[PMID: 38311005 DOI: 10.1016/j.gastrohep.2024.01.007] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/24/2023] [Revised: 12/31/2023] [Accepted: 01/18/2024] [Indexed: 02/06/2024]
Abstract
The treatment of inflammatory bowel disease has undergone a significant transformation following the introduction of biologic drugs. Thanks to these drugs, treatment goals have evolved from clinical response and remission to more ambitious objectives, such as endoscopic or radiologic remission. However, even though biologics are highly effective, a significant percentage of patients will not achieve an initial response or may lose it over time. We know that there is a direct relationship between the trough concentrations of the biologic and its therapeutic efficacy, with more demanding therapeutic goals requiring higher drug levels, and inadequate exposure being common. Therapeutic drug monitoring of biologic medications, along with pharmacokinetic models, provides us with the possibility of offering a personalized approach to treatment for patients with IBD. Over the past few years, relevant information has accumulated regarding its utility during or after induction, as well as in the maintenance of biologic treatment, in reactive or proactive strategies, and prior to withdrawal or treatment de-escalation. The aim of this document is to establish recommendations regarding the utility of therapeutic drug monitoring of biologics in patients with inflammatory bowel disease, in different clinical practice scenarios, and to identify areas where its utility is evident, promising, or controversial.

Abstract
The pathogenesis of inflammatory bowel disease (IBD) is still unclear. Immune dysfunction may play a key role in the pathogenesis of IBD, in which the role of CD4+ T helper (Th) cells is particularly important. Th17 cells are a major component of CD4+ T cells, and their differentiation is regulated by a variety of extracellular signals, transcription factors, RNA, and posttranslational modifications. Th17 cells specifically produce IL-17 and play an important role in the protection of mucous membranes and epithelial tissues against infection by extracellular microbes. However, when immune regulation is dysfunctional, Th17 cells abnormally proliferate and produce large amounts of proinflammatory cytokines that can recruit other inflammatory cells, which together induce abnormal immune responses and result in the development of many autoimmune diseases. In recent years, studies have confirmed that Th17 cells play an important role in the pathogenesis of IBD, which makes it a possible target for IBD therapy. This article reviews the recent progress of Th17 cells involved in the pathogenesis of IBD and its targeted therapy.

Abstract
Despite current guidelines, the optimal treatment of patients with inflammatory bowel disease (IBD) remains challenging. The available medications are not without risk and there is not a single correct treatment regimen for every patient. Personalizing treatment and selecting the most appropriate therapy is crucial for optimal response, remission, quality of life, and healthcare utilization. Biologics, especially anti-tumor necrosis factor-α medications, are widely used in the induction and maintenance of disease remission in patients with IBD. Similarly, immunomodulators, including thiopurines and methotrexate, are traditionally popular for the maintenance of remission. In this manuscript, we review the use of biologic monotherapy vs. combination therapy with immunomodulators for the treatment of ulcerative colitis and Crohn’s disease. We examine overall remission, immunogenicity and adverse effects, mainly serious infections and malignancy, in an effort to help guide treatment decisions and weigh the risks and benefits of biologic monotherapy vs. combination therapy.

Abstract
Autoimmune diseases (such as rheumatoid arthritis, asthma, autoimmune bowel disease) are a complex disease. Improper activation of the immune system or imbalance of immune cells can cause the immune system to transform into a proinflammatory state, leading to autoimmune pathological damage. Recent studies have shown that autoimmune diseases are closely related to CD4+ T helper cells (Th). The original CD4 T cells will differentiate into different T helper (Th) subgroups after activation. According to their cytokines, the types of Th cells are different to produce lineage-specific cytokines, which play a role in autoimmune homeostasis. When Th differentiation and its cytokines are not regulated, it will induce autoimmune inflammation. Autoimmune bowel disease (IBD) is an autoimmune disease of unknown cause. Current research shows that its pathogenesis is closely related to Th17 cells. This article reviews the role and plasticity of the upstream and downstream cytokines and signaling pathways of Th17 cells in the occurrence and development of autoimmune bowel disease and summarizes the new progress of IBD immunotherapy.

