The assessment of B-type natriuretic peptide be used as a prognositic factor for community-acquired pneumonia / 中国医师杂志

ABSTRACT

Objective@#To explore the value of B-type natriuretic peptide (BNP) be used as a prognostic factor for community-acquired pneumonia.@*Methods@#This was a multicenter, retrospective study. Data of patients hospitalized with community-acquired pneumonia during 2014/1/1 to 2015/12/31 from four tertiary hospitals were reviewed, including demographic and clinical features, and outcomes. Univariate analysis and logistic regression analysis were performed to determine risk factors for 30-day mortality. Receiver operating characteristic curves (ROCs) was performed to verify the accuracy of BNP>1 000 pg/ml, CURB-65 score and BNP>1 000 pg/ml+ CURB-65 score (B-CURB65) as 30-day mortality predictors in the study patients.@*Results@#1 786 patients hospitalized with community-acquired pneumonia (CAP) were entered into the final analysis. The 30-day mortality was 4.7%. Logistic regression analysis confirmed blood BNP>1 000 pg/ml was an independent risk factor associated with 30-day mortality of CAP patients. The area under the curve (AUC) of B-CURB65 was 0.774, which was higher than CURB-65 score (AUC=0.625, P=0.002).@*Conclusions@#Blood BNP is a valuable biomarker related to the 30-day mortality of CAP patients, which can increase the predicting accuracy of CURB-65 score.
