About this study
Official title: A Prospective Study Measuring Exhaled Nitric Oxide Levels in Infants and Young Children Admitted to the Hospital for Respiratory Syncytial Virus (RSV) or Other Viral Lower Respiratory Tract Infections
The fraction of exhaled nitric oxide (FeNO) in expired air is a reliable measure of airway inflammation and has been used as a marker in asthma and other respiratory illnesses such as primary ciliary dyskinesia, bronchopulmonary dysplasia (BPD), liver cirrhosis, chronic obstructive pulmonary disease (COPD), cystic fibrosis (CF). Although, some exquisite bench research experiments have demonstrated stimulation of nitric oxide production in respiratory epithelial cells infected with RSV, there is a paucity of clinical data regarding levels of feNO in viral respiratory illness and specifically RSV.
The investigators conducted a pilot study from the fall of 2007 until October of 2009, looking at FeNO levels in RSV infected patients and compared it to non-RSV viral infections. The investigators recruited a total of 28 RSV positive and 1 RSV negative subjects, as well as 4 control subjects. The investigators found FeNO values not statistically significant between the study group (the two-tailed p=0.09, considered not quite significant), but there was a trend of higher FeNO values in the non-RSV group when compared to the RSV group. A larger sample may detect a statistically significance between these 2 groups.

Objectives:
- To determine if the fraction of exhaled nitric oxide (feNO) is elevated in hospitalized pediatric patients with viral lower respiratory illness when compared with normal subjects without respiratory symptoms. ii. To determine if there is a difference in feNO level between RSV and non-RSV infection in hospitalized pediatric patients with viral lower respiratory illness.
Method of feNO measurement utilized 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.
The investigators plan that our sample sizes for the RSV+ and control groups will be, by design, three times as large as the RSV- group. In order to achieve 80% power, the investigators will then require 45 control and 45 RSV+ patients, and 15 RSV- patients

|---|---|---|
| RSV positive subjects | Subjects admitted to Winthrop University Hospital with lower viral respiratory infection and RSV positive status by DFA and/or Viral culture | |
| RSV negative subjects | Subjects admitted to Winthrop University Hospital with a lower viral respiratory infection and RSV status negative by DFA and viral culture. these subjects may be positive for other viruses detected by DFA or viral culture (Adenovirus, Influenza A or B, Metapneumovirus or parainfluenza) or not | |
| Control group | Children in the same age range without respiratory conditions and who are well enough to perform the test from the out patient setting |

Questions about this trial
What is this clinical trial studying?
An observational study of Bronchiolitis and Infection, run by NYU Langone Health at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 2 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: withdrawn, as of the sponsor's last update on 16 Mar 2020. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study was withdrawn before enrolling participants, so there are no results.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
To determine if the fraction of exhaled nitric oxide (feNO) is elevated in hospitalized pediatric patients with viral lower respiratory illness when compared with normal subjects without respiratory symptoms (time frame: 1 year). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT01098227, which also lists 11 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 16 Mar 2020.