Abstract
Treatment strategies for inflammatory bowel disease (IBD) now increasingly target deep remission, yet the resultant more aggressive use of medical therapy is associated with potentially serious adverse events and significant costs. It is, therefore, of vital importance to consider when, how and in whom medical therapy may be safely de-escalated. This issue is of great potential relevance in the current SARS-Cov-2 pandemic. In this review, we first discuss the rationale for drug withdrawal in IBD, before considering the available data on withdrawal of 5-aminosalicylates (5-ASA), immunomodulators (IM) and biological therapy in both ulcerative colitis (UC) and Crohn's Disease (CD). We consider how to identify patients most appropriate for drug withdrawal and outline a potential monitoring strategy for the early detection of relapse following drug withdrawal. We conclude with important future perspectives in this challenging field, and highlight ongoing trials that are likely to shape practice in the years to come.

Abstract
BACKGROUND AND AIM It is unclear whether vedolizumab therapy can be discontinued in patients with inflammatory bowel disease [IBD] after achieving steroid-free clinical remission. The aim was to assess the risk of relapse after vedolizumab therapy was discontinued. METHODS This was a retrospective observational study, collecting data from 21 tertiary centres affiliated with the GETAID from January 2017 to April 2019. Consecutive patients with IBD, who were in steroid-free clinical remission for at least 3 months and were treated with vedolizumab for at least 6 months, were included at the time of vedolizumab discontinuation. RESULTS A total of 95 patients [58 with Crohn's disease] discontinued vedolizumab after a median duration of therapy of 17.5 [10.6-25.4] months. After a median follow-up period of 11.2 [5.8-17.7] months, 61 [64%] patients experienced disease relapse. The probabilities of relapse-free survival were 83%, 59%, and 36% at 6, 12, and 18 months, respectively. According to the multivariate analysis, a C-reactive protein level less than 5 mg/L at vedolizumab discontinuation (hazard ratio [HR] = 0.56, 95% confidence interval [CI] [0.33-0.95], p = 0.03) and discontinuation due to patients' elective choice (HR = 0.41, 95% CI [0.21-0.80], p = 0.009) were significantly associated with a lower risk of relapse. Re-treatment with vedolizumab was noted in 24 patients and provided steroid-free clinical remission in 71% and 62.5% at Week 14 and after a median follow-up of 11.0 [5.4-13.3] months, respectively, without any infusion reactions. CONCLUSIONS In this retrospective study, two-thirds of patients with IBD treated with vedolizumab experienced relapse within the first year after vedolizumab discontinuation. Re-treatment with vedolizumab was effective in two-thirds of patients.

Abstract
OBJECTIVE Inflammatory bowel disease (IBD) is increasingly managed with the use of biologic therapies. National guidelines (National Institute for Health and Care Excellence (NICE)) suggest considering cessation after 1 year of therapy but lack detailed criteria for this. We aimed to describe clinical outcomes from the introduction of a biologic review panel (BRP) to implement modified criteria for cessation of antitumour necrosis factor (anti-TNF) therapy and step down to single-agent immunomodulator. DESIGN Retrospective review of patient outcomes following BRP implementation. PATIENTS All patients on biologic therapy discussed in the BRP within a 5-year period. SETTING Single IBD network covering three hospital sites. INTERVENTIONS Modified criteria for biologic cessation were based on published evidence; they excluded individuals with no suitable maintenance immunomodulator, previous surgery or evidence of active disease, additional indications for anti-TNF therapy and previous relapse on biologic cessation. All patients with IBD on a biologic were discussed at the BRP. MAIN OUTCOME MEASURES Relapse following IBD cessation and relative cost of BRP. RESULTS 136 patients with IBD were reviewed, with 45 patients meeting the NICE guideline criteria for cessation. The BRP and modified criteria affected decision to withdraw therapy in 38% of these. Therapy was withdrawn in 27 patients, with a 20% 24-month relapse rate. Younger age at cessation was significantly associated with relapse (p=0.01). CONCLUSION The BRP approach has proved a safe and effective means of decision making in stopping biologic therapy. Future work to inform exclusion criteria is required.

