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. We enrolled 17 elderly ulcerative colitis patients to receive single-needle intensive granulocyte/monocyte adsorptive apheresis, 27 elderly ulcerative colitis patients to receive double-needle intensive granulocyte/monocyte adsorptive apheresis, and 52 nonelderly ulcerative colitis patients to receive single-needle intensive granulocyte/monocyte adsorptive apheresis. Remission and mucosal healing rates after treatment did not differ significantly between elderly ulcerative colitis patients receiving single-needle apheresis and the other two groups. In addition, no serious adverse effects, including blood clots, were observed in single-needle intensive granulocyte/monocyte adsorptive apheresis patients. Single-needle intensive granulocyte/monocyte adsorptive apheresis might be a novel alternative therapeutic option for elderly ulcerative colitis patients before considering corticosteroids.
