Resumen La pandemia COVID-19 ha supuesto un cambio cualitativo en el modo de atender a los pacientes en consultas ambulatorias. La necesidad de toma de medidas de aislamiento social como prevencion para el contagio por el SARS-CoV-2 ha obligado al uso de consultas telematicas y telefonicas en la mayoria de unidades medicas y quirurgicas. La especialidad de Aparato Digestivo, por las caracteristicas de sus pacientes y el apoyo frecuente en tecnicas complementarias para el diagnostico, es especialmente adecuada para realizar consultas no presenciales. En este documento se plantean una serie de recomendaciones que pueden servir como guia para el establecimiento o mejora de consultas no presenciales de Medicina Digestiva.

Background The management of inflammatory bowel disease (IBD) has substantially changed in the last decades, both in relation to medical and surgical treatments. Aims Principal: To know the rate of surgery in a newly diagnosed IBD cohort within the first year after diagnosis. Secondary: To describe the type of surgeries and indications in this cohort, and to identify predictive factors for surgery (focused on intestinal resection) in these patients. Methods Prospective, population-based nationwide registry. Adult patients diagnosed with IBD -Crohn’s disease (CD) and ulcerative colitis (UC)- during 2017 in Spain were included and were followed-up for 1 year. Kaplan-Meier curves were used to calculate the rate of surgery. In patients with intestinal resections, only medical treatments before surgery were considered. Predictive factors for surgery were identified by Cox-regression analysis. Results 3,454 patients (1,647 CD and 1,807 UC) were included (table 1). The incidence rate for surgery was significantly higher among CD patients (figure 1). A total of 197 patients (6%) underwent surgery within the first 12 months: 126 (64%) intestinal resections, and 71 (36%) perianal surgeries. Fifty-seven percent of intestinal resections were urgent, and 43% elective. The main indications for intestinal resections were: intestinal obstruction in 37%, abscess/fistula in 27%, perforation/acute abdomen in 25%, and refractoriness to medical treatment in 18% of cases. A total of 174 CD patients (10.6%) underwent surgery ¾61% intestinal resections and 39% perianal. Twenty-three UC patients (1.3%) were operated on; the number of surgeries in UC was too low to identify predictive factors. In CD patients, to have been treated with thiopurines [Hazard ratio (HR)=0.2, 95% confidence interval (CI)=0.1–0.3) was associated with lower likelihood of intestinal resection. Disease behaviour at diagnosis [stricturing vs. inflammatory (HR=6.5, 95%CI=4–10) and fistulising vs. inflammatory (HR=13, 95%CI=9–21)] was associated with the risk of intestinal resection. Biologic treatment was not associated with the likelihood of intestinal resection (figure 2). Conclusion Six percent of IBD patients undergo surgery within the first year of diagnosis, being higher in CD (11%) than in UC (1.3%). Sixty percent of intestinal resections are urgent procedures. The risk of surgery is increased in CD patients with fistulising and stricturing behaviour. Thiopurine, but not biologic treatment, is associated with lower risk of surgery.

Altres ajuts: Takeda Farmacéutica España S.A. Background: Anti-TNFα represent one of the main treatment approaches for the management of inflammatory bowel diseases (IBD). Therefore,the evaluation of their treatment patterns over time provides valuable insights about the clinical value of therapies and associated costs. Aims: To assess the treatment patterns with the first anti-TNFα in IBD. Methods: Retrospective, observational study. Results: 310 IBD patients were analyzed along a 5-year follow-up period. 56.2% of Crohn's disease (CD) patients started with adalimumab (ADA), while 43.8% started with infliximab (IFX). 12.9% of ulcerative colitis (UC) patients initiated with ADA, while 87.1% initiated with IFX. Treatment intensification was required in 28.9% of CD and 37.1% of UC patients. Median time to treatment intensification was shorter in UC than in CD (5.3 vs. 14.3 months; p = 0.028). Treatment discontinuation due to reasons other than remission were observed in 40.7% of CD and 40.5% of UC patients, although, in UC patients there was a trend to lower discontinuation rates with IFX (36.6%) than with ADA (66.7%). Loss of response accounted for approximately one-third of discontinuations, in both CD and UC. Conclusions: Around one-third of IBD biologic-naive patients treated with an anti-TNFα required treatment intensification (earlier in UC) and around 40% discontinued the anti-TNFα due to inappropriate disease control.

ObjectiveTo 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.DesignData 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.ResultsMultivariate 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).ConclusionsOur 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 numberNCT02861118.

Background: Despite the continuous adaptation of eHealth systems for patients with inflammatory bowel disease (IBD), a significant disconnection persists between users and developers. Since non-adherence remains high, it is necessary to better understand the patients&rsquo, perspective on telemonitoring for IBD. Accordingly, this study aimed to adapt the TECCU telemonitoring app to the preferences and needs of IBD patients. Methods: A qualitative study was carried out using successive focus groups of IBD patients. Meetings were audio-recorded and a thematic analysis was employed until data saturation was achieved. The first group included patients who had used the TECCU App in a pilot clinical trial, and subsequent meetings included patients with Crohn's disease and ulcerative colitis recruited from the Spanish Confederation of patient associations. The information collected at each meeting guided consecutive changes to the platform. Results: Data saturation was reached after three focus groups involving a total of 18 patients. Three main themes emerged: (1) platform usability, (2) the communication process, and (3) platform content. All participants indicated that TECCU is easy to use, permitting continuous and personalized feedback. According to patients&acute, perspectives, the platform was adapted to foster a flexible follow-up and shared decision-making using open and safe communication networks. Many participants appreciated the educational elements and, consequently, the app was connected to reliable and continuously updated webpages. Conclusions: IBD patients valued the usability and personalized monitoring offered by the TECCU App. Improvements in the messaging system and continuously updated educational content were introduced to address patients&acute, needs and favor their engagement.

