Abstract
Patients with pediatric inflammatory bowel disease (pIBD) are at an increased risk for complications and comorbidities including infection, nutritional deficiencies, growth delay, bone disease, eye disease, malignancy, and psychologic disorders. Preventative health maintenance and monitoring is an important part to caring for patients with pIBD. Although practice is variable and published study within pIBD is limited, this article summarizes the important field of health-care maintenance in pIBD. A multidisciplinary approach, including the gastroenterologist provider, primary care provider, social worker, psychologist, as well as other subspecialists is necessary.

Diverticular Inflammation and Complication Assessment classification, CODA score and fecal calprotectin in clinical assessment of patients with diverticular disease: A decision curve analysis. United European Gastroenterol J 2023; 11:642-653. [PMID: 37550901 PMCID: PMC10493361 DOI: 10.1002/ueg2.12369] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/12/2022] [Accepted: 01/29/2023] [Indexed: 08/09/2023] Open
Abstract
BACKGROUND AND AIMS The Diverticular Inflammation and Complication Assessment (DICA) classification and the Combined Overview on Diverticular Assessment (CODA) were found to be effective in predicting the outcomes of Diverticular Disease (DD). We ascertain whether fecal calprotectin (FC) can further aid in improving risk stratification. METHODS A three-year international, multicentre, prospective cohort study was conducted involving 43 Gastroenterology and Endoscopy centres. Survival methods for censored observations were used to estimate the risk of acute diverticulitis (AD) in newly diagnosed DD patients according to basal FC, DICA, and CODA. The net benefit of management strategies based on DICA, CODA and FC in addition to CODA was assessed with decision curve analysis, which incorporates the harms and benefits of using a prognostic model for clinical decisions. RESULTS At the first diagnosis of diverticulosis/DD, 871 participants underwent FC measurement. FC was associated with the risk of AD at 3 years (HR per each base 10 logarithm increase: 3.29; 95% confidence interval, 2.13-5.10) and showed moderate discrimination (c-statistic: 0.685; 0.614-0.756). DICA and CODA were more accurate predictors of AD than FC. However, FC showed high discrimination capacity to predict AD at 3 months, which was not maintained at longer follow-up times. The decision curve analysis comparing the combination of FC and CODA with CODA alone did not clearly indicate a larger net benefit of one strategy over the other. CONCLUSIONS FC measurement could be used as a complementary tool to assess the immediate risk of AD. In all other cases, treatment strategies based on the CODA score alone should be recommended.

[PMID: 37512053 PMCID: PMC10383955 DOI: 10.3390/medicina59071240] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/31/2023] [Revised: 06/22/2023] [Accepted: 06/28/2023] [Indexed: 07/30/2023]
Abstract
Background and Objectives: Calprotectin is a marker for intestinal inflammation. Recent research suggests a link between inflammation and depression. This study assessed the association between the levels of calprotectin in patients from South-Eastern Europe and the severity of depression, anxiety, and quality of life. Materials and Methods: This cross-sectional study included 30 confirmed patients with Crohn's disease (CD) and ulcerative colitis (UC) who were assessed using clinical interviews for determining the severities of mental disorders (i.e., depression severity-PHQ-9, anxiety-GAD-7) and the quality of life (EQ-5D). Stool samples were collected from all participants for measuring their levels of calprotectin. Results: The level of calprotectin is correlated with PHQ-9 (ρ = 0.416, p = 0.022) and EQ-5D (ρ = -0.304, p = 0.033) but not with GAD 7 (ρ = 0.059, p = 0.379). Calprotectin levels in patients with mild, moderate, and moderately severe depression were significantly higher than in patients with minimal depression (198 µg/g vs. 66,9 µg/g, p = 0.04). Calprotectin level was corelated with the following depressive symptoms: autolytic ideation (ρ = 0.557, p = 0.001), fatigue (ρ = 0.514, p = 0.002), slow movement (ρ = 0.490, p = 0.003), and sleep disorders (ρ = 0.403, p = 0.014). Calprotectin was an independent predictor of depression with an odds ratio of 1.01 (95%: 1.002-1.03, p < 0.01). An ROC analysis showed that a level of calprotectin of 131 µg/g or higher has a sensitivity of 82%, a specificity of 61%, and an accuracy of 70% for predicting depression. In this study, no significant correlations were found between calprotectin level and anxiety. Conclusions: Calprotectin levels are associated with the severity of depression, and checking for a calprotectin level of 131 µg/g or higher may be a potential accessible screening test for depression in patients with inflammatory bowel disease.

Abstract
Background Ulcerative colitis (UC), a chronic inflammatory disease of gastrointestinal tract, can have initial presentation which is clinically difficult to differentiate from functional bowel disorders [irritable bowel syndrome (IBS) and irritable bowel disease (IBD)]. Conventional laboratory tests, such as erythrocyte sedimentation rate (ESR), C-reactive protein, and albumin express systemic patient responses instead of intestinal inflammation. In the last decade, fecal calprotectin, a calcium-binding protein, has been suggested as a sensitive marker of intestinal inflammation. However, only few studies have investigated its role in relation with the extent of the disease. Aim To evaluate the usefulness of fecal calprotectin as a biomarker for disease activity in UC, its correlation with disease extent and its utility in differentiating IBS from IBD. Methods A total of 75 patients (50 cases with colonoscopic evidence of inflammation and 25 cases with normal colonoscopic examination) were included in the study. Fecal calprotectin test was done on the day of colonoscopy. Severity of the disease was assessed by modified Mayo's endoscopy score (MMES). Results Age and baseline parameters were comparable in both the groups (UC and IBS). Patients in the ulcerative group had tachycardia (95 vs 74), high ESR (26 vs 20), high leukocytes count (9198 vs 8852), high fecal calprotectin (594 vs 29), low albumin (3.00 vs 3.80) and low hemoglobin (11 vs 13.40). Minimum and maximum MMES were 2 and 13.2. A significant correlation was observed between fecal calprotectin and MMES (p-value < 0.001). Conclusion Fecal calprotectin is a simple, noninvasive, cost-effective marker that is strongly associated with colorectal inflammation; moreover, it has better role in the differentiation of IBD (UC) from IBS.

Abstract
Alterations to the intestinal barrier may be involved in the pathogenesis of various chronic diseases. The diagnosis of mucosal barrier disruption has become a new therapeutic target for disease prevention. The aim of this study was to determine whether various patient demographic and biometric data, often not included in diagnostic analyses, may affect calprotectin, zonulin, and sIgA biomarker values. Stool markers' levels in 160 samples were measured colorimetrically. The analysis of twenty key bacteria (15 genera and 5 species) was carried out on the basis of diagnostic tests, including cultures and molecular tests. The concentrations of selected markers were within reference ranges for most patients. The sIgA level was significantly lower in participants declaring probiotics supplementation (p = 0.0464). We did not observe differences in gastrointestinal discomfort in participants. We found significant differences in the sIgA level between the 29-55 years and >55 years age-related intervals groups (p = 0.0191), together with a significant decreasing trend (p = 0.0337) in age-dependent sIgA concentration. We observed complex interdependencies and relationships between their microbiota and the analyzed biomarkers. For correct clinical application, standardized values of calprotectin and sIgA should be determined, especially in elderly patients. We observed a correlation between the composition of the gut community and biomarker levels, although it requires further in-depth analysis.

