Rosa roxburghii Tratt (Cili) has a more effective capacity in alleviating DSS-induced colitis compared to Vitamin C through B cell receptor pathway. Food Res Int 2024; 195:114950. [PMID: 39277228 DOI: 10.1016/j.foodres.2024.114950] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/12/2024] [Revised: 08/13/2024] [Accepted: 08/20/2024] [Indexed: 09/17/2024]
Abstract
Rosa roxburghii Tratt (RRT), a traditional Chinese plant known as the 'King of Vitamin C (VitC; ascorbic acid, AsA)', contains a wealth of nutrients and functional components, including polysaccharides, organic acids, flavonoids, triterpenes, and high superoxide dismutase (SOD) activity. The various functional components of RRT suggest that it may theoretically have a stronger potential for alleviating colitis compared to VitC. This study aims to verify whether RRT has a stronger ability to alleviate colitis than equimolar doses of VitC and to explore the mechanisms underlying this improvement. Results showed that RRT significantly mitigated body weight loss, intestinal damage, elevated inflammation levels, and compromised barriers in mice induced by Dextran sulfate sodium (DSS). Additionally, RRT enhanced the diversity and composition of intestinal microbiota in these DSS-induced mice. Colon RNA sequencing analysis revealed that compared to VitC, RRT further downregulated multiple immune-related signaling pathways, particularly the B cell receptor (BCR) pathway, which is centered around genes like Btk and its downstream PI3K-AKT, NF-κB, and MAPK signaling pathways. Correlation analysis between microbiota and genes demonstrated a significant relationship between the taxa improved by RRT and the key genes in the BCR and its downstream signaling pathways. Overall, RRT exhibited superior capabilities in alleviating DSS-induced colitis compared to VitC by decreasing intestinal inflammation and modulating BCR and its downstream signaling pathways, potentially regulated by the improved intestinal microbiota.

Abstract
Irritable Bowel Syndrome (IBS) is a common functional pathology of the gastrointestinal tract (GIT) across the globe. The prevalence rate of IBS varies across the regions. In the present systematic review, we aim to investigate the prevalence of IBS in Arab countries in recent years. To identify relevant studies, a comprehensive search was undertaken in various databases including CINAHL (Cumulated Index to Nursing and Allied Health Literature) Ultimate, Scopus, PubMed, and Web of Science. Furthermore, Google Scholar was also explored to identify relevant studies. The inclusion criteria included studies that assessed IBS in the Arab world and were published in the English language. Fifty-two cross-sectional studies from seven countries, encompassing 51,683 participants, were included. The majority of the included studies were conducted in Saudi Arabia (n=40), followed by Jordan (n=4) and Egypt (n=3). The highest prevalence rates were reported by studies from Saudi Arabia, Lebanon, and Jordan. Low prevalence rates (<20%) were noted in 19 studies included in this systematic review. Female predominance in IBS prevalence was observed in most studies, while only two studies indicated higher prevalence in males. Key risk factors included family history, anxiety, depression, gastroesophageal reflux disease, low income, diabetes, low water intake, workload, occupation, food allergy, smoking, age, chronic diseases, and stress. IBS prevalence in the Arab world varies significantly. Female predominance was seen in the present systematic review as well.

Abstract
Inflammatory bowel disease is a debilitating condition that undergoes a relapsing and remitting course. The pathogenesis of how this disease manifests remains to be elucidated; however, there is growing evidence that a synergism of familial predisposition and epigenetic alterations influenced by environmental factors all contribute to the development of the disease. The role of nutrition in improving the outcomes of the condition has garnered increasing interest, given the greater risks of neoplastic conversion and concerns about inappropriate remission with available pharmacotherapeutic treatments alone. Available reports, often anecdotal, have documented patient relief with employment of various dietary strategies. These have led to curiosity about nutritional assessments and nutrition therapies to ameliorate the morbidity and all-cause mortality of the disease. One group of such nutrition therapies, supported by a compendium of available articles, is flavonoids-although the greater abundance of in vitro experiments with relatively few clinical trials has limited their clinical use. Nonetheless, flavonoids have been shown to be functional foods with immunomodulatory capabilities. This article will thus delve into the role of flavonoids in altering the course of the immune response in inflammatory bowel disease, while assessing their clinical outcomes in human trials.

