Ashrafizadeh M, Aref AR, Sethi G, Ertas YN, Wang L. Natural product/diet-based regulation of macrophage polarization: Implications in treatment of inflammatory-related diseases and cancer. J Nutr Biochem 2024; 130:109647. [PMID: 38604457 DOI: 10.1016/j.jnutbio.2024.109647] [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: 10/09/2023] [Revised: 03/28/2024] [Accepted: 04/08/2024] [Indexed: 04/13/2024]
Abstract
Macrophages are phagocytic cells with important physiological functions, including the digestion of cellular debris, foreign substances, and microbes, as well as tissue development and homeostasis. The tumor microenvironment (TME) shapes the aggressiveness of cancer, and the biological and cellular interactions in this complicated space can determine carcinogenesis. TME can determine the progression, biological behavior, and therapy resistance of human cancers. The macrophages are among the most abundant cells in the TME, and their functions and secretions can determine tumor progression. The education of macrophages to M2 polarization can accelerate cancer progression, and therefore, the re-education and reprogramming of these cells is promising. Moreover, macrophages can cause inflammation in aggravating pathological events, including cardiovascular diseases, diabetes, and neurological disorders. The natural products are pleiotropic and broad-spectrum functional compounds that have been deployed as ideal alternatives to conventional drugs in the treatment of cancer. The biological and cellular interactions in the TME can be regulated by natural products, and for this purpose, they enhance the M1 polarization of macrophages, and in addition to inhibiting proliferation and invasion, they impair the chemoresistance. Moreover, since macrophages and changes in the molecular pathways in these cells can cause inflammation, the natural products impair the pro-inflammatory function of macrophages to prevent the pathogenesis and progression of diseases. Even a reduction in macrophage-mediated inflammation can prevent organ fibrosis. Therefore, natural product-mediated macrophage targeting can alleviate both cancerous and non-cancerous diseases.

[PMID: 38830628 DOI: 10.1093/ibd/izae120] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/21/2024] [Indexed: 06/05/2024]
Abstract
BACKGROUND Increased mortality rates have been found in patients suffering from inflammatory bowel disease (IBD). The Faroe Islands have the highest occurrence of IBD, mainly ulcerative colitis (UC). This study investigated mortality of patients with IBD compared with the general Faroese population. METHODS All patients diagnosed with IBD from 1966-2020 were included, as well as population mortality data. All-cause and cause-specific mortality in the IBD cohort was compared with the population by standardized incidence ratios (SIRs). Risk factors for death within the cohort were assessed by hazard ratios (HRs) using Cox regression. RESULTS Overall mortality was not increased in patients with Crohn's disease (CD; SIR 0.9; 95% confidence interval [CI], 0.56-1.35) or UC (SIR 1.0; 95% CI, 0.83-1.25). However, patients with UC had an elevated risk of dying from digestive diseases (SIR 4.3; 95% CI, 2.16-7.74). Patients with IBD had lower risk of death of cardiovascular diseases compared with the background population (SIR 0.7; 95% CI, 0.50-0.93). Risk factors for mortality included male gender, age at diagnosis, and use of steroids. Protective factors were use of 5-aminosalicylic acid (5-ASA), thiopurines, and biological treatment. CONCLUSIONS No increased risk of all-cause mortality in patients with CD or UC was found in this nationwide study compared with the entire Faroese population over more than 5 decades. The risk of death due to digestive diseases was, however, increased in patients with UC, while mortality risk of cardiovascular diseases was lower in patients with IBD.

Risk of malignancy in a high-incidence population-based cohort of Faroese patients with inflammatory bowel disease from 1960 to 2020 - a Faroese IBD cohort study. Scand J Gastroenterol 2024; 59:661-668.

Abstract
BACKGROUND The association between inflammatory bowel disease (IBD) and malignancy remains disputed despite many observational studies. The Faroese population exhibits the highest occurrence of IBD in the world. This study aimed to investigate the cancer risk in Faroese IBD patients in a nationwide IBD cohort. METHODS This study included all IBD patients diagnosed in the Faroe Islands between 1960 and 2020. Clinical demographics and cancer diagnoses were retrieved from patient files and the Faroese cancer registry. Cancer risk in IBD patients was calculated as standardized incidence ratios (SIRs) based on the Faroese background population's age- and sex-specific cancer incidence rates, retrievable from NORDCAN. RESULTS The cohort consisted of 699 patients with a total follow-up time of 9,629 person-years. Overall, the risk of cancer was not statistically significantly increased compared to the background population. Patients diagnosed with cancer at age 50-59 years had higher overall cancer risk (SIR 1.8; 95% CI, 1.02-2.99) as did UC patients diagnosed with IBD at 50-59 (SIR 2.1; 95% CI, 1.10-3.54). Absolute numbers were small and no estimates for site-specific cancers reached statistical significance, though lung, breast, and cancer of the female reproductive organs were elevated among IBD and UC patients, and colorectal cancer in CD patients. CONCLUSIONS This nationwide study found no statistically significantly increased risk of cancer among Faroese patients with CD or UC, except from age 50 to 59 years. While the incidence of IBD is significantly higher in the Faroe Islands than in other countries, risk estimates of cancers are comparable.

Abstract
BACKGROUND The real-world application of STRIDE-II treatment targets to identify whether disease control is optimal in Crohn's disease (CD) and ulcerative colitis (UC) is not well known. AIMS This study aimed to estimate proportions of patients with suboptimally controlled CD and UC in real-world Canadian healthcare settings and the impact on quality of life (QoL). METHODS The noninterventional, multicenter, observational IBD-PODCAST Canada study comprised a single study visit involving routine assessments, patient- and clinician-completed questionnaires, and a retrospective chart review. Primary outcomes were proportions of patients with STRIDE-II-based red flags indicative of suboptimal disease control and mean ± standard deviation Short Inflammatory Bowel Disease Questionnaire (SIBDQ) scores. Secondary outcomes included proportions of patients and clinicians subjectively reporting suboptimal control. RESULTS Among 163 enrolled patients from 10 sites, 45/87 patients with CD (51.7%; 95% CI: 40.8%, 62.6%) and 33/76 patients with UC (43.3%; 95% CI: 32.1%, 55.3%) had suboptimal disease control based on STRIDE-II criteria. Suboptimal control was subjectively reported at lower proportions (patients: CD, 15.0%; UC, 18.6%; clinicians: CD, 19.5%; UC, 25.0%). Numerically lower SIBDQ scores were observed with suboptimal control (CD, 43.0 ± 10.8; UC, 42.5 ± 12.0) than with optimal control (CD, 58.2 ± 7.2; UC, 57.8 ± 6.6). CONCLUSIONS Approximately 50% (CD) and 40% (UC) of patients from real-world Canadian practices had suboptimal disease control based on STRIDE-II criteria. Suboptimal control was underestimated by patients and clinicians and accompanied by reduced QoL, suggesting further efforts to implement STRIDE-II treat-to-target strategies are needed.

Effect of vinegar steaming on the composition and structure of Schisandra chinensis polysaccharide and its anti-colitis activity. Biomed Chromatogr 2024; 38:e5811. [PMID: 38191780 DOI: 10.1002/bmc.5811] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/21/2023] [Revised: 11/22/2023] [Accepted: 11/28/2023] [Indexed: 01/10/2024]
Abstract
In this study, infrared spectroscopy, high-performance liquid chromatography, and matrix-assisted laser desorption ionization-time-of-flight-mass spectrometry (MALDI-TOF-MS) technology were applied to systematically explain the Schisandra chinensis's polysaccharide transformation in configuration, molecular weight, monosaccharide composition, and anti-ulcerative colitis (UC) activity after vinegar processing. Scanning electron microscopic results showed that the appearance of S. chinensis polysaccharide changed significantly after steaming with vinegar. The MALDI-TOF-MS results showed that the mass spectra of raw S. chinensis polysaccharides (RSCP) were slightly lower than those of vinegar-processed S. chinensis polysaccharides (VSCP). The RSCP showed higher peaks at m/z 1350.790, 2016.796, and 2665.985, all with left-skewed distribution, and the molecular weights were concentrated in the range of 1300-3100, with no higher peak above m/z 5000. The VSCPs showed a whole band below m/z 3000, with m/z 1021.096 being the highest peak, and the intensity decreased with the increase of m/z. In addition, compared to RSCPs, VSCPs can significantly increase the content of intestinal short-chain fatty acids (SCFAs). This study showed that the apparent morphology and molecular weight of S. chinensis's polysaccharides significantly changed after steaming with vinegar. These changes directly affect its anti-UC effect significantly, and its mechanism is closely related to improving the structure and diversity of gut microbiota and SCFA metabolism.

