Background Telemedicine is not consistently superior to standard care in the management of inflammatory bowel disease (IBD). Non-inferiority is an acceptable outcome if telemedicine improves the efficacy and efficiency of care. Owing to the positive results of the TECCU app (Telemonitoring of Crohn’s Disease [CD] and Ulcerative Colitis [Au]) in a pilot trial1, we aimed to evaluate the time in remission and quality of life (QoL) of IBD patients controlled by telemonitoring (G_TECCU), compared to standard care (G_Control) after 12 weeks. 1Del Hoyo J et al. J Med Internet Res. 2018;20(11):e11602. Methods A 2-arm randomized multicenter study with a non-inferiority design was performed in 29 IBD centers in Spain. Adult IBD patients who initiated therapy with immunosuppressant or biological agents for disease activity were included. Exclusion criteria were: patients with ileorectal/ileo-pouch anal anastomosis, stoma, active perianal disease, no Internet access. Time in remission was evaluated with Harvey-Bradshaw/Walmsley indexes (according to CD]/UC, respectively), fecal calprotectin (FC) and reactive C protein (RCP). QoL was assessed with IBDQ-9, medication adherence with Morisky-Green index and patient satisfaction with a questionnaire derived from CSQ-8. Results We included 157 patients, and 126 were analyzed after 12 weeks of follow-up. The demographic and clinical variables are listed in Table 1. The time in remission was not inferior in patients who used the TECCU app (mean 4.2 weeks [SD 3.8]) compared with patients who received standard care (mean 4.2 weeks [SD 3.2]; difference 0.03 [95%CI -1.21 to 1.27]; p=0.017) (Figure 1). In patients with UC, disease activity improved significantly in both TECCU (mean SCCAI improvement -3.60 [SD 3.25]; p= 0.001) and standard care groups (-3.89 [SD 4.56]; p=0.001;). In patients with CD, clinical activity also improved significantly in both groups (mean Harvey-Bradshaw improvement -1.65 [SD 2.51]; p=0.001 in TECCU; -2.24 [SD 4.15]; p=0.001 in standard care group). Similarly, FC and CRP values improved significantly in both groups (Figure 2). Considering QoL, the IBDQ-9 score improved significantly in TECCU (mean 11.29 [SD15.8]; p Conclusion In IBD patients who initiate biological agents or immunomodulators, TECCU app is not inferior to standard care to maintain remission in the short-term. Telemonitoring with TECCU app associated a higher improvement in medication adherence and an increase in QoL. Long-term results are needed to confirm it.

Background The long-term outcome of patients after antitumour necrosis factor alpha (anti-TNF) discontinuation is not well known. Aims To assess the risk of relapse in the long-term after anti-TNF discontinuation. Methods This was an extension of the evolution after anti-TNF discontinuation in patients with inflammatory bowel disease (EVODIS) study (Crohn's disease or ulcerative colitis patients treated with anti-TNFs in whom these drugs were withdrawn after achieving clinical remission) based in the same cohort of patients whose outcome was updated. Clinical remission was defined as a Harvey-Bradshaw index ≤4 points in Crohn's disease, a partial Mayo score ≤2 in ulcerative colitis and the absence of fistula drainage despite gentle finger compression in perianal disease. Results This was an observational, retrospective, multicenter study. A total of 1055 patients were included. The median follow-up time was 34 months. The incidence rate of relapse was 12% per patient-year (95% confidence interval [CI] = 11-14). The cumulative incidence of relapse was 50% (95% CI = 47-53): 19% at one year, 31% at 2 years, 38% at 3 years, 44% at 4 years and 48% at 5 years of follow-up. Of the 60% patients retreated with the same anti-TNF after relapse, 73% regained remission. Of the 75 patients who did not respond, 48% achieved remission with other therapies. Of the 190 patients who started other therapies after relapse, 62% achieved remission with the new treatment. Conclusions A significant proportion of patients who discontinued the anti-TNF remained in remission. In case of relapse, retreatment with the same anti-TNF was usually effective. Approximately half of the patients who did not respond after retreatment achieved remission with other therapies.

Background Main aim: To evaluate the retention rate of ustekinumab compared to vedolizumab in Crohn’s disease patients who failed anti-TNF therapy in clinical practice. Secondary aims: To compare the short-term and long-term effectiveness, and the safety of both treatments. Methods Crohn’s disease patients who had received either vedolizumab or ustekinumab after failure or intolerance to anti-TNF agents from ENEIDA registry were included. ENEIDA is a prospectively maintained database promoted by GETECCU. A total of 755 patients from 30 centres were included at time of data extraction. Clinical activity was classified based on Harvey-Bradshaw index both at short (during induction) and in the long-term. Kaplan-Meier curves, Cox regression models, inverse probability weighting and propensity matching score analyses were performed to compare both drugs and to identify predictive factors of treatment effectiveness and durability. Results 755 patients were included (195 in the vedolizumab cohort and 560 in the ustekinumab cohort). After a median of 20 months (IQR 7.4–30) of follow-up, the survival rate for ustekinumab therapy was higher than vedolizumab (Figure 1). The propensity matching score verified the differences between both therapies. The short-term proportion of patients on clinical remission, steroid-free remission and clinical response was also superior in the ustekinumab cohort (Figure 2). In the long-term, significant differences were observed 2 years after the beginning of the treatments, although no differences in clinical response and remission rates were detected in patients who achieved clinical response at week 16 between both cohorts. Vedolizumab was discontinued in 142 patients and ustekinumab in 185, mainly due to primary non-response (52% in the vedolizumab and 58% in the ustekinumab cohort) and loss of response (34% and 25%, respectively) despite the fact that 35% of the patients required intensification. The predictive factors associated to the discontinuation of the therapy are described in table 1. Adverse events were observed, overall, in 12% of the patients, without differences between both groups (Table 2). Following the discontinuation of the treatment with vedolizumab/ustekinumab, other biologic agents were prescribed in 56% of the patients, and 27% underwent surgery. Conclusion In clinical practice, a relatively high proportion of Crohn’s disease patients who received ustekinumab or vedolizumab for anti-TNF failure, maintained these drugs in the medium-long term, although ustekinumab retention rate was higher in comparison with vedolizumab.

