Optimizing biologic therapy in inflammatory bowel disease: a Delphi consensus in the United Arab Emirates. Therap Adv Gastroenterol 2021; 14:17562848211065329. [PMID: 34987611 PMCID: PMC8721421 DOI: 10.1177/17562848211065329] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/10/2021] [Accepted: 11/19/2021] [Indexed: 02/04/2023] Open
Abstract
BACKGROUND Inflammatory bowel diseases (IBD) are chronic, relapsing-remitting inflammatory conditions with a substantial negative impact on health-related quality of life and work productivity. Treatment of IBD has been revolutionized by the advent of biologic therapies, initially with anti-TNF agents and more recently with multiple alternatives targets, and yet more under development. OBJECTIVES Approximatively one third of patients do not respond to biologic therapy and more importantly a significant proportion experiences partial response or loss of response during treatment. The latter are common clinical situations and paradoxically are not addressed in the commercial drug labels and available guidelines. There is therefore a clinical need for physicians to understand when and how eventually to optimize the biologic therapy. DESIGN This consensus using a Delphi methodology was promoted and supported by the Emirates Society of Gastroenterology and Hepatology to close this gap. DATA SOURCES AND METHODS Following an extensive systematic review of over 60,000 studies, 81 studies with dose escalation and five addressing drug monitoring were selected and in addition five systematic reviews and three guidelines. RESULTS AND CONCLUSION after three rounds of voting 18 statements were selected with agreement ranging from of 80% to 100.

J Clin Med 2021; 10:2132. [PMID: 34069295 PMCID: PMC8156358 DOI: 10.3390/jcm10102132] [Citation(s) in RCA: 11] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/31/2021] [Revised: 05/07/2021] [Accepted: 05/07/2021] [Indexed: 02/06/2023] Open
Abstract
Loss of response to antitumor necrosis factor (anti-TNF) therapies in inflammatory bowel disease occurs in a high proportion of patients. Our aim was to evaluate the loss of response to anti-TNF therapy, considered as the need for dose intensification (DI), DI effectiveness and the possible variables influencing its requirements. Bibliographical searches were performed. SELECTION prospective and retrospective studies assessing DI in Crohn's disease and ulcerative colitis patients treated for at least 12 weeks with an anti-TNF drug. EXCLUSION CRITERIA studies using anti-TNF as a prophylaxis for the postoperative recurrence in Crohn's disease or those where DI was based on therapeutic drug monitoring. DATA SYNTHESIS effectiveness by intention-to-treat (random effects model). Data were stratified by medical condition (ulcerative colitis vs. Crohn's disease), anti-TNF drug and follow-up. RESULTS One hundred and seventy-three studies (33,241 patients) were included. Overall rate of the DI requirement after 12 months was 28% (95% CI 24-32, I2 = 96%, 41 studies) in naïve patients and 39% (95% CI 31-47, I2 = 86%, 18 studies) in non-naïve patients. The DI requirement rate was higher both in those with prior anti-TNF exposure (p = 0.01) and with ulcerative colitis (p = 0.02). The DI requirement rate in naïve patients after 36 months was 35% (95% CI 28-43%; I2 = 98%; 18 studies). The overall short-term response and remission rates of empirical DI in naïve patients were 63% (95% CI 48-78%; I2 = 99%; 32 studies) and 48% (95% CI: 39-58%; I2 = 92%; 25 studies), respectively. The loss of response to anti-TNF agents-and, consequently, DI-occurred frequently in inflammatory bowel disease (approximately in one-fourth at one year and in one-third at 3 years). Empirical DI was a relatively effective therapeutic option.

Abstract
BACKGROUND AND AIMS Epidemiological studies have established an association between psoriasis and inflammatory bowel disease [IBD], i.e. ulcerative colitis [UC] and Crohn's disease [CD], but results are inconsistent. The aim of this study was therefore to quantify the prevalences and association between IBD and psoriasis. METHODS PubMed, Web of Science, and EMBASE were searched from database inception through April 2018 for studies reporting data on psoriasis among patients with IBD and vice versa. Meta-analysis was performed to estimate, respectively, the prevalences and association between IBD and psoriasis. Data extraction was according to the PRISMA guideline, and quality assessment was made using the Newcastle-Ottawa Scale. The main outcomes were the proportion of psoriasis patients with IBD and vice versa, as well as the association (odds ratio [OR]) of IBD in psoriasis and psoriasis in IBD, respectively. RESULTS Based on quantitative analysis of 93 studies, the prevalence of psoriasis in CD and in UC was 3.6% (95% confidence interval [CI] 3.1%-4.6%) and 2.8% [95% CI 2.0%-3.8%] respectively. The prevalence of CD and UC was 0.7% [95% CI 0.2%-1.3%] and 0.5% [95% CI 0.3%-0.8%], respectively, among patients with psoriasis. Presence of CD or UC was significantly associated with psoriasis, with OR 2.0 [95% CI 1.4-2.9] and OR 1.5 [95% CI 1.2-2.0], respectively. Presence of psoriasis was significantly associated with CD: OR 2.2 [95% CI 1.6-3.1] and with UC: OR 1.6 [95% CI 1.3-2.0]. CONCLUSIONS We found significant bidirectional associations between psoriasis and IBD, warranting increased awareness among clinicians in the diagnostic process, especially in children and adolescents with IBD. Last, this study showed an increased frequency of paradoxical psoriasis in patients treated with biologics.

