There is increasing interest in the concept of ‘treat-to-target’ in inflammatory bowel disease as a mechanism to standardize management and prevent complications. While clinical, radiographic and endoscopic treatment end points will figure prominently in this promising management paradigm, the role that noninvasive biomarkers will play is currently undefined. The goal of the present systematic review was to investigate the potential value of biomarkers as treatment targets in inflammatory bowel disease, with particular focus on those best studied: serum C-reactive protein (CRP) and fecal calprotectin. In Crohn disease, elevated CRP levels at baseline predict response to anti-tumour necrosis factor agents, and normalization is usually associated with clinical and endoscopic remission. CRP and hemoglobin levels can be used to help predict clinical relapse in the context of withdrawal of therapy. Ultimately, the authors conclude that currently available biomarkers should not be used as treatment targets in inflammatory bowel disease because they have inadequate operational characteristics to make them safe surrogates for clinical, endoscopic and radiographic evaluation. However, CRP and fecal calprotectin are important adjunctive measures that help alert the clinician to pursue further investigation.

Abstract Background Current noninvasive methods for assessing intestinal inflammation in inflammatory bowel disease (IBD) remain unsatisfactory. Along with C-reactive protein and erythrocyte sedimentation rate, fecal calprotectin (FC) is the standard test for assessing IBD activity, even though its specificity and accuracy are not optimal and it lacks a validated cutoff. Over the past few decades, several fecal markers released from intestinal inflammatory cells have been investigated in IBD; they are the subject of this systematic review. Methods A systematic electronic search of the English literature up to April 2017 was performed using Medline and the Cochrane Library. Only papers written in English that analyzed fecal biomarkers in IBD were included. In vitro studies, animal studies, studies on blood/serum samples, and studies analyzing FC or fecal lactoferrin alone were excluded. Results Out of 1023 citations, 125 eligible studies were identified. Data were grouped according to each fecal marker including S100A12, high-mobility group box 1, neopterin, polymorphonuclear neutrophil elastase, fecal hemoglobin, alpha1-antitrypsin, human neutrophil peptides, neutrophil gelatinase-associated lipocalin, chitinase 3-like-1, matrix metalloproteinase 9, lysozyme, M2-pyruvate kinase, myeloperoxidase, fecal eosinophil proteins, human beta-defensin-2, and beta-glucuronidase. Some of these markers showed a high sensitivity and specificity and correlated with disease activity, response to therapy, and mucosal healing. Furthermore, they showed a potential utility in the prediction of clinical relapse. Conclusions Several fecal biomarkers have the potential to become useful tools complementing FC in IBD diagnosis and monitoring. However, wide variability in their accuracy in assessment of intestinal inflammation suggests the need for further studies.

Abstract The traditional management of inflammatory bowel disease (IBD) based on symptom control is not considered valid anymore by most specialists in this field, and a new paradigm called “treat to target” has been introduced. This is based on the assessment of disease activity using objective measures. The identification of noninvasive biomarkers is crucial to diagnosis and monitor IBD because frequent endoscopic examinations are costly and uncomfortable for the patient. In this review, we focus on blood markers that may be able to assess mucosal healing (MH) in IBD and recent advances in this area. Introduction of commercial panel to predict MH opens the way for further developments so that colonoscopy or fecal markers may be avoided in some patients. This may also permit frequent monitoring for therapeutic response and achieve MH. It is a challenging area of research to identify a panel of biomarkers that may reflect inflammation and healing to serve as a surrogate of MH.

Abstract Background Calgranulin-C (S100A12) is a new faecal marker of inflammation that is potentially more specific for Inflammatory Bowel Disease (IBD) than calprotectin, since it is only released by activated granulocytes. In recent years it has been confirmed that the S100A12 has comparable sensitivity and specificity to fecal calprotectin (FC) in adult patients with IBD. The aim of our study was to evaluate concentration of faecal S100A12 and calprotectin (FC) to see which of the two tests best correlated to inflammation in IBD children. Methods Between September 2019 and March 2020, we prospectively enrolled all IBD pediatric patients, both Crohn’s Disease (CD) and Ulcerative Colitis (UC). Blood and faecal samples were collected in order to evaluate serological markers of inflammation, faecal S100A12A and FC. S100A12 and FC were determined by enzyme-linked immunosorbent assay (ELISA). Results One hundred seventeen consecutive children, 46 (39%) with CD and 71 (61%) with UC were enrolled in the study. The mean age was 14.6 years (range:5–18), 44% female. Twenty three children were in clinical relapse (20%). No significant differences in S100 A12A levels were found between the UC and the CD groups (mean ±ds 25 ±32mcg/ml vs 34 ±27 mcg/ml respectively, p=0.22).In the UC group we found a statistically significant correlation of both calprotectin and S100A12 with CRP (r=0.253, p=0.044 and r=0.252, p=0.040, respectively). In CD group we found that both calprotectin and S100A12 correlated with hemoglobin (r= -0.343, p=0,024; r=-0.401, p 0.008 respectively), hematocrit (r=-0.361, p=0,046; r=-0.434, p=0.015, respectively), fibrinogen (r=0.499, p< 0,001; r=0.325, p =0.038, respectively), and white blood cells count (r=0.309, p=0.044; r=0.394, p=0.021, respectively). Moreover, in CD group, FC correlated with CRP (r=0.431, p=0.004) and erythrocyte sedimentation rate (r=0.430, p=0.004). Finally, S100A12 correlated with platelet count both in CD and UC group (r=0.351, p=0.021and r=0.254, p=0.038, respectively) IBD children in clinical relapse had higher values ​​of S100A12 and FC than patients in remission (66±47 mcg/ml vs 43±42 mcg/ml, p=0.05 and 260±192 mg/Kg vs 166±169 mg/Kg, p=0.046, respectively) Conclusion Our preliminary data show that both faecal S100A12 and FC are useful non-invasive biomarkers which reflect inflammatory activity of IBD children. Our future aim is to evaluate the correlation of S100A12 and endoscopic finding in order to further clarify its role in the diagnosis and the management of pediatric IBD.
