Inflammatory bowel disease (IBD) comprises ulcerative colitis (UC) and Crohn’s disease (CD). IBD etiopathology is multifactorial and involves alteration of immune cells and chronic activation of the inflammatory cascade against yet unknown environmental factors that trigger the disease. IBD therapy aims at improving the quality of life and reducing the risk of disease-related complications to avoid the need for surgery. There is no specific cure for IBDs, and the focus of therapy is supportive measures and use of anti-inflammatory and immunosuppressive drugs. Glucocorticoids (GCs) are powerful anti-inflammatory and immunomodulatory agents used to treat many acute and chronic inflammatory diseases. GCs remain basic treatment for moderate-to-severe IBD, but their use is limited by several important adverse drug effects. Topical administration of a second-generation of GCs, such as budesonide and beclomethasone dipropionate (BDP), represents a valid alternative to use of older, systemic GCs. Administration of second-generation GCs shows promisingly high topical activity and less systemic toxicity, but maintenance therapy with these new GCs in IBD patients is associated with multiple adverse effects. In this review, we make a comparative analysis of the efficacy of first-generation and second-generation GCs in IBD treatment. Unraveling GC biology at the molecular level to uncouple their clinical benefits from detrimental effects is important. One approach is to consider new GC mediators, such as glucocorticoid-induced leucine zipper, which may have similar anti-inflammatory properties, but avoids the side effects of GCs. This in-depth analysis can help to improve the development and the clinical outcomes of GC therapies in IBD.

Inflammatory bowel disease (IBD) is one of the most common causes of chronic clinical signs from the gastrointestinal tract, associated with histological evidence of inflammation in the lamina propria of the small and/or large intestine in cats. The underlying etiopathogenesis of this inflammation remains unclear. IBD is probably caused by a combination of environmental and immune factors in genetically susceptible individuals. The process of diagnosing IBD involves several steps and is based on the exclusion of other causes of gastrointestinal signs and on the confirmation of the presence of inflammatory infiltration in the intestinal wall by histopathological assessment of biopsies. The treatment is based on anti-inflammatory and immunosuppressive drugs. In addition, dietotherapy, antibiotics, antiparasitic drugs, prebiotics, probiotics and supplementation of vitamin b12 are also used. For most patients, the response to treatment is satisfactory, but the maintenance of clinical remission in most of them may require anti-inflammatory drugs for the rest of their lives.

Alterations in the gut microbiota composition play a key role in the development of chronic diseases such as inflammatory bowel disease (IBD). The potential use of probiotics therefore gained attention, although outcomes were sometimes conflicting and results largely strain-dependent. The present study aimed to identify new probiotic strains that have a high potential for the management of this type of pathologies. Strains were selected from a large collection by combining different in vitro and in vivo approaches, addressing both anti-inflammatory potential and ability to improve the gut barrier function. We identified six strains with an interesting anti-inflammatory profile on peripheral blood mononuclear cells and with the ability to restore the gut barrier using a gut permeability model based on Caco-2 cells sensitized with hydrogen peroxide. The in vivo evaluation in two 2,4,6-trinitrobenzene sulfonic acid-induced murine models of colitis highlighted that some of the strains exhibited beneficial activities against acute colitis while others improved chronic colitis. Bifidobacterium bifidum PI22, the strain that exhibited the most protective capacities against acute colitis was only slightly efficacious against chronic colitis, while Bifidobacterium lactis LA804 which was less efficacious in the acute model was the most protective against chronic colitis. Lactobacillus helveticus PI5 was not anti-inflammatory in vitro but the best in strengthening the epithelial barrier and as such able to significantly dampen murine acute colitis. Interestingly, Lactobacillus salivarius LA307 protected mice significantly against both types of colitis. This work provides crucial clues for selecting the best strains for more efficacious therapeutic approaches in the management of chronic inflammatory diseases. The strategy employed allowed us to identify four strains with different characteristics and a high potential for the management of inflammatory diseases, such as IBD.

