Abstract:
The authors investigated the radioallergosorbent test (RAST) for the specific IgE and the prick test with hose dust mite in 129 patients with atopic dermatitis(AD) wit4 four or more family numbers. RAST and prick test results were described according to family background of respiratory atopy(RA) and severity of AD. The results are summarized as follows : l. A comparison between the prick test results and RAST reactions gave a concordance of 88%. The prick test was more sensitive than the RAST. 2. The level of specific IgE in patients with personal history(PH) or family history(FH) of RA was significantly increased compared to those in patients with only AD. 3. In patients without PH and FH of RA, the level of specific IgE in patients with FH of AD was significantly increased compared to those in patients without FH of AD. 4. The level of specific IgE did not reflect the severity of AD. From the above results, it could be concluded that type I allergy to house dust mite is not directly related to AD and it occurs predominantly in those patients with AD wha have a predisposition to RA.
