RESUMO
BACKGROUND: Seafood allergy is among one of the common food allergies. Decrease in consumption of omega-3 polyunsaturated fatty acids (PUFAs), prevalent especially in oily fish, has been proposed to contribute to the increased prevalence of allergic diseases. AIM: The aim of this study was to evaluate, in atopic dermatitis (AD) patients, the relation between the occurrence of food hypersensitivity reaction (FHR) to seafish and the occurrence of other atopic diseases and parameters. METHODS: Complete dermatological and allergological examination was performed in patients included in the study; 332 patients were examined, with the average age 26.8 years (SD 9.2 years). RESULTS: The FHR to seafish was confirmed in 11% of patients. Patients suffering from FHR to seafish suffered significantly more from sensitization to fungi (in 46%), from reactions to celery (in 34%), and from persistent eczematic lesions (in 82%). CONCLUSION: FHRs to seafish in AD patients are associated with persistent eczematic lesions and with the higher occurrence of sensitization to fungi and reactions to celery. The occurrence of bronchial asthma, rhinitis, positive family history, and onset of AD under 5 years of age is higher in patients with reactions to seafish, but the difference is not statistically significant.
RESUMO
BACKGROUND: Fungi as a source of allergen are still largely neglected in basic research as well as in clinical practice. This study aimed to highlight the impact of fungal allergens in a group of patients suffering from atopic dermatitis (AD). AIMS AND OBJECTIVES: The evaluation of the sensitization to fungi in AD patients aged 14 year and older and the evaluation of the relation of fungal sensitization to the occurrence of other atopic diseases and parameters. MATERIALS AND METHODS: All patients satisfying inclusion criteria attending our hospital between 2008 and 2017 were included in the study. The complete dermatological and allergological examinations were performed in all included patients including examination of specific immunoglobulin E, skin prick test to mixture of fungi and inhalant allergens, evaluation of asthma bronchiale, rhinitis, onset of AD, family history about atopy, duration of eczematous lesions, severity of AD. Pairs of these categories were entered in the contingency tables and the Chi-square test for relationship of these variables was performed with the level of significance set below 5%. RESULTS: Three hundred and thirty-one patients were included in the study; the average age was 26.8 years. The sensitization to fungi was recorded in 100 patients (30%). In these patients, the occurrence of asthma bronchiale, rhinitis, family history about atopy, sensitization to grass and trees was significantly higher than in patients without sensitization to fungi. We did not find any significant relation between the sensitization to fungi and the severity of AD, no relation was also found between the sensitization to fungi and sensitization to mites, animal dander, bird feather, and dust. CONCLUSION: The occurrence of asthma bronchiale, rhinitis, family history about atopy, sensitization to grass and trees was significantly higher in AD patients with sensitization to fungi. No relation was found between the severity of AD and the sensitization to fungi.
RESUMO
AIM: The evaluation of soy allergy in patients over 14 years of age suffering from atopic dermatitis. The evaluation of the correlation to the occurence of peanut and pollen allergy. MATERIALS AND METHODS: Altogether 175 persons suffering from atopic dermatitis were included in the study: Specific IgE, skin prick tests, atopy patch tests to soy, history and food allergy to peanut and pollen allergy were evaluated. RESULTS: The early allergic reaction to soy was recorded in 2.8% patients. Sensitization to soy was found in another 27.2% patients with no clinical manifestation after soy ingestion. The correlation between the positive results of examinations to soy and between the occurence of peanut and pollen allergy was confirmed in statistics. CONCLUSION: Almost one third of patients suffering from atopic dermatitis are sensitized to soy without clinical symptoms. The early allergic reaction to soy occur in minority of patients suffering from atopic dermatitis.
