OBJECTIVE Real-time polymerase chain reaction (RT-PCR) testing is a quick sensitive method for detecting respiratory pathogens. We evaluated the diagnostic yield of RT-PCR assays and measured the effect of rapid reporting on patient care. METHODS In a controlled clinical trial, nasal wash specimens were obtained from patients <12 years of age with(More)
Acute respiratory tract infection (ARI) is a frequently occurring disease in children. It is a clinical diagnosis for which no internationally accepted diagnostic test is available. The majority of ARI is viral in origin, though diagnostic tests for viruses were rarely performed in the past. In the past 2 decades, new molecular techniques have been(More)
AIM The aim of this study was to determine the frequency of apnoeas in previously healthy young infants with acute respiratory tract infection (ARI) and correlate their occurrence with isolated micro-organisms, clinical findings, disease severity and outcome. METHODS We performed reverse transcriptase real-time polymerase chain reaction (RT-PCR) on the(More)
BACKGROUND The incidence of pertussis has been increasing worldwide. In the Netherlands, the seroprevalence has risen higher than the reported cases, suggesting that laboratory tests for pertussis are considered infrequently and that even more pertussis cases are missed. The objective of our study was to determine the frequency of pertussis in clinically(More)
OBJECTIVE Fibroblast-like synoviocytes (FLS) express decay-accelerating factor (CD55) at high levels. Recently, it was found that CD55 is a specific cellular ligand for the 7-span transmembrane receptor CD97. The objective of this study was to define the expression of this receptor-ligand pair in synovial tissue (ST) to provide more insight into the(More)
BACKGROUND The number of viral pathogens associated with pediatric acute respiratory tract infection (ARI) has grown since the introduction of reverse transcription real-time polymerase chain reaction (RT-PCR) assays. Multiple viruses are detected during a single ARI episode in approximately a quarter of all cases. The clinical relevance of these multiple(More)
BACKGROUND The relation between viral load and disease severity in childhood acute respiratory tract infections (ARI) is not fully understood. OBJECTIVES To assess the clinical relevance of the relation between viral load, determined by cycle threshold (CT) value of real-time reverse transcription-polymerase chain reaction assays and disease severity in(More)
