[Epidemiologic investigation of the pollen allergy to Cupressaceae in a population at risk for atopy].
The so-called emerging allergens have gained particular interest as causes of atopic diseases, and among these the cypress pollen. In fact, several allergens derived from the Cupressaceae family have appeared for the first time in new environments, thus causing unexpected phenomena. From May 2002 to May 2003 we have examined 560 patients who sought medical attention at the Center for allergic diseases in children. The patients came from various towns and villages from Southern Sardinia and all had undergone prick tests for inhaled allergens, irrespective of their complaints. The presenting symptoms were either respiratory (wheezing cough, rhinitis, asthma), cutaneous (eczema, nettle rash, angioedema) or ocular (conjunctivitis). All patients had a prick test for pollens (cypress, olive, wall pellitory, rag weed, composite, mix gross pollen), acari (Dermatophagoides farinae, Dermatophagoides pteronyssimus), dog and cat hair, and fungi (alternaria alternata, aspergillus fumigatus). Thirteen percent of patients (73/547) resulted allergic to cypress pollen, and three of them had a mono-allergy (4,1%). Among these, one suffered bronchospasm, rhinitis and asthma more severe in January-February associated with recurring small eczematous lesions. Another one suffered bronchial asthma during winter months and the last one complained of rhinitis and nasal itching also during winter months.