Clinical Benefit of Long-Term Adalimumab Treatment in Patients With Crohn's Disease Following Loss of Response or Intolerance to Infliximab: 96-Week Efficacy Data From GAIN/ADHERE Trials. J Crohns Colitis 2018; 12:930-938. [PMID: 29697818 PMCID: PMC6065484 DOI: 10.1093/ecco-jcc/jjy050] [Citation(s) in RCA: 13] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/15/2018] [Accepted: 05/21/2018] [Indexed: 12/16/2022]
Abstract
BACKGROUND AND AIMS In the 4-week GAIN clinical trial, adalimumab was efficacious in inducing remission in patients with moderate-to-severe Crohn's disease [CD] who had prior loss of response/intolerance to infliximab. The efficacy and safety of adalimumab in these patients are reported here for up to 96 weeks or for 3 years, respectively, in the ADHERE open-label extension study. METHODS Patients who completed GAIN could enrol in ADHERE and receive open-label adalimumab 40 mg every other week. Efficacy variables included clinical response (Crohn's Disease Activity Index [CDAI] decrease from baseline ≥70/≥100 points [CR-70/CR-100]) and remission [CDAI<150], steroid discontinuation and fistula remission [absence of drainage]. Data were reported using hybrid non-responder imputation [hNRI], last observation carried forward and as-observed analysis. Subgroup analyses were performed by randomized group in GAIN and by Week 4 efficacy in GAIN. Safety was also assessed. RESULTS A total of 310 patients from GAIN enrolled in ADHERE. CR-70, CR-100 and remission rates at Week 96 were 39.0%, 35.5%, and 26.5% [hNRI], respectively. Of the patients with CR-70 response or remission at Week 4 of GAIN, 45.5% and 44.4% [hNRI], respectively, maintained the effect at Week 96. Steroid discontinuation and steroid-free remission rates increased from Week 12 to 96 in patients using corticosteroids at GAIN baseline. CONCLUSIONS Long-term adalimumab maintenance therapy led to sustained clinical remission and response, and steroid discontinuation in a considerable proportion of patients with CD previously treated with infliximab. No new safety signals were observed in this patient population.

Abstract
Purpose This study aimed to evaluate the therapeutic value of adalimumab (ADA) for fistula in Crohn's disease (CD). Methods A computerized search of electronic databases, including PubMed, Web of Science, Embase, Google scholar, and the Cochrane Library from 2000 to October 2016, was performed. Randomized controlled trials (rcts) or nonrandomized controlled trials (n-rcts) were included in this article to evaluate the role of ADA in the management of fistula in CD. The methodological index for nonrandomized studies (MINORS evaluation tools) was used to assess the quality of every study. Result Overall, seven studies and 379 patients comforted to the inclusion criteria of this meta-analysis. The result showed that 36% (95% CI: 0.31–0.41) of patients with complete fistula closure and 31% (95% CI: 0.031–0.61) of patients with partial response were received in CD with ADA treatment. Conclusion We concluded that ADA is effective and safe for the treatment of fistula in CD according to current evidence.

Abstract
BACKGROUND AND AIMS Large-scale studies regarding the long-term outcomes of adalimumab (ADA) treatment in Asian patients with Crohn's disease (CD) are still scarce. METHODS We retrospectively analyzed the long-term outcomes of ADA treatment in Korean CD patients who commenced on scheduled ADA treatment at Asan Medical Center between November 2008 and July 2016. Clinical response was defined as maintaining ADA treatment without dose intensification (DI) and/or major abdominal surgery (MAS). RESULTS Of the 254 patients who received at least two doses of ADA at 2-week intervals as induction therapy, 250 patients (98.4%) showed an initial favorable response by week 4. Among responders, 243 patients were followed up for longer than 4 weeks and were included for further analysis. The median duration of ADA maintenance therapy was 19.4 months. At the last follow-up, 45 patients (18.5%) required DI after a median of 16.8 months and 31 (12.8%) required MAS after a median of 8.9 months. Finally, 161 patients (66.3%) were still receiving ADA without DI and/or MAS. The cumulative probability of maintaining ADA without DI and/or MAS was 81.1% at 1 year, and 36.5% at 5 years. Secondary loss of response to previous infliximab (P = 0.001) and elevated baseline C-reactive protein at starting ADA treatment (P = 0.008) were identified as independent predictors of a poor response to ADA treatment using multivariate regression analysis. CONCLUSIONS The long-term outcome of ADA treatment in a real-life cohort of Korean patients with CD appears to be comparable to that reported in previously published Western studies.

Abstract
BACKGROUND Biologics used to treat Crohn's disease (CD) may lose their effect over time, requiring dose escalation. Little information is available on this topic. AIM To summarize rates of dose escalation, duration, de-escalation in observational studies of CD in adults treated with adalimumab, infliximab, and vedolizumab in Europe. METHODS Two independent investigators searched Medline and Embase for observational studies published in 1998-2015 and proceedings from four major scientific meetings. Rates were summarized descriptively. RESULTS In total, 58 articles from 12 European countries were analyzed (49 full articles, nine abstracts), providing 65 reports with 7,850 patients; 35 reported on 3,830 patients with adalimumab (ADA), and 30 on 4,020 patients with infliximab (IFX). Overall, 29.9% ± 3.5% of patients required dose escalation; 32.8% ± 6.2% with ADA and 25.2% ± 2.4% with IFX (p = .35 between drugs). Rates increased according to line of treatment: 19% for first line, 37% second, and 41% third. The median time to loss of response was 12 months, and the weighted average was 15.1 ± 5.9 months. Median time to escalation was 6.7 months; 6.7 months for ADA and 7.5 for IFX (p = .86). Short-term response rates to escalation were 63% for ADA and 45% for IFX (p = .08). There were no papers available for vedolizumab. CONCLUSIONS A substantial proportion of patients receiving ADA or IFX for Crohn's disease require dose escalation after a short period of time.