Resumen Las tiopurinas (azatioprina y mercaptopurina) se usan frecuentemente en pacientes con enfermedad inflamatoria intestinal. En este documento, revisaremos sus principales indicaciones, asi como aspectos practicos de seguridad, eficacia y modo de empleo. Sus usos principales son el mantenimiento de la remision en la enfermedad corticodependiente o tras el control de un brote grave de colitis ulcerosa con ciclosporina, la prevencion de la recurrencia posquirurgica en enfermedad de Crohn y el empleo en terapia combinada junto con biologicos. El 30-40% de pacientes no respondera al tratamiento y un 10-20% no tolerara el tratamiento por efectos adversos. Antes de iniciarlas, se recomienda evaluar el estado de inmunizacion frente a ciertas infecciones; la determinacion previa de la actividad de la tiopurina·metiltransferasa (TPMT) no es imprescindible, pero permite mayor seguridad inicial. La dosis adecuada es de 2,5 mg/kg/dia para azatioprina y de 1,5 mg/kg/dia para mercaptopurina. Algunos efectos adversos son idiosincrasicos (intolerancia digestiva, pancreatitis, fiebre, artromialgias, exantema y algunos casos de hepatotoxicidad). Otros son dosis-dependientes (mielotoxicidad y otros tipos de hepatotoxicidad) y su vigilancia debe mantenerse mientras dure el tratamiento. Si son ineficaces o aparecen efectos adversos, puede recurrirse al cambio de tiopurina, la reduccion de dosis, combinar dosis bajas de azatioprina con alopurinol y determinar metabolitos antes de descartar su uso. Los tumores de piel distintos al melanoma, los linfomas y los tumores del tracto urinario se han relacionado con su administracion. Las tiopurinas son farmacos seguros en la concepcion, gestacion y lactancia.

Background COVID-19 pandemic increased medical services demand aside from interrupting daily clinical practice for other diseases such as Inflammatory Bowel Disease (IBD). Here we present the results of a survey to gain the perception of IBD specialists in their patient-management using telemedicine in their daily practice. Methods This was an observational survey study among physicians focused on IBD (gastroenterologist, surgeons, and pediatricians) members of the Spanish Working Group on Crohn’s Disease and Ulcerative Colitis (GETECCU), the Spanish Association of Gastroenterology (AEG), and the Spanish Association of Coloproctology (AECP), regarding changes of management of IBD patients. Results We received a total of 269 responses to the survey (from May to June 2020). Before the pandemic, nearly all the respondents reported performing very frequently their visits face-to-face (n=251, 93.3%) while, during the pandemic, the telephone visits were the most frequent visits performed (n=138, 51,3%). Regarding communication difficulties, 157 (58.4%) respondents reported the impossibility of performing a proper examination as the most relevant issue. Also, 114 (42.4%) respondents considered remote visits more time-consuming than face-to-face visits. Most gastroenterologists (n=188, 83.2%) considered patients with active perianal disease in special need of face-to-face consultation and more than half of the surgeons (n=35, 50.7%) reported having performed an immediate postoperative follow-up remotely. Conclusion Most IBD units have implemented remote visits during the pandemic, but most professionals found them more time-consuming and unsuitable for some disease profiles. Therefore, there is a need for the development of better telemedicine systems that can meet professionals’ and patients′ requirements.

Background The urinary metabolome of patients with Crohn’s disease (CD) differs significantly from healthy subjects and, among other features, reflects the specific gut dysbiosis affecting these patients. However, most of the studies included established and treated CD patients. Our aim was to characterize the urinary metabolome of onset and treatment-naïve CD patients and to identify the metabolic profile related to the different CD clinical classifications. Methods Patients newly diagnosed with CD (n=131) were prospectively included. Control healthy subjects (HC, n=338) were recruited among the general population and matched for sex, age and BMI to the IBD subjects. Fasting urine was obtained before starting any treatment. Metabolomic analysis was performed by proton nuclear magnetic resonance (1H NMR). We performed a comparative assessment of the urinary metabolome profile using a linear regression model for each metabolite, including sex, age, BMI, and smoking habit as covariates to control for confounding. The different subgroup comparisons within CD were made as follows: (1) CD; (2) CD location (Montreal Classification): L1 (ileal) + L4 (ileal and upper-intestinal), L2 (colonic) and L3 (ileocolonic); (3) endoscopic CD activity: 0, 1, 2 and 3; and (4) CD phenotype: B1 (inflammatory), B2 (stricturing) and B3 (penetrating), versus HC. In addition, data analysis was carried out using partial least squares-discriminate analysis (PLS-DA) to determine class membership based on distinct metabolomic profile. Results The primary characteristics of the CD patients and HC are shown in Table 1. Several metabolites were identified to be differently abundant in each group (Table 2). These metabolites are involved in relevant processes related to energy and aminoacids metabolism, and also include gut-derived metabolites. The PLS-DA model separated patients within the different clinical subgroups (Figures 1–4). Figures 1–4(b) show the main metabolites involved in each group separation. Many of these metabolites are in accordance with the differential metabolites obtained using the univariate analysis (Table 2), showing the potential of this approach to group CD patients and to identify potential biomarkers. Conclusion Analysis of urinary metabolites can help to understand the etiopathological mechanisms in CD. It has the potential to provide a non-invasive means of diagnosing CD, and can differentiate between CD clinical expressions.

