Early diagnosis of inflammatory bowel disease (IBD), including Crohn’s disease (CD) and ulcerative colitis (UC), remains a clinical challenge with current tests being invasive and costly. The analysis of volatile organic compounds (VOCs) in exhaled breath and biomarkers in stool (faecal calprotectin (FCP)) show increasing potential as non-invasive diagnostic tools. The aim of this pilot study is to evaluate the efficacy of breath analysis and determine if FCP can be used as an additional non-invasive parameter to supplement breath results, for the diagnosis of IBD. Thirty-nine subjects were recruited (14 CD, 16 UC, 9 controls). Breath samples were analysed using an in-house built electronic nose (Wolf eNose) and commercial gas chromatograph–ion mobility spectrometer (G.A.S. BreathSpec GC-IMS). Both technologies could consistently separate IBD and controls [AUC ± 95%, sensitivity, specificity], eNose: [0.81, 0.67, 0.89]; GC-IMS: [0.93, 0.87, 0.89]. Furthermore, we could separate CD from UC, eNose: [0.88, 0.71, 0.88]; GC-IMS: [0.71, 0.86, 0.62]. Including FCP did not improve distinction between CD vs UC; eNose: [0.74, 1.00, 0.56], but rather, improved separation of CD vs controls and UC vs controls; eNose: [0.77, 0.55, 1.00] and [0.72, 0.89, 0.67] without FCP, [0.81, 0.73, 0.78] and [0.90, 1.00, 0.78] with FCP, respectively. These results confirm the utility of breath analysis to distinguish between IBD-related diagnostic groups. FCP does not add significant diagnostic value to breath analysis within this study.

Abstract Background ECCO guidelines state that patients started on biologic therapy for Inflammatory Bowel Disease (IBD) should be reviewed between week 10 and 16 depending on the biologic used and response assessed using predefined objective criteria. The study aim was to ascertain, the time point, and by which methods patients with IBD are being assessed for primary response. Methods A retrospective chart review was conducted of 50 consecutive patients with IBD who had been started on biological therapy between October 2018 and June 2019 at a tertiary referral university teaching hospital in London, UK. Results Patients were started on 5 biologics; infliximab (20 patients), adalimumab (11 patients), vedolizumab (6 patients), ustekinumab (9 patients) and tofacitinib (4 patients). Twenty two patients had Ulcerative Colitis and 28 patients had Crohn’s Disease. All 50 patients were still receiving biological therapy at the time of their first assessment in a consultant led IBD clinic. On average, patients were assessed at week 13 for primary response. Figure 1 outlines the time to assessment of disease response, according to the biologic used. The most frequently used methods were clinical symptoms (49 patients, 98%) and blood tests (47 patients, 94%). Disease activity scores were rarely documented. Other methods of disease assessment were faecal calprotectin (13 patients, 26%), ileocolonoscopy (11 patients, 22%) and radiological studies (2 patients, 4%). Only 19 patients (38%) had either a faecal calprotectin or a colonoscopy ordered at their appointment. Thirteen patients (26%) had undergone an endoscopic assessment of their disease when the data was analysed in December 2019. Conclusion Patients are being assessed in a timely fashion for primary response to biological therapy, in line with current ECCO guidelines. Clinical symptoms and blood tests are being heavily relied on to assess for primary response to therapy. Patient-reported symptoms do not correlate well with mucosal inflammation in IBD1. Faecal Calprotectin, as a surrogate marker of mucosal inflammation, and colonoscopy are being underused. Potential reasons for the low rates of colonoscopy may include patient’s wishes and lack of endoscopy capacity. The importance of a mucosal healing assessment is imperative to be able to optimise treatment appropriately and improve long-term outcomes for our patients. Reference

Crohn's disease and ulcerative colitis are chronic inflammatory disorders affecting the gastrointestinal tract. Faecal calprotectin is a protein complex of the S-100 family of calcium-binding proteins present in inflammatory cells that can be measured in stool samples, which act as a biomarker for bowel inflammation. Elevated faecal calprotectin has been shown to reflect the presence of ongoing mucosal inflammation, which improves with mucosal healing. The aim of this review was to evaluate the available evidence on the ability of faecal calprotectin to predict a relapse in inflammatory bowel disease. Multiple retrospective studies have shown that patients who relapse have significantly higher levels of calprotectin in their stool compared with non-relapsers, especially in ulcerative colitis. Elevated faecal calprotectin postoperatively in Crohn's disease was also shown to be indicative of a relapse. However, the association of a raised faecal calprotectin and relapse is not universal and may be explained by the different patterns of mucosal inflammatory activity that exist. In conclusion, we put forward our hypothesis that changes such as a rise in faecal calprotectin levels may be more predictive of a relapse than absolute values.

