Heliyon 2024; 10:e24875. [PMID: 38312708 PMCID: PMC10835364 DOI: 10.1016/j.heliyon.2024.e24875] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/24/2023] [Revised: 01/15/2024] [Accepted: 01/16/2024] [Indexed: 02/06/2024] Open
Abstract
Ulcerative colitis (UC) is a refractory inflammatory disease with imbalances in intestinal mucosal homeostasis. Cuproptosis serves as newly identified programmed cell death (PCD) form involved in UC. In the study, UC-related datasets were extracted from the Gene Expression Omnibus (GEO) database. A comparison of UC patients and healthy controls identified 11 differentially expressed cuproptosis-related genes (DE-CRGs), where FDX1, LIAS, and DLAT were differentially expressed in UC groups from the mouse models and clinical samples, with their expression correlating with disease severity. By comprehending weighted gene co-expression network analysis (WGCNA) and differential expression analysis, the key genes common to the module genes relevant to different cuproptosis-related clusters and differentially expressed genes (DEGs) both in different clusters and patients with and without UC were identified using several bioinformatic analysis. Furthermore, the mRNA levels of four characteristic genes with diagnostic potential demonstrated significant decrease in both mouse models and clinical UC samples. Our discoveries offer a theoretical foundation for cuproptosis effect in UC.

Chao HC. Zinc Deficiency and Therapeutic Value of Zinc Supplementation in Pediatric Gastrointestinal Diseases. Nutrients 2023; 15:4093. [PMID: 37836377 PMCID: PMC10574543 DOI: 10.3390/nu15194093] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/13/2023] [Revised: 09/11/2023] [Accepted: 09/19/2023] [Indexed: 10/15/2023] Open
Abstract
The benefits of zinc in treating certain gastrointestinal (GI) diseases have been recognized for over two decades. This review aims to explore zinc deficiency (ZD) and the potential therapeutic value and safety of zinc supplementation in pediatric GI diseases. A systematic review of published articles on ZD and zinc as adjuvant treatments for GI diseases was conducted using various databases. Children with inflammatory bowel disease (IBD), celiac disease, and those receiving long-term proton pump inhibitor treatments are particularly susceptible to ZD. ZD in children with celiac disease and IBD is attributed to insufficient intake, reduced absorption, and increased intestinal loss as a result of the inflammatory process. Zinc plays a crucial role in maintaining the integrity of the gastric mucosa and exerts a gastroprotective action against gastric lesions. Although considerable evidence supports the use of zinc as adjuvant therapy for certain GI diseases in adults, its use is unspecified in children except for infectious diarrhea. Current evidence suggests that zinc supplementation with well-documented dosages helps reduce the duration of diarrhea in children with acute or persistent diarrhea, while there are no specific guidelines for zinc supplementation in children with IBD and celiac disease. Zinc supplementation appears to be beneficial in peptic ulcer disease or gastroesophageal reflux disease. The available evidence highlights the need for intervention programs to enhance zinc status and reduce the morbidity of certain GI diseases in children.

Abstract
Inflammatory bowel disease (IBD) is an autoimmune intestinal disease that includes ulcerative colitis, Crohn's disease, and indeterminate colitis. Patients with IBD are often at risk for malnutrition, including micronutrient deficiencies, due to dietary restrictions and poor intestinal absorption. Micronutrients, including vitamins and minerals, play an important role in the human body's metabolism and maintenance of tissue functions. This article reviews the role of micronutrients in IBD. Micronutrients can affect the occurrence and progression of IBD by regulating immunity, intestinal flora, oxidative stress, intestinal barrier function, and other aspects. Monitoring and timely supplementation of micronutrients are important to delay progression and improve clinical symptoms in IBD patients.

Abstract
BACKGROUND AND AIMS Micronutrient deficiencies are common in patients with inflammatory bowel disease (IBD), but whether they relate to disease outcomes remains unknown. This study assessed the micronutrient status of adults with IBD on treatment with biologic therapies and explored predictive relationships with disease outcomes. METHODS Seventeen micronutrients were measured in the blood of 216 adults with IBD on biologic therapy. Of these, 127 patients (58%) had Crohn's disease (CD), and the majority (70%) received treatment with infliximab. Patients were followed for 12 months and onset of adverse clinical outcomes (eg, requirement for treatment with corticosteroids, hospitalization, or surgical intervention) was recorded, and related to micronutrient status. RESULTS Among all patients, the most common deficiencies were for vitamin C (n = 35 of 212 [16.5%]), ferritin (n = 27 of 189 [14.3%]), folate (n = 24 of 171 [14.0%]), and zinc (n = 27 of 210 [12.9%]). During follow-up, 22 (10%) of the 216 patients developed 1 or more adverse clinical outcomes. Patients with CD and zinc deficiency were significantly more likely to require surgery (P = .002) or treatment with corticosteroids (P < .001). In contrast, patients with ulcerative colitis and selenium deficiency were significantly more likely to have a clinical flare of disease (P = .001), whereas those with CD were not. This relationship with selenium remained significant after adjustment for confounders. CONCLUSIONS A substantial proportion of adults with IBD present deficiencies for certain micronutrients, with selenium and zinc deficiency predicting adverse disease outcomes. For other micronutrients, deficiencies were less common and should not warrant routine screening. Intervention studies should explore the effect of micronutrient supplementation in modifying disease outcomes in IBD.

Abstract
INTRODUCTION Inflammatory bowel disease (IBD) develops through complex interplay of genetic, microbial, immune, and environmental factors. Trace elements alterations are commonly present in IBD and may have influence on IBD development. Heavy metal pollution is one of the major environmental issues nowadays and IBD incidence is rising in countries where industry starts to develop. Metals are implicated in processes that are connected to IBD pathogenesis. AIM The aim of this study was to investigate toxic and trace element levels in pediatric population of IBD patients both in serum and intestinal mucosa. MATERIALS AND METHODS This prospective study enrolled children newly diagnosed with IBD in University children's hospital in Belgrade. Concentrations of thirteen elements: Al, As, Ca, Cd, Cr, Cu, Fe, K, Mg, Mn, Na, Se and Zn in serum and intestinal mucosa of 17 newly diagnosed children with IBD (10 Crohn's disease (CD) and 7ulcerative colitis (UC)) and 10 controls were assessed using inductively coupled plasma mass spectrometry (ICP-MS). Intestinal mucosa samples were taken from terminal ileum and six different colon segments (cecum, ascending colon, colon transversum, descending and sigmoid colon and rectum). RESULTS The results demonstrated significant alterations in serum and intestinal mucosa concentrations of investigated elements. Serum iron was significantly decreased in IBD and CD group, compared to controls while serum Cu significantly differed between three investigated groups with highest concentration observed in CD children. Serum manganese was the highest in the UC subgroup. Terminal ileums of IBD patients contained significantly lower amount of Cu, Mg, Mn and Zn with Mn being significantly decreased also in CD patients compared to control. IBD patients' caecum contained significantly less Mg and Cu while colon transversum tissue samples from IBD and Crohn's patients contained significantly more chromium than controls. Moreover, sigmoid colon of IBD patients were poorer in Mg than controls (p < 0.05). Colon Al, As and Cd were significantly reduced in IBD, and UC children compared to control. Correlations of investigated elements in CD and UC groups were different from controls. Biochemical and clinical parameters showed correlation with element concentrations in intestines. CONCLUSION Sera of CD, UC and control children significantly differ in Fe, Cu and Mn levels. Serum manganese was the highest in the UC subgroup creating the most prominent and only significant difference between UC and CD subgroups. Terminal ileum of IBD patients contained significantly lower amount of majority of investigated essential trace elements and toxic elements were significantly reduced in colon of IBD and UC patients. Investigation of macro- and microelement alterations in children and adults has potential to further elucidate IBD pathogenesis.