Abstract
BACKGROUND To review the frequency with which anti-TNF-α loses its effect and dose "intensification" is required for Crohn's disease (CD) treatment. METHODS Electronic databases were searched for eligible studies. Raw data from studies meeting inclusion criteria were pooled for effect estimates. Subgroup analyses were performed for exploration of heterogeneity regarding all outcomes. RESULTS Eighty-six eligible studies were included. Estimates of loss of response (LOR) incidence ranged from 8 to 71%. The random effects pooled incidence of LOR with a median follow-up of 1-year was 33% (95% CI 29-38, 55 studies, n = 6135). The effect estimate based on data from patients with infliximab was 33% (95% CI 27-40), 30% (95% CI 22-39) for adalimumab, and 41% (95% CI 30-53) for certolizumabpegol. Overall, the mean percentage of patients' LOR to anti-TNFs was 38.5%. The annual risk for LOR was 20.9% per patient-year. The random-effects pooled rate of need for dose intensification with a median follow-up of 1 year was 34% (95% CI 28-41, 38 studies, n = 10,690). The effect estimate for infliximab was 38% (95% CI 28-50), 36% (95% CI 30-43) for adalimumab, and 2% (95% CI 2-3) for certolizumab-pegol. The mean percentage of patients who needed an anti-TNF dose escalation was 23% with an annual risk of 18.5% per patient-year. There was no evidence of publication bias for incidence of LOR but not for the dose intensification (p = 0.001). CONCLUSIONS Overall, around one-third of CD patients experience a LOR and required dose intensification in primary anti-TNF-α responders.

Abstract
BACKGROUND Adalimumab (ADA) is an effective treatment for Crohn's disease (CD). In rheumatology, sex differences concerning the response to ADA therapy have been described. However, such differences have not yet been reported for patients with CD. As such, the aim of this study was to compare ADA treatment outcomes in male and female patients with CD. METHODS A clinical cohort was formed of consecutive patients with CD starting ADA in a single tertiary center between March 2006 and February 2011. The cohort was followed up to August 2015. Clinical outcomes were primary nonresponse, secondary nonresponse, and drug survival (ongoing ADA use). Reasons for stopping ADA were recorded. Kaplan-Meier analysis and Cox regression were used to assess drug survival. RESULTS The cohort consisted of 107 female and 81 male patients. Median follow-up was 6.0 years (range 0.3-9.2). Drug survival was higher in male than female patients (48.1% versus 30.8%, P = 0.016). Side effects were reported more often by female patients (81.3% versus 64.2%, P = 0.008), and female patients ceased ADA more often due to side effects (35.4% versus 18.4%, P = 0.017). In survival analysis, female sex was associated with higher cessation rates (P = 0.006). Cox regression also identified female sex (P = 0.020), along with higher baseline CD Activity Index (P = 0.003), as predictors of ADA cessation. CONCLUSIONS Female sex is negatively associated with ADA drug survival. Female patients report more side effects and cease ADA because of side effects more often. A more personalized and sex-specific approach seems warranted to increase drug survival in female patients.

Treatment of perianal fistula in Crohn's disease: a systematic review and meta-analysis comparing seton drainage and anti-tumour necrosis factor treatment. Colorectal Dis 2016; 18:667-75. [PMID: 26921847 DOI: 10.1111/codi.13311] [Citation(s) in RCA: 67] [Impact Index Per Article: 8.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/01/2015] [Accepted: 11/18/2015] [Indexed: 12/13/2022]
Abstract
AIM The introduction of anti-tumour necrosis factor (anti-TNF; infliximab and adalimumab) has changed the management of Crohn's perianal fistula from almost exclusively surgical treatment to one with a much larger emphasis on medical therapy. The aim of this systematic review was to provide an overview of the success rates of setons and anti-TNF for Crohn's perianal fistula. METHOD Studies evaluating the effect of setons and anti-TNF on Crohn's perianal fistula were included. Studies assessing perianal fistula in children, rectovaginal and rectourinary fistulae were excluded. The primary end-point was the fistula closure rate. Partial closure and recurrence rates were secondary end-points. RESULTS Ten studies on seton drainage were included (n = 305). Complete closure varied from 13.6% to 100% and recurrence from 0% to 83.3%. In 34 anti-TNF studies (n = 1449), complete closure varied from 16.7% and 93% (partial closure 8.0-91.2%) and recurrence from 8.0% to 40.9%. Four randomized controlled trials (n = 1028) comparing anti-TNF with placebo showed no significant difference in complete or partial closure in meta-analysis (risk difference 0.12, 95% CI -0.06 to 0.30 and 0.09, 95% CI -0.23 to 0.41, respectively). Subgroup analysis (n = 241) showed a significant advantage for complete fistula closure with anti-TNF in two trials with follow-up > 4 weeks (46% vs 13%, P = 0.003 and 30% vs 13%, P = 0.03). Of four included cohort studies, two revealed a significant difference in response in favour of combined treatment (P = 0.001 and P = 0.014). CONCLUSION Closure and recurrence rates after seton drainage as well as anti-TNF vary widely. Despite a large number of studies, no conclusions can be drawn regarding the preferred strategy. However, combination therapy with (temporary) seton drainage, immunomodulators and anti-TNF may be beneficial in achieving perianal fistula closure.

