Clinical evaluation of hyposensitization in allergic rhinitis: comparison of the results obtained with three different extracts. Material from a 3-year study

Abstract

Three different immunotherapy regimens were given during 4 years to 60 randomized patients. One can conclude from the symptom and medication scores that a tyrosine-bound mixture is less active. The results obtained with mixed grass and with highly purified timothy pollen are comparable, but in favour of the latter.
