RESUMO
OBJECTIVE: In patients with Crohn's disease (CD) on combination therapy (infliximab and immunosuppressant) and stopping infliximab (cohort from the study of infliximab diSconTinuation in CrOhn's disease patients in stable Remission on combined therapy with Immunosuppressors (STORI)), the risk of short-term (≤6 months) and mid/long-term relapse (>6 months) was associated with distinct blood protein profiles. Our aim was to test the external validity of this finding in the SPARE cohort (A proSpective Randomized Controlled Trial comParing infliximAb-antimetabolites Combination Therapy to Anti-metabolites monotheRapy and Infliximab monothErapy in Crohn's Disease Patients in Sustained Steroid-free Remission on Combination Therapy). DESIGN: In SPARE, patients with CD in sustained steroid-free clinical remission and on combination therapy were randomly allocated to three arms: continuing combination therapy, stopping infliximab or stopping immunosuppressant. In the baseline serum of the STORI and SPARE (arm stopping infliximab) cohorts, we studied 202 immune-related proteins. The proteins associated with time to relapse (univariable Cox model) were compared between STORI and SPARE. The discriminative ability of biomarkers (individually and combined in pairs) was evaluated by the c-statistic (concordance analysis) which was compared with C-reactive protein (CRP), faecal calprotectin and a previously validated model (CEASE). RESULTS: In STORI and SPARE, distinct blood protein profiles were associated with the risk of short-term (eg, high level: CRP, haptoglobin, interleukin-6, C-type lectin domain family 4 member C) and mid/long-term relapse (eg, low level: Fms-related tyrosine kinase 3 ligand, kallistatin, fibroblast growth factor 2). At external validation, the top 10 biomarker pairs showed a higher c-statistic than the CEASE model, CRP and faecal calprotectin in predicting short-term (0.76-0.80 vs 0.74 vs 0.71 vs 0.69, respectively) and mid/long-term relapse (0.66-0.68 vs 0.61 vs 0.52 vs 0.59, respectively). CONCLUSION: In patients with CD stopping infliximab, we confirm that the risk of short-term and mid/long-term relapse is associated with distinct blood protein profiles showing the potential to guide infliximab withdrawal. TRIAL REGISTRATION NUMBER: NCT00571337 and NCT02177071.
RESUMO
BACKGROUND & AIMS: The aim of this study was to assess the long-term effectiveness and safety of risankizumab maintenance treatment in a large real-world cohort of patients with Crohn's Disease (CD). METHODS: From May 2021 to August 2023, all consecutive patients with CD treated with risankizumab in 25 GETAID centers have been retrospectively included. The primary endpoint was steroid-free clinical remission (Harvey Bradshaw Index [HBI] <5) at 52 weeks. RESULTS: Of the 174 patients included, 99%, 93%, and 96% had been previously exposed to anti-TNF, vedolizumab, and ustekinumab, respectively. All patients had received ≥3 biologics, and 108 (62%) had previous intestinal resection. Median follow-up was 13.7 months (interquartile range, 10.0-18.1 months). The rates of steroid-free clinical remission and clinical remission at week 26 were 47% (72/152) and 52% (79/152), and 46% (58/125), and 48% (60/125) at week 52, respectively. Risankizumab persistence rates were 94%, 89%, and 79% at weeks 12, 26, and 52, respectively. At the end of follow-up, 45 (45/174; 26%) patients had discontinued risankizumab (loss of response, 42%; primary failure, 37%; intolerance, 13%). Thirty-six patients (36/174; 20.9%) were hospitalized, and 22 (22/174; 12.6%) required intestinal resection. Fifty-one patients (29%) had an adverse event, including 26 (15%) serious adverse events (CD flare, n = 17). One death (myocardial infarction) and one cancer (papillary thyroid carcinoma) were observed. CONCLUSION: This is the first real-life study to report long-term outcomes in patients with refractory CD treated with risankizumab. One-half of the patients achieved steroid-free clinical remission after 1 year, and the safety profile was consistent with the literature.
RESUMO
BACKGROUND: Early endoscopic evaluation is recommended for assessment of postoperative recurrence (POR) of Crohn's disease (CD) but no further monitoring recommendations are available. AIM: To evaluate the long-term outcome of patients without endoscopic POR at first endoscopic assessment. METHODS: Retrospective four-centre study including consecutive CD patients with ileocolonic resection (ICR) without endoscopic POR (Rutgeerts score i0-i1) at first endoscopic assessment performed within 18 months from ICR. All patients had a clinical follow-up ≥24 months and at least one further endoscopic assessment. Main outcomes were endoscopic, clinical and surgical POR, need for rescue therapy and "delayed POR" (any need for rescue therapy or clinical or surgical POR) during follow-up. RESULTS: Overall, 183 patients were included (79% with risk factors for POR, 44% without postoperative prophylaxis). Endoscopic POR was observed in 42% of patients. Clinical POR-free survival was 89.4% and 81.5% at 3 and 5 years, and delayed POR-free survival was 76.9% and 63.4% at 5 and 10 years, respectively. In multivariate analysis, postoperative prophylaxis (HR .55; 95% CI .325-.942) and active smoking (HR 1.72; 95%CI 1.003-2.962) were independent risk factors for clinical POR, whereas presence of mild endoscopic lesions at index ileocolonoscopy (i1) was the only risk factor for delayed POR (HR 1.824; 95% CI 1.108-3.002). CONCLUSIONS: Long-term risk of POR among patients with no or mild endoscopic lesions at first ileocolonoscopy after surgery is steadily low, being higher among smokers, in the absence of postoperative prophylaxis and when mild endoscopic lesions are observed in the first endoscopic assessment.

