Sensory Sensitivity and Urinary Symptoms in the Female Population

April 11, 2016 updated by: James Clemens, University of Michigan

Bladder pain and discomfort, as well as urinary urgency and frequency, are bothersome symptoms seen frequently in the general population. Clinical diagnostic terms used to describe these symptoms include interstitial cystitis (IC), bladder pain syndrome (BPS), chronic prostatitis, and overactive bladder (OAB), but there is tremendous overlap between these entities, and the distinction between them is based more on eminence than evidence.

Pain and/or sensory sensitivity has been suspected to play a role in the pathogenesis of both bladder pain and urinary urgency/frequency. However, no previous studies have investigated whether entities such as IC/BPS and OAB might merely represent different points in a continuum of bladder sensory sensitivity. Moreover, we know of no studies that have directly compared sensory sensitivity in the bladder to global (i.e. CNS-mediated) sensory sensitivity.

In the study, a team of investigators with complementary expertise will perform a population-based study assessing bladder and overall sensory sensitivity, in a cohort of women representative of the population with respect to the entire continuum of bladder pain (from none to severe), and symptoms of urgency/frequency. These individuals will undergo urodynamics to measure sensory sensitivity in the bladder, as well as pressure pain and auditory loudness thresholds. The Specific Aims are to demonstrate: 1) sensory sensitivity in the bladder is related to sensory sensitivity elsewhere in the body, suggesting a CNS-driven mechanism, and 2) individuals in the population with greater global sensory sensitivity will display: a) more bladder pain, b) more urgency/frequency, and c) other symptoms of centrally-mediated pain states, such as pain in regions other than the bladder, fatigue, and insomnia.

Study Overview

Status

Status

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

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.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Observational

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

Yes

Genders Eligible for Study

Female

Sampling Method

Non-Probability Sample

Study Population

Group 1 will be women with a clinical diagnosis of IC/BPS or OAB, at least 18 years of age, who have had urodynamic testing performed within the preceding 6 months. All of these subjects will complete the questionnaires, mechanical sensitivity testing, and auditory sensitivity testing

Group 2 will be women recruited from the community sample, at least 18 years of age. All of these subjects will complete the questionnaires, mechanical sensitivity testing, and auditory sensitivity testing. Half of the subjects (n=30) will also undergo urodynamic testing to measure bladder sensitivity.

Description

Inclusion Criteria:

  • At least 18 years old

Exclusion Criteria:

  • 1) Neurological disease or disorder affecting the bladder; 2) Previous augmentation cystoplasty or cystectomy; 3) Systemic autoimmune disorder (such as Crohn's Disease or Ulcerative Colitis, Lupus, Rheumatoid Arthritis; 4)History of pelvic cancer (colon, bladder, uterus, ovary); 5) Current major psychiatric disorder or other psychiatric or medical issues that would interfere with study participation (e.g. dementia, psychosis, upcoming major surgery, etc); 6) Current pregnancy. These exclusion criteria will be assessed at the time of the initial telephone interview.

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. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Group 1 (Clinic Patients)
Women who have documented urinary status from surveys completed.
Behavioral: Pain sensitivity testing
Group 2 (Community Sample)
Women who have a clinical diagnosis of IC/BPS or OAB, and who have undergone urodynamic testing within the preceding 6 months as part of their routine clinical care.
Behavioral: Pain sensitivity testing
Behavioral: Urodynamic testing

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
Urodynamics
Time Frame: 1 year
Sensation, desire to void, strong desire to void, and maximum cystometric capacity
1 year
Auditory Sensory Sensitivity
Time Frame: 1 year
Sensitivity for loudness threshold will be performed using pure tone acoustic stimuli at an octave frequency of 2000 Hz and signal range from 40 to 100 dB
1 year

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

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.
November 1, 2011

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.