Background Some patients with Inflammatory Bowel Disease (IBD) who are treated with anti-TNFα therapy develop a drug-induced psoriasis (IP) as an adverse event. There are some therapeutic approaches, being more frequent to change the biologic therapy to ustekinumab, effective and approved for the treatment of both entities. This could be the best option, but available data are lacking and it could increase the risk of IBD relapse. Our aim is to assess the management of anti-TNF IP in IBD, and the subsequent evolution of both diseases in a large nationwide cohort of patients. Methods Retrospective, observational multicenter study from the prospectively maintained Spanish ENEIDA registry. Participants were patients with IBD and anti-TNFα IP. At baseline, psoriasis severity was classified as mild, moderate or severe, and remission was defined as the resolution of skin lesions, clinical response as an improvement without complete resolution, and no response as the absence of improvement. IBD clinical activity was defined based on Harvey-Bradshaw Index and Partial Mayo Score. All items were evaluated when available at baseline and 16, 32 and 54 weeks. Results Anti-TNFα IP was reported in 234 patients (CD: 185, UC: 46, unclassified IBD: 3). SWAP strategy was chosen in 76 patients (32.5%), most of them to ustekinumab (90.8%), 71 (30.3%) patients continued anti-TNF, 49 (20.9%) discontinued it, and in 38 (16.2%) a switch to a second anti-TNF was made. The decision to continue or not anti-TNF was associated to psoriasis severity (p Conclusion Evaluating IBD activity and psoriasis severity is essential before modifying IBD treatment due to IP. Continuing anti-TNF treatment in mild psoriasis cases, and considering SWAP to ustekinumab in moderate-severe ones, could be a suitable strategy.

Background The use of ustekinumab (UST) and vedolizumab (VDZ) as first line therapy for inflammatory bowel disease (IBD) is increasing due to safety reasons and contraindications of anti-TNFs. However, there are no studies evaluating their efficacy and safety in clinical practice under these circumstances. Thus, our aims were to describe bionaïve patients’ characteristics starting VDZ or UST and to evaluate treatment persistence of these drugs and their safety profile in this scenario. Methods Descriptive, retrospective and multicenter study based on the ENEIDA registry (a large, prospectively maintained database of the Spanish Working Group in IBD –GETECCU). All IBD patients never exposed to biological agents who started VDZ or UST as first-line biological treatment were identified. Results Out of 29,450 IBD patients ever exposed to biological drugs included in the ENEIDA registry, 924 patients met the inclusion criteria. Of these, 366 (40%) started UST and 558 (60%) VDZ as first line biological therapy. UST group: 48% women, 90% Crohn's disease (43% ileal; 13% colic; 43.5% ileocolic; 31% upper gastrointestinal involvement; 25% stricturing behaviour; 12% penetrating, 18% perianal disease), 10% ulcerative colitis (74% extensive, 17% left-sided, 9% proctitis), 27% had extraintestinal manifestations (EIM). Median age at the beginning of UST was 57 years (IQR 57-70), 17% patients had a past history of malignancy and, 34% had associated comorbidities. UST indication was luminal activity except in 2% for perianal disease and 5% for EIM. At the end of follow-up (median 14 months [IQR 6-30]), 12 patients (3.3%) developed adverse effects (AEs) that led to treatment discontinuation in the majority of them (92%). VDZ group: 44% women, 42% Crohn's disease (44% ileal; 18% colic; 38% ileocolic; 25% upper gastrointestinal involvement; 28% stricturing behaviour; 13% penetrating; 7% perianal disease), 58% ulcerative colitis (50% extensive, 42% left-sided, 8% proctitis), 17% had EIM. The median age at the beginning was 61 years (IQR 48-71), 24% had past history of malignancy and, 34% associated comorbidities. The indication was exclusively luminal activity. At the end of follow-up (median 21 months [IQR 8-36]), 36 patients (6.5%) had AEs, that lead to treatment withdrawal in 67% of them (24 patients). Cumulative treatment persistence rates were 78%, 60% and 50% for VDZ and 85%, 75% and 66% for UST at 12, 24 and 36 months, respectively (P Conclusion In clinical practice, VDZ and UST are used first-line particularly in elderly patients with comorbidities. Both treatments have a good safety profile and a high persistence of treatment, being superior for ustekinumab.

OBJECTIVES: The aim of this study was to examine the incidence of coronavirus disease 2019 (COVID-19) among patients with immunomediated inflammatory diseases (IMIDs) treated with biologic or targeted synthetic disease-modifying antirheumatic drugs (bDMARDs and tsDMARDs) and to evaluate the influence of either IMIDs or related therapies on the incidence and evolution of COVID-19. METHODS: This observational, cross-sectional study was conducted from January 31, 2020, to May 15, 2020. Data of 902 patients were obtained from clinical records in hospitals, primary care units, and community pharmacies. Inclusion criteria were adults with IMIDs treated with bDMARDs or tsDMARDs who started therapy 3 months prior to study commencement. Patients with poor adherence to treatments were excluded. COVID-19 was classified as "definitive" (severe acute respiratory syndrome coronavirus 2 polymerase chain reaction [PCR]-positive), "possible" (characteristic symptoms and negative PCR), and "suspected" (characteristic symptoms but PCR not performed). RESULTS: COVID-19 was diagnosed in 70 patients (11 definitive, 19 possible, and 40 suspected). The cumulative incidence of definitive COVID-19 was 1.2%. When considering all cases, the incidence was 7.8%. Patients on biosimilars tumor necrosis factor blockers were more likely to have a diagnosis of COVID-19 (odds ratio, 2.308; p < 0.001). Patients on anti-B-cell therapies had a lower incidence of infections (p = 0.046). Low rates of hospitalization (14.3%), pneumonia (14.3%), death (2.9%), or thrombosis (2.9%) were observed, and 94.3% of patients recovered. CONCLUSIONS: The cumulative incidence of confirmed cases of COVID-19 was similar to the general population, with generally low hospitalization, intensive care management, and mortality rates. COVID-19 incidence was less frequent in patients with more severe immunosuppression.

