Abstract:
Objective To analyze the importance of procalcitonin (PCT) and high-sensitivity Creactive protein (hsCRP) in assessing the severity of pneumonia and sepsis patients as well as prognostic evaluation.Methods A total of 77 patients with pneumonia complicated with sepsis were randomly (random number) selected from May 2013 to May 2016 in our hospital and 50 patients with simple pneumonia were enrolled as control group.The sepsis pneumonia patients were divided into three groups,namely sepsis group,severe sepsis group and septic shock group.The sepsis patient were further divided into survival group and death group according to the death of patient within 2 weeks.Statistics was employed to study the roles of PCT and hsCRP in evaluating the severity of pneumonia and sepsis patients as well as prognostic evaluation.Results Compared with control group,the levels of PCT and hsCRP were higher in patients of sepsis groups (P ＜ 0.05).The levels of PCT and hsCRP were gradually increased as the severity of the patient getting worse (P ＜ 0.05).The levels of PCT and hsCRP in the death group were higher than those in the survival group.The areas under ROC curve of PCT and hsCRP for diagnosis of sepsis and septic shock as the optimal cut-off point at ≥ 2 ng/mL and at ≥ 75 mg/L,had the sensitivity of 62.1％ and 81.2％,respectively,and the specificity of 89.2％ and 68.2％,respectively.Conclution PCT and hs CRP levels have a certain value in assessing the severity of pneumonia and sepsis patients as well as prognostic evaluation.
