A retrospective study to investigate the efficacy and safety of granulocyte and monocyte adsorptive apheresis in patients with primary sclerosing cholangitis with ulcerative colitis. J Clin Apher 2024; 39:e22099. [PMID: 37990778 DOI: 10.1002/jca.22099] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/25/2023] [Revised: 09/24/2023] [Accepted: 11/07/2023] [Indexed: 11/23/2023]
Abstract
BACKGROUND AND AIMS Primary sclerosing cholangitis has a poor prognosis and can be accompanied by ulcerative colitis. Infection control is essential, so immunosuppressive drugs should ideally be preferably. Granulocyte and monocyte adsorptive apheresis does not suppress the immune system and is used to treat ulcerative colitis. Therefore, this study investigated the efficacy and safety of granulocyte and monocyte adsorptive apheresis in patients with primary sclerosing cholangitis and ulcerative colitis. METHODS We retrospectively evaluated data from patients with primary sclerosing cholangitis with ulcerative colitis who visited our hospital from April 2000 to December 2022 and underwent granulocyte and monocyte adsorptive apheresis (n = 10, number of treatment cycles = 15). Study endpoints were remission induction rate and safety, assessed as changes in liver functions and adverse events. RESULTS Seven of the 10 patients were male. The median (min-max) age was 23 (18-77) years. The most common disease type was right-dominant pancolitis. Remission occurred after 86.6% of cycles (13/15). Serum alkaline phosphatase and Aspartate transaminase were significantly lower after treatment (P = .0124, P = .002), and no negative effects on liver function were seen. The only adverse events were headache (n = 1) and decreased blood pressure (n = 1). CONCLUSIONS Granulocyte and monocyte adsorptive apheresis has high efficacy for intestinal lesions and improves alkaline phosphatase and aspartate transaminase levels (high levels are a poor prognosis factor). It appears to be a treatment option in patients with primary sclerosing cholangitis associated with ulcerative colitis.

World J Gastroenterol 2021; 27:1194-1212. [PMID: 33828394 PMCID: PMC8006096 DOI: 10.3748/wjg.v27.i12.1194] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/04/2020] [Revised: 02/11/2021] [Accepted: 03/11/2021] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND It is a crucial issue for patients with refractory ulcerative colitis (UC), including steroid-dependent and steroid-refractory patients, to achieve and maintain steroid-free remission. However, clinical studies focused on the achievement of steroid-free remission in refractory UC patients are insufficient. Cytapheresis (CAP) is a non-pharmacological extracorporeal therapy that is effective for active UC with fewer adverse effects. This study comprised UC patients treated with CAP and suggested the efficacy of CAP for refractory UC patients.
AIM To clarify the efficacy of CAP in achieving steroid-free remission in refractory UC patients.
METHODS We retrospectively reviewed the collected data from 55 patients with refractory UC treated with CAP. We analyzed the following points: (1) Efficacy of the first course of CAP; (2) Efficacy of the second, third, and fourth courses of CAP in patients who experienced relapses during the observation period; (3) Efficacy of CAP in colonic mucosa; and (4) Long-term efficacy of CAP. Clinical efficacy was evaluated using Lichtiger’s clinical activity index or Sutherland index (disease activity index). Mucosal healing was evaluated using Mayo endoscopic subscore. The primary and secondary endpoints were the rate of achievement of steroid-free remission and the rate of sustained steroid-free remission, respectively. Statistical analysis was performed using the paired t-test and chi-squared test.
RESULTS The rates of clinical remission, steroid-free remission, and poor effectiveness after CAP were 69.1%, 45.5%, and 30.9%, respectively. There were no significant differences in rate of steroid-free remission between patients with steroid-dependent and steroid-refractory UC. The mean disease activity index and Lichtiger’s clinical activity index scores were significantly decreased after CAP (P < 0.0001). The rates of steroid-free remission after the second, third, and fourth courses of CAP in patients who achieved steroid-free remission after the first course of CAP were 83.3%, 83.3%, and 60%, respectively. Mucosal healing was observed in all patients who achieved steroid-free remission after the first course of CAP. The rates of sustained steroid-free remission were 68.0%, 60.0%, and 56.0% at 12, 24, and 36 mo after the CAP. Nine patients (36%) had maintained steroid-free remission throughout the observation period.
CONCLUSION Our results suggest that CAP effectively induces and maintains steroid-free remission in refractory UC and re-induces steroid-free remission in patients achieving steroid-free remission after the first course of CAP.

