RESUMEN
AIMS: The aim of the study is to evaluate the clinical and biochemical response of inflammatory bowel disease patients treated with vedolizumab, 16 weeks after transitioning from intravenous (iv) to subcutaneous (sc). METHODS: An observational, prospective, single-center cohort study was performed. Patients with inflammatory bowel disease and maintenance treatment with vedolizumab, stable for at least 4 months, were offered to switch to sc formulation. At the same time of treatment administration a blood test was performed, with vedolizumab levels and fecal calprotectin. RESULTS: Forty-three patients were included, 12 of them (27.9%) chose to transition to sc formulation. All included patients remained in remission during follow-up. At week 16 no significant differences were found in terms of calprotectin levels in patients on iv treatment (mean 146.6±SD 45.9) vs. sc (159.26±53.9) (p=0.9). Vedolizumab serum levels at week 16 were higher in the sc group (22,364.3±5141.6) vs. iv (11,425.9±1514.2) (p=0.009). At week 16, 9 (75%) of the patients in the sc group were highly satisfied with the medication and 11 (91.7%) considered it easy to administer. Four patients (12.9%) in the iv group and 2 (16.6%) in the sc group presented mild adverse effects. The 2 cases (100%) of the sc group the adverse event was local inflammation at the injection site. CONCLUSION: In our experience, vedolizumab sc is a convenient alternative to iv administration. Vedolizumab serum levels in patients who transitioned to sc were higher than iv formulation.
RESUMEN
BACKGROUND: Data regarding bowel preparation in patients with Inflammatory Bowel Disease (IBD) are scarce. AIM: To compare efficacy, safety, and tolerability of low-volume preparations in patients with IBD. METHODS: Single-center, randomized, prescriber, and colonoscopist-blinded clinical trial. IBD outpatients undergoing colonoscopy were randomized 1:1:1 to receive 1 Liter-polyethylene glycol-ascorbate (1L-PEG), 2 Liters-PEG, or sodium picosulfate (SP). The primary endpoint was percentage of quality cleansing assessed via the Boston Bowel Preparation Scale (BBPS ≥6, segments ≥2). Secondary endpoints were total high quality cleansing (BBPS 8 or 9), high-quality segmental BBPS (≥2), and patients' tolerability, symptoms, and satisfaction, assessed by questionnaires. Safety was monitored by adverse event reporting, laboratory evaluation at colonoscopy, and telephonic follow-up. RESULTS: Ninety-two patients were included (33 1L-PEG, 28 2L-PEG, and 31 SP). No significant differences between preparations were observed in quality or high-quality total BBPS or high-quality segmental BBPS. Complete intake of the solution was higher for SP (p = 0.006) and lower for 1L-PEG (p = 0.02) compared to 2L-PEG intake (p = 0.55). Clinically irrelevant hyponatremia was higher in the SP group (p < 0.0001). SP instructions were easier to understand from patient's point of view (p = 0.01). Willingness to retake was higher with SP (p < 0.0001) and less for 1L-PEG (p < 0.0001). No serious adverse events were reported. CONCLUSIONS: We observed no differences in efficacy between low-volume preparations in patients with IBD. Complete intake was higher for SP and lower for 1L-PEG. SP and 2L-PEG instructions were better understood and graded, and SP was more likely to be retaken. Willingness to retake was lower for 1L-PEG. No serious adverse events were reported. SUMMARY: No differences in terms of efficacy were regarded in this clinical trial comparing low-volume preparations for colonoscopy in patients with IBD: however, Sodium Pisoculfate is better tolerated and accepted from patient's point of view. No serious adverse events were reported.

