The two most important bacterial phyla in the gastrointestinal tract, Firmicutes and Bacteroidetes, have gained much attention in recent years. The Firmicutes/Bacteroidetes (F/B) ratio is widely accepted to have an important influence in maintaining normal intestinal homeostasis. Increased or decreased F/B ratio is regarded as dysbiosis, whereby the former is usually observed with obesity, and the latter with inflammatory bowel disease (IBD). Probiotics as live microorganisms can confer health benefits to the host when administered in adequate amounts. There is considerable evidence of their nutritional and immunosuppressive properties including reports that elucidate the association of probiotics with the F/B ratio, obesity, and IBD. Orally administered probiotics can contribute to the restoration of dysbiotic microbiota and to the prevention of obesity or IBD. However, as the effects of different probiotics on the F/B ratio differ, selecting the appropriate species or mixture is crucial. The most commonly tested probiotics for modifying the F/B ratio and treating obesity and IBD are from the genus Lactobacillus. In this paper, we review the effects of probiotics on the F/B ratio that lead to weight loss or immunosuppression.

Crohn’s disease is a chronic relapsing gastrointestinal condition. It is an inflammatory bowel disease that can affect any part of the gastrointestinal tract from mouth to anus, but most commonly affects the terminal ileum and colon. Individuals can present with a wide variety of symptoms, but diarrhoea, abdominal pain and weight loss are the most common. It is a rare condition, but GPs play an important role in recognising Crohn’s disease and supporting patients through their lifelong treatment.

The endothelium has a crucial role in proper hemodynamics. Inflammatory bowel disease (IBD) is mainly a chronic inflammatory condition of the gastrointestinal tract. However, considerable evidence points to high cardiovascular risk in patients with IBD. This review positions the basic mechanisms of endothelial dysfunction in the IBD setting (both clinical and experimental). Furthermore, we review the main effects of drugs used to treat IBD in endothelial (dys)function. Moreover, we leave challenging points for enlarging the therapeutic arsenal for IBD with new or repurposed drugs that target endothelial dysfunction besides inflammation.

The intestine can be the target of several immunologically mediated diseases, including graft-versus-host disease (GVHD) and inflammatory bowel disease (IBD). GVHD is a life-threatening complication that occurs after allogeneic hematopoietic stem cell transplantation. Involvement of the gastrointestinal tract is associated with a particularly high mortality. GVHD development starts with the recognition of allo-antigens in the recipient by the donor immune system, which elicits immune-mediated damage of otherwise healthy tissues. IBD describes a group of immunologically mediated chronic inflammatory diseases of the intestine. Several aspects, including genetic predisposition and immune dysregulation, are responsible for the development of IBD, with Crohn’s disease and ulcerative colitis being the two most common variants. GVHD and IBD share multiple key features of their onset and development, including intestinal tissue damage and loss of intestinal barrier function. A further common feature in the pathophysiology of both diseases is the involvement of cytokines such as type I and II interferons (IFNs), amongst others. IFNs are a family of protein mediators produced as a part of the inflammatory response, typically to pathogens or malignant cells. Diverse, and partially paradoxical, effects have been described for IFNs in GVHD and IBD. This review summarizes current knowledge on the role of type I, II and III IFNs, including basic concepts and controversies about their functions in the context of GVHD and IBD. In addition, therapeutic options, research developments and remaining open questions are addressed.

Inflammatory bowel disease (IBD) is characterized by chronic inflammation of the gastrointestinal tract and is strongly associated with intestinal immunity and the microbiome.

