[Clinical evaluation of Polish allergen extracts Catalet C and Catalet D in patients with pollinosis]

Abstract

The aim of this paper was to evaluate the clinical efficacy, individual tolerance and side effects of allergen extracts, a weed pollen vaccine Catalet C and a tree pollen vaccine Catalet D. The study was carried out on a group of 41 patients aged from 15 to 46 years in comparison with a placebo group (36 patients). A good tolerance, no serious side effects and a high clinical efficacy, manifested in diminution of pollinosis symptoms in more than 80% of patients was noted. In the treated patients a significant reduction of antiallergic drug consumption in the pollen season was noted as compared with the placebo. The extracts Catalet C and Catalet D are usefull in the specific immunotherapy in weed and tree pollen allergic patients.