Abstract
BACKGROUND The contemporary management of ambulatory ulcerative colitis (UC) continues to be challenging with ∼20% of children needing a colectomy within childhood years. We thus aimed to standardize daily treatment of pediatric UC and inflammatory bowel diseases (IBD)-unclassified through detailed recommendations and practice points. METHODS These guidelines are a joint effort of the European Crohn's and Colitis Organization (ECCO) and the Paediatric IBD Porto group of European Society of Paediatric Gastroenterology, Hepatology and Nutrition (ESPGHAN). An extensive literature search with subsequent evidence appraisal using robust methodology was performed before 2 face-to-face meetings. All 40 included recommendations and 86 practice points were endorsed by 43 experts in Paediatric IBD with at least an 88% consensus rate. RESULTS These guidelines discuss how to optimize the use of mesalamine (including topical), systemic and locally active steroids, thiopurines and, for more severe disease, biologics. The use of other emerging therapies and the role of surgery are also covered. Algorithms are provided to aid therapeutic decision-making based on clinical assessment and the Paediatric UC Activity Index (PUCAI). Advice on contemporary therapeutic targets incorporating the use of calprotectin and the role of therapeutic drug monitoring are presented, as well as other management considerations around pouchitis, extraintestinal manifestations, nutrition, growth, psychology, and transition. A brief section on disease classification using the PIBD-classes criteria and IBD-unclassified is also part of these guidelines. CONCLUSIONS These guidelines provide a guide to clinicians managing children with UC and IBD-unclassified management to provide modern management strategies while maintaining vigilance around appropriate outcomes and safety issues.

Abstract
BACKGROUND AND AIM The number of elderly patients with ulcerative colitis (UC) is increasing. Several new therapies for UC have improved patient outcomes. Leukocytapheresis (LCAP) is an extracorporeal therapy for UC. However, its efficacy and safety for elderly UC patients has not been reported. METHODS We conducted a post hoc analysis of data from a large, prospective, observational study of LCAP, conducted at 116 medical facilities in Japan between May 2010 and December 2012. Of 847 patients included in this analysis, LCAP was used in 75 (8.9%) elderly patients (≥ 65 years) and 772 (91.1%) non-elderly patients. RESULTS There were no serious adverse events in the elderly, and the rate of adverse events between the non-elderly and elderly was not different. Overall rate of remission was also not different between the two groups. In patients who were not on concomitant treatment with corticosteroids, the rate of remission was significantly higher in the elderly group than in the non-elderly group (90.9% [20/22] vs 64.6% [135/209], P = 0.02). CONCLUSIONS Real-world data demonstrate that the safety and tolerability of LCAP were comparable in the elderly and non-elderly groups, indicating that it is well tolerated by elderly UC patients.

Abstract
Objective This study was performed to confirm the efficacy of long-interval cytapheresis on steroid-dependent ulcerative colitis (UC). Methods To discontinue steroids in patients with steroid-dependent UC, we previously designed a novel regimen of cytapheresis (CAP), which we termed "long-interval cytapheresis (LI-CAP)", in which CAP was performed as one session every two or three weeks and continued during the whole period of tapering steroid dosage. In this study, we performed LI-CAP therapy 20 times (11 male and 9 female; mean age 41.8 years) between April 2010 and April 2015 for 14 patients with steroid-dependent UC. We evaluated the effectiveness of LI-CAP by examining the improvement in Lichtiger's clinical activity index (CAI), the rate of clinical remission, and the rate of steroid discontinuation. We further examined the rate of sustained steroid-free clinical remission at 6 and 12 months after LI-CAP in patients who successfully discontinued steroid-use after LI-CAP. The primary endpoint was the rate of discontinuation of steroids after LI-CAP. Results The mean CAI score before LI-CAP (7.550) significantly decreased to 1.65 after LI-CAP (p<0.0001). The rate of clinical remission after LI-CAP was 80%. The rate of steroid discontinuation after LI-CAP was 60.0%. The mean dose of daily prednisolone was significantly decreased after LI-CAP (2.30 mg) compared with that before therapy (17.30 mg) (p=0.0003). The rate of sustained steroid-free clinical remission after LI-CAP was 66.7% at 6 months and 66.7% at 12 months. Conclusion We confirmed that LI-CAP has therapeutic effects on reducing the dosage and discontinuing steroids in patients with steroid-dependent UC.

