Objectives: Members of the S100 protein family, S100A8, S100A9 and their heterodimer complex known as calprotectin are thought to be involved not only in inflammatory pathways but also in tumorigenesis and cancer progression. Therefore, they have been widely studied in various types of cancer; however, there is limited knowledge about their role in bladder cancer. In this study, our aim was to determine the levels of S100A8 and S100A9 in the sera, and calprotectin levels in the sera and urines of bladder cancer patients and compare it to urinary BTA, a tumor marker that can be used in the diagnosis of bladder cancer.
Materials And Methods: The study was comprised of two major groups: 52 healthy controls and 82 patients with bladder cancer. The patient group was also divided into subgroups according to tumor stage and grade. Urine BTA levels, serum S100A8 and S100A9 levels, and serum and urine calprotectin levels in healthy controls and patients were determined using commercially available ELISA kits.
Results: While serum S100A8 and S100A9 levels did not differ between the controls and patients significantly, serum and urine calprotectin levels and urine BTA levels were significantly elevated in patients compared to controls. Serum calprotectin or urine BTA levels did not differ significantly among the patient subgroups. However, urine calprotectin levels were significantly elevated in muscle-invasive tumors (T2-4) compared to lower stages (Ta and T1).
Conclusions: Urine calprotectin levels can be used in the diagnosis and staging of bladder cancer as a marker for muscle invasion.

Body Mass Index Did Not Impact Efficacy and Safety of Etrasimod: A Post Hoc Analysis of the ELEVATE UC Clinical Program.
Am J Gastroenterol

Division of Gastroenterology and Hepatology, Department of Medicine, University of Calgary, Calgary, AB, Canada.
Objective: High body mass index (BMI) may reduce ulcerative colitis (UC) treatment efficacy. Etrasimod is an oral, once-daily (QD), selective sphingosine 1-phosphate (S1P)1,4,5 receptor modulator for the treatment of moderately to severely active UC. This post hoc analysis assessed treatment outcomes according to BMI in ELEVATE UC 52 and ELEVATE UC 12.

Background And Aims: Prior studies indicate that serum calprotectin (SC) and plasma calprotectin (PC) can be used as biomarkers in Crohn's disease (CD). The aim of this study was to investigate the diagnostic accuracy of SC and PC in patients with a clinical suspicion of CD.
Method: This biobank study included patients from a prospective, blinded, multicenter study examining minimally invasive modalities for diagnosing CD.
Maintenance-phase serum anti-TNF levels are not associated with mucosal healing in pediatric Crohn's disease.

Objectives: Mucosal healing (MH) is a key therapeutic target in Crohn's disease (CD) and is associated with improved outcomes. While adult studies indicate a positive correlation between serum anti-tumor necrosis factor (TNF) levels and MH, data in pediatric patients is limited. We aimed to define the association of serum anti-TNF levels with MH in pediatric patients with CD during maintenance therapy.

Purpose: The performance of endoscopic evaluation of ulcerative colitis (UC) using conventional scoring, including Mayo endoscopic subscore (MES) and ulcerative colitis endoscopic index of severity (UCEIS), is not satisfactory. Recently, the usefulness of novel image-enhanced endoscopy (IEE) such as texture and color enhancement imaging (TXI) and red dichromatic imaging (RDI) has been reported in the endoscopic evaluation of UC. We evaluated the performance of IEEs in UC, particularly focusing on the correlation with MES and UCEIS, and prediction of relapse.

Objectives: Faecal microbiota transplantation (FMT) is an established treatment for recurrent Clostridioides difficile infection (R-CDI). This study aimed to identify calprotectin and microbiome characteristics as potential biomarkers of FMT success.
Methods: We conducted a prospective study of patients who underwent oral FMT (single dose of 4-5 capsules) for R-CDI (January 2018 to December 2022).
