To evaulate the possible pathogenetic significance of allergen-specific IgA antibody in respiratory secretion from asthmatics, we measured house dust mite(HDM)-specific IgA antibody in 3% saline-induced sputum from 23 HDM-sensitive asthmatics, 4 atopic asthmatics without mite-sensitivity, 6 non-atopic asthmatics, and 13 non-atopic, non-asthmatic controls (including 6 non-atopic healthy controls, 4 patients with chronic bronchitis, and 3 patients with rheumatoid arthritis) by ELISA. We also measured HDM-specific IgA antibody in serum and numbers of eosinophils in sputum. 1) Levels of HDM-specific IgA antibody in sputum from mite-sensitive asthmatics were significantly higher than those from non-atopic, non-asthmatic controls and non-atopic asthmatics(p<0.05). Levels of HDM-specific IgA antibody in sputum from atopic asthmatics without mite-sensitivity were significantly higher than those from non-atopic, non-asthmatic controls (p<0.05), however HDM-specific IgA/albumin raito was not significantly different between two groups (p>0.05). 2) The ratio of HDM-specific IgA antibody to albumin in sputum was not significantly different in mite-sensitive asthmatics with sputum eosinophila (> or = 5% of 200 counted leukocytes) and those without sputum eosinophilia (p>0.05). 3) The ratio of HDM-specific IgA to albumin in sputum from asthmatics was higher than that of serum. 4) There was no significant correlation of HDM-specific IgA/albumin ratios between serum and sputum (p>0.05). 5) When comparing sputum and saliva samples from 7 mite-sensitive asthmatics, levels of HDM-specific IgA antibody in sputum were significantly higher than those in saliva (p<0.05). In conclusion, HDM-specific IgA anti-body was increased in sputum from HDM-sensitive asthmatics, and it might be locally produced from bronchial mucosa. To evlauate the pathogenetic significance of allergen-specific IgA antibody in respiratory secretion from asthmatics, further studies might be needed.

BACKGROUND: Measurement of allergen-specific IgE antibodies using enzyme-linked immunosorbent assay (ELISA) has been developed and the results were shown to correlate well with those obtained by radioimmunoassay (RIA). However, consensus on the optirnal condition and data expression method for the measurement of allergen-specific IgE using ELISA is still not present. Object: To define the optimal condition for the measurement of allergen-specific IgE using ELISA and to evaluate the accuracy and reproducibility of the results, METHOD: We measured the concentrations of house dust mite-specific IgE antibodies in serum samples by ELISA and RIA method (AlaSTAT, DPC, USA) using standardized Dermatop~hagoides farinae antigen (kindly donated by Allergopharma Joachim Ganzer KG, Reinbek, Germany). RESULTS: Optirnal antigen coating amount was 2 ug/well and optimal serum dilution was 1: 10 for ELISA. The expression of the absolute concentration of house dust mite-specific IgE antibodies within the unknown sample using serial dilutions of samples and standard serum seemed to be more reasonable than the expression of absorbance value at a single serum dilution, because the former method provided better inter-assay variation and correlation with RIA results. The results of specific IgE rneasurement using ELISA significantly correlated with RIA results (r=0.96, p<0.001, n=26). CONCLUSION: These findings suggest that the measurement of allergen-specific IgE antibodies using the ELISA method can be accurate and reliable if optimal assay conditions and standardized data expression are applied.