OBJECTIVE: Despite being in sustained and stable remission, patients with Crohn's disease (CD) stopping anti-tumour necrosis factor α (TNFα) show a high rate of relapse (~50% within 2 years). Characterising non-invasively the biological profiles of those patients is needed to better guide the decision of anti-TNFα withdrawal. DESIGN: Ninety-two immune-related proteins were measured by proximity extension assay in serum of patients with CD (n=102) in sustained steroid-free remission and stopping anti-TNFα (infliximab). As previously shown, a stratification based on time to clinical relapse was used to characterise the distinct biological profiles of relapsers (short-term relapsers: <6 months vs mid/long-term relapsers: >6 months). Associations between protein levels and time to clinical relapse were determined by univariable Cox model. RESULTS: The risk (HR) of mid/long-term clinical relapse was specifically associated with a high serum level of proteins mainly expressed in lymphocytes (LAG3, SH2B3, SIT1; HR: 2.2-4.5; p<0.05), a low serum level of anti-inflammatory effectors (IL-10, HSD11B1; HR: 0.2-0.3; p<0.05) and cellular junction proteins (CDSN, CNTNAP2, CXADR, ITGA11; HR: 0.4; p<0.05). The risk of short-term clinical relapse was specifically associated with a high serum level of pro-inflammatory effectors (IL-6, IL12RB1; HR: 3.5-3.6; p<0.05) and a low or high serum level of proteins mainly expressed in antigen presenting cells (CLEC4A, CLEC4C, CLEC7A, LAMP3; HR: 0.4-4.1; p<0.05). CONCLUSION: We identified distinct blood protein profiles associated with the risk of short-term and mid/long-term clinical relapse in patients with CD stopping infliximab. These findings constitute an advance for the development of non-invasive biomarkers guiding the decision of anti-TNFα withdrawal.

Ulcerative colitis is a chronic inflammatory bowel disease. Approximately 20% of patients experience an acute severe attack during their life. In acute severe ulcerative colitis (ASUC), first-line therapy is intravenous (IV) steroids. In the absence of clinical improvement, 2 medical options can be considered: ciclosporin or infliximab.1 In ASUC, ciclosporin is commonly used as a bridging therapy for thiopurines. Pellet et al2 found that the same bridge strategy with vedolizumab was effective and can avoid colectomy. Given that an increasing number of patients with ASUC have been exposed to thiopurines, vedolizumab, and anti-tumor necrosis factor biologic therapies, newer approaches are needed in these patients, such as tofacitinib or ustekinumab. Ustekinumab, an antagonist of the p40 subunit of interleukin-12 and interleukin-23, has shown efficacy in ulcerative colitis and can be given in this indication.3 In this retrospective study, we evaluate the efficacy and safety of a bridge from calcineurin inhibitor to ustekinumab in patients with ASUC.