Background Ustekinumab (UST) intensification during Crohn’s Disease (CD) treatment is becoming common in clinical practice. Little is known about early intensification maintenance regimens and their drug levels utility in discriminating CD-response and the need for further intensification. We aim to analyze UST levels’ evolution in an intensified maintenance regimen, their capacity to discriminate response according to inflammatory parameters and indicate the need for further intensification. Methods This is a retrospective study with 43 moderate/severe active CD patients (Harvey-Bradshaw Index [HBI] ≥4 and Fecal Calprotectin [FC] >250 µg/g) who received UST induction treatment (induction dose of 6mg/kg IV, plus dose of 90mg SC at week 8). Patients received maintenance treatment (90mg SC/8 weeks) and were followed for 52 weeks. They were classified according to the response obtained at the first year in responders (R), HBI 250µg/g; and intensification group (IG), partially responders that needed UST intensification to every 4 weeks. HBI, FC, C-Reactive Protein (CRP), and UST levels data were collected at baseline (w0), week 8 (w8), week 16 (w16), and 52 weeks (w52) of maintenance. IG was followed 12–26 weeks after intensification (aI). Results Half of the patients (48.8%) were male. Most of them (97.7%) have received previous anti-TNF-α treatment (53.49% ≥2 anti-TNF-α). Patients’ median age at the moment of starting UST was 51 (37.5, 58.5) years. Median disease duration was 11 (7.5, 23) years. Location of disease was ileal in 30% of patients and ileocolic in 53%. One-third of patients suffered perianal disease, and 41 % were smokers. The only demographic factor associated with non-response was ileocolic location. Table 1 shows the evolution of inflammatory parameters and UST levels according to the response. A Pearson correlation (r=0.62) between higher FC drop (baseline-w16) and higher drug levels at w16 was observed. The evolution of biological markers discriminates NR during induction; however, neither biological markers nor UST level can distinguish between R and those who will need intensification. R shows higher UST levels at w52 compared to IG. IG showed a significant increase of UST levels (mean of 5.39 points) and a substantial drop of FC and HBI (mean of 115.62 and 2.27 points, respectively) after intensification. Those patients reported clinical improvement; however, they could not reach a FC Conclusion FC drop-slope is associated with higher levels of UST at the end of induction. UST levels at w52 are useful for discriminating patients who will benefit from UST intensification every 4 weeks.

Inflammatory bowel disease (IBD) is a chronic and relapsing disorder with significant medical, social and financial impacts. IBD patients require continuous follow-up, and healthcare resource use in this context increases over time. In the last decade, telemedicine has influenced the treatment of chronic diseases like IBD via the application of information and communication technologies to provide healthcare services remotely. Telemedicine and its various applications (telemanagement, teleconsulting and tele-education) enable closer follow-up and provide education resources that promote patient empowerment, encouraging treatment optimisation over the entire course of the disease. We describe the impact of using telemedicine on IBD health outcomes and discuss the limitations of implementing these systems in the real-life management of IBD patients.

Background: Little is known about the association between the pharmacokinetic features of adalimumab (ADL) and disease outcome in patients with inflammatory bowel disease (IBD). Aims: To assess the association between random serum ADL levels and clinical or biochemical remission with clinical decision making in daily practice according to these levels; and to determine the cutoff value for successful dose reduction in patients with IBD treated with ADL. Methods: We conducted a prospective observational study of patients with IBD who received long-term maintenance therapy with ADL. Results: Data were available for 157 serum samples from 87 patients. Serum ADL levels were associated with clinical remission: median 9.2 versus 6.0 mu g/mL for patients with Crohn's disease with active disease (P = 0.009) and 14.4 versus 5.2 mg/mL in patients with ulcerative colitis with active disease (P = 0.002). Serum ADL levels were 9.2 mg/mL for patients with a normal C-reactive protein value (

Background Although electronic health interventions are considered safe and efficient, evidence regarding the cost-effectiveness of telemonitoring in inflammatory bowel disease is lacking. Objective We aimed to evaluate the cost-effectiveness and cost-utility of the Telemonitorización de la Enfermedad de Crohn y Colitis Ulcerosa (Telemonitoring of Crohn’s Disease and Ulcerative Colitis [TECCU]) Web platform (G_TECCU intervention group) for telemonitoring complex inflammatory bowel disease, compared with standard care (G_control) and nurse-assisted telephone care (G_NT intervention group). Methods We analyzed cost-effectiveness from a societal perspective by comparing the 3 follow-up methods used in a previous 24-week randomized controlled trial, conducted at a tertiary university hospital in Spain. Patients with inflammatory bowel disease who initiated immunosuppressants or biologic agents, or both, to control inflammatory activity were recruited consecutively. Data on the effects on disease activity (using clinical indexes) and quality-adjusted life-years (using the EuroQol 5 dimensions questionnaire) were collected. We calculated the costs of health care, equipment, and patients’ productivity and social activity impairment. We compared the mean costs per patient, utilities, and bootstrapped differences. Results We included 63 patients (21 patients per group). TECCU saved €1005 (US $1100) per additional patient in remission compared with G_control (95% CI €–13,518 to 3137; US $–14,798 to 3434), with a 79.96% probability of being more effective at lower costs. Compared with G_NT, TECCU saved €2250 (US $2463) per additional patient in remission (95% CI €–15,363 to 11,086; US $–16,817 to 12,135), and G_NT saved €538 (US $589) compared with G_control (95% CI €–6475 to 5303; US $–7088 to 5805). G_TECCU and G_NT showed an 84% and 67% probability, respectively, of producing a cost saving per additional quality-adjusted life-year (QALY) compared with G_control, considering those simulations that involved negative incremental QALYs as well. Conclusions There is a high probability that the TECCU Web platform is more cost-effective than standard and telephone care in the short term. Further research considering larger cohorts and longer time horizons is required.

