Benefits of Paediatric to Adult Transition Programme in Inflammatory Bowel Disease: The BUTTERFLY Study of GETECCU and SEGHNP.

(1) Background: Transition is a planned movement of paediatric patients to adult healthcare systems, and its implementation is not yet established in all inflammatory bowel disease (IBD) units. The aim of the study was to evaluate the impact of transition on IBD outcomes. (2) Methods: Multicentre, retrospective and observational study of IBD paediatric patients transferred to an adult IBD unit between 2017-2020. Two groups were compared: transition (≥1 joint visit involving the gastroenterologist, the paediatrician, a programme coordinator, the parents and the patient) and no-transition. Outcomes within one year after transfer were analysed. The main variable was poor clinical outcome (IBD flare, hospitalisation, surgery or any change in the treatment because of a flare). Predictive factors of poor clinical outcome were identified with multivariable analysis. (3) Results: A total of 278 patients from 34 Spanish hospitals were included. One hundred eighty-five patients (67%) from twenty-two hospitals (65%) performed a structured transition. Eighty-nine patients had poor clinical outcome at one year after transfer: 27% in the transition and 43% in the no-transition group (p = 0.005). One year after transfer, no-transition patients were more likely to have a flare (36% vs. 22%; p = 0.018) and reported more hospitalisations (10% vs. 3%; p = 0.025). The lack of transition, as well as parameters at transfer, including IBD activity, body mass index < 18.5 and corticosteroid treatment, were associated with poor clinical outcome. One patient in the transition group (0.4%) was lost to follow-up. (4) Conclusion: Transition care programmes improve patients' outcomes after the transfer from paediatric to adult IBD units. Active IBD at transfer impairs outcomes.

Ustekinumab and vedolizumab for the prevention of postoperative recurrence of Crohn's disease: Results from the ENEIDA registry.

BACKGROUND: Anti-TNF agents are the only effective biological agents for the prevention of postoperative recurrence (POR) in Crohn's disease (CD). However, they are contraindicated or have been shown to fail in some patients. Although ustekinumab and vedolizumab were licensed for CD some years ago, data in this setting are scarce. METHODS: All CD patients in whom ustekinumab or vedolizumab was prescribed for the prevention of POR within three months of ileocolonic resection with anastomosis were identified from the ENEIDA registry. The development of endoscopic, clinical and surgical POR was registered. RESULTS: Forty patients were treated for the prevention of POR with ustekinumab and 25 were treated with vedolizumab. Eighty per cent had at least one risk factor for POR (prior resections, active smoking, perianal disease or penetrating disease behaviour). All the patients had been exposed to anti-TNF therapy. After a median follow-up of 17 and 26 months, the cumulative probability of clinical POR at 12 months after surgery was 32% and 30% for ustekinumab and vedolizumab, respectively. Endoscopic assessment within the first 18 months after surgery was available for 80% of the patients on ustekinumab and 70% for those on vedolizumab. The rate of endoscopic POR was 42% for ustekinumab and 40% for vedolizumab. One patient treated with ustekinumab and two with vedolizumab underwent a new intestinal resection. CONCLUSIONS: Ustekinumab and vedolizumab seem to be effective in the prevention of POR in patients at high risk. Our results warrant controlled trials comparing these drugs with conventional therapies.

Risk Factors for COVID-19 in Inflammatory Bowel Disease: A National, ENEIDA-Based Case-Control Study (COVID-19-EII).

(1) Scant information is available concerning the characteristics that may favour the acquisition of COVID-19 in patients with inflammatory bowel disease (IBD). Therefore, the aim of this study was to assess these differences between infected and noninfected patients with IBD. (2) This nationwide case−control study evaluated patients with inflammatory bowel disease with COVID-19 (cases) and without COVID-19 (controls) during the period March−July 2020 included in the ENEIDA of GETECCU. (3) A total of 496 cases and 964 controls from 73 Spanish centres were included. No differences were found in the basal characteristics between cases and controls. Cases had higher comorbidity Charlson scores (24% vs. 19%; p = 0.02) and occupational risk (28% vs. 10.5%; p < 0.0001) more frequently than did controls. Lockdown was the only protective measure against COVID-19 (50% vs. 70%; p < 0.0001). No differences were found in the use of systemic steroids, immunosuppressants or biologics between cases and controls. Cases were more often treated with 5-aminosalicylates (42% vs. 34%; p = 0.003). Having a moderate Charlson score (OR: 2.7; 95%CI: 1.3−5.9), occupational risk (OR: 2.9; 95%CI: 1.8−4.4) and the use of 5-aminosalicylates (OR: 1.7; 95%CI: 1.2−2.5) were factors for COVID-19. The strict lockdown was the only protective factor (OR: 0.1; 95%CI: 0.09−0.2). (4) Comorbidities and occupational exposure are the most relevant factors for COVID-19 in patients with IBD. The risk of COVID-19 seems not to be increased by immunosuppressants or biologics, with a potential effect of 5-aminosalicylates, which should be investigated further and interpreted with caution.

Association of golimumab trough concentrations during maintenance with clinical, biological, endoscopic and histologic remission in patients with ulcerative colitis.

