Inflammatory Bowel Diseases | Drug: Evening Group Drug: Morning Group | Phase 4 |
The objective of this study is to determine whether the timing of drug administration to treat inflammatory bowel disease (IBD) has an effect on patient outcomes. Primary objective: Determine whether there is a difference in outcomes seen when patients are assigned to take their prescribed immunomodulator (IM) - either Azathioprine or 6-Mercaptopurine - at either a morning delivery time or evening delivery time.
The Investigator hypothesize that administration time of immunomodulators (IMs) during the day can affect the clinical outcomes in IBD patients.
Specific Aims Include:
- Determine whether morning vs. evening dosing of patients' prescribed IMs (either Azathioprine or 6-Mercaptopurine) could affect the subclinical markers of inflammation related to disease.
- Determine whether morning vs. evening dosing of patients' prescribed IMs (either Azathioprine or 6-Mercaptopurine) could affect endoscopic outcomes.
- Determine whether morning vs. evening dosing of IMs affect their biochemical side effects, as is routinely monitored as part of the patients' clinical care.
- Determine if outcomes correlate with patients' chronotype, as determined by standard questionnaires (the Owl and Lark Questionnaire and the Munich Chronotype Questionnaire).
Description of Procedures: After signing the informed consent form, subjects will be asked to answer the Inflammatory Bowel Disease Questionnaire (IBDQ), the Munich Chronotype Questionnaire (MCTQ), the Owl and Lark Questionnaire, the Harvey Bradshaw questionnaire, the RU SATED questionnaire, and a demographics survey. All six of these questionnaires are included with this IRB. Next, patients will be assigned a time (morning or evening) to self administer their prescribed medication for 10 weeks. Patients who currently take their medication in the morning will be asked to switch to an evening delivery and patients who currently take their medication at night will be asked to switch to a morning delivery. The group assigned to morning delivery time will be told to take their medication between 6am and 11am. The group assigned to evening delivery time will be told to take their medication between 6pm and 11pm. Lastly, patients will be asked to give a blood sample to test for complete blood count (CBC), comprehensive metabolic panel (CMP), C-reactive protein (CRP), methylmercaptopurine (6-MMP), and thioguanine nucleotides (6-TG). Plasma and serum isolated from the blood sample will be temporarily stored to measure inflammatory cytokines after every 20 subjects complete the study.
Within a 6-10 week window, as part of their clinical care, subjects will come in to assess their clinical status while undergoing biochemical monitoring every 2-4 weeks. Data from their endoscopic examination, if done, will also be collected.
After 10 weeks, the subjects will be asked to complete the IBDQ and Harvey Bradshaw questionnaire. In addition, a blood sample will be obtained to measure the same metabolite levels and other biochemical indications of disease as stated above. Again, plasma and serum will be isolated from the blood sample and stored.

- Thioguanine levels in blood [ Time Frame: 10 weeks post baseline visit. ]This is to examine if the intervention results in a greater level of thioguanine in the participants. If so, the participants are expected to have less symptom severity. Comparing baseline taken at visit one to visit two levels 10 weeks after intervention start.
- Harvey Bradshaw Activity Index [ Time Frame: 10 weeks post baseline visit. ]Disease Activity: >16 severe disease, 8-16 moderate disease, 5-7 mild disease, <5 remission
- Short Inflammatory Bowel Disease Questionnaire [ Time Frame: 10 weeks post baseline visit. ]Quality of Life Measure Score:1-7 (The higher the number the greater the quality of life)
- 6-Methylmercaptopurine levels in blood [ Time Frame: 10 weeks post baseline visit. ]This is to examine if the intervention results in a lower level of 6-Methylmercaptopurine in the participants. If so, the participants are expected to have less symptom severity. Comparing baseline taken at visit one to visit two levels 10 weeks after intervention start.
- Owl and Lark Questionnaire [ Time Frame: 10 weeks post baseline visit. ]Measure: Morning Type (Score 70-86), Moderate Morning Type (Score 59-69), Neither Type (42-58), Moderate Evening Type (Score 31-41), Evening Type (Score 16-30).
- Munich Chronotype Questionnaire [ Time Frame: 10 weeks post baseline visit. ]0-6 on some of the items in the original questionnaire (extreme early to extreme late chronotype).
- RU SATED Questionnaire [ Time Frame: 10 weeks post baseline visit. ]Sleep Quality Score: 0-12 (0 = Poor Sleep Health, 12 = Good Sleep Health)