Abstract
BACKGROUND AND AIMS The highest reported incidence rate of inflammatory bowel disease [IBD], and especially of ulcerative colitis [UC], is found in the Faroe Islands. This study aimed to assess the incidence rate and temporal trends in prevalence over six decades. METHODS All incident and prevalent patients diagnosed with IBD between 1960 and 2020 from the nationwide and population-based Faroese IBD cohort were included in this study. All patients fulfilled the Copenhagen Diagnostic Criteria. RESULTS Overall, 873 individuals were diagnosed with IBD during the study period, 559 [64%] with UC, 151 [17%] with Crohn's disease, and 163 [19%] with IBD unclassified. A total of 59 patients had paediatric-onset IBD. The incidence of IBD continued to increase throughout the study period, as the age-standardized incidence rate started at 8 per 100 000 person-years [py] [European Standard Population, ESP] in 1960-79 and reached 70 by 2010-20. In 2021, the age-standardized period prevalence was 1414 per 100 000 persons. The IBD incidence was unevenly distributed among the islands with Sandoy having the highest rate of 106 per 100 000 py in 2010-2020. CONCLUSIONS The incidence of IBD continues to increase in the Faroe Islands, mainly driven by UC. The incidence shows an uneven geographical distribution, which suggests an adverse interaction between unknown environmental factors and genetic traits. The prevalence in 2021 corresponded to 1.3% of the Faroese population. Environmental risk factors are suspected to impact this homogeneous high-risk population; however, the reason for this is unclear.

Abstract
Background and aims: Autoimmune liver diseases are rare diseases, and population-based studies on the epidemiology of autoimmune hepatitis (AIH), primary biliary cholangitis (PBC), and primary sclerosing cholangitis (PSC) are sparse. We aimed to assess the incidence of AIH, PBC, and PSC in the Faroe Islands.Methods: All cases of AIH, PBC, and PSC diagnosed in the Faroe Islands between January 1st, 2004, and December 31st, 2021, were included in this nationwide registry-based cohort study. In addition, we searched all medical records to assess diagnostic criteria and cause of death.Results: The incidences of AIH, PBC, and PSC in the Faroe Islands were 5.2, 2.5 and 0.7 per 100,000 population per year, respectively. Point prevalence per 100,000 population on December 31st 2021, was 71.8 for AIH, 38.5 for PBC, and 11.0 for PSC. Nine AIH patients died after a median of 3 years, three died of hepatocellular carcinoma (HCC), and two died of liver failure. Five PBC patients died after a median of 7 years, one of HCC and one of liver failure. One PSC patient died of cholangiocarcinoma.Conclusion: The incidence and prevalence of AIH, PBC and PSC in the Faroe Islands are among the highest reported in population-based settings.

Abstract
BACKGROUND Therapeutic options for ulcerative colitis (UC) have increased since the introduction of biologics a few decades ago. Due to the wide range of biologics available, physicians have difficulty in selecting biologics and do not know how to balance the best drug between clinical efficacy and safety. This study aimed to compare the efficacy and safety of biologics in treating ulcerative colitis. METHODS In this study, eight electronic databases (PubMed, Web of Science, Cochrane, Embase, Sinomed, China National Knowledge Infrastructure, Chongqing VIP Information, and WanFang Data) were searched to collect eligible studies without language restrictions. Retrieved 1 June 2023, from inception. All articles included in the mesh analysis are randomised controlled trials (RCTs). The inclusion of drugs for each outcome was ranked using a curved surface under cumulative ranking (SUCRA). Higher SUCRA scores were associated with better outcomes, whereas lower SUCRA scores were associated with better safety. This study has registered with PROSPERO, CRD42023389483. RESULTS Induction Therapy: Among the biologic therapies evaluated for induction therapy, vedolizumab demonstrated the highest efficacy in achieving clinical remission (OR vs daclizumab, 9.09; 95% CI, 1.01-81.61; SUCRA 94.1) and clinical response. Guselkumab showed the lowest risk of recurrence of UC (SUCRA 94.9%), adverse events resulting in treatment discontinuation (SUCRA 94.8%), and serious infections (SUCRA 78.0%). Maintenance Therapy: For maintenance therapy, vedolizumab ranked highest in maintaining clinical remission (OR vs mesalazine 4.36; 95% CI, 1.65-11.49; SUCRA 89.7) and endoscopic improvement (SUCRA 92.6). Infliximab demonstrated the highest efficacy in endoscopic improvement (SUCRA 92.6%). Ustekinumab had the lowest risk of infections (SUCRA 92.9%), serious adverse events (SUCRA 91.3%), and serious infections (SUCRA 67.6%). CONCLUSION Our network meta-analysis suggests that vedolizumab is the most effective biologic therapy for inducing and maintaining clinical remission in UC patients. Guselkumab shows promise in reducing the risk of recurrence and adverse events during induction therapy. Infliximab is effective in improving endoscopic outcomes during maintenance therapy. Ustekinumab appears to have a favorable safety profile. These findings provide valuable insights for clinicians in selecting the most appropriate biologic therapy for UC patients.

Possible explanations for the common clinical familial hypercholesterolemia phenotypes in the Faroe Islands. J Clin Lipidol 2023; 17:633-642. [PMID: 37482509 DOI: 10.1016/j.jacl.2023.06.003] [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: 12/08/2022] [Revised: 06/18/2023] [Accepted: 06/19/2023] [Indexed: 07/25/2023]
Abstract
BACKGROUND The prevalence of clinical familial hypercholesterolemia (FH) is very high in the Faroe Islands, but the possible causes are unknown. OBJECTIVES We aimed to describe potential genetic causes of FH in the Faroe Islands and to investigate whether levels of lipoprotein(a) and measures of dietary habits were associated with clinical FH in the Faroe Islands. METHODS In this case-control study, we identified potential clinical FH cases aged 18-75 years registered within a nationwide clinical laboratory database in the Faroe Islands and invited them for diagnostic evaluation according to clinical FH scoring systems. Controls were identified in the background population. Lipoprotein(a) was measured in plasma, while the fatty acid composition was determined in adipose tissue. The habitual diet of the participants was assessed using a food frequency questionnaire. Genetic testing for FH and polygenic variants was performed in a selection of clinical FH cases. RESULTS A total of 121 clinical FH cases and 123 age- and sex-matched controls were recruited. We found a very low frequency of monogenic FH (2.5%), but a high level of polygenic FH (63%) in those genetically tested (67%). High levels of plasma lipoprotein(a) were associated with high odds of clinical FH. Clinical FH cases had a lower intake of saturated fatty acids (SFAs) measured by a high fat-score and a lower content of SFAs in adipose tissue compared with controls. CONCLUSION The high prevalence of FH in the Faroe Islands may be due to polygenic causes of hypercholesterolemia and to a lesser extent other genetic factors and elevated plasma lipoprotein(a) levels.

Abstract
Background Readmission shortly after discharge is indicative of an increased disease severity for patients with ulcerative colitis (UC) and ineffectiveness to medical therapy, which may contribute to a dismal prognosis. Objectives This study aimed to explore prognostic variables with a nomogram to predict unplanned UC-related readmission within 1 year after discharge. Design A retrospective cohort study. Methods Electronic medical records of all UC patients treated at our center between 1 January 2014 and 31 June 2021 were reviewed. A comprehensive analysis of various characteristics, such as demographics, comorbidities, medical history, follow-up appointments, admission endoscopy, histopathologic features, etc., was used to determine the primary end point, which was unplanned UC-related calendar year readmission. Results We found that the unplanned UC-related readmission rate within 1 year was 20.8%. In multivariable cox analysis, the predictors of the Elixhauser comorbidity index [Hazard ratio (HR): 3.50, 95% confidence interval (CI): 1.93-6.37], regular follow-up (HR: 0.29, 95% CI: 0.16-0.53), any history of corticosteroid use (HR: 3.38, 95% CI: 1.83-6.27), seral level of C-reactive protein (HR: 1.01, 95% CI: 1.00-1.02), and the UC endoscopic index of severity (HR: 1.29, 95% CI: 1.05-1.57) independently predicted calendar year readmission after discharge. The established nomogram had a consistently high accuracy in predicting calendar year readmission in the training cohort, with a concordance index of 0.784, 0.825, and 0.837 at 13, 26, and 52 weeks, respectively, which was validated in both the internal and external validation cohorts. Therefore, UC patients were divided into clinically low-, high-, and extremely high-risk groups for readmission, based on the calculated score of 272.5 and 378. Conclusion The established nomogram showed good discrimination and calibration powers in predicting calendar year readmission in high-risk UC patients, who may need intensive treatment and regular outpatient visits.

