Case 1 involved a 34-year-old woman who had been diagnosed with Crohn’s disease (CD) at 30 years old. After deciding to discontinue CD treatment, she was diagnosed with moderate flare-up of CD based on disease activity and endoscopic findings. Inadequate response was seen 7 days after starting oral prednisolone (PSL) at 30 mg/day, so combination therapy was started with intensive granulocyte and monocyte adsorptive apheresis (GMA) plus upadacitinib (UPA) at 45 mg/day. Twelve weeks after starting this combination therapy, clinical remission and endoscopic and histological improvements of the inflamed mucosa were achieved with no adverse events. Case 2 involved a 26-year-old man who had been diagnosed with CD at 13 years old. He was diagnosed with severe flare-up of CD based on disease activity and endoscopic findings due to loss of response to double doses of infliximab (IFX). Combination therapy was started with intensive GMA plus UPA at 45 mg/day. Twelve weeks after starting this therapy, clinical remission and endoscopic and histological improvements of the inflamed mucosa were achieved with no adverse events. The combination of intensive GMA plus UPA appears to have provided an effective therapeutic option for refractory CD in a patient with a 4-year history of CD and refractoriness to systemic corticosteroids, and in another patient with a 13-year history of CD and loss of response to IFX.

A 41-year-old woman had been diagnosed with generalized pustular psoriasis (GPP) for 4 years. Her symptoms had been stabilized with cyclosporine (2 mg/kg/day). Despite increasing the cyclosporine dosage to 3 mg/kg/day, the skin lesions did not improve and the patient developed a fever.  A CT scan revealed a mass lesion measuring 2.5 cm × 4 cm in the right breast and axillary lymphadenopathy. Based on the CT findings, the patient was suspected of having left breast cancer. To manage GPP, granulocyte and monocyte adsorption (GMA) was initiated to minimize the possible adverse effects on the suspected cancer. During the five courses of GMA, the patient’s body temperature returned to a normal degree and the pustules and erythema gradually improved. However, the erythema on her trunk remained. GMA was selected as the initial treatment because the therapeutic strategy for the breast cancer had not yet been determined. Meanwhile, etretinate, corticosteroids, biologics, and their combination are also strong candidates for acute exacerbated GPP. Subsequently, subcutaneous brodalumab administration was introduced; brodalumab allowed the patient to concurrently undergo chemotherapy for breast cancer. The patient underwent a left breast mastectomy and was diagnosed with right breast cancer with right axillary lymph node metastasis. The patient started hormonal therapy, and tumor markers showed a decreasing trend. However, she gradually developed skin metastases, which grew despite treatment. The patient died of breast cancer 4 years after diagnosis. Brodalumab was continued for 4 years, during which no recurrence of GPP was observed.

In conclusion, due to the rarity of the disease, selecting an appropriate therapy for GPP is often challenging especially considering the management of complications. Further accumulation of the treatment experience would be desirable.

We report the case of a 37-year-old male patient diagnosed with moderate left-sided ulcerative colitis (UC). Initial therapy with 5-aminosalicylic acid (5-ASA) was terminated within days due to exacerbation of symptoms, leading to a diagnosis of 5-ASA intolerance. Although induction of remission was achieved with prednisolone, the patient developed steroid dependency. Treatment with vedolizumab and ustekinumab subsequently failed to achieve clinical or endoscopic improvement. Intensive granulocyte and monocyte apheresis (GMA) was introduced, successfully inducing remission. However, during maintenance therapy with GMA, the patient experienced a relapse. Initiation of golimumab yielded suboptimal results, necessitating a combination therapy involving prednisolone and reintensified intensive GMA. This multimodal approach successfully achieved remission induction and maintenance. This case highlights the potential utility of intensive GMA in combination with golimumab and prednisolone for the management of refractory UC, particularly in patients with 5-ASA intolerance and failure of multiple biologic agents. A brief review of the relevant literature is included.

