Background: Selective depletion of myeloid lineage leucocytes by adsorptive granulocyte and monocyte apheresis (GMA) with Adacolumn ^® was introduced as a nonpharmacologic treatment for ulcerative colitis (UC) in 2000. It has been reported that GMA may be effective in combination with immunosuppressive treatment in a subset of patients. Τhe purpose of our study is the evaluation of the effectiveness and safety of GMA as a complementary treatment in patients with refractory ulcerative colitis.

Methods: Prospective data collection of a patient cohort with refractory UC receiving Adacolumn ^® as an adjunct to their medical treatment. The therapeutic protocol has 2 phases: The induction phase entails two sessions per week for at least 3 weeks. The maintenance includes one weekly session for one month, one session every 15 days for one the next month, and monthly sessions thereafter. The patients’ medical treatment was maintained during the sessions. As a failure to GMA was considered the need for colectomy, the switch to a different treatment and inability to discontinue steroids. Response was evaluated after completion of at least 6 sessions of GMA.

Results: Ten patients with refractory UC were offered Adacolumn^® between February 2021 and September 2023. Mean age was 39.6 years (22-61years). All patients had failed at least one biologic treatment and two-thirds two biologics. Their treatment which was maintained during GMA was: tofacitinib 10mg bid for 4 patients, ustekinumab 90mg sc every 8 weeks for 3, vedolizumab 300 mg every 8 weeks for 2, and corticosteroids 16mg for one. The median duration of treatment was 5.1 months (2-13 months), while the median number of sessions was 16 (6-45). Clinical and endoscopic remission was achieved in two cases (20%), after 13 sessions for both (in brackets in the Table) whereas two patients (20%) responded clinically according to partial Mayo score. Treatment failure was documented for 6 patients (60%) after 6-45 sessions. Patient number 4 performed 45 sessions in different hospitals because he was reluctant to be operated. Three underwent colectomy and three discontinued due to non-response. No adverse effects were observed. The initial median of partial Mayo score was 6 (5-9) while at the end of the evaluation was 4.5 (0-9). Table 1 summarizes the results of our study.

Conclusion

1) GMA may be beneficial as an adjunct to biologics in refractory to medical treatment UC patients.

2) Interestingly, all patients on tofacitinib showed a favorable response after the addition of GMA.

This observation may help define a subset of UC patients who may benefit the most.

A 68-year-old man developed immune-related adverse event (irAE) colitis after the initiation of nivolumab and ipilimumab combination therapy for malignant melanoma. We diagnosed the patient with grade 3 irAE colitis and started prednisolone (1 mg/kg/day). Although the symptom improved once, it worsened along with the tapering of prednisolone. Therefore, we started infliximab (IFX). However, symptoms did not improve after two doses of IFX. We discontinued IFX and initiated vedolizumab (VED). Because VED alone did not improve the symptom, we started granulocyte-monocyte apheresis (GMA). Twelve weeks after the onset, the colitis was in remission. Therefore, in addition to vedolizumab, GMA may be considered in cases refractory to treatment.

Introduction: Granulocyte–monocyte apheresis (GMA) selectively removes activated leukocytes and immune mediators, and it has shown to be safe and effective in treating ulcerative colitis (UC). Previous reports
have also described its combination with biologics.
Aims & Methods: The aim of our study was to evaluate the efficacy and safety of combining GMA after primary non-response (PNR) or loss of response (LOR) to tofacitinib (TOFA) in patients with UC. A retrospective, multicentre study was performed in 7 IBD Units, including all patients with refractory UC who received combined plus GMA and TOFA. The number of GMA sessions, its frequency, filtered blood volume and length of each
session were compiled, along with the clinical data. Efficacy was assessed 1 and 6 months after finishing GMA by partial Mayo score, CRP and faecal calprotectin. Data regarding TOFA intensification, need for new immunomodulators/biologics and colectomy were also compiled. Descriptive statistics and non-parametric tests were used in the statistical analysis.

