Abstract:
Objective To investigate immune changes in patients with chronic obstructive pulmonary disease during exacerbations(ECOPD).Methods A randomized,prospective clinical trial was done in 65 patients with ECOPD from Feb.2004 to Oct.2004.They were divided into two groups:one group with general treatment and another with general treatment plus Pidotimod which was given 800mg orally twice daily for 15 days and then 800mg orally once daily for 15 days.Twenty healthy individuals sevred as the control.Levels of CD_ 14 、CD_ 158b 、CD~+_3、CD~+_4、CD~+_8、CD~+_4/CD~+_8 in peripheral blood were measured by flow cytometry at baseline(D1)and then again at(D15)and at the end of treatments(D30),in the meanwhile clinical picture was observed to evaluate patients' conditions.Results Totally 60 patients completed the trial correctly(30 in pidotimod group and 30 in control group).The two groups were satistically homogeneous.The positive rate of sputum bacteriological examination was 42.67%.On D1,the percentage of CD_ 14 、CD_ 158b in two groups was not different from healthy volunteers.On D15,the above immunologic parameters of the control group was decreased compared with pidotimod group,and CD_ 14 was satistically low(P
