This study will examine the safety of a new genetically engineered antibody called hLL2 (epratuzumab) in patients with systemic lupus erythematosus (SLE). It will also evaluate whether hLL2 can lessen overall disease activity in SLE or kidney damage in patients with lupus nephritis. Patients 18 years of age and older with mild to moderately active SLE may be eligible for this study. Candidates will be screened with blood and urine tests, a chest X-ray, electrocardiogram (EKG), tuberculin skin test, and screening tests for certain cancers. All participants will receive weekly infusions of hLL2 for 4 weeks. The drug is given through a catheter (small plastic tube) placed through a needle in an arm vein. Each infusion takes about 2 hours, after which the patient is observed in the clinic for 1 to 2 hours before being discharged from the clinic. The first 3 patients in the study will receive the lowest of three different doses used in the study. If this dose is well tolerated, the next 5 patients will receive a higher dose. If the second dose is tolerated, the last 5 patients will be given the highest dose. If any serious problems are encountered at a dose, patients in the next group will receive either the same or lower dose before being advanced to the next level. Patients in the first group will continue taking prednisone at their regular dose. All other patients will have their prednisone tapered gradually, if their condition permits. Patients who have a disease flare may have their prednisone increased for up to 2 weeks, followed by a gradual taper. If the flare is severe or does not respond to the increased prednisone, the patient will be taken off the study and treated to control the disease. Patients will be evaluated at various intervals for up to 8 weeks after the last dose. Several of the screening tests will be repeated throughout the study. No more than 500 ml of blood-the equivalent of a single blood donation-will be collected during a 2-month period. Participants may also be asked to undergo the following optional procedures before starting treatment, 1 week after the last dose and 8 weeks after the last treatment dose: - Bone marrow aspiration - to collect cells from the bone marrow. The hip area is anesthetized and a special needle is used to draw bone marrow from the hipbone. - Tonsil biopsy - The area to be biopsied is numbed with a local anesthetic and small pieces of tissue will be removed with a special type of forceps. (The procedure may be done under general anesthetic.) - Magnetic resonance imaging (MRI) of the abdomen - The patient lies on a table within a metal cylinder (the MRI scanner) for about 30 to 40 minutes while images are obtained with the use of a strong magnetic field and radio waves.
OBJECTIVES: I. Determine the induction of durable remission in patients with life-threatening systemic lupus erythematosus or antiphospholipid antibody syndrome treated with cyclophosphamide. II. Determine the toxicity of this drug in these patients.
OBJECTIVES: I. Determine the safety and long term complications of total body irradiation in combination with cyclophosphamide, anti-thymocyte globulin, and autologous CD34-selected peripheral blood stem cell (PBSC) transplantation in children with refractory autoimmune disorders. II. Determine the efficacy of this treatment regimen in these patients. III. Determine the reconstitution of immunity after autologous CD34-selected PBSC transplantation in these patients. IV. Determine engraftment of autologous CD34-selected PBSC in these patients.
Systemic lupus erythematosus is an often devastating autoimmune disease which affects 1 in 2,000 women in the United States. Recently, several research laboratories have reported that a protein, named CD40-ligand (CD154), is overexpressed by a subset of white blood cells, called lymphocytes, in patients with lupus. Expression of CD154 appears critical to the generation of antibodies that cause disease in lupus. Blocking CD154 interactions in the immune system has been shown to decrease disease activity in animal models of lupus. We propose to study the regulation of CD154 in patients with lupus in hopes of inhibiting its abnormal and deleterious expression.
OBJECTIVES: I. Continue yearly ascertainment visits of all patients of the established Lupus in Minority Populations: Nature vs Nurture (LUMINA) study cohort. II. Recruit into the LUMINA cohort newly diagnosed patients with systemic lupus erythematosus (SLE). III. Determine the impact of additional major histocompatibility complex (MHC) and non-MHC genetic factors not previously examined, specifically tumor necrosis factor, mannose binding protein, interleukin-1 receptor antagonist, and bcl-2, on the course and outcome of SLE. IV. Refine the assessment of those clinical and behavioral-cultural factors found to be important predictors of disease activity, damage, and functioning, thus far in these patients. V. Determine the relationships among disease activity, disease damage, and physical and mental functioning in these patients as the SLE progresses and the factors that predict them.
OBJECTIVES: I. Determine the effect of oral contraceptives containing low-dose synthetic estrogens and progestins on disease activity in premenopausal women with inactive, stable, or moderate systemic lupus erythematosus (SLE). II. Determine the effect of hormone replacement therapy with conjugated estrogens and progestins on disease activity in postmenopausal women with inactive, stable, or moderate SLE.
OBJECTIVES: I. Determine whether there is prompt engraftment after autologous peripheral blood stem cell transplantation using filgrastim (G-CSF) mobilization in patients with life threatening autoimmune diseases. II. Determine the kinetics of T- and B-cell immune reconstitution after a combination of timed plasmapheresis, high dose cyclophosphamide and total lymphoid irradiation, and posttransplant immunosuppression with cyclosporine in these patients. III. Determine whether this treatment regimen beneficially influences the clinical course of these patients.
This study compares the effectiveness of high-dose cyclophosphamide treatment with the "gold standard" treatment, monthly intravenous (IV) cyclophosphamide, in people with moderate to severe lupus that does not respond to high-dose corticosteroid therapy. We will give patients either IV cyclophosphamide (750 milligrams per square meter of body surface area) monthly for 6 months, followed by quarterly maintenance therapy, or high-dose IV cyclophosphamide (50 milligrams per kilogram body weight per day) for the first four days of the study. Patients will be followed for 24 months after therapy.