BACKGROUND & AIMS: Crohn's disease (CD) patients included in the Tailored Treatment With Infliximab for Active Crohn's Disease (TAILORIX) trial started infliximab in combination with an immunosuppressant for 1 year. The aim of the present study was to determine the long-term disease course beyond the study period. METHODS: We compared the outcomes of patients who did or did not reach the primary end point of the TAILORIX trial, defined as sustained corticosteroid-free clinical remission from weeks 22 through 54, with no ulcers on ileocolonoscopy at week 54. The primary outcome of this follow-up study was the progression-free survival of CD defined by anal or major abdominal surgery, CD-related hospitalization, or the need for a new systemic CD treatment. RESULTS: The 95 patients (median disease duration, 4.5 mo; interquartile range, 1.0-56.6 mo) analyzed, including 45 (47%) who achieved the primary end point, were followed up for a median duration of 64.2 months (interquartile range, 57.6-69.9 mo) after the end of the study period. There was no significant difference in CD progression-free survival at 1, 3, and 5 years between patients who achieved the TAILORIX primary end point and patients who did not (P = .64). No difference was observed between both groups for each component of CD progression: anal surgery, major abdominal surgery, CD-related hospitalization, or the need for a new systemic CD treatment. CONCLUSIONS: Achieving a sustained clinical remission off steroids with complete endoscopic remission in this cohort of 95 patients with early CD was not associated with less disease progression. Prospective trials to define the therapeutic goals that change the natural history of CD and prevent complications are needed.

BACKGROUND AND AIMS: Inflammatory bowel diseases (IBD), including Crohn's disease (CD) and ulcerative colitis (UC), and human immunodeficiency virus (HIV) both impact innate and adaptive immunity in the intestinal mucosa. As it is a rare situation, the intersection between HIV and IBD remains unclear, especially the impact of HIV infection on the course of IBD, and the drug safety profile is unknown. METHODS: We conducted a multicenter retrospective cohort study between January 2019 and August 2020. All adult patients with IBD and concomitant HIV infection were included. Each IBD patient with HIV was matched to two HIV-uninfected IBD patients. RESULTS: Overall, 195 patients with IBD were included, including 65 HIV-infected patients and 130 without HIV infection. Of the 65 infected patients, 22 (33.8%) required immunosuppressants and 31 (47.7%) biologics. In the HIV-infected group, the need for immunosuppressants (p = 0.034 for CD and p = 0.012 for UC) and biologics (p = 0.004 for CD and p = 0.008 for UC) was significantly lower. The disease course, using a severity composite criterion, was not significantly different between the two groups for CD (hazard ration (HR) = 1.3 [0.7; 2.4], p = 0.45) and UC (HR, 1.1 [0.5; 2.7], p = 0.767). The overall drug safety profile was statistically similar between the two groups. CONCLUSION: Although HIV-infected patients receive less treatments, the course of their IBD did not differ than uninfected, suggesting that HIV infection might attenuate IBD. The drug safety profile is reassuring, allowing physician to treat these patients according to current recommendations.

INTRODUCTION: The objective of this study was to describe the efficacy and safety of infliximab (IFX) reintroduction in Crohn's disease (CD) after stopping for loss of response or intolerance. METHODS: We conducted a prospective multicenter observational cohort study including adult patients with clinically (CD Activity Index >150) and objectively active luminal CD in whom IFX was reintroduced after at least 6 months of discontinuation. The reasons for the initial discontinuation could be a secondary loss of response or IFX intolerance. The reintroduction schedule included 3 IFX infusions at weeks 0, 4, and 8, after a systematic premedication. The primary end point was the efficacy of IFX retreatment at week 26 defined by a CD Activity Index of <150 in the absence of IFX discontinuation or use of corticosteroids, surgery, or other biologic. RESULTS: At week 26, 24 patients (35%) among the 69 analyzed reached the primary end point. No significant difference was observed between rates of clinical remission at week 26 in patients with prior LOR (n = 48) and those with IFX intolerance (n = 21) (35% and 33%, P = 0.87, respectively). Thirty-two acute infusion reactions were recorded in 27 patients, leading to withdrawal of IFX in 20 patients. No pharmacokinetic characteristic at baseline but detection of positive anti-drug antibodies at week 4 was predictive of IFX failure or infusion reaction at week 26. DISCUSSION: In this first prospective cohort study, IFX retreatment was safe and effective in one-third of the patients with CD, regardless the reason of prior discontinuation. Early detection of anti-drug antibodies can predict subsequent IFX reintroduction failure and infusion reactions.