Abstract
BACKGROUND In microscopic colitis (MC), the incidence has increased over the last decades. The aim of the present study was to determine the incidence of lymphocytic (LC) and collagenous colitis (CC) in the county Skåne (Scania), southern Sweden, during the period 2010-20 with focus both on the temporal and spatial variations. METHODS The MC diagnosis was retrieved from the biopsy registries at the Departments of Pathology. Established diagnostic criteria (increased lymphocyte count, inflammation in lamina propria and in CC a collagen band) were used for diagnosis. Age, gender, date for diagnosis and municipality of residence were retrieved for all patients. RESULTS In total 1985 patients could be identified with a mean age of 62.9 years (SD 15.7) whereof 1415 were women. The incidence for CC was stable with a total age-standardized rate (ASR) per 100 000 person-years of 6.34, (range 4.6-8.1). In LC the ASR was 7.90 (range 1.7-15.2) but increased markedly 2015-20 reaching 15.2 in 2019. Also, the northwest part of the region showed significantly higher ASR:s of LC during the last part of the decade in comparation to the whole region. CONCLUSIONS The incidence of CC was stable during the period while LC differed substantially in a way that indicates that it most probably must be two different disease entities. In LC, in view of the marked and rapid increase, although no definitive explanation could be found, causative environmental factors could be contemplated, why further studies are indicated.

Abstract
BACKGROUND Incidence rates of inflammatory bowel disease [IBD] reported from developed countries are rising, with some levelling out. The aim of this study was to assess the disease burden of IBD by estimating the incidence and prevalence across age groups and projecting these to 2030 in a high-incidence country. METHODS Using an algorithm [incorporating ICD codes, medications and histopathology], patients [n = 69 862] diagnosed with Crohn's disease [CD] or ulcerative colitis [UC] between 1980 and 2017 were identified in the Danish National Patient Registry and included in a nationwide cohort. RESULTS From 1980 to 2017 the overall incidence of CD increased from 5.1 [95% CI: 4.5-5.8] to 15.6 [95% CI: 14.6-16.6] per 100 000, while the incidence of UC increased from 6.2 [95% CI: 5.5-6.9] to 27.2 [95% CI: 25.9-28.6] per 100 000. For paediatric-onset CD [pCD], the incidence increased from 1.9 [95% CI: 1.2-2.8] to 9.9 [95% CI: 8.1-11.8] per 100 000 and from 1.8 [95% CI: 1.2-2.8] to 8.7 [95% CI: 7.1- 10.5] per 100 000 for paediatric-onset UC [pUC]. In 2017, the prevalence of CD and UC was 293 [95% CI: 288-297] and 523 [95% CI: 517-528] per 100 000. For pCD and pUC, the prevalence was 35 [95% CI: 31-38] and 28 [95% CI: 26-32] per 100 000. CONCLUSIONS The incidence of paediatric- and adult-onset IBD in Denmark continues to increase and is among the highest in the world.

Abstract
Here we present results from FarGen Phase I exomes. This dataset is based on the FarGen cohort, which consists of 1,541 individuals from the isolated population of the Faroe Islands. The purpose of this cohort is to serve as a reference catalog of coding variants, and to conduct population genetic studies to better understand the genetic contribution to various diseases in the Faroese population. The first whole-exome data set comprise 465 individuals and a total of 148,267 genetic variants were discovered. Principle Component Analysis indicates that the population is isolated and weakly structured. The distribution of variants in various functional classes was compared with populations in the gnomAD dataset; the results indicated that the proportions were consistent across the cohorts, but probably due to a small sample size, the FarGen dataset contained relatively few rare variants. We identified 19 variants that are classified as pathogenic or likely pathogenic in ClinVar; several of these variants are associated with monogenetic diseases with increased prevalence in the Faroe Islands. The results support previous studies, which indicate that the Faroe Islands is an isolated and weakly structured population. Future studies may elucidate the significance of the 19 pathogenic variants that were identified. The FarGen Phase I dataset is an important step for genetic research in the Faroese population, and the next phase of FarGen will increase the sample size and broaden the scope.

Abstract
Purpose: In this paper, we present age-standardized cancer incidence and mortality rates in the Faroe Islands. We also compare with the Nordic rates and show incidence rate ratios (IRR) and mortality rate ratios (MRR).Materials and methods: The Faroese cancer registry (FCR) was established in 1994, with incidence available from 1960 and mortality from 1983. The FCR is a part of the NORDCAN collaboration, where the different Nordic countries all report anonymized cancer data by standardized methods, ensuring comparability. Validation efforts revealed that 13% of cases had not been reported to the FCR from 2006 to 2019, emphasizing the need for continued validation efforts of cancer registries. After validation, we submitted the updated cancer cases to NORDCAN and now present this data, taken directly from the NORDCAN website (2019 data).Results: We found that the incidence of the summary group all cancers in the Faroe Islands increased from 1960 to 2019, while cancer mortality decreased from 1983 to 2019. Comparisons with Nordic rates showed significantly lower IRRs for cancer in all cancers, bladder and urinary tract, and skin cancer for both sexes, while IRR was lower for breast cancer in women and prostate cancer in men. Contrary, IRR was higher for rectum and kidney cancer in women and esophagus and testicular cancer in men. There was an increased MRR for cancer in female organs, bladder and urinary tract, and kidney cancer in women, and esophagus and pancreas cancer in men. In contrast, malignant hematopoietic diseases and melanoma in women had a lower MRR.Conclusions: Cancer incidence in the Faroe Islands was lower than in the other Nordic countries. Of particular interest, the incidence of testicular cancer saw a steep increase during the last 20 years, and an investigation into possible causes for this is needed.

Abstract
BACKGROUND The Faroe Islands has the world's highest incidence of inflammatory bowel disease (IBD). Epidemiological studies have characterized this unique cohort and a decreased risk of developing IBD with emigration. Therefore, this well-characterized Faroese IBD cohort gives the opportunity to better understand this complex disease. This study represents the first investigation of the gut microbiota for the cohort. METHODS This cross-sectional study consisted of 41 patients with established ulcerative colitis and 144 age- and sex-matched healthy controls recruited through the Faroe Genome project. Participants donated a 1-time fecal sample and completed questionnaires on food frequency, background health, and lifestyle. 16S rRNA amplicon sequencing of the V3-V4 region was performed followed by bioinformatic analysis of taxonomy and diversity metrics. RESULTS The overall bacterial composition in both groups was dominated by Firmicutes and Bacteroidetes. No significant differences were found based on metrics of alpha or beta diversity. However, discriminatory analysis identified differential abundance of several indicator taxa in healthy controls and ulcerative colitis participants, whereas Akkermansia was completely absent from 27% of all study participants. Food frequency questionnaires revealed similar dietary patterns between the 2 groups. CONCLUSION The similarity in bacterial community composition and absence of the beneficial Akkermansia genus in both groups raise further questions concerning the underlying susceptibility toward inflammatory disorders within this high-risk population. Results vary widely by study design and geographic location, which speaks to the need for regionally tuned reference groups and disease-based studies on the Faroe Islands.

Abstract
Background: The demographic history of the Faroe Islands makes this isolated population – founded in the 9th century – interesting for genetic research. The goal of the FarGen project was to recruit individuals to the FarGen infrastructure to promote research into the genetic features of the Faroese people, and to develop a reference panel of population-specific variants. We aimed to recruit 1500 individuals. Participation was voluntary; participants had to donate a blood sample for whole-genome sequencing, and had to answer a questionnaire regarding sociodemographics, health, motivation and attitude towards participation in genetic research. Methods: A total of 1541 participants voluntarily joined the project, donated a blood sample and returned the questionnaire. Results: Answers from the questionnaire show that participants are, in general, European, have children, have a relatively high level of education, rate their health to be good, are willing to participate in future health-related research, and were motivated to sign up primarily to participate in research to help others and local research competency building. Conclusions: Overall, the initial cohort of the FarGen infrastructure comprises 3% of the Faroese population, and represents the general population well based on the collected sociodemographic data. However, there is an excess of women, and some geographic sub-regions and age groups are slightly underrepresented. We find the recruitment method with voluntary sign-up appropriate, and knowledge acquired through the first phase will aid the next phase of the project, with the aim of expanding the FarGen cohort with additional individuals, bio-specimens and body measurements in order to perform multifactorial analyses.

