Eosinophilic colitis (EC) is a common cause of haematochezia in infants and young children. The exact pathomechanism is not understood, and the diagnosis is challenging. The role of microRNAs as key class of regulators of mRNA expression and translation in patients with EC has not been explored. Therefore, the aim of the present study was to explore the miRNA profile in EC with respect to eosinophilic inflammation. Patients enrolled in the study (n = 10) had persistent rectal bleeding, and did not respond to elimination dietary treatment...

BACKGROUND: Indigo naturalis (IND) is an herbal medicine that has been used as an anti-inflammatory agent to treat diseases including dermatitis and inflammatory bowel disease in China. However, the mechanism by which IND exerts its immunomodulatory effect is not well understood. METHODS: A murine model of dermatitis and inflammatory bowel disease, both induced by oxazolone (OXA), was treated with IND. The severity of dermatitis was evaluated based on ear thickness measurements and histological scoring...

We present the case of a twenty two year old Caucasian male with ulcerative colitis on mesalamine who presented with dry cough, fever, malaise and dyspnea on exertion. He had peripheral eosinophilia and apical ground-glass opacities on computed tomography of the chest. He had no new exposures and his infectious workup was non diagnostic. Bronchoalveolar lavage showed eosinophilia raising the suspicion of mesalamine induced eosinophilic pneumonia. His symptoms improved after discontinuing mesalamine with a tapered dose of steroids...

INTRODUCTION: Eosinophilic colitis, which is a rare form of eosinophilic gastrointestinal diseases, occurs as primary and secondary allergic eosinophilic colitis of the gastrointestinal tract infection, inflammatory bowel disease, celiac disease, and vasculitis. The diagnosis is based on a significant amount of eosinophils in the inflammatory infiltrate of the colon wall. AIM: To analyze the clinical picture taking into account comorbidities and endoscopic picture in children with eosinophilic colitis...

The parasite Entamoeba histolytica is a cause of diarrhea in infants in low-income countries. Previously, it was shown that tumor necrosis factor alpha (TNF-α) production was associated with increased risk of E. histolytica diarrhea in children. Interleukin-25 (IL-25) is a cytokine that is produced by intestinal epithelial cells that has a role in maintenance of gut barrier function and inhibition of TNF-α production. IL-25 expression was decreased in humans and in the mouse model of amebic colitis. Repletion of IL-25 blocked E...

Food allergy is a common health problem worldwide, with increasing prevalence during recent decades. The only approved treatments for food allergy are food avoidance and administration of emergency medications in case of accidental exposure, which negatively affects patients' quality of life, so new treatments are highly desirable. Different food immunotherapy modalities have recently been used, with variable success rates in the induction of desensitization and tolerance, and different numbers and types of adverse reactions...

Clostridium difficile is the leading cause of healthcare-associated infections in the United States. Clinically, C. difficile-associated disease can present as asymptomatic colonization, self-limited diarrheal illness or severe colitis (that may result in death). This variability in disease course and outcomes suggests that host factors play an important role as key determinants of disease severity. Currently, there are several scoring indices to estimate severity of C. difficile-associated disease. Leukocytosis and renal failure are considered to be the most important predictors of C...

BACKGROUND: Mucositis is one of the most relevant gastrointestinal inflammatory conditions in humans, generated by the use of chemotherapy drugs, such as 5-fluoracil (5-FU). 5-FU-induced mucositis affects 80% of patients undergoing oncological treatment causing mucosal gut dysfunctions and great discomfort. As current therapy drugs presents limitations in alleviating mucositis symptoms, alternative strategies are being pursued. Recent studies have shown that the antimicrobial pancreatitis-associated protein (PAP) has a protective role in intestinal inflammatory processes...

Basal plasmacytosis is an early-onset and highly predictive feature of inflammatory bowel disease (IBD), but may have several restrictions in routine histology. Considering evidences about cooperation between eosinophils and plasma cells in IBD pathogenesis, we investigated immunostain of these two cells as a marker of disease. 343 samplings from 83 patients (52 IBD, 31 non-IBD colitis) were evaluated. The sections were stained with monoclonal antibodies against plasma cells (CD138 and MUM1), and eosinophils (CD193)...

