Abstract
The arsenal of effective molecules to treat patients with chronic inflammatory bowel diseases (IBDs) remains limited. These remitting-relapsing diseases have become a global health issue and new therapeutic strategies are eagerly awaited to regulate the course of these disorders. Since the association between autophagy-related gene polymorphism and an increased risk of Crohn's disease (CD) has been discovered, a new domain of investigation has emerged, focused on the intracellular degradation system, with the objective of generating new medicines that are safer and more targeted. This review summarizes the drugs administered to IBD patients and describes recently emerged therapeutic agents. We compile evidence on the contribution of autophagy to IBD pathogenesis, give an overview of pharmacological autophagy regulators in animal models of colitis, and propose novel therapeutic avenues based on autophagy components.

Abstract
Fecal diversion with ostomy construction can be a temporary or definitive surgical measure for the treatment of refractory inflammatory bowel disease (IBD). However, the fecal diversion surgery is associated with various stoma, peristomal complications, and recurrence or occurrence of de novo small bowel Crohn's disease (CD). Stoma complications often need enterostomal therapy or surgical revision. Peristomal cutaneous lesions, such as pyoderma gangrenosum, usually require immunomodulator or biological therapy. Routine monitoring for occurrence or recurrence of CD with endoscopy or imaging should be performed, and prophylaxis with mesalamines, antibiotics, immunomodulators, or anti-TNFα or anti-integrin agents is needed for patients at risk. Those agents, along with corticosteroids, may also be used for the treatment of CD of the neo-small intestine, particularly inflammatory and fistulizing phenotypes. Endoscopic balloon dilation or endoscopic stricturotomy via stoma is safe and feasible to treat short (<4-5 cm), straight strictures in the neo-small intestine. Medically or endoscopically refractory fibrostenotic disease usually requires surgical intervention, with bowel-sparing stricturoplasty being the surgical treatment of choice.

Abstract
One-third of patients with Crohn's disease (CD) present as stricturing phenotype characterized by progressive luminal narrowing and obstructive symptoms. The diagnosis and management of these patients have been intriguing and challenging. Immunomodulators and biologics have been successfully used in treating inflammatory and fistulizing CD. There are issues of efficacy and safety of biological agents in treating strictures in CD. Rapid mucosal healing from potent biological agents may predispose patients to the development of new strictures or worsening of existing strictures. On the other hand, strictures constitute one-fifth of the reasons for surgery in patients with CD. Disease recurrence is common at or proximal to the anastomotic site with the majority of these patients developing new endoscopic lesions within 1 year of surgery. The progressive nature of the disease with repetitive cycle of inflammation and stricture formation results in repeated surgery, with a risk of small bowel syndrome. There is considerable quest for bowel conserving endoscopic and surgical strategies. Endoscopic balloon dilation and stricturoplasty have emerged as valid alternatives to resection. Endoscopic balloon dilation has been shown to be feasible, safe, and effective for the short primary or anastomotic strictures. However, repeated dilations are often needed, and long-term outcomes of endoscopic balloon dilation remain to be investigated. The introduction of stricturoplasty has added another dimension to bowel saving strategy. Although postoperative recurrence rate after stricturoplasty is comparable with surgical resection, there are concerns for increased risk of malignancy in preserved bowel. Laparoscopic surgery has widely been performed with similar outcomes to open approach with fewer complications, quicker recovery, better cosmesis, and lower cost. All of these issues should be considered by physicians involved in the management of patients with stricturing CD.

[PMID: 26081839 DOI: 10.1111/apt.13288] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/18/2015] [Revised: 04/13/2015] [Accepted: 06/01/2015] [Indexed: 12/12/2022]
Abstract
BACKGROUND Certolizumab pegol (CZP) is Food and Drug Administration (FDA)-approved to treat Crohn's disease (CD). However, the efficacy and safety of CZP outside clinical trials are not well established. AIM To report the efficacy, safety and predictors of response to CZP in CD patients treated during a 6-year period since FDA-approval at a tertiary care centre. METHODS All CD patients who received CZP at our institution between 2008 and 2013 were evaluated through retrospective medical record-based review of steroid-free complete response (SCR), loss of response and safety. RESULTS A total of 358 patients were included. One hundred twelve patients (31.3%) and 189 (52.8%) received CZP as their second and third biological agent, respectively. The probability of SCR at 26 week was 19.9% (95% CI, 15.9-24.5). The probability of survival free of loss of response at 2 year was 45.7% (95% CI, 32.5-59.5). A predictor of SCR was age at CD diagnosis of >40 years old (hazard ratio, HR relative to those <17, 4.69; 95% CI, 1.75-12.61). Negative predictors included present perianal fistula (HR, 0.39; 95% CI, 0.16-0.98) and prior primary nonresponse to adalimumab (ADA; HR relative to secondary loss of response, 0.18; 95% CI, 0.04-0.76). Twenty-three patients (6.4%) experienced serious adverse events and 19 patients (5.3%) discontinued CZP due to adverse events. CONCLUSIONS Certolizumab pegol was both effective and well tolerated for the treatment of Crohn's disease in this large tertiary care centre enriched with biologics-exposed patients. It may be more effective in patients without early-aged Crohn's disease diagnosis, prior primary nonresponse to adalimumab and present perianal fistula.

