Immigrant IBD Patients in Spain Are Younger, Have More Extraintestinal Manifestations and Use More Biologics Than Native Patients.

BACKGROUND: Previous studies comparing immigrant ethnic groups and native patients with IBD have yielded clinical and phenotypic differences. To date, no study has focused on the immigrant IBD population in Spain. METHODS: Prospective, observational, multicenter study comparing cohorts of IBD patients from ENEIDA-registry who were born outside Spain with a cohort of native patients. RESULTS: We included 13,524 patients (1,864 immigrant and 11,660 native). The immigrants were younger (45 ± 12 vs. 54 ± 16 years, p < 0.001), had been diagnosed younger (31 ± 12 vs. 36 ± 15 years, p < 0.001), and had a shorter disease duration (14 ± 7 vs. 18 ± 8 years, p < 0.001) than native patients. Family history of IBD (9 vs. 14%, p < 0.001) and smoking (30 vs. 40%, p < 0.001) were more frequent among native patients. The most prevalent ethnic groups among immigrants were Caucasian (41.5%), followed by Latin American (30.8%), Arab (18.3%), and Asian (6.7%). Extraintestinal manifestations, mainly musculoskeletal affections, were more frequent in immigrants (19 vs. 11%, p < 0.001). Use of biologics, mainly anti-TNF, was greater in immigrants (36 vs. 29%, p < 0.001). The risk of having extraintestinal manifestations [OR: 2.23 (1.92-2.58, p < 0.001)] and using biologics [OR: 1.13 (1.0-1.26, p = 0.042)] was independently associated with immigrant status in the multivariate analyses. CONCLUSIONS: Compared with native-born patients, first-generation-immigrant IBD patients in Spain were younger at disease onset and showed an increased risk of having extraintestinal manifestations and using biologics. Our study suggests a featured phenotype of immigrant IBD patients in Spain, and constitutes a new landmark in the epidemiological characterization of immigrant IBD populations in Southern Europe.

The EPAGE guidelines are not an effective strategy for managing colonoscopies during the COVID-19 pandemic. / EPAGE no es una estrategia eficaz para la gestión de colonoscopias durante la pandemia por COVID-19.

INTRODUCTION: The pandemic caused by the SARS-CoV-2 virus has had a serious impact on the functioning of gastrointestinal endoscopy Units. The Asociación Española de Gastroenterología (AEG) and the Sociedad Española de Endoscopia Digestiva (SEED) have proposed the EPAGE guidelines for managing postponed colonoscopies. OBJECTIVE: To evaluate the EPAGE guidelines as a management tool compared to the immunologic faecal occult blood test (iFOBT) and compared to risk score (RS) that combines age, sex and the iFOBT for the detection of colorectal cancer (CRC) and significant bowel disease (SBD). METHODS: A prospective, single-centre study enrolling 743 symptomatic patients referred for a diagnostic colonoscopy. Each order was classified according to the EPAGE guidelines as appropriate, indeterminate or inappropriate. Patients underwent an iFOBT and had their RS calculated. RESULTS: The iFOBT (p<0.001), but not the EPAGE guidelines (p = 0.742), was an independent predictive factor of risk of CRC. The ROC AUCs for the EPAGE guidelines, the iFOBT and the RS were 0.61 (95% CI 0.49-0.75), 0.95 (0.93-0.97) and 0.90 (0.87-0.93) for CRC, and 0.55 (0.49-0.61), 0.75 (0.69-0.813) and 0.78 (0.73-0.83) for SBD, respectively. The numbers of colonoscopies needed to detect a case of CRC and a case of SBD were 38 and seven for the EPAGE guidelines, seven and two for the iFOBT, and 19 and four for a RS ≥5 points, respectively. CONCLUSION: The EPAGE guidelines, unlike the iFOBT, is not suitable for screening candidate patients for a diagnostic colonoscopy to detect CRC. The iFOBT, in combination with age and sex, is the most suitable strategy for managing demand for endoscopy in a restricted-access situation.

Effectiveness and Safety of Ustekinumab in Ulcerative Colitis: Real-world Evidence from the ENEIDA Registry.

BACKGROUND AND AIMS: The development programm UNIFI has shown promising results of ustekinumab in ulcerative colitis [UC] treatment which should be confirmed in clinical practice. We aimed to evaluate the durability, effectiveness, and safety of ustekinumab in UC in real life. METHODS: Patients included in the prospectively maintained ENEIDA registry, who received at least one intravenous dose of ustekinumab due to active UC [Partial Mayo Score [PMS]>2], were included. Clinical activity and effectiveness were defined based on PMS. Short-term response was assessed at Week 16. RESULTS: A total of 95 patients were included. At Week 16, 53% of patients had response [including 35% of patients in remission]. In the multivariate analysis, elevated serum C-reactive protein was the only variable significantly associated with lower likelihood of achieving remission. Remission was achieved in 39% and 33% of patients at Weeks 24 and 52, respectively; 36% of patients discontinued the treatment with ustekinumab during a median follow-up of 31 weeks. The probability of maintaining ustekinumab treatment was 87% at Week 16, 63% at Week 56, and 59% at Week 72; primary failure was the main reason for ustekinumab discontinuation. No variable was associated with risk of discontinuation. Three patients reported adverse events; one of them had a fatal severe SARS-CoV-2 infection. CONCLUSIONS: Ustekinumab is effective in both the short and the long term in real life, even in a highly refractory cohort. Higher inflammatory burden at baseline correlated with lower probability of achieving remission. Safety was consistent with the known profile of ustekinumab.