ENVIRONMENTAL SCIENCE AND POLLUTION RESEARCH INTERNATIONAL 2023; 30:66486-66493.

Abstract
The relationship between heavy metals and ulcerative colitis (UC) was investigated in several studies, but their results were not consistent. Therefore, in this systematic review study, the positive and negative effects of metal(loid)s (Zn, Cu, Fe, Se, Pb, Ni, and As) on UC disease were investigated. In this systematic search, 13 original articles from 1993 to 2021 were identified in Google Scholar, Science Direct, Scopus, PubMed, and the Web of Science databases. In included studies, the concentrations of heavy metals and essential elements were measured in the blood, serum, intestinal biopsies, and hair samples of the patients. Some studies have also examined the heavy metal concentration in UC patients' diet and their drinking water. In the serum samples, Pb (220 ± 108 mg/L) and Cu (401.5 ± 104 µg/L) had the maximum concentrations among the other elements, as well as Zn and Fe had the highest levels in hair and intestinal tissue samples, respectively. In light of the selected articles, there is a possibility of a preventive role for Se and Zn in UC development. Moreover, exposure to Fe can exacerbate the symptoms of the disease. In conclusion, this review reveals that toxic metals, as ubiquitous environmental pollutants, can contribute to the exacerbation of inflammatory intestinal symptoms, and consumption of essential elements can play a vital role in the control of UC, and it is important to pay attention to them in health decisions.

Abstract
Malnutrition is an important issue in patients with inflammatory bowel diseases (IBDs) including Crohn's disease (CD) and ulcerative colitis (UC). It is caused by altered digestion and absorption within the small bowel, inadequate food intake, and drug-nutrient interactions in patients. Malnutrition is an essential problem because it is related to an increased risk of infections and poor prognosis in patients. It is known that malnutrition is also related to an increased risk of postsurgery complications in IBD patients. Basic nutritional screening involves anthropometric parameters with body mass index (BMI) and others (fat mass, waist-to-hip ratio, muscle strength), medical history concerning weight loss, and biochemical parameters (including the Prognostic Nutritional Index). Besides standard nutritional screening tools, including the Subjective Global Assessment (SGA), Nutritional Risk Score 2002 (NRS 2002), and Malnutrition Universal Screening Tool (MUST), specific nutritional screening tools are used in IBD patients, such as the Saskatchewan Inflammatory Bowel Disease-Nutrition Risk Tool (SaskIBD-NR Tool and IBD-specific Nutritional Screening Tool). There is a higher risk of nutrient deficiencies (including iron, zinc, magnesium) and vitamin deficiencies (including folic acid, vitamin B12 and D) in IBD patients. Therefore, regular evaluation of nutritional status is important in IBD patients because many of them are undernourished. An association between plasma ghrelin and leptin and nutritional status in IBD patients has been observed. According to some authors, anti-tumor necrosis factor (anti-TNFα) therapy (infliximab) can improve nutritional status in IBD patients. On the other hand, improvement in nutritional status may increase the response rate to infliximab therapy in CD patients. Optimization of nutritional parameters is necessary to improve results of conservative and surgical treatment and to prevent postoperative complications in patients with IBDs. This review presents basic nutritional screening tools, anthropometric and laboratory parameters, dietary risk factors for IBDs, common nutrient deficiencies, associations between anti-TNFα therapy and nutritional status, selected features regarding the influence of nutritional status, and surgical outcome in IBD patients.

Abstract
Ulcerative colitis (UC) is an idiopathic, chronic and relapsing colonic inflammatory disease. Despite the involvement of diverse intricate mechanisms, COX mediated inflammatory pathway is crucial in the pathophysiology of colitis. Thus, COX inhibition is imperative for managing colitis-associated inflammation. However, the use of COX inhibitory classical non-steroidal anti-inflammatory drugs (NSAIDs) for inflammation resolution has been linked to sudden increased flare-ups. Therefore, considering the anti-inflammatory and pro-resolution effects of antioxidant and essential trace element Selenium (Se), a Seleno-derivative of Celecoxib called Selenocoxib-3 was characterized and evaluated for its favourable pharmacokinetics, safety margins and anti-inflammatory therapeutic potential in DSS-induced experimental colitis. The serum pharmacokinetic profiling [elimination rate constant (K) and clearance (Cl) and toxicity profiling suggested enhanced efficacy, therapeutic potential and lesser toxicity of Selenocoxib-3 as compared to its parent NSAID Celecoxib. In vivo studies demonstrated that Selenocoxib-3 efficiently resolves the gross morphological signs of DSS-induced colitis such as diarrhoea, bloody stools, weight loss and colon shortening. Further, intestinal damage evaluated by H & E staining and MPO activity suggested of histopathological disruptions, such as neutrophil infiltration, mucodepletion and cryptitis, by Selenocoxib-3. The expression profiles of COX-1/2 demonstrated mitigation of pro-inflammatory mediators thereby promoting anti-inflammatory efficacy of Selenocoxib-3 when compared with Celecoxib. The current study suggests translational applicability of Se-containing novel class of COX inhibitors for efficiently managing inflammatory disorders such as UC.

Abstract
BACKGROUND Despite increased awareness of diet and nutrition being integral to the management of patients with inflammatory bowel disease (IBD), there are gaps in the knowledge of IBD healthcare providers regarding nutrition. Furthermore, high quality evidence on nutritional assessment and dietary management of IBD is limited. A Delphi consensus from a panel of experts allows for best-practice guidelines to be developed, especially where high quality evidence is limited. The aim was to develop guidelines for the nutritional assessment and dietary management of IBD using an eDelphi online consensus agreement platform. METHODS Seventeen research topics related to IBD and nutrition were systematically reviewed. Searches in Cochrane, Embase®, Medline® and Scopus® electronic databases were performed. GRADE was used to develop recommendations. Experts from the IBD community (healthcare professionals and patients with IBD) were invited to vote anonymously on the recommendations in a custom-built online platform. Three rounds of voting were carried out with updated iterations of the recommendations and evaluative text based on feedback from the previous round. RESULTS From 23,824 non-duplicated papers, 167 were critically appraised. Fifty-five participants completed three rounds of voting and 14 GRADE statements and 42 practice statements achieved 80% consensus. Comprehensive guidance related to nutrition assessment, nutrition screening and dietary management is provided. CONCLUSIONS Guidelines on the nutritional assessment and dietary management of IBD have been developed using evidence-based consensus to improve equality of care. The statements and practice statements developed demonstrate the level of agreement and the quality and strength of the guidelines.

Abstract
Background Ulcerative colitis (UC) is a chronic and debilitating inflammatory bowel disease that impairs quality of life. Cuproptosis, a recently discovered form of cell death, has been linked to many inflammatory diseases, including UC. This study aimed to examine the biological and clinical significance of cuproptosis-related genes in UC. Methods Three gene expression profiles of UC were obtained from the Gene Expression Omnibus (GEO) database to form the combined dataset. Differential analysis was performed based on the combined dataset to identify differentially expressed genes, which were intersected with cuproptosis-related genes to obtain differentially expressed cuproptosis-related genes (DECRGs). Machine learning was conducted based on DECRGs to identify signature genes. The prediction model of UC was established using signature genes, and the molecular subtypes related to cuproptosis of UC were identified. Functional enrichment analysis and immune infiltration analysis were used to evaluate the biological characteristics and immune infiltration landscape of signature genes and molecular subtypes. Results Seven signature genes (ABCB1, AQP1, BACE1, CA3, COX5A, DAPK2, and LDHD) were identified through the machine learning algorithms, and the nomogram built from these genes had excellent predictive performance. The 298 UC samples were divided into two subtypes through consensus cluster analysis. The results of the functional enrichment analysis and immune infiltration analysis revealed significant differences in gene expression patterns, biological functions, and enrichment pathways between the cuproptosis-related molecular subtypes of UC. The immune infiltration analysis also showed that the immune cell infiltration in cluster A was significantly higher than that of cluster B, and six of the characteristic genes (excluding BACE1) had higher expression levels in subtype B than in subtype A. Conclusions This study identified several promising signature genes and developed a nomogram with strong predictive capabilities. The identification of distinct subtypes of UC enhances our current understanding of UC's underlying pathogenesis and provides a foundation for personalized diagnosis and treatment in the future.

