The main goals of Ulcerative Colitis (UC) treatment are to both induce and maintain the clinical and endoscopic remission of disease, reduce the incidence of complications such as dysplasia and colorectal carcinoma and improve quality of life. Although a curative medical treatment for UC has not yet been found, new therapeutic strategies addressing specific pathogenetic mechanisms of disease are emerging. Notwithstanding these novel therapies, non-biological conventional drugs remain a mainstay of treatment. The aim of this review is to summarize current therapeutic strategies used as treatment for ulcerative colitis and to briefly focus on emerging therapeutic strategies, including novel biologic therapies and small molecules. To date, multiple therapeutic approaches can be adopted in UC and the range of available compounds is constantly increasing. In this era, the realization of well-designed comparative clinical trials, as well as the definition of specific therapeutic models, would be strongly suggested in order to achieve personalized management for UC patients. They also presented other non-Pharmacological Therapies for UC including probiotics, cytapheresis and fecal transplantation.

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.

• Existen 2 dispositivos de granulocitoféresis: Cellsorba^® (fibras de poliéster no tejidas), que fija granulocitos y linfocitos, y Adacolumn^® (acetato de celulosa) que fija selectivamente granulocitos y monocitos.
• Además de retirar leucocitos activados, la aféresis produce incremento del número de granulocitos CD10-negativos (inmaduros), disminución de citocinas proinflamatorias (factor de necrosis tumoral alfa [TNF-α], interleucina [IL-6],IL-8 e IL-1β) e incremento de citocinas inhibitorias (IL-1, IL-10)
• La granulocitoféresis es un método razonablemente eficaz y seguro para obtener la remisión en niños con colitis ulcerosa corticodependiente o resistente, sobre todo en pacientes en el primer episodio, en enfermedad de corta evolución y en aquellos que no han recibido esteroides
• El procedimiento requiere 2 accesos venosos de buen flujo. La pauta más habitual de tratamiento consiste en 1–2 sesiones semanales de 60min a un flujo de 30ml/min, hasta un total de 5–10 sesiones

GMA is the only available therapy for UC directly targeting neutrophils. Two controlled, multicentre, European studies and a number of recent cases series found a potential therapeutic benefit of GMA in different clinical scenarios of UC with a still unmet need for optimal treatment. Moreover, GMA has an excellent safety profile and is perceived as a convenient procedure by patients, making this non-pharmacological therapy a suitable alternative or add-on therapy in UC, particularly for frail or comorbid patients.

The results support the hypothesis that patients with active UC have a better chance of clinical remission if GMA is administered as an adjunctive therapy. As regards the frequency of AEs, we found no statistically significant difference between the two groups. With regard to remission maintenance, GMA was identified as an effective alternative therapeutic option

Pyoderma gangrenosum (PG), acne(A), and Suppurative hidradenitis (SH) syndrome (PASHs) is a recently proposed disease entity clinically characterized by PG, acne, and SH, belonging to the spectrum of hereditary autoinflammatory syndrome with PG. Although biologic agents targeting interleukin-1 and tumor necrosis factor-α have been recommended for the treatment of PASHs, their efficacy has not been well established because of its rarity.
Granulocyte and monocyte adsorption apheresis is an extracorporeal apheresis unit designed to selectively remove pathogenic granulocytes and macrophages that produce proinflammatory cytokines. The efficacy of GMA on PG has been reported, and treatment of PASHs with GMA has been described in a single case report

Remission induction was more challenging in elderly UC patients. However, CAP was safe and effective for remission induction as a non-pharmacological treatment, even in elderly UC patients, after the incorporation of practical measures. Optimized and contrived CAP is still useful as the sole or concomitant treatment.

The apheresis techniques in pediatrics had been presented with few complications in our center, none derived from vascular access, anticoagulation, infections or adverse effects due to use of replacement fluid. The training of medical and nursing staff is essential to identify risk situations. The use of protocols and international guidelines ensure safety in pediatrics.

Single-needle (SN) apheresis may be safe and effective and may reduce patient burden during UC treatment. Nevertheless, further comparative studies are needed.
