RESUMO
PURPOSE: Crohn's disease (CD) is a progressive disorder leading to cumulative bowel damage. The Lémann index is a validated tool that can help in monitoring the progression of the disease and evaluating the effectiveness of different therapies. Our aim was to describe the main radiological findings in incidentally diagnosed CD and to evaluate bowel damage in this subgroup compared to patients diagnosed at later stages. METHODS: Patients with an incidental diagnosis of CD during the colorectal cancer screening program were compared to controls with a CD cohort diagnosed after symptomatic onset and matched 1:1 by disease extent. All cross-sectional examinations were centrally read, performing a descriptive analysis of the main findings and calculation of Lémann index. RESULTS: Thirty-eight patients were included: 19 with preclinical CD (median age 55 years (IQR, 54-62), 53% male, 74% non-smokers; 74% B1 and 26% B2) and 19 matched-controls with symptomatic CD. In those with preclinical CD, the most frequent transmural findings on MRE were contrast enhancement (79%), wall thickening (79%), followed by lymphadenopathy (68%), edema (42%), and increased vascularity (42%). Among those with strictures, controls showed a higher rate of preestenotic dilation (100% vs. 0%, p = 0.01). Bowel damage assessment revealed no statistically significant differences in the Lémann index between preclinical CD and controls (p = 0.95). A statistically significant higher score in the colonic/rectum score was observed (p = 0.014). CONCLUSION: Patients with preclinical CD demonstrate similar radiological findings and degree of bowel damage as new-onset symptomatic CD.

BACKGROUND AND AIMS: Familial inflammatory bowel disease (IBD) history is a controversial prognostic factor in IBD. We aimed to evaluate the impact of a familial history of IBD on the use of medical and surgical treatments in the biological era. METHODS: Patients included in the prospectively maintained ENEIDA database and diagnosed with IBD after 2005 were included. Familial forms were defined as those cases with at least one first-degree relative diagnosed with IBD. Disease phenotype, the use of biological agents, or surgical treatments were the main outcomes. RESULTS: A total of 5263 patients [2627 Crohn's disease (CD); 2636 ulcerative colitis (UC)] were included, with a median follow-up of 31 months. Of these, 507 (10%) corresponded to familial forms. No clinical differences were observed between familial and sporadic IBD forms except a lower age at IBD diagnosis and a higher rate of males in familial forms of UC. In CD, the proportions of patients treated with thiopurines (54.4% vs 46.7%; P = .015) and survival time free of thiopurines (P = .009) were lower in familial forms. No differences were found regarding the use of biological agents. Concerning surgery, a higher rate of intestinal resections was observed in sporadic CD (14.8% vs 9.9%, P = .027). No differences were observed in UC. CONCLUSIONS: In the era of biological therapies, familial and sporadic forms of IBD show similar phenotypes and are managed medically in a similar way; whether these is due to lack of phenotypical differences or an effect of biological therapies is uncertain. What is already known on this topic: IBD's etiopathogenesis points to an interaction between environmental and genetic factors, being familial history a controversial prognostic factor. Biological agents use and need for surgery regarding familial or sporadic forms of IBDs present conflicting results. What this study adds: Familial and sporadic forms of IBD have similar phenotypes and are managed medically and surgically in a similar way. How this study might affect research, practice or policy: Familial aggregation should not be considered a factor associated with more aggressive disease.
RESUMO
INTRODUCTION: The prevalence of penetrating complications in Crohn's disease (CD) increases progressively over time, but evidence on the medical treatment in this setting is limited. The aim of this study was to evaluate the effectiveness of biologic agents in CD complicated with internal fistulizing disease. METHODS: Adult patients with CD-related fistulae who received at least 1 biologic agent for this condition from the prospectively maintained ENEIDA registry were included. Exclusion criteria involved those receiving biologics for perianal disease, enterocutaneous, rectovaginal, anastomotic, or peristomal fistulae. The primary end point was fistula-related surgery. Predictive factors associated with surgery and fistula closure were evaluated by multivariate logistic regression and survival analyses. RESULTS: A total of 760 patients from 53 hospitals (673 receiving anti-tumor necrosis factors, 69 ustekinumab, and 18 vedolizumab) were included. After a median follow-up of 56 months (interquartile range, 26-102 months), 240 patients required surgery, with surgery rates of 32%, 41%, and 24% among those under anti-tumor necrosis factor, vedolizumab, or ustekinumab, respectively. Fistula closure was observed in 24% of patients. Older patients, ileocolonic disease, entero-urinary fistulae, or an intestinal stricture distal to the origin of the fistula were associated with a higher risk of surgery, whereas nonsmokers and combination therapy with an immunomodulator reduced this risk. DISCUSSION: Biologic therapy is beneficial in approximately three-quarters of patients with fistulizing CD, achieving fistula closure in 24%. However, around one-third still undergo surgery due to refractory disease. Some patient- and lesion-related factors can identify patients who will obtain more benefit from these drugs.

