BACKGROUND: Iron deficiency anemia (IDA) is an often unrecognized and undertreated complication of ulcerative colitis (UC). We conducted the first nationwide study in the United States to evaluate the prevalence of testing for iron deficiency (ID) in anemic UC patients and determine the frequency of treatment with iron supplementation in patients with IDA. METHODS: Nationwide cohort of patients with newly diagnosed UC in the Veterans Affairs health care system was identified...

Despite advances in our understanding of the pathophysiology underlying inflammatory bowel disease, there remains a significant need for biomarkers that can differentiate between Crohn's disease and ulcerative colitis with high sensitivity and specificity, in a cost-efficient manner. As the focus on personalized approaches to the delivery of medical treatment increases, new biomarkers are being developed to predict an individual's response to therapy and their overall disease course. In this review, we will outline many of the existing and recently developed biomarkers, detailing their role in the assessment of patients with inflammatory bowel disease...

INTRODUCTION: Concurrent cytomegalovirus (CMV) in inflammatory bowel disease-related colitis is an important yet complex clinical scenario associated with high rates of colectomy and other morbidity. This review aimed to examine the literature to produce a comprehensive diagnostic and treatment algorithm for the management of CMV in patients with colitis. METHODS: A systematic literature review was conducted via PubMed/Medline databases until August 31, 2015, using multiple keywords in English language and where original data only presented...

BACKGROUND: Fecal high mobility group box 1 (HMGB1) has been suggested to be a novel noninvasive biomarker of gut inflammation. We aimed to assess the reliability of fecal HMGB1, compared with fecal calprotectin (FC), in detecting intestinal inflammation in pediatric and adult patients with inflammatory bowel disease (IBD) and to evaluate the accuracy of HMGB1 in identifying patients with IBD in clinical and endoscopic remission who still have histologic features of inflammation. METHODS: Stool samples from 85 children with IBD (49 Crohn's disease [CD] and 36 ulcerative colitis [UC] and 119 adults [57 Crohn's disease and 62 ulcerative colitis]) were analyzed for the study...

BACKGROUND: Data describing the incidence and the risk factors for surgical interventions in pediatric Crohn's disease (CD) is inconsistent. Our aim was to describe the rates of intestinal surgery and to identify associated risk factors in a large cohort of children with CD. METHODS: Medical charts of 482 children with CD from the Schneider Pediatric Inflammatory Bowel Disease cohort who were diagnosed between 1981 and 2013 were carefully reviewed retrospectively...

BACKGROUND: Inflammatory bowel diseases (IBD) including ulcerative colitis and Crohn's disease are diseases with impaired epithelial barrier function. We aimed to investigate whether mutated prostasin and thus, reduced colonic epithelial sodium channel activity predisposes to develop an experimentally dextran sodium sulfate (DSS)-induced colitis. METHODS: Wildtype, heterozygous (fr/+), and homozygous (fr/fr) prostasin-mutant rats were treated 7 days with DSS followed by 7 days of recovery and analyzed with respect to histology, clinicopathological parameters, inflammatory marker mRNA transcript expression, and sodium transporter protein expression...

BACKGROUND: Anemia is a common complication among patients with inflammatory bowel diseases (IBD) and is associated with high rates of IBD-related complications, resource utilization, and impaired quality of life. Despite practice guidelines for anemia in patients with IBD, gaps remain in the perceptions of anemia among health care providers. The aims of this study were to identify gaps in care and to develop a care pathway for anemia in patients with IBD. METHODS: The Crohn's & Colitis Foundation of America anemia care pathway was developed by a committee using principles of cognitive task analysis...

BACKGROUND: The potential need for an ostomy is a main concern for patients with inflammatory bowel disease. We performed this study to evaluate the impact of a long-term ostomy (≥6 mo duration) on the functional status and specific patient-reported outcomes in a population of patients with Crohn's disease (CD). METHODS: We performed a cross-sectional analysis within the Crohn's and Colitis Foundation of America Partners cohort. Bivariate analyses and logistic regression models were used to investigate associations between ostomy and various demographic, disease factors, and patient-reported outcomes for health-related quality of life...

BACKGROUND: The antioxidant transcription factor Nrf2 confers broad cytoprotection and has a dual role in tumorigenesis. Enhancing proteasome activity is one mechanism by which Nrf2 can promote cancer development, e.g., colorectal cancer. This study investigated whether this potential oncogenic effect of Nrf2 emerges already from the epithelial adaptation to persistent oxidative stress during inflammatory bowel disease (IBD). METHODS: Reactive oxygen species (ROS)-producing inflammatory myeloid cells (IMCs) from colon tissue of patients with IBD were cocultured with human NCM460 colonocytes...

BACKGROUND: Recently, long noncoding RNA (lncRNA) H19 has been reported to be related with VDR signaling and the development of inflammatory diseases including osteoarthritis. The aim of this study was to investigate the correlation between the expression level of H19 and VDR in ulcerative colitis (UC) tissues and to investigate the effect of H19 overexpression on intestinal epithelial barrier function. METHODS: The expression level of H19, miR-675-5p, and VDR in UC tissues and paired normal tissues collected from 12 patients with UC was investigated by quantitative real-time polymerase chain reaction...

BACKGROUND: Inflammatory bowel disease (IBD) is characterized by a chronic inflammation of the gut, partly driven by defects in the expression and function of pattern recognition receptors, including the IFI16 protein. Because this protein is a target for autoantibodies and its aberrant expression was reported in colonic mucosa from active patients with ulcerative colitis, we studied its expression and specific seroresponse in patients with IBD before and after infliximab (IFX) therapy...

Investigator-initiated randomized clinical trials are the backbone of academic clinical research. Investigator-initiated trials (IITs) complement the large clinical studies sponsored by industry and address questions, which are usually not the main focus of a commercially directed research but have the purpose to confirm, improve, or refute clinically important questions with regard to diagnostic and therapeutic approaches in patient care. The aim of this review is to illustrate the necessary steps to start and complete an IIT in the field of inflammatory bowel diseases in the United States...

The relevance of azathioprine and 6-mercaptopurine therapy in inflammatory bowel disease, Crohn's disease, and ulcerative colitis, has been challenged in recent publications. In this article, a panel of experts gives advice, based on the relevant literature, on indications and practical use of azathioprine/6-mercaptopurine, prevention, and management of drug adverse reactions and special situations such as vaccination, pregnancy, and lactation.

BACKGROUND: Exclusive enteral nutrition (EEN) is a first-line therapy in pediatric Crohn's disease (CD) thought to induce remission through changes in the gut microbiome. With microbiome assessment largely focused on microbial taxonomy and diversity, it remains unclear to what extent EEN induces functional changes that thereby contribute to its therapeutic effect. METHODS: Fecal samples were collected from 15 pediatric CD patients prior to and after EEN treatment, as well as from 5 healthy controls...

BACKGROUND: Statins have antiinflammatory effects at the cardiovascular level because of inhibition of prenylation, which also probably underlies their therapeutic effects in preclinical models of inflammatory bowel disease. Another inhibitor of prenylation, namely alendronate, reduces colitis in rodents. In this study, we aim to explore the therapeutic potential of second-generation, nitrogen-containing bisphosphonates in 3 preclinical models of colitis. METHODS: The trinitrobenzenesulfonic acid and dextran sulfate sodium models of rat colitis and the adoptive lymphocyte transfer model of colitis in mice were used...
