Abstract
Objective To investigate the correlation between serum procalcitonin (PCT) and acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) score and prognosis in acute exacerbation of chronic obstructive pulmonary disease (AECOPD).Methods A total of 88 patients with AECOPD admitted to emergency department of Peking university third hospital were prospectively studied,and were divided into three groups,namely high score group,median score group and low score group according to APACHE Ⅱ score.Serum PCT,hypersensitive C-reactive protein (hs-CRP),WBC and lactate were assayed within the first 24 hours after admission,the differences in those indicators between three groups were analyzed; and the correlation between PCT and APACHE Ⅱscore,hs-CRP,WBC,lactate were investigated.The patients were divided into survival group and death group according to prognosis,and the differences in those indicators between the two groups were analyzed.Results The serum levels of PCT was higher in high score group (0.60±0.32) ng/ml than that in median score group (0.36 ±0.23) ng/ml and that in low score group (0.24 ±0.19) ng/ml,differences between groups were statistically significant (P ＜0.01).The hs-CRP was higher in high score group M (P25,P75) 36.88 (10.14,47.16) mg/L than that in median score group 15.00 (3.64,30.33) mg/L and that in low score group 14.77 (4.35,15.80) mg/L (P =0.046).The PCT significantly correlated with APACHE Ⅱ and hs-CRP (P ＜0.01).The serum levels of PCT,APACHE Ⅱ score,hs-CRP and lactate were significantly higher in death group than those in survival group (P ＜ 0.05).Conclusions There is a good correlation between PCT and APACHE Ⅱ score in patients of AECOPD,suggesting PCT to be a sensitive predictor of prognosis. Key words: Chronic obstructive pulmonary disease; Procalcitonin; Acute physiology and chronic health evaluation Ⅱ score
