There is an increasing interest in non-invasive methods to assess gut inflammation. The data regarding the correlations between inflammatory markers and activity of inflammatory bowel disease (IBD) are still controversial. In the last years faecal calprotectin became the most widely used biomarker in diagnosis and monitoring the IBD activity. We prospectively studied the correlation between the serological inflammatory markers (platelets, erythrocyte sedimentation rate - ESR, fibrinogen, C Reactive Protein -CRP, ferritin, albumin), faecal calprotectin and severity of IBD in a tertiary referral centre in North-East Romania. Our study demonstrated that is a good correlation between serologic inflammatory markers (platelets, fibrinogen and ferritin, not ESR and albumin) and severity of IBD. CRP is a good marker in Crohn�s disease (CD) but not in ulcerative colitis (UC). Faecal calprotectin (FC) is the best inflammatory biomarker which correlates with activity both in UC and CD. Inflammatory biomarkers, especially FC are an important tool to evaluate patients with IBD.

Abstract Background and Aims Faecal calprotectin [FC] is a valid and non-invasive marker of mucosal inflammation. It is widely used both in clinical trials and in daily clinical practice for patients with inflammatory bowel diseases, but currently no accepted standardization for FC testing is available. Our primary aim here was to provide a clinician’s guide containing all the practical information on FC measurement in order to avoid any confounding factors, to minimize intra- and inter-individual variability in dosage, and to ensure a better and adequate interpretation of the results. Methods We conducted a detailed search of the scientific literature in the PubMed/MEDLINE, EMBASE and Cochrane databases up to January 2020 to find all relevant and available articles on pre-analytical and analytical phases of FC measurement. Results FC testing is a multi-step procedure consisting of a pre-analytical phase aimed to collect and process the stool sample and a subsequent analytical phase of FC measurement. Several factors can influence test results determining false positives or false negatives. Importantly, this faecal marker is mostly used for patient follow-up and as a predictor of treatment response. For this reason, any altered data may affect the physicians’ decisions, negatively impacting on patient management. Conclusions This review provides for the first time practical advice to minimize dosage variability, although further dedicated studies are needed to compare commercially available tests and identify the best tools for the most precise and accurate FC measurement.

AbstractPatients with inflammatory bowel disease (IBD) report fatigue more frequently than healthy population, but the precise mechanisms underlying its presence are unknown. This study aimed to evaluate the prevalence of fatigue in IBD and its relation with potential causative factors. A survey on fatigue, depression, anxiety, sleep disorders, and the presence of sarcopenia and malnutrition, was sent by email to 244 IBD outpatients of the Gastroenterology Unit of Academic Hospital of Padua. Demographics and clinical data, including the levels of fecal calprotectin (FC) and C-reactive protein (CRP), and current pharmacological treatments were obtained from patients’ medical records. Ninety-nine (40.5%) subjects answered the survey. Ninety-two (92.9%) patients reported fatigue, with sixty-six having mild to moderate fatigue and twenty-six severe fatigue. Multivariate analysis showed that abnormal values of CRP (OR 5.1), severe anxiety (OR 3.7) and sarcopenia (OR 4.4) were the factors independently associated with severe fatigue. Fatigue has a high prevalence in subject affected by IBD. Subjects with altered CRP, sarcopenia and severe anxiety appear more at risk of severe fatigue.

Abstract Background Inflammatory bowel diseases (IBD) are characterized by an increased thrombosis risk of uncertain etiology. Coagulation derangement arising from inflammation may be a triggering factor. We hypothesized that strong inflammation inhibitors (eg, anti-tumor necrosis factor-α drugs) may affect coagulation. Methods Forty patients with IBD were compared with 57 control patients for coagulation factors and endogenous thrombin potential (ETP), the latter being the most sensitive marker of in vivo pro- and anticoagulation balance. We measured ETP in the presence and absence of thrombomodulin (the physiologic protein C [PC] activator). Coagulation at different timepoints was also assessed for 28 of these patients during infliximab treatment. Results The median ETP (nM thrombin × minutes) and range (minimum-maximum) were each higher in patients at baseline than in control patients in both the absence (2120 [1611-3041] vs 1865 [1270-2337]) and the presence (1453 [464-2522] vs 831 [104-1741]) of thrombomodulin. The ETP ratio (with/without thrombomodulin) was high at baseline (0.73 [0.21-0.90] vs 0.45 [0.07-0.85]). The ETP and ETP ratio declined during treatment and were significantly lower at the end than at baseline. Factor (F) VIII and fibrinogen, which were high at baseline, decreased during treatment and at the end were significantly lower than at baseline. The FVIII/PC ratio, which was high in patients at baseline, declined during treatment and at the end was lower than at baseline. C-reactive protein recorded at the end of treatment was lower than at baseline. Conclusions Patients with IBD have a procoagulant imbalance as shown by increased ETP at baseline. The ETP decreases during treatment with infliximab, which is related to decreased FVIII and FVIII/PC ratio. This effect is also related to the improvement of inflammation as shown by decreased fibrinogen and C-reactive protein.