Abstract
INTRODUCTION AND AIMS The primary aim was to explore the epidemiologic trend of pediatric inflammatory bowel disease in Latin America, and the secondary aims were to obtain an overview of the diagnostic/therapeutic focus of the members of the LASPGHAN and examine the relation of case frequency to year, during the study period. MATERIALS AND METHODS Latin American pediatric gastroenterologists participated in an online survey, conducted through the SurveyMonkey platform, that investigated the yearly frequency of new inflammatory bowel disease patients within the time frame of 2005-2016, their disease variety, the gastrointestinal segments affected, and the diagnostic and treatment methods utilized. The correlation of new case frequency with each study year was evaluated. RESULTS A total of 607 patients were studied. The diagnoses were ulcerative colitis in 475 (78.3%) cases, Crohn's disease in 104 (17.1%), and inflammatory bowel disease D unclassified in 28 (4.6%). The trend in ulcerative colitis was a lineal increase in the frequency of new cases related to each study year, with a significant correlation coefficient. Pancolitis was found in 67.6% of the patients. The diagnostic methods included clinical data, endoscopy, and biopsies in more than 99% of the cases, and imaging studies were indicated selectively. Drug regimens were limited to 5-aminosalicylic acid derivatives, azathioprine, 6-mercaptopurine, infliximab, and adalimumab. CONCLUSIONS Pediatric inflammatory bowel disease in Latin America appears to have increased during the years included in the study period, with a predominance of moderate or severe ulcerative colitis. That lineal trend suggests the predictive likelihood of a gradual increase in the coming years, with possible epidemiologic and clinical implications.

Abstract
New data suggest that incidence and prevalence of inflammatory bowel diseases [IBD] are still increasing worldwide, and approximately 0.2% of the European population suffer from IBD at the present time. Medical therapy and disease management have evolved significantly in recent decades, with an emphasis on tight objective monitoring of disease progression and a treat-to-target approach in Europe and also worldwide, aiming to prevent early bowel damage and disability. Surgery rate declined over time in Europe, with 10-30% of CD and 5-10% of UC patients requiring a surgery within 5 years. The health economic burden associated with IBD is high in Europe. Direct health care costs [approximately €3500 in CD and €2000 in UC per patient per year] have shifted from hospitalisation and surgery towards drug-related expenditures with the increasing use of biologic therapy and other novel agents, and substantial indirect costs arise from work productivity loss [approximately €1900 per patient yearly]. The aim of this paper is to provide an updated review of the burden of IBD in Europe by discussing current data on epidemiology, disease course, risk for surgery, hospitalisation, and mortality and cancer risks, as well as the economic aspects, patient disability, and work impairment, by discussing the latest population-based studies from the region.

Abstract
INTRODUCTION The composition of microorganisms is closely related to human health. Antibiotic use during pregnancy may have adverse effects on the neonatal gut microbiome and subsequently affect infant health development, leading to childhood atopy and allergic diseases, intestinal, metabolic and brain disorders, and infection. AREAS COVERED This review includes the effect of maternal antibiotic use during pregnancy on potential diseases in animals and human offspring. EXPERT OPINION Exposure to antibiotics during pregnancy alters offspring outcomes. Alterations in the microbiome may potentially lower the risk of a range of problems and may also be a novel therapeutic target in children later in life.

Abstract
BACKGROUND Inflammatory bowel disease (IBD) is an inflammatory response relative chronic disease in the intestinal tract. Our previous study demonstrated melatonin exerts an improvement effect on stress related IBD. The present study was further performed to clarify the mechanism of melatonin in dextran sodium sulfate (DSS)-induced colitis in mice. METHODS We successfully established a DSS-induced colitis mouse model and hydrogen peroxide (H2O2)-treated intestinal epithelial cells (IECs) with or without melatonin supplementation to explore the improvement of melatonin in the DSS-induced colitis. RESULTS Melatonin supplementation normalized the colitis, oxidative stress, mitochondria dysfunction, apoptosis and inflammation response, including the increase of intestinal permeability, histological score and the level of IL-1β, TNF-α, iNOS, NLRP3, MDA, Bax, Caspase3, Cytochrome C and Caspase9, as well as the reduction of body weight, colon length, Card9, IFN-γ, IL-10, T-AOC, Calpain1, Mfn2, VDAC1, RORα and SIRT1 proteins in DSS-treated mice. However, the improvement effects of melatonin were blocked by MT2 antagonist 4P-PDOT, PI3K antagonist LY294002, AKT antagonist GSK690693 and Nrf2 antagonist ML385, while mimicked by P65 antagonist PDTC in H2O2-IECs. CONCLUSION Melatonin-mediated MT2 activated PI3K/AKT/Nrf2/RORα/SIRT1 pathway and suppressed NF-κB pathway, ultimately improved DSS-induced colitis, which provides evidence for melatonin as an efficient therapy against oxidative stress associated IBD.

Abstract
Objective: The present preliminary cross-sectional study aimed to investigate the extent to which health-related quality of life of patients with inflammatory bowel disease (IBD) was influenced by the outbreak of Covid-19 while controlling for disease activity. Methods: Two samples of 195 (recruited before Covid-19 outbreak) and 707 patients (recruited during the Covid-19-related lockdown) were included. Psychological distress (Hospital Anxiety and Depression Scale, HADS), quality of life (Inflammatory Bowel Disease Questionnaire, IBDQ), and somatization (Patient Health Questionnaire, PHQ-12) were concurrently assessed. Results: Patients with active IBD were more prevalently affected by ulcerative colitis (60.2%, η2 = 0.12) and, expectedly, showed higher psychological distress (HADS, d = 0.34) and somatization (PHQ-12, d = 0.39), as well as poorer disease-specific health-related quality of life (effect sizes for the total and subscale IBDQ scores in the large range of d > 0.50). Hierarchical regression models revealed that setting (pre-Covid-19 outbreak vs. during lockdown) (p < 0.001) explained only a small portion (8%) of the IBDQ variance. IBD-related factors (ulcerative colitis and disease activity) and psychological factors (psychological distress and somatization) added a significant amount of 25 and 27%, respectively, to the explained IBDQ variance. The final model predicted 59% of the explained IBDQ variance. Conclusion: Clinical and psychological manifestations seem to be major impairments in IBD patients both before and during the Covid-19 outbreak. Furthermore, the quality of life of IBD patients seem to be more influenced by psychological and somatizing distressing symptoms than the pandemic-related living conditions.

Abstract
Inflammatory bowel disease (IBD) is a global disease; its evolution can be stratified into four epidemiological stages: Emergence, Acceleration in Incidence, Compounding Prevalence and Prevalence Equilibrium. In 2020, developing countries are in the Emergence stage, newly industrialized countries are in the Acceleration in Incidence stage, and Western regions are in the Compounding Prevalence stage. Western regions will eventually transition to the Prevalence Equilibrium stage, in which the accelerating prevalence levels off as the IBD population ages and possibly as a result of an unexpected rise in mortality during the COVID-19 pandemic. Mitigating the global burden of IBD will require concerted efforts in disease prevention and health-care delivery innovations that respond to changing demographics of the global IBD population. In this Perspective, we summarize the global epidemiology of IBD and use these data to stratify disease evolution into four epidemiological stages.

Abstract
The incidence, prevalence, and cost of care associated with diagnosis and management of inflammatory bowel disease are on the rise. The role of gut microbiota in the causation of Crohn's disease and ulcerative colitis has not been established yet. Nevertheless, several animal models and human studies point towards the association. Targeting intestinal dysbiosis for remission induction, maintenance, and relapse prevention is an attractive treatment approach with minimal adverse effects. However, the data is still conflicting. The purpose of this article is to provide the most comprehensive and updated review on the utility of prebiotics and probiotics in the management of active Crohn's disease and ulcerative colitis/pouchitis and their role in the remission induction, maintenance, and relapse prevention. A thorough literature review was performed on PubMed, Ovid Medline, and EMBASE using the terms "prebiotics AND ulcerative colitis", "probiotics AND ulcerative colitis", "prebiotics AND Crohn's disease", "probiotics AND Crohn's disease", "probiotics AND acute pouchitis", "probiotics AND chronic pouchitis" and "prebiotics AND pouchitis". Observational studies and clinical trials conducted on humans and published in the English language were included. A total of 71 clinical trials evaluating the utility of prebiotics and probiotics in the management of inflammatory bowel disease were reviewed and the findings were summarized. Most of these studies on probiotics evaluated lactobacillus, De Simone Formulation or Escherichia coli Nissle 1917 and there is some evidence supporting these agents for induction and maintenance of remission in ulcerative colitis and prevention of pouchitis relapse with minimal adverse effects. The efficacy of prebiotics such as fructooligosaccharides and Plantago ovata seeds in ulcerative colitis are inconclusive and the data regarding the utility of prebiotics in pouchitis is limited. The results of the clinical trials for remission induction and maintenance in active Crohn's disease or post-operative relapse with probiotics and prebiotics are inadequate and not very convincing. Prebiotics and probiotics are safe, effective and have great therapeutic potential. However, better designed clinical trials in the multicenter setting with a large sample and long duration of intervention are needed to identify the specific strain or combination of probiotics and prebiotics which will be more beneficial and effective in patients with inflammatory bowel disease.