Abstract
Pediatric Crohn's disease is often more severe, requires higher levels of immunosuppression, and is associated with greater morbidity compared with adult Crohn's disease. Unique considerations in pediatric Crohn's disease include growth impairment, pubertal delay, bone disease, longevity of disease burden, and psychosocial impact. Treatment options are limited, requiring off-label use of therapy in this challenging patient population. Understanding the medications available, the existing evidence supporting their use, and side effects is important. There is tremendous potential for growth and improvement in this field and it is essential that all gastroenterologists have an understanding of this complex and unique patient population.

Abstract
Leaky gut hypothesis is one of the well-known theory which tries to explain etiology of Autism Spectrum Disorder (ASD). Unfortunately there is still a gap of evidence to investigate the corner points of the hypothesis. The aim of this study was to investigate the determinants of leaky gut in children with ASD, their siblings and healthy controls. Intestinal microbiota was found to be similar between ASD and sibling groups. Biological markers of bacterial translocation showed a significant difference in the sibling group, whereas the marker indicating local inflammation was not different between the groups. The findings from this study did not support the role of Gut microbiota or leaky gut on the etiology of autism.

Abstract
Introduction The presence of inflammation is a key hallmark of cancer and, plays an important role in disease progression and survival in colorectal cancer (CRC). Calprotectin detected in the faeces is a sensitive measure of colonic inflammation. The role of FC as a diagnostic test that may categorise patients by risk of neoplasia is poorly defined. This systematic review and meta-analysis aims to characterise the relationship between elevations of FC and colorectal neoplasia. Methods A systematic review was performed using the keywords (MESH terms) and a statistical and meta-analysis was performed. Results A total of 35 studies are included in this review. CRC patients are more likely than controls to have an elevated FC OR 5.19, 95% CI 3.12–8.62, p < 0.001 with a heterogeneity (I2 = 27%). No tumour characteristics significantly correlated with FC, only stage of CRC shows signs that it may potentially correlate with FC. Conclusion FC levels are significantly higher in CRC, with high sensitivity. Its low specificity prevents it from being used to diagnose or screen for CRC.

Abstract
Background and Aims Fecal calprotectin (FC) is a noninvasive biomarker used in inflammatory bowel disease (IBD) management and risk stratification of nonspecific gastrointestinal symptoms. Leukocyte esterase is an inexpensive and widely available point-of-care inflammatory marker present on urinalysis test strips. We aim to assess the diagnostic accuracy of fecal leukocyte esterase (FLE) relative to FC and endoscopy and demonstrate its use as an alternative biomarker for IBD. Methods In this prospective cohort study, 70 patients who had FC ordered as part of standard clinical care also received FLE testing. FLE levels were compared with various FC cutoff values and endoscopy and pathology findings as the gold standard. Results As the FC cutoff increased from 50 to 500 μg/g, FLE sensitivity increased from 67% to 95% while the specificity decreased from 86% to 76%. The area under the receiver operating characteristic (AUROC) curve increased from 0.79 to 0.90. An FLE of ≥1+ had the best test characteristics. Among patients who underwent endoscopic evaluation, FLE demonstrated an identical sensitivity (75%) and specificity (86%) to FC in predicting endoscopic inflammation. AUROC was 0.80 for FLE and 0.85 for FC with an optimal cutoff of ≥2+ and 301 μg/g, respectively. When used to distinguish between patients with active IBD and no/inactive IBD, FLE had a sensitivity of 84% and specificity of 90%, comparable with the 84% and 83%, respectively, of FC. AUROC was 0.88 for FLE and 0.91 for FC with an optimal cutoff of ≥2+ and 145 μg/g, respectively. Conclusion FLE demonstrates adequate correlation and comparable accuracy with FC in predicting endoscopic inflammation and distinguishing between patients with active vs inactive IBD.

Abstract
BACKGROUND Fecal calprotectin is largely applied as a non-invasive intestinal inflammation biomarker in human medicine. Previous studies in pigs investigated the levels of fecal calprotectin in healthy animals only. Thus, there is a knowledge gap regarding its application during infectious diarrhea. This study investigated the usefulness of fecal calprotectin as a biomarker of intestinal inflammation in Brachyspira hyodysenteriae and Salmonella Typhimurium infected pigs. RESULTS Fecal samples from pigs with colitis (n = 18) were collected from animals experimentally inoculated with B. hyodysenteriae (n = 8) or from sham-inoculated controls (n = 3). Fecal samples from pigs with enteritis (n = 14) were collected from animals inoculated with Salmonella enterica serovar Typhimurium (n = 8) or from sham-inoculated controls (n = 4). For both groups, fecal samples were scored as: 0 = normal; 1 = soft, wet cement; 2 = watery feces; 3 = mucoid diarrhea; and 4 = bloody diarrhea. Fecal calprotectin levels were assayed using a sandwich ELISA, a turbidimetric immunoassay and a point-of-care dipstick test. Fecal calprotectin levels were greater in colitis samples scoring 4 versus ≤ 4 using ELISA, and in feces scoring 3 and 4 versus ≤ 1 using immunoturbidimetry (P < 0.05). No differences were found in calprotectin concentration among fecal scores for enteritis samples, regardless of the assay used. All samples were found below detection limits using the dipstick method. CONCLUSIONS Fecal calprotectin levels are increased following the development of colitis, but do not significantly change due to enteritis. While practical, the use of commercially available human kits present sensitivity limitations. Further studies are needed to validate the field application of calprotectin as a marker of intestinal inflammation.

Abstract
Background In patients with ulcerative colitis (UC) and Crohn's disease (CD), this research examined the following: prevalence of fecal urgency (hereafter urgency), association of urgency with inflammatory bowel disease (IBD) symptoms and fecal calprotectin, and association between well-being and urgency. Methods In this cross-sectional study from the Study of a Prospective Adult Research Cohort with IBD, urgency was categorized as none, mild, and moderate-severe. We examined the prevalence of urgency, association of urgency with IBD symptoms and fecal calprotectin (in a subset) using multinomial logistic regression, and association of well-being (not feeling well vs generally well) with urgency using logistic regression. Results Among 576 UC patients, 31.4% reported mild and 28.1% moderate-severe urgency. Among 1330 CD patients, 33.8% reported mild and 31.4% moderate-severe urgency. In UC, moderate-severe urgency was associated with: increased average bowel movements/day [odds ratio (OR) 1.23; 95% confidence interval: 1.09, 1.23], increased stool frequency relative to normal (OR, 9.95; 95% CI: 3.21, 30.87), rectal bleeding (OR, 3.36; 95% CI: 1.79, 6.34), moderate-severe abdominal pain (OR, 17.5; 95% CI: 5.38, 56.89), and calprotectin ≥ 250 μg/g (OR, 4.36; 95% CI: 1.50, 12.66). In CD, moderate-severe urgency was associated with: increased average bowel movements/day (OR, 1.23; 95% CI: 1.14, 1.34), increased stool frequency relative to normal (OR, 7.57; 95% CI: 3.30, 17.34), rectal bleeding (OR, 1.77; 95% CI: 1.13, 2.78), and moderate-severe abdominal pain (OR, 7.52; 95% CI: 4.31, 13.14). Reduced well-being was associated with moderate-severe urgency in both UC (OR, 4.20; 95% CI: 1.69, 20.40) and CD patients (OR, 2.52; 95% CI: 1.51, 4.22). Conclusions Urgency was common and associated with symptoms and biomarkers suggesting active IBD and reduced well-being.