BACKGROUND: Optimal golimumab concentration thresholds for important outcomes during maintenance are lacking. AIMS: To investigate the association of golimumab trough concentrations during maintenance with key outcomes, including endoscopic and histologic remission, and long-term event-free persistence with golimumab, in patients with UC. METHODS: This multi-centre, cross-sectional study included patients with UC on golimumab maintenance recruited either in remission or during a flare. Colonoscopy was scheduled, and study-specific rectocolonic biopsies were taken for blind central histologic reading. Samples for golimumab trough concentrations were collected close to colonoscopy. RESULTS: Fifty-two patients were included. Median golimumab trough concentrations (µg/ml) were significantly higher in patients who had clinical remission (2.01 vs. 0.72, p = 0.047), combined clinical-biochemical remission (PMS ≤2 + faecal calprotectin <250 µg/g) (2.21 vs. 1.47, p = 0.041), endoscopic healing (Mayo endoscopic subscore 0) (2.52 vs. 1.47, p = 0.003), histologic remission (Geboes index ≤2.0) (2.33 vs. 1.50, p = 0.02) and disease clearance (clinical remission endoscopic healing + histologic remission) (2.52 vs. 1.70, p = 0.009), compared with those not meeting these criteria. Golimumab concentrations were significantly higher in patients who avoided golimumab dose escalation/discontinuation during follow-up (2.24 vs. 0.98, p = 0.012). Receiver-operating characteristic analyses identified golimumab thresholds [area under the curve] of 0.85 [0.76], 1.90 [0.76], 2.29 [0.75], 1.79 [0.68], 2.29 [0.72] and 1.56 [0.71] µg/ml as associated with clinical remission, combined remission, endoscopic healing, histologic remission, disease clearance and long-term event-free persistence with golimumab, respectively. CONCLUSIONS: Golimumab trough concentrations during maintenance are associated with favourable treatment outcomes including endoscopic healing, histologic remission and long-term persistence on golimumab. We identified the optimal golimumab thresholds most closely associated with key outcomes.

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.

Nationwide COVID-19-EII Study: Incidence, Environmental Risk Factors and Long-Term Follow-Up of Patients with Inflammatory Bowel Disease and COVID-19 of the ENEIDA Registry.

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.

Evaluation of changes in intestinal microbiota in Crohn's disease patients after anti-TNF alpha treatment.

Intestinal dysbiosis is key in the onset and development of Crohn's disease (CD). We evaluated the microbiota changes in CD patients before and after a six-month anti-TNF treatment, comparing these changes with the microbiota of healthy subjects. This prospective multicenter observational study involved 27 CD patients initiating anti-TNF treatment and 16 healthy individuals. Inflammatory activity was determined at baseline, 3 and 6 months, classifying patients into responders and non-responders. Fecal microbiota was analyzed by massive genomic sequencing thought 16S rRNA amplicon sequencing before and after six months of anti-TNF treatment. The CD cohort showed a decrease in genera of the class Clostridia, short-chain fatty acid producers, and an increase in the phylum Proteobacteria (p < 0.01) versus the healthy cohort. After anti-TNF treatment, the phylum Proteobacteria also increased in non-responders versus responders (13/27) (p < 0.005), with the class Clostridia increasing. In addition, alpha diversity increased in responders versus non-responders (p < 0.01), tending towards eubiosis. An association was found (p < 0.001) in the F.prausnitzii/E.coli ratio between responders and non-responders. The F/E ratio was the most accurate biomarker of anti-TNF response (area under the curve 0.87). Thus, anti-TNF treatment allows partial restoration of intestinal microbiota in responders and the F.prausnitzii/E.coli ratio can provide a reliable indicator of response to anti-TNF in CD.

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.

Tofacitinib in Ulcerative Colitis: Real-world Evidence From the ENEIDA Registry.

AIM: To evaluate the effectiveness and safety of tofacitinib in ulcerative colitis [UC] in real life. METHODS: Patients from the prospectively maintained ENEIDA registry and treated with tofacitinib due to active UC were included. Clinical activity and effectiveness were defined based on Partial Mayo Score [PMS]. Short-term response/remission was assessed at Weeks 4, 8, and 16. RESULTS: A total of 113 patients were included. They were exposed to tofacitinib for a median time of 44 weeks. Response and remission at Week 8 were 60% and 31%, respectively. In multivariate analysis, higher PMS at Week 4 (odds ratio [OR] = 0].2; 95% confidence interval [CI] = 0].1-0.4) was the only variable associated with lower likelihood of achieving remission at Week 8. Higher PMS at Week 4 [OR = 0.5; 95% CI = 0.3-0.7] and higher PMS at Week 8 [OR = 0.2; 95% CI = 0.1-0.5] were associated with lower probability of achieving remission at Week 16. A total of 45 patients [40%] discontinued tofacitinib over time. Higher PMS at Week 8 was the only factor associated with higher tofacitinib discontinuation [hazard ratio = 1.5; 95% CI = 1.3-1.6]. A total of 34 patients had remission at Week 8; of these, 65% had relapsed 52 weeks after achieving remission; the dose was increased to 10 mg/12 h in nine patients, and five of them reached remission again. Seventeen patients had adverse events. CONCLUSIONS: Tofacitinib is effective and safe in UC patients in real practice, even in a highly refractory cohort. A relevant proportion of patients discontinue the drug over time, mainly due to primary failure.

