title: [Multiple renal infarction associated with lupus anticoagulant in a patient with systemic lupus erythematosus].
abstract: We report a rare case with multiple renal infarction associated with lupus anticoagulant and SLE. A 20-year old woman presented with remitent fever, butterfly rash and, abdominal pain. Laboratory findings showed leukopenia, positive antinuclear and anti-DNA antibodies, and biological false positive for syphilis. Despite a therapy with prednisolone 25 mg/day, the patient showed hypocomplementemia, high titer of anti-DNA antibody and a development of proteinuria and an elevation of serum creatinine. Renal biopsy revealed no abnormalities. She presented abdominal pain with an elevation of serum LDH. Abdominal dynamic computed tomography demonstrated multiple perfusion defects in both kidneys indicating multiple renal infarction. Brain MRI showed multiple micro infarction in the anterior lobes. She was treated with 80 mg of aspirin and have been in remission for two years. Although there have been reported 18 cases with renal infarction associated with antiphospholipid syndrome, this is the first report in Japan. Renal infarction should be differentiated from renal involvement in patients with SLE who have antiphospholipid antibodies.