Abstract
Background Crohn's disease (CD) is a type of heterogeneous, dysfunctional immune-mediated intestinal chronic and recurrent inflammation caused by a variety of etiologies. Cuproptosis is a newly discovered form of programmed cell death that seems to contribute to the advancement of a variety of illnesses. Consequently, the major purpose of our research was to examine the role of cuproptosis-related genes in CD. Methods We obtained two CD datasets from the gene expression omnibus (GEO) database, and immune cell infiltration was created to investigate immune cell dysregulation in CD. Based on differentially expressed genes (DEGs) and the cuproptosis gene set, differentially expressed genes of cuproptosis (CuDEGs) were found. Then, candidate hub cuproptosis-associated genes were found using machine learning methods. Subsequently, using 437 CD samples, we explored two distinct subclusters based on hub cuproptosis-related genes. Gene Ontology (GO), Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment, Gene set variation analysis (GSVA) and immune infiltration analysis studies were also used to assess the distinct roles of the subclusters. Results Overall, 25 CuDEGs were identified, including ABCB6, BACE1, FDX1, GLS, LIAS, MT1M, PDHA1, etc. And most CuDEGs were expressed at lower levels in CD samples and were negatively related to immune cell infiltration. Through the machine learning algorithms, a seven gene cuproptosis-signature was identified and two cuproptosis-related subclusters were defined. Cluster-specific differentially expressed genes were found only in one cluster, and functional analysis revealed that they were involved in several immune response processes. And the results of GSVA showed positive significant enrichment in immune-related pathways in cluster A, while positive significant enrichment in metabolic pathways in cluster B. In addition, an immune infiltration study indicated substantial variation in immunity across different groups. Immunological scores were higher and immune infiltration was more prevalent in Cluster A. Conclusion According to the current research, the cuproptosis phenomenon occurs in CD and is correlated with immune cell infiltration and metabolic activity. This information indicates that cuproptosis may promote CD progression by inducing immunological response and metabolic dysfunction. This research has opened new avenues for investigating the causes of CD and developing potential therapeutic targets for the disease.

Abstract
Objectives Cuproptosis is a recently discovered form of programmed cell death; however, its role in ulcerative colitis (UC) remains a void. Methods Three gene expression profiles were acquired from the GEO database. Subsequently, the single sample gene set enrichment analysis (ssGSEA) was performed to identify the immune infiltration characteristics of UC. Correlation analysis between cuproptosis and immune infiltration was further conducted, and the cuproptosis-related genes were applied to construct a UC diagnostic model. Subsequently, analysis results of microarray data were experimentally validated by DSS-induced colitis in mice. Finally, therapeutic agents for the cuproptosis-related genes were screened owing to the gaping field of therapeutic agents on cuproptosis. Results Three gene expression profiles with 343 samples (290 UC and 53 healthy samples) were included. Immune infiltration revealed that UC patients had a higher level of DCs, B cells, CD8+ T cells, iDCs, Macrophages, neutrophils, pDCs, T helper cells, Tfh, Th1 cells, Th2 cells, TIL and Treg than normal subjects. Moreover, almost all cuproptosis-related genes were significantly negatively associated with immune infiltration in UC patients. The risk prediction model based on cuproptosis-related genes showed an excellent discrimination for UC. Animal experiments revealed significant alterations in genes essential for cuproptosis between DSS-induced colitis mice and healthy controls, providing experimental validation for the analysis results of microarray data. Further analysis revealed that latamoxef, vitinoin, clomipramine, chlorzoxazone, glibenclamide, pyruvic acid, clindamycin, medrysone, caspan, and flavin adenine dinucleotide might be the target agents for cuproptosis-related genes. Conclusions In conclusion, cuproptosis was significantly associated with immune infiltration in UC, and the cuproptosis-related genes showed an excellent discrimination for UC.

Abstract
BACKGROUND Reports of zinc and selenium deficiencies accompanying inflammatory bowel disease (IBD) mostly have originated from Western countries and concerned adult patients. Whether Japanese children with IBD have similar deficiencies remained unclear. AIM We aimed to elucidate differences in serum zinc and selenium concentrations in Japanese children between types of IBD. METHODS Children under 17 years old undergoing care at 12 Japanese pediatric centers were retrospectively enrolled between November 2016 and February 2018 to 3 groups representing Crohn's disease (CD), ulcerative colitis (UC), and normal controls (NC) with irritable bowel syndrome or no illnesses. Serum zinc and selenium were measured by atomic absorption spectrophotometry. Zinc and selenium deficiencies were defined by serum concentrations < 70 μg/dL and < 9.5 μg/dL, respectively. RESULTS Subjects included 98 patients with CD (median age, 13 years), 118 with UC (11 years), and 43 NC (11 years). Serum zinc and selenium were significantly lower in CD (median, 64 and 12.6 μg/dL respectively) than in UC (69 and 14.6; P < 0.05 and P < 0.001) or NC (77 and 15.7; P < 0.01 and P < 0.001). Zinc deficiency was significantly more prevalent in CD (60.2%) than in NC (37.2%; P < 0.05), but not than in UC (51.7%; P = 0.22). Selenium deficiency was significantly more prevalent in CD (15.3%) than in UC (5.9%; P < 0.05) or NC (0%; P < 0.01). CONCLUSIONS In Japanese children under 17 years old, serum zinc and selenium were significantly lower in CD than in UC or NC. Zinc and selenium should be monitored, and supplemented when deficient, in children with IBD, especially CD.

Abstract
Microelements represent an emerging resource for medicine and its preventive branch. Zinc is the second most abundant element in our organism with peculiar physiologic functions and pathophysiologic implications in systemic and gastrointestinal (GI) diseases. It interacts very often with gut microbiota (GM) and can affect natural course of GI diseases through a bidirectional relationship with intestinal bugs. We aimed to review literature data regarding zinc chemistry, role in health, and GI diseases in man with a special focus on its interaction with GM. We conducted a search on the main medical databases for original articles, reviews, meta-analyses, randomized clinical trials and case series using the following keywords and acronyms and their associations: zinc, microelements, gut microbiota, gut health, and COVID-19. Zinc has a rapid and simple metabolism and limited storage within our body. Its efficacy on immune system modulation reflects on improved response to pathogens, reduced inflammatory response, and improved atopic/allergic reactions. Zinc is also involved in cell cycle regulation (namely, apoptosis) with potential anti-cancerogenic effects. All these effects are in a "symbiotic" relationship with GM. Finally, zinc shows preliminary viral antireplicative effects. Zinc seems to gain more and more evidences on its efficacy in allergic, atopic and infectious diseases treatment, and prevention. COVID-19 can be the booster for research on future applications of zinc as perfect "postbiotic" in medicine.

