Efficacy and Safety of Adsorptive Granulocyte and Monocyte Apheresis in Elderly and Pregnant Patients With Ulcerative Colitis.

In patients with active ulcerative colitis (UC), adsorptive granulocyte/monocyte apheresis (GMA) is expected to promote remission. We conducted a retrospective cohort study to evaluate the efficacy and safety of GMA in patients with active UC. Twenty-one UC patients including five pregnant or lactating mothers and four elderly patients (aged >60 years) received up to 10 GMA sessions.