Psoriasis (PS) and inflammatory bowel disease (IBD) are immune-mediated chronic conditions that share pathophysiological processes, including immune system dysfunction, microbiome dysbiosis, and inflammatory pathways. These pathways result in increased turnover of epithelial cells and compromised barrier function. The assessment of the literature suggests that immunopathogenic mechanisms, such as tumor necrosis factor (TNF)-α signaling and IL-23/IL-17 axis dysregulation, are shared by PS and IBD. Clinical characteristics and diagnostic approaches overlap significantly, and advances in biomarker identification benefit both conditions. Current treatments, namely biologics that target TNF-α, IL-17, and IL-23, show promising results in decreasing inflammation and controlling symptoms. Precision medicine approaches are prioritized in prospective therapeutic procedures to tailor pharmaceuticals based on specific biomarkers, perhaps improving outcomes and minimizing side effects. This study thoroughly examines and evaluates the body of research on PS and IBD. Several papers were examined to compile data on clinical features, diagnosis, therapies, pathophysiology, epidemiology, and potential future therapeutic developments. The selection of articles was based on three methodological qualities: relevance and addition to the knowledge of IBD and PS. The retrieved data were combined to provide a coherent summary of the state of the knowledge and to spot new trends. The overview of the latest studies demonstrates that both PS and IBD share pathophysiological foundations and therapeutic approaches. With a spotlight on particular biomarkers, advances in precision medicine provide a promising path toward enhancing therapeutic effectiveness and minimizing side effects.

in CD Moderate to severe Oral corticosteroids. Consider enteral nutritional therapy. TNF inhibitors are recommended to be considered for steroid-dependent or refractory patients. If pharmacotherapy or nutrition therapy is ineffective or unable to adapt, the combination with granulocyte monocyte apheresis (GMA) can be considered.

Background
The clinical efficacy of granulocyte and monocyte adsorptive apheresis (GMA) with Adacolumn in patients (pts) with inflammatory bowel disease (IBD) has been reported in several clinical trials (CT), with significant clinical remission rates. However, evidence on real-world effectiveness of GMA with Adacolumn in ulcerative colitis (UC) or Crohn’s disease (CD) patients who were underrepresented in CT is still limited.

Methods
GRACE is a multicentric, prospective observational study conducted at 31 centres in Spain. The study included adults (≥18 years) diagnosed with UC or CD who had been scheduled to receive GMA with Adacolumn in clinical practice. The study consisted of a baseline (GMA initiation) and 3 follow-up visits at 4, 24, and 48 weeks after the last GMA session. The primary endpoint is the steroid-free remission rate at 24 weeks. This interim analysis is focused on clinical characterization of patients and their management and outcome 4 weeks after GMA treatment.

Results
A total of 95 evaluable patients were included at data cut-off date (25 Sept 2023) (median age: 54 years; 50% men: 81% outpatients). Overall, 89.4% (n=84) of patients had UC, being moderate-to-severe in 85.5%; 57,8% had pancolitis, and the median Mayo score was 5 (interquartile range [IQR], 3-6). Out of the 10 patients (10.6%) with CD, all had B1, and 3 patients had L1, 4 L2 and 3 L3. Overall, 17% had extraintestinal manifestations. Regarding IBD-related therapy, 52.6% of patients had previously received anti-TNF agents, 37.9% thiopurines, and 17.8% JAK inhibitors. Overall, 85.3% of patients received concomitant treatment with GMA, most commonly 5-ASA (60%), corticosteroids (51,6%), ustekinumab (20%), vedolizumab (17.9%), and anti-TNF therapy (11.6%). A total of 71 patients reached the 4-week visit after receiving a median of 10 (IQR, 8-10) GMA sessions (weekly: 26.3%, biweekly: 36.8%, and weekly/biweekly: 31.6%). At week 4, clinical remission was achieved by 50.7% of patients (UC: 49.2%; CD: 66.7%), being 50% and 53.3% in patients concomitantly treated with ustekinumab and vedolizumab. Steroid-free remission rate was 26.1% (UC: 22.2%; CD: 66.7%) at week 4. Overall, 11,2% of patients experienced AEs related to GMA, most of them being mild (73%) or moderate (22.4%). Most common AEs were headache and asthenia. No SAEs were observed.

Conclusion
Preliminary data at 4 weeks show that Adacolumn is a safe and effective treatment in a cohort of IBD refractory patients with previous failure to multiple therapies including thiopurines, biologics and JAK inhibitors. Half of patients were concomitantly treated with biologics, and their clinical remission rate was similar to the overall population. Long-term results of this study (48 weeks) are required to confirm these findings.

Background
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, mainly with anti-TNF.

Methods
The aim of our study was to evaluate the clinical efficacy and safety of combining GMA after primary non-response (PNR) or loss of response (LOR) to ustekinumab (UST) in patients with UC. A retrospective, multicentric study was performed in 12 IBD Units, including all patients with refractory UC who received combined GMA plus UST. The number of GMA sessions, its frequency, filtered blood volume and time of each session were compiled, along with the clinical data. Efficacy was assessed 1 and 6 months after finishing the GMA by partial Mayo score, CRP and faecal calprotectin. Data regarding UST intensification, need for new immunomodulators/biologics and surgery were also compiled. Descriptive statistics and non-parametric tests were used in the statistical analysis.