INTRODUCTION: Immunomodulators and biologics are two of the main drugs used for the treatment of inflammatory bowel disease (IBD). Some of these agents have been associated with certain infections and lymphoproliferative disorders, including Epstein-Barr virus (EBV) infection. Our aim was to determine the influence of immunosuppression in the EBV viral load in patients with IBD. MATERIALS AND METHODS: We prospectively included naïve patients with IBD who were starting immunosuppressive therapy in four IBD Units. All patients were assessed at baseline and four months after starting immunosuppression for clinical disease activity, biomarkers, EBV serology (IgM VCA, IgG VCA and IgG EBNA) and viral load. RESULTS: Thirty-two patients were included. At baseline, all patients showed positive results for IgG VCA or IgG EBNA with undetectable EBV viral load. No patient showed detectable EBV viral load after starting the immunosuppressive therapy. CONCLUSION: Immunosuppression did not influence on EBV viral load in the short-term in naïve IBD patients.

BACKGROUND & AIMS: Inflammatory bowel disease (IBD) is a chronic disease usually diagnosed after the appearance of gastrointestinal symptoms. Little is known about IBD progression during its early and even preclinical phases. We aimed to determine the number of new incidental diagnoses of IBD in an older population, and evaluate disease progression from its early stages. METHODS: We performed a retrospective analysis of 31,005 colonoscopies performed during colorectal cancer screening of patients with positive results from fecal immunochemical tests, at 11 centers in the Basque Country (Spain) from 2009 through 2014. We collected clinical and laboratory data from all asymptomatic individuals suspected to have IBD during screening colonoscopies, with histologic confirmation. RESULTS: Colonoscopy screening led to 79 new diagnoses of ulcerative colitis, 24 of Crohn's disease, and 7 of unclassified colitis (average patient age, 57 y; interquartile range, 52-62 y; 57% male). Eleven patients had symptoms before colonoscopy and were excluded from the analysis. Among those patients who were asymptomatic at diagnosis, 36% developed symptoms after a follow-up period of 25 months (interquartile range, 10.5-42 mo), mostly rectal bleeding and diarrhea. Treatment was prescribed for 81 patients (88%), and 2 cases required surgery. CONCLUSIONS: We analyzed data from a large cohort of patients with IBD diagnosed at early or even preclinical stages, from an older population. New incidental diagnoses of IBD were made in 0.35% of individuals undergoing a population-based screening colonoscopy-most were classified as ulcerative colitis. Approximately one third of patients developed symptoms during the follow-up period.

AIMS: To establish recommendations for the management of psychological problems affecting patients with inflammatory bowel disease (IBD). METHODS: A meeting of a group of IBD experts made up of doctors, psychologists, nurses and patient representatives was held. The following were presented: 1) Results of a previous focal group, 2) Results of doctor and patient surveys, 3) Results of a systematic review of tools for detecting anxiety and depression. A guided discussion was then held about the most important psychological and emotional problems associated with IBD, appropriate referral criteria and situations to be avoided. The validated instrument most applicable to clinical practice was selected. A recommendations document and a Delphi survey were designed. The survey was sent to the group and to a scientific committee of the GETECCU group in order to establish the level of agreement with these recommendations. RESULTS: Fifteen recommendations were established linked to 3 key processes: 1) What steps should be taken to identify psychological problems at an IBD appointment; 2) What are the criteria for referring patients to a mental health specialist; 3) How to approach psychological problems. CONCLUSIONS: Resources should be made available to healthcare professionals so that they can treat these problems during consultations, identify the disorders which could affect the clinical course of the disease and determine their impact on the patient's life in order that these can be treated and followed up by the most suitable professional. These recommendations could serve as a basis for redesigning IBD services or processes and as justification for the training of healthcare personnel.