OBJECTIVE: The association of IgA vasculitis (IgAV) and IBD is rarely described, mainly during anti-TNF-α therapy. We aimed to describe the association of IgAV and IBD. METHODS: We retrospectively analysed the association of IgAV and IBD through the implication of the GETAID and FVSG networks. Characteristics of IBD and IgAV were collected using a standardized case report form. RESULTS: Forty-three cases were included. IBD [mainly Crohn's disease (CD) in 58%] preceded IgAV in 38 (88%), with median interval of 9.2 (IQR 5.4-15.4) years. In these 38 patients, at IgAV diagnosis, five (13%) had active IBD and 28 (74%) were treated with anti-TNF-α for a median duration of 31.5 (IQR 19-56) months. Main IgAV manifestations were purpura all patients (100%), joints in 20/35 (57%), renal in 15/35 (43%) and gastrointestinal in 11/35 (31%) involvement. IgAV was treated with glucocorticoids in 25 (66%), colchicine in six (16%), CYC in six (16%) and anti-TNF-α were discontinued in 15/28 (54%). No IgAV relapse occurred when TNF-α blockers were stopped, vs 23% in patients pursuing it. Conversely, five (33%) had IBD flare or complication after anti-TNF-α cessation vs one (8%) in those continuing biologics. Anti-TNF-α were resumed in six (40%), with subsequent IgAV relapse in four (67%). CONCLUSIONS: This large cohort suggests that TNF-α blockers may promote the onset of IgAV in IBD. Discontinuation of anti-TNF-α was associated with vasculitis remission but increased risk of IBD relapses, whereas continuation of anti-TNF-α was associated with IBD remission but vasculitis relapse.

BACKGROUND AND AIMS: In Crohn's disease (CD), a composite therapeutic target was recently recommended, including both objective measurement (endoscopic remission) and Patient-Reported Outcomes (resolution of abdominal pain and normalization of bowel function). All dimensions of health-related quality of life (HRQoL) are impacted: not only bowel symptoms but also systemic symptoms, emotional wellbeing and social function. Thus, understanding the predictors of each HRQoL dimension would improve patient management. However, analysis of these factors has only been found in a few publications, with some limitations. Therefore, this study aimed to explore the evolution of the HRQoL of CD patients during six months after initiation of anti-TNF and to identify its predictors. METHODS: We analyzed data of 56 patients included in a multicenter prospective cohort study (COQC-PIT). HRQoL measures (using IBDQ-32) and data related to patient, disease and treatment characteristics were collected every two months. Generalized estimating equations were used. RESULTS: Overall HRQoL was significantly improved 2 months after anti-TNF initiation, and then stagnated. Patient, disease, and treatment characteristics have differentiated impacts on the overall score and on each dimension of quality of life. Subcutaneous anti-TNF had no significant effect on overall HRQoL, improving only emotional function and bowel symptoms. Concomitant use of corticosteroids and/or immunomodulators impaired almost all dimensions. Having children or working altered bowel symptoms. Disease duration and active smoking negatively impact emotional function and systemic symptoms. CONCLUSIONS: Each HRQoL dimension, not only bowel symptoms, and their influencing factors should therefore be considered in medical decision-making, especially in months following the initiation of a new treatment such as anti-TNF.

BACKGROUND AND OBJECTIVE: Anti-TNFs have been shown to significantly improve the health-related quality of life (HRQoL) in Crohn's disease (CD) patients. The purpose of this study was to investigate to what extend the patients' preferences for these intravenous (IV) and subcutaneous (SC) treatments differ based on respondents' quality of life. An online discrete choice experiment (DCE) was conducted to understand patient trade-offs in treatment choice. METHODS: Fifty-seven Crohn's disease anti-TNF naïve patients were asked to choose between two different scenarios, considering the following attributes: mode of administration (MODE), total availability for injection (TIME), speed of onset (DELAY), risk of anti-TNF administration despite a contraindication (RISK) and total monthly out-of-pocket expenses (COST). At the same time, patients completed the IBDQ-32 questionnaire. Conditional logit models without and with interaction terms were estimated to evaluate attribute weights. RESULTS: Patients preferred to self-administer SC anti-TNF rather than have a primary care nurse do it, whereas the preference for IV route was negative. After adding interaction terms however, the IV route became preferred for patients with impaired HRQoL, this preference having decreased as HRQoL increased. Surprisingly, patients with impaired HRQoL were less willing to spend more time on treatment, and this effect diminished as HRQoL (overall and in each dimension) became higher. CONCLUSIONS: HRQoL level changed patients' preferences for the anti-TNF treatment. The results suggest the need to optimise the management of IV infusions in the hospital and reinforce the importance of patient-reported outcome measures (PROMS) as a common practice to improve shared medical decision making.

