Clinical and Immunologic Effects of Monthly Administration of Intravenous Cyclophosphamide in Severe Systemic Lupus Erythematosus

Abstract
Severe systemic lupus erythematosus affecting the kidney or central nervous system may lead to organ failure or death despite treatment with high doses of corticosteroids. To evaluate the clinical and immunologic effects of intravenous cyclophosphamide in this setting, we treated nine patients with monthly intravenous infusions of cyclophosphamide for six months.
