Protective Effect of Luminal Uric Acid Against Indomethacin-Induced Enteropathy: Role of Antioxidant Effect and Gut Microbiota. Dig Dis Sci 2022; 67:121-133. [PMID: 33569665 DOI: 10.1007/s10620-021-06848-z] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/22/2020] [Accepted: 01/14/2021] [Indexed: 12/12/2022]
Abstract
BACKGROUND Uric acid (UA) has anti- and pro-inflammatory properties. We previously revealed that elevated serum UA levels provide protection against murine small intestinal injury probably via luminal UA secreted in the small intestine. Luminal UA may act as an antioxidant, preventing microbiota vulnerability to oxidative stress. However, whether luminal UA is increased under hyperuricemia and plays a protective role in a dose-dependent manner as well as the mechanism by which luminal UA exerts its protective effects on enteropathy remains unknown. METHODS Inosinic acid (IMP) (1000 mg/kg, i.p.) was administered to obtain high serum UA (HUA) and moderate serum UA (500 mg/kg IMP, i.p.) mice. UA concentrations and levels of oxidative stress markers in the serum and intestine were measured. Mice received indomethacin (20 mg/kg, i.p.) to evaluate the effects of UA on indomethacin-induced enteropathy. Reactive oxygen species (ROS) on the ileal mucosa were analyzed. The fecal microbiota of HUA mice was transplanted to investigate its effect on indomethacin-induced enteropathy. RESULTS IMP increased luminal UA dose-dependently, with higher levels of luminal antioxidant markers. Indomethacin-induced enteropathy was significantly ameliorated in both UA-elevated groups, with decreased indomethacin-induced luminal ROS. The microbiota of HUA mice showed a significant increase in α-diversity and a significant difference in β-diversity from the control. Fecal microbiota transplantation from HUA mice ameliorated indomethacin-induced enteropathy. CONCLUSIONS The protective role of luminal UA in intestinal injury is likely exerted via oxidative stress elimination and microbiota composition modulation, preferably for gut immunity. Therefore, enhancing anaerobic conditions using antioxidants is a potential therapeutic target.

Association of Dietary Fatty Acid Intake With the Development of Ulcerative Colitis: A Multicenter Case-Control Study in Japan. Inflamm Bowel Dis 2021; 27:617-628. [PMID: 32507894 DOI: 10.1093/ibd/izaa140] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/13/2019] [Indexed: 02/06/2023]
Abstract
BACKGROUND Dietary fatty acids can affect chronic intestinal inflammation and have been reported to be associated with the development of ulcerative colitis (UC), mainly in Europe and the United States. The association of dietary intake of fatty acids and the risk for UC was investigated in Japan, where dietary habits lead to lower meat and higher fish consumption than in Western countries. METHODS A multicenter case-control study of 83 newly diagnosed patients with UC and 128 age- and sex-matched control patients in the hospital was conducted from 2008 to 2014. Dietary fatty acid intake in the preceding 1 month and 1 year were examined using a self-administered diet history questionnaire that was developed for Japanese people. RESULTS About 92% of patients had experienced the first symptoms of UC within the preceding 11 months. Regarding dietary habits in the preceding year, the risk for UC was significantly decreased in patients who consumed n-6/n-3 polyunsaturated fatty acids at a ratio of ≥5.2 (odds ratio [OR] = 0.26; 95% confidence interval [CI], 0.10-0.68). Conversely, an increased risk for UC was observed in the highest tertiles of consumption of docosahexaenoic acid (OR = 7.22; 95% CI, 2.09-24.95), eicosapentaenoic acid (OR = 6.91; 95% CI, 1.88-25.44), and docosapentaenoic acid (OR = 4.83; 95% CI, 1.56-14.95). CONCLUSIONS The ratio of n-6/n-3 polyunsaturated fatty acid intake was associated with a decreased risk for UC development. However, high intakes of docosahexaenoic acid, eicosapentaenoic acid, and docosapentaenoic acid may increase the risk for UC development.

