Abstract
Hyposensitization therapy gave a subjective improvement in 84% of grass pollen-sensitive patients receiving an 18 dose course of aqueous pollen extract (SDV) and in 69% of patients receiving a 3 dose course of glutaraldehyde-treated pollen-tyrosine adsorbate (Pollinex). Systemic reactions to treatment were considerably more frequent with the aqueous course, but virtually absent with the short adsorbate course, which seems therefore more convenient for the patient. The SDV treatment induced a more pronounced Ig[immunoglobulin]G antibody response in patients and in guinea-pigs receiving the clinical dosage schedule. The Pollinex treatment showed a tendency to enhance the IgE antibody response in new patients.
