To predict the clinical efficacy of house dust mite immunotherapy (IT), clinical factors before IT were analyzed in relation to clinical efficacy in bronchial asthmatics treated by standard IT method. In 111 asthmatics treated by IT, 88 cases (80%) obtained favorable results over a one-year period, while only 39% of asthmatics without IT showed clinical improvement (p < 0.05, chi 2 test). Factors including severity, skin test threshold, age, age at which IT was started, duration of asthma, onset of asthma, FEV1.0% and serum IgE levels before IT were analyzed. Severity showed the most significant influence on clinical efficacy (r = 0.412, p < 0.01). A study to determine whether some specific criteria could be used to predict the clinical efficacy of IT was then carried out. Using multivariate analysis with the factors above mentioned, the clinical efficacy ranging from deteriorated to good response could be expressed as a formula with a multi-regression coefficient of 0.56, p < 0.05. Moreover, the application of linear discriminating analysis gave an 80% true positive discriminating rate in 75 asthmatics. In both methods, severity seemed to be the most important factor, skin test threshold next and FEV1.0% third. The other factors were not significant. Hopefully, the use of this formula in clinical practice will improve the efficacy of IT, thus providing further therapeutic benefits to bronchial asthmatics.

UI MeSH Term Description Entries
D008297 Male Males
D008925 Mites Any arthropod of the subclass ACARI except the TICKS. They are minute animals related to the spiders, usually having transparent or semitransparent bodies. They may be parasitic on humans and domestic animals, producing various irritations of the skin (MITE INFESTATIONS). Many mite species are important to human and veterinary medicine as both parasite and vector. Mites also infest plants. Acarus,Mite
D003888 Desensitization, Immunologic Immunosuppression by the administration of increasing doses of antigen. Though the exact mechanism is not clear, the therapy results in an increase in serum levels of allergen-specific IMMUNOGLOBULIN G, suppression of specific IgE, and an increase in suppressor T-cell activity.

D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement.

D001249 Asthma A form of bronchial disorder with three distinct components: airway hyper-responsiveness (RESPIRATORY HYPERSENSITIVITY), airway INFLAMMATION, and intermittent AIRWAY OBSTRUCTION. It is characterized by spasmodic contraction of airway smooth muscle, WHEEZING, and dyspnea (DYSPNEA, PAROXYSMAL). Asthma, Bronchial,Bronchial Asthma,Asthmas
D015999 Multivariate Analysis A set of techniques used when variation in several variables are studied simultaneously. In statistics, multivariate analysis is interpreted as any analytic method that allows simultaneous study of two or more dependent variables. Analysis, Multivariate,Multivariate Analyses
