[PMID: 34531137 DOI: 10.1016/j.ajg.2021.05.020] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/28/2020] [Revised: 05/10/2021] [Accepted: 05/31/2021] [Indexed: 10/20/2022]
Abstract
BACKGROUND AND STUDY AIMS This study aimed to investigate the prevalence of intestinal inflammation in patients with ankylosing spondylitis (AS) by assessing fecal calprotectin (FC) levels and comparing them with those in patients with rheumatoid arthritis (RA) and non-inflammatory rheumatic diseases. Our secondary aim was to correlate FC levels with antirheumatic treatment, nonsteroidal anti-inflammatory drug (NSAID) usage, and disease activity measures. PATIENTS AND METHODS This cross-sectional study included 97 patients with AS fulfilling the modified New York criteria, 48 patients with RA fulfilling the American College of Rheumatology criteria, and 49 patients with non-inflammatory rheumatic diseases. All patients were questioned about intestinal complaints, and symptomatic patients were excluded. Disease activity was measured in the AS and RA patient groups. RESULTS The AS group had a significantly higher FC test positivity rate than the RA group (p = 0.016). Furthermore, the AS group had FC levels that were negatively correlated with disease duration (p = 0.04). FC levels were not correlated with any disease activity index, erythrocyte sedimentation rate, C-reactive protein, uveitis, or peripheral arthritis. Patients with AS who used NSAIDs had significantly higher FC levels than nonusers (p = 0.001). CONCLUSIONS This study revealed that 11% of patients with AS without intestinal complaints had elevated FC levels. FC levels were not correlated with disease activity in AS. Subclinical intestinal inflammation was higher in the early stages of AS. The AS group had a significantly higher FC test positivity than the RA group. In the AS group, NSAID users had significantly higher FC levels than nonusers; thus, no statistically significant difference was observed between biological agent users and nonusers.

Abstract
Calprotectin, also known as S100A8/A9, has been linked to gut inflammation caused by IgE-mediated food hypersensitivities, but the pathophysiologic abnormalities it causes remain to be determined. We created a mild food hypersensitivity model through oral gavage of ovalbumin in Norway brown rats without using immune adjuvant. Changes in the levels of calprotectin and inflammation-associated cytokines were then observed over time. We found that fecal calprotectin as well as jejunal and liver TLR4, TNF-α, NF-κB, IL-1β, and IL-6 were upregulated in hypersensitive rats. Additionally, the influence of calprotectin on CD4+ T and dendritic cells was observed by co-culturing CD4+ T cells with dendritic cells, which revealed a shift toward increased Th2 T cells in calprotectin-treated cultures. These results suggest that calprotectin, along with other inflammatory factors, promotes the inflammation seen in mild food allergy.

Abstract
Chronic abdominal pain (CAP) remains a particular challenge because of its complicated causes, especially when the disorders involve the small bowel, where it is quite difficult to intubate the flexible endoscopes. This study was to investigate the small bowel diseases detected by capsule endoscopy (CE) in CAP patients to evaluate the role of CE on CAP, and analyzed the relationship among the clinical characteristics of CAP patients and the positive rates of CE findings to search for the indications of CE for CAP patients.This retrospective study included 341 patients with CAP defined as recurrent abdominal pain for no <3 months. Each patient underwent CE after a negative diagnostic work-up. All CE images were reviewed by 3 gastroenterologists independently. The positive findings were defined as abnormal findings in the small bowel that might have been the causes of CAP. The final diagnosis was confirmed by CE findings, clinical features, histopathology, and a response to the treatment during the follow-up for at least 3 months after CE.The overall positive rate of CE findings was 28.15% (96/341). The positive rate in CAP-A (CAP with associated symptoms) group was significantly higher than that in CAP-O (CAP only) group (33.16% vs 21.38%, P = .017). Multivariate logistic regression analysis revealed that weight loss (odds ratio [OR] = 2.827, 95% confidence interval (CI) = 1.938-4.926), hypoalbuminemia (OR = 6.142, 95%IC = 4.129-8.274), elevated erythrocyte sedimentation rate (ESR) (OR = 4.025, 95%IC = 3.178-6.892), or increased C-reactive protein (CRP) (OR = 7.539, 95%CI = 5.365-11.723) were significantly associated with high positive rates. On follow-up, final diagnosis was confirmed in 56 of 69 (81.16%) patients with positive CE findings. About half of these patients (46.38%, 32/69) were diagnosed as inflammatory diseases, including Crohn disease (12), tuberculosis (5), NSAID enteropathy (4), etc. Tumors were proved in 21.74% (15/69) patients, including malignant in 7 cases and benign in 8 cases. Parasitosis was found in 9 (13.04%) patients.This study suggests that CE may be helpful for CAP patients to detect the small bowel diseases, half of which were comprised of inflammatory diseases. Besides, weight loss, hypoalbuminemia, elevated ESR, or increased CRP may be regarded as the indications of CE for CAP patients.

