We aim to describe the incidence and source of contagion of COVID-19 in patients with IBD, as well as the risk factors for a severe course and long-term sequelae. This is a prospective observational study of IBD and COVID-19 included in the ENEIDA registry (53,682 from 73 centres) between March-July 2020 followed-up for 12 months. Results were compared with data of the general population (National Centre of Epidemiology and Catalonia). A total of 482 patients with COVID-19 were identified. Twenty-eight percent were infected in the work environment, and 48% were infected by intrafamilial transmission, despite having good adherence to lockdown. Thirty-five percent required hospitalization, 7.9% had severe COVID-19 and 3.7% died. Similar data were reported in the general population (hospitalisation 19.5%, ICU 2.1% and mortality 4.6%). Factors related to death and severe COVID-19 were being aged >= 60 years (OR 7.1, 95% CI: 1.8-27 and 4.5, 95% CI: 1.3-15.9), while having >= 2 comorbidities increased mortality (OR 3.9, 95% CI: 1.3-11.6). None of the drugs for IBD were related to severe COVID-19. Immunosuppression was definitively stopped in 1% of patients at 12 months. The prognosis of COVID-19 in IBD, even in immunosuppressed patients, is similar to that in the general population. Thus, there is no need for more strict protection measures in IBD.

Background and aims Crohn's disease [CD] can develop penetrating complications at any time during the disease course. Enterocutaneous fistulae [ECF] are disease-related complications with an important impact on quality of life. Our aim was to describe the outcomes of this complication, including its medical and/or surgical management and their temporal trends. The primary endpoint was fistula closure, defined as the absence of drainage, with no new abscess or surgery, over the preceding 6 months. Methods Clinical information from all adult patients with CD and at least one ECF-excluding perianal fistulae-were identified from the prospectively-maintained ENEIDA registry. All additional information regarding treatment for this complication was retrospectively reviewed. Results A total of 301 ECF in 286 patients [January 1970-September 2020] were analysed out of 30 088 records. These lesions were mostly located in the ileum [67%] and they had a median of one external opening [range 1-10]. After a median follow-up of 146 months (interquartile range [IQR], 69-233), 69% of patients underwent surgery. Fistula closure was achieved in 84%, mostly after surgery, and fistula recurrence was uncommon [13%]. Spontaneous and low-output fistulae were associated with higher closure rates (hazard ratio [HR] 1.51, 95% confidence interval [CI] 1.17-1.93, p = 0.001, and HR 1.49, 95% CI 1.07-2.06, p = 0.03, respectively); this was obtained more frequently with medical therapy since biologics have been available. Conclusions ECF complicating CD are rare but entail a high burden of medical and surgical resources. Closure rates are high, usually after surgery, and fistula recurrence is uncommon. A significant proportion of patients receiving medical therapy can achieve fistula closure.