BACKGROUND AND AIMS: Inflammatory bowel disease is a chronic disorder of the gastrointestinal tract. Tacrolimus is a calcineurin inhibitor used in the prophylaxis of rejection after a solid organ transplant. There is some evidence for its use in inflammatory bowel disease, although there is a lack of information about the patients who will benefit the most with this drug and the prognostic factors for a favorable response. MATERIAL AND METHODS: We performed a multicentric retrospective study evaluating all the patients who have received tacrolimus in the last 10 years as a treatment for IBD in our area. RESULTS: A total of 20 patients, 12 with Crohn's disease and 8 with ulcerative colitis, were included in four hospitals. The two most common indications were steroid-dependency and fistulizing Crohn's disease. The median time receiving tacrolimus was 11 months. In 12 patients the treatment was stopped. The main reasons for drug withdrawal were absence or loss of response. The median clinical follow-up was 35.5 months. Overall, a 25% achieved clinical remission and 40% were in partial response. Biologics-naïve patients demonstrated a significantly better remission rate as compared with those that were not (80 vs 7%). Patients who achieved remission were more likely to have a significant reduction in C-reactive protein values 1 month after starting the drug. Seven patients required surgery during the follow- up period. CONCLUSIONS: Patients naïve to biologics showed a significantly better response to tacrolimus. A reduction in C-reactive protein one month after starting this drug was associated with clinical remission.

BACKGROUND AND AIMS: Clinical trials and real-life studies with ustekinumab in Crohn's disease [CD] have revealed a good efficacy and safety profile. However, these data are scarcely available in elderly patients. Therefore, we aim to assess the effectiveness and safety of ustekinumab in elderly patients with CD. METHODS: Elderly patients [>60 years old] from the prospectively maintained ENEIDA registry treated with ustekinumab due to CD were included. Every patient was matched with two controls under 60 years of age, according to anti-tumour necrosis factor use and smoking habit. Values for the Harvey-Bradshaw Index [HBI], endoscopic activity, C-reactive protein [CRP] and faecal calprotectin [FC] were recorded at baseline and at weeks 16, 32 and 54. RESULTS: In total, 648 patients were included, 212 of whom were elderly. Effectiveness was similar between young and elderly patients during the follow-up. Steroid-free remission was similar at week 16 [54.6 vs 51.4%, pâ =â 0.20], 32 [53.0% vs 54.5%, pâ =â 0.26] and 54 [57.8% vs 51.1%, pâ =â 0.21]. Persistence of ustekinumab as maintenance therapy was similar in both age groups [log-rank test; pâ =â 0.91]. There was no difference in the rate of adverse effects [14.2% vs 11.2%, pâ =â 0.350], including severe infections [7.1% vs 7.3%, pâ =â 1.00], except for the occurrence of de novo neoplasms, which was higher in older patients [0.7% vs 4.3%, pâ =â 0.003]. CONCLUSIONS: Ustekinumab is as effective in elderly patients with CD as it is in non-elderly patients. The safety profile also seems to be similar except for a higher rate of de novo neoplasms, probably related to the age of the elderly patients.

Inflammatory bowel disease (IBD) is characterised by chronic inflammation of the gastrointestinal tract. Although its aetiology remains unknown, environmental and genetic factors are involved in its development. Regarding genetics, more than 200 loci have been associated with IBD but the transferability of those signals to the Basque population living in Northern Spain, a population with distinctive genetic background, remains unknown. We have analysed 5,411,568 SNPs in 498 IBD cases and 935 controls from the Basque population. We found 33 suggestive loci (p < 5 × 10-6) in IBD and its subtypes, namely Crohn's Disease (CD) and Ulcerative Colitis (UC), detecting a genome-wide significant locus located in HLA region in patients with UC. Those loci contain previously associated genes with IBD (IL23R, JAK2 or HLA genes) and new genes that could be involved in its development (AGT, BZW2 or FSTL1). The overall genetic correlation between European populations and Basque population was high in IBD and CD, while in UC was lower. Finally, the use of genetic risk scores based on previous GWAS findings reached area under the curves > 0.68. In conclusion, we report on the genetic architecture of IBD in the Basque population, and explore the performance of European-descent genetic risk scores in this population.