Abstract
Background Limited data exist on adherence to fecal calprotectin (FCP) testing in patients with inflammatory bowel disease. Methods Completion rates for patients who had at least one FCP test ordered (n = 3082) and a subgroup with C-reactive protein, complete blood count, and Clostridium difficile tests also ordered (n = 1563) were analyzed. Results More patients completed blood than stool tests, with FCP having the poorest adherence of all tests analyzed. Older patients had higher FCP completion rates. No differences were noted in completion rates across age, gender, or ethnicity for blood tests. Conclusions Further studies are needed to develop strategies that improve the uptake of FCP.

Abstract
OBJECTIVES Reflux is common in infancy; however, persistent signs and symptoms of gastrointestinal distress are often attributed to gastroesophageal reflux disease (GERD). In this pilot study, we aimed to characterize associations between signs and symptoms of suspected GERD and noninvasive markers of intestinal inflammation in preterm infants. METHODS We reviewed Electronic Medical Record (EMR) data to identify clinical signs and symptoms among case patients (n = 16). Controls (n = 16) were matched on gestational age. Univariate and multivariate regression analyses were used to compare fecal calprotectin and urinary intestinal fatty acid binding protein (I-FABP) levels between cases and controls. RESULTS We found no differences in baseline characteristics between cases and controls. In the multivariate regression analysis controlling for the proportion of mother's milk, cases had higher fecal calprotectin levels than controls, with no differences in I-FABP levels between cases and controls. CONCLUSION Our findings suggest that preterm infants with signs and symptoms of GERD have higher levels of intestinal inflammation as indicated by fecal calprotectin compared to their controls. Further studies are needed to evaluate the role of intestinal inflammation in signs and symptoms of gastrointestinal distress and whether fecal calprotectin might have predictive value in diagnosing GERD.

Abstract
Background Primary care faecal calprotectin (FC) was introduced in Leeds in 2014 to distinguish inflammatory bowel disease (IBD) from irritable bowel syndrome and with the hope that it may reduce time to IBD diagnosis and treatment. This study examines the association of FC with referral routes, time to diagnosis, and time to treatment. Methods All patients newly referred to IBD clinics in 2013 and 2016 were studied. Data on referral routes and dates, FC, date of first treatment, and proxy outcomes for disease severity were collected. Results In 248 patients, there were no differences between 2013 and 2016 cohorts regarding baseline data and disease severity. The number of direct referrals to gastroenterology rose from 3% (2013) to 17% (2016), whilst 10% were diagnosed during emergency admissions. Referrals via suspected cancer pathways remained high (38% in 2013, 28% in 2016), whilst many had initial investigations at independent centres (16% in 2013, 24% in 2016). Time from referral to diagnosis was similar between 2013 (0.77 month) and 2016 (1.10 months, p = 0.2). A total of 48 (33.3%) patients had FC checked prior to referral, and 37.5% of these were referred directly to gastroenterology. Time from diagnosis to treatment reduced from 1.37 months (2013) to 0.72 month (2016, p = 0.01). Conclusion Patients present via a multitude of referral pathways, but FC was associated with increased direct referrals to gastroenterology. We found a variation in time to diagnosis and treatment depending on referral routes. Further work is required to ensure patients with suspected IBD get referred to IBD services in a timely manner.

Abstract
BACKGROUND AND OBJECTIVES Necrotizing enterocolitis is a common gastrointestinal disease in newborns, especially in preterm infants. Our study analyzed the value of fecal calprotectin as a biomarker in the diagnosis of NEC based on previous studies that have confirmed elevated calprotectin levels in NEC patients. METHOD We searched several databases including PubMed, Medline, Web of Science and Cochrane Library to identify studies of humans investigating the performance characteristics of fecal calprotectin for the diagnosis of NEC. The quality of included studies was assessed by RevMan5 software (QUADAS-2). The sensitivity, specificity and other measurements of accuracy of fecal calprotectin were pooled using Meta-DiSc software. RESULT A total 10 studies with 568 patients included in our meta-analysis. The pooled sensitivity, specificity, diagnostic odds ratio (DOR) and AUC were: 0.86 (95%CI: 0.80-0.91), 0.79 (95%CI: 0.75-0.83), 34.78 (95% CI: 15.30 to 79.07) and 0.92. The pooled sensitivity, specificity, DOR and AUC of subgroup analysis were: 0.85 (95%CI: 0.79-0.90), 0.89 (95%CI: 0.85-0.92), 41.03 (95% CI: 16.87 to 99.78) and 0.92 for nine studies using ELISA; 0.85 (95%CI: 0.79-0.90), 0.89 (95%CI: 0.85-0.92), 42.08 (95% CI: 18.44 to 96.04) and 0.93 for six prospective studies; 0.91 (95%CI: 0.82-0.97), 0.93 (95%CI: 0.88-0.96), 69.51 (95% CI: 17.67 to 273.40) and 0.95 for four studies of preterm infants. 0.86 (95%CI: 0.77-0.92), 0.94 (95%CI: 0.90-0.97), 53.23 (95% CI: 15.68 to 180.73) and 0.94 five studies that defined NEC as stage II or above. CONCLUSION Fecal calprotectin is a promising biomarker with high diagnostic value in neonatal, especially in premature infants.

Abstract
Ulcerative colitis is an inflammatory condition of the colon. The diagnosis of ulcerative colitis is based on clinical presentation, endoscopic evaluation, and histologic parameters in the absence of demonstrable alternate etiology. The differential diagnosis remains broad, and infection in particular must be considered and excluded. Although laboratory and radiographic findings can aid in the diagnosis of ulcerative colitis, endoscopy remains the gold standard for diagnosis. A correct diagnosis and disease staging are imperative because these factors affect treatment options and prognosis.

