Abstract
BACKGROUND Tofacitinib, as inhibitor of Janus kinases (JAK), interrupts the transmission of numerous pro-inflammatory cytokines involved in the pathogenesis of inflammatory bowel diseases (IBD). Therefore, tofacitinib provides a potent option to treat ulcerative colitis (UC). Besides the anti-inflammatory potential, inhibition of widespread JAKs carries the risk of side effects. Macrophages are involved in the form of different subtypes in inflammation, wound healing, and even coagulation. This study aimed to explore the balanced use of tofacitinib in M1-like as well as M2-like macrophages of healthy donors and patients with IBD. METHODS Monocytes of healthy donors and patients with chronic courses of IBD were obtained from blood samples. Macrophage colony-stimulating factor (M-CSF)-derived macrophages were treated with tofacitinib (1 µM, 5 µM, 10 µM) and polarized with either lipopolysaccharide and interferon (IFN)-γ towards M1-like-phenotype or with interleukin (IL)-4 towards M2-like-phenotype. ELISA and flow cytometry were used to evaluate cytokine levels and surface molecules. RESULTS Tofacitinib had a modulating effect on M1-like macrophages whereby the effect on pro-inflammatory cytokines (TNF-α, IL-6, IL-1β, IL-12, IL-23) was less pronounced than the induction of anti-inflammatory IL-10. However, during M2-like polarization tofacitinib impaired the development of the corresponding phenotype becoming evident through decreased IL-10 levels and CD206 expression in treated macrophages. In both phenotypes, tofacitinib strongly downregulated the expression of immunostimulatory molecules (CD80, CD86, CD83, CD40). Furthermore, a dose-dependent correlation between treatment with tofacitinib and expressed tissue factor was noticed. CONCLUSIONS Tofacitinib influences both polarizations (M1/M2) and the expression of tissue factor in a dose-dependent manner.

Dig Liver Dis 2023; 55:1311-1317. [PMID: 37316363 DOI: 10.1016/j.dld.2023.05.021] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/07/2023] [Revised: 05/19/2023] [Accepted: 05/23/2023] [Indexed: 06/16/2023]
Abstract
BACKGROUND Despite rescue therapy, acute severe ulcerative colitis (ASUC) is associated with a high risk of colectomy, while treatment options remain limited. Tofacitinib, a rapidly acting Janus Kinase (JAK) inhibitor, is gaining ground as an effective alternative treatment option for the management of acute severe ulcerative colitis, which may prevent emergency colectomy. METHODS A systematic literature search of PubMed and Embase was undertaken for studies of adult patients with ASUC treated with tofacitinib. RESULTS In total, two observational studies, seven case series and five case reports incorporating 134 patients who received tofacitinib in ASUC were identified with a follow-up period ranging from 30 days to 14 months. Overall, the pooled colectomy rate was 23.9% (95% CI 16.6-31.2). The pooled 90-day and 6-month colectomy free rate were 79.9% (95% CI 73.1-86.7) and 71.6% (95% CI 64-79.2) respectively. The most frequent adverse event was C. Difficile infection. CONCLUSIONS Tofacitinib appears to be a promising option for the treatment of ASUC. Randomized clinical trials are required to further access the efficacy, safety and optimal dose of tofacitinib in cases of ASUC.

