Abstract:
OBJECTIVETo evaluate the diagnostic value of serum procalcitonin (PCT) and C-reactive protein (CRP) in patients with acute exacerbation of chronic bronchitis.
METHODSThe PCT and CRP levels were detected in 56 patients with acute exacerbation of chronic bronchitis and 58 healthy control subjects.
RESULTSThe serum PCT level and positivity rate were significantly higher in the case group than in the control group (P<0.05); the serum CRP level was also significantly higher in the case group (P<0.05), but the positivity rate of CRP was similar between the two groups (P>0.05). The sensitivity, specificity, positive predictive value, negative predictive value and diagnostic accuracy rate of PCT were higher than those of CRP.
CONCLUSIONSerum PCT is more sensitive than CRP in the diagnoses of acute exacerbation of chronic bronchitis, and can be used as a specific indicator for monitoring the condition of the patients.
