Exploratory Study of Volatile Organic Compounds in Alveolar Breath (VOCs)
October 13, 2020 updated by: Mebo Research, Inc.
Retrospective Analysis of Volatile Organic Compounds in Alveolar Breath as Biomarkers of Idiopathic Malodor
The purpose of this secondary analysis is to identify breath signatures associated with idiopathic malodor conditions.

Intervention / Treatment
Detailed Description
Individuals with metabolic disorders may sporadically produce malodors despite good hygiene.
Analysis of volatile organic compounds (VOCs) helps to gain insights into medical conditions arising due to metabolic dysfunction as different metabolic pathways emit and or consume various VOCs.
These VOCs can be detected via the exhaled breath collected and analyzed with a portable breath collection apparatus.
VOC profiles will be compared with self-reported symptoms and other observations of participating subjects.

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
VOCs detected
Time Frame: 2 years
|
Expired air sample drawn principally from alveolar breath is analyzed by gas chromatography-mass spectrometry.
Chromatograms are searched against the NIST library.
The response for each analyte is normalized by using internal standards containing 1-bromo-4-fluoro-benzene.

VOC profiles will be compared with self-reported symptoms, observed exposures and other observations of participating subjects.
Volatile organic compounds differentiating the disease activity will be identified.