Abstract
Background Inflammatory bowel disease (IBD) is a chronic recurrent gastrointestinal inflammatory disease. Selenium has been reported to have therapeutic potential in IBD. Selenium yeast is a common selenium supplement that is convenient to access. This study explored the effect of selenium yeast on dextran sulfate sodium- (DSS-)induced chronic colitis in mice. Methods Mice were randomly divided into four groups: the control group, selenium yeast group, chronic colitis group, and chronic colitis+selenium yeast group (n=6). Mice were killed on the 26th day. The disease activity index (DAI) score and histological damage score were calculated. Cytokines, serum selenium, colonic tissue selenium, gut microbiota and their metabolites short-chain fatty acids (SCFAs) were evaluated. Results Selenium yeast lowered IL-1β, IL-6, TNF-α, IL-17A, IL-22 and IFN-γ (P<0.05). In addition, selenium yeast significantly elevated Turicibacter, Bifidobacterium, Allobaculum, Prevotella, Halomonas, Adlercreutzia (P<0.05), and butyric acid (P<0.05). Conclusion Selenium yeast could improve DSS-induced chronic colitis in mice by regulating cytokines, gut microbiota and their metabolites.

Abstract
Emerging data highlights the heightened risk of atherosclerotic cardiovascular diseases (ASCVD) in patients with chronic inflammatory disorders, particularly those afflicted with inflammatory bowel disease (IBD). This review delves into the epidemiological connections between IBD and ASCVD, elucidating potential underlying mechanisms. Furthermore, it discusses the impact of current IBD treatments on cardiovascular risk. Additionally, the cardiovascular adverse effects of novel small molecule drugs used in moderate-to-severe IBD are investigated, drawing parallels with observations in patients with rheumatoid arthritis. This article aims to comprehensively evaluate the existing evidence supporting these associations. To achieve this, we conducted a meticulous search of PubMed, spanning from inception to August 2023, using a carefully selected set of keywords. The search encompassed topics related to IBD, such as Crohn's disease and ulcerative colitis, as well as ASCVD, including coronary artery disease, cardiovascular disease, atrial fibrillation, heart failure, conduction abnormalities, heart blocks, and premature coronary artery disease. This review encompasses various types of literature, including retrospective and prospective cohort studies, clinical trials, meta-analyses, and relevant guidelines, with the objective of providing a comprehensive overview of this critical intersection of inflammatory bowel disease and cardiovascular health.

Abstract
BACKGROUND AND OBJECTIVES to investigate the association between the dietary nutrient intake and nutritional status of patients with Crohn's disease (CD). METHODS sixty CD patients who had been diagnosed but had not begun treatment were enrolled. The dietary nutrient intake was recorded after three days of 24-hour recall and was calculated using NCCW2006 software. The nutrition levels were assessed using the Patient-Generated Subjective Global Assessment (PG-SGA). Indicators included body mass index (BMI), mid-arm circumference, the circumference of the upper-arm muscle, triceps skinfold thickness, handgrip strength, and the circumference of the lower legs. RESULTS eighty-five per cent of CD patients did not meet the necessary energy requirements. Of these, the protein and dietary fiber intake in 63.33 % and 100 %, respectively, were below the standard of the Chinese dietary reference. Many patients had insufficient intake of vitamins, as well as other macro- and micronutrients. An inverse association was observed between the risk of malnutrition and higher levels of energy (1,590.0-2,070.6 kcal/d, OR = 0.050, 95 % CI: 0.009-0.279) and protein (55.6-70.5 g/d, OR = 0.150, 95 % CI: 0.029-0.773). Appropriate supplementation of vitamin E, calcium, and other dietary nutrients helped to reduce the risk of malnutrition. CONCLUSIONS significant deficiencies in dietary nutrient intake were found in CD patients, and dietary intake was associated with the nutritional status of the patient. Appropriate adjustment and supplementation of nutrient intake may reduce malnutrition risk in CD patients. The gap between actual consumption and recommendation indicates a need for improved nutritional counseling and monitoring. Early relevant advice for the dietary guidance of CD patients may be beneficial for long-term effects associated with nutritional status.