BACKGROUND: A significant percentage of patients treated with ustekinumab may lose response. Our aim was to evaluate the short-term efficacy and safety of intravenous re-induction with ustekinumab in patients with Crohn's disease who have lost the response to the treatment. METHODS: This is a retrospective, observational, multicenter study. Treatment efficacy was measured at week 8 and 16; clinical remission was defined when the Harvey-Bradshaw Index was ≤4 points, and clinical response was defined as a decrease of ≥3 points in the index compared with the baseline. Adverse events and treatment decisions after re-induction were also collected. RESULTS: Fifty-three patients from 13 centers were included. Forty-nine percent had previously failed to respond to 2 biological treatments, and 24.5% had failed to respond to 3. The average exposure time to ustekinumab before re-induction was 17.7 ± 12.8 months. In 56.6% of patients, the administration interval had been shortened to every 4 to 6 weeks before re-induction. At week 8 and 16 after re-induction, 49.0% (n = 26) and 43.3% (n = 23), respectively, were in remission, whereas 64.1% (n = 34) and 52.8% (n = 28) had a clinical response. Patients who achieved remission at week 16 had lower C-reactive protein levels than those who did not respond (2.8 ± 1.6 vs 12.5 ± 9.5 mg/dL; P = 0.001). No serious adverse events related to re-induction were observed. CONCLUSION: Intravenous re-induction with ustekinumab is an effective and safe strategy that recovers the response in approximately half of the patients with refractory Crohn's disease who experience a loss of response. Re-induction can be attempted before switching out of the therapy class.

BACKGROUND: Previous studies comparing immigrant ethnic groups and native patients with IBD have yielded clinical and phenotypic differences. To date, no study has focused on the immigrant IBD population in Spain. METHODS: Prospective, observational, multicenter study comparing cohorts of IBD patients from ENEIDA-registry who were born outside Spain with a cohort of native patients. RESULTS: We included 13,524 patients (1,864 immigrant and 11,660 native). The immigrants were younger (45 ± 12 vs. 54 ± 16 years, p < 0.001), had been diagnosed younger (31 ± 12 vs. 36 ± 15 years, p < 0.001), and had a shorter disease duration (14 ± 7 vs. 18 ± 8 years, p < 0.001) than native patients. Family history of IBD (9 vs. 14%, p < 0.001) and smoking (30 vs. 40%, p < 0.001) were more frequent among native patients. The most prevalent ethnic groups among immigrants were Caucasian (41.5%), followed by Latin American (30.8%), Arab (18.3%), and Asian (6.7%). Extraintestinal manifestations, mainly musculoskeletal affections, were more frequent in immigrants (19 vs. 11%, p < 0.001). Use of biologics, mainly anti-TNF, was greater in immigrants (36 vs. 29%, p < 0.001). The risk of having extraintestinal manifestations [OR: 2.23 (1.92-2.58, p < 0.001)] and using biologics [OR: 1.13 (1.0-1.26, p = 0.042)] was independently associated with immigrant status in the multivariate analyses. CONCLUSIONS: Compared with native-born patients, first-generation-immigrant IBD patients in Spain were younger at disease onset and showed an increased risk of having extraintestinal manifestations and using biologics. Our study suggests a featured phenotype of immigrant IBD patients in Spain, and constitutes a new landmark in the epidemiological characterization of immigrant IBD populations in Southern Europe.
RESUMO
BACKGROUND AND AIMS: Crohn's disease [CD] can develop penetrating complications at any time during the disease course. Enterocutaneous fistulae [ECF] are disease-related complications with an important impact on quality of life. Our aim was to describe the outcomes of this complication, including its medical and/or surgical management and their temporal trends. The primary endpoint was fistula closure, defined as the absence of drainage, with no new abscess or surgery, over the preceding 6 months. METHODS: Clinical information from all adult patients with CD and at least one ECF-excluding perianal fistulae-were identified from the prospectively-maintained ENEIDA registry. All additional information regarding treatment for this complication was retrospectively reviewed. RESULTS: A total of 301 ECF in 286 patients [January 1970-September 2020] were analysed out of 30 088 records. These lesions were mostly located in the ileum [67%] and they had a median of one external opening [range 1-10]. After a median follow-up of 146 months (interquartile range [IQR], 69-233), 69% of patients underwent surgery. Fistula closure was achieved in 84%, mostly after surgery, and fistula recurrence was uncommon [13%]. Spontaneous and low-output fistulae were associated with higher closure rates (hazard ratio [HR] 1.51, 95% confidence interval [CI] 1.17-1.93, pâ =â 0.001, and HR 1.49, 95% CI 1.07-2.06, pâ =â 0.03, respectively); this was obtained more frequently with medical therapy since biologics have been available. CONCLUSIONS: ECF complicating CD are rare but entail a high burden of medical and surgical resources. Closure rates are high, usually after surgery, and fistula recurrence is uncommon. A significant proportion of patients receiving medical therapy can achieve fistula closure.

