Notes:
Specific antibodies isolated by immunoabsorption on four main insolubilized allergens from Dermatophagoides pteronyssinus (DPT) had the following isotypic distribution: in 16 atopic patients, 52% IgG, 40% IgM, 8% IgA, 0.1% IgE and, in 12 non-atopic individuals, 48% IgG, 46% IgM, 6% IgA, 0.03% IgE. The ratios between geometric means of antibody values in each class (atopic vs non-atopies) were 2.4 for IgG, 2.0 for IgM, 2.8 for IgA and 66.7 for IgE. The amount of anti-DPT antibodies in IgG subclasses (did not follow the usual distribution of total IgG subclasses, i.e., IgG1 〉 lgG2 〉 IgG3 〉 IgG4. In atopies the order was IgG2 〉 IgG1 〉 IgG4 〉 lgG3 and in non-atopies, IgG4 〉 IgGl - IgG2 〉 IgG3 although 6/12 of the latter had no detectable (〈 0.5 μg/ml plasma) IgG4.