Abstract
Inflammatory bowel disease (IBD), as do most chronic inflammatory disorders, displays unique features and confers different risk factors in male and female patients. Importantly, sex-based differences in IBD exist for epidemiological incidence and prevalence among different age groups, with men and women developing distinct clinical symptoms and disparity in severity of disease. In addition, the presentation of comorbidities in IBD displays strong sex differences. Notably, particular issues exclusive to women's health, including pregnancy and childbirth, require specific considerations in female patients with IBD of childbearing age that can have a substantial influence on clinical outcomes. This Review summarizes the latest findings regarding sex-based differences in the epidemiology, clinical course, comorbidities and response to current therapies in patients with IBD. Importantly, the latest basic science discoveries in this area of investigation are evaluated to provide insight into potential mechanisms underlying the influence of sex on disease pathogenesis, as well as to design more personalized and efficacious care, in patients with IBD.

Abstract
INTRODUCTION AND OBJECTIVES The primary aim was to explore the epidemiologic trend of pediatric inflammatory bowel disease in Latin America, and the secondary aims were to obtain an overview of the diagnostic/therapeutic focus of the members of the LASPGHAN and examine the relation of case frequency to year, during the study period. MATERIALS AND METHODS Latin American pediatric gastroenterologists participated in an online survey, conducted through the SurveyMonkey platform, that investigated the yearly frequency of new inflammatory bowel disease patients within the time frame of 2005 to 2016, their disease variety, the gastrointestinal segments affected, and the diagnostic and treatment methods utilized. The correlation of new case frequency with each study year was evaluated. RESULTS A total of 607 patients were studied. The diagnoses were ulcerative colitis in 475 (78.3%) cases, Crohn's disease in 104 (17.1%), and inflammatory bowel disease D unclassified in 28 (4.6%). The trend in ulcerative colitis was a lineal increase in the frequency of new cases related to each study year, with a significant correlation coefficient. Pancolitis was found in 67.6% of the patients. The diagnostic methods included clinical data, endoscopy, and biopsies in more than 99% of the cases, and imaging studies were indicated selectively. Drug regimens were limited to 5-aminosalicylic acid derivatives, azathioprine, 6-mercaptopurine, infliximab, and adalimumab. CONCLUSIONS Pediatric inflammatory bowel disease in Latin America appears to have increased during the years included in the study period, with a predominance of moderate or severe ulcerative colitis. That lineal trend suggests the predictive likelihood of a gradual increase in the coming years, with possible epidemiologic and clinical implications.

Abstract
Purpose Adolescents and young adults (AYA) with Inflammatory Bowel Disease (IBD) report higher depressive symptoms and anxiety compared to healthy controls, with disease severity and abdominal pain being important factors. In the current study, building on what young people had told us in our previous work, we examined whether embarrassment of the condition, social self-efficacy, and friendship quality mediated the relationship between abdominal pain and disease severity, and mental health/well-being. We also included loneliness as a component of well-being. Methods Data on depression, anxiety, loneliness, friendship quality, social self-efficacy, and disease embarrassment were collected from 130 AYA with IBD ages 14–25 years; data on disease severity and abdominal pain were taken from their medical records. Structural Equation Modeling (SEM) was used to test the relationships between the variables. Results Using SEM, we established that higher IBD disease activity negatively impacted how AYA felt about their friendships and how embarrassed they were about their condition; embarrassment then influenced reports of mental health, including loneliness. Abdominal pain, disease onset, and social self-efficacy directly predicted internalising problems. Conclusion In this sample of 14–25-year-old patients with IBD, specifics about the disease (severity and pain) predicted poorer mental health, suggesting discussion of mental health should be part of the clinical dialogue between patient and consultant. In addition, embarrassment about their condition increased depression, anxiety, and loneliness, mediating the relationship between disease severity and well-being. Thus, it is important to consider how perceived stigma affects those with chronic illness, and those issues should be explored in clinic.

Abstract
BACKGROUND AND AIMS Inflammatory bowel disease [IBD] is often one of the most devastating and debilitating chronic gastrointestinal disorders in children and adolescents. The main objectives here were to systematically review the incidence and prevalence of paediatric IBD across all 51 European states. METHODS We undertook a systematic review and meta-analysis based on PubMed, CINAHL, the Cochrane Library, searches of reference lists, grey literature and websites, covering the period from 1970 to 2018. RESULTS Incidence rates for both paediatric Crohn's disease [CD] and ulcerative colitis [UC] were higher in northern Europe than in other European regions. There have been large increases in the incidence of both paediatric CD and UC over the last 50 years, which appear widespread across Europe. The largest increases for CD have been reported from Sweden, Wales, England, the Czech Republic, Denmark and Hungary, and for UC from the Czech Republic, Ireland, Sweden and Hungary. Incidence rates for paediatric CD have increased up to 9 or 10 per 100 000 population in parts of Europe, including Scandinavia, while rates for paediatric UC are often slightly lower than for CD. Prevalence reported for CD ranged from 8.2 per 100 000 to approximately 60 and, for UC, from 8.3 to approximately 30. CONCLUSIONS The incidence of paediatric IBD continues to increase throughout Europe. There is stronger evidence of a north-south than an east-west gradient in incidence across Europe. Further prospective studies are needed, preferably multinational and based on IBD registries, using standardized definitions, methodology and timescales.

Abstract
Background The goal of the present study was to investigate the effects of TAK-242 on the gut microbiota and the TLR4/JAK2/STAT3 signaling pathway in mice with dextran sulfate sodium (DSS)-induced colitis. Results At the phylum level, Bacteroidetes, Firmicutes, Actinobacteria, Cyanobacteria, Epsilonbacteraeota and Proteobacteria were the primary microbiota in the five groups. TAK-242 treatment significantly enhanced Verrucomicrobia and Actinobacteria; significantly decreased Cyanobacteria, Epsilonbacteraeota and Proteobacteria; and particularly promoted the growth of Akkermansia. TAK-242 markedly alleviated DSS-induced colitis symptoms and colonic lesions by promoting IL-10 release, inhibiting IL-17 release, downregulating TLR4 and JAK2/STAT3 mRNA and protein expression and increasing JAK2/STAT3 phosphorylation. Conclusion TAK-242 modulates the structure of the gut microbiota in colitis and may be a novel therapeutic candidate for ulcerative colitis.

Abstract
Background Apocynum venetum leaves are used as a kind of phytomedicine and the main ingredient in some traditional Chinese medicine products for the relief of colitis. To understand the bioactive constituents of A. venetum L., we did a phytochemistry study and investigated anti-Inflammatory effects of compounds and explored the underlying mechanisms. Methods We isolated compounds from ethanol extract of A. venetum L. leaf and detected the most effective compound by NO inhibition assay. We investigated anti-Inflammatory effects on dextran sulfate sodium (DSS)-induced colitis mice and lipopolysaccharide (LPS)-stimulated RAW264.7 cells. The disease activity index was determined by scores of body weight loss, diarrhea and rectal bleeding; histological damage was analyzed by H&E staining; macrophages change in the colon were analyzed by immunohistochemistry (IHC); myeloperoxidase activity was measured by myeloperoxidase assay kits; levels of proinflammatory cytokines were determined by qPCR and ELISA; protein production such as COX-2, iNOS, STAT3 and ERK1/2 were determined by western blotting. Results We isolated uvaol from ethanol extract of A. venetum L. leaf and found uvaol has excellent potential of inhibiting NO production. We further found uvaol could attenuate disease activity index (DAI), colon shortening, colon injury, and colonic myeloperoxidase activity in DSS-induced colitis mice. Moreover, uvaol significantly reduces mRNA expression and production of pro-inflammatory cytokines (TNF-α, IL-6, IL-1β, and MCP-1) and infiltration of macrophages in colonic tissues of colitis mice. Studies on LPS challenged murine macrophage RAW246.7 cells also revealed that uvaol reduces mRNA expression and production of pro-inflammatory cytokines and mediators. Mechanically, uvaol inhibits the pro-inflammatory ERK/STAT3 axis in both inflamed colonic tissues and macrophages. Conclusions A. venetum leaf contains uvaol and uvaol has potent anti-inflammatory effects on DSS-induced experimental colitis and LPS-stimulated RAW264.7 macrophage cells. These results suggest uvaol is a prospective anti-inflammatory agent for colonic inflammation.

