Abstract M S_”_’*_’*_a49~_&_e_u~_.f”,_~,_’_”_ SUMMARY AND CONCLUSION This study was carried out on 76 patients attending the Chest Department • Benha University Hospital. Zagazig University . They were diagnosed as having bronchial asthma. Ventilatory functions and intradermal skin testing were performed for all these patients. Ten allergens were used in skin testing which were prepared in the Microbiology and Immunology Department • Benha Faculty of Medicine • Zagazig University . These allergens were house dust • hay dust. cotton dust. pollen , mixed fungi • wool • goat hair • rabbit hair. dog hair and mixed feathers . Out of these 76 patients 33 were atopic and 43 were non atopic with equal sex proportion . It was found that the most common allergen, in the locality was house dust ( 28 cases ) then pollen ( 11 cases) then hay and cotton dust (10 cases) . 25 cases having positive skin test and abnormal ventilatory functions were subjected to testing for specific 19B of house dust by enzyme linked allergosorbent assay (EAST) . Out of them 23 cases were positive with different grades . By comparing the grades of intradermal skin test.to house dust and specific 19Blevel to the same allergen . It was found that they were closely related to each other . So • it was concluded that skin testing is sensitive test and is a cheap one , that .can be used for large number of patients and that EAST is also sensitive and specific test but has the disadvantage of being expensive. so must be used only for diagnosis of cases of suspected allergy and having negative skin testing . _________________________ GiJ |