Abstract
BACKGROUND Tofacitinib has emerged as a new potential treatment for acute severe ulcerative colitis [ASUC]. We conducted a systematic review to assess efficacy, safety and integration in ASUC algorithms. METHODS Systematic searching was done in MEDLINE, EMBASE, Cochrane Library and Clinicaltrials.gov until August 17, 2022, including all studies reporting original observations on tofacitinib for ASUC, preferably defined according to Truelove and Witts criteria. The primary outcome was colectomy-free survival. RESULTS Of 1072 publications identified, 21 studies were included of which three were ongoing clinical trials. The remaining comprised a pooled cohort originating from 15 case publications [n = 42], a GETAID cohort study [n = 55], a case-control study [n = 40 cases] and a paediatric cohort [n = 11]. Of these 148 reported cases, tofacitinib was used as second-line treatment after steroid failure in previous infliximab failures or third-line after sequential steroid and infliximab or cyclosporine failure, 69 [47%] were female, median age range was 17-34 years and disease duration was 0.7-10 years. Overall, 30-day colectomy-free survival was 85% [n = 123 of 145; n = 3 without colectomy had follow-up <30 days], 90-day 86% [n = 113 of 132; n = 16 follow-up <90 days] and 180-day 69% [n = 77 of 112; n = 36 follow-up <180 days]. Tofacitinib persistence at follow-up was 68-91%, clinical remission 35-69% and endoscopic remission 55%. Adverse events occurred in 22 patients, predominantly being infectious complications other than herpes zoster [n = 13], and resulted in tofacitinib discontinuation in seven patients. CONCLUSION Tofacitinib appears promising for treatment of ASUC with high short-term colectomy-free survival among refractory patients who are otherwise deemed to require colectomy. However, large high-quality studies are needed.

Ileocolonic-Targeted JAK Inhibitor: A Safer and More Effective Treatment for Inflammatory Bowel Disease. Pharmaceutics 2022; 14:2385.

Abstract
Janus kinase (JAK) inhibitors, such as tofacitinib (Xeljanz) and filgotinib (Jyseleca), have been approved for treatment of ulcerative colitis with several other JAK inhibitors in late-stage clinical trials for inflammatory bowel disease (IBD). Despite their impressive efficacy, the risk of adverse effects accompanying the use of JAK inhibitors has brought the entire class under scrutiny, leading to them receiving an FDA black box warning. In this study we investigated whether ileocolonic-targeted delivery of a pan-JAK inhibitor, tofacitinib, can lead to increased tissue exposure and reduced systemic exposure compared to untargeted formulations. The stability of tofacitinib in the presence of rat colonic microbiota was first confirmed. Next, in vivo computed tomography imaging was performed in rats to determine the transit time and disintegration site of ileocolonic-targeted capsules compared to gastric release capsules. Pharmacokinetic studies demonstrated that systemic drug exposure was significantly decreased, and colonic tissue exposure increased at 10 mg/kg tofacitinib dosed in ileocolonic-targeted capsules compared to gastric release capsules and an oral solution. Finally, in a rat model of LPS-induced colonic inflammation, targeted tofacitinib capsules significantly reduced concentrations of proinflammatory interleukin 6 in colonic tissue compared to a vehicle-treated control (p = 0.0408), unlike gastric release tofacitinib capsules and orally administered dexamethasone. Overall, these results support further development of ileocolonic-targeted tofacitinib, and potentially other specific JAK inhibitors in pre-clinical and clinical development, for the treatment of IBD.

Exploring the Molecular Mechanism of Tong Xie Yao Fang in Treating Ulcerative Colitis Using Network Pharmacology and Molecular Docking. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2022; 2022:8141443. [PMID: 36204124 PMCID: PMC9532093 DOI: 10.1155/2022/8141443] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/28/2022] [Revised: 08/29/2022] [Accepted: 09/05/2022] [Indexed: 11/18/2022]
Abstract
Objective. The purpose of this study was to investigate the mechanisms of action of Tong Xie Yao Fang (TXYF) against ulcerative colitis (UC) by employing a network pharmacology approach. Methods. The network pharmacology approach, including screening of the active ingredients and targets, construction of the active ingredient-drug target network, the active ingredient-diseasetarget network, the protein–protein interaction (PPI) network, enrichment analyses, molecular docking, and targets validation, was used to explore the mechanisms of TXYF against UC. Results. 34 active ingredients and 129 and 772 targets of TXYF and UC, respectively, were identified. The intersection of the active ingredient-drug target network, the active ingredient-disease target network, and the PPI network suggested that kaempferol, beta-sitosterol, wogonin, and naringenin were the core ingredients and prostaglandin-endoperoxide synthase 2 (PTGS2) was the core target. Enrichment analyses showed that regulation of exogenous protein binding and other functions were of great significance. Nuclear factor-kappa B (NF-κB) signaling pathway, interleukin-17 (IL-17) signaling pathway, and tumor necrosis factor (TNF) signaling pathway were important pathways. Results of molecular docking indicated that the core ingredients and the target molecule had strong binding affinities. We have validated the high levels of expression of PTGS2 in UC by analyzing three additional datasets from the Gene Expression Omnibus (GEO) database. Conclusions. There are multiple ingredients, targets, and pathways involved in TXYF’s effectiveness against UC, and these findings will promote further research and clinical applications.