BACKGROUND AND AIMS: response to the SARS-CoV-2 vaccine can be altered in patients with immune-mediated diseases, such as inflammatory bowel disease, and in patients under immunosuppressive treatment. The aims of this study were to evaluate the serologic response to the SARS-CoV-2 vaccine in patients with inflammatory bowel disease, to analyze the influence of immunosuppressive drugs on response, and to describe any adverse events in this population. METHODS: this was a prospective study that included adult patients with inflammatory bowel disease. Baseline characteristics, concomitant treatments and previous COVID-19 symptoms were collected. Patients underwent serological testing before the first and after the second vaccine dose. RESULTS: a total of 265 patients were consecutively included. Patients received one of the following vaccines: messenger RNA vaccines from Pfizer/BioNTech and Moderna; and adenovirus vaccines from AstraZeneca and Janssen. All adverse events were mild, and the most frequent was injection site pain in 141 (86 %) patients. The seroconversion rate according to the treatment that patients were receiving was: 100 % for those without treatment, 92.5 % for patients treated with mesalazine, 90.3 % for those receiving immunomodulators, 88.9 % for patients with biological monotherapy and 92.5 % for patients on combined treatment. The generation of antibodies according to the vaccine administered was: Pfizer 92.9 %, Moderna 93.3 %, AstraZeneca 98.4 %, and Janssen 12.5 %. CONCLUSION: the antibody response after vaccination against SARS-CoV-2 is high in patients with inflammatory bowel disease. However, patients treated with immunosuppressive or biologic drugs had a lower response. Adverse events were frequent, but not serious.

INTRODUCTION: Chronic immune-mediated diseases, including inflammatory bowel disease (IBD), present an increased risk of developing early atherosclerosis and cardiovascular events (CVE) at early age. OBJECTIVE: To describe the baseline and 1-year cardiovascular profile of patients with IBD according to the biologic treatment received, taking into account the inflammatory activity. PATIENTS AND METHODS: It is a retrospective, observational study that included 374 patients. Cardiovascular risk factors (CVRF) and CVE were collected at the baseline visit and at one-year follow-up to describe the cardiovascular risk according to the biological treatment received, also assessing clinical and biological remission. RESULTS: A total of 374 patients were included: 146 (38.73%) were treated with Infliximab, 128 (33.95%) with adalimumab, 61 (16.18%) with ustekinumab and 42 (11.14%) with vedolizumab. The changes in blood glucose levels are [86.31mg/dL (84.57-88.06) vs. 89.25mg/dL (87.54-90.96), P=.001] for those treated with antiTNFα and [86.52mg/dL (83.48-89.55) vs. 89.44mg/dL (85.77-93.11), P=.11] in the other group. In the group treated with antiTNFα total cholesterol values at baseline visit are [169.40mg/dL (164.97-173.83) vs. 177.40mg/dL (172.75-182.05) at one year of treatment, P=<.001], those of HDL [50.22mg/dL (48.39-52.04) vs. 54.26mg/dL (52.46-56.07), P=<.001] and those of triglycerides [114.77mg/dL (106.36-123.18) vs. 121.83mg/dL (112.11-131.54), P=.054]. Regarding weight, an increase was observed, both in those patients treated with antiTNFα [71.39kg (69.53-73.25) vs. 72.87kg (71.05-74.70), P<.001], and in the group treated with ustekinumab and vedolizumab [67.59kg (64.10-71.08) vs. 69.43kg (65.65-73.04), P=.003]. Concerning CVE, no significant differences were observed neither according to the drug used (p=0.36), nor according to personal history of CVE (P=.23) nor according to inflammatory activity (P=.46). CONCLUSIONS: Our results on a real cohort of patients with IBD treated with biologic drugs show a better control of certain cardiovascular parameters such as CRP or HDL, but a worsening of others such as total cholesterol or triglycerides, regardless of the treatment. Therefore, it is possibly the disease control and not the therapeutic target used, the one that affect the cardiovascular risk of these patients.

