ABSTRACT:
The present invention relates to the diagnosis of severe diseases based on the determination of the presence of AGE-IgG autoantibodies in patients and to a method of treatment thereof. More precisely, the invention relates to a method for the diagnosis of severe diseases in patients, which comprises the steps of: a) incubating a solid support coated with an AGE antibody with a biological sample from said patient for a time sufficient for an immunoreaction to occur; and b) determining the presence of AGE-IgG autoantibodies present in said sample; whereby the presence of AGE-IgG autoantibodies in said patient's sample is indicative of a severe disease. Such severe diseases which may be diagnosed in accordance with the present invention include Rheumatoid arthritis, atherosclerosis, amyloidosis, diabetes, Henoch Schonlein Purpura, Crohn's disease and Coeliac disease.
