This study examined the long-term maintenance rate after inducing remission by intensive granulocyte/monocyte adsorptive apheresis (GMA) without use of corticosteroids (CS) and GMA re-treatment efficacy in the same patients upon relapse with ulcerative colitis. Patients who achieved clinical remission and mucosal healing (MH) by first-time intensive GMA (first GMA) without CS were enrolled. The cumulative non-relapse survival rate up to week 156 was calculated. Patients with relapse during the maintenance period underwent second-time intensive GMA (second GMA) without CS. Clinical remission and MH rates following second GMA were compared to those following first GMA in the same patients. Of the 84 patients enrolled, 78 were followed until week 156 and 34 demonstrated relapse. The cumulative non-relapse survival rate by week 156 was 56.4%. Clinical remission and MH rates after second GMA did not differ from those after first GMA in the same patients (week 6: clinical remission, 100% vs 88.4%, p = 0.134; MH, 100% vs 84.8%, p = 0.074). In conclusion, MH induction by intensive GMA without use of CS in ulcerative colitis patients contributes to subsequent long-term clinical remission maintenance. GMA re-treatment efficacy was comparable to that of first GMA in the same patients who had relapse.

Granulocyte and monocyte adsorption apheresis (GMA) is an extracorporeal circulation therapy that removes activated granulocytes and monocytes, which can be easily introduced in clinics and hospitals where hemodialysis is performed. Its safety profile  allows for its administration without screening and for its concomitant use with other therapies, indicating that GMA can be a good additional option for GPP treatment. However, the evidence for its efficacy and safety is limited because of the rarity of GPP. Furthermore, its immediate impact on GPP has not been assessed yet. Therefore, we report our real-world experience of 14 patients with GPP treated with GMA after systemic treatment.GMA can be administered with other systemic therapies, including biologics and conventional therapy (objective A). Furthermore, its good safety profile allows GMA administration to a wide range of patients, including elderly patients and those with complications, possible active infection, or malignancy (objectives B and C). Moreover, our study revealed an immediate significant improvement in BT, accompanied by slight decreases in the WBC count and CRP level, indicating that GMA contributes to the rapid suppression of acute inflammation in patients with GPP.

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.

Generalized pustular psoriasis (GPP) is a rare, severe neutrophilic skin disorder characterized by sudden widespread eruption of superficial sterile pustules with or without systemic inflammation. GPP flares can be life-threatening if untreated due to potential severe complications such as cardiovascular failure and serious infections. Currently, there are no GPP-specific therapies approved in the USA or Europe. Retinoids, cyclosporine, and methotrexate are the most commonly used non-biologic therapies for GPP. The evidence that supports the currently available treatment options is mainly based on case reports and small, open-label, single-arm studies. However, recent advances in our understanding of the pathogenic mechanisms of GPP and the identification of gene mutations linked to the disease have paved the way for the development of specific targeted therapies that selectively suppress the autoinflammatory and autoimmune mechanisms induced during GPP flares. Several biologic agents that target key cytokines involved in the activation of inflammatory pathways, such as tumor necrosis factor-α blockers and interleukin (IL)-17, IL-23, and IL-12 inhibitors, have emerged as potential treatments for GPP, with several being approved in Japan. The evidence supporting the efficacy of these agents is mainly derived from small, uncontrolled trials. A notable recent advance is the discovery of IL36RN mutations and the central role of IL-36 receptor ligands in the pathogenesis of GPP, which has defined key therapeutic targets for the disease. Biologic agents that target the IL-36 pathway have demonstrated promising efficacy in patients with GPP, marking the beginning of a new era of targeted therapy for GPP.

Coronavirus disease 2019 (COVID-19), caused by infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), is now a pandemic. Although several treatment guidelines have been proposed for patients who have both inflammatory bowel disease and COVID-19, immunosuppressive therapy is essentially not recommended, and the treatment options are limited. Even in the COVID-19 pandemic, adjuvant adsorptive granulocyte and monocyte apheresis may safely bring ulcerative colitis (UC) into remission by removing activated myeloid cells without the use of immunosuppressive therapy. Our patient was a 25-year-old Japanese male with UC and COVID-19. This is the first case report of the induction of UC remission with granulocyte and monocyte apheresis treatment for active UC associated with COVID-19.

Inflammatory bowel disease (IBD), as a global disease, has attracted much research interest. Constant research has led to a better understanding of the disease condition and further promoted its management. We here reviewed the conventional and the novel drugs and therapies, as well as the potential ones, which have shown promise in preclinical studies and are likely to be effective future therapies. The conventional treatments aim at controlling symptoms through pharmacotherapy, including aminosalicylates, corticosteroids, immunomodulators, and biologics, with other general measures and/or surgical resection if necessary. However, a considerable fraction of patients do not respond to available treatments or lose response, which calls for new therapeutic strategies. Diverse therapeutic options are emerging, involving small molecules, apheresis therapy, improved intestinal microecology, cell therapy, and exosome therapy. In addition, patient education partly upgrades the efficacy of IBD treatment. Recent advances in the management of IBD have led to a paradigm shift in the treatment goals, from targeting symptom-free daily life to shooting for mucosal healing. In this review, the latest progress in IBD treatment is summarized to understand the advantages, pitfalls, and research prospects of different drugs and therapies and to provide a basis for the clinical decision and further research of IBD.

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.

Pustular psoriasis is a chronic inflammatory skin disease characterized by erythematous plaques with sterile pustules. It includes the distinct clinical entities generalized pustular psoriasis (GPP), acrodermatitis continua of Hallopeau (ACH) and palmoplantar pustular psoriasis (PPPP). Recently clarified pathomechanisms of pustular psoriasis indicate that hyperactivation of the skin innate immunity, including of the IL-1/IL-36 axis, plays an important role in the pathogenesis of pustular psoriasis. Autoinflammatory keratinization disease (AiKD) is the umbrella clinical entity for inflammatory keratinization disorders with genetic autoinflammatory pathomechanisms, and pustular psoriasis is a representative AiKD. To date, mutations/variants in five genes-IL36RN, CARD14, AP1S3, MPO and SERPINA3-have been reported to be genetic causative or predisposing factors for pustular psoriasis. The pathogenic mechanisms induced by the mutations/variants in these genes are all closely related to the excessive activation of skin innate immunity and autoinflammation. A number of biologics (e.g., tumor necrosis factor inhibitors, IL-17/IL-17 receptor inhibitors and IL-23 inhibitors) and granulocyte and monocyte adsorption apheresis are used to treat pustular psoriasis. Recently, based on novel information on the pathomechanisms of pustular psoriasis, which are mainly associated with autoinflammation, inhibitors of several pathogenic pathways, including of the IL-1, IL-36, IL-8 and granulocyte colony-stimulating factor signaling pathways, have been studied as emerging treatments.
