Three cases of childhood-onset male systemic lupus erythematosus (SLE) successfully treated with a combination of pulse methylprednisolone and pulse cyclophosphamide

Abstract

We reported three cases of childhood-onset male systemic lupus erythematosus (SLE), all of whom successfully treated with a combination of pulse methylprednisolone (mPSL) and pulse cyclophosphamide (IVCY). All of them had severe lupus nephritis and were complicated with other collagen diseases. Two cases were complicated with Sjögren syndrome (SS) and the other was complicated with both SS and anti-phospholipid syndrome (APS). After a combination of pulse mPSL and IVCY for a year, followed by oral predonisolone (PSL) and azathioprine (AZA), following up renal biopsy were performed in all cases, which showed histological improvement in glomerulonephritis. One case had flares a year later, but no flares were observed either in clinical symptoms or in laboratory examinations in the others. Their autoantibodies except anti-nuclear antibody (ANA) were eliminated. We suggest a combination of pulse mPSL and IVCY is effective for the patients who are suffering with severe lupus nephritis complicated with the other collagen diseases.
