ABSTRACT
BACKGROUND & AIMS: The impact of patient sex on the presentation of inflammatory bowel disease (IBD) has been poorly evaluated. Our aims were to assess potential disparities in IBD phenotype and progression between sexes. METHODS: We performed an observational multicenter study that included patients with Crohn's disease (CD) or ulcerative colitis from the Spanish Estudio Nacional en Enfermedad Inflamatoria intestinal sobre Determinantes genéticos y Ambientales registry. Data extraction was conducted in July 2021. RESULTS: A total of 51,595 patients with IBD were included, 52% were males and 25,947 had CD. The median follow-up period after diagnosis was 9 years in males and 10 years in females. In CD, female sex was an independent risk factor for medium disease onset (age, 17-40 y) (relative risk ratio, 1.45; 95% CI, 1.31-1.62), later disease onset (age, >40 y) (relative risk ratio, 1.55; 95% CI, 1.38-1.73), exclusive colonic involvement (odds ratio, 1.24; 95% CI, 1.14-1.34), inflammatory behavior (odds ratio, 1.14; 95% CI, 1.07-1.21), and extraintestinal manifestations (odds ratio, 1.48; 95% CI, 1.38-1.59). However, female sex was a protective factor for upper gastrointestinal involvement (odds ratio, 0.84; 95% CI, 0.79-0.90), penetrating behavior (odds ratio, 0.76; 95% CI, 0.70-0.82), perianal disease (odds ratio, 0.77; 95% CI, 0.71-0.82), and complications (odds ratio, 0.73; 95% CI, 0.66-0.80). In ulcerative colitis, female sex was an independent risk factor for extraintestinal manifestations (odds ratio, 1.48; 95% CI, 1.26-1.61). However, female sex was an independent protective factor for disease onset from age 40 onward (relative risk ratio, 0.76; 95% CI, 0.66-0.87), left-sided colonic involvement (relative risk ratio, 0.72; 95% CI, 0.67-0.78), extensive colonic involvement (relative risk ratio, 0.59; 95% CI, 0.55-0.64), and abdominal surgery (odds ratio, 0.78; 95% CI, 0.69-0.88). CONCLUSIONS: There is sexual dimorphism in IBD. The patient's sex should be taken into account in the clinical management of the disease.
ABSTRACT
BACKGROUND: Thiopurines are classically used in Crohn's disease (CD). Treatment fails in a proportion of patients either due to adverse events (AE) or lack of efficacy. Increasing use of anti-TNFα biologic drugs may have had impact on thiopurines usage. AIM: To evaluate the evolving use of azathioprine (AZA) monotherapy in the era of biologics. METHODS: The study retrospectively analyzed clinical records of all CD patients who started treatment with AZA monotherapy at our center since 1990. Dates of starting AZA and treatment failure (TF) were collected. We defined AZA TF if it was withdrawn due to lack of efficacy or AE, or biologics were added. RESULTS: A total of 383 patients were included: 46.5% were males and mean age was 31 (range 17-84) years. Median follow-up was 43 (range 0.2-289) months. Overall, 147 patients (38%) experienced TF. Median cumulative survival time of AZA was 126 (95% CI 105-147) months. Proportion of patients with AZA TF increased along time: 7 patients in 1990-1995 (4.7% of all TF); 8 in 1996-2000 (5.4%); 22 in 2001-2005(15%); 41 in 2006-2010 (28%); 69 in 2011-2014 (47%) (p = 0.04). 7%, 21%, 4%, 45%, and 33.3% of patients moved to biologics in each period, respectively (χ2 = 13.07; p < 0.05). Seventy-four patients (18.4%) stopped AZA due to AE, and 73(19%) due to lack of efficacy. Regarding AZA indication, prevention of postoperative recurrence obtained better results than steroid dependency (p = 0.001); perianal fistulizing CD predicted poorer outcomes (p = 0.002). CONCLUSION: An important proportion of CD patients under AZA monotherapy experienced TF in our experience. Although AZA monotherapy remains useful for CD in the era of biologics, current clinical practice is shifting to anti-TNFα biologic drugs in an increasing proportion of patients.

In 2013, the European Medicines Agency (EMA) approved the biosimilar infliximab (CT-P13) for the full range of indications of the originator product, based on data from two trials conducted in rheumatoid arthritis and ankylosing spondylitis. The same year, our Society published a position statement that was later reviewed.

