September 2, 2020 updated by: YooJin Lee, Keimyung University Dongsan Medical Center

Analysis of Volatile Organic Compounds in Exhaled Air in Patients With Inflammatory Bowel Disease Patients and Healthy Control

The availability of noninvasive biomarkers for diagnosis and stratification of inflammatory bowel disease (IBD) courses is lacking. Thus, the aim of this study is to evaluated the accuracy of exhaled breath volatile metabolite analysis on diagnosis and stratification of patients with inflammatory bowel disease.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Unknown

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Background: The diagnosis and differentiation of inflammatory bowel diseases (IBD) is challenging due to the absence of a gold standard diagnostic modality for confirmation. Exhaled breath volatile metabolite analysis focusing on diagnosis and differentiation of IBD is a promising approach. Thus, the aim of this study is to evaluated the accuracy of exhaled breath volatile metabolite analysis for patients with inflammatory bowel disease.

Method: A single center, prospective study of diagnostic testing will be conducted, recruiting crohn's disease (CD), ulcerative colitis (UC), and healthy controls (HC). The exhaled breath volatile metabolite will be analyzed using gas chromatography/mass spectrometry (GC-MS). The informations of patient's disease location, disease activity, laboratory parameters and current medications will be collected to determine the feasibility of exhaled breath volatile metabolite analysis.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 80 years (Adult, Older Adult)

Accepts Healthy Volunteers

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Volatile organic compounds differentiating the study groups
Time Frame: At the time of breath sampling
Volatile organic compounds analysed by GC-MS between the study groups
At the time of breath sampling

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.

Study Major Dates

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.

Primary Completion (Anticipated)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