Abstract
Abstract
Background and aim
Malnutrition is a common problem among patients with inflammatory bowel disease and up to 18–62% of ulcerative colitis (UC) patients were reported to be malnourished. This study aimed to assess micronutrient status among naïve UC patients and its correlation with disease severity.
Methods
A prospective case-control study carried out on 46 patients who visited our endoscopy unit between April 2019 and April 2021. The patients were classified into 3 groups of mild, moderate, and severe UC based on colonoscopy findings, and histopathological examination. Serum was collected and assayed for levels of iron, magnesium, zinc, selenium, and copper.
Results
Forty-six (17 male, 29 female) patients divided into 2 groups (23 naïve UC patients and 23 healthy individuals) with the mean age of 32 years were included in the study. The serum levels of magnesium, zinc, and selenium were significantly lower in the UC group (p < 0.001, 0.018 and < 0.001, respectively). However, iron and copper levels were not significantly different between the 2 groups. In discriminating severe from mild-moderate UC cases, there was a statistically significant result of magnesium at cutoff 1.8 or less in discriminating severe from mild to moderate UC cases with an AUC of 0.950 and p value of < 0.001.
Conclusion
Micronutrients should be assessed in patients in UC patients to alert to the fact that correction of these deficiencies could facilitate achievement of remission. Further research is needed to confirm if magnesium levels could serve as a predictor of the disease severity.

Abstract
Inflammatory bowel disease (IBD), Crohn’s disease (CD) and ulcerative colitis (UC) are complex diseases whose etiology is associated with genetic and environmental risk factors, among which are diet and gut microbiota. To date, IBD is an incurable disease and the main goal of its treatment is to reduce symptoms, prevent complications, and improve nutritional status and the quality of life. Patients with IBD usually suffer from nutritional deficiency with imbalances of specific micronutrient levels that contribute to the further deterioration of the disease. Therefore, along with medications usually used for IBD treatment, therapeutic strategies also include the supplementation of micronutrients such as vitamin D, folic acid, iron, and zinc. Micronutrient supplementation tailored according to individual needs could help patients to maintain overall health, avoid the triggering of symptoms, and support remission. The identification of individuals’ genotypes associated with the absorption, transport and metabolism of micronutrients can modify future clinical practice in IBD and enable individualized treatment. This review discusses the personalized approach with respect to genetics related to micronutrients commonly used in inflammatory bowel disease treatment.

Abstract
In recent years, the role of diet in the pathogenesis of inflammatory bowel disease (IBD) has gained great interest within the scientific community. Eating habits from industrialised countries (the so-called western diet or WD) have been associated with a higher incidence of IBD in observational studies, although the dietary factors responsible for the development of the disease are still to be elucidated. Some components of the diet with proinflammatory potential may cause changes in immunity and intestinal microbiota, leading to the inflammatory reaction that causes IBD-related lesions. The quality of available evidence is low, due to methodological issues, such as the lack of intervention studies, small sample size and heterogeneity of studies. For this reason, scientific societies have offered their recommendations using clinical practice guidelines and consensus documents, in order to establish a common criterion in the nutritional treatment of patients with IBD. The objective of this review was to summarise the data published regarding diet in IBD and review the recommendations given by scientific societies.

Abstract
Immune‐mediated diseases (IMDs) are chronic conditions that have an immune‐mediated etiology. Clinically, these diseases appear to be unrelated, but pathogenic pathways have been shown to connect them. While inflammation is a common occurrence in the body, it may either stimulate a favorable immune response to protect against harmful signals or cause illness by damaging cells and tissues. Nanomedicine has tremendous promise for regulating inflammation and treating IMIDs. Various nanoparticles coated with nanotherapeutics have been recently fabricated for effective targeted delivery to inflammatory tissues. RNA interference (RNAi) offers a tremendous genetic approach, particularly if traditional treatments are ineffective against IMDs. In cells, several signaling pathways can be suppressed by using RNAi, which blocks the expression of particular messenger RNAs. Using this molecular approach, the undesirable effects of anti‐inflammatory medications can be reduced. Still, there are many problems with using short‐interfering RNAs (siRNAs) to treat IMDs, including poor localization of the siRNAs in target tissues, unstable gene expression, and quick removal from the blood. Nanotherapeutics have been widely used in designing siRNA‐based carriers because of the restricted therapy options for IMIDs. In this review, we have discussed recent trends in the fabrication of siRNA nanodelivery systems, including lipid‐based siRNA nanocarriers, liposomes, and cationic lipids, stable nucleic acid‐lipid particles, polymeric‐based siRNA nanocarriers, polyethylenimine (PEI)‐based nanosystems, chitosan‐based nanoformulations, inorganic material‐based siRNA nanocarriers, and hybrid‐based delivery systems. We have also introduced novel siRNA‐based nanocarriers to control IMIDs, such as pulmonary inflammation, psoriasis, inflammatory bowel disease, ulcerative colitis, rheumatoid arthritis, etc. This study will pave the way for new avenues of research into the diagnosis and treatment of IMDs.

