    Abstract:
    PURPOSE: In Japan, leukocytapheresis has become an accepted therapy for ulcerative colitis. The purpose of this retrospective study was to determine the efficacy of additional leukocytapheresis in patients with moderate-to-severe recurrence of ulcerative colitis. METHODS: From 1998 to 2002, 35 patients with moderate-to-severe recurrence of ulcerative colitis were treated by intravenous prednisolone only or prednisolone plus leukocytapheresis once per week. Previous clinical features of ulcerative colitis, activity index at four weeks, and subsequent course were compared between patients with leukocytapheresis and those without. RESULTS: Sixteen patients were treated with prednisolone only (prednisolone group), and 19 patients were treated with prednisolone plus leukocytapheresis (leukocytapheresis group). Previous prednisolone dose (13.6 +/- 10.4 g vs. 7.9 +/- 9.8 g; P < 0.05) was higher in the leukocytapheresis group than the prednisolone group. Clinical response rate at four weeks was not different between the two groups (leukocytapheresis group, 68.4 percent vs. prednisolone group, 75 percent). However, ulcerative colitis activity index at four weeks was significantly higher in the leukocytapheresis group than the prednisolone group (180.5 +/- 44.2 vs. 142.5 +/- 45.3; P < 0.05). During the subsequent clinical course, 15 of 35 patients required proctocolectomy (leukocytapheresis group, 11 patients vs. prednisolone group, 4 patients). Proctocolectomy rate was significantly different when patients were divided by previous prednisolone dose (P = 0.0029) and ulcerative colitis activity index at four weeks (P = 0.002), but it was not different according to the application of leukocytapheresis. Cox proportional hazards model revealed previous prednisolone dose to be the only independent risk factor for proctocolectomy. CONCLUSIONS: Addition of leukocytapheresis to prednisolone therapy does not seem beneficial in ulcerative colitis patients with moderate-to-severe recurrence.
