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