INTRODUCTION: There are currently no comparative data on the efficacy and safety of vedolizumab and ustekinumab in ulcerative colitis (UC) after anti-TNF therapy fails. METHODS: We retrieved the full datasets of two observational, multicentre, retrospective studies of patients with UC for whom anti-TNF therapy failed and the patients were then treated with either vedolizumab or ustekinumab. The outcomes included steroid-free clinical remission, clinical remission, treatment persistence, colectomy, hospitalization, and serious and infectious adverse events. Propensity scores weighted comparison was applied. RESULTS: In total, 121 patients were included in the vedolizumab group and 97 were included in the ustekinumab group. At week 14 and week 52, in the weighted cohort, no difference was found between vedolizumab and ustekinumab for steroid-free clinical remission (OR = 0.55 [0.21-1.41], p = .21 and 0.94 [0.40-2.22], p = .89, respectively). There was no difference between vedolizumab and ustekinumab for secondary outcomes such as clinical remission, hospitalization, UC-related surgery, treatment persistence and serious and infectious adverse events. CONCLUSION: In patients with UC for whom anti-TNF therapy failed, no difference was found between vedolizumab and ustekinumab after propensity scores weighted comparison. Further studies are required to determine predictive factors of the efficacy of both biological agents.

BACKGROUND: No study has performed a face-to-face comparison of biologics after the failure of the first anti-TNF agent in patients with Crohn's disease (CD). The aim of the study was to compare the efficacy of biologics in this setting. METHODS: Patients with CD who were refractory to a first anti-TNF agent, and treated with ustekinumab (UST), vedolizumab (VDZ), or a second anti-TNF drug as a second-line biological agent at 10 French tertiary centres from 2013 to 2019 were retrospectively included in this study. RESULTS: Among the 203 patients included, 90 (44%) received UST, 42 (21%) received VDZ and 71 (35%) received a second anti-TNF agent. The first anti-TNF agent was discontinued due to a primary nonresponse in 42 (21%) patients. At weeks 14-24, the rates of steroid-free remission were similar between the UST, VDZ and second anti-TNF groups (29%, 38% and 44%, respectively, p = 0.15). With a mean follow-up of 118 weeks, drug survival was shorter for patients who received ustekinumab treatment (p = 0.001). In the case of trough level less than 5 µg/ml, patients treated with a second anti-TNF agent had a higher postinduction remission rate (p = 0.002), and drug survival (p = 0.0005). No other relevant factors were associated with treatment efficacy, including trough levels greater than 5 µg/ml. CONCLUSIONS: VDZ, UST and a second anti-TNF agent exhibit similar efficacy in the short term, as second-biological line treatment in patients with CD who are refractory to a first anti-TNF agent, but shorter drug maintenance is observed for patients treated with UST.