Vedolizumab, una opción en pacientes con enfermedad inflamatoria intestinal intolerantes a tiopurinas y refractarios a biológicos / Vedolizumab, an option in patients with inflammatory bowel disease intolerant to thiopurines and refractory to biological agents

Vedolizumab (VDZ), un anticuerpo monoclonal humanizado que se une específicamente a -alpha4beta7-integrina, aprobado para el tratamiento de la enfermedad de Crohn (EC) y la colitis ulcerosa (CU), ha demostrado su eficacia en ensayos clínicos controlados. OBJETIVO: Describir una población tratada con VDZ y evaluar su efectividad y seguridad a largo plazo en práctica clínica. MÉTODOS: Estudio observacional y multicéntrico en pacientes con enfermedad inflamatoria intestinal tratados con VDZ durante al menos un año. Se evaluaron los índices de actividad, niveles de calprotectina fecal y proteína C reactiva, hospitalizaciones, cirugías y eventos adversos. RESULTADOS: Se analizaron un total de 73 pacientes (43 CU y 30 EC). El 74 y 23% de CU y el 90 y 37% de EC habían llevado previamente más de un anti-TNF y más de un inmunosupresor respectivamente. VDZ se suspendió en 17 pacientes (23%), 10 CU y 7 EC, debido a la falta o pérdida de respuesta antes del primer año o a eventos adversos. Veintisiete (63%) CU y 16 (53%) pacientes con EC requirieron intensificación de la dosis. A los 6 meses, el 70 y 42% de CU y el 80 y 43% de EC lograron respuesta clínica y remisión respectivamente. Al año, el 58 y 35% de CU y el 47 y 43% de EC mantuvieron la respuesta clínica y la remisión, respectivamente. La proteína C reactiva disminuyó significativamente tanto en la EC como en la CU. Sin embargo, la disminución de la calprotectina fecal se logró durante el seguimiento solo en CU pero no en EC. Ocho pacientes con EC que habían sido tratados previamente con ustekinumab evitaron la cirugía al año. En 8 CU (18,6%) se realizó colectomía y 4 EC (13,3%) necesitaron cirugía. Seis pacientes (8%) (5 UC y una enfermedad de Crohn) tuvieron eventos adversos. El uso concomitante de corticoides o inmunomoduladores no aumentó la efectividad. A mayor número de anti-TNF previos, menos remisión en la CU y respuesta en la EC. CONCLUSIONES: Tras un año de VDZ se induce respuesta y remisión clínica en una no desdeñable proporción de pacientes refractarios a diferentes biológicos o inmunosupresores. VDZ puede considerarse una alternativa en intolerantes a inmunosupresores con pocos eventos adversos

Vedolizumab (VDZ), a human monoclonal antibody that binds specifically to alpha4beta7-integrin, and is approved for the treatment of Crohn's disease (CD) and ulcerative colitis (UC), has demonstrated its efficacy in controlled clinical trials. OBJECTIVE: To describe a population treated with VDZ and to evaluate its long-term efficacy and safety in clinical practice. METHODS: An observational and multicentre study was carried out on patients with inflammatory bowel disease treated with VDZ for at least one year. An evaluation was performed on the activity indices, faecal calprotectin and C-reactive protein levels, hospital admissions, surgeries, and adverse events. RESULTS: A total of 73 patients were analysed (43 UC and 30 CD). More than one anti-TNF and more than one immunosuppressive was previously used by 74 and 23%, respectively, of UC patients, and 90 and 37%, respectively of CD patients. VDZ was stopped in 17 (23%) patients, 10 UC and 7 CD, due to a lack or loss of response before the first year, or due to adverse events. An intensification of the dose was required in 26 (63%) UC, and 16 (53%) CD patients. At 6 months, 70 and 42% of UC patients, and 80 and 43% of CD patients achieved a clinical response and remission, respectively. At one year, 58 and 35% of UC patients and 47 and 43% of CD patients, maintained the clinical response and remission, respectively. The C-reactive protein decreased significantly in both CD and UC patients. However, the decrease in faecal calprotectin was only achieved during follow-up in UC, but not in CD patients. Eight patients with CD that had been treated previously with ustekinumab avoided surgery at one year. A colectomy was performed on 8 (18.6%) UC patients, and 4 (13.3%) CD patients needed surgery. Six patients (8%) (5 UC and 1 CD) had adverse events. The concomitant use of corticosteroids or immunomodulators did not increase the efficacy. Those with a higher number of previous anti-TNF treatments showed less remissions in UC and responses in CD. CONCLUSIONS: After one year of VDZ, a clinical response and remission was induced in a considerable percentage of patients refractory to different biological or immunosuppressive therapies. VDZ can be considered as an alternative in those intolerant to immunosuppressives, with few adverse events
