Drug Therapy in Lupus Nephropathy

Studies have shown that up to 26% of patients with systemic lupus erythematoses nephritis may suffer from membranous lupus nephropathy. The disease is characterized by high levels of protein in the urine and may eventually lead to kidney failure.

This study will evaluate the effectiveness and toxic effects of immunosuppressive drug therapy in patients with membranous lupus nephropathy over a 12 month period. The major goal of this therapy is to decrease protein losses and ultimately prevent kidney failure.

Patients enrolled in the study will undergo a routine history and physical examination. In addition, several diagnostic tests will be conducted including; chest x-ray ECG, blood and urine laboratory tests.

Patients will be divided and grouped according to the severity of their disease as shown by kidney function. Each group will then randomly be subcategorized by different treatment plans. Each treatment plan will made up of immunosuppressive medications including prednisone, cyclophosphamide, cyclosporin A, and combinations of these drugs. Patients will receive the medications as directed by the study.

The study will last 12 months and require patients to be admitted for two to five days before the study begins and once the study is completed. Patients will be followed as outpatients throughout the 12 month study.
