Abstract:
Objective:To analyze the adverse reactions of patients with multidrug-resistant pulmonary tuberculosis treated with linezolid, and to provide reference for clinical rational use of drugs.Methods:A total of 189 patients with multidrug-resistant pulmonary tuberculosis who were admitted to Hunan Chest Hospital between June 2019 and June 2020 were retrospectively included, and were divided into the linezolid group and the control group. The control group was given a standardized anti-tuberculosis treatment without linezolid, and the linezolid group was given linezolid in addition to standardized regimens. The occurrences of hematological toxicity, peripheral neuritis, optic neuritis and other adverse reactions in the two groups after anti-tuberculosis treatment were recorded. The risk factors for adverse reactions of linezolid were analyzed. Statistical analysis was performed using independent samples t test and chi-square test, and logistic regression was used to analyze the risk factors for adverse reactions of linezolid. Results:A total of 189 patients with MDR-TB were included in this study, including 108 in the linezolid group and 81 in the control group. There were no significant differences in baseline characteristics between the linezolid and control groups. The frequencies of leukopenia, anemia, thrombocytopenia, peripheral neuritis and optic neuritis in the linezolid group were 20.4%(22/108), 47.2%(51/108), 21.3%(23/108), 20.4%(22/108) and 13.9%(15/108), respectively, which were all significantly higher than those in the control group (8.6%(7/81), 27.2%(22/81), 9.9%(8/81), 1.2%(1/81) and 4.9%(4/81), respectively), and the differences were all statistically significant ( χ2=4.90, 7.86, 4.40, 15.86 and 4.10, respectively, all P<0.050). Patients older than 45 years of age was independent risk factor for leukopenia (odds ratio ( OR)=3.08, 95% confidence interval ( CI) 1.03 to 9.25, P<0.050) and thrombocytopenia ( OR=2.41, 95% CI 1.09 to 5.35, P<0.050) after linezolid administration. The higher value of white blood cell at baseline ( OR=0.48, 95% CI 0.30 to 0.76, P=0.002) was an independent protective factor for leukopenia associated with linezolid. Conclusions:Pancytopenia, peripheral neuritis and optic neuritis are prone to appear when linezolid is used to treat patients with multidrug-resistant pulmonary tuberculosis. In clinical practice, closely monitoring the adverse reactions during the use of linezolid for anti-tuberculosis treatment is needed.