Background: The reported efficacy of telemedicine in patients with inflammatory bowel disease (IBD) is inconsistent among studies, and data for complex IBD are lacking. Objective: We aimed to evaluate the impact of remote monitoring using a Web system—Telemonitorizacion de la Enfermedad de Crohn y Colitis Ulcerosa or Telemonitoring of Crohn’s Disease and Ulcerative Colitis (TECCU)—as compared to standard care and telephone care on health outcomes and health care in patients with complex IBD. Methods: We performed a 3-arm randomized controlled trial. Adult patients with IBD who received immunosuppressants and biological agents were recruited from the IBD Unit of a tertiary university hospital. The patients were randomized into groups to receive remote monitoring (G_TECCU), nurse-assisted telephone care (G_NT), or standard care with in-person visits (G_control). All patients completed the study visits at baseline and at 12 and 24 weeks in addition to each type of intervention. The primary outcome was the percentage of patients in remission at 24 weeks. Secondary health outcomes were quality of life, medication adherence, adverse effects, satisfaction, and social activities. Data on the number of outpatient visits and telephone calls, emergency visits, hospitalizations, IBD-related surgeries, and corticosteroid courses were also collected. Results: A total of 63 patients were selected (21 patients in each group). During the study, 90.5% (19/21) of patients in G_control, 95.2% (20/21) in G_NT, and 85.7% (18/21) in G_TECCU were compliant to the intervention. After 24 weeks, the percentage of patients in remission was higher in G_TECCU (17/21, 81%) than in G_NT (14/21, 66.7%) and G_control (15/21, 71.4%). A higher improvement in disease activity was observed in G_TECCU than in G_control in terms of the Harvey-Bradshaw/Mayo (odds ratio=0.12, 95% CI=0.003-2.162, P=.19) and Harvey-Bradshaw/Walmsley (odds ratio=0.11, 95% CI=0.004-1.55, P=.13) indexes. Improvement in disease activity was associated with a larger reduction in fecal calprotectin values in G_TECCU compared to G_control (estimated intervention effect: odds ratio=–0.90; 95% CI=–1.96 to 0.16, P=.11). All completers adhered to treatment in G_TECCU. In addition, the quality of life, social activities, and satisfaction improved in all 3 groups. Although the number of outpatient visits and telephone calls was lower in G_TECCU than in G_NT and G_control, the safety profile was similar in all 3 groups. Conclusions: This pilot clinical trial suggests that the TECCU Web-based system is a safe strategy for improving health outcomes in patients with complex IBD and reducing the use of health care resources.

This review article summarizes the evidence about telemedicine applications (e.g., telemonitoring, teleconsulting, and tele-education) in the management of patients with inflammatory bowel disease (IBD), and we aim to give an overview of the acceptance and impact of these interventions on health outcomes. Based on the literature search on "inflammatory bowel disease," "Crohn's disease" and "ulcerative colitis" in combination with "e-health," "telemedicine," and "telemanagement," we selected 58 titles and abstracts published up to June 2014 and searched in PubMed, EMBASE, MEDLINE, Cochrane Database, Web of Science and Conference Proceedings. Titles and abstracts were screened for a set of inclusion criteria: e-health intervention, IBD as the main disease, and a primary study performed. Finally, 16 were included for full reading, data extraction, and critical appraisal of the evaluation. Most studies use telemonitoring (home telemanagement system or web portal) and telecare (real-time telephone and image) as telemedicine applications and assessed the feasibility and acceptance of these systems, adherence to treatment, quality of life, and patient knowledge, particularly in patients with ulcerative colitis. Furthermore, some of these studies evaluated the patients' empowerment, health care costs, and safety of telemonitoring in IBD. In conclusion, the health outcomes of telemedicine applications in IBD suggest that these could be implemented in clinical practice because they are safe and feasible applications that are well accepted by the patient and improve adherence, quality of life, and disease knowledge. Further studies with large sample sizes and complex diseases are needed to confirm these results.

BACKGROUND: Despite the increased use of rescue medical therapies for steroid refractory acute severe ulcerative colitis, mortality related to this entity still remains high. We aimed to assess the mortality and morbidity related to colectomy and their predictive factors in steroid refractory acute severe ulcerative colitis, and to evaluate the changes in mortality rates, complications, indications of colectomy, and the use of rescue therapy over time. METHODS: We performed a multicenter observational study of patients with steroid refractory acute severe ulcerative colitis requiring colectomy, admitted to 23 Spanish hospitals included in the ENEIDA registry (GETECCU) from 1989 to 2014. Independent predictive factors of mortality were assessed by binary logistic regression analysis. Mortality along the study was calculated using the age-standardized rate. RESULTS: During the study period, 429 patients underwent colectomy, presenting an overall mortality rate of 6.3% (range, 0-30%). The main causes of death were infections and post-operative complications. Independent predictive factors of mortality were: age =50 years (OR 23.34; 95% CI: 6.46-84.311; p < 0.0001), undergoing surgery in a secondary care hospital (OR 3.07; 95% CI: 1.01-9.35; p = 0.047), and in an emergency setting (OR 10.47; 95% CI: 1.26-86.55; p = 0.029). Neither the use of rescue medical treatment nor the type of surgical technique used (laparoscopy vs. open laparotomy) influenced mortality. The proportion of patients undergoing surgery in an emergency setting decreased over time (p < 0.0001), whereas the use of rescue medical therapy prior to colectomy progressively increased (p > 0.001). CONCLUSIONS: The mortality rate related to colectomy in steroid refractory acute severe ulcerative colitis varies greatly among hospitals, reinforcing the need for a continuous audit to achieve quality standards. The increasing use of rescue therapy is not associated with a worse outcome and may contribute to reducing emergency surgical interventions and improve outcomes.

Thiopurines (azathioprine and mercaptopurine) are widely used in patients with inflammatory bowel disease. In this paper, we review the main indications for their use, as well as practical aspects on efficacy, safety and method of administration. They are mainly used to maintain remission in steroid-dependent disease or with ciclosporin to control a severe ulcerative colitis flare-up, as well as to prevent postoperative Crohn's disease recurrence, and also in combination therapy with biologics. About 30-40% of patients will not respond to treatment and 10-20% will not tolerate it due to adverse effects. Before they are prescribed, immunisation status against certain infections should be checked. Determination of thiopurine methyltransferase activity (TPMT) is not mandatory but it increases initial safety. The appropriate dose is 2.5mg/kg/day for azathioprine and 1.5mg/kg/day for mercaptopurine. Some adverse effects are idiosyncratic (digestive intolerance, pancreatitis, fever, arthromyalgia, rash and some forms of hepatotoxicity). Others are dose-dependent (myelotoxicity and other types of hepatotoxicity), and their surveillance should never be interrupted during treatment. If therapy fails or adverse effects develop, management can include switching from one thiopurine to the other, reducing the dose, combining low doses of azathioprine with allopurinol and assessing metabolites, before their use is ruled out. Non-melanoma skin cancer, lymphomas and urinary tract tumours have been linked to thiopurine therapy. Thiopurine use is safe during conception, pregnancy and breastfeeding.

