AbstractImmune response involving various immunoglobulin (Ig) isotypes and subtypes to microbiome is involved in the pathogenesis and disease activity of inflammatory bowel diseases (IBDs). To clarify the presence of Ig-coated bacteria in the intestine and its association with disease activity in ulcerative colitis (UC) and Crohn’s disease (CD), we extracted and classified Ig-coated bacteria from fecal samples of 42 patients with IBD and 12 healthy controls (HCs) using flow cytometry and 16S ribosomal RNA sequence analysis. The percentage of bacteria coated with IgA and IgM was higher in patients with IBD than in HCs, and IgG-coated bacteria were found only in patients with IBD. Moreover, the percentages of bacteria coated with IgG1, IgG2, IgG3, and IgM in UC samples and IgG3, IgG4, and IgM in CD samples were correlated with disease activities. The proportions of Bacteroides ovatus and Streptococcus increased during the active phase of CD. Hence, the detailed analysis of Ig-coated bacteria and Ig subtypes using flow cytometry could aid in developing useful indicators of disease activity and identifying more disease-related bacteria, which could become novel treatment targets for IBDs.

Circular RNAs reminiscent of viroids and the human hepatitis delta virus have been proposed as possible nonconventional pathogens responsible for Crohn's disease and ulcerative colitis, two inflammatory bowel diseases. Consequently, RNA was extracted from various areas of intestinal tissues from individuals with either Crohn's disease or ulcerative colitis as well as several appropriate control diseases, and analyzed by two-dimensional gel electrophoresis. No circular viroid-like RNAs (<1500 nucleotides) were detected, confirming a previous report that was limited to the investigation of small RNAs (<300 nucleotides). However, three small, unusually stable, linear RNAs were shown to be associated to both Crohn's disease and ulcerative colitis tissues: a specific 28S ribosomal RNA cleavage product characterized previously; a 5.8S ribosomal RNA conformer; and a fragment homologous to transcripts from DNA CpG islands. The two last RNAs were detected prior to visible morphological tissue alterations, suggesting that they are produced early during the inflammation and that they have value as molecular diagnostic tools for the inflammatory bowel diseases. The potential cellular mechanisms producing these RNAs and their involvement in inflammatory bowel disease are discussed. Key words: ribosomal RNA, inflammatory bowel diseases, human intestine, inflammation, viroids.

SummaryIn adults, inflammatory bowel disease (IBD) is associated with an increased risk of thromboembolic complications. The pathogenesis of IBD is not really clear and a high thrombin activity might contribute to disease progression. We wanted to see whether children with IBD have a higher thrombin generation (TG). Patients, material, methods: Plasma samples were collected of 20 patients with IBD and of 60 healthy controls (age range from 10 to 19). TG was measured by means of Calibrated automated thrombography (CAT). The disease activity was estimated, using the Pediatric Crohn‘s Disease Activity Index (PCDAI) for Crohn‘s disease and the Pediatric Ulcerative Colitis Disease Activity Index (PUCAI) for Ulcerative Colitis. In addition, we investigated F1+F2, TAT, TFPI and fibrinogen. Results: There was a significant increase of endogenous thrombin potential (ETP), lag time and time to peak in patients with IBD, while peak showed no difference to healthy controls. ETP and F1+F2 in children with IBD also showed a significant correlation with PCDAI (PUCAI) and fibrinogen. Conclusion: IBD in children is associated with high TG, but this seems to be caused mainly by the inflammatory process and not by any individual disposition.

The aim of the study was to analyze the differences in the activity of beta-glucuronidase and beta-glucosidase in stool specimens of children with Inflammatory Bowel Diseases (IBD) and healthy subjects. The disease activity was determined according to the PCDAI scale (Crohn disease) and Truelove-Witts scale (Ulcerative colitis). Enzyme activity was determined by spectrophotometry. There was a correlation between the level of beta - glucosidase activity in stool and patient's age in the group of healthy controls, but not in the IBD group. beta-glucosidase activity in IBD and healthy subjects stool specimens did not differ significantly. The activity of beta-glucuronidase in children with IBD was two times lower than in the healthy group and was correlated with age in children with IBD, but not in the group of healthy ones.

Leukocyte Imaging

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.

