40Intravenous cyclophosphamide is considered to be the standard of care for treatment of proliferative lupus nephritis. However, its use is limited by potentially severe toxic effects. Cyclosporine A has been suggested to be an efficient and safe treatment alternative to cyclophosphamide. In a randomized, multicenter, open-label, controlled trial the investigators sought to compare the efficacy of oral cyclosporine A with intravenous pulse cyclophosphamide to induce durable remission in patients with lupus nephritis III-IV.
Lupus nephritis occurs in 30-40% of adults with systemic lupus erythematosus and is associated with increased morbidity and mortality. Focal and diffuse proliferative forms of lupus nephritis are known to progress to chronic renal failure unless treated by immunosuppressive drugs. Cyclophosphamide and glucocorticoids are considered to be the standard of care for patients with proliferative lupus nephritis. However, cyclophosphamide may cause a number of toxic effects, such as bone marrow suppression, premature gonadal failure, hemorrhagic cystitis, opportunistic infections, and malignant disease. Hence, efforts are being made to find alternative therapeutic approaches. Cyclosporine is a potent immunosuppressive agent with a more selective mode of action through its unique effect on T cell mediated responses, and is widely used to treat a spectrum of autoimmune and glomerular diseases. Several retrospective series and one randomized trial provided evidence that Cyclosporine A could represent an efficient and safe therapy for proliferative lupus nephritis. In a randomized, multicenter, open-label, controlled trial we compared the efficacy of oral cyclosporine A with intravenous pulse cyclophosphamide to induce durable remission in patients with proliferative lupus nephritis.
Cyclosporine arm (CyA group) consisted of oral cyclosporine A (CyA) 4-5mg/kg/day (given in two divided doses) for 9 months followed by gradually decreasing dose of cyclosporine (3.75-1.25 mg/kg/day) within the next 9 months. The dosage of concomitant glucocorticoids was driven and tapered according to a single treatment protocol.
Cyclophosphamide (CPH) therapeutic arm (CPH group) consisted of 8 boluses of intravenous cyclophosphamide (10mg/kg) given within 9 months in subsequently prolonged intervals (2x3weeks, 4x4 weeks, 2x6 weeks) followed by 4-5 oral cyclophosphamide boluses (10mg/d in 6-8 week intervals). The dosage of concomitant glucocorticoids was driven and tapered according to a single treatment protocol.

Inclusion Criteria: the diagnosis of systemic lupus erythematosus (by meeting 4 criteria of the American College of Rheumatology) renal biopsy documenting lupus nephritis according to the classification of the World Health Organization (WHO) or the updated International Society of Nephrology/Renal Pathology Society (ISN/RPS) as proliferative glomerulonephritis class III (focal) or IV (diffuse) clinical activity as defined by presence of at least two of the following: abnormal proteinuria (more than 500mg of protein in in a 24-hour urine specimen) abnormal microscopic hematuria, or C3 hypocomplementemia (the latter two were defined according to the norms in the laboratories of the participating centers) Exclusion Criteria: treatment with cyclophosphamide or cyclosporine A ever before treatment with other immunosuppressive drugs (such as azathioprine or mycophenolate mofetil) or high dose glucocorticoids (≥ 80mg of prednisone or methylprednisolone) within the last 3 months persistent elevation of serum creatinine (≥140 μmol/l) pregnancy or lactation bone marrow insufficiency with cytopenias not attributable to SLE, and 8severe coexisting conditions, such as infection, liver disease, active peptic ulcer etc.