The Clinical and Cost-Effectiveness of 4 Enzyme-Linked Immunosorbent Assay Kits for Monitoring Infliximab in Crohn Disease Patients: Protocol for a Validation Study. JMIR Res Protoc 2018; 7:e11218. [PMID: 30341052 PMCID: PMC6231806 DOI: 10.2196/11218] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/05/2018] [Revised: 08/07/2018] [Accepted: 08/07/2018] [Indexed: 12/29/2022] Open
Abstract
Background Currently, treatment decisions for people with Crohn disease are based on clinical judgment and trial and error. Consequently, people may continue to receive high drug dosages and experience unnecessary toxicity when it is possible to reduce or discontinue without a detrimental effect on clinical outcomes. Therapeutic drug monitoring (TDM) involves regularly testing blood samples for drug and antibody levels that could help clinicians identify the optimal treatment strategy and pre-empt treatment failure. However, heterogeneity in the assays can lead to a discrepancy in results and difficulties in decision-making. Standardization of the kits, and therefore results, would allow clinicians to optimize the use of biologics. Currently, there is also a lack of evidence for the cost-effectiveness of TDM using commercial test kits. Objective This study aims to analyze the clinical and cost-effectiveness of 4 commercial enzyme-linked immunosorbent assay (ELISA) kits (LISA TRACKER, IDKmonitor, Promonitor, and RIDASCREEN) to generate evidence which could support a recommendation for wider adoption in the National Health Service. Methods We propose to carry out a prospective-retrospective predictive biomarker validation study using the blood samples and clinical/utilization data collected during the ongoing SPARE trial (NCT02177071). A total of 200 stored samples from people with Crohn's disease who respond to treatment with infliximab will be used along with clinical and cost data from the trial. We will investigate the relationship between the drug and antidrug antibody levels with the main clinical outcomes (relapse rate at 2 years and time spent in remission), as well as resource utilization and quality of life. Results Funding is being sought to conduct this research. Conclusions This is the first study to compare the 4 ELISA kits for monitoring infliximab in patients with Crohn disease. It aims to address the uncertainties in the potential benefits of using the technologies for TDM. International Registered Report Identifier (IRRID) PRR1-10.2196/11218

Subtherapeutic Infliximab Trough Levels and Complete Mucosal Healing Are Associated With Sustained Clinical Remission After Infliximab Cessation in Paediatric-onset Crohn's Disease Patients Treated With Combined Immunosuppressive Therapy. J Crohns Colitis 2018; 12:644-652.

Abstract
BACKGROUND AND AIMS We aimed to investigate the outcome in paediatric-onset Crohn's disease patients who had discontinued infliximab after maintaining clinical remission with combined immunosuppression, and to determine factors associated with clinical relapse. METHODS We conducted a retrospective observational study of 63 paediatric-onset Crohn's disease patients who had stopped scheduled infliximab during sustained corticosteroid-free clinical remission for at least 1 year with infliximab and azathioprine, and were followed up for at least 1 year thereafter. Cumulative relapse rates and the median time to relapse were estimated statistically. Factors at cessation were also evaluated for their association with clinical relapse. RESULTS After a median follow-up period of 4.3 years [range, 1-7.5 years], 60.3% [38/63] of patients had experienced clinical relapse. According to Kaplan-Meier survival analysis, the estimated cumulative relapse rates at 1, 4, and 6 years were 19.0%, 62.2%, and 75.2%, respectively, and the median relapse time was 3.3 years from infliximab cessation. According to multivariate Cox proportional hazard regression analysis, infliximab trough levels of ≥2.5 μg/mL and incomplete mucosal healing were associated with clinical relapse (hazard ratio [HR] = 7.199, 95% confidence interval [CI] = 1.641-31.571, p = 0.009 and HR = 3.628, 95% CI = 1.608-8.185, p = 0.002, respectively). Although re-treatment with infliximab was effective in 90.9% [30/33] of patients, 7.9% [3/38] eventually underwent surgery within 1 year of relapse. CONCLUSIONS Considering the high cumulative relapse rates in the long term and cases of severe relapse requiring surgery, discontinuing infliximab in paediatric-onset Crohn's disease patients is currently inadvisable. However, there may be a subgroup of patients who are good candidates for infliximab withdrawal.

