Bladder Environment: Microbiome Oxygen Relationship (BEMOR)

February 19, 2018 updated by: Elizabeth Mueller, Loyola University
The purpose of this study is to characterize bladder urinary oxygen tension (BUOT) in women whose urinary microbiomes contains at least one anaerobic bacterial species versus women whose urinary microbiomes do not contain anaerobes.

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.

Detailed Description

Throughout the human body, microbial communities (microbiota) depend on their environment, including the level of oxygen (anaerobic vs. aerobic). Recently published evidence documents the existence of a female urinary microbiota (FUM) and provides evidence that the FUM differ based on lower urinary tract symptoms, i.e. no bladder symptoms, urgency urinary incontinence, and urinary tract infection1-4. Members of the FUM include bacteria that require oxygen (aerobes), those that abhor oxygen (anaerobes) and those that thrive in both conditions (facultative anaerobes)5. This last group of microbes is known to consume low levels of oxygen to maintain an anaerobic environment. Yet, virtually nothing is known about oxygen levels in bladder urine even though bladder urine oxygen tension may both affect and be affected by the FUM. Given the role oxygen levels play in other parts of the human body, the investigators request resources to investigate bladder urine oxygen levels. The study is designed to understand if BUOT levels differ in FUMs with and without at least one anaerobe, and if so, if there are any patient factors or urinary symptoms associated with certain BUOT

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 and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Female

Sampling Method

Non-Probability Sample

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.

Study record dates

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

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.
June 2, 2016

Primary Completion (Actual)

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.

Study Completion (Actual)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
