Several radiological and endoscopic techniques are now available for the study of inflammatory bowel diseases. In everyday practice, the choice of the technique to be used depends upon its availability and a careful evaluation of diagnostic accuracy, clinical usefulness, safety, and cost. The recent development of innovative and noninvasive imaging techniques has led to a new and exciting area in the exploration of the gastrointestinal tract, especially in Crohn’s disease patients by using ultrasound with oral or intravenous contrast.

Introduction: Epitheloid granulomas are one of the best histological criteria for distinguishing Crohn’s disease from other inflammatory bowel diseases. However, the role of granuloma in the pathogenesis and clinical characteristics of Crohn’s disease is unclear. Aim: The aim of the present study was to evaluate the frequency of granulomas and their association with clinical characteristics using the database of the Hungarian Pediatric Inflammatory Bowel Disease Registry. Method: Three hundred and sixty-eight children with Crohn’s disease were registered between January 1st, 2007 and December 31st, 2010. Results: The frequency of granulomas was 31.4% (111/353) at diagnosis. Isolated granuloma in the upper gastrointestinal tract was detected in 2.5% of patients, while those in the terminal ileum was found in 5% of patients. There was no difference in location, behavior and disease activity indexes between patients with and without granulomas. Need for immunomodulators and biological therapy was similar in the two groups in the first year of diagnosis. Conclusions: The frequency of granulomas in this cohort was comparable to the frequency reported in other studies. Interestingly, granulomas in the terminal ileum or upper gastrointestinal tract contributed to the diagnosis of Crohn’s disease in one of 13 children. These data indicate that multiple biopsies from multiple sites are essential for the diagnosis of pediatric Crohn’s disease. Orv. Hetil., 154 (43), 1702–1708.

Inflammatory bowel diseases (IBD), which is a term for two conditions (ulcerative colitis and Crohn’s disease), are chronic inflammatory diseases of the gastrointestinal tract that are the subject of many studies and much discussion around the world. The global prevalence of IBD is 20.4 per 100 thousand for ulcerative colitis and 3.7 per 100 thousand for Crohn’s disease. Every year the number of patients is increasing, which may indicate improvement in diagnosis of IBD, but at the same time demonstrates certain disadvantages and difficulties in the diagnosis and treatment of this group of patients. However, despite the fact that IBD has been exercising the minds of scientists around the world for many decades, many issues of diagnosis and treatment of this pathology appear relevant. Due to the paucisymptomatic condition of patients at early stages and the similarity of its symptoms with other gastroenterological diseases, the diagnosis of IBD involves certain difficulties in many cases. Advanced forms of the disease, as well as complications of IBD, result from late diagnosis. Endoscopic ultrasound (EUS, endo-ultrasound), which includes endoscopic and ultrasound examinations, is a modern imaging technique for the diagnosis of gastrointestinal diseases. The article discusses various international and Russian studies on the use of EUS in various pathologies of the gastrointestinal tract. Despite the absence of EUS in the formal guidelines for IBD, the technique appears promising for diagnosis, differential diagnosis of ulcerative colitis and Crohn’s disease, as well as complications of these diseases, such as primary sclerosing cholangitis, chronic and autoimmune pancreatitis, autoimmune hepatitis, pancreatic cancer, etc.

Crohn's disease (CD), along with ulcerative colitis, is one of the predominant nosological forms of inflammatory bowel diseases. In CD, any part of the gastrointestinal tract can be affected; however, the process is commonly associated with terminal ileum or colon involvement. CD cases with isolated or mixed involvement of upper gastrointestinal tract (esophagus, stomach, and duodenum) are rare and least studied types of the disease. In isolated stomach involvement, the complaints are non-specific and include epigastric pain, gastric dyspepsia, early satiety, decreased appetite, and nausea. Isolated CD of upper gastrointestinal tract can be diagnosed after comprehensive work-up and always requires a high diagnostic level, including clinical, endoscopic and morphological one. We present a clinical case of CD with isolated stomach involvement in a 62-year-old woman. The diagnosis was confirmed by the histopathological findings of an epithelioid cell granuloma in the gastric antrum. Treatment with systemic corticosteroids reduced the disease clinical activity and improved the histological characteristics of the gastric biopsy sampled obtained by endoscopy. In this clinical case, there were specific macroscopic gastric lesions found at endoscopy in CD patients with upper gastrointestinal tract involvement, which is characterized by thickened longitudinal folding and linear grooves. This type of lesion has been described in the literature as “bamboo joint-like appearance”.Conclusion: Comprehensive assessment of clinical manifestations, endoscopic and histopathological specific features is crucial for the timely diagnosis and treatment of inflammatory bowel diseases.

A prospective study was initiated to compare the clinically proven results concerning localization/extent and activity of inflammatory bowel diseases with those of 111ln-oxine leukocyte imaging. All patients studied were completely examined with barium enema x-ray, clinical and laboratory investigations, and endoscopy with histopathology. A total of 31 leukocyte scans were performed in 15 patients (12 with Crohn’s disease, 3 with ulcerative colitis). The scans were graded by comparing the cell uptake of a lesion (when present) and a bone marrow area providing a count ratio (CR). The inflammatory lesions were correctly localized on 26 leukocyte scans, and in 21 scans the scintigraphically estimated extent of disease was identical to endoscopy. In 5 cases the disease extent was underestimated, 4 scans in patients with relapse of Crohn’s disease were falsely negative, and in one patient with remission truly negative. The scintigraphically assessed disease activity was also in a good agreement with clinical disease activity based on histopathology in all cases. We conclude that leukocyte imaging provides valuable information about localization and activity of inflammatory bowel disease.

