Eligibility Criteria
Ability to provide informed consent to all aspects of the study after full information is provided. Age equal to or older than 18. A diagnosis of Rheumatoid Arthritis (RA) of more than 6 months as defined by the revised American College of Rheumatology criteria. Active RA defined as: 6 or more swollen joints; 6 or more tender joints; ESR greater than 28 mm/hr (or CRP greater than 0.8) or morning stiffness greater than 45 minutes. Incomplete response (defined as persistently active disease as described above) to treatment with at least one of the following regimens for over 3 months: MTX alone (greater than or equal to 17.5 mg/week); MTX (greater than or equal to 17.5 mg/week) plus HCQ (greater than or equal to 200 mg/day); MTX (greater than or equal to 17.5 mg/week) plus SSZ (greater than or equal to 1 gm/d); MTX (greater than or equal to 17.5 mg/week) plus CsA (1-3 mg/kg/day); MTX (greater than or equal to 17.5 mg/week) plus SSZ (greater than 1 gm/day) plus HCQ (greater than or equal to 200 mg/day); No requirement of corticosteroids in doses equivalent to over 10 mg/d prednisone nor other immunosuppressive agents required for the control of extraarticular manifestations at the time of study entry. No active acute or chronic infections requiring antibiotic therapy, serious viral infections (such as hepatitis, herpes zoster, or HIV), or serious fungal infections. Patients with a positive PPD who have not received INH or other antituberculous therapy will be excluded. No pregnant women, nursing mothers, or patients of childbearing age not practicing birth control. No preexisting malignancy other than basal cell carcinoma. No history of stroke, seizure disorder, or chronic neurologic disease. No unstable coronary artery disease, cardiomyopathy, conduction heart block greater than first degree, or a dysrhythmia requiring therapy. No confounding medical illness that in the judgment of the investigators would pose added risk for study participants (e.g., chronic hepatic, renal, or pulmonary disease or bone marrow hypoplasia). No presence of seronegative spondyloarthropathy, systemic lupus erythematosus, systemic sclerosis, inflammatory myopathy, systemic vasculitis, psoriasis, or inflammatory bowel disease. No serum creatinine greater than 2.0 mg/dL on at least 2 different occasions which is sustained for at least 1 month. No hematocrit less than 28% (or hemoglobin less than 9.0 mg/dL), or platelet count less than 100,000, or white blood count less than 3,500/dL. No patients with active lung disease, patients with a chronic and progressive lung disease, or patients with a chronic but stable lung disease with pulmonary function tests of less than 70% of predicted (DLCO less than 60%). No patients with hypogammaglobulinemia (IgG count less than 300). No patients treated with alkylating agents for over 1 year at any time or treated with a purine nucleoside analog at any time.
