Treatment with two medications that suppress the immune system, rituximab and cyclophosphamide, appears to have cured one woman of an otherwise untreatable case of the blood disease known as thrombotic thrombocytopenic purpura (TTP). The findings support the theory that TTP is an autoimmune disease, and not only provide insight into diagnosis and treatment, but also reveal clues about blood clotting and autoimmune diseases in general.
"In this particular patient who did not respond to standard therapy, immunosuppression seems to have been successful," says Morey A. Blinder, M.D., associate professor of medicine and of pathology and immunology at Washington University School of Medicine in St. Louis. "These results are promising for others suffering from similarly resistant cases of TTP."
Blinder led the study, in conjunction with J. Evan Sadler, M.D, Ph.D., professor of medicine and of biochemistry and molecular biophysics. Their findings appear in the Jan. 21 issue of the journal Annals of Internal Medicine.
