Resumen Objetivo La ecografia intestinal se considera una alternativa para la evaluacion de la recurrencia posquirurgica (RPQ) de la enfermedad de Crohn. El objetivo de este estudio es evaluar la correlacion entre los hallazgos ecograficos y endoscopicos. Metodos Se recogieron de forma retrospectiva los datos de pacientes con enfermedad de Crohn y reseccion ileocecal en los que se habia realizado una colonoscopia y una ecografia intestinal para la deteccion de RPQ. La RPQ se evaluo empleando el indice de Rutgeerts (IR). Los hallazgos ecograficos analizados fueron el grosor de la pared intestinal, la hiperemia parietal por Doppler, la desestructuracion del patron de capas y la proliferacion fibrograsa. Resultados Se incluyo a un total de 31 pacientes, 15 (48,4%) sin recurrencia (IR? Conclusiones En nuestra experiencia, la ecografia tiene una alta rentabilidad diagnostica para la deteccion de RPQ y puede considerarse en muchas ocasiones como una alternativa valida y no invasiva a la ileocolonoscopia.

Data regarding bowel preparation in patients with Inflammatory Bowel Disease (IBD) are scarce.To compare efficacy, safety, and tolerability of low-volume preparations in patients with IBD.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 assessedNinety-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 (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.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.

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: 2–2.5 mg/kg/day; and decreased: less than 2 mg/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 3.21 μg/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 8.23 μg/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: Bowel preparation is crucial for colonoscopies in patients with Inflammatory Bowel Disease (IBD). However, data regarding cleansing solutions in this setting are scarce. AIMS: Our aim was to compare efficacy, safety, and tolerability of three different 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). Primary endpoint was efficacy in terms of percentage of quality cleansing assessed via the Boston Bowel Preparation Scale (BBPS >=6 with segments >=2). Secondary endpoints were efficacy in terms of total high quality cleansing (BBPS 8 or 9), high quality segmental BBPS (>=2) and patients’ tolerability, symptoms, and satisfaction, assessed by questionnaires before and after colonoscopy. Safety was monitored by adverse event reporting, laboratory evaluation at colonoscopy and telephonic follow-up.RESULTS: 92 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). Clinically irrelevant hyponatremia was higher in the SP group (pCONCLUSIONS: We observed no differences between PEG-based bowel preparations and SP regarding efficacy 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.

Chronic immune-mediated diseases, including inflammatory bowel disease (IBD), present an increased risk of developing early atherosclerosis and cardiovascular events (CVE) at early age.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.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.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).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.

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.

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.

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.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.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 (p0.0001). 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.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.