Abstract
Patients with inflammatory bowel diseases (IBD) require life-long medications, which even if effective have the potential to cause adverse effects as additional morbidity factors. In pediatric patients, drug therapy has more serious limitations, including impaired physical and mental development. A non-drug therapeutic option is believed to be depletion of elevated and activated granulocytes and monocytes known to release inflammatory cytokines, like the CD14+CD16+ monocyte phenotype known to release tumor necrosis factor-α. Areas covered: Granulomonocyteapheresis (GMA) with an Adacolumn as a treatment option for IBD patients has been applied for the past 15 years. This article reviews the argument that GMA is a relevant and effective non-pharmacologic intervention in pediatric IBD setting. Expert commentary: GMA with an Adacolumn has shown promise in adult, pediatric, and adolescent patients with active IBD. There is evidence of post-GMA immunomodulation in terms of increased regulatory T-cell and B-cell activities. Additionally, patients who respond to GMA may attain a favorable long-term clinical course by avoiding pharmacologicals during an early phase of their active IBD. GMA has a good safety profile, especially in difficult-to-treat and pediatric settings. An additional trial is warranted to assess the efficacy of GMA in the early phase of pediatric IBD to optimize patient selection.

Abstract
BACKGROUND AND AIMS Leukocytapheresis is an extracorporeal therapy for ulcerative colitis. However, no large-scale study on leukocytapheresis has been reported. This large-scale, prospective, observational study aimed to evaluate the treatment outcomes of leukocytapheresis for active ulcerative colitis in clinical practice. METHODS Patients with active ulcerative colitis treated with leukocytapheresis using a Cellsorba E column between May 2010 and December 2012 were enrolled from 116 medical facilities in Japan. RESULTS A total of 847 patients were enrolled, and 623 were available for efficacy analysis. Out of 847 patients, 80.3% of the patients had moderate to severe disease activity, and 67.6% were steroid refractory. As concomitant medications, 5-aminosalicylic acids, corticosteroids, and thiopurines were administered to 94.8%, 63.8%, and 32.8% of the patients, respectively. In addition, infliximab and tacrolimus were concomitantly used in 5.8% and 12.3%, respectively. Intensive leukocytapheresis (≥4 leukocytapheresis sessions within the first 2 weeks) was used in >70% of the patients. Adverse events were seen in 10.3% (87/847), which were severe in only 5 patients (0.6%). Any concomitant medications did not increase the incidence of adverse events. Intensive leukocytapheresis was as safe as the conventional weekly procedure. The overall clinical remission rate was 68.9% (429/623), and the mucosal healing rate was 62.5% (145/232). Clinical remission was achieved more frequently and rapidly in the intensive group than in the weekly group. CONCLUSIONS This large-scale study indicates that leukocytapheresis, including intensive procedure, is a safe and effective therapeutic option for active ulcerative colitis.

Abstract
Ulcerative colitis and Crohn’s disease are the major phenotypes of the idiopathic inflammatory bowel disease (IBD), which afflicts millions of individuals throughout the world with debilitating symptoms, impairing function and quality of life. Current medications are aimed at reducing the symptoms or suppressing exacerbations. However, patients require life-long medications, and this can lead to drug dependency, loss of response together with adverse side effects. Indeed, drug side effects become additional morbidity factor in many patients on long-term medications. Nonetheless, the efficacy of anti-tumour necrosis factors (TNF)-α biologics has validated the role of inflammatory cytokines notably TNF-α in the exacerbation of IBD. However, inflammatory cytokines are released by patients’ own cellular elements including myeloid lineage leucocytes, which in patients with IBD are elevated with activation behaviour and prolonged survival. Accordingly, these leucocytes appear logical targets of therapy and can be depleted by adsorptive granulocyte/monocyte apheresis (GMA) with an Adacolumn. Based on this background, recently GMA has been applied to treat patients with IBD in Japan and in the European Union countries. Efficacy rates have been impressive as well as disappointing. In fact the clinical response to GMA seems to define the patients’ disease course, response to medications, duration of active disease, and severity at entry. The best responders have been first episode cases (up to 100%) followed by steroid naïve and patients with a short duration of active disease prior to GMA. Patients with deep ulcers together with extensive loss of the mucosal tissue and cases with a long duration of IBD refractory to existing medications are not likely to benefit from GMA. It is clinically interesting that patients who respond to GMA have a good long-term disease course by avoiding drugs including corticosteroids in the early stage of their IBD. Additionally, GMA is very much favoured by patients for its good safety profile. GMA in 21st century reminds us of phlebotomy as a major medical practice at the time of Hippocrates. However, in patients with IBD, there is a scope for removing from the body the sources of pro-inflammatory cytokines and achieve disease remission. The bottom line is that by introducing GMA at an early stage following the onset of IBD or before patients develop extensive mucosal damage and become refractory to medications, many patients should respond to GMA and avoid pharmacologics. This should fulfill the desire to treat without drugs.