Abstract
Host sensing in the gut microbiota has been crucial in the regulation of intestinal homeostasis. Although inflammatory bowel diseases (IBDs), multifactorial chronic inflammatory conditions of the gastrointestinal tract, have been associated with intestinal dysbiosis, the detailed interactions between host and gut microbiota are still not completely understood. Enteroendocrine cells (EECs) represent 1% of the intestinal epithelium. Accumulating evidence indicates that EECs are key sensors of gut microbiota and/or microbial metabolites. They can secrete cytokines and peptide hormones in response to microbiota, either in traditional endocrine regulation or by paracrine impact on proximal tissues and/or cells or via afferent nerve fibers. Enteroendocrine cells also play crucial roles in mucosal immunity, gut barrier function, visceral hyperalgesia, and gastrointestinal (GI) motility, thereby regulating several GI diseases, including IBD. In this review, we will focus on EECs in sensing microbiota, correlating enteroendocrine perturbations with IBD, and the underlying mechanisms.

Abstract
Background and aims The effect of smoking on the risk of developing inflammatory bowel diseases (IBD) may be heterogeneous across ethnicity and geography. Although trends in smoking for the general population are well described, it is unknown whether these can be extrapolated to the IBD cohort. Smoking prevalence trends specific to the global IBD cohort over time have not been previously reported. This is a systematic review of smoking prevalence specific to the IBD cohort across geography. Methods A systematic literature search was conducted on Medline and Embase from January 1st 1946 to April 5th 2018 to identify population-based studies assessing the prevalence of smoking at diagnosis in inception cohorts of Crohn’s disease(CD) or ulcerative colitis(UC). Studies that did not report smoking data from time of diagnosis or the year of IBD diagnosis were excluded. Prevalence of smoking in IBD was stratified by geography and across time. Results We identified 56 studies that were eligible for inclusion. Smoking prevalence data at diagnosis of CD and UC was collected from twenty and twenty-five countries respectively. Never-smokers in the newly diagnosed CD population in the West has increased over the last two decades, especially in the United Kingdom and Sweden; +26.6% and +11.2% respectively. Never-smokers at CD diagnosis in newly industrialised nations have decreased over the 1990s and 2000s; China (-19.36%). Never-smokers at UC diagnosis also decreased in China; -15.4%. The former-smoker population at UC diagnosis in China is expanding; 11%(1990–2006) to 34%(2011–2013). Conclusion There has been a reduction in the prevalence of smoking in the IBD cohort in the West. This is not consistent globally. Although, smoking prevalence has decreased in the general population of newly industrialised nations, this remains an important risk factor with longer term outcomes awaiting translation in both UC and CD.

Abstract
BACKGROUND Inflammatory bowel disease (IBD) is a chronic disease of the intestinal tract in which excessive activation of inflammatory response is correlated. Cyanidin-3-O-glucoside (C3G) is a powerful anti-inflammatory agent, widely existing in fruits and vegetables. However, the role of C3G has rarely been investigated in dextran sulfate sodium (DSS)-induced colitis. METHODS In an attempt to elucidate the possible mechanism of IBD and develop new efficient therapeutic methods for colitis, we evaluated the effects of C3G on DSS-induced colitis. DSS-induced colitic C57BL/6 mice were intraperitoneal injected with 1ug C3G or phosphate buffer every 2 days, a total of 3 times; the changes in macrophages and regular T cells were analyzed by flow cytometry and immunofluorescence. Cytokines and chemokines were measured by real-time quantitative polymerase chain reaction. RESULTS The results showed that C3G treatment did not cause changes in body weight and colon length as much as those of DSS-treated mice only. Cytokine expression levels such as interleukin (IL)- 6, IL-1β, IL-18, tumor necrosis factor α, interferon γ (IFN γ) in colons and mesenteric lymph nodes (mLNs) from C3G-treated mice were lower than those from colitic mice. Meanwhile, C3G injection inhibited the decrease in CCL22 levels and Tregs induction in colitic mice. Furthermore, the activation of macrophages by LPS and increase of CD169+ cells induced by type I IFN could be inhibited by C3G directly in vitro. CONCLUSIONS The study is the first to demonstrate strong effects of C3G to alleviate DSS-induced colonic damage in mice. The effect of C3G on DSS-induced colitis clearly showed a decrease of CD169+ macrophages in both the colon and mLNs. An increase of CD169+ cells induced by type I IFN could be inhibited by C3G. All these data suggest that the role of C3G in colitic inflammation was mediated at least partially by CD169+ cells and the type I IFN pathway.

Abstract
PURPOSE OF REVIEW Once thought a disease of Western civilizations, the inflammatory bowel diseases (IBD) impose a global burden, now penetrating populations in Asia, Africa, and South America. We summarize similarities and differences in the epidemiology of IBD globally, highlighting gaps in knowledge where future study is needed. RECENT FINDINGS While incidence of IBD is stabilizing (or even decreasing) in many westernized regions, prevalence continues to grow due to a young age of onset and low mortality. In newly westernized regions, IBD is beginning to penetrate populations comparable to the rapid increases seen in North America, Europe, and Oceania in the last century. IBD imposes a significant fiscal and resource burden on healthcare systems. As global prevalence of these diseases continues to increase, we desperately need to anticipate the future burden to proactively prepare our healthcare systems for the challenges of increased patient load and aging populations with comorbid conditions and longer disease course.

Abstract
Background The Faroe Islands currently have the highest recorded inflammatory bowel disease (IBD) incidence in the world. Objective This study investigated environmental risk factors for IBD in the Faroese population. Methods Environmental exposure data including lifestyle risk factors and neurotoxicants collected for over 30 years were retrieved from the Children's Health and the Environment in the Faroes (CHEF) cohorts including mainly mother–child pairs, with exposure data collected from pregnant mothers. For lifestyle risk factors, the incidence of IBD and ulcerative colitis (UC) was calculated as the rate ratio (RR) with 95% confidence intervals (CI) in exposed versus non-exposed persons. For neurotoxicants RR was calculated for persons with high versus low exposure. Results Six cohorts included 5698 persons with complete follow-up data and at least one exposure, and 37 were diagnosed with IBD. For pilot whale/blubber, the RR was 1.02 (95% CI, 0.48–2.18); RR of 1.01 for fish (95% CI, 0.35–2.91); and of the pollutants studied, a statistical significantly increased risk was found for 1,1,1,-trichloro-2,2-bis-(p-chlorophenyl) ethane (p,p'-DDT); RR 3.04 (95% CI, 1.12–8.30). RRs were 1.96 (95% CI, 1.03–3.73) for smoking and 1.10 (95% CI, 0.55–2.19) for alcohol intake. Conclusion The high IBD incidence is unlikely to be caused by special dietary habits or by environmental pollutants.

Abstract
The gastrointestinal system where inflammatory bowel disease occurs is central to the immune system where the innate and the adaptive/acquired immune systems are balanced in interactions with gut microbes under homeostasis conditions. This article overviews the high-throughput research screening on multifactorial interplay between genetic risk factors, the intestinal microbiota, urbanization, modernization, Westernization, the environmental influences and immune responses in the etiopathogenesis of inflammatory bowel disease in humans. Inflammatory bowel disease is an expensive multifactorial debilitating disease that affects thousands new people annually worldwide with no known etiology or cure. The conservative therapeutics focus on the established pathology where the immune dysfunction and gut injury have already happened but do not preclude or delay the progression. Inflammatory bowel disease is evolving globally and has become a global emergence disease. It is largely known to be a disease in industrial-urbanized societies attributed to modernization and Westernized lifestyle associated with environmental factors to genetically susceptible individuals with determined failure to process certain commensal antigens. In the developing nations, increasing incidence and prevalence of inflammatory bowel disease (IBD) has been associated with rapid urbanization, modernization and Westernization of the population. In summary, there are identified multiple associations to host exposures potentiating the landscape risk hazards of inflammatory bowel disease trigger, that include: Western life-style and diet, host genetics, altered innate and/or acquired/adaptive host immune responses, early-life microbiota exposure, change in microbiome symbiotic relationship (dysbiosis/dysbacteriosis), pollution, changing hygiene status, socioeconomic status and several other environmental factors have long-standing effects/influence tolerance. The ongoing multipronged robotic studies on gut microbiota composition disparate patterns between the rural vs. urban locations may help elucidate and better understand the contribution of microbiome disciplines/ecology and evolutionary biology in potentially protecting against the development of inflammatory bowel disease.

