Several new treatments for ulcerative colitis have been developed recently. The depletion of leukocytes by granulocyte and monocyte adsorption apheresis (GMA) was developed and adapted for patients with ulcerative colitis with rare adverse events. We investigated whether treatment with GMA and prednisolone (GMA + PSL) is more effective than PSL alone for patients with moderate to severe ulcerative colitis. Forty-seven patients with moderate to severe ulcerative colitis were retrospectively analyzed. Among the 47 patients, 27 received PSL, while 20 received GMA + PSL. The clinical activity of ulcerative colitis was evaluated using the Lichtiger clinical activity index (CAI) and serum levels of C-reactive protein. Mayo endoscopic score (MES) was used to examine endoscopic activity. The clinical remission rate was significantly higher in the GMA + PSL group than in the PSL group (65% vs 29.6%, p = 0.0206). The mucosal healing rate was also significantly higher in the GMA + PSL group than in the PSL group (60% vs 26%, p = 0.0343). The combination of GMA and steroids may be more effective than steroids alone for inducing clinical remission and mucosal healing in patients with moderate to severe ulcerative colitis.

Background/aims: In chronic inflammatory conditions such as ulcerative colitis (UC), the migration of granulocytes and monocytes/macrophages from the circulation into the colonic mucosa is especially important in maintaining inflammation. The aim of this trial was to assess safety and efficacy of granulocyte and monocyte adsorption apheresis in patients with moderate-to-severe UC refractory to conventional drug therapies. Methods: Twenty-seven patients with moderate (55.6%) to severe (44.4%) active UC refractory to conventional drug therapies who had no changes in their conventional therapy regimen in the past two weeks before the recruitment were enrolled in an open-label trial. Concomitant medications were allowed, and steroids were tapered down according to the clinical activity during the course. We used an adsorptive type extracorporeal column (Adacolumn; JIMRO, Takasaki, Japan), which selectively adsorb granulocytes and monocytes. Patients took five apheresis sessions, each with 60 minutes duration for 5 consecutive weeks. The primary efficacy variables were clinical disease activity, short inflammatory bowel disease questionnaire (SIBDQ), C-reactive protein (CRP), and endoscopic scores. These variables were scored at regular intervals, and analyzed at week 7 on an intention-to-treat (ITT) principles. Results: At 7 weeks, 70.4% of patients showed overall improvement. Clinical disease activity (p < 0.0001), endoscopic score (p < 0.001), and the quality of life as assessed by SIBDQ (p < 0.0001) were significantly improved after the therapy. In 56.3% of concomitant steroid users, tapering down or discontinuation of steroids was possible. Treatment was well tolerated, and no severe adverse events were observed. Conclusions: Adacolumn was very efficacious in patients with moderate-to-severe active UC refractory to conventional drug therapy, but further assessment is needed.