Abstract
INTRODUCTION Distinguishing between inflammatory bowel disease (IBD) and functional gastrointestinal disorders is a diagnostic challenge. The need for non-invasive biomarker as a diagnostic tool in the assessment of gastrointestinal symptoms is required. The objectives of current study were to determine the spectrum of clinical features in patients tested for fecal calprotectin presenting with high levels and to compare calprotectin levels among already diagnosed patients known to have IBD as per biopsy findings and documented on patients' file with newly presenting patients who were being investigated and did not have a diagnosis. METHODS This retrospective cross-sectional study was conducted in the Department of Pathology and Laboratory Medicine and Department of Medicine, Aga Khan University, Karachi, Pakistan from January 2017 to December 2019. Subjects tested for fecal calprotectin who had elevated fecal calprotectin levels (n = 150) were included in the current study. Each patient deposited a random stool sample in an airtight container for calprotectin analysis. Biochemical analysis of calprotectin was performed by enzyme-linked immunosorbent assay using epitope calprotectin test kit (Epitope Diagnostics, Italy) on ETI-Max 3000 immunoassay analyzer (DiaSorin, Italy). A structured history form was used for data collection. Results: One hundred and fifty patients were available for inclusion in the final analysis. Majority of the patients (n = 117, 78%) were adults (>18 years of age), and 52.7% (n = 79) were females. Median fecal calprotectin (IQR) was 317.3 μg/g (549.10 - 239.2 μg/g) in children (n = 33) and 305 μg/g (609.9 - 201.6 μg/g) in adults; the difference was statistically non-significant (p value > 0.05). On categorization according to disease, fecal calprotectin levels were significantly elevated (p value = 0.033) in IBD patients compared to normal subjects, 644 μg/g (644 - 587.8 μg/g) vs 308.5 μg/g (505.4 - 233.8 μg/g), respectively. Diarrhea (n = 13, 38.4%), abdominal cramps (n = 12, 36.4%), and weight loss (n = 11, 33.3%) were the most common complaints noted in children with high fecal calprotectin levels, whereas in adults, abdominal cramps (n = 60, 51.3%), diarrhea (n = 59, 50.4%), and weight loss (n = 46, 39.3%) were the common complaints. The median fecal calprotectin levels in children already known to have IBD (n = 3) were higher than the levels noted in children with no diagnosis (n = 30); p value > 0.05. Similarly, median fecal calprotectin levels in adults with IBD (n = 28) were higher than the levels noted in patients with no specific diagnosis (n = 91), 400.7 μg/g (656.6 - 244.3 μg/g) vs 302.7 μg/g (564.6 - 206 μg/g); p value > 0.05. CONCLUSION Current study affirms that the fecal calprotectin test can be used in identifying IBD patients in all age groups.

Abstract
BACKGROUND/AIM Microbial dysbiosis in inflammatory bowel disease (IBD) is poorly understood. Faecal samples collected for the purposes of microbiota analysis are not yet a part of everyday clinical practice. To explore associations between faecal microbiota and disease activity measures in adult IBD patients, for the purpose of possibly integrating microbiota measures in an existing IBD eHealth application for disease-monitoring. METHODS We collected faecal samples from adult IBD patients for one year while they were home-monitoring for disease activity, using faecal calprotectin (FC) and the Simple Clinical Colitis Activity Index (SCCAI). Faecal samples were analysed in two different ways: commercially available test consisting of 54 pre-determined bacterial markers (DNA test) and 16S rRNA gene sequencing (16S-seq). Univariable linear mixed effect models were fitted to predict disease scores using normalised relative abundances as fixed effects. RESULTS Seventy-eight IBD patients provided a total of 288 faecal samples for microbiota analysis. Two hundred and thirty-four of the samples were from patients with ulcerative colitis (UC). Peptostreptococcus anaerobius was found to correlate significantly with increasing FC, while an additional 24 genera were found to be associated with FC and/or SCCAI (16S-seq). Bacterial markers (DNA test) for Proteobacteria, Shigella spp. and Escherichia spp., were significantly correlated with increasing FC measures, while another 14 markers were found to be associated with FC and/or SCCAI. CONCLUSIONS In patients with UC, results of both methods are associated with disease activity, correlating significantly with Peptostretococcus anaerobius (16S-seq) and with Proteobacteria, Shigella spp. and Escherichia spp. (DNA test).

Abstract
The term IBD is usually used for referring to a group of inflammatory gastro-intestinal diseases (mainly Crohn's disease and ulcerative colitis). Accordingly, IBD arises as a result of inappropriate immune response to intestinal commensal organisms among genetically susceptible individuals. Performing colonoscopy and histopathologic evaluation on an inflamed bowel biopsy specimen are currently considered as gold standards for diagnosis and management of IBD. Correspondingly, these techniques are known to be invasive and costly. In recent decades, fecal calprotectin, as a biomarker, has received much attention for the diagnosis and non-invasive management of IBD. Up to now, many studies have investigated the efficacy of fecal calprotectin in the areas of IBD differentiation from IBS, prediction of endoscopic and histologic activities of IBD and prediction of disease recurrence. Although some of these studies have reported promising results, some others have shown significant limitations. Therefore, in this paper, we reviewed the most interesting ones of these studies after a brief discussion of the laboratory measurement of fecal calprotectin. Moreover, we attempted to provide an answer for the question of whether fecal-calprotectin could be considered as a potential surrogate marker for colonoscopy.

Abstract
BACKGROUND/AIMS Specific serum markers reflecting hepatic inflammation and fibrosis are required to tailor the treatment strategies in non-alcoholic steatohepatitis (NASH). We aimed to investigate the roles of myeloperoxidase (MPO) and calprotectin in predicting the hepatic inflammation status and disease severity in NASH. MATERIALS AND METHODS A total of 48 patients with biopsy-proven NASH and 25 healthy volunteers with normal weight were prospectively enrolled. Serum MPO and calprotectin levels were compared between the NASH and control groups. Hepatic MPO and calprotectin expressions were compared in terms of histologic non-alcoholic fatty liver disease activity scores (NAS) (low NAS [≤4] vs. high NAS [>5]) and fibrosis stage (insignificant [F0-1]/significant [F2-4]). RESULTS Serum MPO and calprotectin levels were not significantly different between the NASH and control groups. In the subgroup analysis, hepatic MPO expression was significantly increased in patients with NASH with significant fibrosis than in those with insignificant fibrosis (F2-4: 7.04±3.61 vs. F0-1: 4.83±2.42, p=0.01). We found no difference between the groups with low and high NAS with regard to serum MPO and calprotectin levels and hepatic MPO and calprotectin expressions. CONCLUSION This study demonstrated that hepatic MPO expression can reflect advanced fibrosis in NASH. However, when serum MPO and calprotectin levels were evaluated as potential serum markers, both did not associate with hepatic inflammation status and fibrosis stage in NASH. Therefore, our study results preclude their use as serum markers for hepatic inflammation in NASH.

Calprotectin is a calcium and zinc-binding protein, formed by a hetero complex of S100A8 and S100A9 proteins, which belong to the S-100 protein family consisting in more than 20 different proteins with a tissue-specific expression pattern. This protein is secreted extracellularly from stimulated neutrophils or released by cell disruption or death. The presence of calprotectin in feces quantitatively relates to neutrophil migration toward the gastrointestinal (GI) tract; thus, it represents a useful marker of intestinal inflammation. Fecal calprotectin (FC) has been proven largely useful for determining the inflammatory origin of GI symptoms differentiating between organic and non-organic diseases. Indeed, increased FC levels are also seen in gastroenteritis, microscopic colitis, polyps, malignancies and cystic fibrosis. To date, there are many evidences regarding usefulness in the detection of fecal calprotectin for the management of gastrointestinal disorders, both in children and adults but, especially in the pediatric population, still clear indications for its use are lacking. Its incorporation in primary care reduces the risk of missing an organic disease and facilitates the indication for expensive and invasive investigations as colonoscopy. We herein review and discuss the last evidence on the usefulness of FC in children, with its current indications and future prospective.