Background Pouchitis and other inflammatory pouch diseases (IPD) are frequent in pouch-carrying patients operated for a previous diagnosis of ulcerative colitis. We evaluated characteristics and differences in therapeutic requirements between pouchitis, Crohn′s-like disease of the pouch (CDP) and cuffitis. Methods This is a retrospective and multicentric Spanish cohort of GETECCU (RESERVO Study), including pouch-carrying patients (operated 1995 to 2016) with previous ulcerative colitis, ileostomy closure and subsequent diagnosis of IPD (pouchitis, CDP or cuffitis), following ECCO diagnostic criteria1. Follow up extended to June 2020. Pouchitis was categorized attending current classifications. Use of medical and surgical therapies was collected and differences between pouchitis and CDP were analyzed using descriptive and comparative statistics. Results A total of 338 patients were included. Demographic and clinical characteristics are presented in Table 1. The most frequent IPD was pouchitis (n=258, 76%), followed by CDP (n=55, 16%) and cuffitis (n=25, 7.4%). Pouchitis was diagnosed at a median time of 27 (range 1–342) months. Prevalence according to pouchitis classification is presented in Figure 1. CDP was diagnosed at a median time of 77 (range 5–324) months, around 75% with a previous pouchitis diagnosis. Location of CDP (not mutually excludent) was pouch CDP (91%), 87% pre-pouch ileitis, and 41% perianal disease. Regarding behavior: 26 (47%) were inflammatory, 12 (22%) stricturing and 17 (31%) penetrating (8 rectovaginal fistulas). Cuffitis was diagnosed at a median time of 18 (range 1–219) months. Medical and surgical therapies used are shown in Figure 2. Immunosuppressants (58.2 vs 22.4%, p 0.001), biologics (74.5 vs 34.8%, p 0.0001), and surgery (41.8 vs 21.3%, p 0.003) were more used in CDP than in pouchitis. Conclusion Pouchitis and CDP are heterogeneous inflammatory pouch complications with a wide and high therapeutic requirement. CDP presents a later diagnosis and has higher therapeutic needs than pouchitis. 1.

Background Crohn’s disease (CD) can develop fistulizing complications at any time during the disease course. Enterocutaneous fistulas (ECF) are disabling lesions with a significant impact on quality of life. The aim of this study was to describe the characteristics and natural history of ECF complicating CD, and to analyze its medical and/or surgical management. Methods A retrospective analysis of all adult patients with fistulizing CD with at least one episode of ECF from the ENEIDA registry (over 68,000 patients) was performed. ECF were defined as a communication between the gastrointestinal tract and the skin producing leakage of luminal contents. Additional data describing the ECF and its medical or surgical management were gathered. The main endpoint was any ECF-related surgical intervention. Fistula closure was defined as the absence of drainage, with no new abscess or surgery for at least 6 months. A comparison of the characteristics and outcomes after the availability of biologic agents (Jan/2000) was also performed. The baseline characteristics were analyzed by means of descriptive statistics and were compared by non-parametric tests. Factors associated with surgery were further evaluated in a binary multivariable regression and survival analysis. Results A total of 301 ECF in 286 patients from 46 hospitals diagnosed between Jan/1970-Sept/2020 were included (median age 34 years (IQR, 27–46); 59% male; 67% L3). ECF had a median of 1 external opening (range 1–10), 59% with concomitant internal fistulas, and usually involved the ileum (67%) or colon (23%). After 146 months (IQR, 69–233) of follow-up, 37% received thiopurines, 40% anti-TNF, 6% ustekinumab and 2% vedolizumab. Surgery was performed in 208 patients (69%) after a median of 4 months (IQR, 1.4–12). Fistula closure was achieved in 253 patients (84%) after 30 months (IQR, 4–84), mostly after surgery (54%) and in one third after medical therapy. Fistula recurrence was uncommon (11%) after closure. Patient and fistula characteristics were significantly different after the availability of biologics. In fact, anti-TNF biologics and thiopurines reduced surgery risk (HR 0.5; 0.38–0.67; HR 0.64; 0.47–0.86, respectively). The surgery rate in the biologic era tends to be lower than before (OR 0.63;0.33–1.09) while timing is similar. Closure rates are also comparable, but it was obtained more frequently after medical therapy once biologicals were available (OR 2.21; 1.13–4.29). Conclusion ECF complicating CD entail a high burden of medical and surgical resources. Closure rates are high, usually after surgery, and fistula recurrence is uncommon. A number of patients can benefit from medical therapy and achieve fistula closure.

