This study aimed to identify a broad spectrum of respiratory pathogens from hospitalized and not-preselected children with acute respiratory tract infections in the Farhat Hached University-hospital of Sousse, Tunisia. Between September 2013 and December 2014, samples from 372 children aged between 1 month and 5 years were collected, and tested using multiplex real-time RT-PCR by a commercial assay for 21 respiratory pathogens. In addition, samples were screened for the presence of Streptococcus pneumoniae 16S rDNA using real-time PCR...

BACKGROUND: Viral etiology of infection has a significant role in the long-term outcome of early-childhood wheezing. OBJECTIVE: This study examines asthma and lung function in adulthood after early-childhood wheezing induced by respiratory syncytial virus (RSV) and rhinovirus (RV). METHODS: A total of 100 children were hospitalized for a wheezing episode at less than 24 months of age from 1992 to 1993 in Kuopio University Hospital (Finland)...

AIM: To describe the epidemiology of critically ill children admitted to a pediatric intensive care unit (PICU) with acute respiratory disease. The association with intubation was analyzed for the three most prevalent viruses and in those with and without viral co-infection. METHODS: Patients admitted to the PICU (2004 - 2014) with acute respiratory disease were included. Analyses were performed utilizing each respiratory viral infection or multiple viral infections as an exposure...

Respiratory viruses are common in solid organ and hematopoietic stem cell transplant recipients and a recognized cause of significant morbidity and mortality. Epidemiology, risk factors, and attributable mortality in both populations are reviewed. In addition, virus-specific prevention and treatment options, including emerging investigational therapies, are discussed for respiratory syncytial virus, influenza, adenovirus, parainfluenza, and other respiratory viruses.

BACKGROUND: Several studies have reported a seasonal trend in the diagnosis of childhood cancer suggesting seasonal factors such as infection. The present study aimed to analyze the diagnosis pattern of childhood malignant diseases using public health data, and to compare this pattern with seasonal viral infection trends. METHOD: Using the open data source of the Health Insurance Review and Assessment Service, we extracted data regarding all patients under 21 years of age and who had any cancer, aplastic anemia or myelodysplastic syndrome between September 2009 and December 2013...

OBJECTIVES: Paramyxoviruses contribute to morbidity and mortality after lung transplant and are associated with bronchiolitis obliterans syndrome. Oral ribavirin has been used off-label for treatment of paramyxoviruses in immunosuppressed patients; however, data supporting its use for this purpose are lacking. MATERIALS AND METHODS: We conducted a retrospective review to evaluate clinical outcomes of lung transplant recipients infected with paramyxoviruses and received treatment with oral ribavirin at 2 tertiary referral centers...

Background: Respiratory virus infections (RVIs) pose a threat to children undergoing hematopoietic stem cell transplantation (HSCT). In this era of sensitive molecular diagnostics, the incidence and outcome of HSCT recipients who are hospitalized with RVI (H-RVI) are not well described. Methods: A retrospective observational cohort of pediatric HSCT recipients (between January 2010 and June 2013) was assembled from 9 US pediatric transplant centers. Their medical charts were reviewed for H-RVI events within 1 year after their transplant...

We investigated the occurrence of infectious pathogens during an outbreak of bovine respiratory disease (BRD) in a beef cattle feedlot in southern Brazil that has a high risk of developing BRD. Nasopharyngeal swabs were randomly collected from steers ( n = 23) and assessed for the presence of infectious agents of BRD by PCR and/or RT-PCR assays. These included: Histophilus somni, Mannheimia haemolytica, Pasteurella multocida, Mycoplasma bovis, bovine respiratory syncytial virus (BRSV), bovine coronavirus (BCoV), bovine viral diarrhea virus (BVDV), bovine alphaherpesvirus 1 (BoHV-1), and bovine parainfluenza virus 3 (BPIV-3)...

