title: Occupational allergy to Limonium sinuatum: a case report.
abstract: Decorative flowers are known to be a cause of occupational allergy in the floral industry. The allergic manifestations induced by flowers include asthma, rhinoconjunctivitis and urticaria. We present a case of a 55-year-old woman, who has been working for the last 30 years as a gardener with various kinds of flowers, e.g., Limonium sinuatum (LS), chrysanthemum, sweet William (Dianthus barbatus) and Lilium. During the last 10 years she has developed nasal and eyes symptoms, dry cough, dyspnoea, chest tightness and wheezing. Clinical examination, routine laboratory testing, chest radiography, skin prick tests (SPT) involving common allergens, native plants pollens and leaves by the prick-prick technique, rest spirometry, methacholine challenge test and specific inhalation challenge test (SICT) were conducted. SPT results to common allergens were positive for grass pollens. SPT with native plants pollens and leaves showed a positive reaction only for LS. SICT induced an isolated early asthmatic reaction and significant increase in the number of eosinophils in the nasal lavage fluid. Additionally, significant increase in non-specific bronchial hyperreactivity was observed after SICT. To our knowledge, the presently described report is the first one of Limonium sinuatum induced occupational asthma and rhinitis in a Polish gardener.