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.

Objectives. The aims of this study were to evaluate the C-reactive protein/albumin ratio (CRP/ALB), inflammatory markers, and parameters from the complete blood count (CBC) in patients with inflammatory bowel disease (IBD) and their associations with disease activity. Methods. A total of 876 IBD patients, composed of 275 patients with ulcerative colitis (UC) and 601 patients with Crohn’s disease (CD), were included in this retrospective study, and the serum C-reactive protein (CRP), albumin (ALB), erythrocyte sedimentation rate (ESR), and CBC parameters were measured. To explore the disease activity, the Mayo score and Crohn disease activity index were used to assess UC and CD patients, respectively. Results. The CRP/ALB ratio, CRP, ESR, platelet to lymphocyte ratio (PLR), red blood cell distribution width (RDW), and neutrophil to lymphocyte ratio (NLR) levels in active IBD patients were significantly higher than those in inactive IBD patients, whereas ALB and lymphocyte to monocyte ratio (LMR) levels were significantly decreased (P<0.001). The receiver operating characteristic analysis showed that the optimum cut-off values of the CRP/ALB ratio for active UC and CD were 0.18 and 0.43, with sensitivities of 67.8% and 75.8% and specificities of 86.7% and 92.0%, respectively. Multivariable logistic analysis revealed that after adjusting for these inflammatory markers (ESR, NLR, PLR, and LMR), the CRP/ALB ratio was a statistically significant parameter capable of differentiating the disease activity of UC and CD. Conclusions. This study indicated that the CRP/ALB ratio was closely related to the IBD disease activity. Compared with CBC parameters, the CRP/ALB ratio had a higher discriminative capacity for active IBD.

Abstract Background Biologic therapy has demonstrated efficacy for induction and maintenance of remission in ulcerative colitis (UC). However, it remains unclear whether oral aminosalicylates (5-ASA) should be continued or stopped after treatment escalation to biologics. The aim of the study was to evaluate differences in inflammatory biomarkers or the occurrence of complications in UC patients being treated with a combination of 5-ASA and biologics vs. biologics alone. Methods Retrospective study, including patients with UC and on biologic therapy with a minimum follow-up of 6 months. Collected inflammatory biomarkers were faecal calprotectin, C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR). The occurrence of complications was defined as the need of hospitalisation, need of corticosteroids or other top-up therapy, surgery and the occurrence of dysplasia or colorectal cancer. Results We included 65 patients with UC, 56.9% female with a mean age of 32.8 (±12.8) years. The median follow-up was 30 (6–132) months. Regarding extension, 61.5% were E3, 35.4% E2 and 3.1% E1. While 44 patients (67.7%) were on 5-ASA and biologics (infliximab = 32, adalimumab = 6, vedolizumab = 6), 21 (32.3%) were on biologics alone (infliximab = 13, adalimumab = 3, vedolizumab = 5). The median duration of biologic therapy was 30 (6–126) months. Regarding baseline characteristics, including age, gender, duration of the disease or biologic therapy and age at UC diagnosis, there were no differences between groups. No differences regarding inflammatory biomarkers were observed – fecal calprotectin (p = 0.39), CRP (p = 0.9) and ESR (p = 0.61). No differences were found regarding complications, namely the need of hospitalisation (p = 0.06) or need of corticosteroids (p = 0.89). Only one patient developed dysplasia (under infliximab and 5-ASA). Any of the included patients needed surgery or developed colorectal cancer. Conclusion About two-thirds of the UC patients under biologics are co-treated with 5-ASA. No differences between UC patients under combination biologics+5-ASA vs. biologics alone were found regarding inflammatory biomarkers or the occurrence of complications. These results raise the question if continuing 5-ASA in UC patients under biologics is really necessary.