Abstract
Although lacking validated cutoff values, fecal calprotectin (FC), besides C-reactive protein, is considered the standard test for assessing disease activity in Crohn's disease (CD). The aim of the present review is to provide a general overview of the literature addressing the role of FC in the clinical and endoscopic assessment of disease activity in CD, seeking correlations with capsule endoscopy, response to therapy, prediction of relapse, and postoperative recurrence. A systematic search of the literature up to September 2019 was performed using Medline, Embase, and the Cochrane Library. Only papers written in English concerning FC in adult patients affected by CD were included. Pediatric studies, in vitro studies, animal studies, studies on blood/serum samples, and studies analyzing FC in ulcerative colitis or in both CD and ulcerative colitis were excluded. Out of 713 citations, 65 eligible studies were identified. FC showed high accuracy in the assessment of intestinal inflammation and response to therapy, in particular in colonic disease, thus proving a good surrogate marker for these aims. FC is useful in identifying patients at high risk for endoscopic relapse or postoperative recurrence, for optimizing or downstage therapy. Unfortunately, FC performs less well in small bowel CD. FC is an effective fecal marker in the management of CD patients, optimizing the use of endoscopic procedures. Owing to its diagnostic accuracy, FC may represent a cornerstone of the "treat-to-target" management strategy of CD patients.

Abstract
Objective: Fecal calprotectin (FC) has been widely used for a clinical marker of intestinal inflammation in children and adults. However, the clinical usefulness has not been determined in neonates. The purpose of this study was to investigate the change of FC and associated clinical factors in neonates. Methods and Materials: In total, 146 neonates among 472 admissions to our NICU between 2018 and 2019 were included, and 242 stool samples were collected. FC was measured in the first, second, and third-fourth week after birth, respectively, using commercial ELISA. The clinical characteristics were reviewed from medical records. Statistical analyses were performed to analyze associated factors regarding on changes of fecal calprotectin. Results: A wide range from 5.5 to 6,000 mg/kg of FC was observed in neonates. FCs during neonatal period were not correlated with the gestational age at birth or birth weight. The meconial calprotectin was higher than FCs after 2 weeks of age (n = 134, 418.06 vs. 243.12 in the second week and 259.58 in the third week after birth). Meconial calprotectin was associated with birth weight and meconium stained amniotic fluid. FC during the neonatal period decreased with postnatal week (-464.93 ± 158.02 at third-fourth week after birth compared with the 1st week, P = 0.004) and breast milk (-337.27 ± 150.51 compared with formula milk, P = 0.026). Conclusion: Fecal calprotectin tended to decrease with postnatal week during the neonatal period, and breast milk could affect more decrease of FC.

Abstract
Autism spectrum disorder (ASD) is a neurodevelopmental condition with increasing incidence. Recent evidences suggest glial cells involvement in autism pathophysiology. S100B is a calcium binding protein, mainly found in astrocytes and therefore used as a marker of their activity. In our study, children with autism had higher plasma concentrations of S100B compared to non-autistic controls. No association of S100B plasma levels with behavioral symptoms (ADI-R and ADOS-2 scales) was found. Plasma S100B concentration significantly correlated with urine serotonin, suggesting their interconnection. Correlation of plasma S100B levels with stool calprotectin concentrations was found, suggesting not only brain astrocytes, but also enteric glial cells may take part in autism pathogenesis. Based on our findings, S100B seems to have a potential to be used as a biomarker of human neurodevelopmental disorders, but more investigations are needed to clarify its exact role in pathomechanism of autism.

Abstract
BACKGROUND Information on the use of fecal markers in microscopic colitis screening is limited. AIM To evaluate the risk variables associated with a diagnosis of microscopic colitis including fecal calprotectin. METHODS Patients submitted for a colonoscopy due to chronic watery diarrhea fulfilling criteria of functional disease were evaluated. Colonic mucosa was normal but mild erythema and edema was allowed. Fecal calprotectin was analyzed. A logistic regression was used to evaluate variables associated with both raised fecal calprotectin and a diagnosis of microscopic colitis. RESULTS 94 patients were included, 30 were diagnosed with microscopic colitis and 64 made up the control group. Median calprotectin levels were 175 (IQR, 59-325) for the microscopic colitis and 28 (IQR, 16-111) for the control group (p < 0.001). The optimal cut-off for fecal calprotectin was >100 μg/g (AUC, 0.73), with 67% sensitivity and 75% specificity. The number of drugs used ≥3 (OR, 3.9; CI, 1.4-10.4) and microscopic colitis diagnosis (OR, 6; CI, 2.2-16.3) were associated with raised calprotectin levels. Age >60 years (OR, 3.8; CI, 1.4-10.1) and calprotectin levels (OR, 5.3; CI, 2-14.1) were associated with a risk of microscopic colitis. CONCLUSIONS Elevated fecal calprotectin concentrations are often seen in microscopic colitis, and may be helpful in the diagnosis of women over 60 with chronic watery diarrhea.

Abstract
Background: Non-invasive markers for predicting relapse would be a useful tool for the management of patients with inflammatory bowel disease. Eosinophil granulocytes and their granule proteins eosinophil cationic protein (ECP) and eosinophil-derived neurotoxin (EDN) have previously been shown to reflect disease activity in Crohn's disease and ulcerative colitis.Aim: To examine the capacity of faecal ECP and EDN to predict relapse in ulcerative colitis and Crohn's disease, and to compare these proteins with faecal calprotectin.Methods: Patients with Crohn's disease (n = 49) and ulcerative colitis (n = 55) were followed prospectively until relapse or end of the two-year study period. Faecal samples were obtained every third month. The predictive value of ECP and EDN was assessed in Cox regression models.Results: In ulcerative colitis, a doubled EDN or ECP concentration was associated with a 31% and 27% increased risk of relapse, respectively. EDN levels were increased both at relapse and three months prior. By contrast, in Crohn's disease, the concentration of EDN was higher among patients in remission than in those who relapsed. Correlations between faecal calprotectin, ECP and EDN were observed in both diseases.Conclusions: We demonstrate that the risk of relapse in ulcerative colitis can be predicted by consecutively measuring faecal EDN every third month, and suggest EDN as a complementary faecal marker to calprotectin to predict future relapse in ulcerative colitis. Our finding of higher EDN in Crohn's disease-patients staying in remission than in those who relapsed indicates different functions of the protein in ulcerative colitis and Crohn's disease.

