DETECTION OF AUTOANTIBODIES TO CYTOKERATIN 18 PROTEIN IN PATIENTS WITH BRONCHIAL ASTHMA AND CHRONIC RHINITIS, AND ITS APPLICATIONS INCLUDING A KIT FOR DIAGNOSING BRONCHIAL ASTHMA AND CHRONIC RHINITIS COMPRISING MAMMALIAN CYTOKERATIN 18 PROTEIN

摘要

The present invention is based on the surprising discovery of autoantibodies to cytokeratin 18 protein in the serum samples of patients with bronchial asthma and chronic rhinitis, especially in nonallergic patients. The present invention includes diagnostic methods and a diagnostic kit to detect patients with bronchial asthma and chronic rhinitis associated with autoantibodies to cytokeratin 18. The invention also includes methods and kits to prescribe or monitor treatment for patients with bronchial asthma and chronic rhinitis by detecting autoantibodies to cytokeratin 18. The present invention also includes a pharmaceutical formulation comprising cytokeratin 18 protein to protect patients with bronchial asthma and chronic rhinitis associated with autoantibodies to cytokeratin 18. The present invention also includes methods to treat patients with bronchial asthma and chronic rhinitis associated with autoantibodies to cytokeratin 18 using compounds that inhibit the interaction between such autoantibodies and cytokeratin 18 protein.