BACKGROUND: Iron deficiency (ID) is a frequent condition in patients with inflammatory bowel disease (IBD). AIM: Our aim was to investigate the prevalence of ID in patients with IBD. METHODS: This was a prospective multicenter cross-sectional study conducted in 21 gastroenterology departments in France between January and March 2020. All adult patients with confirmed IBD who were admitted to the hospital were eligible for inclusion. ID was defined as ferritinemia ≤ 100 µg/L in patients with signs of inflammation (C-reactive protein (CRP) ≥ 5 mg/L) or ferritinemia < 30 µg/L in the absence of inflammation. RESULTS: In total, 1036 IBD (685 Crohn's disease and 351 ulcerative colitis) patients (52.1% women) with a mean age of 41.8 ± 15.5 years were recruited. Approximately half of the patients (504, 51.1%) were in disease remission at the time of enrollment. Systematic monitoring of iron status was performed in 12/21 (57%) participating centers, including measurements of ferritin (12/12, 100%), hemoglobin (11/12, 92%), transferrin saturation (TSAT) (6/12, 50.0%), and serum iron (5/12, 42%). About one-fifth of the patients had been treated with intravenous iron (218, 21.0%), whereas only a small percentage received oral iron (36, 3.5%). ID occurred in 97 patients (23.7% CI 95% 19.8-28.1). Patients with moderate/severe IBD activity (OR: 3.66; CI 95% 24.4-61.2; p = 0.007) or concomitant anemia (OR: 3.66; CI 95% 1.97-6.78; p < 0.001) had an increased likelihood of having ID. CONCLUSION: Patients with moderate/severe IBD activity or concomitant anemia are at increased risk of ID. Early detection and management of ID in patients with IBD is recommended.

BACKGROUND AND AIMS: Patients with inflammatory bowel disease have an increased risk of venous thromboembolism (VTE) and cardiovascular disease (CVD). The study aims to determine the prevalence of CVD and VTE risk factors in a large population of patients with ulcerative colitis (UC). METHODS: We conducted a cross-sectional study in 33 French and Belgium referral centers. A questionnaire was developed to explore self-reported risk factors for VTE and CVD, based on the latest international guidelines, in consecutive patients with UC. RESULTS: A total of 1071 patients with UC were included. There were 539 women (50.3%), and the median age of patients was 44 years [32; 57]. The median disease duration was 10 years [6; 17]. In the cohort, 36.5% of patients reported no cardiovascular risk factor (CVRF) and 72% had ≤ 1 CVRF. Regarding cardiovascular risk markers (CVRM) 36.9% of patients reported no CVRM and 78% had ≤ 1 CVRM. Of the 1071 patients, 91.3% of patients reported no VTE strong risk factor and 96% had ≤ 1 VTE moderate risk factor. CONCLUSION: This is the first cohort specifically designed to assess both VTE and CVD risks in patients with UC. More than one third of patients with UC had no CVRF and around three quarters had ≤ 1 CVRF. In addition, more than nine out of ten patients had no VTE strong risk factor and ≤ 1 moderate risk factor. Physicians should be aware of these factors in their patients.

BACKGROUND & AIMS: The Rutgeerts' scoring system is used to evaluate patients with Crohn's disease (CD) following ileocolic resection, based on endoscopic findings at the anastomosis and in the neoterminal ileum. We investigated rates of clinical and surgical recurrence of CD after surgery and effect of therapy modification based on post-operative endoscopic findings. METHODS: We collected data from 365 adults with CD (20% with Rutgeerts' score i0, 10% with score i1, 49% with score i2, 12% with score i3, 9% with score i4) who underwent ileocolonoscopy within 12 months of ileocolic resection with anastomosis from 2000 through 2013 at 2 centers in Belgium and France. Patients were followed for 3 y or more after the ileocolonoscopy. Clinical post-operative recurrence (POR) was defined as occurrence of CD symptoms along with biologic, radiologic, and/or endoscopic features of disease activity; modified surgical POR was defined as either an endoscopic or surgical intervention. RESULTS: After a median follow-up time of 88 months, 48% of patients had clinical POR and 26% had modified surgical POR. Rates of survival without clinical POR or a modified surgical POR were lower in patients with Rutgeerts' scores of i2, i3, or i4 compared to patients with scores of i0 or i1 (P < .001 and P = .02). New immunosuppressant or biological therapy was initiated following endoscopy in 129/254 patients (51%) with Rutgeerts' score of i2, i3, or i4 vs 7/111 patients (6%) with scores of i0 or i1 (odds ratio for new therapy, 14.9; 95% CI, 7.1-36.8; P < .001). A modest decrease in risk of clinical POR was observed for patients with Rutgeerts scores of i3 or i4 after initiation of immunosuppressive or biological therapy based on endoscopic findings (Breslow P = .03), but this was not observed for patients with scores of i2 (Breslow P = .46). CONCLUSIONS: Use of immunosuppressants and tumor necrosis factor antagonists to treat patients with an asymptomatic endoscopic post-operative recurrence of CD did not reduce long-term risk of clinical recurrence in patients with Rutgeerts' scores of i2, but it had a small effect in patients with scores of i3 or i4.