Abstract
INTRODUCTION Endoscopy is integral to the diagnosis and management of many gastrointestinal problems in children. Recently the number of endoscopic procedures performed has increased considerably worldwide raising questions about their appropriateness and cost-efficacy. OBJECTIVES The aim of the study was to determine the diagnostic yield (the likelihood that a procedure or test will provide information required to establish a diagnosis) of endoscopy in a paediatric population in a large tertiary referral centre and to determine the terminal ileum intubation (TII) rate of paediatric ileocolonosocopy (IC) in an active training environment and compare with previously calculated rates. METHODS Random selection of cases from a theatre electronic database from a 30-month period covering April 2012 to October 2014. The data were collected for initial presenting symptoms; age at diagnosis; indications for endoscopy; endoscopic findings; histopathological findings; and any change in management postendoscopic procedure. The diagnostic yield of the endoscopies and the TII rate of IC were calculated. Change in and contribution to management was assessed. RESULTS Median age 9.58 (0.5-16.5) years and M:F ratio 1:1.42. The positive diagnostic yield was 18.9% for oesophago-gastro-duodenoscopy alone, 32.6% for IC alone, and 39.2% when both occurred. In 45% management was actively changed due to endoscopy/histopathology findings and a significant management contribution occurred in all patients. TII was achieved in 98% of cases, which compares favourably to a TII rate of 89% at the same centre during the period 2009 to 2011. CONCLUSIONS Diagnostic yield was 32.6% for IC and 39.2% when oesophago-gastro-duodenoscopy also occurred. A TII rate of 98% should be achievable in children. A change in management occurred in 45% and as a significant negative finding may be as important as a positive diagnosis for exclusion of suspected disorders, with consequent reassurance and change in management. Contribution to management was therefore identified in all cases.

Diagnostic Value of Fecal Calprotectin (S100 A8/A9) Test in Children with Chronic Abdominal Pain. Gastroenterol Res Pract 2016; 2016:8089217. [PMID: 27974886 PMCID: PMC5126428 DOI: 10.1155/2016/8089217] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/21/2016] [Revised: 09/28/2016] [Accepted: 10/19/2016] [Indexed: 12/22/2022] Open
Abstract
Objectives. The aim of the study was to establish whether fecal calprotectin concentration (FCC) may be useful in children with chronic abdominal pain to differentiate between inflammatory bowel disease (IBD), other inflammatory gastrointestinal disorders, and functional gastrointestinal disorders. Methods. The study included 163 patients (median age 13 years), who were assigned to four study groups: group 0 (control), 22 healthy children; group 1, 33 children with functional gastrointestinal disorders; group 2, 71 children with inflammatory gastrointestinal disorders other than IBD; group 3, 37 children with IBD. FCC was measured using ELISA assay. Results. In group 0 and group 1 FCCs were below 100 μg/g. Low FCCs were found in 91% of patients in group 2. In patients with IBD FCCs were markedly elevated with median value of 1191.5 μg/g. However, in children with inflammatory gastrointestinal disorders other than IBD and in children with IBD mean FCCs were significantly higher compared with the control group. Significant differences in FCCs were also found between group 1 and group 2, between group 1 and group 3, and between group 2 and group 3. Conclusion. FCC is the best parameter allowing for differentiation between IBD, other inflammatory gastrointestinal disorders, and functional gastrointestinal disorders. High FCC is associated with a high probability of IBD and/or other inflammatory gastrointestinal disorders, and it allows excluding functional gastrointestinal disorders.

Abstract
Inflammatory bowel disease (IBD) and irritable bowel syndrome share many symptoms. While irritable bowel syndrome is a functional bowel disorder for which no specific treatment is available, the range of effective therapies for IBD is evolving rapidly. Accurate diagnosis of IBD is therefore essential. Clinical assessment, together with various imaging modalities and endoscopy, has been the mainstay of diagnosis for many years. Fecal biomarkers of gastrointestinal inflammation have appeared in the past decade, of which calprotectin, a neutrophil cytosolic protein, has been studied the most. Crohn’s disease and ulcerative colitis are chronic remitting and relapsing diseases, and objective assessment of disease activity and response to treatment are important. This review focuses on the use of fecal calprotectin measurements in the diagnosis and monitoring of patients with IBD.

