Abstract
Half of the patients with ulcerative colitis require at least one course of systemic corticosteroids in their lifetime. Approximately 75% of these patients will also require immunosuppressive drugs (i.e., thiopurines or biological agents) in the mid-term to avoid colectomy. Immunosuppressive drugs raise some concerns due to an increased risk of serious and opportunistic infections and cancer, particularly in elderly and co-morbid patients, underlining the unmet need for safer alternative therapies. Granulocyte/monocytapheresis (GMA), a CE-marked, non-pharmacological procedure for the treatment of ulcerative colitis (among other immune-mediated diseases), remains the only therapy targeting neutrophils, the hallmark of pathology in ulcerative colitis. GMA has proven its efficacy in different clinical scenarios and shows an excellent and unique safety profile. In spite of being a first line therapy in Japan, GMA use is still limited to a small number of centres and countries in Europe. In this article, we aim to give an overview from a European perspective of the mechanism of action, recent clinical data on efficacy and practical aspects for the use of GMA in ulcerative colitis.

Factors associated with the outcomes in ulcerative colitis patients undergoing granulocyte and monocyte adsorptive apheresis as remission induction therapy: A multicenter cohort study. Ther Apher Dial 2020; 25:502-512.

Abstract
Ulcerative colitis (UC) patients harbor activated myeloid leukocytes, which exacerbate and perpetuate UC by releasing inflammatory cytokines. Granulocyte and monocyte adsorptive apheresis (GMA) with an Adacolumn depletes elevated myeloid leukocytes, inducing efficacy with favorable safety. To understand how the clinical outcome with GMA is affected by prior corticosteroid treatment or concomitant immunomodulators, a retrospective multicenter study in 102 UC patients, who had not responded well to first-line medications was undertaken. The remission rates after a course of GMA therapy were significantly higher in corticosteroid-naïve patients compared with those with prior corticosteroid exposure. Absence of corticosteroid background was an independent predictive factor of response to GMA. Further, in corticosteroid-naïve patients, the 1-year cumulative sustained remission rate in patients who did not receive immunomodulators was significantly higher than in patients who received immunomodulators. Accordingly, multivariate analysis revealed that immunomodulator was associated with higher risk of relapse. In conclusion, GMA was an effective treatment for corticosteroid-naïve patients and the efficacy sustained longer in those not receiving immunomodulators during GMA. GMA fulfills the notion that apheresis is to induce disease remission by removing from the body factors known to perpetuate disease. In therapeutic settings, these findings should help better decision making and avoid futile use of medical resources.

Abstract
Ulcerative colitis (UC) still has no definitive cure since its etiology remains unclear. In recent years, considerable progress has been made with regard to our knowledge of the pathogenesis of UC. Advances in biotechnology have led to the development of biologic therapies which selectively target single key mediators or receptors involved in the pathogenesis of the disease - ie, tumor necrosis factor (TNF)-α, integrin, interleukins 12/23. Biologic therapies caused a revolution in the treatment of UC, providing specific options for patients refractory to conventional treatment. In recent years, antibodies anti-TNFα and anti-integrin have shown efficacy in improving the course and prognosis of ambulatory patients with moderate-to-severe UC. Nevertheless, whether biologics have brought so many benefits also for hospitalized patients with acute severe UC is still debated. Acute severe UC is a potentially life-threatening condition that affects up to 25% of patients during the course of their disease. It requires hospital admission due to the risk of complications and death, and it can necessitate urgent colectomy. Major adverse outcomes of acute severe UC are mortality and colectomy. The aim of this systematic review of the literature was to analyze the impact of biologics, in particular infliximab, on the course and prognosis of acute severe UC. Mortality and colectomy rates were considered as outcome measures.

A multicenter retrospective study aiming to identify patients who respond well to adsorptive granulomonocytapheresis in moderately to severely active ulcerative colitis. Clin Transl Gastroenterol 2018; 9:170. [PMID: 29977035 PMCID: PMC6033883 DOI: 10.1038/s41424-018-0037-0] [Citation(s) in RCA: 17] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/11/2018] [Revised: 05/18/2018] [Accepted: 06/08/2018] [Indexed: 02/07/2023] Open
Abstract
Objectives Adsorptive granulomonocytapheresis (GMA) with the Adacolumn has been introduced as a non-pharmacologic treatment for ulcerative colitis (UC). However, a subset of patients who might respond well to GMA needs to be targeted. This study was conducted at three IBD centers to determine factors affecting the efficacy of GMA in patients with moderately-to-severely active UC. Methods From January 2008 to December 2017, a total of 894 active episodes (first attack or relapse) in 593 patients were treated with GMA. Clinical remission was defined as normal stool frequency and no rectal bleeding. Multiple clinical and laboratory parameters at entry were considered for efficacy assessment. Results Clinical remission was achieved during 422 (47%) of the 894 treatment cases. In the multivariate analysis, predictors for favorable response to GMA were age ≤60 years, UC duration <1 year, Mayo endoscopic subscore 2 (vs. 3), steroid naïve UC, and biologic naïve UC. Clinical remission rate was 70% in patients with four of the five factors, 52% in patients with three factors, 46% in patients with two factors, 39% in patients with one factor, and 18% in patients with none of these factors. Overall, the clinical remission rate was significantly higher in patients with a greater number of the five predictors (P < 0.0001). Conclusions GMA appeared to be effective in steroid naïve and biologic naïve patients with short duration of UC. Elderly patients (>60 years) and those with severe endoscopic activity did not respond well to GMA. Additional, well designed, prospective, controlled trials should strengthen our findings.