Results: Twelve patients with UC were included (median 46 years [IQR, 37-58]; 67% female; 67% E3; 75% non-smokers). Patients were receiving TOFA10 mg bid (75%), 5 mg bid (16%), or 15 mg bid (8%), with 33% receiving
steroids at baseline. All patients had prior exposure to anti-TNF agents, 42% to vedolizumab and 8% ustekinumab. Median baseline Mayo score was 7 (IQR, 5-7), median CRP of 11 mg/L (IQR, 5-32) and faecal calprotectin 800 mg/kg (IQ, 715-2,094). GMA was started mostly after PNR (73%), and the median number of GMA sessions was 11 (IQR, 3-20) and 50% received maintenance GMA. Partial Mayo score significantly decreased 1 month after the last GMA session (p=0.027). Four patients (36%) were switched to a new therapy and no patient required colectomy during follow-up. All patients under steroids at baseline were able to stop them. No patient reported adverse events related to the combination therapy.

Conclusion: Combination of GMA with TOFA can be an effective and safe therapy in selected cases of UC after PNR or LOR to this drug.

Background and Aim: A monotherapy with intensive GMA, biologics or a JAK inhibitor are limited in patients with intractable Crohn’s disease (CD) or ulcerative colitis (UC). We retrospectively evaluated the 10- and 52-week efficacy and safety of combination therapy of intensive GMA with biologics or a JAK inhibitor for intractable UC or CD.
Method: A combination of intensive GMA (2 sessions a week, total 10 times) with tofacitinib (TOF) for active UC was performed and that of intensive GMA with ustekinumab (UST) for active CD was done. Results: Of 6 consecutive UC patients receiving a combination therapy of TOF (20 mg daily for 8 weeks as induction therapy and subsequently 10 mg daily) plus intensive GMA for moderately-to-severely active UC and loss of response to corticosteroids, azathioprine, and/ or biologic therapies, 67% (4 cases) displayed clinical remission according to Mayo score and 100% displayed mucosal healing at 10 weeks. A temporary increase in CPK were seen. Of 5 consecutive CD patients receiving a combination therapy of ustekinumab (every 8 weeks) plus intensive GMA for moderately-to-severely active CD and loss of response to corticosteroids, azathioprine, and/or biologic therapies, 75% displayed cumulative steroid-free clinical remission at 10 weeks and did such remission over 52 weeks under subsequent maintenance monotherapy of UST. The mean CDAI at baseline were 257. Its values at 10 and 52 weeks after the combination therapy with UST plus intensive GMA were 48 and 68, respectively. One case showed mucosal healing at 52 weeks according to SES-CD. No adverse events were observed. Conclusions: Combination therapy of intensive GMA with biologics or a JAK inhibitor appeared to be effective and safe for refractory UC or CD.

Premchand P, Ford L, Venkama DPWE-236 White cell aphaeresis (WCA) with adacolumn is effective in selected cases of chronic refractory colitis with high histological activityGut 2012;61:A394.