Abstract
Background/Aims Fecal calprotectin (FC) is a marker of intraluminal intestinal inflammation. Intestinal inflammation may contribute to the pathophysiology of irritable bowel syndrome (IBS). This study evaluated FC levels in children with IBS and differences in FC levels in children stratified by IBS subtype and healthy controls (HCs). Methods A total of 157 children with IBS and 56 HCs aged 4–16 years (119 boys, 94 girls, mean age of 9.48 years) were included in this prospective study. Children with IBS were diagnosed using the Rome III criteria and classified into 4 subtypes: IBS with constipation (IBS-C, n=37), IBS with diarrhea (IBS-D, n=54), IBS with alternating constipation and diarrhea (IBS-M, n=49), and IBS unsubtyped (IBS-U, n=17); postinfectious IBS (PI-IBS) was also considered. The FC concentration in stool samples was analyzed using an enzyme-linked immunosorbent assay. All participants answered a questionnaire regarding several demographic and clinical characteristics. Results Children with IBS had significantly higher levels of FC than the HCs (88.71 μg/g vs. 17.77 μg/g). Among the 4 IBS subtypes, the FC concentration was highest in children with IBS-D, followed by those with IBS-M, IBS-C, and IBS-U (169.94 μg/g vs. 45.04, 31.22, and 33.52 μg/g, respectively), and these differences were statistically significant. For PI-IBS, 90% of cases were in the IBS-D group. Conclusions The FC level was significantly higher in children with IBS than in HCs and differed depending on the IBS subtype, supporting the notion that IBS is a type of low-grade bowel inflammation.

Abstract
BACKGROUND Immunothrombosis is a physiological process based on the release of neutrophil extracellular traps (NETs) to immobilise, contain and kill bacteria. This is an innate immune response in which the local activation of blood coagulation exerts the critical protective function during microbial infection. In recent years, there has been much interest in the adult literature about the key role of immunothrombosis in pathologic states including thrombosis, cancer, sepsis and trauma. Currently, little research has been done into its role in paediatric conditions. METHODS We conducted a literature search of the National Library of Medicine (MEDLINE/PubMed) from the years 2000 to May 2018 and qualitatively identified 24 relevant papers. References of articles included for full-text review were checked for relevant publications. RESULTS Our aim is to summarise the most relevant evidences regarding an excessive production or defective removal of NETs in paediatric conditions. In particular, we have divided the role of immunothrombosis into acute (sepsis, necrotising enterocolitis, otitis media, neonatal arterial ischaemic stroke, haemolytic anaemic diseases) and chronic (systemic lupus erythematous, type 1 diabetes mellitus, respiratory diseases, graft-versus-host disease) conditions to find important similarities in their pathophysiology. CONCLUSION The field of immunothrombosis in paediatric conditions is still in its infancy. We have presented multiple pathways of NET-induced disease together with possible areas of future research and treatments.

Abstract
Irritable bowel syndrome (IBS) is a prolonged and disabling functional gastrointestinal disorder with the incidence rate of 18% in the world. IBS could seriously affect lifetime of patients and cause high economic burden on the community. The pathophysiology of the IBS is hardly understood, whereas several possible mechanisms, such as visceral hypersensitivity, irregular gut motility, abnormal brain-gut relations, and the role of infectious agents, are implicated in initiation and development of this syndrome. Different studies demonstrated an alteration in B-lymphocytes, mast cells (MC), T-lymphocytes, and cytokine concentrations in intestinal mucosa or systemic circulation that are likely to contribute to the formation of the IBS. Therefore, IBS could be developed in those with genetic predisposition. Infections' role in initiation and exacerbation of IBS has been investigated by quite several clinical studies; moreover, the possible role of some pathogens in development and exacerbation of this disease has been described. It appears that the main obligatory pathogens correspond with the IBS disease, Clostridium difficile, Escherichia coli, Mycobacterium avium subspecies paratuberculosis, Campylobacter concisus, Campylobacter jejuni, Chlamydia trachomatis, Helicobacter pylori, Pseudomonas aeruginosa, Salmonella spp, Shigella spp, and viruses, particularly noroviruses. A number of pathogenic parasites (Blastocystis, Dientamoeba fragilis, and Giardia lamblia) may also be involved in the progression and exacerbation of the disease. Based on the current knowledge, the current study concludes that the most common bacterial, viral, and parasitic pathogens may be involved in the development and progression of IBS.

AIM The faecal calprotectin (FC) test is increasingly being used in clinical practice to help select children with gastrointestinal symptoms who might have inflammatory bowel disease (IBD) and benefit from endoscopies. We provide an overview of the advantages and limitations of the FC test. METHODS PubMed was searched for meta-analyses that had investigated the diagnostic accuracy of the FC test and the pooled sensitivity and specificity for distinguishing IBD from non-IBD patients were used to calculate likelihood ratios (LR). These were applied to practical examples to explain how easily clinicians can use the results to modify pre-test probabilities of IBD and generate post-test probabilities for IBD. RESULTS The positive LR and negative LR of the FC test were 2.8 and 0.015, respectively. The usefulness of the FC test depended on the pre-test probability of IBD. When the pre-test probability of IBD was low, a positive FC test did not necessarily indicate IBD. However, because of the very small negative LR, a negative FC result virtually ruled out IBD in most cases. CONCLUSION The FC test should not be used indiscriminately in children with gastrointestinal symptoms but should be targeted at those who are likely to have IBD.

Reference intervals for stool calprotectin in preterm neonates and their utility for the diagnosis of necrotizing enterocolitis. J Perinatol 2018; 38:1379-1385. [PMID: 29740189 DOI: 10.1038/s41372-018-0108-9] [Citation(s) in RCA: 17] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/04/2017] [Revised: 02/27/2018] [Accepted: 03/07/2018] [Indexed: 01/01/2023]
Abstract
OBJECTIVE Calprotectin is an antimicrobial protein found in stool when released by granulocytes. We sought to create stool calprotectin reference ranges in preterm neonates and to evaluate whether levels exceeding the upper reference interval are diagnostic for necrotizing enterocolitis (NEC). STUDY DESIGN Stool calprotectin was measured in premature neonates without gastrointestinal pathology to create reference intervals. For comparison, levels from infants undergoing "rule out NEC" evaluations were plotted on these reference intervals. RESULTS Stool calprotectin reference intervals were created according to gestational age at birth and corrected gestational age. Levels during "rule out NEC" evaluations were more often above the upper reference interval with NEC vs. those without NEC. CONCLUSIONS Stools from preterm neonates have a higher range of calprotectin than stools from healthy term neonates. In evaluating preterm neonates for NEC with stool calprotectin, a calprotectin upper reference interval that incorporates corrected gestational age best predicts the diagnosis of NEC.