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
OBJECTIVE This study aimed to assess the efficacy and tolerability of leukocytapheresis (LCAP) and to investigate predictive factors for mucosal healing and a sustained clinical response in steroid-free and steroid-refractory patients with ulcerative colitis (UC). MATERIAL AND METHODS Thirty-one steroid-free or steroid-refractory patients with active UC were enrolled. Five or ten consecutive sessions of LCAP were performed in each patient. The efficacy and tolerability was then evaluated at weeks 3 and 6. Endoscopic examination was performed at week 6 to evaluate the mucosal healing, and the sustained cumulative response rate was evaluated at 12 months. RESULTS At week 6, the mean Mayo clinical activity score had decreased significantly from 8.0 to 4.6 in the steroid-free patients and from 8.3 to 3.9 in the steroid-refractory patients. Rachmilewitz's endoscopic index had also decreased significantly from 9.1 to 6.1 in the steroid-free patients and from 10.0 to 5.7 in the steroid-refractory patients. Forty-seven percent of the steroid-free patients and 33% of the steroid-refractory patients achieved mucosal healing. The peripheral platelet counts had decreased significantly at weeks 3 and 6 in the mucosal healing group, compared with the non-mucosal healing group. The patients with a more than 15% platelet reduction had a significantly higher cumulative response rate, compared with the patients without a platelet reduction (p = 0.015). CONCLUSIONS LCAP is beneficial for the induction of mucosal healing in steroid-free and steroid-refractory patients with UC. The degree of platelet reduction during LCAP might be a predictive marker for mucosal healing and a sustained clinical response.

Abstract
Granulocyte-monocyte apheresis is a relatively new therapy that has been proposed, sometimes with controversial results, for the treatment of inflammatory bowel disease, particularly ulcerative colitis. The aim of the present study was to perform a thorough review of the literature on the application of this type of treatment in ulcerative colitis and discuss the results, in order to provide an opinion on its use which is shared by the involved experts. The review of the literature was performed by searching PubMed with appropriate key words. The results obtained suggest that the major role for this treatment at this moment is for those patients with steroid dependency or with major contraindications to use of steroids. However, promising, albeit very preliminary, results have also been observed in steroid-naïve subjects, and this is of particular interest in consideration of the safety profile of this therapeutic method. As such, the Adacolumn may prove useful in specific subgroups of patients. Future phenotypic, genotypic, and molecular characterization of patients with inflammatory bowel disease might prove useful in defining better those subjects who might benefit most from this treatment modality.

Abstract
Ulcerative colitis and Crohn's disease are the two most prevalent inflammatory bowel diseases. In both cases, the medically refractory and steroid-dependent type presents a therapeutic challenge. To help resolve this problem, a mainly Japanese team developed a new therapeutic option. There are two systems, both of which are able to selectively remove the main mediators of the disease, namely the activated pro-inflammatory cytokine-producing granulocytes and monocytes/macrophages, from the patient's blood circulation (GMA = granulocyte monocyte apheresis). One of the two systems is the Adacolumn( (®) ) (Immunoresearch Laboratories, Takasaki, Japan) consisting of the ADA-monitor and a single-use column, which contains approximately 35,000 cellulose acetate beads. The exact mode of action is not yet sufficiently understood, but however, a modulation of the immune system takes place. As a result, less pro-inflammatory cytokines are released. Furthermore, the production of anti-inflammatory interleukin-1 receptor antagonist is increased, and the apoptosis of granulocytes boosted. The decreased LECAM-1-expression on leukocytes impedes the leukotaxis to the inflamed tissue, and CD10-negative immature granulocytes appear in the peripheral blood. Another effect to be mentioned is the removal of the peripheral dendritic cells and the leachate of regulatory T cells (T-regs). The second system is the Cellsorba( (®) ) FX Filter (Asahi Medical, Tokyo, Japan). The range of efficiency, the indication, and the procedure are very similar to the Adacolumn. Solely the additional removal of lymphocytes can possibly limit the implementation since lymphopenia can increase the risk of autoimmune disease. Both systems provide a low-risk therapy with few adverse reactions. ASFA recommendations for GMA in inflammatory bowel disease are 2B due to the fact that not enough randomized double-blind studies are available to proof the efficacy of this treatment.

