ABSTRACT
Objective To investigate the relationship among the concentration of plasma interleukin (IL)-10 and plasma IL-13 and the clinical therapeutic effect in patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD).Methods Thirty-six AECOPD inpatients were enrolled in this study.Blood samples of the subjects were collected as soon as hospitalization, and plasma IL-10 and IL-13concentrations were analyzed by enzyme-linked immunosorbent assay.The clinical manifestations of subjects were quantified by a special designed score standard, and were evaluated at the time points of hospitalization, 48 hours treatment and 96 hours treatment.The therapeutic effect was evaluated by clinical manifestations score combined with pulmonary ventilation functional parameter.Eventually, the correlation among the concentration of IL-10 concentration and IL-13 and the clinical therapeutic effect were analyzed.Results The correlation coefficients between clinical manifestations score decrease and pulmonary ventilation function improvement with plasma IL-10 concentration after 48 hours treatment were 0.85 and 0.48 respectively,then, 0.64 and 0.52 after 96 hours treatment.The correlation coefficients between clinical manifestations score decrease and pulmonary ventilation function improvement with plasma IL-13 concentration after 48hours treatment were -0.41 and -0.34, after 96 hours treatment , correlation coefficients between clinical manifestations score decrease with plasma IL-13 concentration was -0.36.All of the above correlation coefficients were statistically significant.Conclusion Plasma IL-10 concentration was positively, whereas, IL-13 concentration was negatively correlated with the therapeutic effect in AECOPD patients.
