Abstract
OBJECTIVES
AND METHODS: To confirm the local production of IgE antibody from the
nasal polyp tissue, and to evaluate the difference between atopics and
non-atopics, nasal polyp tissues were taken from both 10 atopic and 10
non-atopic subjects. The tissue total IgE (tlgE) level was measured by
enzyme-linked immunosorbent assay (ELISA) and serum tlgE level by
radio-immunoassay. The tissue albumin level was measured by nephelometry, and
serum albumin level by Bromocresol green method. RESULTS: The polyp tissue
tlgE/albumin as well as serum tlgE/albumin ratio were significantly higher in
atopics than in non-atopics (p < 0.05), with no difference in the albumin level
between the two groups (p > 0.05). Three non-atopic subjects had high polyp
tissue tlgE/albumin (> 10). A significant correlation was noted between serum
tlgE/albumin and polyp tlgE/albumin (r = 0.46, p = 0.04). The ratio of polyp
tlgE/albumin to serum tlgE/albumin was greater than 1 in all of the non-atopic
subjects and 7 of 10 atopic subjects. CONCLUSION: These findings support the
hypothesis that IgE antibody could be locally produced from the nasal polyp
tissue of non-atopic subjects as well as atopic subjects. The possibility of an
isolated local production of IgE antibody was suggested.
