Eligibility Criteria
Inclusion
- Group 1: subjects with physician-diagnosed allergic rhinitis. Allergic rhinitis is defined by clinical symptoms of sneezing, runny nose, nasal congestion and evidence of IgE-mediated disease (allergy skin prick test positive or radioallergosorbent test \[RAST\] positive to environmental inhalants such as trees, grasses, weeds, animal dander, molds, dust mite, cockroach).
- Group 2: subjects with 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.
Exclusion
- They are not capable of answering the questionnaire.
- They are diagnosed with hereditary angioedema. Hereditary angioedema is a genetic disorder, autosomal dominant, of the C1 esterase inhibitor protein. 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.
