Abstract
A method for diagnosing autoimmune disease in mammals, including humans, is described. A blood sample is collected from a subject, and mononuclear white blood cells separated therefrom. The mononuclear cells then are cultured in vitro. Patients with autoimmune disease develop characteristic white cell aggregates with autophagocytosis in the culture. Mononuclear cells from normal patients do not exhibit this cell aggregation with autophagocytosis.
Claims12
A method for diagnosing autoimmune disease in mammals comprising:
- a. isolating a whole blood or bone marrow specimen from a mammalian subject under sterile conditions;
- b. isolating mononuclear cells from the specimen under sterile conditions;
- c. culturing the mononuclear cells in vitro under sterile conditions;
- d. evaluating the cultured mononuclear cells for the presence of autophagocytosis wherein the cultured mononuclear cells are phagocytosing themselves, whereby the presence of autoimmune disease in the mammalian subject is diagnosed.
A method for diagnosing autoimmune disease in humans selected from the group consisting of systemic lupus erythematosus, silicone implant-induced autoimmune reaction, immune deficiency syndrome, hepatitis C, Gulf War Syndrome, multiple chemical sensitivity syndrome, cirrhosis, and Takayasu's arthritis comprising:
- a. isolating a whole blood or bone marrow specimen from a human subject under sterile conditions;
- b. isolating mononuclear cells from the specimen by ficoll-diatrizoate centrifugation under sterile conditions;
- c. culturing the mononuclear cells in vitro in a culture medium comprising RPMI-1640 and 10% fetal bovine serum under sterile conditions;
- d. evaluating the cultured mononuclear cells for the presence of autophagocytosis wherein the cultured mononuclear cells are phatocytosing themselves by light microscopy, whereby the presence of autoimmune disease in the human subject is diagnosed.