Abstract
Context: Paracetamol (PAR) and diclofenac (DF) are the most popular consumed analgesics and anti-inflammatory medications.Objective: This study aimed to explore the protective effect of betanin (Bet) against PAR or DF induced hepato-renal damage in rats.Methods: Rats were randomly divided into five groups: Normal control (NC) group rats were given saline only. PAR group rats received PAR (400 mg/kg). PAR/Bet treated group rats administered PAR (400 mg/kg) plus Bet (25 mg/kg). DF group rats received DF (10 mg/kg). DF/Bet treated group rats administered DF (10 mg/kg) plus Bet (25 mg/kg). All drugs were given by gavage for 28 consecutive days.Results: PAR and DF administration in high dose and long-time induced liver and kidney injury, disrupted serum lipid profile, enhanced serum levels of inflammatory and oxidative stress markers, triggered DNA fragmentation and caused drastic changes in the histopathological pictures of the two organs. Bet supplementation succeeded to ameliorate most of the biochemical changes and protected DNA from damage as obtained from comet assay. Histological features in H&E taken to different groups also mirrors this findings.Conclusion: Bet exerted a potential anti-inflammatory and antioxidant effect against hepato-renal damage induced by PAR or DF overconsumption.

Abstract
Despite the benefit of insulin, blockade of autoimmune attack and regeneration of pancreatic islets are ultimate goals for the complete cure of type 1 diabetes (T1D). Long-term consumption of ω-3 polyunsaturated fatty acids (PUFAs) is known to suppress inflammatory processes, making these fatty acids candidates for the prevention and amelioration of autoimmune diseases. Here, we explored the preventative and therapeutic effects of ω-3 PUFAs on T1D. In NOD mice, dietary intervention with ω-3 PUFAs sharply reduced the incidence of T1D, modulated the differentiation of Th cells and Tregs, and decreased the levels of IFN-γ, IL-17, IL-6, and TNF-α. ω-3 PUFAs exerted similar effects on the differentiation of CD4+ T cells isolated from human peripheral blood mononuclear cells. The regulation of CD4+ T cell differentiation was mediated at least in part through ω-3 PUFA eicosanoid derivatives and by mTOR complex 1 (mTORC1) inhibition. Importantly, therapeutic intervention in NOD mice through nutritional supplementation or lentivirus-mediated expression of an ω-3 fatty acid desaturase, mfat-1, normalized blood glucose and insulin levels for at least 182 days, blocked the development of autoimmunity, prevented lymphocyte infiltration into regenerated islets, and sharply elevated the expression of the β cell markers pancreatic and duodenal homeobox 1 (Pdx1) and paired box 4 (Pax4). The findings suggest that ω-3 PUFAs could potentially serve as a therapeutic modality for T1D.

Abstract
BACKGROUND Nonsteroidal anti-inflammatory drugs (NSAIDs) are popular painkillers, but they have serious side effects, not only in the upper gastrointestinal tract but also in the small intestine. It is well known that psychological stress may exacerbate various gastrointestinal diseases. The aim of this study was to determine whether psychological stress exacerbates NSAID enteropathy and to determine the possible underlying mechanisms for this. METHODS Experiment 1: mice were exposed to water avoidance stress (WAS) or sham stress for 1 h per day for 8 consecutive days, and then enteropathy was induced by indomethacin. Experiment 2: cecal contents from stress (-) or (+) mice were transplanted into mice that had received antibiotics and in which NSAID enteropathy had been induced without WAS. Experiment 3: mifepristone, a glucocorticoid receptor antagonist, was injected before WAS for 8 days. Small intestinal injury, mRNA expression of TNFα, intestinal permeability, and the microbial community were assessed. RESULTS Psychological stress exacerbated NSAID enteropathy and increased intestinal permeability. Psychological stress induced changes in the ileal microbiota that were characterized by increases in the total number of bacteria and the proportion of Gram-negative bacteria. The increased susceptibility to NSAIDs and intestinal permeability due to WAS was transferable via cecal microbiota transplantation. The increased permeability and aggravation of NSAID enteropathy caused by WAS were blocked by the administration of mifepristone. CONCLUSIONS This study demonstrated a relationship between NSAID enteropathy and psychological stress, and showed the utility of studying the intestinal microbiota in order to elucidate the pathophysiology of NSAID enteropathy. It also showed the impact of stress on the intestinal microbiota and the mucosal barrier in gastrointestinal diseases.