Background The effectiveness of the switch to another anti–tumor necrosis factor (anti-TNF) agent is not known. The aim of this study was to analyze the effectiveness and safety of treatment with a second and third anti-TNF drug after intolerance to or failure of a previous anti-TNF agent in inflammatory bowel disease (IBD) patients. Methods We included patients diagnosed with IBD from the ENEIDA registry who received another anti-TNF after intolerance to or failure of a prior anti-TNF agent. Results A total of 1122 patients were included. In the short term, remission was achieved in 55% of the patients with the second anti-TNF. The incidence of loss of response was 19% per patient-year with the second anti-TNF. Combination therapy (hazard ratio [HR], 2.4; 95% confidence interval [CI], 1.8–3; P < 0.0001) and ulcerative colitis vs Crohn’s disease (HR, 1.6; 95% CI, 1.1–2.1; P = 0.005) were associated with a higher probability of loss of response. Fifteen percent of the patients had adverse events, and 10% had to discontinue the second anti-TNF. Of the 71 patients who received a third anti-TNF, 55% achieved remission. The incidence of loss of response was 22% per patient-year with a third anti-TNF. Adverse events occurred in 7 patients (11%), but only 1 stopped the drug. Conclusions Approximately half of the patients who received a second anti-TNF achieved remission; nevertheless, a significant proportion of them subsequently lost response. Combination therapy and type of IBD were associated with loss of response. Remission was achieved in almost 50% of patients who received a third anti-TNF; nevertheless, a significant proportion of them subsequently lost response.

Background INFEII registry (ClinicalTrials.gov: NCT02904590) is a prospective study promoted by GETECCU to determine the incidence and risk factors of infection in an inception cohort of IBD patients. Despite preventive measures and recommendations of scientific societies, TB remains a problem in patients with IBD treated with immunosuppressants (IMM) and biologics. AIMS To asses: (1) the screening of TB performed at the time of inclusion of a patient in the INFEII registry, (2) the incidence of latent TB; and (3) compliance with national and European recommendations. Methods A longitudinal prospective study of incident cases with IBD, initiated in October 2016 and with a planned follow-up of 5 years. In September 2019, INFEII registry had 1241 patients from 28 centres throughout Spain. The study protocol determines the mandatory fulfilment of TB screening in every patient, leaving to the centre the freedom of decision on what procedures to perform. Guidelines recommend a mandatory study before starting immunosuppression, especially with biological treatment, using the combination of tuberculin skin test (TST) and interferon-gamma release assay (IGRA) or at least one TST with a booster test1,2. Results Of the 1241 patients 233 (19%) had no screening, 494 (40%) had one [TST 158, IGRA 299, thorax-X-ray 37], 288 (23%) two [TST + IGRA 87, IGRA + thorax-X-ray 130, TST + thorax-X-ray 30, TST + booster 41], 128 (10%) three [TST + IGRA + thorax-X-ray 65, TST + booster + IGRA 23, TST + booster + thorax-X-ray 40] and 98 (7.9%) the four tests [TST + booster + IGRA + thorax-X-ray]. 486 patients (48%) receive pharmacological immunosuppression (172 IMMS, 195 biologics, 119 COMBO) and from them 198 (41%) followed the guidelines recommendation (131 TST and IGRA and 118 TST-booster), 245 (50%) had some method for TB screening [TST 43, IGRA 112, thorax-X-ray 15, IGRA + thorax-X-ray 57, TST + thorax-X-ray 18] and 43 patients (8.8%) had no screening. With the baseline screening, latent TB was detected in 134 patients (13%), 63 (47%) receiving anti-TB chemotherapy. In patients initiating immunosuppression, latent TB was detected in 35 cases [of which 28 received prophylaxis but 7 under IMM did not]. Active TB was detected in 4 cases: 2 during baseline screening, one without screening and one with negative screening (negative TST and IGRA, without booster receiving biological treatment). Conclusion Despite TB in IBD is a relevant problem, there is ample room for improvement for the implementation of mandatory minimum screening recommendations, even in prospective protocolised projects.

Background Three anti-TNFs (one intravenous and two subcutaneous) are licensed for the treatment of ulcerative colitis (UC). However, it is not known if the efficacy of a second anti-TNF changes on whether it is intravenous or subcutaneous; this could justify the indication of biological agents with a different mechanism of action in second line. The aim of this study was to compare the efficacy of a second subcutaneous or intravenous anti-TNF in UC. Methods Patients from the prospectively maintained ENEIDA registry treated with consecutively intravenous and subcutaneous anti-TNF, who were naïve to biological agents, were identified. Patients were classified according to the administration route of the first anti-TNF in: IVi (intravenous initially) or SCi (subcutaneous initially). Patients treated for extraintestinal manifestations or pouchitis were excluded. Clinical activity and effectiveness were defined based on Partial Mayo Score (PMS) at baseline, 14 and 52 weeks. Loss of response, dose-escalation and treatment discontinuation were also assessed. Results 372 UC patients were included (270 IVi and 102 SCi). Both cohorts were similar in clinical-epidemiological characteristics, except for a higher proportion of patients with moderate-to-severe clinical activity at the beginning of the first anti-TNF in the IVi group (82% vs. 71%; p = 0.017) and at the beginning of the second anti-TNF (62% vs. 74%; p = 0.04). Clinical response and remission rates at week 14 for the second anti-TNF were 41% and 29% in IVi vs. 47% and 25% in SCi, respectively (p = ns). At week 52, clinical response/remission rates of the second anti-TNF were 37%/32% in IVi vs. 40%/29% in SCi (p = ns). A higher response rate at 14 weeks with the second anti-TNF was detected in the SCi group (40% vs. 68%; p = 0.012) when the reason for withdrawal of the first anti-TNF was secondary loss of response. The cumulative persistence of the second anti-TNF treatment in IVi and SCi were 55% and 54% after 1 year, and 41% and 40% after 2 years, respectively (p = ns). The SCi group had lower rates of dose-escalation with the second anti-TNF than IVi (34% and 29% in SCi vs. 57% and 49% in EVi, at 12 and 24 months, respectively -p = 0.004-). Dose-escalation of the first anti-TNF and moderate-to-severe clinical activity at the beginning of the second anti-TNF were associated with a lower probability of remission with the second anti-TNF in the short- and long-term. Conclusion The efficacy of infliximab after failure/intolerance of a subcutaneous anti-TNF is similar to that of subcutaneous anti-TNFs after infliximab failure/intolerance.