Inflammatory bowel disease (IBD) is a chronic and relapsing disorder with significant medical, social and financial impacts. IBD patients require continuous follow-up, and healthcare resource use in this context increases over time. In the last decade, telemedicine has influenced the treatment of chronic diseases like IBD via the application of information and communication technologies to provide healthcare services remotely. Telemedicine and its various applications (telemanagement, teleconsulting and tele-education) enable closer follow-up and provide education resources that promote patient empowerment, encouraging treatment optimisation over the entire course of the disease.

Background Therapeutic drug monitoring (TDM) is used in inflammatory bowel disease to guide dosing of biologics to individualise drug exposure and optimise outcomes. In case of undetectable levels of Adalimumab (levels Methods Since October 13 to August 19, 758 TDM were performed in 260 patients treated with ADA. We selected the patients who had at least a level Results We identified 46 patients with undetectable levels; 12 were excluded. Thirty-four patients were included, 29 (85.3%) with Crohn’s disease and 5 (14.7%) with ulcerative colitis. Ten (29.4%) patients had combined treatment and 17 (50%) had previously received another anti-TNF. In 24 (70.6%) TDM was performed proactively. After detection of levels 5 μg/ml), 12 (60%) in the intensified-patient group and 2 (14.3%) in the group in whom the treatment was not modified. ADA was withdrawn in 13 patients (32.8%) after a mean time of 358 days (SD 258). The ADA maintenance rate (HR=3.88; 95% CI 1.2–12.4; p = 0.02) and the recovery ratio of ADA levels (HR = 6.75; 95% CI 1.1–39, 8; p = 0.03) was higher in the intensified group. Hypoalbuminemia was associated with an earlier withdrawal of ADA (p = 0.03) Conclusion The intensification of ADA in patients with IBD and undetectable plasma concentrations allows recovery of levels and maintenance of the drug in a high percentage of patients. The decision to withdraw treatment in patients with undetectable levels should be individualised.

Background & aims: Disease outcome has been found to be poorer in familial inflammatory bowel disease (IBD) than in sporadic forms, but assessment of phenotypic concordance in familial IBD provided controversial results. We assessed the concordance for disease type and phenotypic features in IBD families. Methods: Patients with familial IBD were identified from the IBD Spanish database ENEIDA. Families in whom at least two members were in the database were selected for concordance analysis (K index). Concordance for type of IBD [Crohn's disease (CD) vs. ulcerative colitis (UC)], as well as for disease extent, localization and behaviour, perianal disease, extraintestinal manifestations, and indicators of severe disease (i.e., need for immunosuppressors, biological agents, and surgery) for those pairs concordant for IBD type, were analyzed. Results: 798 out of 11,905 IBD patients (7%) in ENEIDA had familial history of IBD. Complete data of 107 families (231 patients and 144 consanguineous pairs) were available for concordance analyses. The youngest members of the pairs were diagnosed with IBD at a significantly younger age (p < 0.001) than the oldest ones. Seventy-six percent of pairs matched up for the IBD type (kappa = 0.58; 95%CI: 0.42-0.73, moderate concordance). There was no relevant concordance for any of the phenotypic items assessed in both diseases. Conclusions: Familial IBD is associated with diagnostic anticipation in younger individuals. Familial history does not allow predicting any phenotypic feature other than IBD type. (C) 2013 European Crohn's and Colitis Organisation. Published by Elsevier B.V. All rights reserved.

OBJECTIVES: To determine the efficacy and safety of cyclosporine (CyA) in a large national registry-based population of patients with steroid-refractory (SR) acute severe ulcerative colitis (ASUC) and to establish predictors of efficacy and adverse events. METHODS: Multicenter study of SR-ASUC treated with CyA, based on data from the ENEIDA registry. SR-ASUC patients treated with infliximab (IFX) or sequential rescue therapy (CyA-IFX or IFX-CyA) were used as comparators. RESULTS: Of 740 SR-ASUC patients, 377 received CyA, 131 IFX and 63 sequential rescue therapy. The cumulative colectomy rate was higher in the CyA (24.1%) and sequential therapy (32.7%) than in the IFX group (14.5%; P = 0.01) at 3 months and 5 years. There were no differences in early and late colectomy between CyA and IFX in patients treated after 2005. 62% of patients receiving CyA remained colectomy-free in the long term (median 71 months). There were no differences in mortality between CyA (2.4%), IFX (1.5%) and sequential therapy (0%; P = 0.771). The proportion of patients with serious adverse events (SAEs) was lower in CyA (15.4%) than in IFX treated patients (26.5%) or sequential therapy (33.4%; P < 0.001). This difference in favor of CyA was maintained when only patients treated after 2005 were analyzed. CONCLUSIONS: Treatment with CyA showed a lower rate of SAE and a similar effi cacy to that of IFX thereby supporting the use of either CyA or IFX in SR-ASUC. In addition, the risk-benefi t of sequential CyA-IFX for CyA non-responders is acceptable.