BACKGROUND & AIMS: Higher infliximab trough levels are associated with clinical and endoscopic remission in patients with Crohn's disease (CD). We investigated pharmacodynamic features of infliximab and radiological healing. METHODS: We performed a substudy of the TAILORIX trial (patients with active luminal CD in Europe, treated with infliximab), analyzing baseline and week 54 magnetic resonance enterography (MRE) data. MREs were scored using the MaRIA score by blinded central readers. Radiologic response and remission were defined, based on MaRIA criteria in all segments, as scores below 11 and 7, respectively. We collected data on infliximab trough levels, biomarkers, and endoscopic findings. Our primary aim was to evaluate pharmacodynamic features associated with radiologic response and remission, based on MRE assessments at baseline and at 54 weeks after initiation of infliximab therapy. RESULTS: We analyzed data from 36 patients (50% female; median age 35.7 years; interquartile age range, 25.6-48.6 years; median disease duration, 1.5 months; interquartile duration range, 0.6-22.4 months). At week 54 of treatment, 36.4% of patients had a radiologic response, 30.3% of patients were in remission, and 71% had endoscopic features of remission. At baseline, there was a correlation between the CD endoscopic index of severity and MaRIA scores (κ = 0.46; P = .008), but we found no correlation at week 54 (κ = 0.06; P = .75). Radiologic remission correlated with infliximab trough level at week 14 (P = .049) when the infliximab trough level cut-off value was set at 7.8 µg/mL (area under the curve, 0.74; 75% sensitivity; 86% specificity; 90% negative predictive value; 57% positive predictive value). Radiologic response correlated with infliximab trough levels at week 14 (P = .048) when the infliximab trough level cut-off value was set at 7.8 µg/mL (area under the curve, 0.73; 70% sensitivity; 90% specificity; 86% negative predictive value; 78% positive predictive value) and with continuous pharmacologic evidence of response (infliximab trough levels above 5.0 µg/mL at all time points) (P = .034). CONCLUSIONS: In a substudy of data from the TAILORIX trial of patients with active luminal CD, we identified a relationship between exposure to infliximab and radiologic evidence of outcomes.

BACKGROUND/AIMS: Few data on the evolution of endoscopic findings are available in patients with acute severe ulcerative colitis (ASUC). The aim of this study was to describe this evolution in a prospective cohort. METHODS: Patients admitted for a steroid-refractory ASUC and included in a randomized trial comparing infliximab and cyclosporine were eligible if they achieved steroid-free clinical remission at day 98. Flexible sigmoidoscopies were performed at baseline, days 7, 42 and 98. Ulcerative colitis endoscopic index of severity (UCEIS) and its sub-scores - vascular pattern, bleeding and ulceration/erosion - were post-hoc calculated. Global endoscopic remission was defined by a UCEIS of 0, and partial endoscopic remission by any UCEIS sub-score of 0. RESULTS: Among the 55 patients analyzed (29 infliximab and 26 cyclosporine), 49 (83%) had UCEIS ≥6 at baseline at baseline. Partial endoscopic remission rates were higher for bleeding than for vascular pattern and for ulcerations/erosions at day 7 (20% vs. 4% and 5% (n = 55); p = .004 and p=.04), for bleeding and ulceration/erosion than for vascular pattern at day 42 [63% and 65% vs. 33% (n=54); p<.001 for both] and at day 98 [78% and 92% vs. 56% (n = 50); p = .007 and p < .001]. Global endoscopic remission rates at day 98 were higher in patients treated with infliximab than with cyclosporine [73% vs. 25% (n = 26 and 24); p < .001]. CONCLUSION: In steroid-refractory ASUC patients responding to a second-line medical therapy, endoscopic remission process started with bleeding remission and was not achieved in half the patients at day 98 for vascular pattern. Infliximab provided a higher endoscopic remission rate than cyclosporine at day 98.