Abstract
Nowadays, the popularity of snack foods is increasing due to the fast-paced lifestyle of society. Thanks to the prevailing trends related to a healthy lifestyle and organic food, the need to create new products is increasing, but also more and more attention is being paid to high nutritional value. The aim of the study has been to evaluate the energy, nutritional, and health-promoting value of freeze-dried vegetable-based products with hydrocolloids as structure forming additives. The research included mathematical estimation of the energy and nutrients content, as well as selected health-promoting components, such as vitamins and micro- and macro-nutrients. The calculation was based on tabular data of the nutritional values each components of the products. In addition, the quality of the bars has been assessed by means of the daily requirement and the nutritional quality index. The bars have proven to be characterized by high energy and nutritional and health-promoting value. The Index Nutritional Quality (INQ) indicator has shown that the tested products are incorrectly adjusted in terms of the content of nutrients in relation to the energy supplied. The broccoli bar has turned out to be the best option because it has the highest content of protein, fat, and all the relevant vitamins and minerals. Obtained results verified that tested snacks were not enough to cover daily intake of specific nutrients, but introducing such products to balanced diet may have beneficial influence on human health and well-being.

Abstract
Food fortification with bioactive compounds may constitute a way to ameliorate inflammatory bowel diseases (IBDs). Lupin seeds contain an oligomer named deflamin that can reduce IBD’s symptoms via MMP-9 inhibition. Here, our goal was to develop a lupin protein concentrate (LPC) enriched in deflamin and to test its application as a food additive to be used as a functional food against colitis. The nutritional profile of the LPC was evaluated, and its efficacy in vivo was tested, either alone or as added to wheat cookies. The LPC presented high protein and carbohydrate contents (20.09 g/100 g and 62.05/100 g, respectively), as well as antioxidant activity (FRAP: 351.19 mg AAE/10 mg and DPPH: 273.9 mg AAE/10 mg). It was also effective against TNBS-induced colitis in a dose dependent-manner, reducing DAI scores by more than 50% and concomitantly inhibiting MMP-9 activity. When added to cookies, the LPC activities were maintained after baking, and a 4-day diet with LPC cookies induced a significant protective effect against acetic acid-induced colitis, overall bringing lesions, oxidative stress and DNA damage levels to values significantly similar to controls (p < 0.001). The results show that the LPC is an efficient way to deliver deflamin in IBD-targeted diets.

Abstract
Purpose
To gain insight into the behaviors, perceptions and beliefs of inflammatory bowel disease (IBD) patients nutritional and supplementary practices and also to explore perceptions and behaviors in relation to anti-inflammatory supplementation with specific emphasis on Montmorency tart cherries.
Methods
80 IBD patients completed a 16-item close-ended questionnaire which was divided into three sub-sections: baseline/demographic characteristics, disease characteristics and dietary and supplementary perceptions, beliefs and behaviors. One-sample chi-square goodness of fit tests were used for each question and two-way Pearson chi-square tests of independence were used to undertake bivariate cross-tabulation comparisons to test differences in responses to each question between baseline/demographic variables.
Results
The majority of participants (N = 40) did not follow a specific dietary pattern or use supplements (N = 56). Respondents also predominantly rated that diet can both positively (N = 66) and negatively (N = 68) influence IBD. In addition, participants rated that supplements can positively influence IBD (N = 65) and that lack of scientific evidence was the primary mechanism preventing them from utilizing supplements (N = 34). Finally, patients also strongly reported that they would be willing to take Montmorency tart cherry supplementation (N = 73).
Conclusions
The disconnect between behavior and beliefs in both diet and supplementary practices, indicate that interventions designed to translate beliefs/knowledge into behaviors are warranted. There is also a necessity to undertake well-designed intervention trials examining the efficacy of food supplements, and with patient’s willingness to take Montmorency tart cherry, there is a strong rationale for future randomized trials examining the efficacy of tart cherry supplementation in IBD.