Effectiveness of anti-TNFα drugs in patients with Crohn's disease who do not achieve remission with their first anti-TNFα agent. Dig Liver Dis 2016; 48:613-9. [PMID: 26992847 DOI: 10.1016/j.dld.2016.02.012] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/27/2015] [Revised: 02/13/2016] [Accepted: 02/22/2016] [Indexed: 12/11/2022]
Abstract
BACKGROUND Anti-TNF treatment is effective for Crohn's disease (CD); however, some patients did not achieve remission with these drugs. AIMS To evaluate the short-term effectiveness of a second anti-TNF in CD patients who did not achieve remission with the first one and to assess its durability. METHODS Patients who did not achieve remission with their first anti-TNF were included. The short-term response of the second anti-TNF was assessed, the long-term response was evaluated in patients who achieved remission (Kaplan-Meier). Cox-regression was performed to identify predictors of loss of efficacy. RESULTS In all, 118 CD patients received a second anti-TNF after primary failure of the first. The first anti-TNF was discontinued because of non-response in 54% of patients and partial response in 46%. Fifty-one percent of patients achieved remission in the short-term. The probability of remission was lower in patients for whom the drug indication was perianal disease (OR=0.3, 95% CI=0.1-0.7, P=0.005). The dose was increased in 33% of patients, and 37% achieved/regained remission. The probability of maintaining remission was 76%, 68% and 64% at 12, 18 and 24 months, respectively. CONCLUSIONS Approximately half of the patients achieved remission with a second anti-TNF after primary failure of the first, this strategy was less effective in patients with perianal disease.

Abstract
Anti-tumour necrosis factor (TNF)-α therapy has revolutionized inflammatory bowel disease (IBD) treatment. Infliximab and adalimumab either as monotherapy or in combination with an immunomodulator are able to induce clinical and biological remission in patients with moderate and severe Crohn’s disease (CD) and ulcerative colitis (UC). These new therapies have led to a shift in the goals of IBD management from just controlling clinical symptoms to preventing disease progression. However, despite these advances in medical therapy, surgery is still required in 30%-40% of patients with CD and 20%-30% of patients with UC at some point during their lifetime. While biologics certainly play a major role in the medical treatment of IBD, there is concern about the effects of these anti-TNF-α agents on postoperative complications and morbidity. The purpose of this article is to review the role of surgery in the treatment of IBD in the age of biologics and the impact of these medications on per-operative outcomes. In this manuscript we review the relationship between biologic agents and surgery in the treatment of IBD. We also discuss in detail the periopetative risks and complications.

Abstract
BACKGROUND Nonresponse and loss of response to anti-TNF therapies in Crohn's disease represent significant clinical problems for which clear management guidelines are lacking. AIM To review the incidence, mechanisms and predictors of primary nonresponse and secondary loss of response to formulate practical clinical algorithms to guide management. METHODS Through a systematic literature review, 503 articles were identified which fit the inclusion criteria. RESULTS Primary nonresponse to anti-TNF treatment affects 13-40% of patients. Secondary loss of response to anti-TNF occurs in 23-46% of patients when determined according to dose intensification, and 5-13% of patients when gauged by drug discontinuation rates. Recent evidence suggests that the mechanisms underlying primary nonresponse and secondary loss of response are multifactorial and include disease characteristics (phenotype, location, severity); drug (pharmacokinetic, pharmacodynamic or immunogenicity) and treatment strategy (dosing regimen) related factors. Clinical algorithms that employ therapeutic drug monitoring (using anti-TNF tough levels and anti-drug antibody levels) may be used to determine the underlying cause of primary nonresponse and secondary loss of response respectively and guide clinicians as to which patients are most likely to respond to anti-TNF therapy and help optimise drug therapy for those who are losing response to anti-TNF therapy. CONCLUSIONS Nonresponse or loss of response to anti-TNF occurs commonly in Crohn's disease. Clinical algorithms utilising therapeutic drug monitoring may establish the mechanisms for treatment failure and help guide the subsequent therapeutic approach.

Abstract
BACKGROUND One-third of patients with Crohn's disease (CD) or ulcerative colitis (UC) receiving anti-TNFs do not respond to treatment, and a relevant proportion experience loss of response or intolerance. AIM To investigate the efficacy and safety of a second anti-TNF agent after primary/secondary failure or intolerance to a first drug. INCLUSION CRITERIA studies evaluating the efficacy of infliximab (IFX), adalimumab (ADA) and certolizumab-pegol (CZP) as the second anti-TNF in CD or UC. SEARCH STRATEGY Bibliographical searches (PubMed/Embase). DATA SYNTHESIS percentage of response/remission; the meta-analysis was performed using the inverse variance method. RESULTS We included 46 studies (37 CD, 8 UC, 1 pouchitis). The CD studies comprised 32 switching IFX→ADA, 4 IFX→CZP and 1 ADA→IFX. Overall, the second anti-TNF after the failure of IFX in CD induced remission in 43% and response in 63% of patients. The remission rate was higher when the reason to withdraw the first anti-TNF was intolerance (61%) than after secondary (45%) or primary failure (30%); response rates were, respectively, 72%, 62% and 53%. All UC studies switched IFX→ADA, six of them reporting remission rates ranging from 0% to 50%. Adverse events rate ranged from 0% to 81% in CD, most of them mild (serious adverse event 0-21%, discontinuation rate <20%). CONCLUSIONS The efficacy of a second anti-TNF in CD patients largely depends on the cause for switching. The remission rate is higher when the reason to withdraw the first anti-TNF is intolerance (61%), compared with secondary (45%) or primary failure (30%). Further studies of switch ADA→IFX are needed to evaluate this strategy. PROSPERO-registry-number: CRD42014012943.