Abstract
Acute severe colitis (ASC) may occur within 3 months of ulcerative colitis diagnosis in 9%-15% of children and the rate of colectomy is up to 40%-50% within 5 years after an ASC. The aim of this publication is to present recent and relevant data on the success of medical treatment with tofacitinib in ASC. Methods We report a challenging case of a teenage boy with ASC at diagnosis and conduct a discussion after a review of the literature regarding the use of tofacitinib in inflammatory bowel disease, especially in pediatric patients and in ASC. Results The patient was hospitalized for 10 weeks and was refractory to conventional therapies: intravenous corticosteroids, infliximab, methotrexate, and vedolizumab. He received 7 blood transfusions and also presented with a severe malnutrition requiring a total parenteral nutrition. Tofacitinib was considered as a medical last resort before colectomy and was started at week 8. Thirteen days after starting tofacitinib, he was asymptomatic and was discharged on tofacitinib as sole treatment. By week 9 of tofacitinib, a colonoscopy showed both endoscopic and histological remission. He has remained in clinical remission at 6-month follow-up. Conclusions Tofacitinib may be an alternative medical treatment to avoid colectomy in ASC. It is a small molecule with a rapid onset and few severe adverse events. It has been used for ASC in adult patients, allowing to avoid colectomy in more than 60%. To our knowledge, this is one of the few pediatric patients with refractory ASC at initial diagnosis who responded to tofacitinib.

Abstract
Inflammatory bowel diseases, comprising ulcerative colitis (UC) and Crohn's disease, are chronic, immune-mediated and progressive inflammatory disorders affecting the gastrointestinal tract. Tofacitinib is the first oral small-molecule Janus kinase (JAK) inhibitor licensed and approved by the National Institute for Health and Care Excellence (NICE) for use in moderately-to-severely active UC after intolerance, inadequate response, or loss of response to conventional treatment or biologic therapy. The pivotal OCTAVE studies demonstrated the efficacy and safety of tofacitinib for the induction and maintenance of remission in UC. A growing body of evidence from real-world data supports the positive clinical and endoscopic benefits observed with tofacitinib treatment in the OCTAVE trials. This narrative review summarizes the current literature regarding the mechanism of action of tofacitinib, data from registrational trials, emerging real-world evidence, and an overview of the most recent safety evidence. We explore evolving treatment paradigms, including the use of tofacitinib in the COVID-19 era, pregnancy and extraintestinal manifestations, as well as the emerging concept of combining tofacitinib with biological therapy. We will also present a brief overview of the next generation of JAK inhibitors in the pipeline.

Abstract
Crohn disease (CD) and ulcerative colitis (UC) are considered chronic disorders of the gastrointestinal tract, lifelong medication often being necessary. Furthermore, they have significant implications on the quality of life. In the past few years, major advances have been achieved concerning the treatment of inflammatory bowel disease. These advances are expanding the possibilities for managing these patients. Janus kinase (JAK) inhibitors represent the most auspicious treatment to date because they consist of drugs that are orally administered, with a short half-life and low antigenicity. In addition, they seem to concurrently lessen various proinflammatory routes. In fact, tofacitinib has already been approved in patients with UC, both naïve and with prior exposure to tumor necrosis factor inhibitors. In CD, the results with tofacitinib have been less impressive. Several other JAK inhibitors are currently being investigated. However, given the wide spectrum of immunosuppressive effects, special attention has been given to the safety profile of these drugs, namely with regard to the occurrence of thromboembolic events, opportunistic infections, and malignancy. In this article, we review key evidence on the efficacy and safety of JAK inhibitors concerning both UC and CD.

