Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Crohn's disease is more common in areas of the world with less sunlight exposure. Sunlight is a major source of vitamin D. There is some research to suggest that patient's with higher vitamin D levels are less likely to undergo surgeries and have better control of their disease. We intend to study the effects of high dose vitamin D supplementation in patients with vitamin D deficiency and Crohn's disease. We hypothesize that patients given high doses will have less hospitalizations, surgeries, steroid use.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Subjects are randomized to low or high dose vitamin D, and outcomes including steroid prescriptions, CD-related hospitalizations, CD-related surgeries, and the modified Harvey-Bradshaw Index are measured.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Low Dose Vitamin D

Patients will be given 400 IU cholecalciferol once daily for 30 days. \<-THIS IS THE Active Comparator Intervention. To maintain the blind, a random few will be given another round at the 30 day mark. For patients who enroll in the summer, a random few will again receive 400 IU cholecalciferol in March.

Group Type ACTIVE_COMPARATOR

Cholecalciferol 400 IU

Intervention Type DRUG

Cholecalciferol 400 IU po daily

High Dose Vitamin D

Patients will be given cholecalciferol 10,000 IU daily for 30 days. \<-THIS IS THE INTERVENTION. At that point, if their vitamin D levels remain below 50 ng/ml, the 30 day course will be repeated. For patients who enroll in the summer, levels will be rechecked in March and if \<50 ng/ml, a 30 day course will be administered.