Abstract
BACKGROUND The efficacy of adalimumab in maintaining remission in Crohn's disease patients may wane over time, leading to secondary loss of response that is often managed with dose escalation. However, the response to adalimumab dose escalation and long-term outcomes after escalation have not been well evaluated. AIMS To characterise the short- and long-term clinical responses to adalimumab dose escalation for secondary loss of response. METHODS A retrospective cohort study evaluating Crohn's disease out-patients requiring adalimumab dose escalation for secondary loss of response from 2003 to 2013 was conducted. The primary outcome was the proportion of patients achieving symptomatic clinical response to dose escalation and subsequent development of tertiary loss of response. Duration of regained response was assessed by Kaplan-Meier analysis. RESULTS Ninety-two CD patients met inclusion criteria with mean duration of follow-up of 170.2 weeks (±129.6 weeks). Disease distribution was predominantly ileal (37/92, 40.2%) or ileocolonic (43/92, 46.7%), with equal distribution of inflammatory (34.8%), stricturing (27.2%), and penetrating (38.0%) disease phenotypes. At 24 weeks post-dose escalation, 74/92 (80.4%) patients had symptomatic clinical response. Among responders, median duration of sustained response was 69.2 weeks (IQR 29.4-107.1) but 42/74 (56.8%) responders experienced subsequent tertiary loss of response at a median time of 47.9 weeks (IQR 24.7-80.3). C-reactive protein >10.0 mg/L at the time of dose escalation predicted tertiary loss of response in univariate analysis (OR 3.32, 95% CI: 1.18-9.37). CONCLUSIONS In patients with Crohn's disease, adalimumab dose escalation is effective for recapturing symptomatic response after secondary loss of response, but more than half will eventually experience a tertiary loss of response.

Abstract
BACKGROUND AND AIMS Adalimumab is an effective therapy for induction and maintenance of Crohn's disease. However, results in clinical trials don't necessarily reflect daily clinical practice. Therefore, we assessed real-life long-term clinical response to adalimumab in a large population-based cohort and identified clinical parameters affecting response METHODS All consecutive patients in North-Holland that started adalimumab between 2003 and 2011 were included, of which medical charts were reviewed. Response to induction therapy was assessed after 3months. Sustained benefit of maintenance therapy was calculated from Kaplan-Meier survival tables depicting ongoing adalimumab treatment. Regression analyses were performed to identify factors predicting response to adalimumab therapy. RESULTS In total 438 Crohn's patients started adalimumab with 92.5% response to the induction phase. After 1year 83.3% showed sustained benefit of maintenance treatment, followed by 74.0% after 2years. Nevertheless, one third of patients were in steroid-free remission at the end of their follow-up. Response to induction was negatively affected by longer disease duration (OR 1.05; p<0.01) and strictures (OR 3.73; p=0.04). Increased CRP levels predicted higher rates of initial response (OR 0.31; p<0.01). Concomitant thiopurines in the first 6months of adalimumab treatment decreased the risk to fail maintenance therapy (HR 0.69, p=0.05). Previous infliximab therapy did not affect response to adalimumab, however dose escalation was more often deemed necessary (p<0.01). CONCLUSION Adalimumab was successful in the majority of patients, with 10% loss of response per subsequent year. Concomitant thiopurines might improve adalimumab maintenance treatment.

Abstract
BACKGROUND Switches between anti-tumor necrosis factor agents in the treatment of Crohn's disease (CD) occur in case of treatment failure, intolerance, or patient preference. No data are currently available on the usefulness of a second infliximab treatment after earlier discontinuation and previous switch to an alternative anti-tumor necrosis factor agent. In this study, we evaluated the clinical benefit of infliximab retreatment in patients with CD after sequential use of both infliximab and adalimumab. METHODS Twenty-nine patients with CD who had received earlier treatments with sequential infliximab and adalimumab and were then restarted on infliximab were retrieved from a multicenter registry designed for the follow-up of adalimumab treatment for CD. Short-term and sustained effects of infliximab retreatment were evaluated retrospectively by reviewing clinical records. Follow-up was 18 months for all patients. RESULTS In 13/29 (45%) patients, infliximab was reintroduced at intensified dosing schedule (>5 mg/kg or <8 wk) for 23/29 (79%) of patients similar to the schedule who were on at time of previous discontinuation. During the second infliximab treatment course, dosing was further intensified in 11 out of 29 (38%) patients. After 18 months 18/29 (62%), patients were still on continued therapy of their second infliximab treatment. Infliximab was discontinued (after a median of 7 mo) in 11 out of 29 patients for loss of response (n = 7 [24%]), intolerance (n = 3 [10%]), or non-compliance (n = 1 [3%]). Use of induction schedule or concomitant immunomodulators were not significantly associated with treatment benefit. CONCLUSIONS The majority of patients with CD benefit from a second treatment with infliximab after previous treatment with infliximab and adalimumab, which offer a meaningful therapeutic option in often highly refractory patients.

Abstract
AIM: To evaluate the effectiveness of infliximab as a second-line therapy in Crohn’s disease patients after adalimumab failure.
METHODS: A historical cohort study in a community-based gastroenterology practice evaluated Crohn’s disease patients treated with infliximab (induction plus maintenance) after adalimumab failure. Patients were identified using a large Spanish database (ENEIDA).
RESULTS: We included 15 Crohn’s disease patients who received infliximab after adalimumab failure. Five patients discontinued adalimumab due to loss of response, 3 due to adverse events and 7 due to partial response. After infliximab therapy was started, all patients who had interrupted adalimumab due to loss of efficacy regained response. All patients who discontinued adalimumab due to adverse events responded to infliximab and maintained this response; one of these patients had an uneventful course on infliximab, but 2 developed adverse events. None of the 7 patients who interrupted adalimumab due to partial response reached remission with infliximab.
CONCLUSION: Switching from adalimumab to infliximab may be useful in patients who develop adverse effects or loss of response, however, the benefit of infliximab in primary nonresponders was not established.

