Abstract Objective To investigate the diagnostic value of serum procalcitonin (PCT) and hypersensitive C-reactive protein (hs-CRP) in acute exacerbation of chronic obstructive pulmonary disease (AECOPD). Methods From January 2016 to September 2018, according to whether the patient had fever, cough, yellow phlegm and acute attack and the increase of white blood cells and neutrophils (common manifestations of bacterial infections), AECOPD patients from Hepingli Hospital of Dongcheng District in Beijing City were divided into infection group (52 cases) and non-infection group (48 cases). Another 100 chronic obstructive pulmonary disease (COPD) patients were collected as control group. The changes of serum PCT and hs-CRP levels before and after AECOPD treatment were compared. Results The levels of serum PCT and hs-CRP in AECOPD group were significantly higher than those in COPD group, and the difference was statistically significant (P < 0.05). Before treatment, the levels of serum PCT and hs-CRP in infection group were significantly higher than those in non-infection group, and the difference was statistically significant (P < 0.05). After treatment, the levels of serum PCT and hs-CRP in infection group and non-infection group were significantly lower than those before treatment, and the level of indicators in infection group was significantly higher than that in non-infection group, the difference was statistically significant (P < 0.05). Conclusion Serum PCT and hs-CRP are valuable for the early diagnosis of AECOPD and whether the patient suffer infection, and can be used to evaluate the efficacy of AECOPD.
