Innate Immunity and Respiratory Syncytial Virus (RSV) Infection in Children

Respiratory Syncytial Virus Infection

In this project we will study the capacity for single nucleotide polymorphisms (SNP) in TLR4 gene to induce varying levels of inflammatory chemokine and cytokine production.

Effectiveness of Synagis (Palivizumab) Immunoprophylaxis in Preterm Infants With High Risk of Severe...

Respiratory Syncytial Virus Infection

Published data by the Organización panamericana de la Salud shows that Peru's mortality rate from acute respiratory infections (ARI) in infants less than one year of life is second only to Haiti (14,150/100,000). Government data reports shows a marked increase of RSV infections in Peru. "Instituto Nacional de Salud" (Peru's National Institute of Health) reports between January 1st to February 26th 2006, 62% of their positive samples corresponded to RSV. Epidemiological data from Lima-Peru, demonstrates that there is no specific season for RSV infection although some data suggest an increase in RSV activity during cold months (May to September; INS data). Clinical studies show that giving five doses of Synagis (palivizumab) resulted in serum concentrations > 30 ug/mL for >20 weeks. The aim of this post-marketing observational study is to determine the RSV hospitalization rate in high-risk infants who received Synagis (palivizumab) through the Social Security Hospitals in the context of routine clinical practice.

Respiratory Syncytial Virus Infections

The purpose of this study is to evaluate the infectivity, safety, and immunogenicity of the recombinant live-attenuated respiratory syncytial virus (RSV) vaccines RSV ΔNS2/Δ1313/I1314L or RSV 276 or placebo when delivered as nose drops to RSV-seronegative infants and children 6 to 24 months of age. This study is a companion study to IMPAACT 2018.

Music Therapy With Intubated and Sedated Pediatric Patients

Respiratory Syncytial Virus Infections

The study is a randomized controlled trial of pediatric patients ages birth to two years of age who are mechanically ventilated and sedated as a result of a respiratory virus. The experimental group will receive twenty minutes of live, preferred music with a board-certified music therapist and the control group will receive twenty minutes of recorded music, also preferred, both interventions conducted at bedside. Caregivers will take a pre and post survey.

Inflammatory Mediators Associated With Infection by Respiratory Syncytial Virus

Respiratory Tract InfectionsRespiratory Syncytial Virus Infections

Infection with human respiratory syncytial (RS) virus is the most common cause of hospital stay due to pediatric lower respiratory tract infection. An exaggerated immune response contributes to the pathogenesis and small children may have over reactive airways for a long time after an infection. New research has shown that polymorphonuclear leukocytes (PMNs) are stimulated by the virus. Besides fighting the infection they also cause collateral damage to the host. Among other mechanisms PMNs stimulates mucus formation that affects breathing. They also secrete enzymes, toxic proteins and free radicals that may cause harm to lung tissue and airways. The current project strives towards identifying and quantifying inflammatory mediators in sputum, urine and blood of children with severe RS-virus infection. The ultimate aim of the project is to, in detail, describe proteins contributing to the pathogenesis of the disease.

Exhaled Nitric Oxide in Respiratory Syncytial Virus (RSV) Bronchiolitis: a Pilot Study

RSV InfectionBronchiolitis

The fraction of exhaled nitric oxide (feNO) in expired air is a reliable measure of airway inflammation. Some research experiments have demonstrated stimulation of nitric oxide production in respiratory epithelial cells infected with RSV. The principal aims are to determine if the fraction of exhaled nitric oxide (feNO) is elevated in hospitalized pediatric patients with viral lower respiratory illness and to determine if there is a difference in feNO level between RSV and non-RSV infection. NO may play a role in the association between RSV, airway reactivity, and airway inflammation. This is a prospective, pilot study that will noninvasively measure feNO in children 0-4 years of age admitted to Winthrop University Hospital, as well as controls (children in the same age range without respiratory conditions and who are well enough to perform the test). Hospitalized children will be tested for RSV (enzyme immunoassay (EIA) & DFA) and via direct fluorescent antigen technique (DFA) for influenza A & B, parainfluenza, human metapneumovirus and adenovirus. Method of feNO measurement will utilize the offline options for preschool children & infants appropriate for age as described in the 2005 Joint Statement of the American Thoracic Society & the European Respiratory Society when discussing tidal breathing techniques with uncontrolled flow rate Offline exhaled air can be collected via a mouthpiece or a face mask connected to a non-re-breathing valve that allows inspiration of NO-free air from an NO-inert reservoir to avoid contamination by ambient NO. Exhaled breath samples are collected into an NO-inert bag fitted with the expiratory port once a stable breathing pattern is present. The results of all 3 groups will be compared: control, RSV positive and RSV negative samples.

Respiratory Syncytial Virus Infection

This post marketing observational study (PMOS) was conducted in Japan during the 2013-2014 and 2014-2015 Respiratory Syncytial Virus (RSV) seasons to assess the safety and effectiveness of palivizumab for the prevention of serious lower respiratory tract infection caused by RSV in participants 24 months of age and under, who have an immunocompromised medical condition (e.g., combined immunodeficiency disease, antibody deficiency, or other types of immunodeficiency; HIV infection; recovering from organ or bone marrow transplantation; on chemotherapy; on high-dose corticosteroid therapy; on immunosuppressants) or who have Down syndrome.

Evaluation of Danirixin (GSK1325756) Inhibition of CD11b Cell Surface Expression

InfectionsRespiratory Syncytial Virus

This study is to determine danirixin (GSK1325756) concentrations required to inhibit neutrophil activation in blood obtained from Respiratory Syncytial Virus (RSV)-infected children <2 years and healthy adults. The study will evaluate differences in neutrophil activation between RSV-infected children <2 years and healthy adults with escalating concentrations of Chemokine (C-X-C motif) Ligand 1 (CXCL1) and danirixin to determine if RSV-infected children and adult neutrophils are similarly activated by CXCL1 and inhibited by danirixin. This study will guide dose prediction to inhibit specific percentages of neutrophils in future pediatric RSV-infection studies. This single-center, in vitro study will consist of 2 parts. Approximately 24 subjects will be enrolled, including 12 healthy adults and 12 RSV-infected children <2 years.