Abstract
The deficiency of selenium has been found in clinical IBD patients and supplementation selenium is recognized as beneficial for colitis treatment. In this study, an organic selenium compound-selenylation α-D-1,6-glucan (sCPA) was prepared, and the effect of sCPA on DSS induced colitis mice was investigated. The results suggested that sCPA prevented the weight loss, colon length shortening, and stool loose of colitis mice. It protected colon mucosal barrier by promoting tight junction protein ZO-1 and Occludin expression. Moreover, sCPA reduced oxidative stress via regulating SOD and MDA levels, and decreased the contents of inflammatory proteins NF-κB and NLRP3 and adjusted TNF-α, IFN-γ, IL-1β, and IL-10 inflammatory cytokines. Furthermore, sCPA repaired intestinal microbiota composition especially Bacteroidetes, Firmicutes, Proteobacteria, and Actinobacteria that altered by DSS in colitis mice. Meanwhile, SCFAs produced by gut microbiota were restored by sCPA close to the level in the normal group. In conclusion, these findings indicated that the sCPA might be a potential dietary selenium supplementation for the prevention and treatment of colitis.

Biol Trace Elem Res 2021; 199:2543-2551.

Abstract
The associations between copper and zinc intake with the risk of inflammatory bowel disease (IBD) and fecal incontinence symptoms in the general population are not well understood. This study aims to evaluate the associations of zinc and copper intake with the risk of IBD and fecal incontinence symptoms in adults aged ≥ 20 years using data from the 2009-2010 National Health and Nutritional Examination Surveys (NHANES) (N = 5593). The presence of IBD was analyzed from the NHANES data, directly querying the presence or absence of ulcerative colitis (UC) and Crohn's disease (CD). Fecal incontinence symptoms including accidental bowel leakage of gas, mucus, liquid, or solid stool were determined by using the bowel health questionnaire. Multivariable logistic regressions models were performed controlling for confounding factors (dietary, lifestyle, psychological, and health conditions). No associations between either zinc or copper intake with IBD were found. However, zinc intake was independently associated with increased risk of bowel leakage of gas or liquid. Compared with quartile 1, the multivariate-adjusted ORs (95%CI) of bowel leakage of gas across quartiles 2-4 of zinc intake were 1.41 (1.15-1.71), 1.30 (1.00-1.68), and 1.61 (1.16-2.23). Likewise, there was a trend for higher odds of bowel leakage of liquid among participants in the higher zinc intake. Compared with quartile 1, the multivariate-adjusted ORs (95%CI) of bowel leakage of liquid across quartiles 2-4 of zinc intake were 3.55 (0.94-13.41), 3.65 (1.27-10.47), and 5.06 (1.25-20.50). Future prospective studies are warranted to confirm these findings.

Abstract
OBJECTIVE Observational epidemiologic studies have reported a relationship between selenium status and risk for autoimmune diseases. However, the associations are susceptible to confounding or reverse causality. Thus, the aim of this study was to investigate the potential causal associations of selenium concentrations with the risk for common autoimmune diseases using a two-sample Mendelian randomization (MR) design. METHODS A meta-analysis of genome-wide association studies (GWASs) of selenium among 9639 individuals of European ancestry was used to identify genetic instruments. Summary statistics of systemic lupus erythematosus, rheumatoid arthritis, and inflammatory bowel disease were obtained from publicly available GWASs, respectively. We conducted MR study using the inverse-variance weighted method, supplemented with weighted median and likelihood-based methods as sensitivity analysis. Cochran Q test and MR-Egger regression were used to detect heterogeneity and potential directional pleiotropy. MR-Pleiotropy RESidual Sum and Outlier test was used to identify outlier single-nucleotide polymorphisms. RESULTS Genetically predicted high selenium level was associated with a decreased risk for SLE (odds ratio, 0.85; 95% confidence interval, 0.77-0.93; P = 0.001) per natural log-transformed selenium concentrations, with similar results in sensitivity analyses. No evidence of heterogeneity, pleiotropy, or outlier single-nucleotide polymorphisms were detected (all P > 0.05). However, genetically determined selenium concentrations may be not associated with risk for rheumatoid arthritis or inflammatory bowel disease in the primary analysis and subsequent sensitivity analyses. CONCLUSIONS The present study suggested a protective role of selenium on the risk for systemic lupus erythematosus. Further studies are warranted to elucidate the underlying mechanisms.

Abstract
Management of inflammatory bowel disease (IBD) has always been a challenge for physicians. Current treatment protocols may cause numerous adverse effects. Selenium is known for its putative antiinflammatory properties. Selenium is needed for the biosynthesis of enzymatically active selenoproteins, which contribute to antioxidative defense, and effective function of immune systems. Several studies have shown that patients with IBD have a lower selenium level compared to healthy subjects. Hence, experimental studies mimicking ulcerative colitis and Crohn's disease investigated the effect of selenium supplementation on IBD. Previous studies indicated the following: 1) Selenoproteins can curb the inflammatory response and attenuate oxidative stress. This antiinflammatory property caused remission in animal models of colitis. 2) Selenium supports protective gut microbiota, which indirectly improves management of IBD. 3) Selenium may block some of the predominant tumorigenesis pathways proposed in colitis-associated colorectal cancer. 4) Selenium supplementation showed promising results in preliminary clinical studies, particularly in patients with selenium deficiency. While selenium supplementation seems to be beneficial for IBD, clinical studies have remained too preliminary in this regard. Randomized clinical trials are needed to measure the short-term and long-term effects of selenium on both active and quiescent IBD, particularly in patients with IBD who have documented selenium deficiency.

Abstract
Concentrations of 16 metals in the scalp hair of male Crohn's disease (CD) patients (n = 28) were compared to those of male control subjects (n = 25). The majority of patients (n = 20) took an anti-inflammatory agent (mesalazine), and several patients underwent colectomy. A low concentration of serum ferritin was observed in approximately 50% of CD patients due to Fe-deficiency anemia. The concentrations of Fe, Cr, and Co in the hair of CD patients were significantly higher than those of control subjects, and particularly high concentrations were found in CD patients with low serum ferritin. Significant correlations were found among the concentrations of Fe, Cr, and Co in the hair of CD patients, but not in control subjects. In agreement with previous reports, a significant negative correlation was found between ferritin and transferrin concentrations in serum, although the available data in this study was limited (n = 8). Transferrin not only binds to Fe3+ but also to Cr3+ and Co3+, and the amount of transferrin is increased in Fe-deficiency anemia. Thus, the majority of the Fe3+, Cr3+, and Co3+ in the serum of CD patients is likely to bind to transferrin, which may be associated with the higher concentrations of those metals, as well as the significant correlations among those metals in the scalp hair of CD patients. In addition, colectomy may alter the intestinal absorption rate of some metals, while mesalazine may increase the concentrations of Mn and some metals in the scalp hair by chelate formation.

Abstract
The chronic character of inflammatory bowel diseases, such as Crohn's disease and ulcerative colitis, results in various complications. One of them is osteoporosis, manifested by low bone mineral density, which leads to an increased risk of fractures. The aetiology of low bone mineral density is multifactorial and includes both diet and nutritional status. Calcium and vitamin D are the most often discussed nutrients with regard to bone mineral density. Moreover, vitamins A, K, C, B12; folic acid; calcium; phosphorus; magnesium; sodium; zinc; copper; and selenium are also involved in the formation of bone mass. Patients suffering from inflammatory bowel diseases frequently consume inadequate amounts of the aforementioned minerals and vitamins or their absorption is disturbed, resulting innutritional deficiency and an increased risk of osteoporosis. Thus, nutritional guidelines for inflammatory bowel disease patients should comprise information concerning the prevention of osteoporosis.

