NCT02214550

Brief Summary

The purpose of this study is to determine if some women with dysmenorrhea (painful periods) are at higher future risk of developing chronic pelvic pain (CPP) and if oral contraceptives (OC) can be used to reverse this chronic pain risk. Investigators will examine whether dysmenorrhea produces CPP via repetitive cross organ sensitization (COS) episodes. The use of cyclical OCs to eliminate dysmenorrhea is expected to reduce COS and decrease the risk of developing CPP.

Outcome Measures

Primary Outcomes (1)

  • Change in Participant Bladder Pain Sensitivity From Baseline.

    Score on a scale. Specifically, we used a Visual Analog Scale- 0 through 100 scale with 0 being no pain and 100 worst pain imaginable. Results from the visual analog scale (VAS) of the bladder filling test at the initial, 6 month and 12 month visits will be compared to determine if participants in each of the treatment groups had a reduction in pain. Bladder pain ratings at first urge will be used at the outcome measure.

    0 (baseline), 6 month, and 12 month visits

Secondary Outcomes (2)

  • Change in Quantitative Sensory Testing (QST) Parameters Regarding Pelvic Hyperalgesia From Baseline

    0 (baseline), 6 months and 12 months

  • Differences in EEG Recorded Cortical Activity Among Participants

    Baseline, 6 months and 12 months

Study Arms (5)

D+COS-no OC

NO INTERVENTION

Ten participants in the Dysmenorrhea + COS group will not receive an OC intervention. Monthly questionnaires will be completed for 1 yr. QST will be repeated at 6 months and 12 months. A yearly follow-up questionnaire will be completed for 5 years.

D+COS-cyclic microgestin 1/20

ACTIVE COMPARATOR

26 participants in the Dysmenorrhea + COS group will receive cyclic OC. Monthly questionnaires will be completed for 1 yr. QST will be repeated at 6 months and 12 months. A yearly follow-up questionnaire will be completed for 5 years.

Drug: cyclic microgestin 1/20

D+COS-continuous microgestin 1/20

ACTIVE COMPARATOR

26 participants in the Dysmenorrhea + COS group will receive continuous OC. Monthly questionnaires will be completed for 1 yr. QST will be repeated at 6 months and 12 months. A yearly follow-up questionnaire will be completed for 5 years.

Drug: continuous microgestin 1/20

PBS-continuous microgestin 1/20

ACTIVE COMPARATOR

26 participants in the Painful Bladder Syndrome group will receive continuous OC. Monthly questionnaires will be completed for 1 yr. QST will be repeated at 6 months and 12 months. A yearly follow-up questionnaire will be completed for 5 years.

Drug: continuous microgestin 1/20

No Intervention: Pain Discovery Aim

NO INTERVENTION

255 Reproductive-age women (18-45) will be identified and divided into 5 groups Healthy Controls Chronic Pain (Positive Controls) Dysmenorrhea (D) Dysmenorrhea with Cross Organ Sensitization (D+COS) Painful bladder syndrome (PBS)/interstitial cystitis (IC) After a screening, dysmenorrhea with COS and PBS participants will be compared with controls. Daily Diaries will be completed for 1-3 months. During the luteal phase of the participants' menstrual cycle or a predetermined time, participants will complete aim #1 testing consisting of a battery of questionnaires, bladder sensitivity testing, quantitative sensory testing (QST), a blood draw and EEG testing. All participants will also complete a yearly follow-up questionnaire for 5 years.

Interventions

Cyclic OC Use - Participants will ingest pills containing active hormones for 21 days followed by 7 days of no pills, and then the cycle will repeat

Also known as: loestrin 1/20
D+COS-cyclic microgestin 1/20

Continuous OC use - Pills containing hormones will be taken every day for 1 year

Also known as: loestrin 1/20
D+COS-continuous microgestin 1/20PBS-continuous microgestin 1/20

Limitations and Caveats

Small sample size due to higher than expected refusal of participants with DYSB to randomize to an OCP limits generalizability. As noted above, nonserious adverse events are reported as the frequency of ever reporting an event on a form, of any intensity.
