Observation on pollinosis with vegetable food allergy

Abstract

Objective: To investigate the incidence of plant food allergy in patients with pollinosis and the effect of food allergens on the clinical symptoms of pollinosis patients. Method: A total of 40 patients with pollinosis and food allergy attended to the allergy Department of Duolun People's Hospital of Inner Mongolia were accepted skin prick test of inhaled allergens while the rhino conjunctivitis quality of life questionnaire(RQLQ) were also completed. The patients were divided into A and B groups randomly. Patients in group A were required for avoiding allergic plant foods intake but not them in group B. The two groups of patients with RQLQ, VAS and clinical symptom scores were statistically analyzed by P<0.05, the difference was statistically significant. Result: Forty cases were allergic to Artemisia. The most common allergic plant foods was peach, which accounted for 47.5%. Twenty-four patients were allergic to multiple foods simultaneously. Seventeen cases of pollinosis were preceded by food allergy, and 23 cases of food allergy were preceded by pollinosis. The mean values of RQLQ, VAS and symptom scores in group A were 81.44±14.31, 6.02±1.39, 10.60±3.68, respectively. The mean values of group B patients after 1 years were 100.73±21.66, 8.30±1.00, 13.45±3.51, the difference was statistically significant (P<0.01). The patients in group A complained that the symptoms were better than before. The mean values of RQLQ, VAS and symptom scores before intervention were 105.2±26.69, 7.00±1.71, 14.83±3.66, with significant difference (P<0.01). There was no significant improvement in the symptoms of Group B patients (P>0.05). Conclusion: Patients with pollinosis are often associated with food allergies. Reducing the intake of allergic plant foods should help alleviate symptoms.