OBJECTIVE: Intestinal ultrasound is considered to be a valid alternative for the evaluation of post-operative recurrence (POR) of Crohn's disease. The aim of this study is to assess the correlation between ultrasound and endoscopic findings. METHODS: Patients with Crohn's disease were retrospectively recruited who had undergone ileocecal resection, and for whom a colonoscopy and intestinal ultrasound had been performed for the detection of POR. Recurrence was assessed using the Rutgeerts score (RS). The ultrasound findings analysed were bowel wall thickness (BWT), parietal hyperaemia using power Doppler, loss of layer pattern and mesenteric fat hypertrophy. RESULTS: A total of 31 patients were included, of which 15 (48.4%) had no POR (RS<2b) and 16 (51.6%) had POR (RS≥2b). A statistically significant association was identified between BWT and the presence of endoscopic recurrence (a mean of 2.75mm vs. 5.68mm, P>0.001). There was also a statistically significant difference in hyperaemia between the 2groups (P=0.03). For wall thickness, an area under the ROC curve (AUC) of 92.9% was obtained, and with a cut-off point of 3.4mm, a sensitivity of 100% and specificity of 86.6%. When comparing with the most frequent biomarkers (fecal calprotectin and serum CRP), a higher AUC was obtained for wall thickness (72.3% and 72.3% vs. 92.9%). CONCLUSIONS: In our experience, ultrasound has high diagnostic efficacy in the detection of POR and can be considered a valid non-invasive alternative to endoscopy.

Bakground and Aim: Predictors of the need for surgery in sticturing Crohn's disease (SCD) are lacking. Bowel ultrasound (US) is a harmless, noninvasive, and inexpensive diagnostic procedure that has proven to be a valuable tool in the management of Crohn's disease (CD). Our aim was to identify ultrasonographic findings in SCD that may associate with a higher risk of surgery, allowing us to make early choices regarding treatment election in this specific group of patients. MATERIALS AND METHODS: This was a retrospective, case-control study. Twenty-four patients diagnosed with SCD between 2013 and 2017 with a past history of stricture-related surgery were included and then matched with 46 non-operated controls. Prior US from patients in both groups were analyzed. US features considered for analysis were as follows: bowel wall thickness, degree of parietal vascularization (measured by Doppler activity), prestenotic dilation, involvement of mesenteric fat, and newly detected concomitant fistulas or abscess. RESULTS: Doppler activity (p < 0.001), enteroenteric fistulas (p = 0.04), enteromesenteric fistulas (p = 0.003), and associated abscess (p = 0.004) were significantly associated with the need for surgery in the short-term period. Multivariate analysis showed strong association of these features with the risk of surgery but failed to reach statistical significance. CONCLUSION: US features may potentially be used as point-of-care tools to aid clinicians in the assessment of the surgical risk in patients with SCD.

INTRODUCTION: the "treat to target" strategy for the management of patients with Crohn's disease (CD) requires simple, reliable and non-invasive tools for continuous monitoring of the disease. Intestinal ultrasound has been proposed as an emerging technique that could be very useful in this field. MATERIAL AND METHODS: patients who had undergone an intestinal ultrasound in the clinical practice between February 2013 and October 2018 at our hospital were retrospectively included. The evolution of the patients during follow-up was assessed based on the presence of ultrasound activity and the therapeutic changes based on the results. RESULTS: two hundred and seventy-seven CD patients were included and the median follow-up time was 24 months (range 5-73 months). Signs of ultrasound inflammatory activity were identified in 166 patients (60 %), and of them, treatment was escalated in 116 patients (70 %) based on the results of the ultrasound. Among patients with identified ultrasound activity, in 166 patients (60 %) the evolution was less favorable than in those without activity, with a shorter time until the next outbreak. Thus, the median disease-free survival (without outbreaks) after performing the ultrasound was 18 months when ultrasound activity was identified (although in most of the patients [70 %] the treatment had been escalated) vs 47 months in patients without ultrasound activity. However, these differences were not statistically significant (p < 0.0001). Among the 111 patients without ultrasound activity, those who achieved "parietal healing" (74 patients) had a better evolution with a 12 % subsequent outbreak vs 27 % during follow-up (p = 0.05). Thus, 15 % of patients with parietal healing had an outbreak vs 34 % of those who had not normalized the ultrasound findings after three years of follow-up. CONCLUSION: intestinal ultrasound is a technique capable of detecting inflammatory activity in patients with Crohn's disease and the presence of ultrasound activity is a risk factor for a new outbreak of activity and/or clinical relapse. Likewise, the presence of "parietal or transmural healing" (PH) is associated with a better evolution of patients during follow-up. Thus, it could be a more precise objective to consider deep remission in CD, with intestinal ultrasound being a useful technique for this purpose.