The impact of prior anti-TNF use on “real-life” outcomes of adalimumab therapy in ulcerative colitis (UC) is not well known. To compare the influence of prior anti-TNF use on the outcomes of adalimumab maintenance treatment in UC patients. We also assessed the effectiveness of adalimumab dose escalation. This retrospective multicenter cohort study included consecutive UC who advanced to an adalimumab maintenance regimen. Patients in whom adalimumab was discontinued prior to week eight of treatment were excluded. The co-primary efficacy endpoints were the cumulative probabilities of adalimumab failure-free survival and colectomy-free survival. We also assessed the need for and the effectiveness of adalimumab dose escalation. Of 184 UC on maintenance treatment with adalimumab, 116 (63%) had previous anti-TNF use. After a median follow-up of 23 months (interquartile range 13–49), 112 patients (60%) maintained corticosteroid-free clinical response. Sixty-nine patients (37%) had adalimumab failure, and 22 (12%) needed colectomy. Anti-TNF-naive patients had significantly lower adjusted rates of adalimumab failure (hazard ratio [HR] 0.65; p

To describe clinical practice with infliximab (IFX) in ulcerative colitis (UC); identification of predictive factors for IFX treatment discontinuation due to insufficient response and for colectomy.Retrospective, multicentric and observational study including every UC IFX-treated patient in 10 Spanish hospitals. Variables analyzed: epidemiological data; variables for poor prognosis; IFX prior treatments; characteristics of the IFX treatment; time from the UC diagnosis to induction with IFX; time from induction to colectomy or until data collection. Predictive and protective factors for IFX discontinuation due to lack of response and for colectomy were analyzed with binary logistic regression and Cox analysis.Follow-up time from induction with IFX to the collection of data or colectomy: 36.7 ± 25.7 months. Prior treatment with immunomodulator medications (IMM): 79%; IFX + immunosuppressant therapy: 77%; discontinuation of IFX: 26%, colectomy 16%. Independent predictive or protective factors for IFX discontinuation: IMM resistance (OR: 2.9, p = 0.022, 95% CI: 1.2-7.2), prior use of leukocytapheresis (OR: 3.3, p = 0.024, 95% CI: 1.1-9.4), IFX + IMM therapy (OR: 0.3, p = 0.022, 95% CI: 0.1-0.9, and HR: 0.4, p = 0.006, 95% CI: 0.2-0.8) and corticosteroid use in induction (HR: 1.9, p = 0.049, 95% CI: 1.0-3.8). Independent predictive or protective factors for colectomy: Use of leukocytapheresis (OR: 3.0, p = 0.036, 95% CI: 1.1-8.4), IFX + IMM therapy (OR: 0.3, p = 0.022, 95% CI: 0.1-0.8, and HR: 0.3, p = 0.011, 95% CI: 0.1-0.8) and severe cortico-resistant flare-up (HR: 2.5, p = 0.032, 95% CI: 1.1-5.9).Prior use of IMM and leukocytapheresis, the use of corticosteroids in induction and a severe cortico-resistant flare predict a worse response to IFX and the need for colectomy. Combination therapy is a protective factor for both.

To evaluate the use of health care resources and the associated costs of complex perianal Crohn's disease (CD) from the National Health System perspective.We conducted a multicenter, retrospective, observational study in which gastroenterologists from 11 hospitals in the Community of Madrid took part. Data was collected on the direct healthcare resources (pharmacological treatments, surgical procedures, laboratory/diagnostic tests, visits to specialists and emergency departments, and hospitalizations) consumed by 97 adult patients with complex perianal CD which was active at some point between January 1, 2005, and case history review.We recorded 527 treatments: 73.1% pharmacological (32.3% antibiotic, 20.5% immunomodulator, 20.3% biological) and 26.9% surgical. Mean annual global cost was €8,289/patient, 75.3% (€6,242) of which was accounted for by pharmacological treatments (€13.44 antibiotics; €1,136 immunomodulators; €5,093 biological agents), 12.4% (€1,027) by hospitalizations and surgery, 7.7% (€640) by medical visits, 4.2% (€350) by laboratory/diagnostic tests, and 0.4% (€30) by emergency department visits.Pharmacological therapies, and in particular biological agents, are the main cost driver in complex perianal CD; costs due to surgery and hospitalizations are much lower.

Methotrexate is an effective treatment for inflammatory bowel disease (IBD). However, long-term treatments have been associated with the development of liver fibrosis. FibroScan® is a noninvasive, safe, and effective technique to evaluate liver fibrosis.To evaluate the presence of significant liver fibrosis by transient elastography (FibroScan®) in IBD patients treated with methotrexate.Cross-sectional study including IBD patients treated with methotrexate from different hospitals. Clinical and analytical data, duration of treatment, and cumulative dose of methotrexate were obtained. Liver stiffness was assessed by FibroScan®. The cutoff value for significant liver fibrosis (according to METAVIR) was F ≥ 2: 7.1 kPa. Results. In the study, 46 patients were included, 30 women (65%), with a mean age of 43 ± 10 years. 31 patients had Crohn's disease (67.4%), 13 ulcerative colitis (28.3%), and 2 indeterminate colitis (4.3%). The mean cumulative dose of methotrexate was 1242 ± 1349 mg, with a mean treatment duration of 21 ± 24 months. The mean value of liver stiffness was 4.7 ± 6.9 kPa. There were 35 patients (76.1%) with F01, 8 patients (17.4%) with F = 2, and 3 patients with F ≥ 3 (6.5%). There were no differences in liver stiffness depending on sex, age, type of IBD, or cumulative dose of methotrexate.(1) Development of advanced liver fibrosis in IBD patients treated with methotrexate is exceptional. (2) There were no differences in liver stiffness depending on the type of IBD or the cumulative dose of methotrexate. (3) FibroScan® may be potentially useful for evaluation and follow-up of liver fibrosis in methotrexate-treated patients.

