Abstract
Leukocytapheresis (LCAP) is reportedly effective for the treatment of active ulcerative colitis (UC) and is a therapeutic option for steroid-dependent or steroid-resistant patients with UC. However, a consensus regarding the use of LCAP for UC patients has not yet been established. Therefore, we analyzed patients' records to identify predictors of response to LCAP therapy and subsequent recurrence. Between October 2001 and March 2011, we recruited 41 patients who had been diagnosed as having UC and had received LCAP therapy. Patients diagnosed with moderate to severe UC with left-side or total colitis and received LCAP therapy for the first time were enrolled. We retrospectively performed a univariate analysis using the patients' medical records to identify factors affecting the therapeutic effect of LCAP. Body mass index exceeding 18.5 kg/m(2) was found to influence the therapeutic effect of LCAP. Male sex was correlated with a rapid response to LCAP treatment and the maintenance of remission. UC patients experiencing their first attack or had an elevated C-reactive protein level prior to LCAP therapy exhibited a relatively long remission period. In the "after LCAP therapy" group, a low Rachmilewitz endoscopic score, low erythrocyte sedimentation rate, or high white blood cell count was associated with a long remission period. Our results suggest that LCAP should be performed for the treatment of early-onset UC. LCAP can be expected to induce a long remission period, enabling mucosal healing, although the factors that affected the remission period did not influence the therapeutic effect and responsiveness.

Abstract
AIM: To identify factors predicting the clinical response of ulcerative colitis patients to granulocyte-monocyte apheresis (GMA).
METHODS: Sixty-nine ulcerative colitis patients (39 F, 30 M) dependent upon/refractory to steroids were treated with GMA. Steroid dependency, clinical activity index (CAI), C reactive protein (CRP) level, erythrocyte sedimentation rate (ESR), values at baseline, use of immunosuppressant, duration of disease, and age and extent of disease were considered for statistical analysis as predictive factors of clinical response. Univariate and multivariate logistic regression models were used.
RESULTS: In the univariate analysis, CAI (P = 0.039) and ESR (P = 0.017) levels at baseline were singled out as predictive of clinical remission. In the multivariate analysis steroid dependency [Odds ratio (OR) = 0.390, 95% Confidence interval (CI): 0.176-0.865, Wald 5.361, P = 0.0160] and low CAI levels at baseline (4 < CAI < 7) (OR = 0.770, 95% CI: 0.425-1.394, Wald 3.747, P = 0.028) proved to be effective as factors predicting clinical response.
CONCLUSION: GMA may be a valid therapeutic option for steroid-dependent ulcerative colitis patients with mild-moderate disease and its clinical efficacy seems to persist for 12 mo.

Abstract
BACKGROUND Leukocytapheresis (LAP) could be an alternative treatment for steroid-dependent ulcerative colitis (UC). AIMS To assess the duration of response at 1 year after this treatment. PATIENTS AND METHODS A prospective study in 18 patients with steroid-dependent UC treated with LAP plus steroids after failure or intolerance to immunomodulators. Clinical and endoscopic (Mayo Clinic index) examinations were performed at 1 month after the last apheresis and at 12 months. The clinical, endoscopic remission and the relapse during the 1-year follow-up were evaluated based on standard parameters. RESULTS Induction of remission: clinical remission: 10/18 (55%). Partial response: 4. Endoscopic remission: 9 (50%), always accompanied by clinical remission. A significant correlation was observed between clinical remission and endoscopic remission (r(s)=0.894; p< or =0.001). At 1 year: sustained steroid-free clinical remission in 9 (50%), all of whom presented initial endoscopic remission. Remission and relapse before 1 year in 17%. A tendency for sustained remission at 1 year was observed when initial endoscopic remission was achieved. CONCLUSIONS Initial remission can be maintained at 1 year in half of the patients without the need for additional steroids. Complete remission and endoscopic mucosal healing is proposed as an objective for achieving a lasting response.

