STUDY OBJECTIVES Evaluation of a newly available rapid (15 min) immunochromatographic membrane test (ICT) to detect Streptococcus pneumoniae in urine samples, in order to assess its utility in the diagnosis of bacteremic and nonbacteremic pneumococcal pneumonia. DESIGN Retrospective study. SETTING We studied urine samples from 51 patients with(More)
We evaluated the T-SPOT.TB and Quantiferon-TB Gold In tube (QFN-G-IT) tests for diagnosing Mycobacterium tuberculosis infection. T-SPOT.TB was more sensitive than QFN-G-IT in diagnosing both active and latent infection. Both gamma interferon tests were unaffected by prior Mycobacterium bovis BCG vaccination. Among children who were not BCG vaccinated but(More)
OBJECTIVE Performance of IFN-γ assays in children is compromised. Therefore, we investigated the utility of IP-10 for the detection of active tuberculosis (TB) and latent tuberculosis infection (LTBI) diagnosis in children; comparing its positivity with QuantiFERON-TB Gold In-Tube (QFN-G-IT) and T-SPOT.TB. METHODS We studied 230 children from three(More)
We evaluated an immunochromatographic assay detecting pneumococcal antigen in urine samples from children diagnosed with pneumococcal pneumonia. The sensitivity and specificity of the immunochromatographic test with nonconcentrated urine (NCU) were 86.7 and 62.9%, respectively; with concentrated urine (CU), they were 100 and 11.7%, respectively.(More)
The purpose of this study was to evaluate the GenoType MTBDRplus assay (Hain Lifescience GmbH, Nehren, Germany) for its ability to detect resistance to rifampin (RIF) and isoniazid (INH) in Mycobacterium tuberculosis clinical strains and directly in clinical samples. A total of 62 clinical strains characterized with the Bactec 460TB system were included.(More)
BACKGROUND Lower respiratory tract infection is the most common infection leading to unnecessary antibiotic treatment in children. Etiologic diagnosis is not immediately achieved, and the pathogen remains unidentified in a large number of cases. Neither clinical nor laboratory factors allow for a rapid distinction between bacterial and viral etiology. The(More)
Infectious complications in neutropenic patients are a major cause of morbidity and mortality. Clinical signs are unspecific and fever can be attributed to other causes. Inflammatory biomarkers have emerged as potentially useful in diagnosis of bacterial and fungal infection. Levels of several biomarkers were measured in patients with hematological(More)
BACKGROUND Clinical decision rules (CDRs) could be helpful to safely distinguish between bacterial and aseptic meningitis (AM). OBJECTIVE To compare the performance of two of these CDRs for children: the Bacterial Meningitis Score (BMS) and the Meningitest. DESIGN Secondary analysis of retrospective multicentre hospital-based cohort study. SETTING Six(More)
OBJECTIVE To validate procalcitonin (PCT) level as the best biological marker to distinguish between bacterial and aseptic meningitis in children in the emergency department. DESIGN Secondary analysis of retrospective multicenter hospital-based cohort studies. SETTING Six pediatric emergency or intensive care units of tertiary care centers in 5 European(More)