To evaluate effectiveness and safety of adalimumab in CD patients of the Madrid area and identify predictors of response.Multicenter retrospective survey of all CD patients treated with adalimumab in 9 hospitals of the Madrid area (Spain). Univariate and multivariate analysis of predictors of response was performed.174 patients included (50% males) with a median follow-up of 40 weeks. 30% had active perianal fistulizing disease at the beginning of the therapy with adalimumab. 59% had been previously treated with infliximab, being the lost of response (42.2%) the most frequent cause of withdrawal of the drug. 33% of patients needed dose escalation from every-other week to every week. The median time for this dose escalation was 33 weeks (range 2-120). The percentages of complete response at 4 weeks, 6 months and end of follow-up were 63, 70 and 63% in luminal disease and 49, 50 and 41% in perianal disease respectively. The prevalence of adverse events was 18% (most frequent was: 5 abscesses) causing the withdrawal of the drug in 21% of them.Adalimumab is effective and safe for the management of CD, even in refractory cases to infliximab.

Aliment Pharmacol Ther 2011; 34: 544–554 Summary Background Low thiopurine-methyl-transferase (TPMT) activity and high 6-thioguanine-nucleotide (6TGN) concentrations have been linked to therapeutic success in inflammatory bowel disease patients treated with thiopurines; however, this has not been implemented in clinical practice. Aim To identify a therapeutic threshold value for TPMT or 6TGN concentrations, and their capability to predict treatment safety and efficacy. Methods Prospective multicentre study including steroid-resistant/dependent patients starting thiopurines. The TPMT activity was determined at inclusion (>5 U/mL required). Azathioprine metabolites [6TGN, 6-methyl-mercaptopurine ribonucleotides (6MMP), and 6TGN/6MMP and 6TGN/TPMT ratios] were periodically monitored during steroid tapering and after withdrawal for 6 months or until a new flare occurred. Results A total of 113 patients were analysed (62% clinical response). Areas under the receiver operating characteristic (ROC) curve (AUC) relating clinical response and metabolite levels at 2, 4 and 6 months after steroid withdrawal were less than 0.7. The AUCs relating final response and initial TPMT activity or metabolite concentrations at 2, 4, 8 and 16 weeks after starting thiopurines were less than 0.7. No cut-off point with worthwhile sensitivity/specificity was found. Eight (7%) patients developed thiopurine-related toxicity that could not be linked to TPMT activity or 6TGN levels. Conclusions Our results do not support determination of TPMT activity or 6TGN concentrations to predict treatment outcome, and no useful serum metabolites threshold value to adjust the drug’s dose was identified.

Background: The aim was to evaluate the efficacy and tolerance of oral and intravenous iron treatment in anemic inflammatory bowel disease (IBD) patients, considering both hematological and quality-of-life outcomes. Methods: We performed a prospective multicenter study in IBD patients with iron deficiency anemia. Patients having hemoglobin >10 g/dL were prescribed oral ferrous sulfate. If hemoglobin

Even before the discovery of Helicobacter pylori as their cause, chronic gastritis and peptic ulcer disease were empirically treated with anti-infectious agents. However, it was not until that finding that an antibiotic approach began to be used systematically. The main aim of this article is to review the evolution of H. pylori therapy from a meta-analytical perspective. Initially, antibiotic monotherapy had a minor efficacy on H. pylori. Dual therapy including either bismuth compounds or proton-pump inhibitors (PPI) and one antibiotic also resulted in insufficient cure rates. Bismuth-based triple therapy (the first used) and PPI-based triple therapies (combined with two antibiotics, including amoxicillin, nitroimidazole, or clarithromycin) have been the most widely recommended. PPI-based regimens are superior to H2-antagonist-based ones. The influence of the type of PPI, the dose and the duration of the treatment will be discussed. Among the factors influencing the efficacy of therapy, resistance to clarithromycin and metronidazole are the most important risk factors for eradication failure. Several rescue therapies can be used. Bismuth-based quadruple therapy is effective, but the complexity of the regimen and the associated adverse effects limit the compliance. PPI-based triple therapy with amoxicillin and levofloxacin is at least equally effective and better tolerated.

