Cytomegalovirus (CMV) infects approximately 40% of adults in France and persists lifelong as a latent agent in different organs, including gut. A close relationship is observed between inflammation that favors viral expression and viral replication that exacerbates inflammation. In this context, CMV colitis may impact the prognosis of patients suffering from inflammatory bowel diseases (IBDs), and notably those with ulcerative colitis (UC). In UC, the mucosal inflammation and T helper cell (TH) 2 cytokines, together with immunomodulatory drugs used for controlling flare-ups, favor viral reactivation within the gut, which, in turn, increases mucosal inflammation, impairs corticoid and immunosuppressor efficacy (the probability of steroid resistance is multiplied by more than 20 in the case of CMV colitis), and enhances the risk for colectomy. This review emphasizes the virological tools that are recommended for exploring CMV colitis during inflammatory bowel diseases (IBD) and underlines the interest of using ganciclovir for treating flare-ups associated to CMV colitis in UC patients.

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 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.

Innate immunity prevents pathogens from entering and spreading within the body. This function is especially important in the gastrointestinal tract and skin, as these organs have a large surface contact area with the outside environment. In the intestine, luminal commensal bacteria are necessary for adequate food digestion and play a crucial role in tolerance to benign antigens. Immune system damage can create an intestinal inflammatory response, leading to chronic disease including inflammatory bowel diseases (IBD). Ulcerative colitis (UC) is an IBD of unknown etiology with increasing worldwide prevalence. In the intestinal mucosa of UC patients, there is an imbalance in the IL-33/ST2 axis, an important modulator of the innate immune response. This paper reviews the role of the IL-33/ST2 system in innate immunity of the intestinal mucosa and its importance in inflammatory bowel diseases, especially ulcerative colitis.

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.

Pathology of the liver and gallbladder is one of the extra-intestinal manifestations of inflammatory bowel diseases (IBD). Targeted examination indicates clinical, laboratory, and structural changes in the liver and gallbladder in 30% of patients with IBD. However, information about the state of the hepatobiliary zone in comparison with the IBD phenotype, the features of the course, and the nature of therapy are few, and their results are contradictory. The aim − to study the frequency of occurrence, to analyze the structural and functional features of the liver and gallbladder in relation to the phenotype, clinical and endoscopic activity of the process, the nature of the course, and the effectiveness of IBD therapy. Material and methods. A simple, open, single-stage, non-randomized study involved 157 patients with ulcerative colitis (UC) and 37 patients with Crohn's disease (CD) who were treated in the Gastroenterology Department of the City Clinical Hospital No. 5 in Saratov in the period of 2016−2019. Complex clinical, biochemical, and instrumental studies were performed (ultrasound examination of the abdominal organs, fibrogastroduodenoscopy and colonoscopy, general morphological examination of colonobioptates). Results. Non-alcoholic fatty liver disease (NAFLD) was verified in 10.8% of patients with UC (3.8% had non-alcoholic steаthohepatitis (NASH), 7% − liver steatosis) and in 27% of patients with CD (NASH – 5.4% of cases, liver steatosis – 21.6%). Dysfunctional disorders and structural changes of the gallbladder were detected in 14.3% of patients with UC and 20.8% with CD. Of these, cholelithiasis was found in 9.5% of patients with UC and 10.8% with CD. When analyzing the association of risk factors for hepatobiliary pathology with a variant of IBD, NAFLD was associated with the type of IBD course (recurrent course for CD), localization of the process (in UC – with left-sided colitis, in CD – with terminal ileitis), an operational history on the intestine in CD, the duration of CD for more than five years, overweight in UC, and the effects of basic therapy (steroid resistance). The pathology of the gallbladder is associated with the duration of IBD for more than three years, the continuous course of UC, and surgical interventions on the intestine in CD. When analyzing laboratory and structural markers of steatosis, it was noted that high values of the steatosis index prevailed in UC (according to J.H. Lee). Abdominal ultrasound revealed mild (41% in UC, 40% in CD) and moderate (47.1% in UC, 50% in CD) liver steatosis more often. When analyzing the clinical features of the hepatobiliary system, it was found that liver pathology was detected by instrumental and laboratory criteria, and gallbladder pathology was characterized clinically by symptoms of biliary dyspepsia in the absence of biliary colic attacks. Conclusion. The features of liver and gallbladder pathology identified during the study can be used to optimize the management of patients with IBD