Abstract
Acquired Immunodeficiency Syndrome (AIDS) is responsible for millions of deaths worldwide. To date, many drug treatment regimens have been applied to AIDS patients but none has resulted in a successful cure. This is mainly due to the fact that free HIV particles are frequently in mutation, and infected CD4(+) T cells normally reside in the lymphoid tissue where they cannot (so far) be eradicated. We present a stochastic cellular automaton (CA) model to computationally study what could be an alternative treatment, namely Leukapheresis (LCAP), to remove HIV infected leukocytes in the lymphoid tissue. We base our investigations on Monte Carlo computer simulations. Our major objective is to investigate how the number of infected CD4(+) T cells changes in response to LCAP during the short-time (weeks) and long-time (years) scales of HIV/AIDS progression in an infected individual. To achieve our goal, we analyze the time evolution of the CD4(+) T cell population in the lymphoid tissue (i.e., the lymph node) for HIV dynamics in treatment situations with various starting times and frequencies and under a no treatment condition. Our findings suggest that the effectiveness of the treatment depends mainly on the treatment starting time and the frequency of the LCAP. Other factors (e.g., the removal proportion, the treatment duration, and the state of removed cells) that likely influence disease progression are subjects for further investigation.

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
Therapeutic apheresis, a novel approach for immunodisorders, has been used in the last decade for the treatment of ulcerative colitis with promising result, and represents an alternative to conventional pharmacological therapy. Selective apheresis is aimed at reducing the number of circulating lymphocytes, interfering with recruitment and activation of mucosal granulocytes and macrophages, reducing cytokine and chemokine production which are thought to contribute to induction and perpetuation of inflammation. The article briefly reports indications, treatment schedule and clinical results of leukocytapheresis in ulcerative colitis. Available data for the two selective adsorption devices so far approved for clinical use (granulocyte-monocyte apheresis- Adacolumn- and leukocytapheresis-Cellsorba) are partially conflicting, and the number of controlled studies too small to draw definitive conclusions. Nonetheless apheresis definitely appears to be an effective non-conventional tool for the treatment of steroid refractory and steroid dependent UC patients with moderately active disease. The excellent safety profile of the procedure makes this approach attractive, both in adult and in pediatric patients, more so in those refractory to conventional drug therapy, who are presently treated with immunosuppressive and biological therapies.

Abstract
The American Society for Apheresis (ASFA) Apheresis Applications Committee is charged with a review and categorization of indications for therapeutic apheresis. Beginning with the 2007 ASFA Special Issue (fourth edition), the subcommittee has incorporated systematic review and evidence-based approach in the grading and categorization of indications. This Fifth ASFA Special Issue has further improved the process of using evidence-based medicine in the recommendations by refining the category definitions and by adding a grade of recommendation based on widely accepted GRADE system. The concept of a fact sheet was introduced in the Fourth edition and is only slightly modified in this current edition. The fact sheet succinctly summarizes the evidence for the use of therapeutic apheresis. The article consists of 59 fact sheets devoted to each disease entity currently categorized by the ASFA as category I through III. Category IV indications are also listed.