To describe the manometric findings detected in adult patients with dysphagia that were diagnosed of eosinophilic oesophagitis, and to compare with the cases of eosinophilic infiltration of the oesophagus reported in the literature.We present 12 adult patients diagnosed as suffering from this disorder in our department in a 1.5-year period, according to histological criteria and discarding any other cause of eosinophilic infiltration of the oesophagus. Stationary oesophageal manometry using a hydropneumocapillary perfusion system was performed in every case. The recommendations of the Spanish Group of Digestive Motility were followed for the interpretation of the results. In seven patients who presented motor disorder in manometric evaluation, treatment with steroid oesophageal lavage using fluticasone propionate was carried out and these patients were subsequently re-evaluated.All patients were young predominantly men, and the first endoscopic examination showed regular concentric stenosis or a 'ring oesophagus'. Six patients had a severe nonspecific oesophageal motor disorder characterized by up to 80% of nontransmitted or very low-amplitude waves in the lower two-thirds of the organ. Three patients presented a manometric disturbance characterized by hyperkinetic peristaltic waves in distal oesophageal third. One patient had an alteration of the oesophageal motor dynamics characterized by 80% of deglutory complexes formed by a primary simultaneous wave in the two lower oesophageal thirds followed by a secondary peristaltic wave in 50% of cases that had a normal duration and amplitude. The remaining two patients had normal oesophageal motility. The upper oesophageal sphincter showed no alterations, and the manometric evaluation of the lower oesophageal sphincter tone proved normal in 10 patients, with slight hypotension in two cases. In seven of the nine patients who presented an oesophageal motor disorder, treatment with steroid oesophageal lavage using fluticasone propionate was administered and a new oesophageal manometry was performed afterwards, in which the motor disorder was clearly improved as soon as dysphagia, endoscopic lesions and histopathologic alteration disappeared.In the literature, 61 cases of eosinophilic infiltration of the oesophageal mucosa subjected to oesophageal manometric study had been described, and 60.6% of them showed evidence of different types of manometric alterations, mainly with spastic or hypercontractility characteristics. Although six of our cases showed very deficient peristalsis with very low-amplitude or nontransmitted waves, and in another three high-amplitude peristaltic waves were recorded. Motor disorders improved parallel to the disappearance of the eosinophilic infiltration of the mucosa. These data suggest that motor disorders in eosinophilic oesophagitis are a consequence of eosinophil infiltration of the oesophagus and should be considered in the differential diagnosis of dysphagia. These manometric alterations could be considered as primary nonspecific disorders and included in the 'ineffective oesophageal motility' group.

The outcomes of infliximab dose escalation in ulcerative colitis (UC) have not been well evaluated. To assess the short- and long-term outcomes of infliximab dose escalation in a cohort of patients with UC. This was a multicenter, retrospective, cohort study. All consecutive UC patients who had lost response to infliximab maintenance infusions and who underwent infliximab dose escalation were included. Post-escalation short-term clinical response and remission were evaluated. In the long term, the cumulative probabilities of infliximab failure-free survival and colectomy-free survival were calculated. Predictors of short-term response and event-free survival were estimated using logistic regression analysis and Cox proportional hazard regression analysis. Seventy-nine patients were included. Fifty-four patients (68.4 %) achieved short-term clinical response and 41 patients (51.9 %) entered in clinical remission. After a median follow-up of 15 months [interquartile range (IQR) 8–26], 33 patients (41.8 %) had infliximab failure. Patients with short-term response had a significantly lower adjusted rate of infliximab failure [hazard ratio (HR) 0.24, 95 % confidence interval (CI) 0.12–0.49; p

espanolIntroduccion: la intensificacion del tratamiento con infliximab (IFX) en la colitis ulcerosa (CU) es mas frecuente de lo establecido en estudios pivotales. Objetivos: establecer la frecuencia y forma con la que intensificamos en CU en practica clinica, los factores predictores y comparar la evolucion entre los pacientes con tratamiento intensificado y no intensificado. Metodos: estudio retrospectivo de 10 hospitales y 144 pacientes con respuesta a la induccion con IFX. Se analizaron variables predictoras de la intensificacion con analisis de regresion de Cox. Se comparo la evolucion, perdida de respuesta a IFX y colectomia segun tratamiento intensificado o no intensificado. Resultados: tiempo de seguimiento desde la induccion hasta la recogida de datos: 38 meses [rango intercuartil (RIC) 20-62]. Tiempo de tratamiento con IFX: 24 meses (RIC, 10-44). El 37% de los pacientes requirio intensificacion. Se acorto el intervalo en 36 pacientes, se aumento la dosis en 7, ambas en 10. La introduccion simultanea de inmunosupresores tiopurinicos (INM) e IFX predijo la intensificacion de forma independiente [Hazard ratio (HR) 0,034 p 0,006 IC 0,003-0,371]. En los pacientes con tratamiento intensificado fue mas frecuente la suspension de IFX por perdida de respuesta (30,4% vs. 10,2% p 0,002), la reintroduccion de corticoides (35% vs. 18%, p 0,018) y la colectomia (22% vs. 6,4% p 0,011). El 17% de los pacientes intensificados volvio a recibir 5 mg/kg cada 8 semanas. Conclusiones: la intensificacion es frecuente y en ocasiones reversible. La introduccion del INM en el momento de la induccion con IFX predice la no intensificacion. La intensificacion, aunque eficaz, se asocia a una peor evolucion. EnglishIntroduction: Infliximab (IFX) therapy intensification in ulcerative colitis (UC) is more common than established in pivotal studies. Objectives: To establish the frequency and form of intensification for UC in clinical practice, as well as predictors, and to compare outcomes between intensified and non-intensified treatment. Methods: A retrospective study of 10 hospitals and 144 patients with response to infliximab (IFX) induction. Predictive variables for intensification were analyzed using a Cox regression analysis. Outcome, loss of response to IFX, and colectomy were compared between intensified and non-intensified therapy. Results: Follow-up time from induction to data collection: 38 months [interquartile range (IQR), 20-62]. Time on IFX therapy: 24 months (IQR, 10-44). In all, 37% of patients required intensification. Interval was shortened for 36 patients, dose was increased for 7, and 10 subjects received both. Concurrent thiopurine immunosuppressants (IMM) and IFX initiation was an independent predictor of intensification [Hazard ratio, 0.034; p, 0.006; CI, 0.003-0.371]. In patients on intensified therapy IFX discontinuation for loss of response (30.4% vs. 10.2%; p, 0.002), steroid reintroduction (35% vs. 18%; p, 0.018), and colectomy (22% vs. 6.4%; p, 0.011) were more common. Of patients on intensification, 17% returned to receiving 5 mg/kg every 8 weeks. Conclusions: Intensification is common and occasionally reversible. IMM initiation at the time of induction with IFX predicts non-intensification. Intensification, while effective, is associated with poorer outcome.

