简要总结
In patients with systemic lupus erythematosus, immunosuppressive therapy to the point of complete immune ablation and hematopoietic stem cell recovery.
详细描述
Systemic lupus erythematosus is a multisystem, inflammatory disorder characterized by the production of antibodies that react with many different self-antigens. Defects in immune regulation underlie the breakdown in self-tolerance.(1) The clinical course of lupus is variable. Aggressive intervention is reserved for disease with characteristic high risk features including diffuse, proliferative glomerulonephritis, pulmonary hemorrhage, cerebritis and other life-threatening manifestations of vasculitis. In patients with SLE and high risk features, we propose extension of current immunosuppressive therapy to the point of complete immune ablation and hematopoietic stem cell recovery.

入选标准
- •Less than age of 60 year at the time of pretransplant evaluation.
- •An established clinical diagnosis of systemic lupus erythematosus with one of the following features:
- •Lupus nephritis-WHO class III or IV (or V when coexistent III or IV) lupus nephritis, failing NIH short course cyclophosphamide therapy (10mg/kg q month for 6 months). Failure will be defined as failure of creatinine to return to normal or pre-exacerbation level.
- •Vasculitis/Immune complex deposition- causing end organ signs or symptoms e.g. cerebritis, transverse myelitis, pulmonary hemorrhage, cardiac failure, renal failure.
- •Cytopenias that are immune-mediated and not controlled by conservative measures including danzole, prednisone, and alkylating agents (cyclophosphamide or vincristine); and any one of the following: transfusion dependant anemia with untransfused hemoglobin less than 8 grams/dl, or platelets less than 40,000/ul without transfusions,or granulocytes less than 1000/ul.
- •Catastrophic Anti-phospholipid Syndrome
- •Ability and willingness to provide informed consent.
排除标准
- •Human immunodeficiency virus (HIV)positive status.
- •History of unstable angina.
- •Uncontrolled diabetes mellitus, or any other illness that in the opinion of the investigators would jeopardize the ability of the patient to tolerate aggressive chemoradiotherapy.
- •Prior history of malignancy except for localized basal cell or squamous skin cancer. Other malignancies for which the patient is judged to be cured by local surgical therapy, such as head and neck cancer, or stage I breast cancer will be considered on an individual basis.
- •Positive serum pregnancy test, inability or unwillingness to pursue effective means of birth control or failure to willingly accept or comprehend irreversible sterility as a side effect of therapy.
- •Psychiatric illness or mental deficiency not due to active lupus cerebritis making compliance with treatment or informed consent impossible.
- •FEV1/FVC<50% of predicted, DLCO <50%of predicted.
- •Resting left ventricular ejection fraction(LVEF)<35% or lupus induced myocarditis.
- •Known hypersensitivity to Escherichia coli.
