Occurrence and clinical profile of the sensitization to Chenopodium in the province of Córdoba (Spain).
The sensitization to pollen from the Amarantaceae and Chenopodiaceae families is responsible for some pollinoses according to various authors. Following an aeropalynological carried out by the Botany Division of our University, we investigated the sensitization to Chenopodium in our pollinic patients in order to establish their clinical patterns. We evaluated 14 variables in Chenopodium-sensitive (CHE +) and nonsensitive (CHE -) patients; the results were analysed by using a computerized statistical programme. Of the 1,000 records reviewed, 38% corresponded to pollinic patients, of whom 8.42% were sensitive to pollen from this family. We found no significant differences between the two groups in the parameters representative of atopic features (e.g. eosinophilia, IgE). However, marked differences were indeed found in the age of appearance of symptoms, frequency of clinical pictures, origin of the patients, duration of the symptoms and evolution upon immunotherapeutic treatment not involving this antigen. These findings endow the sensitization to Chenopodium with special features which should be taken into account in choosing a specific treatment.