Abstract
Clinically effective therapies now exist for remission maintenance in both ulcerative colitis [UC] and Crohn's Disease [CD]. For each major class of IBD medications [5-aminosalicyclates, immunomodulators, and biologic agents], used alone or in combination, there is a risk of relapse following reduction or cessation of treatment. A consensus expert panel convened by the European Crohn's and Colitis Organisation [ECCO] reviewed the published literature and agreed a series of consensus practice points. The objective of the expert consensus is to provide evidence-based guidance for clinical practice so that physicians can make informed decisions in partnership with their patients. The likelihood of relapse with stopping each class of IBD medication is reviewed. Factors associated with an altered risk of relapse with withdrawal are evaluated, and strategies to monitor and allow early identification of relapse are considered. In general, patients in clinical, biochemical, and endoscopic remission are more likely to remain well when treatments are stopped. Reintroduction of the same treatment is usually, but not always, successful. The decision to stop a treatment needs to be individualized, and shared decision making with the patient should take place.

Abstract
The intestine is colonized by hundreds of different species of commensal bacteria, viruses, and fungi. Therefore, the intestinal immune system is constantly being challenged by foreign antigens. The immune system, the commensal microbiota, and the intestinal epithelial surface have to maintain a tight balance to guarantee defense against potential pathogens and to prevent chronic inflammatory conditions at the same time. Failure of these mechanisms can lead to a vicious cycle in which a perpetual tissue damage/repair process results in a pathological reorganization of the normal mucosal surface. This dysregulation of the intestine is considered to be one of the underlying causes for both inflammatory bowel disease (IBD) and colorectal cancer. TH17 cells have been associated with immune-mediated diseases, such as IBD, since their discovery in 2005. Upon mucosal damage, these cells are induced by a combination of different cytokines, such as IL-6, TGF-β, and IL-1β. TH17 cells are crucial players in the defense against extracellular pathogens and have various mechanisms to fulfill their function. They can activate and attract phagocytic cells. Additionally, TH17 cells can induce the release of anti-microbial peptides from non-immune cells, such as epithelial cells. The flip side of the coin is the strong potential of TH17 cells to be pro-inflammatory and promote pathogenicity. TH17 cells have been linked to both mucosal regeneration and inflammation. In turn, these cells and their cytokines emerged as potential therapeutic targets both for inflammatory diseases and cancer. This review will summarize the current knowledge regarding the TH17 cell-enterocyte crosstalk and give an overview of its clinical implications.

Abstract
Background It is crucial to determine whether infliximab (IFX) therapy could be safely interrupted in Crohn’s disease (CD) patients with clinical remission. The outcome and risk predictors of relapse after IFX therapy stopped are controversial. The aim was to assess the relapse and predictive factors after IFX discontinuation in CD patients with clinical remission. Methods A retrospective cohort of CD patients with clinical remission who discontinued scheduled IFX therapy at Nanfang Hospital were included. The primary outcome was relapse. All patients were followed up for more than 3 months. Demographic, clinical, and laboratory parameters were evaluated for their predictive value of relapse. Results After a median follow-up period of 12.2(4.8 - 21.2) months, 55.7% (59/106) patients experienced a relapse. The cumulative relapse rate was 39%, 48% and 61% at 6 months, 1 year and 2 years, respectively. Based on multivariable analysis, CD-related surgery before infusion (P = 0.013, hazard ratio (HR): 2.671, 95% confidential interval (CI): 1.230 - 5.798), step-up therapeutic regimen (P = 0.035, HR: 2.073, 95%CI: 1.054 - 4.080), low albumin (Alb) level at week 0 (P = 0.022, HR: 3.431, 95%CI: 1.196 - 9.846) and high C-reactive protein (CRP) level at week 30 (P = 0.007, HR: 2.643, 95%CI: 1.310 - 5.332) were associated with clinical relapse. Conclusions After cessation of scheduled IFX therapy in CD patients with clinical remission, nearly half of the patients experienced a relapse within 1 year. In the event of the presence of certain predictive factors, IFX scheduled therapy should probably be continued.