Abstract
OBJECTIVES Current options for patients with steroid-dependent, chronic-active ulcerative colitis (UC) with insufficient response/intolerance to immunosuppressants (ISs) and/or biologics are limited. The aim of this study was to assess the long-term outcome of granulocyte/monocyte adsorptive (GMA) apheresis (Adacolumn®) in this population. MATERIALS AND METHODS Ninety five adults with steroid-dependent active UC and insufficient response/intolerance to IS and/or TNF inhibitors received 5-8 aphereses in a single induction series of ≤10 weeks. Endpoints included rates of remission (clinical activity index [CAI] ≤ 4) at weeks 24 and 48. RESULTS Of 94 patients (ITT population), remission and response rates were 34.0% and 44.7% at week 24, and 33.0% and 39.4% at week 48. Among 30 patients with prior failure of IS and biologics, 33.3% and 20.0% were in remission at weeks 24 and 48. At both weeks, 19.2% of patients achieved steroid-free remission. Sustained remission or response occurred in 27.7% of patients at 48 weeks. The cumulative colectomy rate at week 96 was 23.4%. Safety was consistent with previous findings. CONCLUSIONS This study confirms findings of the 12-week interim analysis and demonstrates that GMA apheresis provides a safe and beneficial long-term outcome for patients with chronic active UC resistant/intolerant to IS and/or TNF inhibitors.

World J Gastroenterol 2014; 20:17155-17162. [PMID: 25493030 PMCID: PMC4258586 DOI: 10.3748/wjg.v20.i45.17155] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/27/2014] [Revised: 05/17/2014] [Accepted: 06/26/2014] [Indexed: 02/06/2023] Open
Abstract
AIM: To evaluate whether the effectiveness of Granulo-monocyto apheresis (GMA), a technique that consists of the extracorporeal removal of granulocytes and monocytes from the peripheral blood, might vary according to the severity of ulcerative colitis (UC) in patients with mild to moderate-severe disease UC activity.
METHODS: We retrospectively reviewed prospectively collected data of patients undergoing GMA at our inflammatory bowel disease centre who had at least a 6 mo of follow-up. The demographics, clinical and laboratory data were extracted from the patients’ charts and electronic records. The severity of UC was scored according to the Modified Truelove Witts Severity Index (MTWSI). A clinical response was defined as a decrease from baseline of ≥ 2 points or a value of MTWSI ≤ 2 points.
RESULTS: A total of 41 (24 males/17 females; mean age 47 years) patients were included in the study. After GMA cycle completion, 21/28 (75%) of mild UC patients showed a clinical response compared with 7/13 (54%) of patients with moderate to severe disease (P = 0.27). At 6-mo, 14/28 (50%) of the mild UC patients maintained a clinical response compared with 2/13 (15%) of the patients with moderate to severe disease (P = 0.04). After the GMA cycle completion and during the 6-mo follow up period, 13/16 (81%) and 9/16 (56%) of mild UC patients with intolerance, resistance and contraindications to immunosuppressants and/or biologics showed a clinical response compared with 2/6 (33%) and 0/6 (0%) of patients with moderate to severe disease activity with these characteristics (P = 0.05 and P = 0.04, respectively).
CONCLUSION: Patients with mild UC benefit from GMA more than patients with moderate to severe disease in the short-term period. GMA should be considered a valid therapeutic option in cases of contraindications to immunosuppressants, corticosteroids and/or biologics.

Abstract
Granulocyte-monocyte apheresis (GMA) is an emerging therapeutic option in active course of ulcerative colitis (UC). Appropriate GMA dose, including total number, frequency, and duration of the individual GMA session, is a matter of debate. It was the aim of the present study to evaluate the efficacy of a dose-intensified GMA regimen in patients with moderately to severely active UC. A prospective open-label, single-center study was performed in 10 patients with active UC (Rachmilewitz Clinical Activity Index [CAI] ≥ 8 points; Rachmilewitz Endoscopic Index ≥ 7 points). Patients had failed to improve after treatment with steroids and/or immunomodulators. GMA was performed twice weekly for 2 h to a maximum of 10 sessions. In each GMA session, the adsorber was changed after 1 h of treatment time. Four patients achieved remission with a CAI ≤ 4 points. Three patients had a response with an improvement of CAI of ≥3 points. Three patients showed no benefit from GMA. The quality of life score determined by the inflammatory bowel disease questionnaire-Deutschland increased by 26 points in median. First and second filters had similar efficiency in granulocyte and monocyte adsorption. No major adverse effects were observed. Dose-intensified GMA as reported in this study provided an encouraging short-term response rate of 70% in patients with moderately to severely active UC not responding to standard steroid or immunomodulator therapy. Although all patients relapsed not later than 16 weeks, GMA might be useful to reduce steroid and immunomodulator usage, or to delay surgery in this patient group.

