Systemic lupus erythematosus and thrombotic thrombocytopenic purpura: a case and review

Abstract

Thrombotic thrombocytopenic purpura (TTP) is rare in children with systemic lupus erythematosus (SLE). We report a 15-year-old female who simultaneously presented with TTP and SLE. Kidney biopsy showed membranous nephropathy. Her condition improved with plasmapheresis, intravenous cyclophosphamide, and prednisone pulse therapy. We also reviewed the literature for this association in pediatric patients comparing presenting sequence and renal pathology with cases documented in the adult literature.
