Ibd and probiotics

Taekil Eom, Yong Sung Kim, Chang Hwan Choi, Michael J Sadowsky, Tatsuya Unno
Inflammatory bowel disease (IBD) is a result of chronic inflammation caused, in some part, by dysbiosis of intestinal microbiota, mainly commensal bacteria. Gut dysbiosis can be caused by multiple factors, including abnormal immune responses which might be related to genetic susceptibility, infection, western dietary habits, and administration of antibiotics. Consequently, the disease itself is characterized as having multiple causes, etiologies, and severities. Recent studies have identified >200 IBD risk loci in the host...

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...

Inflammatory bowel disease (IBD) is a multifactorial chronic inflammatory disease of the gastrointestinal tract, characterized by cycles of acute flares, recovery and remission phases. Treatments for accelerating tissue restitution and prolonging remission are scarce, but altering the microbiota composition to promote intestinal homeostasis is considered a safe, economic and promising approach. Although probiotic bacteria have not yet fulfilled fully their promise in clinical trials, understanding the mechanism of how they exert beneficial effects will permit devising improved therapeutic strategies...

BACKGROUND: An altered gut microbiota balance is involved in the pathogenesis of inflammatory bowel disease (IBD), and several probiotic strains are used as dietary supplements to improve intestinal health. We evaluated the therapeutic effect of 12 probiotics in combination with prebiotics, rosavin, and zinc in the dextran sodium sulfate (DSS)-induced colitis mouse model. METHODS: The probiotic complex or the combination drug was administered orally to mice with DSS-induced colitis, and the body weight, disease activity index, colon length, and histopathological parameters were evaluated...

In a previous paper we showed that the yeast Pichia pastoris X-33 grown in parboiled rice effluent supplemented with glycerol byproduct from the biodiesel industry improved the quality of the effluent. In this paper we show the validation of this yeast (PPE) as probiotic for broilers. Its effect on feed efficiency and immunomodulation was compared with the same yeast grown in yeast peptone dextrose medium (PPY), with Saccharomyces boulardii (SBY) and with the controls fed unsupplemented feed (CON). One-day-old female chicks were vaccinated against infectious bursal disease (IBD) and the titers of anti-IBD antibodies were measured by ELISA...

Gut Inflammatory bowel disease (IBD) is a group of chronic gastrointestinal disorders characterised by relapsing and remitting inflammation of the gastrointestinal tract. The two most common types of IBDs are ulcerative colitis and Crohn's disease. Patients with glycogen storage disease (GSD) type Ia present with gastrointestinal symptoms such as recurrent abdominal pain, bloating and changes in stool form or frequency, which is clinically difficult to distinguish from IBD. We report the case of a 36-year-old man with GSD type Ia and IBD-like disease...

Nutritional strategies have been explored as primary or adjunct therapies for inflammatory bowel disease (IBD). Exclusive enteral nutrition is effective for the induction of remission in Crohn disease and is recommended as a first-line therapy for children. Dietary strategies focus on adjusting the ratio of consumed nutrients that are proinflammatory or antiinflammatory. Treatments with dietary supplements focus on the antiinflammatory effects of the individual supplements (eg, curcumin, omega-3 fatty acids, vitamin D) or their positive effects on the intestinal microbiome (eg, prebiotics, probiotics)...

Resistance to a drug and the suppression of inflammatory disorders with immunosuppressive drugs might have happened upon exposure to natural compounds during evolution. Streptomycetes are soil bacteria, but they produce therapeutic drugs. They have been reported to be the low-abundant members of mucosal microbiomes with a higher prevalence in nonhumans ingesting soil compared to humans. Their lower abundance in the human microbiome might be the representations of our current hygienic lifestyle. We suggest that the Streptomyces bacteria producing antiproliferative/immunosuppressive compounds (e...

BACKGROUND: The use of complementary and alternative medicine (CAM) has been associated with adverse effects and self-imposed dietary restrictions. The prevalence of its use in Asian children with inflammatory bowel disease (IBD) is unknown. We aimed to determine the prevalence, types, and factors associated with the use of CAM among children with IBD from Singapore and Malaysia, and to ascertain if dietary restriction was prevalent in patients who used CAM. METHODS: A cross-sectional study was conducted in which parents of children with IBD attending two tertiary pediatric IBD referral centres in Singapore and Malaysia were interviewed...