Abstract
Intestinal dysbiosis plays a crucial role in the development of inflammatory bowel disease (IBD), including Crohn’s disease (CD) and ulcerative colitis (UC). The importance of bacterial metabolites, such as short-chain fatty acids (SCFAs), succinic and lactic acids, as well as environmental factors that affect their production in the course of IBD, remains unclear. The aim of this study was to evaluate a profile of organic acids in the stool of CD and UC patients with different disease activity. We assessed a correlation between used medications, patient’s diet, and SCFA levels. A total of 35 adult patients were included in the study. We did not observe significant differences in the levels of organic acids between the CD and UC groups, irrespective of disease activity, and a control group. However, propionic acid levels were higher in IBD patients who received trimebutine vs. those who did not (p = 0.031). Higher isobutyric acid levels were observed in patients treated with biological drugs compared with those without such treatment (p = 0.014). No significant correlations were found between organic acid levels and the frequency of dietary fiber consumption. Our results reveal a new link between medication use and organic acid levels in patients with IBD.

Abstract
AIMS To reveal the consistency and discrepancy in the gut microbial structure and function in inflammatory bowel disease (IBD) patients from different regions. METHODS AND RESULTS Gut microbes, antibiotic resistance genes (ARGs) and virulence factors genes (VFGs) were analysed using metagenome data from three cohorts. The abundance of Escherichia coli extensively increased in IBD patients, whereas Subdoligranulum unclassified decreased dramatically in IBD patients from three countries. Escherichia coli showed a positive correlation with multiple ARGs and VFGs in cohorts from China and the United States, including multidrug-related resistance genes and Capsule and LOS-related virulence factors genes. Escherichia coli biofilm synthesis pathways significantly enriched in IBD patients from three different regions. Notably, Subdoligranulum unclassified and Eubacterium hallii were negatively related to ARGs and VFGs. CONCLUSIONS Consistent changes of microbiome structure and function were observed in IBD patients from three different regions. As pathogenic bacteria, E. coli may accelerate IBD progression through encapsulation in biofilms by upregulating antibiotic resistance in Crohn's disease patients. Subdoligranulum unclassified and E. hallii may be beneficial for IBD patients and could serve as potential probiotics for IBD treatment. SIGNIFICANCE AND IMPACT OF THE STUDY This work dispels worries about the regional differences in gut microbial changes in IBD patients and provides useful guidance for more rational microbiome-based therapies.

Abstract
Food allergies are usually managed by food avoidance. Hidden allergens in food, due to cross-contamination and/or allergenic additives added during production, place an important concern in today's increasing food allergy cases worldwide. Previous studies showed that the introduction of unacquainted food components, in an inflamed intestine, results in sensitization to this food. Thus, our aim was to evaluate the kinetics of multiple food allergy induction. Adult male C57BL/6 mice were divided into five groups, four of which were submitted to an intestinal inflammation induction protocol to peanuts. Egg white (OVA) diluted 1:5 v/v in distilled water was instilled by gavage 6h-before (PRIOR), concomitant (AT) and 6h-after (DURING) the onset of the peanut challenge diet. Positive control (POS CONT) and NEG CONT received saline per gavage. Finally, animals were challenged with subcutaneous injections of OVA. Results showed no changes in diet intake were observed. Anti-OVA polyisotypic IgG antibody titers significantly increased in AT. Flow cytometry revealed significant decrease in CD4+CD25+Foxp3+ and significant increase in TCD8+ in AT. Histomorphometrically, AT and DURING were classified as Infiltrative and Partial Destruction stages. PRIOR was classified as Infiltrative, while POS CONT was classified as Partial Destruction. NEG CONT was classified as Normal. Together, our results confirm that the introduction of unfamiliar food only a few hours before the initiation of a gut inflammation process is able to induce oral tolerance, however the introduction of a dietary protein concomitant to the onset or during an ongoing gut inflammation may induce multiple allergies.

Abstract
Leptin is a pluripotent peptide hormone produced mainly by adipocytes, as well as by other tissues such as the stomach. Leptin primarily acts on the central nervous system, particularly the hypothalamus, where this hormone regulates energy homeostasis and neuroendocrine function. Owing to this, disruption of leptin signaling has been linked with numerous pathological conditions. Recent studies have also highlighted the diverse roles of leptin in the digestive system including immune regulation, cell proliferation, tissue healing, and glucose metabolism. Of note, leptin acts differently under physiological and pathological conditions. Here, we review the current knowledge on the functions of leptin and its downstream signaling in the gastrointestinal tract and accessory digestive organs, with an emphasis on its physiological and pathological implications. We also discuss the current therapeutic uses of recombinant leptin, as well as its limitations.

