Abstract
Some immunological parameters were followed up during the first year of grass pollen desensitization in 15 patients. The skin reactions with grass pollen extract in a series of tenfold dilutions were diminished in all patients during treatment. In nearly all patients a distinct increase in blocking antibody titre was seen. Serum reagin titres as measured by RAST remained constant or decreased somewhat during desensitization. No significant correlations between all three parameters could be demonstrated.