Background Faecal calprotectin has been widely used as a non-invasive marker of intestinal inflammation in children. Measurement of faecal haemoglobin using faecal immunochemical test is well established in adults for detection of colorectal cancer. In adults, faecal haemoglobin has been recommended as a reliable tool to aid identification of those at low risk of significant bowel disease and has also been used in inflammatory bowel disease to assess mucosal healing. Aims We aimed to evaluate the performance of faecal haemoglobin in the paediatric population and compare it with faecal calprotectin. Methods Children being assessed in the paediatric gastroenterology clinic for bowel symptoms had a sample sent for both faecal calprotectin and faecal haemoglobin. Samples were collected over a 10-month period from November 2018 to September 2019. Faecal haemoglobin was measured using an OC-Sensor. Faecal calprotectin was measured using Liason®Calprotectin. Results One hundred forty three samples were returned for faecal haemoglobin and in 107 a paired faecal calprotectin was also available. Faecal haemoglobin correlated with faecal calprotectin, Spearman’s rank coefficient 0.656 ( P < 0.0001). There were 35 patients with faecal haemoglobin >20 μg/g and in 32 of these patients faecal calprotectin was >200 μg/g; 74 patients with faecal haemoglobin and 38 patients with faecal calprotectin underwent colonoscopy. Patients with normal histology had faecal haemoglobin <4 μg/g; faecal haemoglobin >20 µg/g was associated with signification inflammation Conclusion Our study is the first to compare faecal haemoglobin and faecal calprotectin in a paediatric population. Results suggest that faecal haemoglobin correlates with faecal calprotectin and, as in adults, may be useful to rule out significant bowel disease. A faecal haemoglobin >20 μg/g was consistent with significant histological inflammation.

The Impact

The assessment and management of patients with known, or suspected, paediatric inflammatory bowel disease (PIBD) has been hugely impacted by the COVID-19 pandemic. Although current evidence of the impact of COVID-19 infection in children with PIBD has provided a degree of reassurance, there continues to be the potential for significant secondary harm caused by the changes to normal working practices and reorganisation of services.Disruption to the normal running of diagnostic and assessment procedures, such as endoscopy, has resulted in the potential for secondary harm to patients including delayed diagnosis and delay in treatment. Difficult management decisions have been made in order to minimise COVID-19 risk for this patient group while avoiding harm. Initiating and continuing immunosuppressive and biological therapies in the absence of normal surveillance and diagnostic procedures have posed many challenges.Despite this, changes to working practices, including virtual clinic appointments, home faecal calprotectin testing kits and continued intensive support from clinical nurse specialists and other members of the multidisciplinary team, have resulted in patients still receiving a high standard of care, with those who require face-to-face intervention being highlighted.These changes have the potential to revolutionise the way in which patients receive routine care in the future, with the inclusion of telemedicine increasingly attractive for stable patients. There is also the need to use lessons learnt from this pandemic to plan for a possible second wave, or future pandemics as well as implementing some permanent changes to normal working practices.In this review, we describe the diagnosis, management and direct impact of COVID-19 in paediatric patients with IBD. We summarise the guidance and describe the implemented changes, evolving evidence and the implications of this virus on paediatric patients with IBD and working practices.

Introduction: Fecal calprotectin (FC) is a useful non-invasive screening test but elevated levels are not specific to inflammatory bowel disease (IBD). The study aimed to evaluate the sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) of FC alone or FC in combination with other standard blood tests in the diagnosis of IBD.Methods: Children aged &lt;17 years who had FC (normal range &lt;50 μg/g) measured and underwent endoscopy over 33 months in Christchurch, New Zealand were identified retrospectively (consecutive sampling). Medical records were reviewed for patient final diagnoses.Results: One hundred and two children were included; mean age was 12.3 years and 53 were male. Fifty-eight (57%) of the 102 children were diagnosed with IBD: 49 with Crohn's disease, eight with ulcerative colitis and one with IBD-unclassified. FC of 50 μg/g threshold provided a sensitivity of 96.6% [95% confident interval (CI) 88.3–99.4%] and PPV of 72.7% (95% CI 61.9–81.4%) in diagnosing IBD. Two children with IBD however were found to have FC &lt;50 μg/g. Sensitivity in diagnosing IBD was further improved to 98.3% (95% CI 90.7–99.1%) when including FC &gt;50 μg/g or elevated platelet count. Furthermore, PPVs in diagnosing IBD improved when FC at various thresholds was combined with either low albumin or high platelet count.Conclusion: Although FC alone is a useful screening test for IBD, a normal FC alone does not exclude IBD. Extending FC to include albumin or platelet count may improve sensitivity, specificity, PPV and NPV in diagnosing IBD. However, prospective studies are required to validate this conclusion.
