Résumé
Objective We make a retrospective analysis , to compare to COPD group and discuss the risk factors and the clinical features in acute exacerbation in patients with ACOS to follow-up the exacerbating frequency after regular treatment in both two groups in one year. Methods There were 56 patients with ACOS and 80 patients with COPD from 2013 to 2015 in our hospital in 30%≤FEV1<80% in the stable phase. The common data of the enrolled patients included the age,sex,smoking, and allergic rhinitis or other allergic diseases in family. We analyzed laboratory index including PaO2,PaCO2,CRP,white blood cells,IgE of serums and compared the proportion of antibiotics,system used of glucocorticoid and noninvasive ventilation in hospitalization of acute exacerbation and followed up exacerbating frequency after using ICS united LABA/LAMA. Results The age and smoking index in the ACOS group were lower than the COPD group (P < 0.05). The allergic rhinitis or other familial allergic diseases,lower age of 60,the high IgE in serum were risk factor, in ACOS. In acute exacerbation, the PaCO2,IgE and WBC in serum were higher than that of the COPD group(P <0.05). The midian length of stay in hosipital was 12 days in the ACOS group and 8 days in the COPD group. The proportion of antibiotics,systemic administration of glucocorticoid and noninvasive ventilation in hospitalization of acute exacerbation in the ACOS group were higher than that of the COPD group (P < 0.05). The exacerbating frequency was decreased after using ICS united LABA/LAMA(1.2±0.6 vs 3.8±1.3,P < 0.05)in both ACOS and COPD groups. Conclusions The allergic diseases may participate in ACOS, in which it has familial tendency. In acute exacerbation, ACOS patients had even more inflammation and faster course than COPD patients. Using ICS united LABA/LAMA can reduce exacerbating frequency in ACOS.
