pulmicort and Angioedema

Inhaled corticosteroids are widely used in allergic asthma and rhinitis. They are most often used alone or sometimes in association. Allergic side-effects of inhaled corticosteroids are less frequent than those of topical corticosteroids. We report a case of a connubial dermatitis to a budesonide spray.. A 3-year old boy was treated for asthma by budesonide (Pulmicort) and terbutaline (Bricanyl) aerosols with an inhalation chamber (Babyhaler). From the fourth day of treatment onwards, his mother had swollen and itchy lesions on the face with conjunctivitis several hours after the administration of the corticosteroids using the inhalation chamber. The last eruptions were marked by extensive lesions. The patient reported a worsening of her eruption when she was treated with a desonide cream (Tridesonit). Prick-tests conducted later on confirmed the contact allergy to budesonide and Pulmicort spray. They were also positive for Tridesonit cream and triamcinolone acetonide. Repeated open application tests with a 17-butyrate hydrocortisone cream (Locoid) for three weeks remainded negative.. Our observation is original: allergic contact dermatitis to inhaled corticosteroids is rare, the clinical presentation mimicked angioedema although it was a delayed-type hypersensitivity, hypersensitivity was limited to group B corticosteroids and it was in fact a connubial contact dermatitis.

Inhaled corticosteroids may cause various adverse effects ranging from irritation to severe anaphylactic reactions and systemic contact dermatitis. We report a 43-year-old woman who developed sore throat, swelling of the lips and oral cavity and dysphagia, 2 weeks after the use of budesonide spray (Budefat) for treatment of bronchial asthma. The symptoms occurred with a delay of 3-4 h after the treatment x2 daily. There were no immediate reactions on prick and intracutaneous testing with the commercial product used by the patient. However, marked pruritic infiltration developed within 24 h, progressing to coalescing eczematous lesions over the following 2 days. In addition, severe oedema of the right upper eyelid was observed. On patch testing, budesonide was strongly positive at day 2 and 3 in a concentration ranging from 1% to 10 p.p.m. (in petrolatum). Other corticosteroids of group A, B, C and D were completely negative. Repeated open application tests with amcinonide and triamcinolone acetonide cream on the ventral aspect of the upper arm were negative. Bronchial exposure to alternative sprays containing beclomethasone dipropionate (group D), fluticasone-17- propionate (D) and dexamethasone-21-isonicotinate (C) was well tolerated. In conclusion, this case is instructive, because the symptoms which developed after a short period of corticosteroid inhalation suggested a type I allergy. Testing proved a severe type IV contact allergy restricted to budesonide (group B), without cross-reactions to major corticosteroids of other groups.
