Background.: Metagenomic next-generation sequencing (mNGS) has been used to uncover unusual causes of infectious diseases but has not been used routinely for the investigation of putative nosocomial outbreaks. Here, we describe the use of mNGS during investigation of a cluster of human rhinovirus (HRV)-positive infections on a high-risk pulmonary ward. Methods.: We performed mNGS on 6 midnasal turbinate swabs from 4 case-patients and 10 swabs from 9 control outpatients that tested positive for enterovirus/rhinovirus by the FilmArray system...

Upper respiratory tract infection (URI) is a nonspecific term used to describe acute infections involving the nose, paranasal sinuses, pharynx, and larynx above the vocal cords. The aim of this study was to provide a summary of the most common pathogens of URI and to compare advantages and disadvantages of traditional and new rapid microbiological tests used to identify them. Blood samples were simultaneously examined by the enzyme-linked immunosorbent assay (ELISA) and by the FilmArray Respiratory Panel for eight different pathogens in a total of 15 tests performed in nasopharyngeal swabs...

BACKGROUND: Respiratory viruses are associated with a huge socio-economic burden and are responsible for a large proportion of acute respiratory illness in hospitalised adults. Laboratory PCR is accurate but takes at least 24 h to generate a result to clinicians and antigen-based point-of-care tests (POCT) lack sensitivity. Rapid molecular platforms, such as the FilmArray Respiratory Panel, have equivalent diagnostic accuracy to laboratory PCR and can generate a result in 1 h making them deployable as POCT...

Two diagnostic bundles were compared in 127 evaluable patients admitted with community-acquired pneumonia (CAP). Diagnostic modalities in all patients included cultures of sputum (if obtainable) and blood, urine for detection of the antigens of Streptococcus pneumoniae and Legionella pneumophila, and nasal swabs for PCR probes for S. pneumoniae and Staphylococcus aureus. At least one procalcitonin level was measured in all patients. For virus detection, patients were randomized to either a 5-virus, lab-generated PCR panel or the broader and faster FilmArray PCR panel...

Rapid and definitive diagnosis of viral respiratory infections is imperative in patient triage and management. We compared the outcomes for adult patients with positive tests for respiratory viruses at a tertiary care center across two consecutive influenza seasons (winters of 2010-2011 and 2012). Infections were diagnosed by conventional methods in the first season and by multiplex PCR (FilmArray) in the second season. FilmArray decreased the time to diagnosis of influenza compared to conventional methods (median turnaround times of 1...

A broad range of viral and bacterial pathogens can cause acute respiratory tract infection. For rapid detection of a broad respiratory pathogen spectrum, multiplex real-time PCR is ideal. This study evaluated the performance of the new Luminex NxTAG Respiratory Pathogen Panel (NxTAG-RPP) in comparison with the BioFire FilmArray Respiratory Panel (FA-RP) or singleplex real-time PCR as reference. A total of 284 clinical respiratory specimens and 3 influenza A/H7N9 viral culture samples were tested. All clinical specimens were processed and analyzed in parallel using NxTAG-RPP and the reference standard method...

A state-wide pertussis outbreak occurred in Washington during the winter-spring months of 2012, concurrent with respiratory viral season. We compared performance characteristics of a laboratory-developed pertussis PCR (LD-PCR for Bordetella pertussis, Bordetella parapertussis, and Bordetella holmesii) and rapid multiplex PCR (RM-PCR) for respiratory viruses (FilmArray™, BioFire, B. pertussis data unblinded following FDA approval post outbreak). We analyzed three cohorts of patients using physician testing orders as a proxy for clinical suspicion for pertussis or respiratory viruses: Cohort 1, tested by LD-PCR for pertussis pathogens only by nasopharyngeal swab; Cohort 2, by RM-PCR for respiratory viruses only by mid-nasal turbinate swab; and Cohort 3, by both methods...

The Xpert Flu/RSV XC was compared to the FilmArray respiratory panel for detection of influenza (Flu) A, Flu B, and respiratory syncytial virus (RSV), using 128 nasopharyngeal swabs. Positive agreements were 100% for Flu A and RSV and 92.3% for Flu B. The Xpert may be useful in clinical situations when extensive testing is not required and may serve an important role in laboratories already performing broader respiratory panel testing.

The FilmArray Respiratory Panel (RP) v1.7 assay has improved sensitivity for detection of human adenovirus (HAdV), compared to an earlier version (RP v1.6). RP v1.7 was designed for detection of species B, C, and E but may show variable detection of species A, D, and F. We sought to evaluate the clinical and analytical performance of RP v1.7 for detection of HAdV in a large pediatric cohort. Respiratory specimens obtained from a tertiary care children's hospital between February 2014 and February 2015 were tested for HAdV by RP v1...

During the enterovirus D68 (EV-D68) outbreak of 2014, the BioFire FilmArray (FA) respiratory panel was used to detect rhinovirus/enterovirus in respiratory specimens; suspected EV-D68-positive specimens were sent to CDC for confirmation. Positive rhinovirus/enterovirus FA targets revealed patterns loosely associated with EV-D68 that may be useful for confirmation triaging.

The FilmArray respiratory panel (FARP) reliably and rapidly identifies 17 viruses and 3 bacterial pathogens. A nasopharyngeal swab FARP (NP FARP) is performed for many patients with respiratory symptoms. For patients who are acutely ill or immunocompromised or fail to improve, a bronchoalveolar lavage sample FARP (BAL FARP) is performed in addition to the NP FARP. To date, no studies have compared the yield of a BAL FARP with that of an NP FARP. We retrospectively studied all patients who had a BAL FARP within 7 days after an NP FARP between June 2013 and May 2014...

The etiology of community-acquired pneumonia (CAP) is determined in less than half of the patients based on cultures of sputum and blood plus testing urine for the antigens of Streptococcus pneumoniae and Legionella pneumophila. This study added nasal polymerase chain reaction (PCR) probes for S. pneumoniae, Staphylococcus aureus, and respiratory viruses. Serum procalcitonin (PCT) levels were measured. Pathogens were identified in 78% of the patients. For detection of viruses, patients were randomized to either a 5-virus laboratory-generated PCR bundle or the 17-virus FilmArray PCR platform...

BACKGROUND: Rapid multiplex polymerase chain reaction (PCR) assays simultaneously detect several respiratory viral pathogens with high sensitivity. Maximizing detection of influenza at the point of care has the potential to reduce unnecessary antibiotic use, laboratory tests and hospitalizations. However, the cost-effectiveness of rapid multiplex PCR assays for influenza has not been compared with other diagnostic methods in children. METHODS: For children presenting to the emergency department with influenza-like illness, we compared costs and outcomes using 4 different testing strategies for detection of influenza: (1) a rapid multiplex PCR platform (FilmArray); (2) traditional PCR; (3) direct-fluorescent antibody and (4) rapid antigen tests...

Acute respiratory infections, which are commonly caused by viruses, are an important cause of morbidity and mortality in children. In Argentina, national surveillance programs for the detection of respiratory viruses are usually performed by using immunofluorescence (IF) assays, although it is well known that molecular methods are more sensitive. An automated multiplex PCR device, the FilmArray-Respiratory Panel (FilmArray-RP), can detect 17 viral and 3 bacterial pathogens in a closed system that requires only 5 min of hands-on time and 1h of instrumentation time...
