Procalcitonin for detecting community-acquired bacterial pneumonia

Serial procalcitonin measurements for managing community-acquired pneumonia

Procalcitonin in children admitted to hospital with community acquired pneumonia.

AIMS To assess the sensitivity, specificity, and predictive value of procalcitonin (PCT) in differentiating bacterial and viral causes of pneumonia. METHODS A total of 72 children with community acquired pneumonia were studied. Ten had positive blood culture for Streptococcus pneumoniae and 15 had bacterial pneumonia according to sputum analysis (S pneumoniae in 15, Haemophilus influenzae b i...

Diagnostic and prognostic value of procalcitonin in community-acquired pneumonia.

INTRODUCTION The value of measuring procalcitonin (PCT) in patients with community-acquired pneumonia (CAP) is unclear. The aim of this study was to determine the value of PCT as a marker for microbial etiology and a predictor of outcome in CAP patients. METHODS A single-center observational study was conducted with CAP patients. On admission, their leukocyte count, serum C-reactive protein l...

Role of C-Reactive Protein and Procalcitonin in Differentiation of Tuberculosis from Bacterial Community Acquired Pneumonia

BACKGROUND/AIMS We investigated the utility of serum C-reactive protein (CRP) and procalcitonin (PCT) for differentiating pulmonary tuberculosis (TB) from bacterial community-acquired pneumonia (CAP) in South Korea, a country with an intermediate TB burden. METHODS We conducted a prospective study, enrolling 87 participants with suspected CAP in a community-based referral hospital. A clinical...

Bacterial Pathogens Associated with Community acquired Pneumonia.

2. The use of oropharyngeal aspirate as the sample for isolation of bacterial pathogens associated with community acquired pneumonia (CAP) raises many questions. This is again highlighted by the isolation of organism like Acinetobacter and Citrobacter species from CAP cases. The value of isolating bacterial organisms that are frequently detected in the upper airways of children (eg, Streptococc...