Resumen Introduccion Los fenomenos tromboembolicos venosos y arteriales son una complicacion extraintestinal infrecuente de la enfermedad inflamatoria intestinal (EII) potencialmente prevenible. Caso clinico Varon de 62 anos, con diagnostico de enfermedad de Crohn (EC) (A3, L1 + L4, B3) que durante su ingreso para drenaje percutaneo de absceso retroperitoneal presenta episodio de tromboembolia arterial periferica de miembro superior derecho, que requirio embolectomia urgente. Tras anticoagulacion con heparina de bajo peso molecular (HBPM), se realiza estudio etiologico con hallazgo en la resonancia magnetica vascular de un trombo arterial de gran tamano en la aorta descendente, por lo que se realizo cirugia aortica y se pauto anticoagulacion indefinida con acenocumarol. Conclusion La trombosis arterial periferica es una complicacion poco comun de la EII que debe ser considerada en pacientes con enfermedad activa y prevenida adecuadamente con HBPM. El tratamiento habitual es la cirugia combinada con anticoagulacion y optimizacion de la terapia farmacologica.

Resumen La enfermedad inflamatoria intestinal (EII) es una patologia cronica y recidivante con un importante impacto sanitario, social y economico. Los pacientes con EII precisan de un seguimiento continuo y personalizado, y el uso de los recursos sanitarios en este contexto esta aumentando progresivamente. En la ultima decada, el uso de las tecnologias de la informacion y la comunicacion (TIC) han transformado el manejo de las enfermedades cronicas, como la EII. La telemedicina consiste en la aplicacion de las TIC para proporcionar atencion sanitaria a distancia sin necesidad de contacto directo con el paciente. La telemedicina y sus diferentes aplicaciones (telemonitorizacion, teleconsulta y teleeducacion) permiten un seguimiento mas estrecho, ademas de promover la autonomia del paciente y mejorar el conocimiento de su enfermedad. Estos recursos favorecen a su vez la optimizacion del tratamiento en cada momento evolutivo de la enfermedad. En esta revision se describe el impacto de las aplicaciones de la telemedicina sobre los resultados en salud de los pacientes con EII, asi como las limitaciones para la implantacion de estos sistemas en la vida real.

Despite controversy regarding the use of granulocyte/monocyte adsorption (GMA) in inflammatory bowel disease, some studies have shown favorable outcomes when it is used in steroid-dependent patients with ulcerative colitis (UC). The mechanisms responsible for such outcomes are not well characterized, but changes in immune cell populations and cytokine levels have been suggested to play an important role. We report the cases of 3 patients with chronically active severe UC who underwent GMA due to an inadequate response to standard and rescue therapy, as well as changes to their plasma cytokine profile. All the patients presented severe UC that was only partially responsive to various immunosuppressive drugs, and they were, therefore, referred for colectomy; however, all 3 refused this option, which led to the compassionate use of GMA as a last therapeutic resort. Following GMA treatment, rapid normalization of the clinical, endoscopic and laboratory parameters was observed in all the patients. Despite having achieved a good response, most cytokines remained at high concentrations after GMA, and only two, IL-6 and IL-8, showed a clear decrease throughout the GMA sessions. In view of this outcome, we hypothesize that GMA can help to lower the inflammatory load, thereby enhancing the effect of biologic drugs. To confirm this hypothesis and explore further indications for GMA, we propose the need for research directed toward the characterization of immune cell populations and their specific cytokine production rather than global cytokine assessment.

Inflammatory bowel disease (IBD), which includes ulcerative colitis (UC) and Crohn’s disease (CD), is a chronic and relapsing disorder characterized by inflammation of the gastrointestinal tract. The natural progression includes periods of flares and remission, requiring continuous and personalized follow-up to achieve long remission and minimize short and long term damage. In fact, IBD patients show significantly higher rates of utilization of healthcare resources than patients with other conditions [1]. It is important to emphasize that 30-45% of adults are nonadherents [2], making these patients five times more likely to suffer relapses and consequently increasing health care costs [3]. The high percentage of nonadherence may be due to the difficulty in accessing specialized IBD care and behavioral factors. Furthermore, IBD is associated with high levels of school and work disability [4], interference with social activities and impairment of quality of life [5]. For these reasons, IBD generates a signi...

A substantial percentage of patients fail to follow health professionals' recommendations, which affects the management of chronic diseases, reducing the effectiveness of therapeutic interventions and increasing the costs of the disease. Lack of adherence is a multidimensional phenomenon and is influenced by numerous factors that should be identified. A multiplicity of measures is available to improve adherence, such as simplifying treatment administration, but none of these measures is effective when used alone. One way of tackling lack of adherence is by identifying patients' barriers to medication and involving them in decision making. Ulcerative colitis (UC) poses a risk for lack of treatment adherence. In this disease, poor adherence correlates with poor disease control (drug effectiveness) and with higher costs. As in other chronic diseases, the causes associated with poor adherence are multiple, including psychosocial factors, the physician-patient relationship and patients' prejudices toward medication. A single dose of aminosalycylates (5-ASA) should be recommended, as this dose is as safe and effective as other regimens. However, by itself, this recommendation does not seem to improve adherence. Identifying the scale of the problem and developing strategies to involve the patient in decision making is crucial to improve treatment adherence.

Background Few data are available on the efficacy of methotrexate (MTX) in ulcerative colitis (UC). Aim To evaluate the efficacy and safety of MTX in UC patients. Patients and methods UC patients who had been treated with MTX were identified from the databases of 8 Spanish IBD referral hospitals. Patients were included in the study if they received MTX for steroid dependency or steroid refractoriness. Therapeutic success was defined as the absence of UC-related symptoms, complete steroid withdrawal and no requirement of rescue therapies within the first 6months after starting MTX. Results Forty patients were included, 70% treated for steroid dependency and 27% for steroid refractoriness. Thiopurines had been previously attempted in 87.5% of patients. The median dose of MTX used for induction was 25mg (IIQ 17.5–25) weekly given parenterally in 82.5% of cases. Eighty-five percent of patients were on steroids when MTX was started. Forty-five percent of patients met criteria for therapeutic success. Initial treatment failures were mainly due to inefficacy (50%) or intolerance (36%). After a median follow-up of 28months (IQR 22–47), 38% of patients with initial therapeutic success required new steroid courses, 22% started biological therapy, and only 1 patient required colectomy. The cumulative probability of maintaining steroid-free clinical remission was 60%, 48%, and 35% at 6, 12, and 24months after starting MTX, respectively. Eleven patients (27.5%) experienced adverse events, leading to MTX discontinuation in only 8 of them. Conclusions MTX appears to be effective to maintain clinical remission in UC, at least in the short-term, with an acceptable safety profile.

