Association of Transcutaneous Pulse CO-oximetry With Inflammatory Lung Diseases (COOX)

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT02831348
Recruitment Status : Unknown

Brief Summary:
This is a pilot cross-sectional study of measured transcutaneous CO-oximetry in children with inflammatory and non-inflammatory conditions.

Condition or disease
Asthma Allergic Rhinitis Cystic Fibrosis Pneumonia

Detailed Description:

Children and young adults age 6-24 with the following conditions: asthma, pneumonia, allergic rhinitis, cystic fibrosis, and well child (without inflammatory illness) will be recruited.

Subjects will be asked to complete a brief screening survey to determine if they meet inclusion criteria. Enrolled subjects will be asked to complete questionnaire forms to characterize their health, current symptoms, medications, and common exposures. Transcutaneous carboxyhemoglobin will be recorded.

This study is cross-sectional and will only require one visit coinciding with the clinical visit. Analysis will determine the pairwise differences in SpCO between conditions tested.

Uncontrolled asthma
Indicated by an asthma control test (ACT) score of <20 and asthma symptoms of cough, wheeze, or chest tightness for more than 2 days in the prior 2 weeks, OR current asthma exacerbation indicated by the prescription of a short course (3-5 days) of systemic corticosteroids by treating provider at the time of visit.
Controlled asthma
Indicated by an ACT score of >19, or spirometry results within 10% of year's best value (based on FEV1).
Indicated by an admission diagnosis of pneumonia with chest X-ray consistent with the diagnosis, based on attending radiologist's interpretation.
Controlled allergic rhinitis
Indicated by a rhinitis control assessment test (RCAT) score of >= 21.
Uncontrolled allergic rhinitis
Indicated by an RCAT score of <21.
Cystic fibrosis (exacerbated)
Indicated by treating physician's assessment of cystic fibrosis respiratory exacerbation within 24 hours of initial antibiotic therapy.
Cystic fibrosis (stable)
Indicated by diagnosis of cystic fibrosis with baseline symptoms and with spirometry results (based on FEV1) within 5% of year's best value.
Indicated by a negative history of any of the conditions characterizing the other groups.

Primary Outcome Measures :
  1. SpCO comparison: uncontrolled asthma v. other groups [ Time Frame: Time of visit ]
    A pairwise comparison of mean SpCO will be performed between asthma exacerbation group and each other group, e.g., asthma exacerbation v. stable asthma, asthma exacerbation v. pneumonia, etc. An independent t-test will be used to determine statistical significance of the difference of means.