AIM To investigate inflammatory bowel disease (IBD) register-based subtype classifications over a patient's disease course and over time. METHODS We examined International Classification of Diseases coding in patients with ≥2 IBD diagnostic listings in the National Patient Register 2002-2014 (n = 44,302). RESULTS 18% of the patients changed diagnosis (17% of adults, 29% of children) during a median follow-up of 3.8 years. Of visits with diagnoses of Crohn's disease (CD) or ulcerative colitis (UC), 97% were followed by the same diagnosis, whereas 67% of visits with diagnosis IBD-unclassified (IBD-U) were followed by another IBD-U diagnosis. Patients with any diagnostic change changed mostly once (47%) or twice (31%), 39% from UC to CD, 33% from CD to UC and 30% to or from IBD-U. Using a classification algorithm based on the first two diagnoses ('incident classification'), suited for prospective cohort studies, the proportion adult patients with CD, UC, and IBD-U 2002-2014 were 29%, 62%, and 10% (43%, 45%, and 12% in children). A classification model incorporating additional information from surgeries and giving weight to the last 5 years of visits ('prevalent classification'), suited for description of a study population at end of follow-up, classified 31% of adult cases as CD, 58% as UC and 11% as IBD-U (44%, 38%, and 18% in children). CONCLUSIONS IBD subtype changed in 18% during follow-up. The proportion with CD increased and UC decreased from definition at start to end of follow-up. IBD-U was more common in children.

Abstract
Microbial dysbiosis characterized by alterations in the structure and function of the gut microbiome has long been implicated in the pathogenesis of inflammatory bowel disease (IBD). To date, most human IBD microbiome studies are focused on microbial composition rather than function, however, with the latest technical advancements complemented by the rapidly dropping costs, studies focusing on the functional aspects of microbial dysbiosis are on the rise. Several compelling and complimentary pieces of evidence support the notion that the gut microbiome and their metabolites play an important role in the development of IBD. Data from preclinical studies overwhelmingly support the notion that changes in the gut microbiome causally underlie IBD pathogenesis. Hence, there is considerable interest in modulating the state and function of the gut microbiome to achieve therapeutic benefits. While the causal potential of the gut microbiome remains an active area of current research in the clinical setting, accumulating correlative evidence support the view that microbial dysbiosis parallels increased incidence of IBD. In this review, we intend to provide a brief overview of the current human IBD microbiome findings, describe the cause-effect relationships between the gut microbiome and IBD, and discuss the possibility of using microbiome-based approaches in the diagnosis, therapy, and management of disease. In addition, the potential role of microbiome-based interventions in the treatment of human IBD is also discussed.

Abstract
BACKGROUND/AIMS Incidences of inflammatory bowel diseases (IBDs), ulcerative colitis (UC), and Crohn's disease (CD), have been increasing in Asia. In this study, we report the relevant clinical characteristics and determined the epidemiological trend of IBD in Taiwan from 2001 to 2015. METHODS A retrospective study was conducted to analyze data recorded from January 2001 through December 2015 in the registered database compiled by the National Health Insurance and provided by the Ministry of Health and Welfare, Taiwan. RESULTS A total of 3,806 patients with catastrophic IBD illness were registered from 2001 to 2015 in Taiwan (CD, 919; UC, 2,887). The crude incidence of CD increased from 0.17/100,000 in 2001 to 0.47/100,000 in 2015, whereas that of UC increased from 0.54/100,000 in 2001 to 0.95/100,000 in 2015. The prevalence of CD increased from 0.6/100,000 in 2001 to 3.9/100,000 in 2015, whereas that of UC increased from 2.1/100,000 in 2001 to 12.8/100,000 in 2015. The male-to-female ratio in the study sample was 2.19 for CD and 1.62 for UC. The median age of those registered with CD was lower than that of those registered for UC: 38.86 and 44.86 years, respectively. A significantly greater increase in CD incidence rate was identified among 20 to 39-year-old compared with other age groups. CONCLUSIONS Using Taiwan's nationwide insurance database, we determined that the number of patients with CD increased more rapidly during the study period than the number of patients with UC, especially among age 20 to 39-year-old, resulting in a decreased UC-to-CD ratio.

Abstract
BACKGROUND & AIMS Although the incidence of inflammatory bowel diseases (IBDs) varies with age, few studies have examined variations between the sexes. We therefore used population data from established cohorts to analyze sex differences in IBD incidence according to age at diagnosis. METHODS We identified population-based cohorts of patients with IBD for which incidence and age data were available (17 distinct cohorts from 16 regions of Europe, North America, Australia, and New Zealand). We collected data through December 2016 on 95,605 incident cases of Crohn's disease (CD) (42,831 male and 52,774 female) and 112,004 incident cases of ulcerative colitis (UC) (61,672 male and 50,332 female). We pooled incidence rate ratios of CD and UC for the combined cohort and compared differences according to sex using random effects meta-analysis. RESULTS Female patients had a lower risk of CD during childhood, until the age range of 10-14 years (incidence rate ratio, 0.70; 95% CI, 0.53-0.93), but they had a higher risk of CD thereafter, which was statistically significant for the age groups of 25-29 years and older than 35 years. The incidence of UC did not differ significantly for female vs male patients (except for the age group of 5-9 years) until age 45 years; thereafter, men had a significantly higher incidence of ulcerative colitis than women. CONCLUSIONS In a pooled analysis of population-based studies, we found age at IBD onset to vary with sex. Further studies are needed to investigate mechanisms of sex differences in IBD incidence.

Abstract
In the twenty first century, the changing epidemiology of inflammatory bowel disease (IBD) globally with increasing disease incidence across many countries relates to the altered gut microbiota, due to a combinatorial effect of environmental factors, human immune responses and genetics. IBD is a gastrointestinal disease associated with a gut microbial dysbiosis, including an expansion of facultative anaerobic bacteria of the family Enterobacteriaceae. Advances in high-throughput sequencing enable us to entangle the gut microbiota in human health and IBD beyond the gut bacterial microbiota, expanding insights into the mycobiota, virobiota and helminthes. Caudovirales (viruses) and Basidiomycota, Ascomycota, and Candida albicans (fungi) are revealed to be increased in IBD. The deconvolution of the gut microbiota in IBD lays the basis for unveiling the roles of these various gut microbiota components in IBD pathogenesis and being conductive to instructing on future IBD diagnosis and therapeutics. Here we comprehensively elucidate the alterations in the gut microbiota in IBD, discuss the effect of diets in the gut microbiota in relation to IBD, and illustrate the potential of manipulation of gut microbiota for IBD therapeutics. The therapeutic strategy of antibiotics, prebiotics, probiotics and fecal microbiota transplantation will benefit the effective application of precision microbiome manipulation in IBD.

Abstract
AIM To perform a comprehensive review and provide an up-to-date synopsis of the incidence and trends of inflammatory bowel disease (IBD). METHODS We systematically searched the MEDLINE (source PubMed), EMBASE and Cochrane Library databases in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines (period: 1985-2018) to identify studies reporting population-based data on the incidence of pediatric-onset (< 19 years at diagnosis) IBD in full manuscripts. Two authors carried out screening and data extraction. Choropleth interactive maps and temporal trends were used to illustrate the international differences and incidences of and changes in IBD and subtypes. RESULTS In total, one hundred forty studies reporting data from 38 countries were considered in this review. The highest annual pediatric incidences of IBD were 23/100000 person-years in Europe, 15.2/100000 in North America, and 11.4/100000 in Asia/the Middle East and Oceania. The highest annual incidences of Crohn's disease (CD) were 13.9/100000 in North America and 12.3/100000 in Europe. The highest annual incidences of ulcerative colitis (UC) were 15.0/100000 in Europe and 10.6/100000 in North America. The highest annual incidences of IBD-unclassified (IBD-U) were 3.6/100000 in Europe and 2.1/100000 in North America. In the time-trend analyses, 67% of CD, 46% of UC and 11% of IBD-U studies reported an increasing incidence (P < 0.05). The risk of IBD is increasing among first-generation of migrant populations. CONCLUSION Globally, the incidence of IBD varies greatly by geographical areas. The steadily increasing incidence of pediatric IBD over time indicates its emergence as a global disease, suggesting that studies should investigate the environmental risk factors among pediatric cohorts.