Abstract
BACKGROUND Biological tumor necrosis factor (TNF) inhibitors have revolutionized the treatment of inflammatory bowel disease and redefined treatment goals to include mucosal healing. Clinicians are faced with challenges such as inadequate responses, treatment failures, side effects, and high drug costs. The objective is to review optimization of anti-TNF therapy by use of personalized treatment strategies based on circulating drug levels and antidrug antibodies (Abs), i.e. therapeutic drug monitoring (TDM). Furthermore, to outline TDM-related pitfalls and their prevention. METHODS Literature review. RESULTS Circulating anti-TNF drug trough level is a marker for the pharmacokinetics (PK) of TNF inhibitors. Because of a number of factors, including antidrug antibodies, PK varies between and within patients across time leading to variable clinical outcomes. Differences in intestinal inflammatory phenotype influencing the pharmacodynamic (PD) responses to TNF inhibitors also affect treatment outcomes. As an alternative to handling anti-TNF-treated patients by empiric strategies, TDM identifies underlying PK and PD-related reasons for treatment failure and aids decision making to secure optimal clinical and economic outcomes. Although promising, evidence does not the support use of TDM to counteract treatment failure in quiescent disease. Use of TDM is challenged by methodological biases, difficulties related to differentiation between PK and PD problems, and temporal biases due to lack of chronology between changes in PK versus symptomatic and objective disease activity manifestations. Biases can be accommodated by knowledgeable interpretation of results obtained by validated assays with clinically established thresholds, and by repeated assessments over time using complimentary techniques. CONCLUSIONS TDM-guided anti-TNF therapy at treatment failure has been brought from bench to bedside.

Abstract
The medical management of Crohn's disease is a rapidly evolving field with expanding therapeutic drug options and treatment strategies. In addition to corticosteroids, immunomodulators, and anti-tumor necrosis (anti-TNF) agents, a new anti-adhesion medication (vedolizumab) has been approved. Individualized patient-based dosing of immunomodulators and biologic agents is now possible with therapeutic drug monitoring (TDM). There is a changing paradigm in treatment goals to achieve deeper remission identified by composite clinical and endoscopic endpoints. More aggressive treatment strategies in the postoperative setting have been proposed due to emerging data on medication efficacy in this setting. Management algorithms that stratify CD patients into risk groups to balance treatment benefit against adverse events and costs are being developed to translate research into clinical practice. This review provides an update on these new developments for practicing gastroenterologists.

