Single-Needle Intensive Granulocyte and Monocyte Adsorptive Apheresis Is Suitable for Elderly Patients With Active Ulcerative Colitis Taking no Corticosteroids or Biologics.

Twice-weekly intensive granulocyte/monocyte adsorptive apheresis is effective and safe for ulcerative colitis, but maintaining two blood access routes is problematic. We previously reported that intensive granulocyte/monocyte adsorptive apheresis using a single needle in ulcerative colitis is effective and safe. We hypothesized that the efficacy and safety of single-needle intensive granulocyte/monocyte adsorptive apheresis for ulcerative colitis would especially benefit the elderly.
