A 72-year-old Japanese woman was admitted to our hospital with rapidly progressive glomerulonephritis associated with anti-glomerular basement membrane antibody. Hemodialysis (HD) therapy was initiated on the day of admission using a biocompatible polysulfone (PS) membrane. Her platelet count (PLT; ×104/μL) decreased gradually from 58.7 (day 1) to 5.8 (day 25). Considering the possibility of dialyzer-related thrombocytopenia (DRT), we measured her PLT count before and after the HD session on day 72, which revealed a dramatic decrease of 7.5 to 4.3. This finding suggested that the PS dialyzer caused PLT depletion. After discontinuation of the PS dialyzer, DRT was resolved.