Abstract
The purpose of this meta-analysis was to determine whether selective adsorptive granulocyte and monocyte apheresis (GMA apheresis) using the Adacolumn device can effectively reduce clinical symptoms and endoscopic signs of inflammation in patients with ulcerative colitis (UC). A comprehensive search for randomized controlled trials (RCTs) published up to May 2008 was performed. Each study's quality was evaluated, and the data reported in the results were abstracted. Pooled relative risk (RR) estimates and 95% confidence intervals (CIs) were calculated using the fixed-effects model. Heterogeneity was quantified statistically and explained by the variation in the trial design. Seven RCTs including 594 patients were found, and six RCTs on active UC contributed to the main analyses. In half of the trials, GMA apheresis was compared to steroids. Only one trial was fully blinded. A response or remission after 6 weeks was achieved more often in patients treated with GMA apheresis (RR 1.42; CI 1.15-1.75). Also, after 12 weeks, GMA apheresis produced significantly higher remission rates (RR 1.41; CI 1.08-1.83), but long-term data were sparse. In the trials that compared GMA apheresis and steroids (n = 220 patients), side effects were much less frequent in the GMA apheresis groups (RR 0.19; CI 0.11-0.34). Homogeneous evidence from seven RCTs shows that GMA apheresis induces a clinical remission in a higher proportion of UC patients as compared to conventional medical therapy.

Abstract
OBJECTIVE To evaluate the usefulness of transabdominal ultrasound (US), including contrast-enhanced ultrasonography (CEUS), in predicting the response to cytapheresis therapy in patients with steroid-refractory or -dependent ulcerative colitis (UC). MATERIAL AND METHODS Between January 2005 and June 2008, 26 consecutive patients with steroid-refractory or -dependent UC were treated with granulocyte and monocyte adsorption apheresis (GCAP) or leukocytapheresis (LCAP) at our institute. The clinical activity of UC was evaluated by patients' C-reactive protein (CRP) levels and clinical activity index (CAI) scores. All patients were evaluated by grey-scale US, power Doppler US (PDUS), and CEUS. In CEUS, the color signal patterns were classified as 1 of 2 patterns. In pattern 1, color signals were partially detected in the bowel wall (excluding muscularis propria, the outer thin layer of the bowel wall), whereas in pattern 2, color signals were detected in the entire bowel wall (excluding muscularis propria). Differences between remission or clinical response (group R) and no response (group N) were ascertained for clinical features, clinical activities, and US findings. RESULTS Differences between the two groups were not considered significant for the clinical features, clinical activities, and grey-scale US and PDUS findings. Using CEUS, 4 patients in group R showed pattern 2 (21%), while in group N, all patients showed this pattern, indicating a significant difference between the two groups (p<0.01). CONCLUSION CEUS findings may be helpful in predicting the clinical response to cytapheresis for steroid-refractory or -dependent UC.

Abstract
Intense infiltration of the intestinal mucosa by activated leukocytes is a hallmark of inflammatory bowel disease (IBD). Therefore, removal of circulating leukocytes may be an attractive approach for treating IBD. Leukocytapheresis with Cellsorba, a column of polyethylenephtarate fibers that captures monocytes, granulocytes and lymphocytes, has been used to treat IBD, particularly ulcerative colitis, in Japan and Europe. This article reviews the clinical efficacy and safety data and the mechanisms of action of leukocytapheresis in IBD. Although the majority of clinical studies enrolled only small numbers of patients and had open-labeled designs, leukocytapheresis showed clinical efficacy with an excellent safety profile. Leukocytapheresis depletes granulocytes, monocytes, lymphocytes and platelets, alters cell population profiles, modulates cytokine production, and induces bone marrow-derived cells. In conclusion, leukocytapheresis exerts anti-inflammatory and tissue-repairing effects on the intestinal mucosa in IBD. Further studies are needed to explain the exact mechanism of action and to determine the true efficacy of this approach.

