Brief Summary:
The purpose of this secondary analysis is to identify breath signatures associated with idiopathic malodor conditions.

Condition or disease Intervention/treatment
Nutritional and Metabolic Diseases Other: Breath test

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.

Outcome Measures

Top of Page Study Description Study Design Groups and Cohorts Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. 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.


Secondary Outcome Measures :
  1. 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.