Abstract
BACKGROUND Zinc (Zn) and copper (Cu) are trace elements that serve as cofactors in catalytic processes with impact on immune responses. In patients with inflammatory bowel disease (IBD), decreased levels of serum Zn and Cu have been observed. Here, we investigated the effect of inflammation on serum concentrations of these trace elements in patients with IBD. METHODS In this cross-sectional study, 98 patients with Crohn disease (CD) and 56 with ulcerative colitis (UC) were prospectively enrolled. Disease activity parameters, such as C-reactive protein (CRP) and fecal calprotectin (FC) were compared to serum Zn, Cu, and Cu/Zn ratio. RESULTS Zinc insufficiency was observed in 11.2% of patients with CD and 14.3% with UC, Cu insufficiency in 20.4% with CD and 7.1% with UC. Anemia, hypoalbuminemia, increased FC, and elevated CRP were more frequently present in Zn-insufficient patients with IBD. In contrast, lower serum CRP values and a trend to lower FC were observed in Cu-insufficient patients. In multiple linear regression models adjusted for age, gender, and serum albumin, CRP positively correlated with serum Cu (P < 0.001) and the Cu/Zn ratio in both CD and UC (P < 0.001) but not with serum Zn concentrations. FC levels correlated only with the Cu/Zn ratio in patients with UC (P < 0.038). CONCLUSION Systemic inflammation inversely affected the serum Zn and Cu concentrations and, consequently, resulted in an increased Cu/Zn ratio.

Abstract
INTRODUCTION Inflammatory bowel disease (IBD), a chronic inflammatory disorder of gastrointestinal tract, arises from complex interaction between genetics, environment, gut microbiota and mucosal immune response. Along with clinical, endoscopic and radiological evaluation various biomarkers are needed as an additional diagnostic tool, as well as to predict disease course and therapeutic outcomes. AIM The aim of this study was to evaluate clinical value of essential trace elements (ETEs) serum concentration profile in the assessment of pediatric IBD diseases development. MATERIALS AND METHODS Concentration of five ETEs: iron (Fe), zinc (Zn), copper (Cu), manganese (Mn) and selenium (Se) in serum of 41 children with newly diagnosed IBD (27 CD and 14 UC) and 20 healthy controls were determined by inductively coupled plasma mass spectrometry (ICP-MS) and atomic fluorescence spectrometry (AFS) at the moment of diagnosis and after one year of treatment. RESULTS The obtained results revealed significant differences in serum concentration profile of studied ETEs' for IBD pediatric patients and healthy controls. Decrease of iron, zinc and selenium and increase of copper and manganese serum concentration were observed in IBD patients at the time of diagnosis. The changes were reversible and after one year of treatment the studied ETEs serum concentration profile resembled much more that observed for healthy controls. Correlations between studied ETEs levels within cases (IBD, CD, UC) were also found to be different from those in healthy controls (HC). CONCLUSION Although much more studies are required on the subject our results demonstrate a clinical value of ETEs serum concentration profile in pediatric IBD patients regarding disease development.

Abstract
Nutritional deficiencies and malnutrition are considered to be related to ulcerative colitis (UC); however, the association between serum levels of micronutrients and UC is not well known. This study aimed to evaluate the serum levels of micronutrients in UC patients and investigate their association with disease activity.This cross-sectional study was conducted on UC patients visiting the Department of Gastroenterology at 3 different teaching hospitals between January 2016 and January 2017. UC activity was measured based on Truelove and Witts' severity index and guidelines for colonoscopy. A healthy gender- and age-matched group was also selected. Serum levels of zinc, copper, selenium, ceruloplasmin, albumin, and total protein were compared between the 2 groups of UC patients and healthy subjects using independent-samples t test. Also, the association between serum levels of micronutrients and UC activity was assessed by using Pearson and Spearman correlation coefficient tests. The data were analyzed by SPSS version 21, considering P ≤.05 as the statistical significance level.Overall, 112 (54 male and 58 female) individuals with the mean age of 34.6 years were studied in the 2 groups of UC patients (n = 56) and healthy subjects (n = 56). The 2 groups were homogeneous in terms of age, gender, marital status, place of residence, and educational level (P >.05). The serum levels of total protein (6.41 ± 1.1 vs 7.41 ± 0.4 g/dL; P = .0001), albumin (4.72 ± 1.1 vs 5.19 ± 0.28 g/dL; P = .0001), zinc (679 ± 62 vs 1055 ± 156 μg/L; P = .0001), and selenium (81.85 ± 6.4 vs 108.4 ± 12.98 micg/L; P = .0001) were significantly lower in the UC patients. The serum level of copper did not differ significantly between the 2 groups (P = .1).Considering the simultaneous reduction in nutritional criteria in the UC patient group, malnutrition appears to be a factor affecting micronutrient deficiency in patients with UC.

Abstract
Patients with inflammatory bowel disease (IBD) are at high risk for nutritional deficiencies because of long-term inflammation in the gut mucosa and decreased oral intake. Because inflammation responses affect serum micronutrient concentrations, serum levels are limited in reflecting body nutrient status in acute and chronic illness. We investigated the usefulness of measuring trace elements in hair as reliable markers of nutritional status compared to serum levels in children with IBD. We retrospectively analyzed pediatric patients newly diagnosed with Crohn's disease (n = 49) and ulcerative colitis (n = 16) and controls (n = 29) from 2012 to 2016. Serum micronutrient levels, inflammatory markers, and hair trace element content were evaluated and compared at the time of diagnosis and before initiating treatment. Serum calcium (p < 0.001), iron (p < 0.001), zinc (p = 0.013), selenium (p = 0.008), albumin (p < 0.001), prealbumin (p < 0.001), hemoglobin and hematocrit (p < 0.001), and WBC (p = 0.001) and lymphocytes (p < 0.001) differed significantly between the groups. After adjustment for the erythrocyte sedimentation rate, serum zinc and selenium levels were no longer significantly different between the groups (p < 0.062 and p < 0.057, respectively). Following hair analysis for mineral and trace elements, iron (p = 0.033), selenium (p = 0.017), and manganese (p = 0.009) differed significantly between the groups. Serum micronutrient levels need cautious interpretation in conjunction with inflammatory markers. Hair mineral and trace element measurement may support understanding micronutrient status in children with IBD.

Abstract
UC a form of IBD is a chronic inflammatory disorder of large intestine, with unknown etiology. Reports suggest a critical role of COX-2 dependent prostaglandins (PGs) mediated inflammatory pathway in pathophysiology of UC. However, COX inhibition using NSAIDs exacerbate IBD and thus is not a viable solution. Currently, in DSS induced experimental colitis in mice, we have demonstrated that dietary Se supplementation (0.5ppm as sodium selenite) symptomatically resolves the signs of inflammation in a redox sensitive manner as compared to Se deficient (0.01ppm) conditions, as seen by modulation in oxidative stress markers, morphological changes, histopathological examinations, biochemical studies such as MPO activity, activity of intestinal markers enzymes as well as mRNA and expressions of various pro and anti-inflammatory factors such as, mPGES, hPGDS, TXAS, 15-PGDH, GPX-1 and GPX-2. These findings were validated and correlated with changes in the biophysical parameters such as membrane fluidity, electrical parameters (impedance), transport across the colonic tissue and FTIR. Current study not only concluded that Se at supranutritional concentrations by modulating the redox status relieves the signs of colitis by regulating COX dependent PG biosynthetic pathway, but also sheds light on the biophysical characterization of these inflammatory/resolution pathways involved in UC.