Tong Xie Yao Fang: A Classic Chinese Medicine Prescription with Potential for the Treatment of Ulcerative Colitis. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2021; 2021:5548764.

Abstract
The prescription of Tong Xie Yao Fang (TXYF) was derived from the Yuan dynasty “Dan Brook Heart Law,” which was a representative formula for treating liver-spleen disharmony, diarrhea, and abdominal pain. The prescription is composed of four herbs for soothing the liver and strengthening the spleen. TXYF is reportedly capable of eliminating discomfort in ulcerative colitis (UC). This classic formula has been widely used for regulating gastrointestinal motor dysfunction and repairing colon mucosa. This review aims to provide current information on the pharmacology and clinical research of TXYF in the treatment of UC, and to critically appraise that information, in order to guide the future clinical use and experimental study of TXYF in the treatment of UC. We searched online databases including PubMed, CNKI, and Google Scholar for research published between 2010 and 2020 on TXYF and its efficacy in the treatment of UC. The findings indicated that TXYF has anti-inflammatory and immunomodulatory effects, regulates cell signal transduction, brain-gut axis, and intestinal flora in UC, and may promote targeting of bone mesenchymal stem cells (BMSCs) to the colonic mucosa and accelerate healing of the colonic mucosal barrier. In addition, the results of clinical studies showed that TXYF has good efficacy and few adverse reactions in the treatment of UC. Although it has achieved some success, the research is limited by deficiencies; there is a lack of unified standards for the construction of UC animal models and for administration regimen. In addition, the dosage of TXYF is not consistent and lacks pharmacological verification, and clinical trial data are not detailed or sufficiently rigorous. Therefore, a more rigorous, comprehensive, and in-depth study of TXYF in the treatment of UC is needed.

Abstract
INTRODUCTION Despite significant advances in the study of Ulcerative colitis (UC) management, up to a third of patients may be refractory to conventional therapy, and specialists have considered natural compounds such as curcumin. AREA COVERED The meta-analyzes found in the literature compare the effects of curcumin used in different administration routes or compare patients in remission with patients with active disease. Due to the biases in these studies, we performed a systematic review and meta-analysis of randomized clinical trials (RCTs) that investigated the efficacy of orally administrated curcumin in mild-to-moderate active UC. EXPERT OPINION Curcumin produces relevant anti-inflammatory and antioxidant effects that are crucial in inducing remission in UC patients. Unfortunately, in the treatment of UC, we have not observed studies with standardization of dose and routes of administration. Existing meta-analyses are biased because they compare studies using different administration routes and patients in different stages of the disease. Our meta-analysis is the only one that tried to make a comparison with a few of biases as possible and show that curcumin can help in the induction of remission in UC subjects.

Abstract
Inflammatory bowel disease (IBD) includes Crohn's disease (CD) and ulcerative colitis (UC). These are chronic autoimmune diseases of unknown etiology affecting the gastrointestinal tract. The IBD population includes a heterogeneous group of patients with varying disease courses requiring personalized treatment protocols. The complexity of the disease often delays the diagnosis and the initiation of appropriate treatments. In a subset of patients, IBD leads to colitis-associated cancer (CAC). MicroRNAs are single-stranded regulatory noncoding RNAs of 18 to 22 nucleotides with putative roles in the pathogenesis of IBD and colorectal cancer. They have been explored as biomarkers and therapeutic targets. Both tissue-derived and circulating microRNAs have emerged as promising biomarkers in the differential diagnosis and in the prognosis of disease severity of IBD as well as predictive biomarkers in drug resistance. In addition, knowledge of the cellular localization of differentially expressed microRNAs is a prerequisite for deciphering the biological role of these important epigenetic regulators and the cellular localization may even contribute to an alternative repertoire of biomarkers. In this review, we discuss findings based on RT-qPCR, microarray profiling, next generation sequencing and in situ hybridization of microRNA biomarkers identified in the circulation and in tissue biopsies.
