Sažetak
The difference of test results between patients with »pure« atopic dermatitis (AD) and »mixed« AD (with concomitant respiratory allergy, RA) was investigated in 30 AD patients. The results showed the onset of disease that mostly occur in the early infancy _15 (50%) patients had developed the disease under the age of 2 – 2/10 in »pure« AD, and 13/20 in »mixed« AD_. Twenty (66.6%) of them had a history of RA (»mixed« AD) whereas the remaining 10 (33.3%) had »pure« AD. Seventeen (56.6%) AD patients had one concomitant allergic disease, while 3 (10%) patients had two comorhid conditions (AR and AB) each. Family history was positive for atopy in 22 (73.3%) AD patients _in 14 (46.6%) patients in a first-degree relative_. Twenty-four (80%) patients had positive prick test 9/10 (90%) in »pure« AD and 15/20 (75%) in »mixed« AD, mostly for house dust (20). Positive scratch test was observed in 16 (53.3%) patients _4/10 in »pure« AD, and 12/20 in »mixed« AD_. Nineteen (63.3%) AD patients showed positive patch test reaction 5/10 in »pure« AD, and 14/20 in »mixed« AD. AD patients had higher serum IgE (21/30) than non-atopic ones but similar in »pure« AD, and »mixed« AD _7/10 (70%) in »pure« AD, and 14/20 (70%) in »mixed« AD_. Determination of CD23 marker on B-lymphocytes showed normal values in 24, and increased values in six patients 2/10 in »pure« AD, and 4/20 in »mixed« AD. The values of CD21 were decreased in 16 AD patients 6/10 in »pure« AD, and 10/20 in »mixed« AD. HLA-DR expression was normal in almost all patients. There were no statistically significant differences (p<0.05) between the »pure« AD and »mixed« AD patient groups, except for the age at onset, which was younger in the group of patients with concomitant RA. Accordingly, study results pointed to the association between AD and RA.