Abstract
BACKGROUND AND AIMS A growing body of evidence supports the need for detailed attention to nutrition and diet in children with inflammatory bowel disease (IBD). We aimed to define the steps in instituting dietary or nutritional management in light of the current evidence and to offer a useful and practical guide to physicians and dieticians involved in the care of pediatric IBD patients. METHODS A group of 20 experts in pediatric IBD participated in an iterative consensus process including 2 face-to-face meetings, following an open call to Nutrition Committee of the European Society of Pediatric Gastroenterology, Hepatology and Nutrition Porto, IBD Interest, and Nutrition Committee. A list of 41 predefined questions was addressed by working subgroups based on a systematic review of the literature. RESULTS A total of 53 formal recommendations and 47 practice points were endorsed with a consensus rate of at least 80% on the following topics: nutritional assessment; macronutrients needs; trace elements, minerals, and vitamins; nutrition as a primary therapy of pediatric IBD; probiotics and prebiotics; specific dietary restrictions; and dietary compounds and the risk of IBD. CONCLUSIONS This position paper represents a useful guide to help the clinicians in the management of nutrition issues in children with IBD.

Abstract
The incidence of inflammatory bowel disease (IBD) and associated oxidative stress is increasing. The antioxidant mineral selenium (Se) was measured in serum samples from 106 IBD patients (53 with ulcerative colitis (UC) and 53 with Crohn’s disease (CD)) and from 30 healthy controls. Serum Se concentrations were significantly lower in UC and CD patients than in healthy controls (p < 0.001) and significantly lower in CD patients than in UC patients (p = 0.006). Se concentrations in patients were significantly influenced by sex, body mass index (BMI), the inflammatory biomarker α-1-antitrypsin, surgery, medical treatment, the severity, extent, and form of the disease and the length of time since onset (p < 0.05). Se concentrations in IBD patients were positively and linearly correlated with nutritional (protein, albumin, prealbumin, cholinesterase and total cholesterol) and iron status-related (hemoglobin, Fe and hematocrit) parameters (p < 0.05). A greater impairment of serum Se and cardiovascular status was observed in CD than in UC patients. An adequate nutritional Se status is important in IBD patients to minimize the cardiovascular risk associated with increased inflammation biomarkers, especially in undernourished CD patients, and is also related to an improved nutritional and body iron status.

Abstract
Selenium is an essential micronutrient that is incorporated into at least 25 selenoproteins encoded by the human genome, many of which serve antioxidant functions. Because patients with inflammatory bowel disease (IBD) demonstrate nutritional deficiencies and are at increased risk for colon cancer due to heightened inflammation and oxidative stress, selenoprotein dysfunction may contribute to disease progression. Over the years, numerous studies have analyzed the effects of selenoprotein loss and shown that they are important mediators of intestinal inflammation and carcinogenesis. In particular, recent work has focused on the role of selenoprotein P (SEPP1), a major selenium transport protein which also has endogenous antioxidant function. These experiments determined SEPP1 loss altered immune and epithelial cellular function in a murine model of colitis-associated carcinoma. Here, we discuss the current knowledge of SEPP1 and selenoprotein function in the setting of IBD, colitis, and inflammatory tumorigenesis.

Abstract
Nutrigenomics is an emerging science which investigates a certain area of nutrition that uses molecular tools to search access and understand the several responses obtained through a certain diet applied between individual and population groups. The increased need for the use of personalised nutrition in patients is increasing and research is being made on its possible effects. However, research on nutrigenomics and in particular, obesity is still ongoing. Following a current metanalysis on thirty-eight nutrigenomics genes, it seems that a definite association between the genes usually examined in nutrigenomics testing and several diet-related diseases is lacking, even though there is a limited number of studies associating them. In 2014, literature search results in a great number of studies on several polymorphisms. This heterogeneity could only show the way towards new research aims. Nutrigenomics was born due to the need to move from Epidemiology and Physiology to Molecular Biology and Genetics. Currently, there are steps that need to be considered in order for nutrigenomics to be applied: the genes, the gene/protein network, and the strategy towards the determination of the nutrients' influence on gene/protein expression. It is certainly an interesting evolving science with many areas to be investigated further and from different perspectives, as it involves ethics, medicine, genetics and nutrition.

Abstract
Inflammation is a hallmark of inflammatory bowel disease (IBD) that involves macrophages. Given the inverse link between selenium (Se) status and IBD-induced inflammation, our objective was to demonstrate that selenoproteins in macrophages were essential to suppress proinflammatory mediators, in part, by the modulation of arachidonic acid metabolism. Acute colitis was induced using 4% dextran sodium sulfate in wild-type mice maintained on Se-deficient (<0.01 ppm Se), Se-adequate (0.08 ppm; sodium selenite), and two supraphysiological levels in the form of Se-supplemented (0.4 ppm; sodium selenite) and high Se (1.0 ppm; sodium selenite) diets. Selenocysteinyl transfer RNA knockout mice (Trsp(fl/fl)LysM(Cre)) were used to examine the role of selenoproteins in macrophages on disease progression and severity using histopathological evaluation, expression of proinflammatory and anti-inflammatory genes, and modulation of PG metabolites in urine and plasma. Whereas Se-deficient and Se-adequate mice showed increased colitis and exhibited poor survival, Se supplementation at 0.4 and 1.0 ppm increased survival of mice and decreased colitis-associated inflammation with an upregulation of expression of proinflammatory and anti-inflammatory genes. Metabolomic profiling of urine suggested increased oxidation of PGE2 at supraphysiological levels of Se that also correlated well with Se-dependent upregulation of 15-hydroxy-PG dehydrogenase (15-PGDH) in macrophages. Pharmacological inhibition of 15-PGDH, lack of selenoprotein expression in macrophages, and depletion of infiltrating macrophages indicated that macrophage-specific selenoproteins and upregulation of 15-PGDH expression were key for Se-dependent anti-inflammatory and proresolving effects. Selenoproteins in macrophages protect mice from dextran sodium sulfate-colitis by enhancing 15-PGDH-dependent oxidation of PGE2 to alleviate inflammation, suggesting a therapeutic role for Se in IBD.

Abstract
Inadequate dietary intake of the essential trace element selenium (Se) is thought to be a risk factor for several chronic diseases associated with oxidative stress and inflammation. Biological actions of Se occur through low-molecular weight metabolites and through selenoproteins. Several key selenoproteins including glutathione peroxidases; selenoproteins M, P, and S; and selenium-binding protein 1 have been detected in the intestine. Interestingly, Se and antioxidant selenoproteins are known to modulate differentiation and function of immune cells and contribute to avoid excessive immune responses. This review discusses the role of Se and intestinal selenoproteins in inflammatory bowel diseases, based on data from human, animal, and in vitro studies. In humans, Se deficiency is commonly observed in patients with Crohn's disease. In animal models of experimental colitis, the Se status was negatively correlated with the severity of the disease. While the cause-effect relationship of these observations remains to be clarified, the beneficial outcome of dietary Se supplementation and an optimization of selenoprotein biosynthesis in murine inflammatory bowel disease models have led to investigations of targets and actions of Se in the gastrointestinal tract. The Se status affects gene expression, signaling pathways, and cellular functions in the small and large intestine as well as the gut microbiome composition. This data, particularly from animal experiments, hold promise that adequate dietary Se supply may counteract chronic intestinal inflammation in humans.

Abstract
The epithelium of the gastrointestinal tract is one of the most versatile tissues in the organism, responsible for providing a tight barrier between dietary and bacterial antigens and the mucosal and systemic immune system while maintaining efficient digestive and absorptive processes to ensure adequate nutrient and energy supply. Inflammatory bowel diseases (Crohn's disease and ulcerative colitis) are associated with a breakdown of both functions, which in some cases are clearly interrelated. In this updated literature review, we focus on the effects of intestinal inflammation and the associated immune mediators on selected aspects of the transepithelial transport of macronutrients and micronutrients. The mechanisms responsible for nutritional deficiencies are not always clear and could be related to decreased intake, malabsorption, and excess losses. We summarize the known causes of nutrient deficiencies and the mechanism of inflammatory bowel disease-associated diarrhea. We also overview the consequences of impaired epithelial transport, which infrequently transcend its primary purpose to affect the gut microbial ecology and epithelial integrity. Although some of those regulatory mechanisms are relatively well established, more work needs to be done to determine how inflammatory cytokines can alter the transport process of nutrients across the gastrointestinal and renal epithelia.