AbstractEpigenetics has become a promising field for finding new biomarkers and improving diagnosis, prognosis, and drug response in inflammatory bowel disease. The number of people suffering from inflammatory bowel diseases, especially Crohn's disease, has increased remarkably. Crohn's disease is assumed to be the result of a complex interplay between genetic susceptibility, environmental factors, and altered intestinal microbiota, leading to dysregulation of the innate and adaptive immune response. While many genetic variants have been identified to be associated with Crohn's disease, less is known about the influence of epigenetics in the pathogenesis of this disease. In this review, we provide an overview of current epigenetic studies in Crohn's disease. In particular, we enable a deeper insight into applied bioanalytical and computational tools, as well as a comprehensive update toward the cell-specific evaluation of DNA methylation and histone modifications.

And Behavior

Inflammatory bowel diseases (IBD) are characterized by chronic inflammation of the intestinal tract associated with an imbalance of the intestinal microbiota. Crohn’s disease (CD) and ulcerative colitis (UC) are the most widely known types of IBD and have been the focus of attention due to their increasing incidence. Recent studies have pointed out genes associated with IBD susceptibility that, together with environment factors, may contribute to the outcome of the disease. In ulcerative colitis, there are several therapies available, depending on the stage of the disease. Aminosalicylates, corticosteroids, and cyclosporine are used to treat mild, moderate, and severe disease, respectively. In Crohn’s disease, drug choices are dependent on both location and behavior of the disease. Nowadays, advances in treatments for IBD have included biological therapies, based mainly on monoclonal antibodies or fusion proteins, such as anti-TNF drugs. Notwithstanding the high cost involved, these biological therapies show a high index of remission, enabling a significant reduction in cases of surgery and hospitalization. Furthermore, migration inhibitors and new cytokine blockers are also a promising alternative for treating patients with IBD. In this review, an analysis of literature data on biological treatments for IBD is approached, with the main focus on therapies based on emerging recombinant biomolecules.

AbstractOne of the elements of treatment considering inflammatory bowel diseases is nutritional therapy. The duration of the above-mentioned depends on the prevalence of such symptoms as fever, bowel move-ments, length of the functioning gastrointestinal tract, stoma and intestinal fistula presence. Nutritional therapy is an essential element of successful treatment alongside pharmacological, surgical, and biological therapy, as well as other methods. Crohn's disease and ulcerative colitis considered as chronic diseases, lead towards physical and biopsychosocial disability, being responsible for the reduction in the quality of life.was to determine the quality of life after surgical procedures in case of patients diagnosed with Crohn's disease and ulcerative colitis, subjected to natural and parenteral nutrition.The study group comprised 52 patients from the Department of Gastroen-terology, Military Medical Institute, and Department of Surgery and Clinical Nutrition, Clinical Hospital in Warsaw. The study was performed between October, 2011 and April, 2012. The World Health Organization Quality of Life Instrument - Bref (WHOQOL-BREF) questionnaire was used to deter-mine the patients’ quality of life.A lower quality of life was observed in case of patients subjected to parenteral nutrition, poor education, disease symptoms exacerbation, in the majority-rural inhabitants. The quality of life does not depend on gender, type of disease, family status, and additional medical care.

Background: Inflammatory bowel diseases are strongly associated with colorectal cancer. In addition, a few cases reported with gastric and small bowel adenocarcinoma in gastroduodenal Crohn’s disease. Case report: We reported a case of a 47-Year-old female, who was referred to our surgical department and after a routine gastroscopy which revealed a lesion. Biopsy confirmed gastric well-differentiated adenocarcinoma of limited gastric Crohn’s disease, for a patient on regular anti Crohn’s medication. The patient underwent varying laparoscopic distal gastrectomy. She received adjuvant chemotherapy treatment and thereafter, she was cancer free within the period of 3- years of regular follow up. Conclusion: The only way to diagnose such lesions of a rare case of gastric cancer in a patient with Crohn’s disease is to regularly carry out upper gastrointestinal examinations.

AbstractGastrointestinal fibrosis is a state of accumulated biological entropy caused by a dysregulated tissue repair response. Acute or chronic inflammation in the gastrointestinal tract, including inflammatory bowel disease, particularly Crohn’s disease, induces fibrosis and strictures, which often require surgical or endoscopic intervention. Recent technical advances in endoscopic surgical techniques raise the possibility of gastrointestinal stricture after an extended resection. Compared to recent progress in controlling inflammation, our understanding of the pathogenesis of gastrointestinal fibrosis is limited, which requires the development of prevention and treatment strategies. Here, we focus on gastrointestinal fibrosis in Crohn’s disease and post-endoscopic submucosal dissection (ESD) stricture, and we review the relevant literature.

Disease Analysis

Inflammatory bowel diseases (IBD) include Crohn’s Disease and Ulcerative Colitis (1). We mined published microarray data to understand how gene expression in the hematopoietic compartment of patients with Crohn’s Disease is most different from that of healthy controls (2-4). Across two datasets (2, 3), we found that BAFF, also known as the B-lymphocyte stimulator (BLyS), encoded by the gene TNFSF13B (5), was differentially expressed in the blood of patients with Crohn’s Disease . Analysis of a third dataset (4) revealed that BAFF was among the genes most differentially expressed in monocyte-derived macrophages from patients with Crohn’s Disease. Serum BAFF, fecal BAFF, and BAFF expression in the intestinal mucosa has been demonstrated to be increased in patients with IBD (6, 7). We show here that expression of BAFF in the peripheral blood of patients with Crohn’s Disease is also increased.
