A trial of hyposensitization in 1974/5 in the treatment of hay fever using glutaraldehyde-pollen-tyrosine adsorbate.

One hundred patients with hay fever were treated in 1974/5 with a glutaraldehyde-pollen-tyrosine adsorbate, the response to treatment being assessed at the end of the hay fever season by direct questioning of the patient and examination of a daily record card. Successful results of treatment were recorded in 73% of all patients, results for both years being similar both for patients who had been previously hyposensitized and for those who had not previously received this form of treatment. Side reactions to treatment were generally infrequent or mild, and in only one patient was it necessary to discontinue treatment due to side reactions.
