Case: A 44-year-old female was admitted to our hospital because of thrombocytopenia and hemolytic anemia. She was diagnosed as SLE twelve years ago and has been treated with immunosuppressive agents, while she experienced a relapse six years ago by lupus nephritis (class III+V). Six months ago she presented with pleurisies and was treated with an increased dose of prednisolone (30 mg/day), which was then gradually tapered to

10 mg/day. The hemoglobin and platelet counts was 6.0 and 200,000/ml, respectively, two weeks before admission, but just after prednisolone was tapered to 8 mg/day, she suddenly presented with thrombocytopenia (16,000/ml), hemolytic selleck chemicals anemia with schistocytes and hematuria/proteinuria with eGFR mildly declined (25.3 ml/min/1.73 m2). The ADAMTS13 activity was below 5% with a positive anti-ADAMTS13 antibody, while the activity of SLE at that time was considered low based

on unremarkable clinical findings and normal titers of serum complement and anti-nuclear autoantibody. She was diagnosed as TTP associated with SLE and steroid pulse therapy by intravenous methylprednisolone was immediately initiated, followed by oral administration Saracatinib of prednisolone (60 mg/day). The platelet count was dramatically improved over 200,000/ml within two weeks and hematuria/proteinuria ameliorated without introduction of plasma exchange. Renal biopsy revealed

mild endothelial Dipeptidyl peptidase cell swelling and the detachment of endothelial cells from the glomerular basement membrane, suggesting the presence of endothelial injury compatible with thrombotic microangiopathy. Discussion and Conclusion: This is a rare case of TTP in a patient with SLE in remission that was successfully treated with glucocorticoid without plasma exchange, suggesting that early immunosuppressive therapy may be useful for patients with TTP secondary to autoimmune disease when renal involvement remains relatively mild.

Renal disease is observed in most patients with SLE at some point in the course of their disease and nearly 50% of all patients with SLE develop renal disease in the first year of diagnosis. Renal biopsy in patients with SLE and any clinical evidence of renal disease is important for diagnosis and further management.
