Endoscopic findings can predict the efficacy of leukocytapheresis for steroid-naive patients with moderately active ulcerative colitis

Figure 1 The patients were divided before LCAP into three groups according to whether their endoscopic findings revealed erosions (A), geographic ulcers (B), or deep ulcers (C). Representative findings are shown.

Figure 2 Change in average CAI score (A) and CRP levels (B) 8 wk after the last LCAP session. The data of the three patients with deep ulcers whose conditions worsened during LCAP are not included. The average CAI dropped from 9.4 ± 1.9 to 3.8 ± 4.8 (P = 0.001) while the average CRP levels before and after LCAP were 1.2 ± 0.8 mg/dL and 1.0 ± 2.0 mg/dL, respectively, and did not differ significantly.
