Objective: To explore the relationship between peripheral blood serum soluble myeloid cell trigger receptor-1(sTREM-1), regulatory T cells/helper T cells 17(Treg/Th17), microRNA-99b(miR-99b) and the correlation of multi-drug resistant tuberculosis(MDR-TB) and the value of joint predictive efficacy.Methods: 79 MDR-TB patients(MDR group), 85 non-MDR-TB patients(non-MDR group) and 60 health checkups in the physical examination center(control group)admitted to Changde First Hospital of Traditional Chinese Medicine were selected from April 2017 to January 2020.The three groups of peripheral blood serum sTREM-1, Treg/Th17, miR-99b levels were compared, the multivariate Logistic regression equation was used to analyze the relationship between each index and MDR-TB, and the baseline data of patients with different therapeutic effects in the MDR group, peripheral blood serum sTREM-1, Treg/Th17 and miR-99b levels were compared, and the negative rate of patients with different peripheral blood serum sTREM-1, Treg/Th17 and miR-99b levels were compared, receiver operating characteristic(ROC) curve and area under ROC(AUC) were used to analyze each indicator predicts the value of turning negative. Results: The peripheral blood serum sTREM-1 and miR-99b levels in the MDR group were higher than those in the non-MDR group and the control group, Treg/Th17 was lower than that of the non-MDR group and the control group(P<0.05); The peripheral blood serum sTREM-1 and miR-99b levels of the non-MDR group were higher than those of the control group, and Treg/Th17 was lower than that of the control group(P<0.05); After multivariate logistic regression analysis, peripheral blood serum sTREM-1, miR-99b, and Treg/Th17 wereall the influencing factors of the occurrence of MDR-TB(P<0.05); peripheral blood serum sTREM-1, miR-99b levels werelower than those who had not turned negative, Treg/Th17 was higher than that who had not turned negative(P<0.05); those with high levels of sTREM-1 and miR-99b in peripheral blood had a lower conversion rate than those with low levels, and Treg/Th17 with high levels, the negative conversion rate was higher than that with the low level(P<0.05); by ROC curve analysis, AUC value of the combination of peripheral blood serum sTREM-1, miR-99b, and Treg/Th17 predicting the negative conversion was higher than that of the single test(P<0.05). Conclusion: Peripheral blood serum sTREM-1, Treg/Th17, miR-99b levels of MDR-TB patients show significant abnormal changes, which are closely related to the occurrence and efficacy of MDR-TB, and have certain indications for clinical MDR-TB treatment. |
