Brief Summary
This clinical study was designed based on our hypothesis that vitamin D plays an important role in chronic urticaria and that high dose supplementation with vitamin D in subjects with chronic urticaria will improve clinical response. This clinical study will investigate our hypothesis in three Specific Aims:
- 1.Determine whether high dosing vitamin D supplementation (4000 IU/day) reduces medication usage (primary outcome) and urticaria severity score (secondary outcome) in subjects with chronic urticaria as compared to low dosing (600 IU/day).
- 2.Determine if high dosing of vitamin D (4000 IU/day) is safe and well-tolerated in subjects with chronic urticaria with or without baseline vitamin D deficiency.
- 3.Investigate whether there is an association with serum 25-hydroxyvitamin D levels, vitamin D receptor mRNA expression, and chronic urticaria severity.

Outcome Measures
Primary Outcomes (1)
Medication Usage
The Unit of Measure is Efficacy. The primary outcome of this study is to determine if vitamin D supplementation reduces the medication usage in subjects with CUA. Thus, for the outcome of reduction in pills, at 12 weeks, subjects whose pill usage decreases by 2 or more pills per day will be classified as improved. Subjects whose pill consumption did not change or increased will be classified as unchanged.
12 week intervention
Secondary Outcomes (2)
Total Urticaria Severity Score at 3 Months
3 month intervention
Number of Participants With Adverse Events
3 month study trial
Study Arms (2)
Vitamin D3 4000 IU
EXPERIMENTALSubjects will be randomized 1:1 to high dose vitamin D defined as 4000 IU per day for 3 months. Subjects will be given Vitamin D3 supplementation at 4000 IU daily.
Vitamin D3 600 IU
ACTIVE COMPARATORSubjects will be randomized 1:1 to low dose vitamin D as defined as 600 IU per day for 3 months. Subjects will be given Vitamin D3 supplementation at 600 IU daily
Interventions
Vitamin D 4000 IU per day for 3 months
Eligibility Criteria
You may qualify if:
- Subjects will be included if they have physician-diagnosed chronic urticaria and/or angioedema (CUA). CUA is defined by having urticarial wheals (hives) and/or angioedema (dermal swelling) on a daily or almost daily for more than 6 weeks. Patients with CUA also having signs of dermatographism and/or delayed-pressure urticaria will be included in the study. Subjects with history of intolerance to non-steroidal anti-inflammatory drugs will be included but warned not to take this drug class (acetaminophen will be allowed instead).
You may not qualify if:
- Subjects will be excluded if:
- They are not capable of answering the questionnaire.
- Subjects with a pure physical or allergic urticarias, and/or hereditary and acquired angioedema (C1 esterase inhibitor deficiency). These subjects will be excluded as the etiology of their disease is known.
- Pregnant or lactating women. All child-bearing women will be asked (verbally and on the questionnaire) if they are pregnant or lactating. If they answer yes, they will be excluded. As there is no risk or harm to the pregnant or lactating woman, a urine pregnancy test will not be used.
- Subjects with any clinically significant abnormality in biochemistry testing, and/or hypercalcemia (calcium \> 10.3 mg/dl) or renal insufficiency (GFR\< 50 ml/min).
- Subjects with a history of primary hyperparathyroidism, renal tubular acidosis, sarcoidosis, granulomatous disease, or malignancy.