BACKGROUND: Toluene diisocyanate (TDI) is the most prevalent agent to cause occupational asthma (OA) in Korea. The pathogenic mechanism of TDI-induced OA is still unclear. Involvement of both immunological and non-immunologicaI mechanisms have been suggested. OBJECTIVE: To evaluate a possible role of neutrophil in the development of TDI-asthma. OBJECT AND METHOD: Myeloperoxidase (MPO) as a neutrophil activation marker in both serum and induced sputum, and IL-8 in induced sputum were measured. Induced sputa and sera were collected from 15 TDI-induced OA patients (classified to group I) during TDI- bronchoprovocation test and were compared with those from 11 asthmatic subjects with negative TDI-bronchoprovocation test (group II). MPO levels were measured by radioimmunoassay, IL-8 levels, by enzyme linked immunosorbent assay and albumin levels, by nephelometry. Sputum MPO and IL-8 levels were presented as a ratio to albumin. RESULT: Serum MPO level tended to decrease during the TDI-bronchoprovocation test in two groups, but no statistical significance was reached (p>0.05). However, the ratios of MPO (the ratio of MPO level measured at 30 min to MPO level at baseline, and the ratio MPO level measured at 360 min to MPO baseline) in group I were significantly lower than group II (p=0.004, p=0.03 respectively). The IL-8/albumin and MPO/albumin levels in induced sputum from group I were significantly increased after the TDI-bronchprovocation test in comparison to the baseline value which was obtained before the bronchoprovocation test (p=0.0l, p=0.02 respectively). There was a significant correlation between the percent increase of IL-8/albumin and the MPO/albumin in induced sputum (r=0.89, p<0.05). CONCLUSION: These findings suggest a possible involvement of neutrophil in the development of bronchoconstiction after the TDI exposure, and IL-8 might contribute to neutrophil recruitment to airway mucosa. Further investigation will be needed to investigate mechanism of neutrophil activation in the pathogenesis af TDI-induced OA.

Eccrine spiradenoma is clinically characterized by a solitary, movable, tender noduie occurring most frequently on the ventral surfase of the upper body. A striking symptom is paroxysmal pain. Histopathologically, the encapsulated lobules of the tumor are composed of masses of basophilic cells, usually arranged in whorls, cords, and pseudogland.s. Within the whorls and pseudoglands, two types of celIs are notedperipheral intensely staining cells and central pale-staining cells. We describe herein a patient with an indolent eccrine spiradenoma, which had been diagnosed histopathologically.

BACKGROUND: There have been few reports suggesting involvement of mast cell and neutrophil to induce bronchoconstriction in aspirin-sensitive asthrna. OBJECTIVE: To evaluate mast cell and neutrophil activation in pathogenesis of aspirin-sensitive asthma. MATERIAL AND METHOD: We observed changes of serum NCA and MPO levels during L-ASA bronchoprovocation test in 14 subjects with aspirin-sensitive asthma. RESULTS: Serum NCA was significantly increased at 30 min(p=0.01) after the inhalation of L-ASA and then, no significant changes were noted at 240 min (p=0.14). NCA was significantly higher in subjects with late asthmatic responses than in those without it (p=0.04). Serum MPO level tended to increase at 30 min with no statistical significance (p=0.08), and then it significantly decreased at 240 min (p=0.05). There was no significant correlation between serum NCA and MPO level (r=0.22, p=0.58). CONCLUSION: These results support the view that NCA derived from mast cell may contribute to neutrophil recruitment into the airway in aspirin-sensitive asthmatic patients.

BACKGROUND: IgE antibodies have been considered to play an important role in the pathogenesis of atapic asthma. However, there have been only few studies on the role of IgE in airway secretion in the pathogenesis of bronchial asthma. This might be partly due to difficulty in sampling of airway seceretion from asthmatic patients. Recently, sputum induction method by inhalation of nebulized hypertonic saline was developed, and proved to be valid and useful method for obtaining airway secretion from asthmatic patients for studying airway inflammation. OBJECTIVE AND METHOD: To evaluate the usefulness of sputum induction method for studying IgE antibodies in airway secretion from atopic asthmatic patients, total IgE levels in induced sputum from 54 atopic asthmatics were measured by enzyme-linked immunosorbent assay(ELISA) and tried to find an association with sputum eosinophilia. RESULT: Total IgE levels in induced sputum were significantly higher in atopic asthmatic patients(1.27+82.066 IU/ml) than in controls(0.203+0.291 IUgmP)(p<0.05). In atopic asthmatic patients, total IgE levels in induced sputum were not significantly different between patients with and without sputum eosinophilia(>5% of 200 counted leukocytes). There was a significant correlation of total IgE levels between induced sputum and serum in atopic asthmatic patients(r=0.60, p<0.05). Total IgE levels in induced sputum(1.278+ 2.066) were significantly higher than saliva sample(0.504 + 1.111 IU/ml) from atopic asthmatic patients(p<0.05). CONCLUSION: These results suggest that total IgE levels are increased in the induced sputum of atopic asthmat,ic patients and sputum induction method is a useful tool for studying IgE antibodies in airway secretion from asthmatic patients.