Abstract
Autism spectrum disorders (ASD) are neurodevelopmental disorders characterized by impaired social interaction and communication, as well as repetitive behavior and restricted interests. There is convincing evidence that the intestinal inflammation is involved in etiology of ASD. Increased levels of inflammatory markers were shown to be associated with more aberrant behaviors and communication of subjects with ASD. Calprotectin in the feces is produced by activated neutrophils and epithelial cells of the gut mucosa, and its levels reflect local inflammation of the gastrointestinal tract. Concentration of fecal calprotectin was determined by ELISA method in 87 individuals with ASD and 51 controls, of that 29 siblings of children with ASD and 22 non-related controls. In non-relatives significantly lower values of fecal calprotectin were observed than in both subjects with ASD and their siblings. In the group with ASD significant correlations of fecal calprotectin with all domains of the ADI-R diagnostic tool were found: qualitative abnormalities in reciprocal social interaction and communication, restrictive and repetitive patterns of behavior. Results suggest that low grade intestinal inflammation may be one of factors implicated in the pathophysiology of ASD.

Abstract
BACKGROUND AND PURPOSE Traditionally, elastase has been used to study exocrine activity of the pancreas in patients with chronic pancreatitis and cystic fibrosis, and calprotectin as a marker for gut-wall inflammation in patients with inflammatory bowel disease. The aim of the study was to find out whether elastase and calprotectin could be used as inflammatory markers for radiation-induced gut wall injury of the distal bowel. MATERIAL AND METHODS Adult male mice were exposed to two, three, or four fractions of 6 Gy or 8 Gy irradiation to the sigmoid and rectum of the large bowel, using a linear accelerator. Fecal samples were collected from mice at 1, 3, and 6 weeks post-irradiation. The fecal levels of elastase and calprotectin were analyzed using ELISA. RESULTS Three and 6 weeks after irradiation, we found a dose-effect relationship between dose of ionizing radiation and the fecal level of elastase; that is significantly higher levels of elastase were observed in mice that had received a high irradiation dose. We also found that irradiated mice hosted in the same cage had a comparable level (either high or low) of elastase. No significant differences were observed from the calprotectin data. CONCLUSIONS We found a clear association between the dose of ionizing radiation to the distal colon and the level of elastase in the fecal samples.

Abstract
BACKGROUND Penile lymphoedema (with and without cellulitis) is a rare, often chronic, clinically heterogeneous entity with an uncertain pathogenesis and an important differential diagnosis. It creates significant physical and psychosexual morbidity, and presents considerable therapeutic challenges. The existing literature is limited. AIM To describe and share our updated cumulative experience of a cohort of patients with penile lymphoedema. METHODS This was a retrospective review of the case records of patients with chronic penile lymphoedema seen in two dedicated male genital dermatology clinics between January 2011 and July 2016. RESULTS In total, 41 cases were identified. Over a third had Crohn disease (CD) (which was occult in one-third of these), and over a third had serological evidence of streptococcal infection. All patients responded to systemic antibiotics and specialized urological surgery circumcision and excision). CONCLUSIONS Penile lymphoedema should be investigated to exclude underlying pathology especially CD and streptococcal infection. Treatment with antibiotics should be considered early and long term to try to preserve the foreskin: most patients are uncircumcised. Some patients may benefit from a course or courses of oral steroids. The development of gross dysfunction of the prepuce usually dictates circumcision and excision of lymphoedematous tissue once the situation is medically stabilized.

Abstract
BACKGROUND AND GOALS The use of fecal calprotectin (FC) as a stool biomarker for differentiating inflammatory bowel disease (IBD) from IBS has been well validated, and there is a strong correlation between FC and the presence of endoscopic inflammatory lesions. However, recent studies have demonstrated intraindividual sample variability in patients with IBD, possibly limiting the reliability of using a single sample for monitoring disease activity. Our aim was to assess the within-stool and within-day sample variability of FC concentrations in patients with IBD. STUDY We examined a cross-sectional cohort of 50 adult IBD patients. Eligible patients were instructed to collect 3 samples from different parts of the stool from their first bowel movement of the day and 3 samples from each of up to 2 additional bowel movements within 24 hours. FC concentrations were measured by a rapid, quantitative point-of-care test using lateral flow technology (Quantum Blue). Descriptive statistics were used to assess FC variability within a single bowel movement and between different movements at different FC positivity cutoffs. RESULTS Within a single bowel movement, there was clinically significant sample variability ranging from 8% to 23% depending on the time of the day or on the FC positivity cutoff value. Between bowel movements, there was clinically significant sample variability ranging from 13% to 26% depending on the FC positivity cutoff. CONCLUSIONS Considering a single FC sample, the first sample of the day with an FC positivity cutoff of 250 μg/g provided the most reliable indication of disease activity.

Abstract
OBJECTIVE Accurate differentiation between Crohn's disease (CD) and UC is important to ensure early and appropriate therapeutic intervention. We sought to identify proteins that enable differentiation between CD and UC in children with new onset IBD. DESIGN Mucosal biopsies were obtained from children undergoing baseline diagnostic endoscopy prior to therapeutic interventions. Using a super-stable isotope labeling with amino acids in cell culture (SILAC)-based approach, the proteomes of 99 paediatric control and biopsies of patients with CD and UC were compared. Multivariate analysis of a subset of these (n=50) was applied to identify novel biomarkers, which were validated in a second subset (n=49). RESULTS In the discovery cohort, a panel of five proteins was sufficient to distinguish control from IBD-affected tissue biopsies with an AUC of 1.0 (95% CI 0.99 to 1.0); a second panel of 12 proteins segregated inflamed CD from UC within an AUC of 0.95 (95% CI 0.86 to 1.0). Application of the two panels to the validation cohort resulted in accurate classification of 95.9% (IBD from control) and 80% (CD from UC) of patients. 116 proteins were identified to have correlation with the severity of disease, four of which were components of the two panels, including visfatin and metallothionein-2. CONCLUSIONS This study has identified two panels of candidate biomarkers for the diagnosis of IBD and the differentiation of IBD subtypes to guide appropriate therapeutic interventions in paediatric patients.

Abstract
BACKGROUND Fecal calprotectin (FC) is non-invasive inflammatory marker indicating various bowel diseases. However, the median-specific cut-off values and the standard deviations (SD) of the FC levels in each age group <4 years were not elucidated. METHODS Healthy volunteers were enrolled from four kindergartens. A questionnaire was used to confirm that the children met the inclusion criteria, and several demographics and history of bowel symptoms were collected. The FC level was measured. RESULTS A total of 234 healthy children aged between 6 months and 4 years were recruited. The median FC concentration of all participants was 245 μg/g (range 12-1033 μg/g, mean 68.5 μg/g, SD 123.12 μg/g). The children were divided into six age groups. The upper limit of 95% CI of median FC values was 135 μg/g in 7-12 months group, 65 μg/g in 13-18 months group, 55 μg/g in 19-24 months group, 40 μg/g in 25-30 months group, 21 μg/g in 31-36 months group, and 12 μg/g in 37-48 months group. A negative correlation trend was found between the age and the FC concentration. CONCLUSION This is the first study to present the FC median levels in the specific age groups <4 years in Korea. We found a FC level reduction with age, indicating a bowel maturation process and decreased intestinal permeability of the intestinal mucosa. In our study, FC levels reached the values of 50 μg/g around the age of 2 years.

