ABSTRACT
PURPOSE: We investigated the change in serum total immunoglobulin E (IgE) and allergen-specific IgE according to allergic diseases and age. METHODS: Allergic markers of children under 18 years of age with allergic diseases for the last 5 years were collected from 12 hospitals nationwide. The total data was 9,710. Data about levels of serum total IgE and allergen-specific IgE to 15 common allergens were collected. RESULTS: In children with asthma, serum total IgE was higher in older age than in younger age until age 7 to 12 years, at which time the level was highest (paper radioimmunosorbent test, 526.7 IU/mL; UniCAP, 339.9 IU/mL). The level was lower in older age than that during younger age. This change was similar to that in children with allergic rhinitis and atopic dermatitis. The level was highest at ages 7 to 12 years in children with allergic rhinitis, and at age 10 to 12 years in children with atopic dermatitis. In children with both asthma and allergic rhinitis, as well as in children with all three diseases, the change in serum total IgE was similar to that of children with an isolated disease. The highest level in children with all three diseases was higher than that in children with an isolated disease. The analysis of allergen-specific IgE positivity showed that food allergens were dominant before the age of 2 years, and that aeroallergens such as house dust mites were dominant. CONCLUSION: Serum total IgE in Korean children with allergic diseases was higher in older age than in younger age until the ages of 7 to 12 years, and then the change in total IgE by age was the opposite.

This study comprised 60 patients with ulcer and non ulcer lesions and 20 persons as a control group, with age ranging from 16-66 years. Three biopsies were taken from stomach, antrum and duodenum for pathological studies and radio- immunoassay detection of serum pepsinogens level. The results of this study showed increased level of serum PGI and high PGI/PGII ratio in cases with duodenal ulcers and duodenitis than those of control group, gastric ulcer patients and patients with gastritis. Also we found that elevated serum level of PGII with decreased PGI/PGII ratio in cases of gastric ulcer and patients with gastritis than those of control group, duodenal ulcer patients, patients with non ulcer lesions as patients with duodenitis and gastro duodenitis. Radio immunoassay of serum pepsinogens I and II are considered as a good markers for detection of early gastro duodenal lesions and they are markedly changed in established cases with duodenal or gastric ulcers

Serum IgE level and Clonorchis specific IgE in individuals with Clonorchis sinensis were determined by radioimmunosorbent(RIST) and radioallergosorbent technique(RAST) respectively. Highly significant elevations of serum IgE (P<0.001) and specific IgE antibodies (P<0.01) were observed in area from individuals with clonorchiasis. The mean values of serum IgE in individuals with clonorchiasis and healthy individuals were 2,372 IU/ml and 364 IU/ml respectively and specific IgE antibodies of both groups were 52.0 and 4.4%. A close correlation(r=0.9451) between serum IgE level and specific IgE antibodies were observed and correlation (r=0.6056) between serum IgE and EPG and between specific IgE and EPG(r=0.5693) were also observed.