Abstract
Inflammatory bowel disease includes ulcerative colitis and Crohn's disease, which are both inflammatory disorders of the gastrointestinal tract. Both types of inflammatory bowel disease have a complex etiology, resulting from a genetically determined susceptibility interacting with environmental factors, including the diet and gut microbiota. Genome Wide Association Studies have implicated more than 160 single-nucleotide polymorphisms in disease susceptibility. Consideration of the different pathways suggested to be involved implies that specific dietary interventions are likely to be appropriate, dependent upon the nature of the genes involved. Epigenetics and the gut microbiota are also responsive to dietary interventions. Nutrigenetics may lead to personalized nutrition for disease prevention and treatment, while nutrigenomics may help to understand the nature of the disease and individual response to nutrients.

Abstract
Selenium (Se) is an essential micronutrient that exerts its functions via selenoproteins. Little is known about the role of Se in inflammatory bowel disease (IBD). Epidemiological studies have inversely correlated nutritional Se status with IBD severity and colon cancer risk. Moreover, molecular studies have revealed that Se deficiency activates WNT signaling, a pathway essential to intestinal stem cell programs and pivotal to injury recovery processes in IBD that is also activated in inflammatory neoplastic transformation. In order to better understand the role of Se in epithelial injury and tumorigenesis resulting from inflammatory stimuli, we examined colonic phenotypes in Se-deficient or -sufficient mice in response to dextran sodium sulfate (DSS)-induced colitis, and azoxymethane (AOM) followed by cyclical administration of DSS, respectively. In response to DSS alone, Se-deficient mice demonstrated increased morbidity, weight loss, stool scores, and colonic injury with a concomitant increase in DNA damage and increases in inflammation-related cytokines. As there was an increase in DNA damage as well as expression of several EGF and TGF-β pathway genes in response to inflammatory injury, we sought to determine if tumorigenesis was altered in the setting of inflammatory carcinogenesis. Se-deficient mice subjected to AOM/DSS treatment to model colitis-associated cancer (CAC) had increased tumor number, though not size, as well as increased incidence of high grade dysplasia. This increase in tumor initiation was likely due to a general increase in colonic DNA damage, as increased 8-OHdG staining was seen in Se-deficient tumors and adjacent, non-tumor mucosa. Taken together, our results indicate that Se deficiency worsens experimental colitis and promotes tumor development and progression in inflammatory carcinogenesis.

Abstract
Ileal pouch-anal anastomosis (IPAA) is a classical surgery for ulcerative colitis patients. However, knowledge on trace element alteration in patients who had undergone this surgery is limited. This study was conducted to assess trace element alteration in patients with ulcerative colitis before and after ileal pouch-anal anastomosis. Preoperative (40) and postoperative (35) ulcerative colitis patients were studied. The dietary assessment of trace element intake was undertaken by a semiquantitative food frequency questionnaire. Patients' trace element status of zinc, copper, manganese, selenium, calcium, iron, and vitamin D3 was assessed by measuring their blood concentrations. We found that with the similar dietary intake, there was no statistical difference in the concentrations of plasma copper, iron, calcium, and vitamin D3 in the two groups (P > 0.05). Compared with preoperative patients, postoperative patients had higher concentrations of plasma zinc (14.51 ± 4.75 μmol/l) and manganese (0.21 ± 0.11 μmol/l) and lower concentrations of plasma selenium (0.86 ± 0.58 μmol/l). Both preoperative and postoperative mean concentrations of plasma calcium and vitamin D3 were below their reference range, respectively. We conclude that IPAA does not seem to alter patients' abnormal trace elements completely. It is important to monitor and supply some specified trace elements even in postoperative patients.

Abstract
Inflammatory bowel disease (IBD) has classically been associated with malnutrition and weight loss, although this has become less common with advances in treatment and greater proportions of patients attaining clinical remission. However, micronutrient deficiencies are still relatively common, particularly in CD patients with active small bowel disease and/or multiple resections. This is an updated literature review of the prevalence of major micronutrient deficiencies in IBD patients, focusing on those associated with important extraintestinal complications, including anemia (iron, folate, vitamin B12) bone disease (calcium, vitamin D, and possibly vitamin K), hypercoagulability (folate, vitamins B6, and B12), wound healing (zinc, vitamins A and C), and colorectal cancer risk (folate and possibly vitamin D and calcium).

Abstract
New Zealand has one of the highest incidence rates of Crohn’s Disease (CD), whilst the serum selenium status of New Zealanders is amongst the lowest in the world. A prospective case-control study in Auckland, New Zealand considered serum selenium as a potential CD risk factor. Serum selenium levels were significantly lower in CD patients compared to controls (101.8 ± 1.02 vs. 111.1 ± 1.01 ng/mL) (p = 5.91 × 10−8). Recent detailed studies in the United Kingdom have suggested an optimal serum level around 122 ng/mL, making the average CD patient in New Zealand selenium deficient. Of the 29 single nucleotide polymorphisms (SNPs) tested, 13 were found to significantly interact with serum selenium on CD. After adjustment for multiple testing, a significant interaction with serum selenium on CD was found for three SNPs, namely rs17529609 and rs7901303 in the gene SEPHS1, and rs1553153 in the gene SEPSECS. These three SNPs have not been reported elsewhere as being significantly associated with selenium or CD. It is unclear as to whether lower selenium levels are a cause or an effect of the disease.

Abstract
Dietary selenium (]Se), mainly through its incorporation into selenoproteins, plays an important role in inflammation and immunity. Adequate levels of Se are important for initiating immunity, but they are also involved in regulating excessive immune responses and chronic inflammation. Evidence has emerged regarding roles for individual selenoproteins in regulating inflammation and immunity, and this has provided important insight into mechanisms by which Se influences these processes. Se deficiency has long been recognized to negatively impact immune cells during activation, differentiation, and proliferation. This is related to increased oxidative stress, but additional functions such as protein folding and calcium flux may also be impaired in immune cells under Se deficient conditions. Supplementing diets with above-adequate levels of Se can also impinge on immune cell function, with some types of inflammation and immunity particularly affected and sexually dimorphic effects of Se levels in some cases. In this comprehensive article, the roles of Se and individual selenoproteins in regulating immune cell signaling and function are discussed. Particular emphasis is given to how Se and selenoproteins are linked to redox signaling, oxidative burst, calcium flux, and the subsequent effector functions of immune cells. Data obtained from cell culture and animal models are reviewed and compared with those involving human physiology and pathophysiology, including the effects of Se levels on inflammatory or immune-related diseases including anti-viral immunity, autoimmunity, sepsis, allergic asthma, and chronic inflammatory disorders. Finally, the benefits and potential adverse effects of intervention with Se supplementation for various inflammatory or immune disorders are discussed.