INTRODUCTION: iron deficiency anemia is a common and very relevant manifestation of inflammatory bowel disease (IBD). Although clinical practice guidelines have been published and updated on this subject, the management in the daily practice of this complication is far from optimal. OBJECTIVE: to determine the actual management, needs and limitations of anemia in IBD by means of a survey of gastroenterology specialists. MATERIAL AND METHODS: a self-administered telematic survey was carried out between April and May 2017 and was sent to SEPD members. The survey included four sections: participant demographics, monitoring, treatment and limitations/needs. RESULTS: a total of 122 evaluable surveys were received from all Spanish autonomous communities. Iron deficiency anemia is considered as a frequent manifestation of IBD and is monitored in all patients via the measurement of hemoglobin and ferritin. In the case of anemia, the survey respondents found it necessary to rule out the presence of IBD activity. However, only 14.8% prescribed intravenous iron when IBD was active. The required dose of intravenous iron is mainly calculated according to patient needs but only 33.1% of clinicians infused doses of 1 g or more. CONCLUSIONS: the "Gestiona Hierro EII" survey on the management of anemia in IBD demonstrated a high quality of care, even though some aspects need to be improved. These included the prescription of intravenous iron for patients with disease activity, the use of high-dose intravenous iron and the implementation of algorithms into clinical practice.

BACKGROUND: The exploration of clinically relevant information in the free text of electronic health records (EHRs) holds the potential to positively impact clinical practice as well as knowledge regarding Crohn disease (CD), an inflammatory bowel disease that may affect any segment of the gastrointestinal tract. The EHRead technology, a clinical natural language processing (cNLP) system, was designed to detect and extract clinical information from narratives in the clinical notes contained in EHRs. OBJECTIVE: The aim of this study is to validate the performance of the EHRead technology in identifying information of patients with CD. METHODS: We used the EHRead technology to explore and extract CD-related clinical information from EHRs. To validate this tool, we compared the output of the EHRead technology with a manually curated gold standard to assess the quality of our cNLP system in detecting records containing any reference to CD and its related variables. RESULTS: The validation metrics for the main variable (CD) were a precision of 0.88, a recall of 0.98, and an F1 score of 0.93. Regarding the secondary variables, we obtained a precision of 0.91, a recall of 0.71, and an F1 score of 0.80 for CD flare, while for the variable vedolizumab (treatment), a precision, recall, and F1 score of 0.86, 0.94, and 0.90 were obtained, respectively. CONCLUSIONS: This evaluation demonstrates the ability of the EHRead technology to identify patients with CD and their related variables from the free text of EHRs. To the best of our knowledge, this study is the first to use a cNLP system for the identification of CD in EHRs written in Spanish.

ABSTRACT
(1) Aims: To assess the incidence of inflammatory bowel disease (IBD) in Spain, to describe the main epidemiological and clinical characteristics at diagnosis and the evolution of the disease, and to explore the use of drug treatments. (2) Methods: Prospective, population-based nationwide registry. Adult patients diagnosed with IBD-Crohn's disease (CD), ulcerative colitis (UC) or IBD unclassified (IBD-U)-during 2017 in Spain were included and were followed-up for 1 year. (3) Results: We identified 3611 incident cases of IBD diagnosed during 2017 in 108 hospitals covering over 22 million inhabitants. The overall incidence (cases/100,000 person-years) was 16 for IBD, 7.5 for CD, 8 for UC, and 0.5 for IBD-U; 53% of patients were male and median age was 43 years (interquartile range = 31-56 years). During a median 12-month follow-up, 34% of patients were treated with systemic steroids, 25% with immunomodulators, 15% with biologics and 5.6% underwent surgery. The percentage of patients under these treatments was significantly higher in CD than UC and IBD-U. Use of systemic steroids and biologics was significantly higher in hospitals with high resources. In total, 28% of patients were hospitalized (35% CD and 22% UC patients, p < 0.01). (4) Conclusion: The incidence of IBD in Spain is rather high and similar to that reported in Northern Europe. IBD patients require substantial therapeutic resources, which are greater in CD and in hospitals with high resources, and much higher than previously reported. One third of patients are hospitalized in the first year after diagnosis and a relevant proportion undergo surgery.
ABSTRACT
AIM: To evaluate the effectiveness and safety of tofacitinib in ulcerative colitis [UC] in real life. METHODS: Patients from the prospectively maintained ENEIDA registry and treated with tofacitinib due to active UC were included. Clinical activity and effectiveness were defined based on Partial Mayo Score [PMS]. Short-term response/remission was assessed at Weeks 4, 8, and 16. RESULTS: A total of 113 patients were included. They were exposed to tofacitinib for a median time of 44 weeks. Response and remission at Week 8 were 60% and 31%, respectively. In multivariate analysis, higher PMS at Week 4 (odds ratio [OR]â =â 0].2; 95% confidence interval [CI]â =â 0].1-0.4) was the only variable associated with lower likelihood of achieving remission at Week 8. Higher PMS at Week 4 [ORâ =â 0.5; 95% CIâ =â 0.3-0.7] and higher PMS at Week 8 [ORâ =â 0.2; 95% CIâ =â 0.1-0.5] were associated with lower probability of achieving remission at Week 16. A total of 45 patients [40%] discontinued tofacitinib over time. Higher PMS at Week 8 was the only factor associated with higher tofacitinib discontinuation [hazard ratioâ =â 1.5; 95% CIâ =â 1.3-1.6]. A total of 34 patients had remission at Week 8; of these, 65% had relapsed 52 weeks after achieving remission; the dose was increased to 10 mg/12 h in nine patients, and five of them reached remission again. Seventeen patients had adverse events. CONCLUSIONS: Tofacitinib is effective and safe in UC patients in real practice, even in a highly refractory cohort. A relevant proportion of patients discontinue the drug over time, mainly due to primary failure.