Abstract
Adalimumab is a subcutaneously administered, fully humanized anti-TNF-α monoclonal IgG1 antibody and represents an important new therapeutic option for the treatment of Crohn's disease for its convenient mode of administration and less adverse events. Adalimumab is effective in inducing and maintaining clinical response and remission in patients with moderate to severe Crohn's disease, which permits to spare potential steroid usage, achieve mucosal healing and improve the quality of life in these patients. Adalimumab has also been shown to be beneficial to patients who lose response or are intolerant to infliximab and to promote the closure of the fistula orifice. This article reviews the recent advances in the treatment of Crohn's disease with adalimumab.

Abstract
BACKGROUND Adalimumab is an effective treatment for Crohn's disease (CD), but may also be associated with loss of response. Few reports provide insight into the durability of treatment of CD with adalimumab for periods longer than 12 months in clinical practice. AIMS To evaluate the long-term durability of adalimumab maintenance treatment and to identify predictive factors associated with loss of response. METHODS CD patients who initially responded to adalimumab were evaluated in a historical cohort study. Maintenance of long-term response was estimated using Kaplan-Meier analysis. Cox regression analysis was performed to identify potential predictive factors for loss of efficacy. RESULTS In all, 380 CD patients were included (mean age, 38 years; 52% female). Of these, 43% had ileocolic CD, 50% inflammatory CD, and 41% perianal CD. Median follow-up with adalimumab was 8 months (range, 4-75 months). The annual risk of loss of response to adalimumab was 18% per patient-year of follow-up. Twenty-eight percent of patients were anti-TNF-naïve and 72% anti-TNF-experienced. The loss of efficacy was 8% per patient-year of follow-up in the anti-TNF-naïve patients and 22% in the anti-TNF-experienced group (P < 0.01). In the multivariate analysis, the presence of extraintestinal manifestations (hazard ratio [HR] = 1.7; 95% confidence interval [CI] = 1.02-2.9) and previous experience with other anti-TNF agents (HR = 2.5,95% CI = 1.2-5.3) were associated with higher risk of loss of efficacy. CONCLUSIONS A relevant proportion of CD patients on long-term adalimumab lost response. The risk of loss of response was higher (more than 2-fold) in anti-TNF-experienced than in anti-TNF-naïve patients (22% vs. 8% per patient-year of treatment). Having extraintestinal manifestations seems to increase the risk of loss of efficacy.

Abstract
BACKGROUND Adalimumab is effective for the induction and maintenance of remission in Crohn's disease (CD)-patients. AIM To find predictors for adalimumab dose escalation at initiation of adalimumab. METHODS Crohn's disease patients in a single tertiary referral centre who started adalimumab between July 2007 and March 2010 at an induction dose (week 0 160 mg subcutaneously (sc), week 2 80 mg sc) and maintenance dose of 40 mg sc thereafter every other week were followed prospectively. Patients on adalimumab for at least 3 months were included. The number of patients needing dose escalation was assessed. Patients that needed dose escalation were compared with patients that did not need dose escalation. RESULTS Of 199 CD patients treated with adalimumab and followed prospectively, 122 patients (M/F 54/68, median age 35 years, range 18-66 years, median CDAI 164, range 6-468) were treated for 3 months. In total 38% of these patients (46/122) needed a dose escalation within a median time of 21 weeks after adalimumab introduction (range 4-105). Body mass index (BMI) (P < 0.03) and secondary non-response to infliximab (IFX) (P < 0.06) were identified as predictors for dose escalation. Concomitant use of immunomodulators at initiation of adalimumab and the presence of autoantibodies to IFX did not predict dose escalation. CONCLUSIONS Over one-third adalimumab-treated patients are dose escalated within a median of 5 months. Higher BMI and secondary non-response to IFX treatment are predictive for a dose escalation during adalimumab treatment.

Abstract
Anti-tumor necrosis factor (TNF) therapy to treat inflammatory bowel disease has been available for more than a decade. Although extensive data on the outcome of anti-TNF therapy from individual clinical trials and patient cohorts are available, integrated guidance on the best use of such therapy to achieve optimal clinical outcomes when managing patients with luminal Crohn's disease is lacking. This review combines published data to establish practical strategies for anti-TNF therapy with respect to effective and safe timing of introduction, use of concurrent immunosuppressive therapy, dose escalation, managing relapse, changing drugs, pregnancy and breast feeding, and stopping drug treatment.