BACKGROUND AND AIMS: Immunomediated adverse events [IAEs] are the most frequently reported infliximab [IFX]-related adverse events. Combination therapy may reduce their incidence, although this strategy is not recommended in elderly patients. We aimed to compare the rates of IFX-related IAEs and loss of response [LOR] in elderly and younger patients. METHODS: Adult patients in the ENEIDA registry who had received a first course of IFX therapy were identified and grouped into two cohorts regarding age at the beginning of treatment [over 60 years and between 18 and 50 years]. The rates of IAEs and LOR were compared. RESULTS: In total, 939 patients [12%] who started IFX over 60 years of age and 6844 [88%] below 50 years of age were included. Elderly patients presented a higher proportion of AEs related to IFX [23.2% vs 19%; p = 0.002], infections [7.1% vs 4.3%; p < 0.001] and neoplasms [2.2% vs 0.5%; p < 0.001]. In contrast, the rates of IAEs [14.8% vs 14.8%; p = 0.999], infusion reactions [8.1% vs 8.1%; p = 0.989], late hypersensitivity [1.3% vs 1.2%; p = 0.895], paradoxical psoriasis [1% vs 1.5%; p = 0.187] and drug-induced lupus erythematosus [0.6% vs 0.7%; p = 0.947] were similar in elderly and younger patients. LOR rates were also similar between the two groups [20.5% vs 19.3%; p = 0.438]. In the logistic regression analysis, IFX monotherapy, extraintestinal manifestations and female gender were the only risk factors for IAEs, whereas IFX monotherapy, extraintestinal manifestations and Crohn's disease were risk factors for LOR. CONCLUSIONS: Elderly patients with inflammatory bowel disease have a similar risk of developing IFX-related IAEs and LOR to that of younger patients.

BACKGROUND: The efficacy of infliximab therapy in patients with Crohn's disease (CD) is unknown beyond 12 months. For patients who lose their initial response, consideration can be given to dose "escalation" to regain therapeutic benefit. AIM: Our primary goal was to evaluate the long-term durability of maintenance infliximab treatment. The secondary goals were to identify potential predictors of loss of infliximab efficacy, to evaluate the response to infliximab escalation, and the safety of the treatment with infliximab with and without escalation of dose. METHODS: CD patients treated with infliximab with response to an induction regimen were evaluated. Maintenance of long-term response was estimated using Kaplan-Meier analysis. The effect of specific variables was calculated using logistic regression analysis. Efficacy of dose escalation in patients who lose response to infliximab was analyzed. RESULTS: Three hundred and nine CD patients were included. The mean follow-up time with infliximab treatment was 41 months, and the majority (95%) were on concomitant immunosuppressive therapy. The annual risk of loss of response to infliximab was 12% per patient-year of treatment. After loss of response, 41% of patients were managed with infliximab therapy escalation. After the first intensified dose, 56% of patients achieved remission and 40% partial response. Concurrent immunomodulators enhanced and smoking decreased the proportion of patients who maintained response (P<0.05). CONCLUSIONS: A relevant proportion of CD patients on long-term infliximab treatment loss response. After loss of response, a high proportion of these patients initially respond to infliximab dose escalation. Concurrent immunomodulators may increase and smoking may decrease maintenance of response.