Background Determination of fecal calprotectin can provide an important guidance for the physician, also in primary care, in the differential diagnosis of gastrointestinal disorders, meanly between inflammatory bowel diseases and irritable bowel syndrome. Objectives The aims of the present study were to prospectively investigate, in Brazilian adults with gastrointestinal complaints, the value of fecal calprotectin as a biomarker for the differential diagnosis between functional and organic disorders and to correlate the concentrations with the activity of inflammatory bowel diseases. Methods The study included consecutive patients who had gastrointestinal complaints in which the measurement levels of fecal calprotectin were recommended. Fecal calprotectin was measured using a Bühlmann (Basel, Switzerland) ELISA kit Results A total of 279 patients were included in the study, with median age of 39 years (range, 18 to 78 years). After clinical and laboratorial evaluation and considering the final diagnosis, patients were allocated into the following groups: a) Irritable Bowel Syndrome: 154 patients (102 female and 52 male subjects). b) Inflammatory Bowel Diseases group: 112 patients; 73 with Crohn’s disease; 38 female and 35 male patients; 52.1% (38/73) presented active disease, and 47.9% (35/73) had disease in remission and 39 patients with ulcerative colitis;19 female and 20 male patients; 48.7% (19/39) classified with active disease and 49.3% (20/39) with disease in remission. A significant difference (P<0.001) was observed between the median value of fecal calprotectin in Irritable Bowel Syndrome group that was 50.5 µg/g (IQR=16 - 294 µg/g); 405 µg/g (IQR=29 - 1980 µg/g) in Crohn’s disease patients and 457 µg/g (IQR=25 - 1430 µg/g) in ulcerative colitis patients. No difference was observed between the values found in the patients with Crohn’s disease and ulcerative colitis. Levels of fecal calprotectin were significantly lower in patients with inflammatory bowel diseases in remission when compared with active disease (P<0.001). Conclusions The present study showed that the determination of fecal calprotectin assists to differentiate between active and inactive inflammatory bowel diseases and between inflammatory bowel diseases and irritable bowel syndrome.

Inflammatory bowel diseases are an urgent public health problem and are often complicated by the development of anemic syndrome. Significant progress has been made in the treatment of ulcerative colitis and Crohn's disease, but the correction of associated anemia in most cases remains insufficient. This article describes in detail the pathogenetic mechanisms of the formation of anemic syndrome in inflammatory bowel diseases, as well as possible ways to correct this condition.

The aim of the present paper is to review the effects of non-digestible oligosaccharides (NDO) on immunity, focusing on their microbiota-independent mechanisms of action, as well as to explore their potential beneficial role in inflammatory bowel diseases (IBD). IBD are chronic, inflammatory conditions of the gastrointestinal tract. Individuals with IBD have an aberrant immune response to commensal microbiota, resulting in extensive mucosal inflammation and increased intestinal permeability. NDO are prebiotic fibres well known for their role in supporting intestinal health through modulation of the gut microbiota. NDO reach the colon intact and are fermented by commensal bacteria, resulting in the production of SCFA with immunomodulatory properties. In disease states characterised by increased gut permeability, prebiotics may also bypass the gut barrier and directly interact with intestinal and systemic immune cells, as demonstrated in patients with IBD and in infants with an immature gut. In vitro models show that fructooligosaccharides, inulin and galactooligosaccharides exert microbiota-independent effects on immunity by binding to toll-like receptors on monocytes, macrophages and intestinal epithelial cells and by modulating cytokine production and immune cell maturation. Moreover, animal models and human supplementation studies demonstrate that some prebiotics, including inulin and lactulose, might reduce intestinal inflammation and IBD symptoms. Although there are convincing preliminary data to support NDO as immunomodulators in the management of IBD, their mechanisms of action are still unclear and larger standardised studies need to be performed using a wider range of prebiotics.