Abstract
BACKGROUND Adalimumab is a fully human monoclonal antibody targeting tumour necrosis factor with proven efficacy in the treatment of Crohn's disease (CD). AIM To investigate the predictors of medium-term clinical efficacy and mucosal healing during adalimumab therapy, in patients with CD, in specialised centres approved for biological therapy in Hungary. METHODS Data capture of the 201 CD patients was standardised and prospective (male/female: 112/89, median age: 33.0 years, duration: 8 years). Previous infliximab therapy had been administered in 48% of patients, concomitant steroids in 41%, azathioprine in 69% and combined therapy in 27% of patients. RESULTS Overall clinical response and remission rates at 24 weeks were 78% and 52%, respectively; at 52 weeks were 69% and 44%, respectively. Endoscopic improvement and healing were achieved in 43% and 24% of patients. In a logistic regression model, clinical efficacy and CRP at week 12, need for combined immunosuppression at induction, shorter disease duration and smoking were identified as independent predictors for 12-month clinical outcome, whereas CRP at week 12, clinical remission at week 24, inflammatory parameters and nonsmoking were associated to endoscopic improvement/healing. Intensification to weekly dosing was needed in 16% of patients. Parallel azathioprine therapy and clinical remission at week 12 were inversely associated with dose escalation. CONCLUSIONS Clinical efficacy and normalised CRP at week 12 (early deep clinical remission) are associated with medium-term clinical efficacy and mucosal healing during adalimumab therapy, whereas need for combined immunosuppression at induction and smoking status are predictors for non-response. Parallel azathioprine therapy may decrease the probability for dose escalation.

Abstract
BACKGROUND AND AIMS Non-response, loss of response, or intolerance to anti-tumour necrosis factor alpha (anti-TNFα) therapy is well recognised in Crohn's disease (CD) patients. Data concerning outcomes following the use of a second anti-TNFα therapy, particularly in patients who do not respond to a first anti-TNFα agent, are still emerging. The aim of this study was to assess response and tolerability to adalimumab following infliximab failure in a single centre cohort of CD patients. METHODS Data were collected prospectively on 44 patients who received adalimumab therapy following infliximab failure. Initial response to adalimumab therapy at 6weeks following induction was defined using a two point decrease in the Harvey-Bradshaw Index, with remission at this point defined using a Harvey Bradshaw index≤4. Sustained clinical benefit at the last point of follow up was determined using a physician's global assessment. Corticosteroid-free sustained clinical benefit was also assessed at this point. RESULTS Thirty-four (77%) patients had initial response to adalimumab therapy, with 28 (64%) having sustained clinical benefit. Corticosteroid-free sustained clinical benefit was achieved in nine (53%) of 17 patients requiring steroids at commencement of adalimumab. Four (44%) of the 9 patients who were primary non-responders to infliximab responded to adalimumab. The majority of CD patients who failed adalimumab therapy required surgery. CONCLUSIONS Second-line anti-TNFα therapy with adalimumab is effective at both inducing remission and maintaining response in CD patients who have failed infliximab, regardless of the reason for infliximab failure.

Abstract
OBJECTIVES The advent of biological therapies for inflammatory bowel disease (IBD) began in 1998 with the approval of infliximab for the treatment of refractory (to conventional agents) Crohn's disease (CD). Since then, the indications for anti-tumor necrosis factor-α (anti-TNFα) therapy have increased to include induction and maintenance of clinical responses and remissions for luminal and fistulizing CD, the treatment of children with CD, and the treatment of adults with ulcerative colitis. Additional utilities of biological therapies have included demonstrable mucosal healing, improvement in quality of life, reduction in surgeries and hospitalizations, and the treatment of extraintestinal manifestations of IBD including central and peripheral arthritis and pyoderma gangrenosum. Natalizumab has also been approved for the treatment of refractory Crohn's in patients who have failed conventional agents and anti-TNFα therapies. Unfortunately, despite the overall effectiveness of biological agents in a spectrum of indications for IBD, a significant proportion of patients do not respond or lose response over time. In this review, we intend to appraise the latest evolution in treatment strategies in IBD and to suggest an evidence-based approach and risk stratification while coping with cases of non-responders or loss of response to biological therapies. METHODS We conducted a literature search of English publications listed in the electronic databases of MEDLINE (source PUBMED) and constructed an analytical review based on definitions of response and loss of response, considering potential responsible mechanisms, clinical assessment tools, and finally recommending a practical approach for its prevention and management. RESULTS Favorable clinical outcome appears to be the consequence of sustained therapeutic drug levels, and the current literature supports a practice of dose adjustments. When immunogenicity develops to a single biological agent, response can be regained by introduction of an alternative biological agent of the same or different class. Efficacy is reduced with second-line agents either within or across classes compared with naive patients. In the absence of direct measurement of drug levels and anti-drug antibodies, clinical judgment is necessary to assess the mechanisms of loss of response, and more empiric decision making may be necessary to determine the choice of second-line biological agents. Optimal treatment strategies are still controversial. CONCLUSIONS It is essential to recognize the spectrum of mechanisms affecting response and loss of response to form a logical and efficient management algorithm, and, perhaps, it is time to incorporate the measurement of trough levels and anti-drug antibodies in the strategy of such an assessment. Prospective controlled trials are direly needed to investigate the optimal tailored management in individual patients who lose response.

Abstract
The objective of this study was to review loss of response and need for adalimumab dose intensification in adult and pediatric patients with Crohn's disease. Studies were identified through the electronic databases of MEDLINE and the annual meetings of Digestive Disease Week, of the United European Gastroenterology Week, and of the American College of Gastroenterology and the European Crohn's and Colitis Organization meetings. Studies evaluating loss of efficacy and/or need for dose intensification were included. Thirty-nine studies were included. The mean percentage of loss of response to adalimumab among primary responders was 18.2% and the annual risk was 20.3% per patient-year. The mean percentage of patients who required dose intensification among primary responders to adalimumab was 37% and the annual risk was 24.8% per patient-year. When considering initial responders and patients with primary non-response, the mean percentage of patients who needed an adalimumab dose escalation was 21.4% and the annual risk was 24.4% per patient-year. Pooled analysis showed that dose escalation permitted response to be regained in 71.4% and remission in 39.9% of patients. Predictors for loss of response or dose escalation were male gender, current/former smoker status, family history of inflammatory bowel disease, isolated colonic disease, extra-intestinal manifestations, 80/40 mg induction therapy, longer disease duration, greater baseline Crohn's Disease Activity Index, concomitant corticosteroid use, no deep remission at week 12, low serum trough concentrations of adalimumab, previous infliximab non-response and being previously treated with an anti-tumor necrosis factor agent. Overall, around one fifth of adult patients require dose intensification and experience a loss of response after initiation of adalimumab therapy. Adalimumab dose escalation permits response to be regained in the majority of patients.

