A 17-year-old man with ulcerative colitis (UC) presented to our hospital with neck pain and fever after vomiting. On examination, a snowflake sensation was noted in the neck. A chest radiograph showed extensive subcutaneous emphysema in the chest. CT scans showed extensive subcutaneous emphysema in the neck, shoulders and axilla, as well as pneumomediastinum and pneumothorax. A diagnosis of pneumomediastinum with exacerbation of UC was made, and he was fasted and treated with antibiotics. Intensive granulocyte and monocyte adsorption apheresis (GMA) was started for exacerbation of UC. His symptoms and the radiological findings of pneumomediastinum improved. He remained in remission on azathioprine. UC is a chronic inflammatory bowel disease (IBD) associated with extraintestinal manifestations (EIM). Very few cases have been complicated by pneumomediastinum. The increase in alveolar pressure due to vomiting and systemic inflammation-related pleural or esophageal damage may cause pneumomediastinum in this case. Prevention of progression to mediastinitis and treatment of exacerbated UC are contradictory. GMA was successful because it was not an immunosuppressive therapy. Our case highlights that rare EIM may complicate exacerbation of UC.

Inflammatory bowel disease (IBD) is characterized by very severe intestinal inflammation associated with extra-intestinal manifestations. One of the most critical ones is bone destruction, which remains a major cause of morbidity and a risk factor for osteopenia and osteoporosis in IBD patients. In various mouse models of IBD, we and other have demonstrated concomitant bone loss due to a significant increase in osteoclast activity. Besides bone resorption, osteoclasts are known to control hematopoietic niches in vivo and modulate inflammatory responses in vitro, suggesting they may participate in chronic inflammation in vivo. Here, using different models of colitis, we showed that osteoclast inhibition significantly reduced disease severity and that induction of osteoclast differentiation by RANKL contributed to disease worsening. Our results demonstrate a direct link between osteoclast activity and myeloid cell accumulation in the intestine during colitis. RNAseq analysis of osteoclasts from colitic mice revealed overexpression of genes involved in the remodeling of hematopoietic stem cell niches. We also demonstrated that osteoclasts induced hematopoietic progenitor proliferation accompanied by a myeloid skewing in the early phases of colitis, which was confirmed in a model of RANKL-induced osteoclastogenesis. Mechanistically, inhibition of TNF-α reduced the induction of myeloid skewing by OCL both in vitro and in vivo. Lastly, we observed that osteoclastic activity and the proportion of myeloid cells in the blood are positively correlated in patients with Crohn’s disease. Collectively, our results shed light on a new role of osteoclasts in colitis in vivo, demonstrating they exert their colitogenic activity through an early action on hematopoiesis, leading to an increase in myelopoiesis sustaining gut inflammation.

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.

A 44-year-old woman who had been diagnosed with ulcerative colitis (UC) at 22 years old was diagnosed with severe flare-up of UC based on endoscopic findings associated with new-onset active pyoderma gangrenosum (PG) on both lower legs after she decided to discontinue UC treatment. Systemic treatment with intravenous prednisolone at 30 mg/day had achieved insufficient response to UC and PG, resulting in a diagnosis of corticosteroid-refractory UC and PG. Combination therapy with upadacitinib at 45 mg/day plus intensive granulocyte and monocyte adsorptive apheresis (GMA) was started to achieve clinical remission of UC. Ten weeks after starting this combination therapy, clinical improvement of UC was achieved with PG ulcer healing on both lower legs. A combination of upadacitinib plus intensive GMA may offer an effective therapeutic option for patients with active PG in addition to UC but has yet to be approved for induction or maintenance treatment of PG worldwide. PG is a dermatological involvement in UC patients that requires attention.

