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.

Cohorts and Interventions

Group / Cohort
Intervention / Treatment
Body odor
individuals self-reporting idiopathic body odor with or without bad breath
Breath samples taken from all participants, analyzed with gas chromatography mass spectrometry (GC/MS), no treatment given.
Other Names:
  • Exhaled breath metabolomics

What is the study measuring?

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.
2 years

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Correlations between breath biomarkers and self-reported observations (questionnaires)
Time Frame: 1 year
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.
1 year