Abstract
OBJECTIVES To perform a meta-analysis of the risk of relapse after discontinuation of anti-tumor necrosis factor (anti-TNF) therapy in patients with Crohn's disease (CD) and ulcerative colitis (UC), to evaluate risk factors for relapse, and to assess the response to retreatment with the same anti-TNF. METHODS Studies evaluating the incidence of relapse after anti-TNF discontinuation in patients with CD or UC who reached clinical remission with anti-TNFs were included. Bibliographies up to January 2015 were searched. Frequency of relapse after discontinuation of anti-TNF agents was determined; meta-analyses were performed using the inverse-variance method. RESULTS We included 27 studies (21 infliximab and 6 infliximab/adalimumab). The overall risk of relapse after discontinuation of anti-TNF therapy was 44% for CD (95% confidence interval (CI) 36-51%; I(2)=79%; 912 patients) and 38% for UC (23-52%; I(2)=82%; 266 patients). In CD, the relapse rate was 38% at 6 months after discontinuation (short term), 40% at 12 months (medium term), and 49% at >25 months (long term). In UC, 28% of patients relapsed at 12 months. In CD, when clinical remission was the only criterion for stopping anti-TNF therapy, the relapse rate after 1 year was 42%, which decreased to 26% when endoscopic remission was also required. Retreatment with the same anti-TNF induced remission again in 80% of cases (68-91%). CONCLUSIONS Approximately one-third of patients with inflammatory bowel disease in remission under anti-TNF treatment relapsed 1 year after discontinuation. This proportion increased to half in the long term. In CD patients, the risk of relapse was lower when the criterion for discontinuation was endoscopic remission and not only clinical remission. Response to retreatment with the same anti-TNF agent was favorable.

Abstract
An endoscopic examination is currently the most reliable method for monitoring disease activity in patients with inflammatory bowel disease (IBD). However, endoscopic evaluations are unable to detect mucosal inflammation at the earliest stages. The present study aimed to evaluate the molecular profiles of inflamed and unaffected colon mucosa from patients with mild Crohn's disease (CD) and ulcerative colitis (UC), in order to identify a more sensitive method for monitoring mucosal impairment. Patients were recruited and colon biopsies from the inflamed and the normal‑appearing mucosa of patients with mild IBD were obtained by colonoscopy. Gene expression analysis was performed using microarrays, after which Gene Ontology and clustering were performed using bioinformatics. In addition, the levels of inflammatory cytokines were analyzed by reverse transcription‑quantitative polymerase chain reaction. A total of 620 genes in the inflamed and 210 genes in the unaffected colon mucosa with at least a 3‑fold change, as compared with healthy controls, were detected in patients with mild CD, and 339 genes in the inflamed and 483 genes in the unaffected colon mucosa were detected in patients with mild UC. Heat mapping demonstrated a similarity in the gene alteration patterns, and altered transcripts overlapped, between the inflamed and unaffected colon mucosa. Interferon‑γ and interleukin‑17 mRNA levels were comparably elevated in the inflamed and unaffected colon mucosa from patients with IBD. Marked gene expression alterations were detected in the inflamed and unaffected colon mucosa from patients with mild IBD, and these showed marked similarity and overlap between the two groups. The results of the present study suggested that inflammation was not limited to the endoscopic lesions and that gene expression profiling may be considered a sensitive tool for monitoring mucosal inflammation, predicting relapses and optimizing therapeutic strategies for patients with IBD.

Abstract
Little is known on the natural history of Crohn's disease (CD) before diagnosis. By the time the patient is diagnosed, the disease has often produced considerable damage to the intestinal mucosa and sometimes other organs. Such period before diagnosis might involve both a silent and a symptomatic phase. The silent phase, or preclinical CD, might last several years after the biological disease onset. Evidence is accumulating that the symptomatic phase might also go undiagnosed for months or years. In fact, for each established case of CD, there are probably several undiagnosed cases, a classic iceberg phenomenon of disease. Such status quo--lagging behind diagnostic standards for many other diseases--effectively hampers efforts to block disease evolution and the development of complications. This is no longer tenable because CD is a debilitating, severe, and costly affection, whose incidence is rapidly rising worldwide. Here, we will review what is currently known on preclinical and undiagnosed CD and what could be done to improve accuracy and timeliness of diagnosis.

