We report the clinical characteristics of peach allergy encountered in a population of peach-allergic patients. We evaluated 165 patients. The 70 peach-allergic patients were diagnosed through clinical history, the skin prick-prick test, and open oral challenge and rub tests to peach. As a pollinic control group, 95 pollen-allergic patients were also evaluated. Some 49% of the patients were male and 51% female. The mean age was 20 +/- 8 years. Oral allergy syndrome (86%) was the most common symptom, followed by contact urticaria (61%) and systemic symptoms (26%). Some 67% of the patients were allergic to peach pulp and 36% reported symptoms related to canned peach. Canned peach and pulp symptoms were statistically associated (P<0.01), and symptoms to canned peach were more frequently reported by patients with systemic symptoms (P<0.05). On evaluation of the peach-allergic patients' characteristics, three risk factors--allergy to peach pulp, allergy to canned peach, and peach allergy in non-pollen-allergic patients--were found, indicating development of systemic symptoms on eating peach. Most of the peach-allergic patients (81%) also had pollen allergy, which was linked to a higher prevalence of asthma (73%) than in the pollen-allergic patients of the control group (48%); this difference was statistically significant (P<0.01). Finally, two groups were clearly defined by the seriousness of the peach allergy--the non-pollen-allergic patients were more predisposed to the occurrence of systemic symptoms (>50%), and the pollen-allergic patients to asthma (>70%).