BACKGROUND: In APPRECIA trial, Crohn's disease (CD) patients undergoing intestinal resection were randomized to postoperative adalimumab (ADA) or azathioprine (AZA). AIMS: To evaluate health-related quality of life (HRQoL) in APPRECIA trial. METHODS: HRQoL was evaluated using disease-specific shortened Spanish version of the IBDQ (SIBDQ-9) and generic European Quality of Life-5 Dimensions (EQ-5D) questionnaires, completed at baseline and at weeks 24 and 52. RESULTS: Sixty-one patients (37 ADA and 24 AZA) had evaluable data for HRQoL. Patients treated with ADA or AZA had significant improvement from baseline to weeks 24 and 52 in SIBDQ-9 and EQ-5D (pâ¯<â¯0.001 and pâ¯≤â¯0.006 for all comparisons, respectively). There were no differences between treatment arms in mean change in SIBDQ-9 and EQ-5D at weeks 24 and 52 vs baseline. Only patients without endoscopic recurrence had significant improvement in SIBDQ-9 (pâ¯<â¯0.001) and EQ-5D (pâ¯<â¯0.001) at week 52. At week 52, there was a high to moderate negative correlation between CDAI score with SIBDQ-9 score (Pearson's r: -0.768) and with EQ-5D index (r: -0.644). CONCLUSION: HRQoL improved after intestinal resection in CD, irrespective of the postoperative therapy used (ADA or AZA). Outcomes in HRQoL were associated with prevention of endoscopic recurrence, since improvements in HRQoL were only significant in patients with endoscopic remission at 1 year.

BACKGROUND AND AIMS: Postoperative recurrence of Crohn's disease [POR-CD] is almost certain if no prophylaxis is administered. Evidence for optimal treatment is lacking. Our aim was to compare the efficacy of adalimumab [ADA] and azathioprine [AZA] in this setting. METHODS: We performed a phase 3, 52-week, multicentre, randomised, superiority study [APPRECIA], in which patients with ileocolonic resection were randomised either to ADA 160-80-40 mg subcutaneously [SC] or AZA 2.5 mg/kg/day, both associated with metronidazole. The primary endpoint was endoscopic recurrence at 1 year [Rutgeerts i2b, i3, i4], as evaluated by a blinded central reader. RESULTS: We recruited 91 patients [median age 35.0 years, disease duration 6.0 years, 23.8% smokers, 7.1% previous resections]. The study drugs were administered to 84 patients. Treatment was discontinued owing to adverse events in 11 patients [13.1%]. Discontinuation was significantly less frequent in the ADA [4.4%] than in the AZA group [23.2%] (dif.: 18.6% [95% CI 4.1-33.2], p = 0.011). According to the intention-to-treat analysis, therapy failed in 23/39 patients in the AZA group [59%] and 19/45 patients in the ADA group [42.2%] [p = 0.12]. In the per-protocol analysis [61 patients with centrally evaluable images], recurrence was recorded in 8/24 [33.3%] patients in the AZA and 11/37 [29.7%] in the ADA group [p = 0.76]. No statistically significant differences between the groups were found for recurrence in magnetic resonance images, biological markers of activity, surgical procedures, or hospital admissions. CONCLUSIONS: ADA has not demonstrated a better efficacy than AZA [both associated with metronidazole] for prophylaxis of POR-CD in an unselected population, although tolerance to ADA is significantly better.