Abstract
BACKGROUND Certolizumab pegol (CERT) is indicated for reducing the signs and symptoms of Crohn's disease (CD) and maintaining clinical response. Patients losing response received an extra "capture" re-induction dose in the PRECiSE 4 study. We examined the use of certolizumab in a retrospective cohort of patients with CD at a single inflammatory bowel disease center. METHODS We conducted a retrospective chart review of all adult patients with CD treated with CERT at the University of Chicago from April 22, 2008 to May 1, 2011. Demographics, disease characteristics, inflammatory bowel disease therapies, surgeries, CERT dosing, and clinical outcomes were recorded. Predictors of clinical response, re-induction dosing, and maintenance dose escalation were evaluated. Univariate, multivariate, and Kaplan-Meier analyses were performed for predictive variables of clinical response, re-induction dosing, and maintenance dose increases. RESULTS One hundred ten patients were identified; 23 were excluded. The remaining 87 patients had a sustained clinical response of 31.0%, remission of 14.9%, minimal or no response of 31.0%; 37.9% initially responded but lost response. In total, 35.6% of patients received a single re-induction dose of 400 mg after a mean of 29 weeks, predicted by prior anti-tumor necrosis factor (P = 0.007) and absence of perianal disease (P = 0.006); only 5 patients (16.1%) maintained a durable response or remission; 11.5% increased maintenance dosage after a mean of 50 weeks; all but 1 subsequently stopped CERT. CONCLUSIONS Some patients with CD (31%) achieved a sustained response. The majority of patients receiving re-induction dosing did not achieve a sustained clinical response. Previous treatment with anti-tumor necrosis factor therapy was associated with reduced responses, suggesting that CERT may be more effective as an initial anti-tumor necrosis factor therapy.

Abstract
Crohn's disease (CD) causes chronic inflammation of the gastrointestinal tract and leads to fluctuations between active disease and remission. Certolizumab pegol is one of the newer biological treatments for patients with moderate-to-severe CD. Certolizumab pegol was shown to be effective in CD patients achieving response and remission in both randomized and non-randomized studies, and is an alternative biological treatment for CD. The available data show that certolizumab pegol achieves similar therapeutic efficacy and health-related quality of life scores in CD patients as the other biological agents, but at a higher cost, if dose escalation of other biologics is not considered. Considering subcutaneous self-administration, and lower number and frequency of injections, patients may prefer certolizumab pegol over the other biological treatments.

Abstract
The axial spondyloarthritis (SpA) classification criteria cover both patients with ankylosing spondylitis and non-radiographic axial SpA. After failure of NSAIDs TNF-α-inhibitors (TNF-blockers) can be given to patients with active axial SpA. Until recently, the TNF-blockers infliximab, adalimumab, etanercept and golimumab are labeled for the treatment of active ankylosing spondylitis while for active nr-axSpA only adalimumab has been approved in Europe. The TNF-blocker certolizumab pegol has recently been evaluated in the RAPID-axSpA trial which is the first placebo-controlled randomized-controlled trial in the entire group of axial SpA. An elevated C-reactive protein and/ or evidence of bone marrow edema on MRI of the sacroiliac joints were required for inclusion in RAPID-axSpA, and patients could have been preexposed to TNF-blockers. The interesting data of this important trial in the context of the emerging therapeutic field of non-radiographic axial SpA therapy is discussed in this review.