Resumen La purpura trombocitopenica idiopatica es una manifestacion extraintestinal poco frecuente de la enfermedad inflamatoria intestinal, y sobre todo es rara en la enfermedad de Crohn, donde presenta ciertas peculiaridades respecto a su clinica habitual, de tal manera que ocurre con mas frecuencia cuando la enfermedad de Crohn es de predominio colonico, suele aparecer un tiempo despues del diagnostico de esta y, ademas, complica el curso clinico de ambas enfermedades. En este trabajo se presenta un caso de enfermedad de Crohn asociada a purpura trombocitopenica idiopatica, en una mujer de 14 anos en la que la purpura trombocitopenica idiopatica se inicio de forma simultanea a la enfermedad de Crohn, con mala evolucion clinica y resistencia a los tratamientos habituales de ambas enfermedades.

13C-urea breath test is one of the best methods for the diagnosis of Helicobacter pylori infection. Although a citric acid solution is generally used prior to urea intake, the superiority of this strategy has not been sufficiently demonstrated. Thus, our aim was to compare 13C-urea breath test with and without citric acid solution, to evaluate whether 13C-urea breath test can also achieve favourable results when the test meal is omitted.13C-urea breath test with and without citric acid were compared prospectively in 53 subjects without prior Helicobacter pylori eradication therapy prescription. Basal samples and at 15', 30', and 45' after taking 100 mg of 13C-urea were obtained. The gold standard for Helicobacter pylori diagnosis was the 13C-urea breath test result with citric acid at 30', and "Delta Over Baseline" values5 at that time were considered positive.The prevalence of Helicobacter pylori infection was 68%. Mean Delta Over Baseline values with citric acid at 15', 30' and 45' were: 29.6+/-39, 30.8+/-37 and 24.6+/-27; whereas respective values without citric acid were lower: 14.9+/-22, 12.2+/-17 and 10D+/-13 (pO. 001 for all comparisons, Wilcoxon test for paired data). Thus, the area under the curve (constructed with Delta Over Baseline values at different times) with citric acid was 85+/- 102, and 37+/-50 without citric acid [p0.001). Correlation coefficient between Delta Over Baseline values with and without citric acid at 30' was 0.73 (p0.0001). The percentage of subjects achieving the highest Delta Over Baseline value at 15', 30' and 45' with citric acid was 51%, 30% and 19%, whereas without citric acid it was 51%, 26% and 23% (non-significant differences). The area under receiver operating characteristic curve for 13C-urea breath test without citric acid was: 0.98 at 15', 1 at 30' and 0.97 at 45'. The best cut-off point for 13C-urea breath test without citric acid at 30' was anywhere between 3. 3 and 3.9 (that is, a lower value than that usually considered with citric acid), with 100% (95% confidence interval, 90-100%) sensitivity and 100% [82-100%) specificity13C-urea breath test values with citric acid are higher than those obtained without citric acid, although this difference does not imply a diagnostic superiority in untreated patients when considering 13C-urea breath test without citric acid at 30'. Therefore, for the diagnosis of Helicobacter pylori infection in untreated patients, citric acid solution in 13C-urea breath test protocol can be omitted.

Background Methotrexate is useful in inflammatory bowel disease (IBD), but its role is secondary because of its limited experience and a supposedly unfavorable safety profile. Aim To describe the efficacy and safety of methotrexate in a long-term real clinical practice. Methods Retrospectively reviewed records of IBD patients treated with methotrexate in eight hospitals of Madrid (Spain). Results A total of 77 patients were included (80% Crohn’s disease); 94% received methotrexate because of steroid dependency. Overall, 82% of the patients initially responded (28% remission). Eighty-eight percent of the patients followed maintenance treatment for a mean of 17 (range: 1–108) months. Forty percent of the patients lost response at a mean of 57 weeks after starting methotrexate. No statistically significant differences were found in the response rates in terms of the disease type, route of administration, or the Montreal Classification category. The mean methotrexate cumulative dose was 1108 mg (range: 25–6480). The main adverse events included 10 cases of gastrointestinal symptoms, four of myelotoxicity, and 10 of abnormal liver function tests, and led to methotrexate withdrawal in four (5%) patients. Transient elastography, performed in 46 patients, detected six additional cases with significant fibrosis and normal liver function tests. Conclusion Methotrexate is useful in inducing a response in IBD, although its efficacy decreases frequently through the follow-up. Although methotrexate seems safe in the long term, in addition to biochemical controls, a more accurate method to detect liver damage should be considered.

Acute tumour lysis syndrome (TLS) is a catastrophic complication of the treatment of certain neoplastic disorders. It most commonly occurs in association with hematologic malignancies and appears a few hours to a few days after initiation of specific chemotherapy, as the result from the release of intracellular components into the bloodstream due to abrupt malignant cell death. Acute spontaneous TLS is rare, and it has been described in leukemia and lymphoma and in some patients with solid tumors prior to institution of therapy. The syndrome is characterized by hyperuricemia, hyperphosphatemia, hypocalcemia, hyperkalemia, and acute oliguric or anuric renal failure due to uric acid precipitation within the tubules (acute uric acid nephropathy) and to calcium phosphate deposition in the renal parenchyma and vessels.We report a case of acute spontaneous TLS in a patient with Crohn s disease treated with immunosuppressive drugs, who developed a plasmocytoma, in which serum uric acid concentration attained exceptionally high levels (44 mg/dL). The patient underwent acute oliguric renal failure, which required treatment with hyperhydration, urine alkalinization, urate oxidase and hemodialysis, with a fatal evolution.In conclusion, the present case report has several peculiarities: that of being one of the rare examples of spontaneous TLS, that of showing an exceptionally severe hyperuricemia, probably the highest ever reported in the literature, and that of the possible increased risk of tumours in patients with Crohn s disease taking inmunosuppressives and/or TNF antagonists.
