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.

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.

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.
