Background and aim: To analyse the sensitisation profile to molecular components of mites allergens with the use of ALEX2 Allergy Explorer test in Atopic dermatitis (AD) patients. Method: The complete dermatological and allergological examination including the examination of the sensitisation to molecular components with ALEX2 Allergy Explorer testing was performed. For the statistical analysis, we used Fisher's Exact. Results and conclusion: The sensitisation to mites increases with AD severity. The central role in atopic march may play the molecular component Der f 2 and Der p 23. The results of our study confirm the important role of Der p 5 and Der p 7 in subgroup of patients suffering from bronchial asthma. The specific immunotherapy should focus on the components of NPC2 family and Der p 23 in AD patients. Our results may be helpful in planning hyposensitisation, treatment and immunotherapy.

The aim is to evaluate the sensitivity, specificity and positive predictive value of ALEX2 Allergy Explorer test in patients suffering from atopic dermatitis and reactions to egg. We compared the results of specific IgE to allergen reagents (molecular components) with reactions to egg in the open exposure test (OET) (history); the sensitivity, specificity and positive predictictive value were calculated with Fisher's Exact test. Altogether 100 atopic dermatitis patients were examined. The reaction to egg was confirmed in 19 patients (19%). We confirmed significant relation between the results of specific IgE to Gal d 1, Gal d 2, Gal d 3, Gal d 5, Gal d white and Gal d yolk and the results of the OET/history; the sensitivity is in the range 21.05–52.63%. We recommend to evaluate food allergy to egg in patients with severe atopic dermatitis even with negative specific IgE for molecular components. [ABSTRACT FROM AUTHOR]

The aim of our study is the evaluation of the relation between the sensitisation to molecular components of moulds and yeast and the occurrence of food hypersensitivity reactions in atopic dermatitis patients. The food reactions were confirmed in an open exposure test (history); the sensitisation to allergen reagents (molecular components) of moulds and yeast was confirmed with ALEX2 Allergy Explorer Multiplex examination. The relation between the sensitisation to molecular components of fungi and the food hypersensitivity reactions was evaluated with the use of Fisher's exact test. One hundred atopic dermatitis patients were included in the study (48 men and 52 women with an average age of 40.9 years). In patients with reaction to hazelnuts, walnuts, peanuts, fish and egg, the significantly higher level of specific IgE to Asp f 3, Cla h 8, Alt a 6, Alt a 1, Mala s 6 and Asp f 6 was confirmed.

The sensitivity of ALEX2 Allergy Explorer test in patients suffering from atopic dermatitis and clinical reactions to fish/shrimps was evaluated. We compared the results of specific IgE to allergen reagents (molecular components) and clinical reactions in the open exposure test (patient's history); the sensitivity was calculated with Fisher's Exact test (Rates and Confidence Intervals 95% C. I., value, lower, upper). Altogether 100 atopic dermatitis patients were examined. We confirmed significant relationship between the results of specific IgE to allergen reagents (molecular components) of fish and the results open exposure test/history; the sensitivity is in the range of 33.3% (7.49%–70.07%)–44.4% (13.7%–78.80%). We did not confirm the significant relationship between the results of specific IgE to allergen reagents (molecular components) of shrimps and the results open exposure test/history; the sensitivity is in the range of 0%–40% (5.27%–85.34%).