Abstract
Inflammatory bowel disease, including its 2 entities ulcerative colitis and Crohn's disease, is a chronic medical condition characterized by the destructive inflammation of the intestinal tract. Biologics represent a class of therapeutics with immune intervention potential. These agents block the proinflammatory cascade that triggers the activation and proliferation of T lymphocytes at the level of the intestine, therefore reestablishing the balance between the pro- and anti-inflammatory messages. All 7 biologics showing clinical benefits in inflammatory bowel disease are monoclonal antibodies. The following systematic review discusses the pharmacokinetics and efficacy of the tumor necrosis factor blockers infliximab, adalimumab, certolizumab pegol, and golimumab. In addition, we describe the α4 integrin inhibitors natalizumab and vedolizumab, which are directed against cell adhesion molecules, as well as the interleukin 12/23 blocker ustekinumab.

Abstract
Inflammatory bowel disease is a chronic inflammatory disorder of the gastrointestinal tract that includes both Crohn disease (CD) and ulcerative colitis. Abdominal pain, rectal bleeding, diarrhea, and weight loss characterize both CD and ulcerative colitis. The incidence of IBD in the United States is 70 to 150 cases per 100,000 individuals and, as with other autoimmune diseases, is on the rise. CD can affect any part of the gastrointestinal tract from the mouth to the anus and frequently will include perianal disease. The first description connecting regional enteritis with perianal disease was by Bissell et al in 1934, and since that time perianal disease has become a recognized entity and an important consideration in the diagnosis and treatment of CD. Perianal Crohn disease (PCD) is defined as inflammation at or near the anus, including tags, fissures, fistulae, abscesses, or stenosis. The symptoms of PCD include pain, itching, bleeding, purulent discharge, and incontinence of stool. In this report, we review and discuss the etiology, diagnosis, evaluation, and treatment of PCD.

Abstract
The management of patients with IBD requires evaluation with objective tools, both at the time of diagnosis and throughout the course of the disease, to determine the location, extension, activity and severity of inflammatory lesions, as well as, the potential existence of complications. Whereas endoscopy is a well-established and uniformly performed diagnostic examination, the implementation of radiologic techniques for assessment of IBD is still heterogeneous; variations in technical aspects and the degrees of experience and preferences exist across countries in Europe. ECCO and ESGAR scientific societies jointly elaborated a consensus to establish standards for imaging in IBD using magnetic resonance imaging, computed tomography, ultrasonography, and including also other radiologic procedures such as conventional radiology or nuclear medicine examinations for different clinical situations that include general principles, upper GI tract, colon and rectum, perineum, liver and biliary tract, emergency situation, and the postoperative setting. The statements and general recommendations of this consensus are based on the highest level of evidence available, but significant gaps remain in certain areas such as the comparison of diagnostic accuracy between different techniques, the value for therapeutic monitoring, and the prognostic implications of particular findings.

Abstract
INTRODUCTION Crohn's disease (CD) is a chronic, idiopathic, inflammatory bowel disease with no known cure. In those patients with moderate to severe disease, the result is often a clinically debilitating condition. In the last decade, one of the most significant developments in therapy has been a class of biological agents that neutralize TNFa. Certolizumab pegol (CZP) is the most recently FDA approved anti-TNF agent for the induction and maintenance of moderate to severely active Crohn's disease. AREAS COVERED The currently available evidence regarding the use of CZP in CD, the expected efficacy and possible adverse events associated with this population. EXPERT OPINION CZP is a TNFa inhibitor that is a safe and effective agent for treatment of CD. It has several unique features which make it useful in patients with moderate to severe disease.

Abstract
Gut inflammation occurring in patients with inflammatory bowel diseases (IBD) is associated with an excessive immune response that is directed against constituents of the normal bacterial flora and results in the production of large amounts of inflammatory cytokines. Anti-cytokine compounds, such as the neutralizing TNF antibodies, have been employed with clinical success in patients with IBD. However, nearly half of IBD patients are refractory to such treatments, response can wane with time, and anti-TNF treatment can associate with severe side effects and/or development/exacerbation of extra-intestinal immune-mediated pathologies. These observations, and the demonstration that, in IBD, the pathological process is also characterized by defects in the production and/or activity of counter-regulatory cytokines, have boosted further studies aimed at delineating novel strategies to combat the IBD-associated tissue-damaging immune response.

