Participants must not have had prior autoimmune disorders requiring cytotoxic or immunosuppressive therapy, or autoimmune disorders with visceral involvement. Participants with an active autoimmune disorder requiring these therapies are also excluded. The following will not be exclusionary:\r\n* The presence of laboratory evidence of autoimmune disease (e.g. positive antinuclear antibodies [ANA] titer) without symptoms.\r\n* Clinical evidence of vitiligo.\r\n* Hypothyroidism of any etiology on stable thyroid hormone replacement therapy.\r\n* Other forms of depigmenting illness.\r\n* Mild arthritis requiring nonsteroidal antiinflammatory drug (NSAID) medications. Developed autoimmune disorders of Grade 4 while on prior immunotherapy. Subjects who developed autoimmune disorders, of Grade ? 3 may enroll if the disorder has resolved to Grade ?1 and the subject has been off systemic steroids at doses >10 mg/day, for the treatment of the autoimmune disorder, for at least 2 weeks. Active or prior documented autoimmune or inflammatory disorders Patients with autoimmune disorders or history of organ transplantation who require immunosuppressive therapy Uncontrolled autoimmune disorders. Patients with autoimmune disorders under control on medication may be included. Patients with pure red cell aplasia may be included if hemoglobin levels are relatively stable on transfusions or medication History of autoimmune disorders with the exception of vitiligo or autoimmune thyroid disorders Autoimmune disorders on current immunosuppressive therapy Patients must not have a history of, or currently active autoimmune disorders requiring cytotoxic or immunosuppressive therapy, or autoimmune disorders with visceral involvement Any prior autoimmune disorders requiring cytotoxic or immunosuppressive therapy or autoimmune disorders with visceral involvement Patients must not have a history of, or currently active autoimmune disorders requiring cytotoxic or immunosuppressive therapy, or autoimmune disorders with visceral involvement Active/prior autoimmune of inflammatory disorders Autoimmune disorders on current immunosuppressive therapy History of autoimmune disorders requiring cytotoxic or immunosuppressive therapy, or autoimmune disorders with visceral involvement; active or inactive auto-immune disorders (e.g., rheumatoid arthritis, moderate or severe psoriasis, multiple sclerosis, systemic lupus erythematosus, inflammatory bowel disease, etc.) requiring treatment\r\n* The following will not be exclusionary:\r\n** Vitiligo, thyroiditis or eczema requiring systemic steroids at a dose =< 7.5 mg/day of prednisone or equivalent; individual cases can be discussed with the principal investigator Participants must not have had prior autoimmune disorders requiring cytotoxic or immunosuppressive therapy, or autoimmune disorders with visceral involvement; participants must not have an active or inactive autoimmune disorders (e.g., rheumatoid arthritis, moderate or severe psoriasis, multiple sclerosis, inflammatory bowel disease, etc.); participants who are receiving therapy for an autoimmune or inflammatory disease requiring these therapies are also excluded Autoimmune disorders and other diseases that compromise or impair the immune system. No history of autoimmune disorders Known clinically significant autoimmune disorders requiring on-going systemic immune-suppression for control Patients on immunosuppressive therapy or with immune system disorders, including autoimmune disease Subjects with any major autoimmune diseases or autoimmune disorders requiring systemic iv/oral steroids or immunosuppressive or immunomodulatory therapies. Autoimmune disorders confined to the skin (e.g. psoriasis) are eligible, and topical steroids are allowed for the treatment of such skin disorders.
