ABSTRACT
Objective To detect plasma interleukins-35 (IL-35 )level in the patients with active tuberculosis complicated with bronchiectasis and to analyze its clinical significance.Methods Peripheral blood of patients with active tuberculosis from depart-ment of Dongguan 6th People′s hospital were collected,assigned to the active tuberculosis complicated with bronchiectasis group and active tuberculosis group.The healthy volunteers served as the control group.The plasma IL-35 level was measured by ELISA, and peripheral blood neutrophils and lymphocytes were detected by hematology analyzer.Results The levels of plasma IL-35 signif-icantly increased in both patients with active tuberculosis complicated with bronchiectasis and patients with active tuberculosis.The level of plasma IL-35 of patients with active tuberculosis complicated with bronchiectasis was significantly higher than that of the patients with active tuberculosis.The absolute value and percentage of peripheral blood neutrophils of patients with active tubercu-losis complicated with bronchiectasis were significantly higher than those of healthy volunteers.However,the percentage of periph-eral blood lymphocytes of patients with active tuberculosis complicated with bronchiectasis was significantly lower than that of healthy volunteers.Pearson correlation analysis showed that the absolute value of peripheral blood neutrophils of patients with ac-tive tuberculosis was positively correlated to the level of plasma IL-35.Conclusion IL-35 may play an important role in the progres-sion of active tuberculosis complicated with bronchiectasis.The determination of IL-35 may be helpful to the diagnosis of patients with active tuberculosis complicated with bronchiectasis.