Abstract
The introduction of biological agents (i.e. antitumour necrosis factor-α and anti-integrin treatments) for the treatment of inflammatory bowel disease (IBD) [i.e. Crohn's disease (CD) and ulcerative colitis] has led to a substantial change in the treatment algorithms and guidelines, especially in CD. However, many questions still remain about the true efficacy and the best treatment regimens. Thus, a need for further treatment options still exists as up to 40% of IBD patients treated with the presently available biologicals do not have positive clinical responses. Better patient selection might maximize the clinical benefit for those in most need of an effective therapy to avoid disabling disease whilst also minimizing the complications associated with therapy. Further, the 'trough-level strategy' may help clinicians to optimize therapy and to avoid loss of response and/or immunogenicity. The idea behind this dosage regimen is that correct dosing must ensure that the patient's lowest level of drug concentration (i.e. the trough level) occurring just before the next drug administration is high enough for the full effect to be seen. Controversy continues regarding the appropriate use of biologicals; therefore, in this review, we focus on considerations that might lead to a more rational strategy for antitumour necrosis factor-α agents in IBD, emphasizing the situations in which the risks may outweigh the benefits. Finally, the need for an appropriate strategy for stopping biological treatment is discussed.

Efficacy and safety of certolizumab pegol in an unselected crohn's disease population: 26-week data of the FACTS II survey. Inflamm Bowel Dis 2011; 17:1530-9. [PMID: 21674709 DOI: 10.1002/ibd.21521] [Citation(s) in RCA: 17] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/22/2010] [Accepted: 09/10/2010] [Indexed: 12/09/2022]
Abstract
BACKGROUND Certolizumab pegol (Cimzia, CZP) was approved for the treatment of Crohn's disease (CD) patients in 2007 in Switzerland as the first country worldwide. This prospective phase IV study aimed to evaluate the efficacy and safety of CZP over 26 weeks in a multicenter cohort of practice-based patients. METHODS Evaluation questionnaires at baseline, week 6, and week 26 were completed by gastroenterologists in hospitals and private practices. Adverse events were evaluated according to World Health Organization (WHO) guidelines. RESULTS Sixty patients (38F/22M) were included; 53% had complicated disease (stricturing or penetrating), 45% had undergone prior CD-related surgery. All patients had prior exposure to systemic steroids, 96% to immunomodulators, 73% to infliximab, and 43% to adalimumab. A significant decrease of the Harvey-Bradshaw Index (HBI) was observed under CZP therapy (12.2 ± 4.9 at week 0 versus 6.3 ± 4.7 at week 6 and 6.7 ± 5.3 at week 26, both P < 0.001). Response and remission rates were 70% and 40% (week 6) and 67% and 36%, respectively (week 26). The complete perianal fistula closure rate was 36% at week 6 and 55% at week 26. The frequency of adverse drug reactions attributed to CZP was 5%. CZP was continued in 88% of patients beyond week 6 and in 67% beyond week 26. CONCLUSIONS In a population of CD patients with predominantly complicated disease behavior, CZP proved to be effective in induction and maintenance of response and remission. This series provides the first evidence of CZP's effectiveness in perianal fistulizing CD in clinical practice.

Abstract
During the last decade a large number of biological agents against tumor necrosis factor-α (TNF-α), as well as many biochemical substances and molecules specifically for the medical treatment of patients with inflammatory bowel disease (IBD), have been developed. This enormous progress was a consequence of the significant advances in biotechnology along with the increased knowledge of the underlying pathophysiological mechanisms involved in the pathogenesis of IBD. However, conventional therapies remain the cornerstone of treatment for most patients. During recent years conventional and biologic IBD therapies have been optimized. Newer mesalazine formulations with a reduced pill size and only one dose per day demonstrate similar efficacy to older formulations. New corticosteroids retain the efficacy of older corticosteroids while exhibiting a higher safety profile. The role of antibiotics and probiotics has been further clarified. Significant progress in understanding thiopurine metabolism has improved the effective dose along with adjunctive therapies. Quite a large number of substances and therapies, including biologic agents other than TNF-α inhibitors, unfractionated or low-molecular-weight heparin, omega-3 polyunsaturated fatty acids, microbes and microbial products, leukocytapheresis, and other substances under investigation, could offer important benefits to our patients. In this paper we review the established and emerging therapeutic strategies in patients with Crohn’s disease and ulcerative colitis.

Abstract
In the last 10 years, anti-tumor necrosis factor (TNF)-α therapy has become a cornerstone in the management of autoimmune diseases. Clinical trial data have consistently found that infliximab, adalimumab, and recently certolizumab pegol offer therapeutic benefits to patients with inflammatory bowel diseases (Crohn's disease and ulcerative colitis). Recent understanding on how these monoclonal antibodies evoke changes at the physiological and molecular levels have provided insights into disease pathogenesis and helped to identify new targets for future drug therapy. With increased experience in the use of these anti-TNF-α antibodies the long-term safety data, use in pregnancy have become available. This article provides an overview of the current knowledge regarding anti-TNF-α therapies for clinicians caring for patients with Crohn's disease and ulcerative colitis.
