THERAPEUTICS AND PROCESSES FOR TREATMENT OF IMMUNE DISORDERS

摘要

Processes of diagnosing or treating an autoimmune abnormality are provided whereby the presence of IgA anti-neutrophil cytoplasmic antibodies (ANCA) in a subject are detected correlating with both presence and severity of disease such as Wegener's granulomatosis (WG). The FCAR genotype predicts whether IgA ANCA will be stimulatory or inhibitory of neutrophil activation such that in subjects with an inhibitory genotype, IgA ANCA will act as an inhibitor of disease severity, and in subjects with a proinflammatory genotype, IgA ANCA will increase disease severity as observed by increased prevalence of renal disease in WG. Thus, individualized medical treatment is possible based on determination of the presence of IgA ANCA and FCAR genotype.