Vedolizumab, a monoclonal antibody directed against integrin α4β7, is an effective treatment for inflammatory bowel diseases. However, a significant number of patients do not achieve steroid-free clinical remission in the first year of treatment. An early identification of these patients is one of the most important challenges for clinicians and offers the possibility of therapeutic optimization in order to personalize biological therapy. The aim of our study was to test the prediction ability of interleukin (IL)-6 and -8 of clinical response after 12 months of therapy with vedolizumab (T2). We performed a prospective, multicentre study in patients affected by inflammatory bowel disease by analysing cytokines level before starting vedolizumab (T0) and after 10 weeks of therapy (T1). In the overall cohort (n = 54), IL-8 decrease > 2.6 pg/mL in the first 10 weeks of therapy was able to predict clinical response (area under the curve (AUC) = 0.70, sensitivity = 66%, specificity = 75%, p = 0.010), negative C-reactive protein (CRP) (AUC = 0.71, sensitivity = 64%, specificity = 80%, p = 0.009) and calprotectin < 250 mg/kg (AUC = 0.69, sensitivity = 64%, specificity = 78%, p = 0.030) after 44 weeks of therapy. In patients with ulcerative colitis (n = 40), baseline IL-8 values > 8.6 pg/mL and a decrease of IL-6 values > 0.4 pg/mL from T0 to T1 were significant and independent predictors of clinical response after 12 months of vedolizumab therapy (odds ratio (OR) = 6.96, 95% CI 1.27–38.22, p = 0.026 and OR = 7.29, 95% CI 1.42–37.50, p = 0.017, respectively). In patients with Crohn’s disease (n = 14), baseline IL-8 values > 8.6 pg/mL and baseline IL-6 values > 1.6 pg/mL allowed the identification of patients achieving negative CRP at T2 (AUC = 0.75, sensitivity = 74%, specificity = 76%, p < 0.001) and patients with faecal calprotectin values < 250 mg/kg at T2 (AUC = 0.71, sensitivity = 78%, specificity = 63%, p = 0.004). In conclusion, our study highlights a potential clinical role of serum cytokine levels for the prediction of clinical and biochemical steroid-free response in patients treated with vedolizumab.

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 The availability of subcutaneous (SC) administration devices of biologics in addition to intravenous (IV) administration has influenced patients’ and clinicians’ preferences towards initiating or transitioning to SC administration particularly during the COVID-19 pandemic. Whilst SC administration improves patient convenience and reduces demands on infusion centres we hypothesised that the reduction in healthcare contact associated with SC therapies may reduce the opportunities available for objective disease assessment. We aimed to compare the uptake of objective assessment of disease activity between patients receiving IV and SC biologic therapy. Methods Patients on maintenance infusion-based or subcutaneous biologic therapy for IBD between 09/2020 and 02/2021 were identified from a prospectively maintained database at an Australian tertiary IBD centre. Patients scheduled for review in IBD clinic for a prescription of maintenance biologic therapy during the follow-up period were included. Clinic records were reviewed to determine whether patients had undergone objective disease assessment including: biochemical investigation (C-Reactive protein) and Faecal Calprotectin (FCP) within the preceding 8 weeks and/or endoscopic/imaging assessment within the preceding 6 months of clinic review. Frequency of objective disease assessment was compared between patients who received IV versus SC maintenance biologic therapy. Results A total of 307 patients were included: IV maintenance n=195 (Infliximab n=135; Vedolizumab n= 60) and SC maintenance n=112 (Adalimumab n=54; Ustekinumab n=54; Golimumab n=4). Patients who received IV biologics were more likely than the SC cohort to have had biochemical assessment in the form of CRP (90% vs 72%, p&lt;0.001) and FCP (54% vs 46%, p=0.16). Patients in the SC biologic cohort were more likely not to have had investigations completed prior to their clinical review (20% versus 4%, p&lt;0.001). There was no difference in the overall rates of complete objective disease assessment (CRP/FCP and endoscopy/imaging) between the IV and SC cohort (28% vs 30% (p=0.74). Conclusion Patients on subcutaneous biologic therapies in our cohort were less likely to have had objective disease monitoring than those receiving intravenous biologics prior to scheduled IBD clinic review. Route of of biologic administration may influence rates of uptake of objective disease activity assessment. Tools that safeguard against the disparity of monitoring uptake, including messaging prompts and patient-centric mobile applications may help standardise the approach to objective disease assessment independent of the route of biologic administration.