INTRODUCTION: the Rutgeerts score is used to assess post-surgical recurrence of Crohn's disease (CD). The score initially consisted of four grades, with a subsequent sub-classification of grade 2, under which ulcers confined to the anastomosis (i2a) are considered to be of a probable ischemic origin. The aim of this study was to assess whether ulcers confined to the anastomosis appear at the same frequency in patients undergoing surgery for other causes and can therefore be attributed to post-surgical changes. MATERIAL AND METHODS: this was a retrospective cohort study with patients who had undergone colonoscopy as per clinical practice between 2017 and 2018. There were two cohorts, one cohort of patients to assess the post-surgical recurrence of CD and another cohort for follow-up after colorectal cancer (CRC) treated with ileocolonic anastomosis. RESULTS: a total of 185 patients were included; 33 % had undergone surgery for CD and 67 % had undergone surgery for CRC. Fifty-six percent of patients were male. Of the patients in the group with ulcers confined to the anastomosis, 75 % had CD and 25 % had been operated on for CRC; the difference was statistically significant (p < 0.0001). In turn, of the patients operated on for CRC, 95 % had no anastomotic lesions compared to 18 % of patients with CD. These differences reached statistical significance (p < 0.0001). CONCLUSIONS: In our experience, the occurrence of ulcers on the ileocolonic anastomosis is uncommon in patients that have undergone surgery for CRC, in comparison to patients operated on due to CD. It is possible that these alterations in CD cannot therefore be attributed to solely ischemic or post-surgical phenomena.

INTRODUCTION: The dose of thiopurine drugs in combined treatments with anti-TNF in inflammatory bowel disease (IBD) has not been clearly established. The purpose of this study is to assess whether the dose of azathioprine influences clinical and biochemical response/remission rates, and anti-TNF drug levels/antibody formation. MATERIAL AND METHODS: Patients with IBD on combined maintenance treatment with azathioprine and infliximab or adalimumab were selected. Based on the dose of azathioprine, two groups were defined (standard: 2-2.5mg/kg/day; and decreased: less than 2mg/kg/day). RESULTS: In the IFX group, there were no statistically significant differences (p=0.204) in the rates of remission (39% vs 41.3%), response (10% vs 21.7%) or failure (51.5% vs 37%) depending on the dose of thiopurine drugs. No differences were found between AZA-dose dependent IFX levels (2.46 vs 3.21µg/mL; p=0.211). In the adalimumab group, there were no statistically significant differences (p=0.83) in the rates of remission (66% vs 56%), response without remission (15.38% vs 25%) or failure (18% vs 18%) depending on the dose of thiopurines. With respect to ADA-levels, no differences were found in both groups (7.69 vs 8.23µg/mL; p=0.37). CONCLUSION: In our experience, no statistically significant differences were found in either anti-TNF levels or clinical-biological response/remission rates based on doses of azathioprine.

BACKGROUND: The rates of clinical and biochemical responses in Crohn's disease (CD) patients treated with intravenous (IV) ustekinumab (UST) intensification are scarcely described. METHODS: Patients with diagnosis of CD who were under intensified IV ustekinumab treatment (130 mg every 4 weeks) were retrospectively included, evaluating the clinical and biochemical response 12 weeks after the change in treatment regimen (switch from SC to IV), as well as the serum levels of the drug. RESULTS: Twenty-seven patients, all of whom had transitioned to intensified intravenous ustekinumab treatment due to a secondary loss of response to the drug, were included in the retrospective analysis. At the baseline visit, prior to changing IV UST, differences in levels were observed between intensified and non-intensified patients (7216 vs. 2842 ng/mL, p = 0.00005). However, no significant differences were found between these two groups 12 weeks after IV intensification (7949 vs. 7937 ng/mL; p = 0.99). In patients with previous intensified UST SC, a decrease in fecal calprotectin was observed 12 weeks after starting IV intensification, going from a mean of 1463 ug/g to 751 ug/g, although the differences were not significant (p = 0.14). CONCLUSION: In our experience, intensifying treatment with IV UST leads to clinical and biochemical improvements in CD patients with a secondary loss of response to SC maintenance with this drug, and an increase in drug levels was observed 12 weeks after IV UST intensification.