Abstract
BACKGROUND Despite the mounting importance of granulocytapheresis (GCAP) for inflammatory bowel disease (IBD) treatment, its effectiveness in steroid-dependent (SD) and steroid-resistant (SR) patients has not been clearly evaluated. This prospective observational study describes the use of GCAP in SD and SR patients with either Ulcerative Colitis (UC) or Crohn's Disease (CD). METHODS 118 patients, 83 affected by UC (55 SD and 28 SR) and 35 by CD (22 SD and 13 SR), were treated with GCAP, using Adacolumn™, for 5 consecutive weeks, 1 session/week. All patients were followed for 12 months after the end of GCAP. Clinical remission was defined as Clinical Activity Index (CAI) ≤6 for UC patients and Crohn's Disease Activity Index (CDAI) <150 for CD patients. RESULTS All patients completed the study; no major complications were reported. At the end of GCAP 71% of UC and 63% of CD patients showed clinical remission. At 6 months the remission was maintained by 66% and 54% of UC and CD patients respectively, while at 12 months the percentages were 48% and 43%, respectively. No differences between SD and SR subgroups were reported at any timepoint. CAI and CDAI values significantly dropped after GCAP treatment and at 6 and 12 months' follow-up (p<0.05 vs baseline for both timepoints). No differences were measured in CAI and CDAI between SD and SR patients. CONCLUSION GCAP therapy is safe and effective in inducing and maintaining clinical remission both in SD and in SR patients affected by either UC or CD.

Abstract
BACKGROUND AND AIM Leukocyte removal therapy (LRT) is recognized as an effective treatment for active ulcerative colitis (UC). In this study, factors associated with the efficacy and long-term effects of LRT were evaluated. METHODS From April 1998 to March 2010, 98 patients with moderate to severe UC were randomly assigned to granulocyte and monocyte/macrophage adsorptive apheresis (GMA) (n = 47) or leukocytapheresis (LCAP) (n = 51) treatment. Patients received two sessions of LRT in the first week, followed by three weekly administrations. All patients were treated with 5-aminosalicylic acid and corticosteroid. Steroid doses were tapered if patients achieved clinical improvement. Clinical remission was defined as a decrease in clinical activity index to < 4 and endoscopic findings to Matts' grade 1 or 2. When clinical activity index decreased but still remained ≥ 5 and Matts' grading was 1 or 2, the patient was considered to have improved. Patients were observed for at least 1 year and diagnosed as relapsed when additional treatment was required. RESULTS Seventy-one (73%) patients achieved clinical remission or improvement. No significant difference was found between LCAP and GMA. Increased age, ≥ 3 attacks of UC, and ≥ 2 sessions of LRT were indicative of refractoriness to LRT. During 1 year observation, 28 patients were relapsed. Duration of UC, ≥ 3 attacks of UC, and ≥ 2 sessions of LRT were indicative of refractoriness to the long-term effects of LRT. CONCLUSION Both GMA and LCAP were effective to treat active UC. However, long duration of UC, multiple UC attacks, and past history of LRT reduce the efficacy.

Abstract
BACKGROUND Several small, prospective, open studies suggest that leukocytapheresis might be efficient in patients with steroid-dependent ulcerative colitis (UC). AIM To evaluate the short- and long-term effectiveness of leukocytapheresis for the management of steroid-dependent UC in clinical practice. METHODS A Web-based, nationwide database specifically designed to record the efficacy and safety data of leukocytapheresis therapy in UC was available from September 2007 in Spain. Clinical data were collected at treatment baseline, 1 month after the last apheresis session (initial efficacy), and 6 and 12 months thereafter (long-term efficacy). Remission was defined as a Mayo Clinic index ≤2 together with complete steroid withdrawal and response as a decrease of ≥3 from the baseline score. RESULTS A total of 142 steroid-dependent UC patients were included in the registry, most of them treated with the Adacolumn™ system. In 69% of patients thiopurine therapy failed to achieve steroid-free clinical remission. Initial clinical remission was obtained in 37% of cases. The initial corticosteroid dose, the number and frequency of apheresis sessions, or the previous failure of thiopurines and/or infliximab did not influence the initial remission rate, but a greater decrease in CRP levels was associated with a higher probability to obtain initial remission. At 6 and 12 months, 41 and 36% of patients were in clinical remission, respectively. Only one serious adverse effect was recorded. CONCLUSIONS In clinical practice, apheresis allows long-term steroid-free clinical remission in up to one third of steroid-dependent UC patients, even in those with prior failure of thiopurines.