Effectiveness and safety of methotrexate monotherapy in patients with Crohn's disease refractory to anti-TNF-α: results from the ENEIDA registry.

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-TNFα) 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-TNFα 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 and clinical response as HBI drop of ≥ 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-TNFα 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-TNFα.

The use of faecal immunochemical testing in the decision-making process for the endoscopic investigation of iron deficiency anaemia.

Background Blood loss from the gastrointestinal (GI) tract is the most common cause of iron deficiency anaemia (IDA) in adult men and postmenopausal women. Gastroduodenal endoscopy (GDE) and colonoscopy are frequently recommended, despite uncertainty regarding the coexistence of lesions in the upper and lower GI tract. The faecal immunochemical test (FIT) measures the concentration of faecal haemoglobin (f-Hb) originating only from the colon or rectum. We aimed to assess whether the FIT was able to select the best endoscopic procedure for detecting the cause of IDA. Methods A prospective study of 120 men and postmenopausal women referred for a diagnostic study of IDA were evaluated with an FIT, GDE and colonoscopy. The endoscopic finding of a significant upper lesion (SUL) or a significant bowel lesion (SBL) was considered to be the cause of the IDA. Results The diagnoses were 35.0% SUL and 20.0% SBL, including 13.3% GI cancer. In the multivariate analysis, the concentration of blood haemoglobin (b-Hb) <9 g/dL (OR: 2.60; 95% CI 1.13-6.00; p = 0.025) and non-steroidal anti-inflammatory drugs NSAIDs (2.56; 1.13-5.88; p = 0.024) were associated with an SUL. Age (0.93; 0.88-0.99; p = 0.042) and f-Hb ≥ 15 µg Hb/g faeces (38.53; 8.60-172.50; p < 0.001) were associated with an SBL. A "FIT plus gastroscopy" strategy, in which colonoscopy is performed only when f-Hb ≥15 µg Hb/g faeces, would be able to detect 92.4% of lesions and be 100% accurate in the detection of cancer while avoiding 71.6% of colonoscopies. Conclusions The FIT is an accurate method for selecting the best endoscopy study for the evaluation of IDA. An FIT-based strategy is more cost-effective than the current bidirectional endoscopy-based strategy and could improve endoscopic resource allocation.

Clinical Characteristics, Associated Malignancies and Management of Primary Sclerosing Cholangitis in Inflammatory Bowel Disease Patients: A Multicentre Retrospective Cohort Study.

BACKGROUND AND AIMS: Primary sclerosing cholangitis [PSC] is usually associated with inflammatory bowel disease [IBD]. An increased risk of malignancies, mainly colorectal cancer [CRC] and cholangiocarcinoma [CCA], has been reported in PSC-IBD patients. Our aim was to determine the clinical characteristics and management of PSC in IBD patients, and the factors associated with malignancies. METHODS: PSC-IBD patients were identified from the Spanish ENEIDA registry of GETECCU. Additional data were collected using the AEG-REDCap electronic data capture tool. RESULTS: In total, 277 PSC-IBD patients were included, with an incidence rate of 61 PSC cases per 100 000 IBD patient-years, 69.7% men, 67.5% ulcerative colitis and mean age at PSC diagnosis of 40 ± 16 years. Most patients [85.2%] were treated with ursodeoxycholic acid. Liver transplantation was required in 35 patients [12.6%] after 79 months (interquartile range [IQR] 50-139). It was more common in intra- and extrahepatic PSC compared with small-duct PSC (16.3% vs 3.3%; odds ratio [OR] 5.7: 95% confidence interval [CI] = 1.7-19.3). The incidence rate of CRC since PSC diagnosis was 3.3 cases per 1000 patient-years [95% CI = 1.9-5.6]. Having symptoms of PSC at PSC diagnosis was the only factor related to an increased risk of CRC after IBD diagnosis [hazard ratio= 3.3: 95% CI = 1.1-9.9]. CCA was detected in seven patients [2.5%] with intra- and extrahepatic PSC, with median age of 42 years [IQR 39-53], and presented a lower life expectancy compared with patients without CCA and patients with or without CRC. CONCLUSIONS: PSC-IBD patients with symptoms of PSC at PSC diagnosis have an increased risk of CRC. CCA was only diagnosed in patients with intra- and extrahepatic PSC and was associated with poor survival.