Background Epidemiological studies have shown a greater prevalence of irritable bowel syndrome (IBS) and inflammatory bowel disease (IBD) among first-degree relatives of patients diagnosed of these diseases. However, it is not known whether relatives of patients with IBD have a greater prevalence of IBS than the general population. Aims To analyse the prevalence of IBS among first-degree relatives by consanguinity (parents, siblings and offspring) and affinity (spouses) of patients with IBD. Materials and methods A prevalence study was conducted identifying 490 relatives of 91 patients with IBD. Of these, 404 met inclusion criteria; and 360 (response rate: 89.1%) answered the questionnaires. Subjects were invited to participate in the study through index cases (patients with IBD). The following variables were collected: age, sex, history of digestive diseases, kinship and cohabitation with the index case. The relatives completed a questionnaire to identify those who met Rome I and Rome II criteria for IBS. Results The overall prevalence of IBS among the first-degree relatives of patients with IBD was 49.4% and 10% according to Rome I and Rome II criteria respectively. IBS prevalence was higher in first-degree blood relatives than in spouses of patients (Rome I: 53.1% vs 29.1%, p=0.001; Rome II: 10.8% vs 5.4%, NS). No differences were found in IBS prevalence depending on whether relatives were living with the index case or not. Conclusion IBS prevalence in first-degree relatives of patients with IBD is elevated. It is significantly greater in blood relatives, which suggests involvement of genetic and psychological factors rather than environmental factors.

Treatment with antitumor necrosis factor-alpha (anti-TNF-α) offers a significant improvement in several immune-based diseases, including Crohn's disease (CD) and psoriasis. Different cutaneous side effects have been described for anti-TNF-α therapy such as psoriasis. Previous reports showed that inhibition of TNF-α can induce over expression of cutaneous IFN-α, which in turn caused a predisposition to psoriasis. We report a 31-year-old woman with extensive CD and perianal lesions, without response to conventional treatment. She paradoxically developed a cutaneous eruption with psoriasiform morphology and distribution during treatment with both anti-TNF-α approved in Europe for CD, infliximab and adalimumab. These lesions cleared after topical application of corticosteroids and cessation of the anti-TNF-α treatment. Due to uneffectiveness of pharmacological treatment on disease, the patient had to undergo surgery. TNF-induced psoriasis in patients with CD is rare and has been previously documented with infliximab or adalimumab. The reason for this apparently paradoxical effect of the therapy is still unclear. This is the first case of psoriasis induced first by infliximab and later by adalimumab in the same CD patient. We would like to review and to draw attention about psoriasis as a cutaneous side effect with anti-TNF-α treatments.

Background Ustekinumab is a fully human monoclonal antibody against IL-12/23. Ustekinumab induced clinical response and maintained higher rate of response than placebo in patients with Crohn's disease (CD). This study aims to assess the effectiveness and safety of ustekinumab in refractory patients with CD in real-life practice. Methods Consecutive patients with CD who were treated with subcutaneous ustekinumab between March 2010 and December 2014 were retrospectively included in a multicenter open-label study. Clinical response was defined by Harvey-Bradshaw index score and assessed after the loading doses, 6, 12 months, and last follow-up. Results One hundred sixteen patients were included, with a median follow-up of 10 months (interquartile range: 5-21). Clinical response after loading ustekinumab was achieved in 97/116 (84%) patients. The clinical benefit at 6, 12 months, and at the end of the follow-up was 76%, 64%, and 58%, respectively. Dose escalation was effective in 8 of 11 (73%) patients. Perianal disease also improved in 11 of 18 (61%) patients with active perianal fistulae. The initial response to ustekinumab and previous use of more than 2 immunosuppressant drugs were associated with a clinical response to ustekinumab maintenance therapy. In contrast, previous bowel resection predicted a long-term failure with ustekinumab. Adverse events were reported in 11 (9.5%) patients, but none required ustekinumab withdrawal. Conclusions Subcutaneous ustekinumab is effective and safe in a high proportion of patients with CD that were resistant to conventional immunosuppressant and antitumor necrosis factor drugs.

Resumen Antecedentes Hay una informacion limitada respecto al uso optimo de los inmunosupresores tiopurinicos en la enfermedad inflamatoria intestinal, sin que este completamente clarificada su posologia, eficacia y toxicidad. Objetivo Evaluar la evolucion clinica y los efectos adversos de los inmunosupresores tiopurinicos en condiciones de practica clinica (efectividad) y las posibles variables asociadas. Metodos Los datos se obtuvieron de una base de datos de pacientes con enfermedad de Crohn y colitis ulcerosa que iniciaban tratamiento inmunosupresor con azatioprina o mercaptopurina con un identico seguimiento preestablecido. Se definieron los conceptos de remision para cada indicacion, recidiva y toxicidad, y se analizaron las posibles variables clinicas, biologicas y demograficas (analisis multivariante) relacionadas. Resultados Un total de 150 cursos de tratamiento se evaluaron en 126 pacientes. En 118 cursos en los que la indicacion fue la induccion de la remision clinica, esta se alcanzo en el 62% de los pacientes y se mantuvo durante una media de 52 meses. La enfermedad perianal fue la unica variable que se asocio con una peor respuesta. En el 34% de los cursos se detectaron efectos adversos y estos fueron la principal causa de retirada del farmaco. La dosis plena de inicio (odds ratio [OR] = 4,26; intervalo de confianza [IC] del 95%, 1,12-16,32) y el cotratamiento con infliximab (OR = 5,6; IC del 95%, 1,17-27,1) se asociaron significativamente con una mayor retirada del farmaco por efectos adversos. Conclusiones Algunas variables fenotipicas y farmacologicas (posologia y cotratamientos) pueden tener una notable influencia en el perfil de efectos secundarios y, por tanto, en la efectividad de los inmunusupresores tiopurinicos en la enfermedad inflamatoria intestinal.

