Background. Juniperus sabinoides (JS), belonging to Cupressaceae family and especially spread in the meditteranean area, causes severe respiratory tract allergies. Objective. From January 2001 to December 2003 we performed a retrospective study on JS sensibilization togheter with an aerobiological remark on its pollen concentration, in a zone located in North-West of Rome. Methods. We tested 72 patients which were given a specific serum IgE assay to JS and Cupressus sempervirens (CS). Results. Aerobiological data show a JS pollen concentration peak during February and March, and only in 2002 an increased concentration in October and November in which JS pollination takes place. Moreover in March 2003 we observed afar higher JS pollen peak than other studied year. Sensitization JS degree was 59.7% (43/72), with a clear increased of IgE specific assay request in 2003. Because of cross-reaction between JS and CS pollens, our patients, except in 2 cases, were sensitized to both, showing in 36 subjects a higher positivity class for JS than to CS. Greatest number of sensitized patients was pointed out in October-November (32.5%), JS pollination months. Conclusions. In conclusion JS pollen seems to be a rising allergen in the examined zone and we suggest to clinicians, when observing specific symptoms and for a complete diagnostic follow-up, to request a CS IgE specific assay always in combination with a JS one.