There are no approved vaccines or virus-specific treatments for human parainfluenza viruses (PIVs), which have recently been reclassified into species human respirovirus 1 and 3 and human rubulavirus 2 and 4 These viruses cause morbidity and mortality in immunocompromised patients including those undergoing hematopoietic cell transplant (HCT). No small-animal models exist for non-invasive imaging of respiratory viral infection in the HCT host despite the utility such a system would offer to monitor prolonged infection, its clearance, and treatment options...

Respiratory viral infections may cause serious complications for older adults, including residents of long-term care facilities (LTCFs). Although influenza is the most common cause of viral respiratory infections among older adults, several other respiratory viruses also cause significant morbidity and mortality, most notably respiratory syncytial virus. Other noninfluenza respiratory viral pathogens include human metapneumovirus, parainfluenza virus, rhinovirus, coronavirus, and adenovirus. All of these may cause outbreaks among LTCF residents...

The Allplex Respiratory Panel 1/2/3 (All16) is a multiplex PCR assay for detecting 16 respiratory viruses with influenza A virus (FluA) subtyping, and the first clinical assay based on multiple detection temperatures. We compared the results between All16 and Anyplex II RV16 (Any16) in 426 clinical samples. Samples showing discrepancies between the two tests were further tested using monoplex PCR. FluA subtyping based on the hemagglutinin type results of All16, which yielded H1, H3, and non-H1/H3, was compared with the results of the BioFire FilmArray respiratory panel...

The effect of glycyrrhizin on the replication of human parainfluenza virus type 2 (hPIV-2) was examined. Cell fusion induced by hPIV-2 was inhibited by glycyrrhizin, and glycyrrhizin reduced the number of viruses released from the cells. Glycyrrhizin did not change cell morphology at 1 day of culture, but caused some damage at 4 days, as determined by the effect on actin microfilaments. However, it affected the cell viability at 1 day: about 20% of the cells were not alive by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay at 1 day of culture...

INTRODUCTION: Idiopathic pulmonary fibrosis (IPF) is a chronic and ultimately fatal lung disease. One of the risk factors involved in the acquisition of IPF is viral infections, especially respiratory viruses. In the present study, we investigated the detection of respiratory viruses and the possible relationship between these viruses and IPF. METHODS: This cross-sectional study was supported by the Iran University of Medical Sciences (IUMS), Tehran, Iran. A total of 40 respiratory samples (five nasopharyngeal and 35 bronchoalveolar lavage specimens) were obtained from IPF patients referred to IUMS hospitals between April 2015 and December 2016...

BACKGROUND: Severe Acute Respiratory Infection (SARI) threatens human health and even survival, causing a huge number of hospitalized patients every year. However, as one of the most common respiratory viruses circulated worldwide, the epidemiological and phylogenetic characteristics of human parainfluenza virus (HPIV) in these cases were not well known. METHODS: A molecular epidemiological study against HPIVs infection in SARIs was performed from Sep. 2014 to Aug...

AIM: FilmArray Respiratory Panel (FilmArray RP) test is an emerging diagnostic method in fast detecting multiple respiratory pathogens; the methodology and clinical significance of FilmArray RP in community-acquired pneumonia (CAP) diagnosis were evaluated in this study. METHODS: Specimens from 74 patients with CAP were analyzed and compared using FilmArray RP, traditional multiple PCR assay, bacterial (or fungal) culture, and serological detection. RESULTS: FilmArray RP and multiplex PCR showed 100% coincidence rate in detecting coronaviruses 229E, OC43, HKU1, and NL63, human metapneumovirus, influenza A and B, and parainfluenza viruses (PIV1, PIV2, and PIV4)...

BACKGROUND: Reliance on hospital discharge diagnosis codes alone will likely underestimate the burden of respiratory viruses. OBJECTIVES: To describe the epidemiology of respiratory viruses more accurately, we used record linkage to examine data relating to all children hospitalized in Western Australia between 2000 and 2012.
