Randomized Controlled Trial Multicenter Study Clinical TrialPAT--the Preventive Allergy Treatment Study design and preliminary results.
The Preventive Allergy Treatment Study, the PAT Study, is a European multi-center study. The end-point is to show in what capacity allergen specific subcutaneous immunotherapy can reduce the outcome of asthma in children with allergic rhinoconjunctivitis sensitized to birch and/or timothy pollen. Two hundred and ten children aged from 5 to 13 years were included in the study. ⋯ Preliminary data show that immunotherapy has been effective, it has been safe and statistically significantly less children in the actively treated group had asthmatic symptoms than children in the control group. Data have not been evaluated from all centers at the moment. The study is a prospective follow-up study, the patients' data will be evaluated next time in the year 2002.
