The Prospective Improved Vitamin D Study for Inflammatory Bowel Disease Patients

Upon investigating the literature, despite there being a lot of medication compliance research, there was not much research catered to IBD patient medication management specifically.

Vitamin D supplementation based on immune-modulatory effects alongside its beneficial effects on bone health can lead to reduced rates of osteopenia and osteoporosis in the IBD population. In the treatment of IBD, the major patient care objectives to relieve symptoms and reduce inflammation doesn't leave much time or consideration for other aspects of patient care such as Vitamin D supplementation.

This study will investigate the gastroenterology department at LHSC to assess the current state of adherence and monitoring of Vitamin D and other medications for both Crohn's disease and ulcerative colitis patients. This will be done through a prospective cohort study of patients whose records have stated that they are not currently on Vitamin D. Through assessing overall adherence, foundational understanding of the IBD population will be obtained and the use the ASK-12 questionnaire will be validated. Once done, this would allow for a broader understanding of the patient specific factors affecting individual adherence and lay the foundation for research into ways at increasing adherence among non-adherent individuals.

The overall objective of this study is to estimate the proportion of patients that adhere to Vitamin D supplements. It is the hope that through investigations Vitamin D monitoring and adherence can be standardized at LHSC and long term osteoporosis and osteopenia complications commonly experienced by the IBD patient population can be prevented.

The central hypothesis is that Vitamin D adherence among IBD patients is low and that it is closely related to the patient's IBD disease severity. It is anticipated for this Vitamin D trend to be reversed, as patients may want to stabilize the disease condition and limit acute exacerbations prior to restarting maintenance therapy in the form of Vitamin D treatment.

A clinician as part of the gastroenterology team at Victoria Hospital or St. Joseph's Hospital (Dr. Ponich and other members of VH GI team) who is the primary healthcare contact for the recruited patient will make initial contact with potential participants. Dr. Ponich or another member of the VH GI team will approach the patient in clinic after their visit and ask a member of the research team to discuss the purpose and procedure of the study. The research team member will have the patients fill out a short-written consent form that meets the standards at LHSCRI as submitted in the WREM application. The research team member will obtain written consent from the patient.

Recruited patient's will be provided Vitamin D supplementation and be asked to take 2,000 IU/day. No additional reinforcement will be provided to these patients. At both 6- and 12-month intervals, remaining supplements will be collected, and overall adherence will be assessed. Participants will be asked to complete the EQ-5D-5L to assess their health-related quality of life and the ASK-12 Questionnaire, which will be compared to the pill counts, to determine the validity of ASK-12 among IBD patients. The Patients' IBD will be assessed by performing either a Partial Mayo or CDAI Score as well as completing a fecal calprotectin test. Additionally, participant serum Vitamin D levels will be collected to determine whether adherence to medication resulted in an identifiable increase.
