Abstract
BACKGROUND: Bacterial parapneumonic pleural effusions (PPEs) have high morbidity. The accurate identification of pathogens is vital for initiating the appropriate treatment. A previous study suggested that the use of blood culture bottles might improve the bacterial yield in PPEs.
OBJECTIVES: The aim of this study was to compare the culture positivity rate by the blood culture bottles and the standard culture bottles in bacterial PPEs.
PATIENTS AND METHODS: Patients diagnosed with PPEs at the Khon Kaen Hospital, Khon Kaen, Thailand, which is an endemic area of melioidosis, were enrolled consecutively and prospectively. The study period was from June first, 2012 to December 31st, 2013. The inclusion criteria were adult patients aged > 18 years, with exudative, neutrophilic parapneumonic effusion. Of the pleural fluid samples, 5 mL from all the eligible patients were collected in both blood culture bottles and the standard culture bottles. Patient baseline characteristics, laboratory results, and culture results were collected and analyzed.
RESULTS: During the study period, 129 patients met the study criteria. The bacteria-positive rate of pleural fluid culture using the standard culture bottle was 14.0%, whereas the positive rate using blood culture bottles was 24.0% (P < 0.001).
CONCLUSIONS: The blood culture bottle method is more effective than the standard culture bottle method for the detection of bacterial pathogens in PPE.