Abstract
While several clinical trials have suggested that leukocytapheresis (LCAP) by filtration can benefit patients with active ulcerative colitis, the mechanisms underlying these benefits are largely unknown. The aim of this study was to address the mechanisms that may underlie the therapeutic effects of LCAP using a dextran sulfate sodium-induced colitis model in rats. Treatment with the active column, but not the sham column, improved disease severity by down-regulating pro-inflammatory events, including the cell-proliferative responses and inflammatory cytokine and reactive oxygen production, as well as by up-regulating protective events, including hepatocyte growth factor production, bone marrow-derived endothelial progenitor cell induction, and colonic blood flow levels, which were mediated predominantly by calcitonin gene-related peptide. The improvement was also associated with the increase of Ki-67 labeling in the colonic epithelium. In conclusion, the LCAP procedure was used in a dextran sulfate sodium-induced colitis model in rats under extracorporeal circulation conditions. This approach down-regulated pro-inflammatory events and up-regulated protective events in association with disease improvement. These data suggest that LCAP is feasible in animals and should shed light on the mechanisms of LCAP in clinical settings.

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
Induction and maintenance of remission, mucosal healing, the avoidance of surgical intervention, and decreasing the likelihood of cancer developing are the primary therapeutic goals in ulcerative colitis (UC). For the traditional therapies, 5-aminosalicylic acid (including mesalamine), corticosteroids, and thiopurines (azathioprine and mercaptopurine), there are major changes evolving in terms of formulation, patterns of use, and appreciation of long-term benefits and toxicities. The calcineurin inhibitors cyclosporin and tacrolimus, and infliximab, have recently defined, well-established roles. Preliminary supportive evidence is emerging in relation to novel antiinflammatory molecules such as curcumin, manipulation of the bacterial flora, enhancement of the mucosal barrier, and direct epithelial restoration. For patients in whom the disease is resistant to standard simple therapies, strategies are required to integrate these developing and new therapies into clinical practice. This review aims to highlight the evidence supporting new patterns of use of existing therapies and new therapies, and to devise therapeutic pathways that incorporate these new treatments. We propose how treatment might be optimized to improve the outcome in patients with mild-to-moderately active UC, chronic active UC, resistant proctitis, and fulminant UC.

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.

Matrilysin [matrix metalloproteinase 7 (MMP7)] is induced by mucosal injury of many tissues. To assess function of this proteinase, we subjected wild-type and Mmp7(-/-) mice to acute colon injury. When matrilysin expression was increasing, 73% of wild-type mice died, whereas only 32% of Mmp7(-/-) mice succumbed. Although re-epithelialization was delayed in Mmp7(-/-) mice, overall injury did not differ markedly between genotypes. We hypothesized that differences in acute inflammation caused increased mortality in wild-type mice. Indeed, whereas overall neutrophil influx into tissue was similar in wild-type and Mmp7(-/-) mice, their location and extent of migration differed between genotypes. Neutrophils were dispersed throughout the mucosa and within the lumen of wild-type mice, but these leukocytes were largely confined to the submucosa in Mmp7(-/-) mice. The levels of neutrophil chemokines, keratinocyte-derived chemokine and MIP-2, increased in the colon tissue of both genotypes, but these factors were detected only in lumenal lavages of wild-type mice. Our findings indicate that matrilysin mediates beneficial and deleterious effects in response to injury. On one hand, it promotes re-epithelialization, but it also controls the transepithelial influx of neutrophils, which if excessive, can lead to tissue damage.

Abstract
BACKGROUND To clarify which types of cells produce interferon-gamma-inducible protein 10 (IP-10) and whether IP-10 is associated with the development of ulcerative colitis (UC), we investigated IP-10 production in UC patients. METHODS Serum IP-10 levels were measured using enzyme-linked immunosorbent assay in 29 patients with active and 21 with inactive UC and in 20 controls. The production of IP-10 by granulocytes and monocytes adsorbed to G-1 beads was examined. In 21 active UC patients treated with granulocyte and monocyte/macrophage adsorptive apheresis (GMA), serum IP-10 levels were measured before and after treatment. IP-10-positive cells in UC mucosa were also examined immunohistochemically using tissues obtained by surgical resection and colonoscopic biopsies. RESULTS Serum IP-10 levels in active UC patients were significantly higher than those in inactive patients, although even in the latter the levels were increased compared with those in controls. IP-10 production by granulocytes and monocytes in active UC patients was significantly higher than that in controls. Furthermore, the number of IP-10-positive cells was elevated in the colonic mucosa of patients with active UC, and one of the main subpopulations of IP-10-positive cells was granulocytes. Serum IP-10 levels decreased following GMA treatment in responders, but not in nonresponders. Interestingly, serum IP-10 levels before GMA were higher in responders than in nonresponders. In parallel with the serum levels, IP-10-positive cells also decreased following GMA treatment. CONCLUSIONS Serum IP-10 levels reflected UC disease activity, and the source of IP-10 was granulocytes and monocytes. Furthermore, serum IP-10 levels may be a marker for the responsiveness of patients to GMA treatment.

