“…In this series of hay fever patients no statistically significant difference in titer increase could he proved between clinically improved patients and unimproved ones. Other authors, too, have had the same experience (4,14).

“…During immunotherapy of allergic patients antibodies are formed which can be detected by hemagglutination with allergen-coated erythro cytes [17,32,37], by inhibition of the in vitro release of histamine from allergen-challenged leukocytes [23,30] and by binding of radioactivelylabelled antigen [25,43,44,46]. The amount of antibodies formed ap pears to be related to the amount of antigen used for immunotherapy [23,32].…”

The subclasses of IgG antibodies formed by grass pollen-allergic patients during immunotherapy were investigated by using a radioallergosorbent test (RAST) and a quantitative immunofluorescence method known as the defined antigen substrate spheres (DASS) system. By the use of rabbit antisera directed against the subclasses of IgG, the specificity of which was checked in the passive hemagglutination and immunofluorescence techniques, it was shown that a relatively high proportion of the grass pollen-specific antibodies belonged to the IgG4 subclass. Apart from the high binding activity of IgG4 which increased during treatment, a moderate binding activity of the other subclasses was also found. Binding of all subclasses increased slightly in the pollen season and could be specifically blocked by preincubation with soluble grass pollen extract. The results of the IgG4 binding, determined in vitro with the DASS system, and the blocking activity of the sera, determined in vivo by skin tests are suggestive for a relation between these activities. Also in the group of patients with a low IgE-RAST score, the skin reactivity decreased as the IgG4 binding activity increased.
