The effect of granulocyte and monocyte adsorptive apheresis on serum cytokine levels in patients with ulcerative colitis.
2013
Abstract Background Granulocyte and monocyte adsorptive apheresis (GMA) with an Adacolumn has been reported to be effective as induction therapy in ulcerative colitis (UC). However, the effects of GMA on serial changes in cytokine levels have not been well characterized. We therefore, investigated cytokine levels in UC patients before and after treatment with GMA. A total of 16 patients with active UC, 10 men, and six women, mean age, 42.6 years were included. Fourteen patients had total colitis and two patients had left-sided colitis. The study included nine patients with a chronic intermittent course, six with a chronic continuous course and one with a single episode. The duration of each GMA session was 60 min at a flow rate of 30 mL/min as per study protocol. Serum levels of 17 cytokines were determined simultaneously using a Bio-Plex suspension array system before and after treatment with GMA. Serum interleukin (IL)-10 and macrophage inflammatory protein-1β levels were increased significantly in UC patients after GMA treatment compared to pre-treatment levels ( P