Disruption of the balance among the microbiota, epithelial cells, and resident immune cells in the intestine is involved in the pathogenesis of inflammatory bowel disease (IBD). Probiotics exert protective effects against IBD, and probiotic commensal Lactobacillus species are common inhabitants of the natural microbiota, especially in the gut. To investigate the effects of Lactobacillus acidophilus on the development of IBD, L. acidophilus was administered orally in mice with dextran sodium sulfate (DSS)-induced colitis...

The term in ammatory bowel diseases (IBD) refers to a group of idiopathic, chronic intestinal diseases characterized by a di use in ltration of in ammatory cells into the lamina propria of the intestine. The pathogenesis of IBD is unknown. The most common signs described are diarrhoea, vomit, and progressive weight loss. In order to make a de nitive diagnosis, though, the presence of in ammatory cells in ltration must be evident on histopathologic analysis. The therapeutic approach has 2 main goals: decrease the in ammatory response and remove possible antigenic sources, such as food components or intestinal micro ora...

Individuals with inflammatory bowel disease (IBD) are at a high risk for developing colitis-associated cancer (CAC). Strategies to block the process from IBD to CAC should be considered. In the experiment, we aim to explore the chemopreventive efficacy of the probiotic cocktail Bifico and its potential mechanism in azoxymethane (AOM) and dextran sodium sulphate (DSS) induced colitis-associated cancer in mice. Oral pretreatment of Bifico was adopted to evaluate its protective effect. The colorectums of thirty-five C57BL/6 mice were collected and examined for degree of inflammation and tumorigenesis...

Inflammatory bowel disease (IBD), including ulcerative colitis and Crohn's disease, is a chronic and relapsing inflammatory disorder of the intestine. Although its incidence is increasing globally, the precise etiology remains unclear and a cure for IBD has yet to be discovered. The most accepted hypothesis of IBD pathogenesis is that complex interactions between genetics, environmental factors, and the host immune system lead to aberrant immune responses and chronic intestinal inflammation. The human gut harbors a complex and abundant aggregation of microbes, collectively referred to as the gut microbiota...

Inflammatory bowel disease (IBD) is a chronically relapsing inflammatory disorder of the gastrointestinal tract. Current IBD treatments have poor tolerability and insufficient therapeutic efficacy, thus, alternative therapeutic approaches are required. Recently, a number of dietary supplements have emerged as promising interventions. In the present study oral administration of a carotenoid (4,4'-diaponeurosporene)-producing Bacillus subtilis markedly ameliorated dextran sulfate sodium salt-induced mouse colitis, as demonstrated by a reduction in weight loss and the severity of bleeding, which indicated that 4,4'-diaponeurosporene may have beneficial effects on treatments for colitis...

Gut microbiota influences the central nervous system disorders such as Alzheimer's disease (AD). The prebiotics and probiotics can improve the host cognition. A previous study demonstrated that fructooligosaccharides from Morinda officinalis (OMO) exert effective memory improvements in AD-like animals, thereby considered as potential prebiotics; however, the underlying mechanism still remains enigma. Thus, the present study investigated whether OMO is effective in alleviating AD by targeting the microbiota-gut-brain axis...

The goal of this study was explore the role of indoleamine 2, 3-dioxygenase (IDO) in the therapeutic effect of probiotics on inflammatory bowel disease (IBD). Trinitrobenzene sulfonic acid (TNBS) was used to induce colitis in mice and 1-methyltryptophan (1-MT) to block expression of IDO. Clinical manifestations and macroscopic and microscopic colonic changes were assessed using a disease activity index (DAI), the Wallace-Keenan, and Curtner scoring systems, respectively. Expression of colonic IDO was detected by western blot...

Evidence indicates that the gut microbiota and/or interactions between the microbiota and the host immune system are involved in the pathogenesis of inflammatory bowel disease (IBD). Strategies that target the microbiota have emerged as potential therapies and, of these, probiotics have gained the greatest attention. Data derived from animal models of IBD have revealed the potential of several bacterial strains to modify the natural history of IBD. However, thought there is some evidence for efficacy in ulcerative colitis and in pouchitis, in particular, there has been little indication that probiotics exert any benefit in Crohn disease...

Context • Crohn's disease and ulcerative colitis result in similar gastrointestinal (GI) symptoms, including pain, diarrhea, stools with mucus or blood, and ulceration or tissue damage within the alimentary canal. Gut microbiota play a crucial role in triggering, maintaining, and exacerbating inflammatory bowel disease (IBD). Probiotics might help to rebalance the gut flora in a positive way, shifting from pro- to anti-inflammatory. Objectives • The study intended to investigate the safety and use of probiotics and the biological effects of probiotic bacteria on IBD...