Abstract
OBJECTIVES Whether all Crohn's disease (CD) patients should maintain long-term azathioprine treatment in combination with infliximab remains controversial. We analyzed the predictive factors of infliximab failure after azathioprine withdrawal. METHODS This was an observational study from a single referral center. All patients with luminal CD in remission who stopped azathioprine after receiving infliximab in combination with azathioprine for at least 6 months were studied. Cumulative probabilities of infliximab failure-free survival were estimated by the Kaplan-Meier method from the date of azathioprine withdrawal to the date of infliximab failure or last known follow-up. Infliximab failure was defined by: (i) disease flare requiring shortening of the dosing interval or increasing the infliximab dose to 10 mg/kg, or switching to adalimumab; (ii) acute or delayed hypersensitivity reactions leading to infliximab discontinuation; or (iii) CD-related surgery. RESULTS At last known follow-up, 35 out of 48 (73%) patients were infliximab failure free. The survival probabilities were 85% (+/-5%) at 12 months and 41% (+/-18%) at both 24 and 32 months. Cox proportional-hazards regression identified three predictors of infliximab failure: infliximab-azathioprine exposure duration of < or = 811 days (hazard ratio (HR)=7.46, P=0.01), C-reactive protein > 5 mg/l (HR=4.79, P=0.008), and platelet count > 298 10(9)/l (HR=4.75, P=0.02). CONCLUSIONS In CD in clinical remission under azathioprine-infliximab combination therapy, azathioprine withdrawal is associated with a high risk of relapse in patients with a duration of combination therapy of < 27 months and/or the presence of biological inflammation.

Abstract
Background Infliximab is usually administered by two monthly intravenous (iv) infusions, therefore requiring visits to hospital. Adalimumab is administered by self subcutaneous (sc) injections every other week. Both of these anti-TNF drugs appear to be equally efficacious in the treatment of Crohn's Disease and therefore the decision regarding which drug to choose will depend to some extent on patient choice, which may be based on the mode of administration. The aims of this study were to compare preferences in Inflammatory Bowel Disease (IBD) patients for two currently available anti-TNF agents and the reasons for their choices. Methods An anonymous questionnaire was distributed to IBD patients who had attended the Gastroenterology service (Ulster Hospital, Dundonald, Belfast, N. Ireland. UK) between January 2007 and December 2007. The patients were asked in a hypothetical situation if the following administering methods of anti-TNF drugs (intravenous or subcutaneous) were available, which drug route of administration would they choose. Results One hundred and twenty-five patients fulfilled the inclusion criteria and were issued questionnaires, of these 78 questionnaires were returned (62 percent response). The mean age of respondent was 44 years. Of the total number of respondents, 33 patients (42 percent) preferred infliximab and 19 patients (24 percent) preferred adalimumab (p = 0.07). Twenty-six patients (33 percent) did not indicate a preference for either biological therapy and were not included in the final analysis. The commonest reason cited for those who chose infliximab (iv) was: "I do not like the idea of self-injecting," (67 percent). For those patients who preferred adalimumab (sc) the commonest reason cited was: "I prefer the convenience of injecting at home," (79 percent). Of those patients who had previously been treated with an anti-TNF therapy (n = 10, all infliximab) six patients stated that they would prefer infliximab if given the choice in the future (p = 0.75). Conclusions There was a trend towards patient preference for infliximab (iv) treatment as opposed to adalimumab (sc) in patients with IBD. This difference may be due to the frequency of administration, mode of administration or differing 'times in the market-place', as infliximab had been approved for a longer period of time in Crohn's disease. Further studies are required in IBD patients to investigate whether patient choice will affect compliance, patient satisfaction and efficacy of treatment with anti-TNF therapies.

Abstract
BACKGROUND Therapy with adalimumab has been shown to be effective in Crohn's disease (CD) patients who have lost response or are intolerant to infliximab. AIM To determine the efficacy of adalimumab in CD patients who discontinued infliximab through a systematic review. METHODS Electronic searches of EMBASE and MEDLINE databases up to May 1, 2009, as well as abstracts from the AGA (2006-2008), ACG (2006-2007), UEGW (2006-2008) and CDDW (2006-2009) identified randomized-controlled trials (RCT) or open-labelled cohorts (OLC) evaluating the short-term and/or long-term efficacy of adalimumab in infliximab failures. The response rates for short-term (clinical response and remission at 4 weeks) and long-term (remission at 6 and 12 months) efficacy were considered. RESULTS A total of 1810 CD patients were identified among the 15 studies (2 RCT and 13 OLC). The majority of studies evaluated CD patients who either lost response or were intolerable to infliximab, although five OLCs permitted patients refractory to infliximab. Short-term clinical response (n = 9 articles) ranged from 41% to 83%. Long-term clinical remission at 12 months (n = 8 articles) ranged from 19% to 68%. The occurrence of severe adverse events ranged from 0% to 19% and four patients died. CONCLUSIONS Current RCT and OLC evidence suggest that adalimumab is an efficacious therapy for CD patients who discontinue infliximab.