Abstract
BACKGROUND The use of fecal calprotectin (FCal) as a marker of intestinal inflammation, in the management of inflammatory bowel disease (IBD) is increasing. The aim of this study was to examine the impact of FCal measurements on decision-making and clinical care of children with IBD. MATERIALS AND METHODS In a retrospective cohort study, FCal, clinical activity indices, and blood markers were measured in children with established diagnoses of IBD. Pearson correlation coefficient analysis was performed to examine association between FCal and other markers. Decisions based on FCal measurements were prospectively documented and participants were evaluated 3-6 months later. RESULTS A total of 115 fecal samples were collected from 77 children with IBD [median age 14, interquartile range (IQR) 11-15.6 years, 42 females, 37 with Crohn's disease]. FCal positively correlated with clinical activity indices (r = 0.481, P < 0.05) and erythrocyte sedimentation rate (r = 0.40, P < 0.05) and negatively correlated with hemoglobin (r = -0.40, P < 0.05). Sixty four out of 74 (86%) positive FCal measurements (≥250 μg/g of stools) resulted in treatment escalation with subsequent significant clinical improvement while in the FCal negative group, 34 out of 41 (83%) measurements resulted in no change in treatment and were associated with remission on follow-up. CONCLUSION Based on high FCal, the majority of children had treatment escalation that resulted in clinical improvement. FCal measurements were useful and reliable in decision-making and clinical care of children with IBD.

Abstract
OBJECTIVE Neonates with necrotizing enterocolitis (NEC) have higher calprotectin levels in stool than do healthy neonates. However, it is not known whether high stool calprotectin at the onset of bowel symptoms identifies neonates who truly have NEC vs other bowel disorders. STUDY DESIGN Neonates were eligible for this study when an x-ray was ordered to 'rule-out NEC'. Stool calprotectin was quantified at that time and in a follow-up stool. Each episode was later categorized as NEC or not NEC. The location of calprotectin in the bowel was determined by immunohistochemistry. RESULTS Neonates with NEC had higher initial and follow-up stool calprotectin levels than did neonates without NEC. Calprotectin in bowel from neonates with NEC was within neutrophil extracellular traps (NETs). CONCLUSION At the onset of signs concerning for NEC, fecal calprotectin is likely to be higher in neonates with NEC. Calprotectin in their stools is exported from neutrophils via NETs.

Abstract
Biomarkers have gained increasing attention for the diagnosis and follow-up of inflammatory bowel disease (IBD). Endoscopy remains the gold standard for assessing disease activity. Biomarkers are rapid, inexpensive, and noninvasive, and can be used in different stages of the disease with high sensitivity and specificity. Calprotectin and tests for C-reactive protein are used to assess the disease activity, predict relapse, and monitor treatment response. New noninvasive tests are being studied. This review discusses current evidence for these surrogate markers, their potential clinical applications, and limitations in disease management. We highlight recent advances in IBD biomarkers and future uses.

Abstract
The research was performed to explore the diagnosis value of dynamic serum calprotectin (SC) expression for sepsis in postoperative intensive care unit patients. One hundred sixty-three patients who met the inclusion criteria served as the study group. All cases in the study group were further divided into the sepsis subgroup (51 cases) and the nonsepsis subgroup (112 cases). Fifty healthy volunteers served as the control group. The levels of SC and other laboratory indexes including complete blood counts, leukocytes, the immature-to-total-neutrophil ratio, procalcitonin (PCT), C-reactive protein, and blood lactate were detected, cytokines [interleukin (IL)-2, IL-6, and interferon-γ] released by neutrophils were also determined. The Acute Physiology and Chronic Health Evaluation II (APACHE II) score and the Sequential Organ Failure Assessment score were calculated. The factors related to prognosis were analyzed with multivariate logistic regression analysis. The diagnostic accuracies of ΔSC [the differences of SC levels between postoperative day (POD) 1 and POD 2, 3, 5, 7] and ΔPCT (the differences of PCT levels between POD 1 and POD 2, 3, 5, 7) on sepsis were compared with other markers for sepsis. The levels of SC and cytokines were markedly increased on POD 1, 2, 3, 5, and 7 in the study group compared with the control group (P < 0.05 or P < 0.01). The same results were found in the sepsis subgroup compared with the nonsepsis subgroup (P < 0.05 or P < 0.01). Significant positive correlations between SC and cytokines were confirmed in patients of the study group (P < 0.05 or P < 0.01). APACHE II scores and the levels of SC and PCT on POD 1 were the variables significantly associated with sepsis. The diagnostic accuracies of ΔSC1-3 (sensitivity 87%, specificity 89%) and ΔPCT1-3 (sensitivity 89%, specificity 90%) for sepsis were greater than other ΔSCs and ΔPCTs. It appears that the dynamic changes in SC are of the predictive values for septic patients after major surgeries.

Abstract
Chronic diarrhoeal illnesses with nausea and weight loss are a common indication for gastroenterology review. While many such cases have intra-luminal aetiologies, such as inflammatory bowel disease, coeliac disease or other malabsorptive conditions, with many other cases due to functional gut disorders or systemic malignancy, clinicians must also keep vascular disorders in mind. Here we report a patient with a delayed diagnosis of chronic mesenteric ischaemia after 6 months of gastrointestinal symptoms strongly mimicking an alternative diagnosis such as inflammatory bowel disease due an atypical predominance of nausea and diarrhoea rather than pain. We briefly review the literature on treatment of this condition but also discuss with particular attention the sequence of cognitive errors made by clinicians that led to a diagnostic delay, inviting readers to thus reflect on how such errors can be minimised in their practice.

Abstract
Though distinct in terms of pathology, natural history and therapeutic approach, irritable bowel syndrome (IBS) and inflammatory bowel disease (IBD) have some features in common. These include shared symptomatology and largely similar demographics. However, in most instances, clinical presentation, together with laboratory, imaging and endoscopic findings will readily permit the differentiation of active IBD from IBS. More problematic is the situation where a subject with IBD, in apparent remission, continues to complain of symptoms which, in aggregate, satisfy commonly employed criteria for the diagnosis of IBS. Access to methodologies, such the assay for levels of calprotectin in feces, now allows identification of ongoing inflammation in some such individuals and prompts appropriate therapy. More challenging is the IBD patient with persisting symptoms and no detectable evidence of inflammation; is this coincident IBS, IBS triggered by IBD or an even more subtle level of IBD activity unrecognized by available laboratory or imaging methods? Arguments can be advanced for each of these proposals; lacking definitive data, this issue remains unresolved. The occurrence of IBS-type symptoms in the IBD patient, together with some data suggesting a very subtle level of 'inflammation' or 'immune activation' in IBS, raises other questions: is IBS a prodromal form of IBD; and are IBS and IBD part of the spectrum of the same disease? All of the available evidence indicates that the answer to both these questions should be a resounding 'no'. Indeed, the whole issue of overlap between IBS and IBD should be declared moot given their differing pathophysiologies, contrasting natural histories and divergent treatment paths. The limited symptom repertoire of the gastrointestinal tract may well be fundamental to the apparent confusion that has, of late, bedeviled this area.
