| Research Abstract |
We studied the prevalence of Japanese cedar pollinosis and allergen-specific IgE antibody amony young adults who were working in an office located at the central Tokyo.
Sera and questionnaires on the pollinosis symptoms were collected in April 1988 from a total of 406 employees (average age of 20.9 years). Specific IgE was determined by a fluorometric enzyme-linked immunosorbent assay. In some serum specimens, specific IgG was also determined. The following results were obtained.
1. IgE antibody prevalence was found to be 39% (159/406). 2. Groups of higher specific IgE concentrations had higher prevalence of pollinosis. 3. Twenty-one persons (38%) among 53 who had high levels of IgE (RAST 3) did not possess any symptoms of pollinosis. 4. IgG antibody concentrations correlated well with IgE antibody concentrations. 5. There was no difference in specific IgG concentrations between symptom-positives and -negatives who had high specific IgE concentrations.
