Fig. 1. Clinical course and changes in laboratory findings. With steroid treatment plus plasmapheresis, the patient’s hemoglobin levels and platelet counts recovered rapidly. Renal biopsy was performed during the administration of high-dose steroids. Fig. 2. Light microscopy of the kidney biopsy.

(B) Segmental occlusion of the glomerular capillary lumen and thickening of the shrunken capillary wall with double contours were observed using PAS staining (×400).