BACKGROUND & AIMS: Noninvasive tests to measure endoscopic activity in patients with Crohn's disease (CD) have limitations. We aimed to develop a test to identify patients in remission, based on endoscopic analysis, and monitor CD activity based on serum levels of proteins. METHODS: We developed a test to measure 13 proteins in blood (ANG1, ANG2, CRP, SAA1, IL7, EMMPRIN, MMP1, MMP2, MMP3, MMP9, TGFA, CEACAM1, and VCAM1), called the endoscopic healing index [EHI], using samples from 278 patients with CD from a multinational training cohort. We validated the test using 2 independent cohorts of patients with CD: 116 biologic-naive patients with early-stage CD (validation cohort 1) and 195 biologic-exposed patients with chronic CD (validation cohort 2). The ability of the test to identify patients with active disease vs patients in remission (defined as a simple endoscopic score for CD of ≤2 and ≤1 in each segment, or a total CD endoscopic index of severity score <3) was assessed by using area under receiver operating characteristic curve (AUROC) analysis. The diagnostic accuracy of the test was compared with that of measurement of serum C-reactive protein (CRP) and fecal calprotectin. RESULTS: The EHI scores range from 0 to 100 units; higher scores indicate more severe CD activity, based on endoscopy findings. The EHI identified patients in remission with an AUROC of 0.962 in validation cohort 1 (95% confidence interval, 0.942-0.982) and an AUROC of 0.693 in validation cohort 2 (95% confidence interval, 0.619-0.767), regardless of CD location or phenotype. A cutoff value of 20 points identified patients in remission with the highest level of sensitivity (97.1% in validation cohort 1 and 83.2% in validation cohort 2), with specificity values of 69.0% and 36.6%, respectively. A cutoff value of 50 points identified patients in remission with the highest level of specificity (100% in validation cohort 1 and 87.8% in validation cohort 2), with sensitivity values of 37.3% and 30.0%, respectively. The EHI identified patients in remission with a significantly higher AUROC value than the test for CRP (0.876, P < .001 in validation cohort 1 and 0.624, P = .109 in validation cohort 2). In analysis of patients with available FC measurements, the AUROC value for the EHI did not differ significantly from that of measurement of FC (AUROC, 0.950 for EHI vs AUROC, 0.923 for FC; P = .147 in validation cohort 1 and AUROC, 0.803 for EHI vs AUROC, 0.854 for FC; P = .298 in validation cohort 2). CONCLUSIONS: We developed an index called the EHI to identify patients with CD in endoscopic remission based on blood levels of 13 proteins. The EHI identified patients with resolution of endoscopic disease activity, with good overall accuracy, although with variation between the 2 cohorts assessed. The EHI AUROC values were comparable to measurement of FC and higher than measurement of serum CRP. The test might be used in practice to assess endoscopic activity in patients with CD.

BACKGROUND & AIMS: We investigated the effects of inducing deep remission in patients with early Crohn's disease (CD). METHODS: We collected follow-up data from 122 patients (mean age, 31.2 ± 11.3 y) with early, moderate to severe CD (median duration, 0.2 years; interquartile range, 0.1-0.5) who participated in the Effect of Tight Control Management on CD (CALM) study, at 31 sites, representing 50% of the original CALM patient population. Fifty percent of patients (n = 61) were randomly assigned to a tight control strategy (increased therapy based on fecal level of calprotectin, serum level of C-reactive protein, and symptoms), and 50% were assigned to conventional management. We categorized patients as those who were vs were not in deep remission (CD endoscopic index of severity scores below 4, with no deep ulcerations or steroid treatment, for 8 or more weeks) at the end of the follow-up period (median, 3.02 years; range, 0.05-6.26 years). The primary outcome was a composite of major adverse outcomes that indicate CD progression during the follow-up period: new internal fistulas or abscesses, strictures, perianal fistulas or abscesses, or hospitalization or surgery for CD. Kaplan-Meier and penalized Cox regression with bootstrapping were used to compare composite rates between patients who achieved or did not achieve remission at the end of the follow-up period. RESULTS: Major adverse outcomes were reported for 34 patients (27.9%) during the follow-up period. Significantly fewer patients in deep remission at the end of the CALM study had major adverse outcomes during the follow-up period (P = .01). When we adjusted for potential confounders, deep remission (adjusted hazard ratio, 0.19; 95% confidence interval, 0.07-0.31) was significantly associated with a lower risk of major adverse outcome. CONCLUSIONS: In an analysis of follow-up data from the CALM study, we associated induction of deep remission in early, moderate to severe CD with decreased risk of disease progression over a median time of 3 years, regardless of tight control or conventional management strategy.
