 2014 to October 2010 in Eastern Medical District of Linyi People's Hospital of Shandong Province, China were randomly divided into an observation group (65 cases, moxifloxacin group) and control group (65 cases, non-moxifloxacin group). Total oxidant status (TOS), total antioxidant status (TAS), oxidative stress index (OSI), PON1 levels and treatment efficacy for groups were determined.Results: Compared with pre-treatment levels, TOS (23.3 ± 4.7 vs 13.9 ± 3.3 umol H2O2 Eq/L, t = 13.20, p = 0.00) and OSI (17.4 ± 4.8 vs 5.7 ± 1.4 U, t = 18.87, p = 0.00) of the observation group significantly decreased, while TAS (1.4 ± 0.5 vs 3.5 ± 0.7 umol Trolox Eq/L, t = 19.68, p = 0.00) and PON1 (15.5 ± 6.9 vs 31.1 ± 8.3 U/L, t = 11.65, p = 0.00) significantly increased. TOS (23.3 ± 4.7 vs 13.9 ± 3.3 umol H2O2 Eq/L, t = 7.73, p < 0.05) and OSI (16.9 ± 5.5 vs 7.4 ± 3.2U, t = 12.04, p = 0.05) reduced significantly in the control group. Moxifloxacin correlated positively with △TAS (r = 0.697, p = 0. 04) and △PON1 (r = 0.785, p = 0.01), but correlation with △TOS (r = -0.625, p = 0.01) was negative. Efficacy was significantly higher in the observation group than that in the control group (81.54 % vs 56.92 %, p =0.00).Conclusion: Oxidative stress injury in MDR-TB patients may be effectively managed by combination of moxifloxacin with anti-TB treatmentKeywords: Multiple drug-resistant TB, Moxifloxacin, Paraoxonase, Oxidative stress
