An Update on Current Pharmacotherapeutic Options for the Treatment of Ulcerative Colitis
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 adsorptive apheresis (GMA) is occasionally introduced as an alternative combination therapy after loss of response to biologics in ulcerative colitis (UC) patients. However, there have been no reports of the concomitant use of vedolizumab (VDZ) and GMA for the initial induction of UC. A 20-year-old man with refractory UC was admitted for recrudescence. VDZ monotherapy had previously been introduced but was ineffective. Therefore, he received scheduled combination of VDZ and GMA and achieved clinical remission. The combination of two different approaches to inhibit the migration of leukocytes into the inflamed tissue led to satisfactory clinical outcomes.
The combination of granulocyte-monocyte apheresis and vedolizumab: A new treatment option for ulcerative colitis?
Objectives: To assess the effectiveness and safety of combining granulocyte-monocyte apheresis (GMA) and vedolizumab (VDZ) in patients with refractory ulcerative colitis (UC). Methods: This retrospective, multicentre pilot study included all UC patients receiving both GMA and VDZ. We recorded data on GMA sessions, demographic characteristics, and clinical response. Effectiveness was assessed 1 and 6 months after finishing the GMA using the partial Mayo score, C-reactive protein, and fecal calprotectin levels. Data were also compiled on VDZ intensification, use of new immunomodulators and colectomy during follow-up. Results: Eight patients were included (mean age 46 years; 63% female; mean disease duration, 132 months; 50% E3). GMA was started after a loss of response to VDZ in all cases (25% primary nonresponse and 75% secondary loss of response). All had previously received anti-TNF agents. VDZ was prescribed as the second-, third-, or fourth-line biologic in 37%, 50%, and 13% of cases, respectively. Patients had a mean baseline partial Mayo score of 7.5 (SD 2.1) and received a median of 15 GMA sessions (range 5-38). After a median follow-up of 7.5 months (IQR 5-12), partial Mayo score decreased after 1 and 6 months (P = .01 and .06, respectively). Three patients (38%) achieved steroid-free clinical remission and five (63%) withdrew VDZ. Colectomy rate was 38%. No adverse events were observed during the combination therapy. Conclusions: This small case series suggests that combining GMA with VDZ could be a treatment option in selected cases of UC with an inadequate response to this biologic agent.
Combination therapy with cytapheresis plus vedolizumab in a corticosteroid-dependent patient with ulcerative colitis and previous ANTI-TNF-drug failure
We have reported the first case of using GMA in combination with vedolizumab in a patient with active, steroid-dependent UC with an inadequate response to vedolizumab and previous biologic failure to adalimumab and infliximab, achieving remission in the follow-up. It is believed that the primary consequence of GMA therapy is a selective depletion of certain subsets of myeloid leucocytes, the most relevant of which could be the CD14+ CD16+ DR++phenotype, also known as the proinflammatory monocytes.This selective depletion of circulating leucocytes could enhance the reduction of gut trafficking of leucocytes induced by vedolizumab and modify the concentration of proinflammatory cytokines. In this clinical context, GMA therapy could be a safe, on pharmacological treatment that could help to reduce the inflammatory load, thereby enhancing the effect of biologic drugs.