INTRODUCTION: Intra-abdominal abscesses complicating Crohn's disease (CD) are a challenging situation. Their management, during the hospitalization and after resolution, is still unclear. METHODS: Adult patients with CD complicated with intraabdominal abscess who required hospitalization were included from the prospectively maintained ENEIDA registry from GETECCU. Initial strategy effectiveness and safety to resolve abscess was assessed. Survival analysis was performed to evaluate recurrence risk. Predictive factors associated with resolution were evaluated by multivariate regression and predictive factors associated with recurrence were assessed by Cox regression. RESULTS: 520 patients from 37 Spanish hospitals were included; 322 (63%) were initially treated with antibiotics alone, 128 (26%) with percutaneous drainage, and 54 (17%) with surgical drainage. The size of the abscess was critical to the effectiveness of each treatment. In abscesses < 30mm, the antibiotic was as effective as percutaneous or surgical drainage. However, in larger abscesses, percutaneous or surgical drainage was superior. In abscesses > 50mm, surgery was superior to percutaneous drainage, although it was associated with a higher complication rate. After abscess resolution, luminal resection was associated with a lower 1-year abscess recurrence risk (HR 0.43, 95% CI 0.24-0.76). However, those patients who initiated anti-TNF therapy had a similar recurrence risk whether luminal resection had been performed. CONCLUSIONS: Small abscesses (<30mm) can be managed with antibiotics alone, while larger ones require drainage. Percutaneous drainage will be effective and safer than surgery in many cases. After discharge, anti-TNF therapy reduces abscess recurrence risk in a similar way to bowel resection.
RESUMEN
BACKGROUND: The outbreak of COVID-19 has rapidly evolved into a pandemic that has represented a challenge to health systems worldwide. Inflammatory bowel disease (IBD) units have been forced to change their practices to address the disease and to ensure the quality of care. METHODS: We conducted a national survey among IBD gastroenterologist members of the Spanish Working Group on Crohn's Disease and Colitis regarding changes of practice, IBD treatments, and diagnosis and treatment of COVID-19. RESULTS: We received 54 answers from Spanish hospitals. One hundred percent of the IBD units rescheduled onsite visits to telematic consultation, and elective endoscopic and surgical procedures were delayed. Protective measures were also taken in the infusion units (100% of health centers) and hospital pharmacies, with 40.7% sending subcutaneous medications to patients. No switching between intravenous and subcutaneous anti-tumor necrosis factor drugs were made. We also found that 96.1% of IBD units advised their patients to maintain treatment if they were asymptomatic for COVID-19. For patients with COVID-19 symptoms, 92.6% of IBD units referred them to primary care or the emergency department. In addition, 7.5% of IBD units made a COVID-19 diagnosis through polymerase chain reaction and/or chest x-ray.Modifications in IBD treatment and treatment recommended for COVID-19 are also discussed. CONCLUSIONS: We report a representative national survey of changes made in the structure, diagnosis of COVID-19, and modifications in IBD treatments within IBD units.

Objetivo: La ecografía intestinal se considera una alternativa para la evaluación de la recurrencia posquirúrgica (RPQ) de la enfermedad de Crohn. El objetivo de este estudio es evaluar la correlación entre los hallazgos ecográficos y endoscópicos.Métodos: Se recogieron de forma retrospectiva los datos de pacientes con enfermedad de Crohn y resección ileocecal en los que se había realizado una colonoscopia y una ecografía intestinal para la detección de RPQ. La RPQ se evaluó empleando el índice de Rutgeerts (IR). Los hallazgos ecográficos analizados fueron el grosor de la pared intestinal, la hiperemia parietal por Doppler, la desestructuración del patrón de capas y la proliferación fibrograsa.Resultados: Se incluyó a un total de 31 pacientes, 15 (48,4%) sin recurrencia (IR? mm vs. 5,68mm; p?<0,001). La hiperemia también se asoció de forma significativa con la recurrencia endoscópica (p?=?0,03). Para el grosor parietal se obtuvo un área bajo la curva ROC (AUC) del 92,9% y, con punto de corte en 3,4mm, la sensibilidad fue del 100% y la especificidad del 86,6%. Al comparar con los biomarcadores principales (calprotectina fecal y PCR sérica) se obtuvo un AUC superior para el grosor (72,3% y 72,3% vs. 92,9%).Conclusiones: En nuestra experiencia, la ecografía tiene una alta rentabilidad diagnóstica para la detección de RPQ y puede considerarse en muchas ocasiones como una alternativa válida y no invasiva a la ileocolonoscopia.