Results
Nineteen patients were included (15 UC, 2 Crohn’s disease, 2 unclassified IBD; median age 48 years (IQR, 36-63); 68% male). At baseline, 78% were receiving steroids and 23% immunomodulators. Most patients (89%) had prior exposure to anti-TNF agents and 53% to vedolizumab. Baseline Mayo score was 6.5 (IQR, 5-7), with a median CRP of 9 mg/L (IQR, 4.8-20.8) and faecal calprotectin 1,612 mg/kg (IQR, 873-4,152). GMA was started mostly after PNR in 83%, the median number of GMA sessions was 16 (IQR, 11-27) and 50% of patients started maintenance GMA. Partial Mayo score significantly decreased 6 months after the last GMA session (p=0.019). During follow-up, 27% started a new biologic therapy and 13% required surgery. 64% of patients under steroids at baseline were able to stop them. Adverse events were reported in 5% of patients.

Conclusion
GMA can safely recapture the response to UST in refractory patients after PNR or LOR to this drug.

Objective: Granulocyte-monocyte apheresis (GMA) has shown to be safe and effective in treating ulcerative colitis (UC), also in combination with biologics. The objective of this study is 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.

Patients and methods: Retrospective study including all patients with refractory UC who received GMA plus TOFA. Efficacy was assessed 1 and 6 months after finishing GMA by partial Mayo score, C-reactive protein (CRP) and fecal calprotectin (FC). Descriptive statistics and non-parametric tests were used in the statistical analysis.

Results: Twelve patients were included (median 46 years [IQR, 37-58]; 67% female; 67% E3). Patients were mostly receiving TOFA 10mg bid (75%), and 33% also concomitant steroids at baseline. Median partial Mayo score at baseline was 7 (IQR, 5-7), and it decreased to a median of 2 (IQR, 0-3) and 0 (IQR, 0-3) after 1 and 6 months (p=0.027 and 0.020, respectively), while no differences were found in CRP and FC. Clinical remission was achieved by 6 patients both at 1 (50%) and 6 months (67%). CF values<250mg/kg were achieved by 2 and 4 patients at 1 and 6 months (data available in 5 and 7 patients, respectively). No patient required dose-escalation of TOFA, and one patient was able to de-escalate the drug. No patient required colectomy and all patients under steroids were able to stop them. Conclusion: The combination of GMA and TOFA can be effective in selected cases of UC after PNR or LOR to this drug

Aim: Granulocyte and monocyte apheresis (GMA) is a potential therapeutic option when combined with various drugs for treatment of ulcerative colitis (UC). In this study, we analyze the efficacy and safety of GMA combined with vedolizumab (VDZ) during induction in patients with moderate-severe UC and incomplete response to steroids.

Patients and methods: Single-center retrospective review of patients receiving GMA+VDZ. Data on the disease and previous treatments were collected. Clinical response was classified as no response, response without remission, and remission. Available data on biochemical and endoscopic response were included. Adverse events (AEs) were recorded.

Results: The study population comprised 6 patients with UC who had received GMA+VDZ during induction after failure of an anti-TNF agent. The median number of GMA sessions was 5 (IQR 4-5; 3-10). All the patients received VDZ 300mg iv at 0, 2, and 6 weeks, and 5 (83%) received an additional dose at week 10. During maintenance, all the patients continued VDZ iv every 8 weeks. The median follow-up was 57.6 months (IQR: 39-74). Four of the 6 patients achieved clinical remission after GMA+VDZ and continued in deep remission until the end of follow-up. A median, non-significant decrease of 1378μg/g (IQR: 924-5778μg/g) was observed for calprotectin and 42.2mg/l (IQR: 15.3-113.5) for CRP vs. baseline. No patient underwent colectomy. No treatment-related AEs were observed.

Conclusions: GMA+VDZ during induction can be effective and safe in selected patients with moderate-severe UC and partial response to steroids.

Inflammatory bowel disease (IBD) is a group of chronic, nonspecific intestinal inflammatory disorders characterized by localized and systemic inflammation. The use of biologic agents in the treatment of IBD patients is widespread, and the occurrence of primary non-responsiveness during treatment is also significant. This review briefly summarizes the possible reasons for primary non-responsiveness in IBD patients, as well as predictive markers and current strategies to address it, providing a theoretical reference for early identification and management of IBD patients who do not respond to treatment.

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.