Extraintestinal manifestations occur rather frequently in ulcerative colitis (UC) and Crohn’s disease patients and are usually related to an exacerbation of the underlying intestinal bowel disease but sometimes may run a course independent of the inflammatory bowel diseases (IBD). About one-third of patients with IBD develop extraintestinal manifestations, such as pyoderma gangrenosum (PG). PG is an uncommon inflammatory skin disorder of unknown pathogenesis. There are no specific serological or histological markers, and diagnosis is predominantly clinical. Topical and systemic therapies are both vital aspects of treatment and immune modulators have been used with increasing success in recent years, although immunosuppressive drugs raise some concerns due to an increased risk of serious and opportunistic infections and cancer, particularly in elderly and comorbid patients, underlining the unmet need for safer alternative therapies. Thus, in this case report, we highlighted an adsorptive granulocyte/monocyte apheresis (GMA) as a new therapeutic possibility in IBD patients with extraintestinal manifestations. We report a case of a 60-year woman with a history of UC with a Mayo grade 3 score which was associated with a PG. Given that the patients maintained clinical remission with vedolizumab, we preferred not to perform a combined treatment with other antitumor necrosis factor-alpha or ciclosporin, thus avoiding an increased risk of serious infections in the patient. Therefore, we performed the extracorporeal leukocyte apheresis. The patient progressed favorably, with progressive improvement of skin and bowel disease. Therefore, adsorptive GMA has a very favorable safety profile and has been confirmed in numerous studies. In this study, we underlined that an intensive regimen of GMA paves the way to an ideal option for patients with severe and refractory PG complicated with UC.

Introduction: In recent years, the prevalence of inflammatory bowel diseases has been increasing in Japan due to the westernization of lifestyles. Many patients have been reported to have extra-intestinal manifestations (EIMs) at least once. Skin lesions occur with a high degree of frequency among EIMs, with erythema nodosum (EN) and pyoderma gangrenosum (PG) the main complications. Cytapheresis is again attracting attention as a treatment with few side effects. Methods: We investigated the therapeutic effect of cytapheresis on ulcerative colitis (UC) and cutaneous EIMs. Between 2008 and 2021, 240 patients with active UC had induction therapy by cytapheresis at our hospital. Results: Remission and response rates were 50.0% and 67.5%, respectively. Apheresis was performed on seven patients with PG and five patients with EN with a good response. Serious adverse events were not observed. Conclusion: This retrospective assessment of efficacy showed that EN and PG responded favorably to cytapheresis.

Pyoderma gangrenosum (PG), a chronic aseptic inflammatory skin disease characterized by skin ulcers with elevated and undermined borders, is resistant to conventional therapies. PG is elicited by activated neutrophils and macrophages and is often associated with systemic diseases such as inflammatory bowel disease, rheumatoid arthritis, aortitis syndrome, and hematopoietic disorders. This single-center study assessed the efficacy and safety of selectively depleting myeloid-lineage leukocytes in patients with PG. Patients with PG, aged 20 or over, received 5 or 10 treatment sessions of granulocyte and monocyte adsorption apheresis (GMA), once or twice a week. Treatment efficacy was assessed based on the rate of skin ulcer reduction, the visual analog scale of pain, and the physician’s global assessment of the skin lesions. A complete response (CR) was obtained in eight patients, a nearly complete response (nCR) in three patients, and a partial response (PR) in two patients. In four of the other six, the disease remained stable (SD) and in two we observed disease progression (PD). No severe adverse events were recorded. Our results suggest that GMA is a useful and safe treatment modality for PG.

An 18-year-old woman was admitted to our hospital with fever, diarrhea and painful skin ulcers in both pretibial areas starting 19 days earlier. The skin lesions appeared deep necrotic ulcers with violaceous undermined borders. She had been diagnosed as ulcerative colitis and primary sclerosing cholangitis (PSC) 6 and 5 years before, respectively, and had stopped having regular check-up and refused medication for years. Her clinical history and skin lesions led us to suspect of pyoderma gangrenosum (PG). The skin biopsy showed aseptic abscess formation with neutrophils infiltration in the dermis without bacteria. Thus, she was diagnosed with PG. 1 mg/kg/day of prednisolone was administered and ten sessions of granulocyte and monocyte adsorption apheresis (GMA) were started. Magnetic resonance cholangiography showed multifocal bile duct strictures due to PSC. Total colonoscopy revealed ulcerative pancolitis with spared normal mucosa in the rectum. After the treatments, her symptoms and the skin lesion improved dramatically. She was discharged on the 45th day with 25 mg/day of prednisolone. In conclusion, this is the first reported case of PG with PSC-associated colitis that showed dramatic response to the concomitant GMA therapy with corticosteroids. Together with previous reports, concomitant GMA therapy with corticosteroids may be an effective treatment for PG.