Abstract
The etiology of inflammatory bowel disease (IBD) is not completely understood, thus current therapies have been empirical and directed at treating symptoms rather than addressing the cause. In IBD, the overexpression of proinflammatory cytokines, such as tumor necrosis factor-alpha, interleukin-1beta, interleukin-6, leads to a persistent intestinal inflammatory response that damages the intestinal mucosa. Recent advances in pharmacologic therapies that target specific cytokines, chemokines, and adhesion molecules have proved successful in alleviating symptoms for some patients. There are 2 selective adsorption apheresis devices that remove leukocytes from whole blood, which are currently available in Japan and Europe-the Cellsorba leukocytapheresis column and the Adacolumn adsorptive extracorporeal granulocyte/monocyte apheresis device. The purported mechanisms of action of these devices have been extensively reviewed and are believed to exert an immunomodulatory and/or anti-inflammatory effect on patients with systemic inflammatory disease. The clinical trials presented here indicate that selective leukocyte apheresis effectively removes activated granulocytes and monocytes/macrophages from peripheral blood while maintaining an excellent safety profile. Despite these findings, large controlled trials of selective leukocyte apheresis in the treatment of IBD are needed to determine the true efficacy of this approach.

Abstract
OBJECTIVES Corticosteroids are a cornerstone in the treatment of a severe attack of ulcerative colitis (UC). The long-term prognosis in this patient group is not well described. We studied the long-term colectomy and relapse rates in patients given intensive intravenous corticosteroid treatment (IIVT) for acute UC. METHODS A retrospective clinical study of 158 patients with UC treated in 1975-1982 with IIVT. Patients were followed-up to death, colectomy or last visit. RESULTS A total of 11 patients were excluded due to change of diagnosis (N = 10) or lost to follow-up (N = 1). The indication for index IIVT in the remaining 147 patients was a severe attack (N = 61), a moderately severe attack (N = 45), a mild attack (N = 29) or chronic continuous disease (N = 12). The median (range) duration of follow-up was 173 (4-271) months in patients escaping colectomy during the first 3 months. Three months after IIVT, the colectomy rates were 28/61 (46%) in a severe attack, 4/45 (9%) in a moderately severe, and 1/29 (3%) in a mild attack. After 10 yr, the colectomy rates were 39/61 (64%), 22/45 (49%), and 8/29 (28%), respectively. During follow-up, neither colectomy incidence beyond 3 months, time to first relapse nor relapse incidence was influenced by severity of initial attack, except for a lower relapse incidence after a severe attack. CONCLUSIONS In patients escaping colectomy during the first 3 months after IIVT, the future prognosis was similar irrespective of initial disease severity.

Abstract
BACKGROUND Approximately 20% of patients with ulcerative colitis have a chronic active disease often requiring several courses of systemic steroids in order to achieve remission, but followed by relapse of symptoms during steroid tapering or soon after their discontinuation. Although short term control of symptoms can be achieved with steroid treatment, this pattern of drug response, known as steroid-dependency, leads to important complications of the treatment, while a significant proportion of patients requires colectomy. AIM To review the studies currently available specifically evaluating the management of steroid-dependent ulcerative colitis. RESULTS The clinical and biological mechanisms of steroid-dependency are not well understood compared with those determining steroid-refractoriness. Very few evidence-based data are available concerning the management of patients with steroid-dependent ulcerative colitis. The therapeutic role of aminosalicylates, thiopurines, methotrexate, infliximab, leukocyte apheresis and other drugs in the treatment of steroid-dependent ulcerative colitis are evaluated. CONCLUSIONS Outcomes of studies in steroid-refractory patients may not be applicable to steroid-dependency. Trials are needed to define the correct approaches and new strategies to ameliorate the therapy of steroid-dependent ulcerative colitis.