Abstract
In the 21st century, urbanization represents a major demographic shift in developed and developing countries. Rapid urbanization in the developing world has been associated with an increasing incidence of several autoimmune diseases, including IBD. Patients with IBD exhibit a decrease in the diversity and richness of the gut microbiota, while urbanization attenuates the gut microbial diversity and might have a role in the pathogenesis of IBD. Environmental exposures during urbanization, including Westernization of diet, increased antibiotic use, pollution, improved hygiene status and early-life microbial exposure, have been shown to affect the gut microbiota. The disparate patterns of the gut microbiota composition in rural and urban areas offer an opportunity to understand the contribution of a 'rural microbiome' in potentially protecting against the development of IBD. This Perspective discusses the effect of urbanization and its surrogates on the gut microbiome (bacteriome, virome, mycobiome and helminths) in both human health and IBD and how such changes might be associated with the development of IBD.

Abstract
PURPOSE OF REVIEW Inflammatory bowel diseases (IBD), which include Crohn's disease (CD) and ulcerative colitis (UC), are chronic, relapsing diseases with unknown etiologies. The purpose of this review is to present the natural disease course evidenced in the latest epidemiology data. RECENT FINDINGS The prevalence of IBD is rapidly increasing, affecting five million patients worldwide with the highest incidence observed in Northern Europe and Northern America. It has been shown that both CD and UC patients are at an increased risk for developing cancer of the gastrointestinal tract compared to the general population. Though the disease course of IBD is unpredictable, the rate of surgical treatment has declined potentially as a consequence of the introduction of immunomodulators and new biologic treatment options. Treatments with biological agents and/or immunosuppressive drugs as well as disease monitoring with eHealth devices seem to have a positive impact on the disease course. However, long-term follow-up studies are still lacking and therefore no reliable conclusions can be drawn as of yet. Medical compliance is paramount in the treatment of IBD, and continuous research focusing on approaches that increase compliance is also necessary.

Regulatory role of NKG2D+ NK cells in intestinal lamina propria by secreting double-edged Th1 cytokines in ulcerative colitis. Oncotarget 2017; 8:98945-98952.

Abstract
The role of intestinal lamina propria (LP) NKG2D+ NK cells is unclear in regulating Th1/Th2 balance in ulcerative colitis (UC). In this study, we investigated the frequency of LP NKG2D+ NK cells in DSS-induced colitis model and intestinal mucosal samples of UC patients, as well as the secretion of Th1/Th2/Th17 cytokines in NK cell lines after MICA stimulation. The role of Th1 cytokines in UC was validated by bioinformatics analysis. We found that DSS-induced colitis in mice was characterized by a Th2-mediated process. In acute phrase, the frequency of LP NKG2D+ lymphocytes increased significantly and decreased in remission, while the frequency of LP NKG2D+ NK cells decreased significantly in acute phase and increased in remission. No obvious change was found in the frequency of total LP NK cells. Similarly, severe UC patients had a higher expression of mucosal NKG2D and a lower number of NKG2D+ NK cells than mild to moderate UC. In NK cell lines, the MICA stimulation could induce a predominant secretion of Th1 cytokines (TNF, IFN-γ). Furthermore, in bioinformatics analysis, mucosal Th1 cytokine of TNF, showed a double-edged role in UC when compared to the Th1-mediated disease of Crohn's colitis. In conclusion, LP NKG2D+ NK cells partially played a regulatory role in UC through secreting Th1 cytokines to regulate the Th2-predominant Th1/Th2 imbalance, despite of the concomitant pro-inflammatory effects of Th1 cytokines.

CD169 Expressing Macrophage, a Key Subset in Mesenteric Lymph Nodes Promotes Mucosal Inflammation in Dextran Sulfate Sodium-Induced Colitis. Front Immunol 2017; 8:669.

Abstract
Inflammatory bowel disease (IBD) including Crohn’s disease (CD) and ulcerative colitis is a relapsing-remitting illness. Patients with long-standing extensive colitis are easy to develop colorectal cancer (CRC). The increasing incidence of IBD and a substantial increase in the risk of CRC make the necessity to pay more attention on the regulation of inflammation especially by specific macrophages subset. The present study reported that a key subset of sinus macrophage expressing CD169 in mesenteric lymph nodes (mLNs) played an essential role in promoting mucosal inflammation. The results revealed that the subset expressing CD169 in mLNs increased significantly during the dextran sulfate sodium (DSS)-induced colitis. The colitic symptoms were alleviated in CD169-diphtheria toxin receptor (DTR) mice at least partially due to the deletion of CD169+ macrophages in mLNs. In addition, the levels of inflammatory cytokines as well as the percentage of Th17 cells in mLNs from CD169-DTR mice were much lower than those from WT mice with DSS-induced colitis. Further experiment in vitro demonstrated that the supernatant from whole cells of mLNs or colon tissues could promote the production of inflammatory factors by mLN cells or colon tissues from CD169-DTR mice. These results could be explained by the cell sorting result that CD11b+CD169+ macrophages expressed higher level of inflammatory factors directly. All these data indicated that CD169+ sinus macrophage in mLNs played an essential role on regulating mucosal inflammation.

Abstract
OBJECTIVES Glucocorticoid (GC) use is widespread and associated with many adverse effects. Thus, it is important to ascertain GC utilisation patterns. In this study, we examined the annual prevalence of prescription users and amount of use of systemic GCs. DESIGN Population-wide prevalence study. SETTING The primary healthcare and hospital sectors in Denmark from 1999 to 2015. RESULTS Approximately 3% of the Danish population redeemed at least one prescription for a systemic GC annually between 1999 and 2015, with annual prevalence remaining constant over the period. However, after adjusting for age and sex, we observed a decrease in annual prevalence from 1999 to 2015, with a prevalence ratio of 0.92 (95% CI 0.91 to 0.92). Annual prevalence was highest among the elderly (7.0%-8.2% among persons 65-79 years of age and 8.4%-10% among persons 80+ years of age). Prednisolone was the most frequently redeemed systemic GC, with annual prevalence increasing from 1.4% to 2.1% during the 1999-2015 period. The amount of systemic GCs provided to the hospital sector increased from 2.3 defined daily doses (DDD)/1000 inhabitants/day in 1999 to 3.5 DDD/1000 inhabitants/day in 2015, while the amount provided to the primary healthcare sector remained constant in the range of 10-11 DDD/1000 inhabitants/day. CONCLUSION We found a high prevalence of systemic GC use of 3% with a remarkably high prevalence in elderly of up to 10%, wherefore continued awareness of its effects is mandated.

Hammer T, Lophaven SN, Nielsen KR, von Euler‐Chelpin M, Weihe P, Munkholm P, Burisch J, Lynge E. Inflammatory bowel diseases in Faroese-born Danish residents and their offspring: further evidence of the dominant role of environmental factors in IBD development. Aliment Pharmacol Ther 2017; 45:1107-1114. [PMID: 28176348 PMCID: PMC5396334 DOI: 10.1111/apt.13975] [Citation(s) in RCA: 15] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/27/2016] [Revised: 11/24/2016] [Accepted: 01/16/2017] [Indexed: 12/11/2022]
Abstract
BACKGROUND The incidence of inflammatory bowel disease (IBD) is record high in the Faroe Islands, and many Faroese emigrate to Denmark, where the IBD incidence is considerably lower. AIM To study the IBD incidence in first-, second- and third-generation immigrants from the Faroe Islands to Denmark to assess the extent to which the immigrants adopt the lower IBD incidence of their new home country. METHODS Data on Faroese-born Danish residents and their children were retrieved from the Danish Central Population Register for 1980-2014. Incident IBD cases were identified from the Danish National Patient Register. Standardised Incidence Ratios (SIRs) were used to compare the IBD risk in immigrants with that of Danes. 95% confidence intervals (CI) were calculated using the square-root transform. RESULTS First-generation Faroese immigrants had a higher IBD incidence than Danes, SIR 1.25 (95% CI, 0.97-1.59) for men and 1.28 (95% CI, 1.05-1.53) for women. This excess risk derived from ulcerative colitis (UC), SIR 1.44 (95% CI, 1.10-1.87) for men and 1.36 (95% CI, 1.09-1.68) for women. No excess risk was found for Crohn's disease (CD). The UC risk was nearly doubled during the immigrants' first 10 years in Denmark; SIR 2.13 (95% CI, 1.52-2.92) for men and 1.63 (95% CI, 1.19-2.18) for women. CONCLUSIONS Although some impact of genetic dilution cannot be excluded, our findings indicate importance of gene-environment interplay in UC, as the excess UC risk in Faroese immigrants to Denmark disappeared over time and over one generation in men and over two generations in women.