Background Recurrence after surgery to treat Crohn's disease is frequent and unpredictable. The efficacy of postsurgery capsule endoscopy in detecting recurrence in patients with Crohn's disease is yet to be confirmed. Objective To assess the safety, accuracy, and therapeutic impact of capsule endoscopy in these patients. Design Crohn's disease recurrence at the neoileum (Rutgeers score) was assessed in the patients by colonoscopy and capsule endoscopy. The M2A Patency Capsule (Given Imaging, Yoqneam, Israel) was administered 1 week before capsule endoscopy. Capsule endoscopy was performed within 2 weeks of colonoscopy. Investigators were blinded to the results of each technique. Patient comfort during the procedures was recorded. Patients Twenty-four patients with Crohn's disease with ileocolonic anastomosis were prospectively included. All patients were asymptomatic and did not receive any prophylactic treatment. Main Outcome Measurements Neoileum recurrence. Results A colonoscopy was performed in all patients, although the neoileum could not be reached in 3 of them. M2A Patency Capsule excretion was delayed in 2 patients; thus capsule endoscopy was given only to 22 patients. Recurrence was visualized with colonoscopy in 6 patients and with capsule endoscopy in 5. Ten additional recurrences were visualized only with capsule endoscopy. Moreover, proximal involvement was detected in 13 patients. Therapeutic management was modified in 16 patients. All patients preferred capsule endoscopy. Conclusions Capsule endoscopy is more effective in the evaluation of recurrence after surgery for Crohn's disease and is better tolerated than colonoscopy. This is of significant therapeutic relevance.

To investigate the influence of thiopurines and biological drugs on the presence of small intestinal bacterial overgrowth (SIBO) in patients with inactive Crohn's disease (CD).This was a prospective study in patients with CD in remission and without corticosteroid treatment, included consecutively from 2004 to 2010. SIBO was investigated using the hydrogen glucose breath test.One hundred and seven patients with CD in remission were included. Almost 58% of patients used maintenance immunosuppressant therapy and 19.6% used biological therapy. The prevalence of SIBO was 16.8%. No association was observed between SIBO and the use of thiopurine Immunosuppressant (12/62 patients), administration of biological drugs (2/21 patients), or with double treatment with an anti-tumor necrosis factor drugs plus thiopurine (1/13 patients). Half of the patients had symptoms that were suggestive of SIBO, though meteorism was the only symptom that was significantly associated with the presence of SIBO on univariate analysis (P0.05). Multivariate analysis revealed that the presence of meteorism and a fistulizing pattern were associated with the presence of SIBO (P0.05).Immunosuppressants and/or biological drugs do not induce SIBO in inactive CD. Fistulizing disease pattern and meteorism are associated with SIBO.

AIM: To evaluate the effectiveness of adalimumab in preventing recurrence after intestinal resection for Crohn’s disease in high-risk patients. METHODS: A multicenter, prospective, observational study was conducted from June 2009 until June 2010. We consecutively included high-risk Crohn’s disease patients who had undergone an ileal/ileocolonic resection. High-risk patients were defined as two or more criteria: smokers, penetrating pattern, one or more previous surgical resections or prior extensive resection. Subcutaneous adalimumab was administered 2 wk (± 5 d) after surgery at a dose of 40 mg eow, with an initial induction dose of 160/80 mg at weeks 0 and 2. Demographic data, previous and concomitant treatments (antibiotics, 5-aminosalicylates, corticosteroids, immunomodulators or biologic therapies), smoking status at the time of diagnosis and after the index operation and number of previous resections (type and reason for surgery) were all recorded. Biological status was assessed with C-reactive protein, erythrocyte sedimentation rate and fecal calprotectin. One year (± 3 mo) after surgery, an ileocolonoscopy and/or magnetic resonance enterography was performed. Endoscopic recurrence was defined as Rutgeerts score ≥ i2. Morphological recurrence was based on magnetic resonance (MR) score ≥ MR1. RESULTS: Twenty-nine patients (55.2% males, 48.3% smokers at diagnosis and 13.8% after the index operation), mean age 42.3 years and mean duration of the disease 13.8 years were included in the study. A mean of 1.76 (range: 1-4) resections previous to adalimumab administration and in 37.9% was considered extensive resection. 51.7% had previously received infliximab. Immunomodulators were given concomitantly to 17.2% of patients. Four of the 29 (13.7%) developed clinical recurrence, 6/29 (20.7%) endoscopic recurrence and 7/19 (36.8%) morphological recurrence after 1-year. All patients with clinical recurrence showed endoscopic and morphological recurrence. A high degree of concordance was found between clinical-endoscopic recurrence (κ = 0.76, P < 0.001) and clinical-morphological recurrence (κ = 0.63, P = 0.003). Correlation between endoscopic and radiological findings was good (comparing the 5-point Rutgeerts score with the 4-point MR score, a score of i4 was classified as MR3, i3 as MR2, and i2-i1 as MR1) (P < 0.001, rs = 0.825). During follow-up, five (17.2%) patients needed adalimumab dose intensification (40 mg/wk); Mean time to intensification after the introduction of adalimumab treatment was 8 mo (range: 5 to 11 mo). In three cases (10.3%), a biological change was needed due to a worsening of the disease after the dose intensification to 40 mg/wk. One patient suffered an adverse event. CONCLUSION: Adalimumab seems to be effective and safe in preventing postoperative recurrence in a selected group of patients who had undergone an intestinal resection for their CD.