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

BACKGROUND: Endoscopic balloon dilation (EBD) is the established endoscopic treatment for short strictures in Crohn's disease. Fully covered self-expandable metal stents (FCSEMS) have been used for endoscopic treatment of patients for whom EBD was unsuccessful. We aimed to determine the efficacy and safety of the two endoscopic treatments in patients with Crohn's disease with stenosis and compare the mean cost of both treatments.; METHODS: This multicentre, open-label, randomised trial was done in 19 tertiary and secondary hospitals in Spain. Patients with Crohn's disease with obstructive symptoms and predominantly fibrotic strictures of less than 10 cm in length were eligible for inclusion. We excluded patients with stenosis treated with SEMS or EBD in the previous year and stenosis not accessible to a colonoscope. Patients were randomly assigned (1:1) to receive either EBD (EBD group) or FCSEMS (FCSEMS group) using a digital en-block randomisation system (block size of four). In the EBD group, dilation was done with a CRE Boston Scientific (Marlborough, MA, USA) pneumatic balloon with the diameter set at the discretion of the endoscopist; a maximum of two sessions of dilation were allowed with a minimum interval of 15-30 days between them. In the FCSEMS group, a 20 mm diameter Taewoong (Gimpo-si, South Korea) fully covered metal stent was placed; stent length was set at the discretion of the endoscopist. The primary outcome was to assess the efficacy of the endoscopic treatment, defined by the proportion of patients free of a new therapeutic intervention (EBD, FCSEMS, or surgery) due to symptomatic recurrence at 1 year of follow-up. Patients were analysed according to the intention-to-treat principle. Adverse events were recorded for all the patients; events were considered associated to be with the procedure when a causal association was possible, probable, or definite. This trial is registered with ClinicalTrials.gov, NCT02395354.; FINDINGS: From Aug 28, 2013, to Oct 9, 2017, we assessed the eligibility of 99 patients, of whom 19 (19%) patients were excluded. Thus, 80 (81%) patients were randomly assigned to treatment: 39 (49%) patients to the FCSEMS group and 41 (51%) patients to the EBD group. 33 (80%) of 41 patients in the EBD group and 20 (51%) of 39 patients in the FCSEMS group were free of a new therapeutic intervention at 1 year (odds ratio [OR] 3·9 [95% CI 1·4-10·6]; p=0·0061). Two (3%) of 80 patients had severe adverse events (one [2%] patient in the EBD group and one [3%] patient in the FCSEMS group); both patients had perforations.; INTERPRETATION: EBD is more effective than FCSEMS for Crohn's disease strictures, with a good safety profile for both treatments.; FUNDING: Spanish National Institute of Health, Foundation of Spanish Society of Digestive Endoscopy, Catalan Society of Gastroenterology, and Taweoong.

Background Methotrexate can be used to maintain remission in Crohn's disease patients who are intolerant to thiopurines. Data on its use as monotherapy in other scenarios are limited. Aim To assess the effectiveness of methotrexate monotherapy in Crohn's disease patients after previous failure to anti-tumour necrosis factor (anti-TNF alpha) drugs. Methods A retrospective, observational multicentre study of data from the Spanish ENEIDA registry. Participants were patients with active Crohn's disease and previous failure to anti-TNF alpha started on methotrexate monotherapy. Short-term effectiveness was assessed at 12-16 weeks based on Harvey-Bradshaw index (HBI): clinical remission as HBI = 3 points over baseline. Long-term effectiveness was defined as steroid-free methotrexate persistence from 12 to 16 weeks until maximum follow up. Adverse events were recorded. Results Data were compiled for 110 patients treated with methotrexate after a failed response to one (39%) or two (55.6%) anti-TNF alpha agents. Short-term clinical response and remission rates were 60% and 30.9% respectively. Of 74 patients who continued after week 16, long-term effectiveness was achieved in 82% and 74% at 12 and 24 months respectively. In the multivariate analysis, non-remission at short term (vs remission) was associated with long-term failure (HR 2.58, 95%CI 1.95-3.68, P = 0.028). Adverse events (evaluated in 100 patients) were recorded in 44%, and in 30.4% of these patients, they led to methotrexate discontinuation. Conclusions The benefits observed suggest methotrexate monotherapy could be a valid option in Crohn's disease patients with previous failure to anti-TNF alpha.

OBJECTIVE: No studies evaluating the rapidity of response to biological therapies are available for Crohn's disease (CD). The aim of this study was to evaluate rapidity of onset of clinical response and impact on quality of life (QoL) of adalimumab therapy in adult anti-TNF-naïve patients with moderately-to-severely active CD. PATIENTS AND METHODS: RAPIDA was an open-label, single-arm, prospective, multicenter clinical trial. Adult patients with moderately-to-severely active luminal CD, anti-TNF-naïve, and unresponsive to conventional therapy were treated with adalimumab. Clinical disease activity, QoL and inflammatory biomarkers were measured at day 4, and weeks 1, 2, 4, and 12 after treatment initiation. RESULTS: Eighty-six patients were included in the intention-to-treat (ITT) analyses. Clinical disease activity was reduced from a median of 9.0 points to 6.0 points at day 4. Clinical response (= 3-point reduction in the Harvey-Bradshaw Index, HBI) was achieved by 61.6% (d4) and 75.6% (w1) of patients in the ITT population (median 2.5 days) and with non-responder imputation (NRI), by 55.8% and 53.4%, respectively. The proportion of patients in clinical remission (HBI
