Is is possible to predict the clinical effect of hyposensitization?
Sera from 73 grass pollen allergic patients in two double blind studies on hyposensitization were investigated for IgE response towards one major timothy allergen-antigen 19 (Ag 19) by means of crossed radioimmunoelectrophoresis (CRIE). The clinical efficacy of hyposensitization after initial preseasonal treatment was positively correlated with increase in specific IgE binding to Ag 19. It was possible to predict the clinical efficacy by comparing CRIE performed on sera before and after 3 months of treatment.