Cilj ovog rada bio je istražiti korisnost upotrebe imunohistokemijske metode (IHK) zajedno s histopatološkom pretragom u dijagnosticiranju i razlikovanju alimentarnog limfoma (AL) od upalne bolesti crijeva (UBC). U istraživanju su korišteni arhivski histopatološki nalazi i preparati tkiva, parafinski blokovi i stakalca. Prema pripadnosti pasmina podijelili u tri skupine malu, srednju ili veliku skupinu pasa. Cilj istraživanja bio je utvrditi povezanost pojedinih patoloških promjena ovisno o skupini pasa, dobi i spolu. Obavljenim istraživanjem zabilježili smo da je srednja vrijednost dobi u skupini malih pasmina pasa iznosila 7,58±3,59 godina, u skupini srednjih pasmina 7,45±3,04 godina te u skupini velikih pasmina 6,58±3,47 godina. Prosječna dob pasa oboljelih od alimentarnog limfoma iznosila je 8,8 godina, za razliku od upalne bolesti crijeva gdje je iznosila 7,0 godina. Unutar sve tri skupine pasa zabilježen je veći broj jedinki muškog spola. Najveći udio biopsiranih uzoraka (70,73 %) analiziran je iz tkiva tankog crijeva; po 8 uzoraka (27,59 %) iz male skupine pasa, 11 uzoraka iz srednje skupine (37,93 %) te po 10 uzoraka iz velike skupine pasa (34,48 %). Udio biopsiranog tkiva želudca bio je nešto niži (24,39 %) dok je tkivo debelog crijeva uzorkovano u samo dva psa (4,88 %). Histopatološkom analizom utvrđeno je 16 slučajeva upalne bolesti crijeva (45,71 %), 7 slučajeva limfoma (20,00 %), 9 slučajeva suspektne upale (25,71 %) te 3 slučaja suspektne upale/limfoma (8,58 %). Nakon provedene IHK metode ustanovljeno je da je u 6 slučajeva dijagnoza donesena histopatološkom evaluacijom potvrđena, u 5 slučajeva je opovrgnuta dok je u 5 slučajeva IHK metoda bila korisna kako bi razlučili AL od UBC. Utvrđene su značajne razlike (P<0,05) između dijagnoze upalne bolesti crijeva te limfoma ustanovljene patohistološkom pretragom te imunohistokemijskom metodom. Ustanovljena je češća pojavnost T staničnog limfoma u tankom crijevu dok je pojavnost B staničnog limfoma učestalija u želudcu. Povezanost s tendencijom učinka zabilježena je između patohistološke dijagnoze i CD3 biljega (r=-0.34; P=0,08) odnosno između patohistološke dijagnoze i CD79 biljega (r=0.36; P=0,09) s nešto nižom razinom povezanosti između patohistološke dijagnoze i dijagnoze IHK (r=0.21; P=0,34). Na temelju rezultata našeg istraživanja može se zaključiti da je imunohistokemijska metoda korisna za potvrdu dijagnoze i razlikovanje alimentarnog limfoma i upalne bolesti crijeva.

Primary gastrointestinal non-Hodgkin’s lymphomas are rare tumors which account for about 0.9% of all gastrointestinal tract tumors. They are usually associated with inflammatory bowel disease, previous radiotherapy, and renal transplantation. We report a case of non-Hodgkin’s lymphoma involving the ileocecal region in a 46-year-old gentleman who presented with acute abdominal pain that mandated emergency laparotomy.

The complement and contact systems may be involved in the pathophysiological process of inflammatory bowel disease (IBD). C1 inhibitor (C1INH) is the most important inhibitor of both the complement and contact systems. We evaluated the role of these systems and the effect of both active and inactive forms of C1INH (iC1INH) in dextran sulfate sodium (DSS)-induced colitis mouse model. Three percent DSS was used in drinking water to induce colitis in complement C3-deficient (C3−/−) mice, bradykinin type 2 receptor deficient (Bk2R−/−) mice, and C57BL/6 mice. After ten days DSS exposure, C3−/− mice exhibited markedly less weight loss than wild-type (WT) mice (12 ± 3.3% vs. 30 ± 1.2%, P < 0.05) and developed a milder disease-activity index (DAI), histological score, colon shortening, and myeloperoxidase (MPO) elevation ( P < 0.05, respectively). The Bk2R−/− mice were not protected from the disease. Seven-day treatment with either native C1INH or iC1INH reduced the severity of the disease in WT mice, as indicated by decreased weight loss (15 ± 1.8%, 14 ± 2.1% vs. 30 ± 1.2%, P < 0.05, respectively), DAI, intestinal tissue damage, and MPO elevation compared with untreated WT DSS control mice ( P < 0.05, respectively). These findings suggest that complement plays a role in the development of DSS-induced colitis and that blockade of the complement system might be useful for the acute phase of IBD treatment. C1INH, however, leads to an amelioration of DSS-induced colitis via a mechanism that does not involve the inhibition of complement or contact system activation but does result in significant suppression of leukocyte infiltration.
