Eugen C. Campian, MD, St. Louis University

Brief Summary:
For each patient in the study, blood, and pain scores will be collected to look for markers for pain, at the start of treatment and 6 months after surgery of treatment.

Condition or disease Intervention/treatment
Interstitial Cystitis Other: Questionnaires Other: Collection of Blood samples

Detailed Description:

The study is investigator-initiated, prospective, study. There will be no change in care.

Patients who have had a diagnosis of IC made by cystoscopy and hydrodistension and still have pain will be recruited for this study.

Patients will have blood samples taken at the visit they sign the consent form and 6 months later.

The study staff will call and remind the patient of their 6 month visit.

Group/Cohort Intervention/treatment
Interstitial Cystitis
Patients with Interstitial Cystitis will be followed with Questionnaires and blood collection at 3, 6,and 12 months
Other: Questionnaires
QOL and pain questionnaires will be given to patients at 3, 6, and 12 months post surgery

Other: Collection of Blood samples
Blood for PBLs will be collected at 3, 6, and 12 months post surgery

Primary Outcome Measures :
  1. Change From Baseline in Pain Scores on the Visual Analog Scale at 6 months [ Time Frame: 3 months ]
    S1PR1 levels in PBLs can discriminate patients with Interstitial Cystitis pain and patients with other types of pain.

Biospecimen Retention:   Samples With DNA


Using immunoblotting, we will determine if the level of S1PR1 expression in peripheral blood leukocytes (PBLs) is increased in patients with IC pain. Patients will have blood samples taken, at the visit they sign the consent form 3 and 6 months later. A total of 4 teaspoons of blood will be taken for the study.
