The New Molecules Are Changing the Course of Pediatric Chronically Active Ulcerative Colitis: A Series of Pediatric Cases.

ABSTRACT: Chronically active ulcerative colitis (UC) constitutes a challenge in an era where medical therapeutic options have increased while experience with colectomies has decreased. The change in the therapeutic paradigm of the disease means that patients with chronically active UC are being managed waiting to find their therapeutic target. We present 2 cases of children with chronically active UC who did not respond to intravenous steroids nor sequential therapy. A response was obtained with ustekinumab and tofacitinib, 2 drugs widely used in adults but still with little evidence in children. Highlighting the important role of patients and their families helped decision-making, facilitating the work of the medical team. With multidisciplinary management and close follow-up, they have been able to avoid surgery entering complete clinical remission.

Project description:Ulcerative colitis (UC) is a complex chronic pathological condition of the gut in which microbiota targeted treatment, such as fecal microbiota transplantation (FMT), has shown an encouraging effect. The aim of the present study was to investigate the efficacy and safety of FMT in patients with mild or moderate UC. A single-center, open-label study was designed, including 47 patients with mild or moderate active UC who received three treatments of fresh FMT via colonic transendoscopic enteral tubing within 1 week. The inflammatory bowel disease questionnaire, partial Mayo scores, colonoscopy, erythrocyte sedimentation rate, C-reactive protein level and procalcitoin values were used to assess the efficacy of FMT and alteration in gut microbiota was detected by 16S ribosomal RNA-sequencing. Before FMT, microbiota Faecalibacterium prausnitzii (F. prausnitzii) levels were significantly decreased in patients with UC compared with healthy donors (P<0.01). At 4 weeks post-FMT, F. prausnitzii levels were significantly increased (P<0.05), and the Mayo score was significantly decreased (1.91±1.07 at baseline vs. 4.02±1.47 at week 4; P<0.001) in patients with UC compared with healthy donors. Steroid-free clinical responses were reported in 37 patients (84.1%), and steroid-free clinical remission was achieved in 31 patients (70.5%) at week 4 post-FMT, however, steroid-free remission was not achieved in any patient. No adverse events were reported in 41 (93.2%) patients after FMT or during the 12-week follow-up. Shannon's diversity index and Chao1 estimator were also improved in patients with UC receiving FMT. In conclusion, the results of the present study suggested that FMT resulted in clinical remission in patients with mild to moderate UC, and that the remission may be associated with significant alterations to the intestinal microbiota of patients with UC. Furthermore, F. prausnitzii may serve as a diagnostic and therapeutic biomarker for the use of FMT in UC.

Project description:BackgroundDue to wide-ranging impacts of Ulcerative Colitis (UC), regulatory authorities emphasize the importance of including validated patient-reported symptom severity measures in clinical trials.AimTo describe the development and validation of the Ulcerative Colitis-Symptom Questionnaire (UC-SQ).MethodsThe UC-SQ was developed in a qualitative study involving a targeted literature review, semi-structured concept elicitation interviews, and combined concept elicitation/cognitive interviews. Measurement properties, including item-level analyses, factor structure, reliability, validity, responsiveness, and clinically meaningful change were evaluated using data from a phase 2b, randomized trial in adults with UC (N = 113).ResultsFourteen symptom concepts were elicited across 22 interviews, with saturation at the fifth interview. Twenty-two items were unmodified as cognitive interview participants interpreted underlying concepts correctly. Instructions were clear and items were relevant, with appropriate response options and recall periods. Reduction to 17 items was completed prior to psychometric testing. Two items (joint pain/constipation) did not contribute to reliability in initial testing and were included as non-scored items. The 15-item UC-SQ showed evidence of internal consistency (α = 0.86) and test-retest reliability (intraclass correlation coefficient = 0.88). The UC-SQ discriminated by disease severity as defined by Mayo and Inflammatory Bowel Disease Questionnaire scores (p < 0.0001). Convergent validity was supported by strong correlations with criterion measures. The UC-SQ was responsive in patients indicating change in other measures. A 10-point decrease from baseline indicated within-patient meaningful improvement.ConclusionsThe UC-SQ is reliable, valid and responsive, with a 10-point improvement estimating within-patient clinically meaningful improvement. The tool is fit-for-purpose as a key endpoint in pivotal UC trials.