Andréasson K, Ohlsson B, Mandl T. Elevated levels of faecal calprotectin in primary Sjögren's syndrome is common and associated with concomitant organic gastrointestinal disease. Arthritis Res Ther 2016; 18:9.

Abstract
Background Primary Sjögren’s syndrome (pSS) is a systemic rheumatic disease in which gastrointestinal (GI) symptoms are common. Faecal calprotectin (FC) is a non-invasive biomarker that has been suggested to discriminate organic intestinal disease from functional disorders. The purpose of this study was to explore the usefulness of FC testing in patients with pSS. Methods In total, 56 consecutive patients with pSS and 29 healthy control subjects were included in this cross-sectional study. FC was measured with a commercially available enzyme-linked immunosorbent assay kit. GI symptoms were evaluated with the Rome III questionnaire and the Visual Analogue Scale for Irritable Bowel Syndrome. In patients with pSS, disease activity was estimated using the European League Against Rheumatism (EULAR) Sjögren’s Syndrome Disease Activity Index (ESSDAI), and patient-reported outcomes were evaluated with the EULAR Sjögren’s Syndrome Patient-Reported Index. Results Patients with pSS had higher levels of FC than healthy control subjects (median 54 μg/g, interquartile range [IQR 20–128]; vs. 20 μg/g [20–43]; p = 0.002). Concomitant organic GI disease was found in 14 patients with pSS and included inflammatory bowel disease (n = 3), colonic adenoma (n = 2) and GI lymphoma (n = 1). Patients with organic GI disease had higher FC levels than the other patients with pSS (median 274 μg/g [IQR 61–363] vs. median 34 μg/g [IQR 20–76]; p < 0.001). Although patients with pSS reported abdominal discomfort more frequently than healthy control subjects did, such symptoms were not associated with organic GI disease or elevated FC levels. FC correlated moderately with ESSDAI. Excluding patients with organic GI disease, we did not identify any significant association between ESSDAI and FC levels. Conclusions GI symptoms are frequent in pSS. Contrary to patient-reported outcomes, elevated FC levels in pSS indicate possible organic GI disease that warrants further investigation.

Abstract
BACKGROUND Chronic abdominal pain (CAP) is a common indication for gastroenterology referrals. More insidious causes of CAP isolated to the small bowel, such as malignancies and Crohn's disease, are rising in incidence and causing more gastroenterologists to evaluate their patients with video capsule endoscopy (VCE). However, the role of VCE in patients with CAP is still unclear. AIMS We assessed the efficacy of VCE in patients with CAP and whether it led to findings that contributed to disease management and meaningful interventions. METHODS This retrospective study evaluated 607 capsule endoscopy studies at an open referral endoscopy unit. Ninety of the studies were for CAP. These studies were compared to those performed for other indications to compare diagnostic yield. In addition, we investigated whether VCE led to an intervention that improved clinical outcomes. RESULTS Overall, the number of abnormal findings in CAP patients was significantly lower than VCE performed for other indications (24.4% vs 39.0%, respectively p = 0.009). When patients with CAP presented with other pertinent clinical findings (e.g. nausea, weight loss, anemia, history of in inflammatory bowel disease, etc.), the likelihood of an abnormal finding increased to a level that was not different from those who received VCE for other indications (27.1%, p = 0.10). The findings from VCE lead to changed management and improved outcomes in 16.2% of CAP patients with associated symptoms. However, the subgroup that benefited the most were those who had a prior history of Crohn's disease. Patients with CAP who did not have any associated symptoms continued to have a significantly lower abnormal finding rate compared to those who received VCE for other indications (19.4%, p = 0.03) and VCE rarely led to a change in management that would improve outcomes (5.6%). CONCLUSIONS VCE for CAP has a lower rate of abnormal findings than other indications. However, VCE is a useful diagnostic tool that can help provide a possible etiology of CAP in patients with associated symptoms. However, a change in management from VCE is likely to be limited to those with a history of Crohn's disease.

Abstract
Inflammatory bowel disease (IBD) is a chronic disease mostly involved with intestine with unknown etiology. Diagnosis, evaluation of severity, and prognosis are still present as challenges for physicians. An ideal biomarker with the characters such as simple, easy to perform, noninvasive or microinvasive, cheap, rapid, and reproducible is helpful for patients and clinicians. Currently biomarkers applied in clinic include CRP, ESR, pANCA, ASCA, and fecal calprotectin. However, they are far from ideal. Lots of studies are focused on seeking for ideal biomarker for IBD. Herein, the paper reviewed recent researches on biomarkers of IBD to get advances of biomarkers in inflammatory bowel disease.
