Exploratory Study of Relationships Between Malodor and Urine Metabolomics

This study is ongoing, but not recruiting participants.
University of Alberta

Mebo Research, Inc. Identifier:
First received: February 3, 2016
Last updated: July 7, 2017
Last verified: July 2017
The purpose of this study is to identify metabolic signatures associated with malodor conditions. The investigators will perform state-of-the art metabolomics tests and bioinformatic data mining to explore if conditions leading to malodor can be screened by metabolomic profiling of urine samples.

Further study details as provided by Mebo Research, Inc.:

Primary Outcome Measures:
  • Differences in metabolite concentrations measured by mass spectrometry, comparing urine samples from individuals with malodor issues, and age-matched healthy controls. [ Time Frame: ten months ]
    The investigators would like to validate if urine metabolomic profiling can be used for identifying key metabolomic signatures associated with malodor

Secondary Outcome Measures:
  • Correlations between urine biomarkers and frequency/severity of malodor symptoms (questionnaires) [ Time Frame: one year ]
    The investigators will comprehensively analyze the ability of metabolite levels to discriminate frequent and severe from non-severe malodor symptoms

Enrollment: 54
Actual Study Start Date: February 2016
Estimated Study Completion Date: December 2017
Estimated Primary Completion Date: September 30, 2017 (Final data collection date for primary outcome measure)
Subjects with malodor
individuals with self-reported odor issues suspected to be associated with microbial imbalance on or inside the body and inefficient metabolism as evidenced from other laboratory tests
Healthy control
individuals not complaining of uncontrollable or unpredictable malodor episodes

Detailed Description:
In this study, metabolite profiling analysis will be carried out on urine samples of individuals with malodor conditions related to metabolism inefficiencies. Metabolic profiles will be identified using the metabolomics equipment located in the NMR, HPLC and MS facilities of the Metabolomics Innovation Centre (TMIC). Multivariate statistical analyses will be used, as well as other approaches to mine complex data from heterogeneous sources.