Introducción: La dosis adecuada de los fármacos tiopurínicos en tratamientos combinados con anti-TNF en la enfermedad inflamatoria intestinal (EII) no ha sido establecida con claridad. El propósito de este estudio es evaluar si la dosis de azatioprina influye en las tasas de respuesta/remisión clínica y bioquímica y en los niveles de fármaco anti-TNF/formación de anticuerpos. Material y métodos: Se seleccionaron pacientes con EII en tratamiento combinado de mantenimiento con azatioprina (AZA) e infliximab (IFX) o adalimumab (ADA). En función de la dosis de AZA, se definieron dos grupos (estándar: 2-2,5 mg/kg/día o disminuida: menos de 2 mg/kg/día). Resultados: En el grupo IFX no hubo diferencias estadísticamente significativas (p = 0,204) en las tasas de remisión (39 vs. 41,3%), respuesta (10 vs. 21,7%) o fracaso (51,5 vs. 37%), dependiendo de la dosis de fármacos tiopurínicos. No se encontraron diferencias entre los niveles de IFX dependientes de la dosis de AZA (2,46 vs. 3,21 μg/mL; p = 0,211). En el grupo de ADA no hubo diferencias estadísticamente significativas (p = 0,83) en las tasas de remisión (66 vs. 56%), respuesta sin remisión (15,38 vs. 25%) o fallo (18 vs. 18%), dependiendo de la dosis de tiopurinas. Con respecto a los niveles de ADA, no se encontraron diferencias en ambos grupos (7,69 vs. 8,23 μg/mL; p = 0,37). Conclusión: En nuestra experiencia, no se encontraron diferencias estadísticamente significativas ni en los niveles de anti-TNF ni en las tasas de respuesta/remisión clínico-biológica basadas en las dosis de azatioprina.(AU)

Background and aims: response to the SARS-CoV-2 vaccine can be altered in patients with immune-mediated diseases, such as inflammatory bowel disease, and in patients under immunosuppressive treatment. The aims of this study were to evaluate the serologic response to the SARS-CoV-2 vaccine in patients with inflammatory bowel disease, to analyze the influence of immunosuppressive drugs on response, and to describe any adverse events in this population. Methods: this was a prospective study that included adult patients with inflammatory bowel disease. Baseline characteristics, concomitant treatments and previous COVID-19 symptoms were collected. Patients underwent serological testing before the first and after the second vaccine dose. Results: a total of 265 patients were consecutively included. Patients received one of the following vaccines: messenger RNA vaccines from Pfizer/BioNTech and Moderna; and adenovirus vaccines from AstraZeneca and Janssen. All adverse events were mild, and the most frequent was injection site pain in 141 (86 %) patients. The seroconversion rate according to the treatment that patients were receiving was: 100 % for those without treatment, 92.5 % for patients treated with mesalazine, 90.3 % for those receiving immunomodulators, 88.9 % for patients with biological monotherapy and 92.5 % for patients on combined treatment. The generation of antibodies according to the vaccine administered was: Pfizer 92.9 %, Moderna 93.3 %, AstraZeneca 98.4 %, and Janssen 12.5 %. Conclusion: the antibody response after vaccination against SARS-CoV-2 is high in patients with inflammatory bowel disease. However, patients treated with immunosuppressive or biologic drugs had a lower response. Adverse events were frequent, but not serious (AU)