Abstract
Ulcerative colitis is a chronic inflammatory disease that affects the colon and rectum. Its pathogenesis is probably multifactorial including the influx of certain cytokines into the colonic mucosa, causing disease activity and relapse. The hypothesis of removing such cytokines from the circulation by leukocytapheresis was implemented to reduce disease activity, maintain remission, and prevent relapse. Many recent reports not only in Japan, but also in the West, have highlighted its beneficial effects in both adult and pediatric patients. Large placebo-controlled studies are needed to confirm the available data in this regard. In this article, we shed some light on the use of leukocyte apheresis in the management of autoimmune diseases, especially ulcerative colitis.

Abstract
BACKGROUND/AIM The Adacolumn selectively depletes granulocytes and monocytes/macrophages, which are thought to be part of the immunopathogenesis of ulcerative colitis. This work aims at evaluating the safety and clinical efficacy of the Adacolumn in patients with ulcerative colitis in large population-based data sets. METHODS The Adacolumn post marketing surveillance in Japan was undertaken on 697 patients in 53 medical institutions over 7 years from 29 October 1999 to 28 October 2006. Clinical efficacy and safety data were provided by patients' physicians in the participating institutes. RESULTS Safety was evaluated in all the 697 patients and efficacy in 656 patients. At entry, 92% of the patients were on salicylates, 74% on prednisolone and only 9% on immunomodulators. Approximately 40% of patients had severe ulcerative colitis and over 70% had ulcerative colitis that was refractory to conventional medications. There was no serious adverse events; mild to moderate adverse events were seen in 7.7% of the patients. The overall response (remission or significantly improved) was 77.3%; the remission rate based on clinical activity index was 71.1%, while 17.1% remained unchanged and 5.6% worsened. Patients were subgrouped into severe, moderate and mild ulcerative colitis based on clinical activity index (n=578), the response rates were 63.2%, 65.7% and 80.4%, respectively (P<0.001). Endoscopic assessment of efficacy showed very significant mucosal healing, Matts' endoscopic index improved from 3.2+/-0.04 to 2.1+/-0.7 (n=219, P<0.001); reduction in prednisolone dose (P<0.0001); leucocyte count (n=358, P<0.0001) and C-reactive protein (n=314, P<0.0001). Patients who received > or =6 Adacolumn sessions (n=319) did better than patients who received < or =5 sessions (n=188, P=0.004) and multivariate logistic regression analysis revealed that baseline granulocyte count was the strongest predictor of clinical response to Adacolumn (P=0.0191, odds ratio 1.151). CONCLUSION This post marketing surveillance provides the largest ever efficacy and safety data on the Adacolumn therapeutic leucocytapheresis in patients with ulcerative colitis. As a non-pharmacologic treatment for patients with active ulcerative colitis most of whom were refractory to conventional drug therapy, the observed efficacy was very significant. Baseline granulocyte count was convincingly an independent predictor of clinical response.

