In twenty five patients who diagnosed as nasal allergy to house dust mite and treated with immunotherapy, the changes of the symptoms, problems of immunotherapy were investigated by the questionaire, and symptom diary. Skin prick test, eosinophil
and
basophilic cell count in nasal secretion and serum IgE before and after immunotherapy were investigated also.
@ES The results were as follow :
@EN 1) Twenty three patients were satisfied with the immunotherapy and two patients were not. Nasal obstruction was improved mostly and rhinorrhea was improved leastly.
2) The frequency of sneezing, nasal obstruction, frequency of nasal blowing, drug therapy and symptom duration, disability in social working improved significantly by immunotherapy(P<0.001).
3) Three patients complained of the high cost of the immunotherapy, two patients complained of frequent visiting the hospital, however twenty patients had no complaint.
