Compositions, Methods for Treatment, and Diagnoses of Autoimmunity-Related Disorders and Methods for Making Such Compositions

摘要

The present invention provides compositions and methods useful in the diagnosis and treatment of autoimmunity-related disorders, including cancers and other disorders involving angiogenesis, as well as non-cancer disorders involving a dysfunction in the immune system. In some embodiments, the invention described a plasma assay. In other embodiments, urine assay. In certain other embodiments, the invention provides therapeutic methods comprising removing toxic autoantibodies from the circulation of a patient, e.g., via plasmapheresis, and subsequently infusing the patient with one or more immunoglobulins or immunoglobulin complexes to restore the immune system of the patient to a baseline status whereby the patient's restored immune system either eliminates the source of the disorder (e.g., in the case of cancers) or no longer causes the disease or disorder (e.g., in the case of autoimmune disorders such as multiple sclerosis, psoriasis, latent autoimmune type 1 diabetes in adults (LADA) and the like). Methods of making the high activity IVIG preparation are also provided.