Abstract
Objective In patients with postoperative recurrence of Crohn’s disease endoscopic and clinical remission can be maintained for up to 1 year with low infliximab doses (3 mg/Kg). However, in theory low-dose infliximab treated patients could develop subtherapeutic trough levels, infiximab antibodies, and might loose response to therapy. To verify this hypothesis infliximab pharmacokinetics and clinical/endoscopic response were checked in a group of patients treated in the long term with low infliximab doses. Design Infliximab antibodies, infliximab levels, highly-sensitive CRP and fecal calprotectin were measured during the 8-week interval in 5 consecutive patients in clinical (Crohn’s Disease Activity Index < 150) and endoscopic (Rutgeerts scores 0–1) remission after one year of therapy with infliximab 3 mg/Kg. For comparison with reported standards, infliximab pharmacokinetics and inflammatory parameters were also tested in 6 Crohn’s disease patients who did not undergo surgery and who were in clinical remission while on infliximab 5 mg/Kg. Patients on low infliximab dose also underwent colonoscopy after 18 additional months of therapy. Results Highly sensitive CRP and fecal calprotectin increased in all patients during the 8-week interval. Infliximab trough levels were lower in patients treated with the low dose compared to controls (mean±SE: 2.0±0.3 vs 4.75±0.83 μg/mL respectively p<0.05). Infliximab antibodies were present in two of the subjects treated with low infliximab dose and in none of the controls. However, in low dose-treated patients after 18 additional months of therapy endoscopy continued to show mucosal remission and none of them developed clinical recurrence or side effects. Conclusions Patients treated with low infliximab doses had lower trough levels compared to patients treated with 5 mg/Kg and some developed antibodies to infliximab. However, low infliximab doses sustained clinical and endoscopic remission for a total of 30 months of treatment.

Gastroenterology 2015; 149:1716-30. [PMID: 26381892 DOI: 10.1053/j.gastro.2015.08.055] [Citation(s) in RCA: 156] [Impact Index Per Article: 17.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/29/2015] [Revised: 08/10/2015] [Accepted: 08/13/2015] [Indexed: 12/14/2022]
Abstract
Little is known about the optimal duration of therapy with an anti-tumor necrosis factor (TNF) agent and/or an immunomodulator for patients with inflammatory bowel disease (IBD). We performed a systematic search of the literature to identify studies reporting after de-escalation (drug cessation or dose reduction) of anti-TNF agents and/or immunomodulators in patients in remission from IBD. Studies were reviewed according to the type of IBD and drug. Rates of relapse, factors associated with relapse, and response to re-treatment were determined. Our search yielded 6315 unique citations; we analyzed findings from 69 studies (18 on de-escalation [drug cessation or dose reduction] of immunomodulator monotherapy, 8 on immunomodulator de-escalation from combination therapy, and 43 on de-escalation of anti-TNF agents, including 3 during pregnancy) comprising 4672 patients. Stopping immunomodulator monotherapy after a period of remission was associated with high rates of relapse in patients with Crohn's disease or ulcerative colitis (approximately 75% of patients experienced a relapse within 5 years after therapy was stopped). Most studies of patients with Crohn's disease who discontinued an immunomodulator after combination therapy found that rates of relapse did not differ from those of patients who continued taking the drug (55%-60% had disease relapse 24 months after they stopped taking the immunomodulator). The only study in patients with ulcerative colitis supported continued immunomodulator use. Approximately 50% of patients who discontinued anti-TNF agents after combination therapy maintained remission 24 months later, but the proportion in remission decreased with time. Markers of disease activity, poor prognostic factors, and complicated or relapsing disease course were associated with future relapse. In conclusion, based on a systematic review, 50% or more of patients with IBD who cease therapy have a disease relapse. Further studies are required to accurately identify subgroups of patients who are good candidates for discontinuation of treatment. The decision to withdraw a drug should be made for each individual based on patient preference, disease markers, consequences of relapse, safety, and cost.