BACKGROUND: Crohn's disease (CD) with upper gastrointestinal involvement (UGI) may have a more aggressive and refractory course. However, evidence on this phenotype of patients is scarce. AIMS: To identify the clinical characteristics, therapeutic requirements and complications associated with UGI in CD METHODS: Nationwide study of cases (UGI, UGI plus ileal/ileocolonic involvement) paired with controls (ileal/ileocolonic involvement) from the ENEIDA registry. Cases were matched to 2 controls by year of diagnosis ± 2.5 years. Patients with exclusive/predominant colonic location or complex perianal fistula were excluded. RESULTS: Of 24 738 patients with CD in the ENEIDA registry, we identified 4058 with UGI (16% of the total CD cohort). Finally, 854 cases and 1708 controls were included. Cases were independently associated to extensive involvement (OR 2.7 [2.2-3.3], P < 0.0001), strictures [OR 1.8 (1.5-2.2), P < 0.0001], chronic iron deficiency anaemia [OR 2.2 (1.3-3.2), P < 0.001] and use of second-line biologics [OR 1.7 (1.1-2.6), P = 0.021]. The median stricture-free time was 14 years (95% CI, 12-16) for cases vs 21 years (95% CI, 19-23) for controls (P < 0.0001). Cases with isolated UGI compared to UGI plus ileal/ileocolonic more frequently had localised disease [OR 0.5(0.3-0.8), P = 0.003] and underwent more endoscopic stricture dilations [OR 2.7(1.3-5.4), P = 0.006]. CONCLUSIONS: The largest cohort of patients with CD and UGI provides information on the natural history of this particular phenotype. Increased awareness of the clinical picture and therapeutic requirements of these patients could lead to earlier diagnosis and treatment of upper gastrointestinal lesions, preventing the structural damage frequently seen in these patients at diagnosis and during follow-up.

BACKGROUND: The immune response involved in the pathogenesis of Inflammatory Bowel Disease (IBD) may be present years before the diagnosis, but the characteristics of the disease during the preclinical period have been scarcely investigated. AIM: To describe the microscopic findings of preclinical IBD and its relationship with the natural history of the disease. METHODS: Medical records from all patients with an incidental diagnosis of IBD during a screening colonoscopy were included in this multicentric and retrospective study. We assessed 15 histologic items in the biopsy samples at diagnosis, and the Geboes score was calculated in patients with Ulcerative Colitis (UC). The main outcome was the development of gastrointestinal symptoms during follow-up. RESULTS: We included 110 patients (79 UC, 24 Crohn's Disease (CD) and 7 with unclassified disease). In UC the most common histologic findings were acute or chronic inflammatory infiltrate and crypt epithelial polymorphs, while in CD we observed acute or chronic neutrophilic infiltrate and epithelial irregularity. Granuloma were only observed in 4% of CD patients. Crypt distortion and the infiltration of neutrophils in the epithelium were associated with a higher risk of developing symptomatic disease. CONCLUSIONS: Preclinical IBD shows specific microscopic findings and they are associated with the progression to symptomatic disease.

Objective: To evaluate the impact of comorbidities and extraintestinal manifestations of inflammatory bowel disease on the response of patients with inflammatory bowel disease to antitumour necrosis factor alpha (anti-TNFα) therapy. Design: Data from 310 patients (194 with Crohn's disease and 116 with ulcerative colitis) treated consecutively with the first anti-TNFα in 24 Spanish hospitals were retrospectively analysed. Univariate and multivariate logistic regression analyses were performed to assess the associations between inflammatory bowel disease comorbidities and extraintestinal manifestations with anti-TNFα treatment outcomes. Key clinical features, such as type of inflammatory bowel disease and concomitant treatments, were included as fixed factors in the model. Results: Multivariate logistic regression analyses (OR, 95% CI) showed that chronic obstructive pulmonary disease (2.67, 1.33 to 5.35) and hepato-pancreato-biliary diseases (1.87, 1.48 to 2.36) were significantly associated with primary non-response to anti-TNFα, as was the use of corticosteroids and the type of inflammatory bowel disease (ulcerative colitis vs Crohn's disease). It was also found that myocardial infarction (3.30, 1.48 to 7.35) and skin disease (2.73, 1.42 to 5.25) were significantly associated with loss of response, along with the use of corticosteroids and the type of inflammatory bowel disease (ulcerative colitis vs Crohn's disease). Conclusions: Our results suggest that the presence of some comorbidities in patients with inflammatory bowel disease, such as chronic obstructive pulmonary disease and myocardial infarction, and of certain extraintestinal manifestations of inflammatory bowel disease, such as hepato-pancreato-biliary conditions and skin diseases, appear to be related to failure to anti-TNFα treatment. Therefore, their presence should be considered when choosing a treatment. Trial registration number: NCT02861118.

