A 20-year-old female was diagnosed with ulcerative colitis (UC) at age 14 and primary sclerosing cholangitis (PSC) at age 16. The PSC was successfully treated with high doses of oral vancomycin; however, the UC was more difficult to manage. After many drug treatments failed to treat the UC, the patient began following the specific carbohydrate diet (SCD). This report documents fecal microbiome changes resulting from following the SCD for two weeks. The DNA extracted from fecal samples was subjected to 16S rRNA gene sequencing to quantify bacterial species abundance...

Excessive hydrogen sulfide (H2 S) production from gut microbial metabolism may have clinically important relevance in the pathogenesis of gut disorders, including ulcerative colitis. However, little is known regarding factors that alter its production. Using a newly-designed in vitro gas-profiling technology, the study aimed to verify real-time H2 S measurement reproducibility and thereafter, assess its production following exposure to dietary factors and 5-aminosalicylate acid (5-ASA). Measurements of H2 S, carbon dioxide, hydrogen and methane measurements were compared between gas-profiling systems...

Galectins, a family of animal lectins characterized by their affinity for N-acetyllactosamine-enriched glycoconjugates, modulate several immune cell processes shaping the course of innate and adaptive immune responses. Through interaction with a wide range of glycosylated receptors bearing complex branched N-glycans and core 2-O-glycans, these endogenous lectins trigger distinct signaling programs thereby controling immune cell activation, differentiation, recruitment and survival. Given the unique features of mucosal inflammation and the differential expression of galectins throughout the gastrointestinal tract, we discuss here key findings on the role of galectins in intestinal inflammation, particularly Crohn's disease, ulcerative colitis, and celiac disease (CeD) patients, as well as in murine models resembling these inflammatory conditions...

OBJECTIVE: To observe the effect of different-doses of herbal cake-partitioned moxibustion (Moxi) on histopathological changes of the damaged colon tissue in rats with ulcerative colitis (UC), so as to select an optimal dosage of Moxi in the treatment of UC. METHODS: Sixty-three male Sprague Dawley (SD) rats were randomized into 7 groups: normal control, model, medication, and 1, 2, 3 and 4 moxa-cone Moxi ( n =9 rats per group). The UC model was developed by subcutaneous injection of emulsion (1 mL) containing colon mucosa-prepared protein suspension and complete Freund's adjuvant into the toes, groin and back...

Ulcerative colitis is a well-known inflammatory bowel disease. Although there are drugs that are effective against this disease, the prevention and attenuation of ulcerative colitis by food rich in functional ingredients without side effects is desired because some drugs have side effects. In this study, we investigated the effects of yuzu (Citrus junos Tanaka), a citrus fruit native to northeast Asia, on a mouse dextran sulfate sodium (DSS)-induced colitis model. Mice given drinking water containing DSS showed significant weight loss, colon shortening, diarrhea, and visible fecal blood...

Inflammatory bowel diseases (IBD) comprise two disorders of idiopathic chronic intestinal inflammation that affect about three million people worldwide: Crohn's disease and ulcerative colitis. Nowadays, the first-line of treatment for patients with mild to moderate symptoms of IBD comprises corticosteroids, immunosuppressants, antibiotics, and biological agents. Unfortunately, none of these drugs are curative, and their long-term use may cause severe side effects and complications. Almost 40% of IBD patients use alternative therapies to complement the conventional one, and flavonoids are gaining attention for this purpose...

Background and Aims: Alterations in short chain fatty acid metabolism, particularly butyrate, have been reported in inflammatory bowel disease, but results have been conflicting because of small study numbers and failure to distinguish disease type, activity or other variables such as diet. We performed a comparative assessment of the capacity of the microbiota for butyrate synthesis, by quantifying butyryl-CoA:acetate CoA-transferase [BCoAT] gene content in stool from patients with Crohn's disease [CD; n = 71], ulcerative colitis [UC; n = 58] and controls [n = 75], and determined whether it was related to active vs inactive inflammation, microbial diversity, and composition and/or dietary habits...

Inflammatory bowel diseases (IBDs) are mainly represented by ulcerative colitis and Crohn's disease, and the increase in the incidence tends to follow the rapid industrialization and lifestyle of modern societies. FODMAP (fermentable oligosaccharides, disaccharides, monosaccharides, and polyols) consist of molecules that are poorly absorbed in the small intestine and are fermented by bacteria in the colon leading to symptoms such as bloating, flatulence, diarrhea, and abdominal pain. Reduction of the ingestion of FODMAP could reduce the symptoms and improve the quality of life...