Abstract
BACKGROUND One goal of multi-omic studies is to identify interpretable predictive models for outcomes of interest, with analytes drawn from multiple omes. Such findings could support refined biological insight and hypothesis generation. However, standard analytical approaches are not designed to be "ome aware." Thus, some researchers analyze data from one ome at a time, and then combine predictions across omes. Others resort to correlation studies, cataloging pairwise relationships, but lacking an obvious approach for cohesive and interpretable summaries of these catalogs. METHODS We present a novel workflow for building predictive regression models from network neighborhoods in multi-omic networks. First, we generate pairwise regression models across all pairs of analytes from all omes, encoding the resulting "top table" of relationships in a network. Then, we build predictive logistic regression models using the analytes in network neighborhoods of interest. We call this method CANTARE (Consolidated Analysis of Network Topology And Regression Elements). RESULTS We applied CANTARE to previously published data from healthy controls and patients with inflammatory bowel disease (IBD) consisting of three omes: gut microbiome, metabolomics, and microbial-derived enzymes. We identified 8 unique predictive models with AUC > 0.90. The number of predictors in these models ranged from 3 to 13. We compare the results of CANTARE to random forests and elastic-net penalized regressions, analyzing AUC, predictions, and predictors. CANTARE AUC values were competitive with those generated by random forests and penalized regressions. The top 3 CANTARE models had a greater dynamic range of predicted probabilities than did random forests and penalized regressions (p-value = 1.35 × 10-5). CANTARE models were significantly more likely to prioritize predictors from multiple omes than were the alternatives (p-value = 0.005). We also showed that predictive models from a network based on pairwise models with an interaction term for IBD have higher AUC than predictive models built from a correlation network (p-value = 0.016). R scripts and a CANTARE User's Guide are available at https://sourceforge.net/projects/cytomelodics/files/CANTARE/ . CONCLUSION CANTARE offers a flexible approach for building parsimonious, interpretable multi-omic models. These models yield quantitative and directional effect sizes for predictors and support the generation of hypotheses for follow-up investigation.

Abstract
Inflammatory bowel disease (IBD) is a non-communicable disease characterized by a chronic inflammatory process of the gut and categorized into Crohn’s disease and ulcerative colitis, both currently without definitive pharmacological treatment and cure. The unclear etiology of IBD is a limiting factor for the development of new drugs and explains the high frequency of refractory patients to current drugs, which are also related to various adverse effects, mainly after long-term use. Dissatisfaction with current therapies has promoted an increased interest in new pharmacological approaches using natural products. Coumarins comprise a large class of natural phenolic compounds found in fungi, bacteria, and plants. Coumarin and its derivatives have been reported as antioxidant and anti-inflammatory compounds, potentially useful as complementary therapy of the IBD. These compounds produce protective effects in intestinal inflammation through different mechanisms and signaling pathways, mainly modulating immune and inflammatory responses, and protecting against oxidative stress, a central factor for IBD development. In this review, we described the main coumarin derivatives reported as intestinal anti-inflammatory products and its available pharmacodynamic data that support the protective effects of these products in the acute and subchronic phase of intestinal inflammation.

Abstract
Recent research studies have shown that vitamin C (ascorbic acid) may affect bone mineral density and that a deficiency of ascorbic acid leads to the development of osteoporosis. Patients suffering from an inflammatory bowel disease are at a risk of low bone mineral density. It is vital to notice that patients with Crohn’s disease and ulcerative colitis also are at risk of vitamin C deficiency which is due to factors such as reduced consumption of fresh vegetables and fruits, i.e., the main sources of ascorbic acid. Additionally, some patients follow diets which may provide an insufficient amount of vitamin C. Moreover, serum vitamin C level also is dependent on genetic factors, such as SLC23A1 and SLC23A2 genes, encoding sodium-dependent vitamin C transporters and GSTM1, GSTP1 and GSTT1 genes which encode glutathione S-transferases. Furthermore, ascorbic acid may modify the composition of gut microbiota which plays a role in the pathogenesis of an inflammatory bowel disease.