BACKGROUND: Tacrolimus is a calcineurin inhibitor commonly used for prophylaxis of rejection in renal and liver transplantation. There are limited but favourable data regarding its possible use in patients with inflammatory bowel disease (IBD). AIMS: To evaluate the efficacy and safety of tacrolimus in patients with IBD in clinical practice. METHODS: We performed a retrospective, multicentre study in 22 centres in Spain. All adult patients who received oral tacrolimus for luminal or perianal IBD were included. Clinical response was assessed by Harvey-Bradshaw index and partial Mayo score after 3 months. Perianal disease was evaluated by fistula drainage assessment. RESULTS: One hundred and forty-three patients were included (mean age 38 years; 51% male; median disease duration 110 months). In ulcerative colitis (UC) (n = 58), the partial Mayo score decreased after 3 months from median 6 to 3 (P = 0.0001), whereas in Crohn's disease (CD) (n = 85), the Harvey-Bradshaw index decreased after 3 months from median 9 to 7 (P = 0.011). In CD patients, blood tacrolimus concentrations during induction (>10 ng/mL vs <10 ng/mL; odds ratio 0.23, 95% CI 0.05-0.87) and the concomitant use of thiopurines (odds ratio 0.18, 95% CI 0.04-0.81) were associated with lower clinical disease activity at 3 months. Of 62 patients with perianal disease, complete closure was observed in 8% (n = 5) of patients with perianal fistulas, with 34% (n = 21) showing partial response. Treatment was maintained for a median of 6 months (IQR, 2-16). After a median clinical follow-up of 24 months (IQR, 15-57), the rate of treatment-related adverse events was 34%, correlating with blood drug concentrations (P = 0.021). Finally, 120 patients (84%) discontinued tacrolimus, usually due to absence or loss of response. Three patients (2%) were subsequently diagnosed with cancer. The overall rate of surgery was 39%, with a 33% colectomy rate in UC. CONCLUSIONS: Tacrolimus shows a clinical benefit in both CD and UC after 3 months of treatment, but its long-term effectiveness and frequent adverse events remain relevant issues in clinical practice.

BACKGROUND: There is limited evidence on the effectiveness of biological therapy in stricturing complications in patients with Crohn's disease. AIM: The study aims to determine the effectiveness of anti-tumor necrosis factor (TNF) agents in Crohn's disease complicated with symptomatic strictures. METHODS: In this multicentric and retrospective study, we included adult patients with symptomatic stricturing Crohn's disease receiving their first anti-TNF therapy, with no previous history of biological, endoscopic or surgical therapy. The effectiveness of the anti-TNF agent was defined as a composite outcome combining steroid-free drug persistence with no use of new biologics or immunomodulators, hospital admission, surgery or endoscopic therapy during follow-up. RESULTS: Overall, 262 patients with Crohn's disease were included (53% male; median disease duration, 35 months, 15% active smokers), who received either infliximab (N = 141, 54%) or adalimumab (N = 121, 46%). The treatment was effective in 87% and 73% of patients after 6 and 12 months, respectively, and continued to be effective in 26% after a median follow-up of 40 months (IQR, 19-85). Nonetheless, 15% and 21% of individuals required surgery after 1 and 2 years, respectively, with an overall surgery rate of 32%. Postoperative complications were identified in 15% of patients, with surgical site infection as the most common. Starting anti-TNF therapy in the first 18 months after the diagnosis of Crohn's disease or the identification of stricturing complications was associated with a higher effectiveness (HR 1.62, 95% CI 1.18-2.22; and HR 1.55, 95% CI 1.1-2.23; respectively). Younger age, lower albumin levels, strictures located in the descending colon, concomitant aminosalicylates use or presence of lymphadenopathy were associated with lower effectiveness. CONCLUSIONS: Anti-TNF agents are effective in approximately a quarter of patients with Crohn's disease and symptomatic intestinal strictures, and 68% of patients are free of surgery after a median of 40 months of follow-up. Early treatment and some potential predictors of response were associated with treatment success in this setting.
