Trial Title: The Role of Vitamin D in Chronic Urticaria and Angioedema Treatment

Study Design Characteristics:
- Allocation: RANDOMIZED
- Intervention Model: PARALLEL
- Observational Model: None
- Primary Purpose: TREATMENT
- Time Perspective: None
- Masking: DOUBLE
- Phase: None
- Number of Arms: 2.0

Eligibility Criteria:
Inclusion Criteria:~* 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).~Exclusion Criteria:~* Subjects will be excluded if:~  1. They are not capable of answering the questionnaire.~ 2. 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.~ 3. 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.~ 4. Subjects with any clinically significant abnormality in biochemistry testing, and/or hypercalcemia (calcium \> 10.3 mg/dl) or renal insufficiency (GFR\< 50 ml/min).~ 5. Subjects with a history of primary hyperparathyroidism, renal tubular acidosis, sarcoidosis, granulomatous disease, or malignancy.