Abstract
BACKGROUND The aetiology of ulcerative colitis is inadequately understood, and drug therapy has been empirical rather than based on sound understanding of disease aetiology. This has been a major factor for refractoriness and adverse drug effects as additional complications. However, ulcerative colitis by its very nature is exacerbated and perpetuated by inflammatory cytokines, which are released by peripheral granulocytes and monocytes as well. Additionally, active ulcerative colitis is often associated with elevated peripheral granulocytes and monocytes with activation behaviour and are found in vast numbers within the colonic mucosa. Hence, from the clinicopathologic viewpoint, granulocytes and monocytes are appropriate targets for therapy in ulcerative colitis. Based on this thinking, an Adacolumn has been developed for depleting excess granulocytes and monocytes by adsorption. METHODS By colonoscopy, biopsy and histology, we investigated the impact of granulocyte and monocyte adsorption (GMA) on the mucosal level of granulocytes and monocytes in patients with active ulcerative colitis. Forty-five patients (26 steroid naïve and 19 steroid-dependent), mean age 44.7 yr, were included. Twenty patients had total colitis and 25 had left-sided colitis. Each patient was given up to 11 GMA sessions over 12 weeks. No patient received additional medications within 4 weeks (steroid) to 8 weeks (other immunosuppressants) prior to entry or during the GMA course. Colonoscopy together with biopsy was done at entry and within 2 weeks after the last GMA session. RESULTS At entry, the mean clinical activity index was 12.6; range 10-16. A total of 400 colonic biopsies were examined, which revealed massive infiltration of the colonic mucosa by granulocytes, and GMA was associated with striking reduction of granulocytes in the mucosa. At week 12, 33 of 45 patients (73.3%, P<0.01) had achieved clinical remission (the mean clinical activity index <or= 4). Colonoscopy revealed that most non-responders had deep colonic ulcers and extensive loss of the mucosal tissue. The response rate in steroid naïve subgroup was 22 of 26 patients (84.6%, P<0.005) and in steroid-dependent was 11 of 19 (57.9%, P<0.05 and P=0.02154 for steroid naïve vs. steroid-dependent). Patients who achieved remission could continue with their salicylates. On average, remission was sustained for 7.8 months in all 33 responders. CONCLUSIONS This is the first report showing a striking difference in clinical response to GMA between steroid naïve and steroid-dependent patients. Further, patients with deep colonic ulcers together with extensive loss of the mucosal tissue are not like to respond to GMA.

Abstract
BACKGROUND AND AIM Several uncontrolled studies have reported on the efficacy of adsorptive depletion of peripheral blood granulocytes and monocytes/macrophages (GM) in patients with moderate or severe ulcerative colitis. This study was to compare the efficacy and safety of intensive GMA with intensive intravenous prednisolone in patients with severe ulcerative colitis. METHODS Seventy patients with clinical activity index 10-23 were randomly assigned to intensive GMA with the Adacolumn, at 2 sessions/week in the first 3 weeks and then 1 session/week for up to 11 sessions (n = 35) or intravenous prednisolone, 40-60 mg/day for 5-10 days (n = 35). No patient received immunomodulators within 8 weeks prior to entry. Clinical response based on intention to treat was assessed at weeks 2, 6 and 12. RESULTS Four patients in the prednisolone group and two patients in the GMA group discontinued in week 1. At weeks 2, 6 and 12, the remission (clinical activity index < or = 4) rates (%) in the GMA group were 17.1, 54.4, 74.3, respectively. The corresponding values in the prednisolone group were 25.7, 51.4 and 48.6. Further, at week 12, 27 patients (77%) in the GMA group and 5 patients (14%) in the prednisolone group were steroid free (P = 0.0076). In the GMA group, flushing and light-headedness were observed in 5 patients versus typical steroid side effects in 29 patients of the prednisolone group. CONCLUSIONS In this clinical response to GMA was comparable or better than prednisolone. Further, the response to GMA was slower than to intravenous prednisolone, but was more sustainable than the latter.

Abstract
Crohn's disease (CD) and ulcerative colitis (UC) are chronic inflammatory diseases of the gastrointestinal tract. While a cure remains elusive, both can be treated with medications that induce and maintain remission. With the recent advent of therapies that inhibit tumor necrosis factor (TNF) alpha the overlap in medical therapies for UC and CD has become greater. Although 5-ASA agents have been a mainstay in the treatment of both CD and UC, the data for their efficacy in patients with CD, particularly as maintenance therapy, are equivocal. Antibiotics may have a limited role in the treatment of colonic CD. Steroids continue to be the first choice to treat active disease not responsive to other more conservative therapy; non-systemic steroids such as oral and rectal budesonide for ileal and right-sided CD and distal UC respectively are also effective in mild-moderate disease. 6-mercaptopurine (6-MP) and its prodrug azathioprine are steroid-sparing immunomodulators effective in the maintenance of remission of both CD and UC, while methotrexate may be used in both induction and maintenance of CD. Infliximab and adalimumab are anti-TNF agents approved in the US and Europe for the treatment of Crohn's disease, and infliximab is also approved for the treatment of UC.