Abstract
BACKGROUND The discontinuation of anti-tumour necrosis factor (anti-TNF) treatment in inflammatory bowel disease (IBD) patients in remission could be considered. AIM To evaluate the factors associated with relapse of IBD after discontinuation of anti-TNF therapy. METHODS Electronic (PubMed/Embase) and manual search up to January 2015. RESULTS The overall risk of relapse after discontinuation of anti-TNFs (27 studies) was 44% for Crohn's disease (CD; follow-up range: 6-125 months) and 38% for ulcerative colitis (follow-up range: 6-24 months). Several factors were investigated to identify patients who are more likely to achieve long-lasting remission after anti-TNF discontinuation. The factors associated with a higher risk of relapse are younger age, smoking, longer disease duration, and fistulising perianal CD. Laboratory markers such as low haemoglobin levels, high C-reactive protein levels and high faecal calprotectin seem to increase the risk of relapse. On the other hand, low serum anti-TNF levels seem to be associated with a lower risk of flare-up. Mucosal healing seems to decrease the risk of relapse after anti-TNF discontinuation (overall, this risk is 26% at 1 year with mucosal healing and 42% without), although this observation has not been confirmed by some authors. In patients receiving escalated anti-TNF doses or receiving anti-TNFs for the prevention of post-operative CD recurrence, the risk of relapse after discontinuation is high (>75%). Re-administration of the drug in those who relapsed after stopping treatment is effective and safe. CONCLUSIONS A high proportion of patients with IBD relapse after discontinuation of anti-TNF treatment. As available data are insufficient to make strong recommendations on when anti-TNF therapy could be stopped, decisions should be taken on an individual basis.

Abstract
BACKGROUND & AIMS There are limited data on the effects of discontinuing infliximab therapy for Crohn's disease (CD). We investigated the long-term outcome of patients with CD who discontinued infliximab while in clinical remission, and searched for prognostic markers of continued remission after infliximab cessation. METHODS We performed a retrospective, single-center study of 100 patients with CD who discontinued infliximab upon achieving clinical remission; 84 patients continued immunomodulator therapy. Clinical and endoscopic data were retrieved from a medical database in Belgium, and patients were followed up through April 2013 (median, 9.7 y; interquartile range, 8-11.5 y). Sustained clinical remission (SCR) was defined as maintenance of disease remission, without escalation in medical therapy or CD-related surgeries, until the end of the follow-up period. We measured trough concentrations of infliximab, antibodies to microbial antigens, and circulating inflammatory markers in serum samples collected before treatment and at the time of infliximab discontinuation. RESULTS At the end of the follow-up period, 52 patients had SCR. Univariate (log-rank) analysis associated SCR with patient age at diagnosis (≥25 y; P = .012) and disease duration (<1 y; P = .017). Among factors evaluated at the time of infliximab discontinuation, infliximab trough concentrations (<6 μg/mL; P = .031), complete mucosal healing (P = .046), and serum positivity for vascular cell adhesion molecule-1 (>0.67 μg/mL; P = .024) were associated with SCR. In multiple Cox proportional hazards regression analysis, only age at diagnosis of 25 years and older was associated independently with SCR (hazard ratio, 1.83; 95% confidence interval, 1.03-3.25; P = .04). CONCLUSIONS In a large, real-life study, 52% of patients with CD who discontinued infliximab upon achieving clinical remission remained in SCR after a median period of approximately 10 years; Most patients remained on immunomodulator therapy. Although patients with CD have variable responses to infliximab, a subgroup achieved long-term remission after infliximab discontinuation.

Abstract
Anti-tumour necrosis factor α (anti-TNFα) therapy is an established treatment in inflammatory bowel disease. However, this treatment is associated with high costs and the possibility of severe adverse events representing a true challenge for patients, clinicians and health care systems. Consequently, a crucial question is raised namely if therapy can be stopped once remission is achieved and if so, how and in whom. Additionally, in a real-life clinical setting, discontinuation may also be considered for other reasons such as the patient’s preference, pregnancy, social reasons as moving to countries or continents with less access, or different local policy or reimbursement. In contrast to initiation of anti-TNFα therapy guidelines regarding stopping of this treatment are missing. As a result, the decision of discontinuation is still a challenging aspect in the use of anti-TNFα therapy. Currently this is typically based on an estimated, case-by-case, benefit-risk ratio. This editorial is intended to provide an overview of recent data on this topic and shed light on the proposed drug withdrawal strategies.