Inflammatory bowel disease results from chronic dysregulation of the mucosal immune system and aberrant activation of both the innate and adaptive immune responses. IL-19 is a member of the IL-10 family, and IL-10 plays an important role in inflammatory bowel disease. We have previously shown that IL-19 knockout mice are more susceptible to innate-mediated colitis. Next, we ask whether IL-19 contributes to T cells-mediated colitis. Here, we investigated the role of IL-19 in a mouse model of Th2 cell-mediated colitis...

BACKGROUND: Recent immunologic data implicates involvement of mucosal immune cells of the intestine like eosinophils and mast cells to be functionally involved in the pathogenesis of UC. Mast cell activation is followed by increased secretion and elevated tissue concentration of histamine. Inhibition of mucosal histamine release in colon may be an effective therapeutic approach to treat UC. Some studies report that intestinal inflammation associated with acute and chronic colitis has been ameliorated by fexofenadine in mice...

The normal content of eosinophils in the adult colon and the criteria for the histopathologic diagnosis of eosinophilic colitis remain undefined. This study aimed at: (1) establishing the numbers of eosinophils in the normal adult colon; and (2) proposing a clinicopathologic framework for the diagnosis of primary colonic eosinophilia and eosinophilic colitis. To accomplish these goals, we counted the eosinophils in the right, transverse, and left colon of 159 adults with normal colonic histology. Using a database of 1...

Terminal ileitis (TI) is an inflammatory condition of the terminal portion of the ileum that may occur acutely with right lower quadrant pain followed or not by diarrhea, or exhibit chronic obstructive symptoms and bleeding and normally it is associated to Crohn's disease (CD) although it may be associated to other different conditions. This review intended to contribute to a better understanding of TI in order to help in the diagnosis, medical approach and patient care. This work was performed on a survey of articles collected in different databases and a retrospective search was carried out to identify relevant studies in the field...

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...

Helminthic therapy of immune-mediated diseases has gained attention in recent years, but we know little of how helminths modulate human immunity. In this study, we investigated how self-infection with Trichuris (T.) trichiura in an adult man without intestinal disease affected mucosal and systemic immunity. Colonic mucosal biopsies were obtained at baseline, during T. trichiura infection, and after its clearance following mebendazole treatment. Unexpectedly, the volunteer experienced a Campylobacter colitis following T...

OBJECTIVES: Endoscopic remission in ulcerative colitis (UC) is associated with improved clinical outcomes. We assessed whether histological remission predicts clinical outcomes, estimated the magnitude of effect, and determined whether histological remission provides additional prognostic utility beyond clinical or endoscopic remission. METHODS: Bibliographic databases were searched for studies in inflammatory bowel disease providing baseline histological status and relation to an outcome of clinical relapse or exacerbation...

Proinflammatory cytokines are thought to modulate pathogeneses of various inflammatory bowel diseases (IBDs). Thymic stromal lymphopoietin (TSLP), which has been studied in various allergic diseases such as asthma, atopic dermatitis (AD) and eosinophilic esophagitis (EoE), has been less considered to be involved in IBDs. However, mucosal dendritic cells (DCs) induced by various cytokines including TSLP were reported to cause polarization of T cell toward Th2 response, the differentiation of regulatory T-cell (Treg), and secretion of IgA by B cells...

Calprotectin is a heterodimeric protein which belongs to the calcium-binding protein S100 family. Calprotectin is released by leukocytes at the site of inflammation and it can be detected in the feces where it remains stable for about a week. Hence, increased fecal calprotectin (FC) levels are found in several inflammatory conditions, mainly the inflammatory bowel diseases (IBD). In the setting of pediatric gastroenterology, the importance of FC has increased over time. This review aims to summarize the most recent findings concerning the role of FC in the algorithm of different inflammatory and non-inflammatory conditions among pediatric patients...