Abstract
The treatment of inflammatory bowel disease (IBD) is undergoing rapid and profound change. Entirely new approaches are being developed that reflect a greater understanding of how to control the inflammatory process. These began with inflixumab therapy for Crohn's disease. Additional tumor necrosis antibodies will soon be employed, and other biological agents are being investigated. Probiotics, helminth ova therapy, alternative and complementary treatments, leukocytophoresis, and bone-marrow and stem-cell transplantation are additional exciting regimens that are being explored. Although some of these approaches provide marked improvement in these parameters, others are unproven or fraught with adverse effects and complications. Still, control of ulcerative colitis and Crohn's is improving with more changes likely to come.

Abstract
BACKGROUND The effectiveness of leukocytapheresis against ulcerative colitis has been reported. However, the efficacy of this therapy for steroid-resistant ulcerative colitis patients has hardly been examined. AIMS The aims of this study are to evaluate the efficacy of leukocytapheresis for steroid-resistant ulcerative colitis patients and to identify clinical factors that predict the efficacy of this therapy for these patients. METHODS Clinical factors of 71 steroid-resistant ulcerative colitis patients who underwent leukocytapheresis analysed. RESULTS Of those analysed, 53 (75%) patients showed an initial response to leukocytapheresis. Among cases with initial response, however, only 19 (27%) patients maintained remission for more than 6 months. Steroid-dependent course (Odds ratio =5.53, 95% confidence interval; 1.24-24.73) and a high C-reactive protein degree (Odds ratio=1.6, confidence interval; 1.09-2.35) were predictors of initial response to leukocytapheresis. Rapid response, which means remission induction within three leukocytapheresis sessions, was the only predictor of maintenance of remission for more than 6 months after successful leukocytapheresis therapy (odds ratio=8.01, confidence interval; 1.08-59.37). CONCLUSIONS Leukocytapheresis was effective for steroid-resistant ulcerative colitis patients. However, relapse was frequently observed within short periods after the initial response to this therapy. Patients without a rapid response should be treated with alternative or additional therapies.

Abstract
The American Society for Apheresis (ASFA) Apheresis Applications Committee is charged with a review and categorization of indications for therapeutic apheresis. This elaborate process had been undertaken every 7 years resulting in three prior publications in 1986, 1993, and 2000 of "The ASFA Special Issues." This article is the integral part of the Fourth ASFA Special Issue. The Fourth ASFA Special Issue is significantly modified in comparison to the previous editions. A new concept of a fact sheet has been introduced. The fact sheet succinctly summarizes the evidence for the use of therapeutic apheresis. A detailed description of the fact sheet is provided. The article consists of 53 fact sheets devoted to each disease entity currently categorized by the ASFA. Categories I, II, and III are defined as previously in the Third Special Issue. However, a few new therapeutic apheresis modalities, not yet approved in the United States or are currently in clinical trials, have been assigned category P (pending) by the ASFA Clinical Categories Subcommittee. The diseases assigned to category IV are discussed in a separate article in this issue.

Abstract
GOALS Two uncontrolled, multicenter feasibility studies evaluated safety and pilot efficacy of selective granulocyte and monocyte adsorption apheresis (GMA) with the Adacolumn Apheresis System for treatment of moderate-to-severe ulcerative colitis (UC) and Crohn disease (CD) patients refractory/intolerant to conventional pharmacologic therapy. BACKGROUND Patients with UC and CD, characterized by elevations in peripheral blood granulocytes, monocytes/macrophages, and proinflammatory mediators, may benefit from reductions in activated granulocytes and monocytes by selective apheresis. METHODS Patients underwent weekly Adacolumn sessions for 5 weeks. Pilot efficacy assessments used disease activity index (DAI) for UC (0-12) or CD activity index (CDAI; 0-600) for CD. RESULTS Eleven of 15 UC patients completed all 5 treatments. Mean DAI scores fell from 8.4+/-1.3 (baseline) to 5.2+/-2.9 (week 7). Five patients had DAI reductions of > or = 3 points at week 7. Fourteen of 15 CD patients completed all 5 treatments. Mean CDAI scores fell from 308.0+/-76.5 (baseline) to 200.6+/-117.4 (week 7). Nine CD patients responded (CDAI reductions > or = 70 points) at week 7. Remission (CDAI score < or = 150 at week 7) was observed in 6 patients. There were no device-related serious adverse effects. CONCLUSIONS Treatment with Adacolumn may be feasible and effective in patients with moderate-to-severe refractory inflammatory bowel disease. Larger sham-controlled studies are ongoing.