BACKGROUND: Inflammatory bowel diseases (IBD), which include ulcerative colitis and Crohn's disease, cause chronic inflammation of the digestive tract in approximately 1.6 million Americans. A signature of IBD is dysbiosis of the gut microbiota marked by a significant reduction of obligate anaerobes and a sharp increase in facultative anaerobes. Numerous experimental studies have shown that IBD is strongly correlated with a decrease of Faecalibacterium prausnitzii and an increase of Escherichia coli...

Diet strongly affects gut microbiota composition, and gut bacteria can influence the colonic mucus layer, a physical barrier that separates trillions of gut bacteria from the host. However, the interplay between a Western style diet (WSD), gut microbiota composition, and the intestinal mucus layer is less clear. Here we show that mice fed a WSD have an altered colonic microbiota composition that causes increased penetrability and a reduced growth rate of the inner mucus layer. Both barrier defects can be prevented by transplanting microbiota from chow-fed mice...

In the present study, we have investigated the effects of polyphenol-rich infusions from carob leaves and OFI-cladodes on inflammation associated with obesity and dextran sulfate sodium (DSS)-induced ulcerative colitis in Swiss mice. In vitro studies revealed that aqueous extracts of carob leaves and OFI-cladodes exhibited anti-inflammatory properties marked by the inhibition of IL-6, TNF-α and nitric oxide (NO) production in lipopolysaccharide (LPS)-stimulated RAW 264.7 cells concomitant with NF-κβ nucleus translocation inhibition...

Eating habits have changed dramatically over the years, leading to an imbalance in the ratio of n-6/n-3 polyunsaturated fatty acids (PUFAs) in favour of n-6 PUFAs, particularly in the Western diet. Meanwhile, the incidence of inflammatory bowel disease (IBD) is increasing worldwide. Recent epidemiological data indicate the potential beneficial effect of n-3 PUFAs in ulcerative colitis (UC) prevention, whereas consumption of a higher ratio of n-6 PUFAs versus n-3 PUFAs has been associated with an increased UC incidence...

The gastrointestinal microbiome is a complex echosystem that establishes a symbiotic, mutually beneficial relation with the host, being rather stable in health, but affected by age, drugs, diet, alcohol, and smoking. Alcohol and smoking contribute to changes in the stomach and affect H pylori-related disorders including the risk of gastric cancer. In the small intestine and in the colon alcohol causes depletion of bacteria with anti-inflammatory activity, eventually resulting in intestinal damage with "leaky gut"...

BACKGROUND: Crohn's disease (CD) involves intensive immunologic responses to food antigens. Exclusive enteral nutrition (EEN) showed efficacy in inducing disease remission. However, relapse commonly occurred when normal diet was reintroduced. We aimed to investigate the food-specific IgG antibodies of CD, and clarify the effects of exclusion diet guided by food-specific antibodies on remission maintenance after EEN. METHODS: All available data of food-specific antibodies were retrieved from the database and analyzed for the diagnostic value...

The incidence of inflammatory bowel disease (IBD) is steadily on the rise in Western and in developing countries paralleling the increase of westernized diets, characterized by high protein and fat as well as excessive sugar intake, with less vegetables and fiber. Furthermore, nutrition is involved in several aspects of pediatric IBD, ranging from disease etiology to induction and maintenance of remission of disease. Exclusive enteral nutrition (EEN) has been shown to induce remission, including in patients with isolated colonic disease, and leads to mucosal healing in Crohn disease...

Neonatal inflammatory bowel disease (IBD) is a subclass of very early onset IBD that includes children younger than 1 month. It is characterized by more colonic involvement and monogenetic etiology, resistance to classical anti-inflammatory/immunomodulatory treatments and associated with colitis in first-degree family members. Herein we report a 3 month-old girl who was admitted with bloody diarrhea since 10 days of age. Her symptoms persist despite diet elimination. She was diagnosed with neonatal ulcerative colitis (UC) based on clinical, laboratory and histopathological examination...

INTRODUCTION: High intake of dietary n-3 polyunsaturated fatty acids (PUFA) is associated with a decreased risk of ulcerative colitis (UC) and Crohn's disease (CD). However, results have been heterogeneous suggesting that genetic variations in PUFA metabolism may modify this risk. METHODS: We conducted a case-control study nested within 2 prospective cohorts, the Nurses' Health Study (NHS) and NHS II. Among women providing blood (n = 62,437) or buccal cells (n = 59,543) for genotyping, we confirmed new diagnoses of CD or UC...

Patients with longstanding ulcerative colitis have an increased risk of colorectal cancer. Mouse models for colitis-associated tumors are indispensable for the development of novel strategies for prevention and intervention, as well as an improved understanding of the mechanisms underlying tumor formation. The present study examined whether stereomicroscopic observations with dye-application were able to detect and discriminate tumors in a colitis-associated tumor model in mice. Colonic tumors were induced in C57BL/6 mice by 15 cycles of treatment with dextran sulfate sodium (DSS) in drinking water...