Nowadays there are certain difficulties in the early diagnosis of ulcerative colitis, proceeding with minimal intestinal symptoms. The etiology of the disease remains unclear to this day; there is no exact information about the prevalence of the disease due to the large number of latent forms and the low number of patients seeking medical help. This article presents the results of a retrospective analysis of the incidence of ulcerative colitis in the coloproctology department of the First Republic Clinical Hospital of Izhevsk. The study was conducted to assess the frequency of occurrence and determine the internal picture of ulcerative colitis. To achieve this goal, we selected 34 patients with ulcerative colitis. A statistical study was conducted on the following criteria: gender composition, age groups, forms of the disease, localization, complications, and main complaints. The length of hospital stay often was not more than 20 days. The literature on this pathology was also studied and presented in the form of a theoretical basis, which consisted of the determination and etiology of inflammatory bowel diseases. Due to the unknown etiology, insufficiently studied pathogenesis, difficult differential diagnosis with other intestinal diseases and insufficiently perfect treatment methods, there are a large number of unresolved problems in the field of ulcerative colitis. That is why, in this article we tried to reveal the problem of the features of the course and complex therapy of that disease in clinical practice.

Difficult Issue

Westernization and today’s changing life style is resulting in various health problems like Inflammatory Bowel diseases, which is a common entity encountered in surgical practise. Ulcerative colitis is the most common among them. Though it is believed to have auto immune and genetic origin, today’s life style, environment, diet and stress plays an important role in aetiology. The disease is prevalent in middle aged western and northern people characterised by abdominal pain with bloody diarrhoea, weight loss, anaemia and general debility. This condition has remissions and exacerbations. One should always keep in mind that inflammatory bowel diseases can have anorectal manifestations. Diagnosis is made on the basis of symptoms, stool exam. and endoscopy. Management is symptomatic i.e. antibiotics, anti-inflammatory, anti-spasmodic, multivitamins, immune suppression and if required admission, intravenous fluids. if no response colectomy. As such there is no satisfactory treatment till date, so it remains the difficult issue. Here we need to have an alternative, safe, convenient treatment. Ayurveda has an answer for such cases.

Inflammatory Bowel

Inflammatory bowel diseases such as ulcerative colitis (UC) may be complicated by several extraintestinal manifestations. These involve joints, skin, eyes and less commonly lungs and heart. Myocarditis may result from the toxic effect of drugs (ie, mesalazine) commonly used for the treatment of UC or due to infections (eg, Coxsackieviruses, enteroviruses, adenovirus). Here, we report a case of a 26-year old man affected by UC and complicated by two episodes of myocarditis. Both episodes occurred during two severe exacerbations of UC. However, in both cases the aetiology of myocarditis remains uncertain being ascribable to extraintestinal manifestation, drug toxicity or both.

Inflammatory Bowel

The potential of endoscopic evaluation in the management of inflammatory bowel diseases (IBD) has undoubtedly grown over the last few years. When dealing with IBD patients, histological remission (HR) is now considered a desirable target along with symptomatic and endoscopic remission, due to its association with better long-term outcomes. Consequently, the ability of endoscopic techniques to reflect microscopic findings in vivo without having to collect biopsies has become of upmost importance. In this context, a more accurate evaluation of inflammatory disease activity and the detection of dysplasia represent two mainstay targets for IBD endoscopists. New diagnostic technologies have been developed, such as dye-less chromoendoscopy, endomicroscopy, and molecular imaging, but their real incorporation in daily practice is not yet well defined. Although dye-chromoendoscopy is still recommended as the gold standard approach in dysplasia surveillance, recent research questioned the superiority of this technique over new advanced dye-less modalities [narrow band imaging (NBI), Fuji intelligent color enhancement (FICE), i-scan, blue light imaging (BLI) and linked color imaging (LCI)]. The endoscopic armamentarium might also be enriched by new video capsule endoscopy for monitoring disease activity, and high expectations are placed on the application of artificial intelligence (AI) systems to reduce operator-subjectivity and inter-observer variability. The goal of this review is to provide an updated insight on contemporary knowledge regarding new endoscopic techniques and devices, with special focus on their role in the assessment of disease activity and colorectal cancer surveillance.