Introduction Treatment options for patients with chronic refractory colitis are limited. White cell aphaeresis (WCA) is effective in inducing clinical remission in chronic refractory colitis in patients with a strong inflammatory burden at baseline and histologically active disease. Previous multinational sham controlled trials have demonstrated significant improvement when patients with high histological activity (modified Rileys score) are selected for treatment. Methods A prospective study was conducted in 30 patients with severe steroid -dependent or steroid -refractory ulcerative colitis referred for WCA. Inclusion criteria were (i) High disease activity score (partial Mayo score ≥6) (ii) Intractable symptoms despite treatment with steroids and/or immunosuppressants (iii) Severe disease at endoscopy and histologically. The aim was to induce clinical and IBD-Q remission at 12 weeks. A Mayo score ≤3 defined clinical remission. The 32 item Inflammatory Bowel Disease questionnaire (IBD-Q) was used to assess quality of life prior to treatment and at 12 weeks. Results Patient Characteristics: Prior to treatment 28 patients (93.3%) were prescribed 5-ASA compounds. 12 patients (40%) were prescribed topical therapies (5-ASA enemas or suppositories/steroids enemas). 27 patients (90%) were steroid dependent (Prednisolone mean dose 21.1 mg, median 20 mg). Three patients (10%) were steroid refractory (no response to high dose oral steroids). 13 patients (43.3%) were prescribed Azathioprine of the remainder all had documented intolerance or a contraindication. One patient (3.3%) was prescribed six Mercaptopurine. Five patients had failed Infliximab (16.6%) and in one patient (3.3%) it was contraindicated. 1 patient (3.3%) had failed intramuscular Methotrexate. Outcomes: At week 12 clinical remission (Mayo score ≤3) was achieved in 22 patients (73.3%), 18 patients (60%) were no longer prescribed oral steroids. IBD-Q remission at week 12 was achieved in 19 patients (63.3%). Of the remainder, five patients (16.6%) achieved an IBD-Q response. Of eight patients (26.6%) who failed to achieve clinical remission at 12 weeks, one achieved delayed remission at 20 weeks. Of the remaining seven treatment failures, five underwent colectomy (16.6%). Conclusion WCA can be effective in inducing clinical remission and improving quality of life (IBD-Q) indices in chronic severe steroid refractory ulcerative colitis with highly active disease histologically. This data series suggests WCA should be considered before colectomy in this challenging patient group

To our knowledge, no cases of combined therapy with infliximab and granulocyte apheresis have been previously reported. Our results suggest that this combined therapy is a possible alternative to treat CD patients in the event of loss of response to infliximab.

Refractory ulcerative colitis that fails conventional intense medical treatment often leads to colectomy. Although ciclosporin and infliximab may avert colectomy in certain cases, these treatments come with substantial toxicity and may only act as a bridge to avert emergency surgery. Granulocyte monocyte/macrophage adsorption apheresis is a new treatment and has shown efficacy for refractory colitis in up to 80% of cases in a Japanese study and is apparently only associated with negligible side effects. We report a case of severe refractory proctitis destined for colectomy effectively treated with granulocyte monocyte/macrophage adsorption apheresis. After two of five sessions the patient achieved full clinical remission, which has been sustained with the addition of azathioprine for more than 1 year.

Apheresis has been recognized both economically and therapeutically as a novel approach for the treatment of inflammatory diseases, and certain others, which respond poorly to drug therapy. This report is about Adacolumn, an adsorptive carrier based granulocyte and monocyte apheresis device with a volume of 335 mL, filled with about 220 g of cellulose acetate beads of 2 mm diameter as the column adsorptive carriers. Pre- and post-column leukocyte counts have shown that the carriers adsorb about 65% of granulocytes, 55% of monocytes and 2% of lymphocytes from the blood in the column. Additionally, after apheresis, there is a marked decrease in inflammatory cytokines (TNF-alpha, IL-1beta, IL-6 and IL-8) produced by blood leukocytes, together with down-modulation of L-selectin and the chemokine receptor CXCR3. Adacolumn has been used to treat patients with rheumatoid arthritis, ulcerative colitis and HIV infection. Typical apheresis sessions have been 4-10, at a frequency of one or two sessions per week. Treatment of patients with Adacolumn has been associated with very promising efficacy and safety data. Accordingly, in Japan, Adacolumn has been approved by the Ministry of Health for the treatment of ulcerative colitia. Furthermore, Adacolumn met the required quality and safety standards for medical devices and received an EC certification (CE-mark) from TUV in 1999. However, although Adacolumn carriers are very efficient in depleting excess and activated granulocytes and monocytes/macrophages, the clinical efficacy associated with Adacolumn apheresis cannot be fully explained on the basis of reducing granulocytes and monocytes per se. Hence, a long lasting effect on inflammatory cytokine generation, chemokine activities or immunomodulation is likely, but the precise mechanisms involved are not fully understood yet.