Prior Malignancy

Background: Treatment of inflammatory bowel disease (IBD) in patients with prior malignancy is challenging because therapeutic immunosuppression required for controlling IBD activity may increase the risk of cancer recurrence. Key Messages: Contrary to the observations in the post-transplant population, retrospective observational studies of IBD patients with prior malignancy have not demonstrated that immunosuppressive drugs increased significantly the risk of new or recurrent cancer. However, these studies are highly biased and do not permit the use of these drugs. Factors like the time since treatment completion, severity, and subtype of prior cancer should be weighed along with the current IBD activity before choosing the best therapeutic strategy. In practice, most cases of prior cancer require a delay of at least 2 years before starting or resuming immunosuppressants, including anti-TNF agents. This delay should be extended to 5 years in cancer with a high risk of recurrence including cancer of the urinary tract, gastrointestinal cancer, leukemias, and multiple myeloma. A special attention should be paid to cancers with a high risk of late metastasis (breast, melanoma, renal cell carcinoma). Enteral nutrition, Budesonide, mesalamine, and limited intestinal resection should be considered following the completion of cancer treatment and prior to the safe initiation of immunosuppressive treatment for IBD. Thiopurines should be avoided in case of prior Epstein-Barr virus-related lymphoma, HPV-related carcinomas, and cancer of the urinary tract. Methotrexate and anti-TNF agents seem to be safe except for the risk of recurrent melanoma for the latter. Conclusion: IBD patients with prior malignancy should benefit from individual decisions made on a case-by-case basis.

Diet plays a pivotal role in the onset and course of inflammatory bowel disease (IBD). Patients are keen to know what to eat to reduce symptoms and flares, but dietary guidelines are lacking. To advice patients, an overview of the current evidence on food (group) level is needed. This narrative review studies the effects of food (groups) on the onset and course of IBD and if not available the effects in healthy subjects or animal and in vitro IBD models. Based on this evidence the Groningen anti-inflammatory diet (GrAID) was designed and compared on food (group) level to other existing IBD diets. Although on several foods conflicting results were found, this review provides patients a good overview. Based on this evidence, the GrAID consists of lean meat, eggs, fish, plain dairy (such as milk, yoghurt, kefir and hard cheeses), fruit, vegetables, legumes, wheat, coffee, tea and honey. Red meat, other dairy products and sugar should be limited. Canned and processed foods, alcohol and sweetened beverages should be avoided. This comprehensive review focuses on anti-inflammatory properties of foods providing IBD patients with the best evidence on which foods they should eat or avoid to reduce flares. This was used to design the GrAID.

Inflammatory bowel disease is a condition that leads to gut pathologies such as abnormal lymphatic architecture, as well as to systemic comorbidities such as bone loss. Furthermore, current therapies are limited to low efficacy and incur side effects. Dietary interventions have been explored minimally, but may provide a treatment for improving gut outcomes and comorbidities. Indeed, plant-based soy protein has been shown to exert anti-inflammatory effects. Here, we tested the impact of a moderately elevated soy protein diet in a chronic, 2,4,6-trinitrobenzene sulfonic acid (TNBS)-induced colitis model on gut and bone inflammatory-mediated pathophysiological adaptations. Colitis was induced by intrarectal administration of TNBS. Gut histopathology was scored, and lymphatic structural changes and the local inflammatory state were assessed via immunofluorescence. In addition, the effects of gut inflammation on bone turnover and osteocyte proteins were determined via histomorphometry and immunohistochemistry, respectively. The moderately elevated soy protein diet produced improvements in both colonic and bone tissues. In TNBS animals given the soy protein intervention, colon histological scores were reduced and the abnormal lymphatic architecture resolved. There were also improvements in bone formation and reduced bone resorption. In addition, TNBS increased inflammatory cytokines such as tumor necrosis factor-α and receptor activator of nuclear factor κ-B ligand in the gut and bone, but this was resolved in both tissues with the dietary soy protein intervention. The moderately elevated soy protein diet mitigated gut and bone inflammation in a chronic, TNBS-induced colitis model, demonstrating the potential for soy protein as a potential anti-inflammatory dietary intervention for inflammatory bowel disease.

In recent years, there has been a steady increase in the incidence of inflammatory bowel disease (IBD) worldwide. Treatment of ulcerative colitis and Crohn’s disease has become more effective thanks to the emergence of biological therapies, increased access to specialized care and a “treat to target” approach. However, with an increase in the life expectancy of patients with IBD, there is an increase in the number of persons with comorbidity, primarily with a combination of IBD with cardiovascular pathology. Environmental factors lead to a change in the diversity and density of colonization of the intestinal microbiota, a violation of its barrier function, immune dysregulation, which in turn leads to the development of chronic inflammatory diseases and atherosclerosis. Levels of proinflammatory cytokines, C-reactive protein, and homocysteine increase in IBD, leading to endothelial dysfunction and atherosclerosis. In addition, inflammatory processes in IBD promote hypercoagulation, which occurs both in the thromboembolic complications and in the pathogenesis of the disease itself. It has been suggested that medical pathogenetic therapy for IBD is also associated with the risk of cardiovascular disease. In this review, we systematize the available data on the risks of cardiovascular diseases in patients with IBD. A literature search containing information on relevant studies was carried out in PubMed and Google Scholar systems with the keywords: inflammatory bowel disease, cardiovascular disease, inflammation, atherosclerosis.