Abstract
Preeclampsia is a complex multisystem disorder of pregnancy where oxidative stress plays an important aetiological role. The role of selenium in the synthesis of endogenous antioxidants is well documented, and a significant reduction in selenium has been reported in preeclamptic women. The objective of this study was to map global selenium status and preeclampsia incidence. This study identified peer reviewed journal articles reporting national preeclampsia incidence (%) and matched these with reported values of selenium intake and plasma/serum selenium concentrations (μg/L). Matched data were obtained for 45 regions, reporting 6456,570 births, spanning Europe, Asia, Australasia, Africa, North and South America. Increasing plasma selenium concentration was found to be correlated with a reduction in preeclampsia incidence (Pearson's r=-0.604, P<0.0001). Countries with a reported serum/plasma selenium level of ⩾95μg/L were considered selenium sufficient and a significant reduction in preeclampsia incidence for countries above this value (P=0.0007) was noted. Significant reductions in preeclampsia incidence were found to coincide with increases in plasma/serum selenium concentration in the New Zealand (P=0.0003) and Finland (0.0028) populations following Government intervention. This study supports the hypothesis that selenium supplementation may be beneficial in reducing oxidative stress in women at risk of preeclampsia.

Abstract
BACKGROUND L-arginine (L-Arg) is a semi-essential amino acid that is the substrate for both nitric oxide and polyamine synthesis. Cellular uptake of L-Arg is an active transport process that is subject to competitive inhibition by L-ornithine (L-Orn) and L-lysine (L-Lys). We investigated L-Arg utilization in patients with ulcerative colitis (UC). METHODS Serum was collected from 14 normal controls and 22 UC patients with pancolitis of moderate or severe activity by histopathology score. The Mayo Disease Activity Index (DAI) and endoscopy subscore were assessed. Serum amino acid levels were measured by high-performance liquid chromatography. Arginine availability index (AAI) was defined as [L-Arg]/([L-Orn] + [L-Lys]). RESULTS Serum L-Arg levels were significantly associated with histopathologic grade (P = 0.001). L-Arg levels were increased in subjects with severe colitis when compared to those with moderate colitis or normal mucosa. L-Orn + L-Lys levels were also increased in severe colitis, so that AAI was not significantly increased. L-Arg levels were also strongly associated with the endoscopy subscore (P < 0.001). There was a strong correlation between DAI and L-Arg levels (r = 0.656, P < 0.001). CONCLUSIONS Serum L-Arg levels correlate with UC disease severity but availability is not increased due to competitive inhibition by L-Orn and L-Lys. Our findings suggest that L-Arg uptake by cells in the inflamed colon is defective, which may contribute to the pathogenesis of UC. Studies delineating the mechanism of uptake inhibition could enhance our understanding of UC or lead to novel treatment options.

Abstract
Undernutrition as well as specific nutrient deficiencies has been described in patients with Crohn's disease (CD), ulcerative colitis (UC) and short bowel syndrome. In the latter, water and electrolytes disturbances may be a major problem. The present guidelines provide evidence-based recommendations for the indications, application and type of parenteral formula to be used in acute and chronic phases of illness. Parenteral nutrition is not recommended as a primary treatment in CD and UC. The use of parenteral nutrition is however reliable when oral/enteral feeding is not possible. There is a lack of data supporting specific nutrients in these conditions. Parenteral nutrition is mandatory in case of intestinal failure, at least in the acute period. In patients with short bowel, specific attention should be paid to water and electrolyte supplementation. Currently, the use of growth hormone, glutamine and GLP-2 cannot be recommended in patients with short bowel.

Abstract
The aim of the study is to evaluate the serum copper, ceruloplasmin and 24-h urine copper levels in celiac patients. Serum copper, ceruloplasmin and 24-h urine measurements were evaluated in patients with celiac (n = 32), Crohn's (n = 25), Wilson's (n = 11) and in a healthy group (n = 35). Serum and 24-h urine zinc levels, AST, ALT, BUN, creatinine, iron, hemoglobin, hematocrit, lymphocyte, sedimentation and CRP levels were also measured. Results were evaluated statistically and significance was accepted as meaningful if P < 0.05. In celiacs, levels of urine copper were high (52 +/- 29 microg/day, P < 0.000) but serum copper was the same as in controls (105 +/- 16 microg/dl, P < 0.158). High urinary copper of celiacs were coming out in women (56 +/- 30 microg/day) and in man (33 +/- 17 microg/day, P < 0.115). Most celiacs were female (P < 0.001). Serum copper and ceruloplasmin levels in all groups were higher in women than in men and this was meaningful for serum copper in the control group (P < 0.045) and for ceruloplasmin in Crohn's (P < 0.055) and control groups (P < 0.031). Serum (70 +/- 14 microg/dl, P < 0.000) and urine zinc levels (25 +/- 15 microg/dl, P < 0.039) of celiacs were low. Ceruloplasmin levels were higher in celiacs (337 +/- 64 U/1) and Crohn's patients (366 +/- 47 U/l, P < 0.000). Correlations observed in the groups of celiac (P < 0.029) and Crohn's (P < 0.024), celiac and Wilson's (P < 0.001) and Crohn's and Wilson's (P < 0.001) between the ceruloplasmin and 24-h urine copper parameters. AST and ALT levels were higher in celiac and Wilson's patients than in Crohn's patients and controls. Mean CRP levels were significantly higher in Crohn's than others. Lymphocyte counts were meaningfully higher in celiacs. Statistically, while mean iron, hemoglobulin and hematocrit levels of celiac and Crohn groups were meaningfully lower than the normal and Wilson's group, it was similar in Wilson's and the control group. Serum copper (85 +/- 26 microg/dl, P < 0.158) and ceruloplasmin (219 +/- 83 U/l, P < 0.001) levels were low and 24-h urine copper levels were high (415 +/- 346 microg/day) in Wilson's group. Increased urinary loss may be another cause of copper deficiency in female celiacs besides malabsorption and this topic needs more investigation. Increased urinary copper levels in celiac women should not always be regarded as a diagnosis of Wilson's disease.

Altered status of antioxidant vitamins and fatty acids in patients with inactive inflammatory bowel disease. Clin Nutr 2008; 27:571-8. [PMID: 18316141 DOI: 10.1016/j.clnu.2008.01.007] [Citation(s) in RCA: 65] [Impact Index Per Article: 4.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/10/2007] [Revised: 11/01/2007] [Accepted: 01/11/2008] [Indexed: 02/07/2023]
Abstract
BACKGROUND & AIMS Data regarding the nutritional status, antioxidant compounds and plasma fatty acid (FA) composition in inactive IBD are conflicting. We compared plasma levels of antioxidants and FA of patients with inactive IBD with active IBD and controls. METHODS Plasma levels of vitamin C, vitamin E, carotenoids, saturated, monounsaturated and polyunsaturated FA, inflammatory markers and nutritional status were determined after an overnight fast in 132 patients with quiescent IBD (40.6+/-13.2 years, 87F/45M), 35 patients with active disease (37.9+/-12.1 years, 25F/10M) and 45 age- and BMI-matched healthy controls (38.1+/-10.5 years, 39F/6M). Results are expressed as mean+/-SD or median [25th percentile;75th percentile]. RESULTS Body mass index (BMI) was normal in inactive (23.9+/-4.7 kg/m(2)), active IBD (22.7+/-4.2 kg/m(2)) and controls (22.3+/-1.9 kg/m(2)). Compared with controls patients with quiescent IBD showed significantly decreased plasma levels of carotenoids (1.85 [1.37;2.56] vs 1.39 [0.88;1.87] micromol/L) and vitamin C (62.3 [48.7;75.0] vs 51.0 [36.4;77.6] micromol/L), increased levels of saturated FA (3879 [3380;4420] vs 3410 [3142;3989] micromol/L) and monounsaturated FA (2578 [2258;3089] vs 2044 [1836;2434] micromol/L) and similar levels of vitamin E and polyunsaturated FA. Results in active disease were similar to inactive disease. CONCLUSION This study shows that antioxidant status and FA profile in a larger population of IBD patients are disturbed independently from disease activity and despite normal overall nutritional status.
