Abstract
Inflammatory bowel disease (IBD), mainly including ulcerative colitis and Crohn's disease, imposes a huge medical and economic burden worldwide. Recently, the diagnosis, treatment, and surveillance of IBD have advanced rapidly, which has changed the epidemiology, cancer risk, and surgery risk of IBD. Here, we reviewed the recent literature on the epidemiology, IBD-related cancer, and IBD-related surgery. We created a choropleth map to show the worldwide incidence trend for Crohn's disease and ulcerative colitis. We also found that the cancer risk and surgery risk of IBD are declining and discussed some risk factors associated with them. Based on the recent trend, we proposed several suggestions and hoped to reduce the global burden of IBD as far as possible.

Abstract
AIM Crohn's disease has debilitating effects on patients' quality of life. Currently, there are limited data on the effect of anastomotic configuration on health-related quality of life after ileocaecal resection for Crohn's disease. This study aimed to assess the impact of Kono-S anastomosis on quality of life after ileocolic resection, compared to the conventional side-to-side anastomosis. METHOD Patients with primary or recurrent Crohn's disease participating in the ongoing SuPREMe-CD trial were interviewed about quality of life using the Inflammatory Bowel Disease Questionnaire (IBDQ). The primary endpoint was disease-specific quality of life, assessed with IBDQ. Secondary outcomes were quality of life related to bowel symptoms, systemic symptoms, social function and emotional function. RESULTS Of the 94 patients included, 51 (54%) received the conventional side-to-side anastomosis and 43 (46%) the Kono-S anastomosis. Demographics were comparable between the two groups. The IBDQ was assessed at a mean follow-up of 54.0 ± 18.7 months from surgical intervention. The mean total IBDQ score was 155.1 ± 28.07 in the conventional group and 163.8 ± 25.23 in the Kono-S group (P = 0.11). When considering bowel symptoms and social function, mean scores were 50.7 and 23.5 in the conventional group, and 56.3 and 26.5 in the Kono-S group (P = 0.002 and P = 0.02, respectively). Kono-S anastomosis was independently associated with improved quality of life regarding bowel symptoms (P = 0.006) and social function (P = 0.03) after correcting for other confounding factors on linear regression analysis. CONCLUSION Compared to conventional side-to-side anastomosis, patients with Kono-S anastomosis presented significantly better bowel symptoms and social function scores at 54 months after surgery.

Abstract
Picroside III (Pic), an iridoid glycoside derived from Picrorhiza scrophulariiflora, exhibits therapeutic potential in mending damage to the intestinal mucosa. This study aimed to explore Pic's regulatory impact on intestinal inflammation and the gut microbiota in mice with dextran sulfate sodium (DSS)-induced colitis. The findings revealed that pretreatment with Pic mitigated the DSS-induced escalation of the disease activity index (DAI), alleviated intestinal damage, and attenuated intestinal inflammation in mice. RNA-seq analysis, complemented by experimental validation, elucidated that Pic significantly hindered Akt phosphorylation in the colon tissues of colitis-afflicted mice. Furthermore, 16S rRNA sequencing demonstrated that Pic pretreatment effectively rectified microbial dysbiosis in colitis mice by elevating the abundance of Lactobacillus murinus and Lactobacillus gasseri. These observations suggest that Pic's efficacy in colitis treatment stems from its inhibition of intestinal inflammation via the suppression of the PI3K-Akt pathway and modulation of gut microbiota. This study contributes novel scientific insights into the potential application of Pic in the management of inflammatory bowel disease (IBD).

Sci Rep 2023; 13:19198. [PMID: 37932491 PMCID: PMC10628307 DOI: 10.1038/s41598-023-46714-8] [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: 06/14/2023] [Accepted: 11/03/2023] [Indexed: 11/08/2023] Open
Abstract
Crohn's disease (CD) is a chronic inflammatory bowel disease. An imbalanced microbiome (dysbiosis) can predispose to many diseases including CD. The role of oral dysbiosis in CD is poorly understood. We aimed to explore microbiome signature and dysbiosis of the salivary microbiome in CD patients, and correlate microbiota changes to the level of inflammation. Saliva samples were collected from healthy controls (HC) and CD patients (n = 40 per group). Salivary microbiome was analyzed by sequencing the entire 16S rRNA gene. Inflammatory biomarkers (C-reactive protein and calprotectin) were measured and correlated with microbiome diversity. Five dominant species were significantly enriched in CD, namely Veillonella dispar, Megasphaera stantonii, Prevotella jejuni, Dolosigranulum pigrum and Lactobacillus backii. Oral health had a significant impact on the microbiome since various significant features were cariogenic as Streptococcus mutans or periopathogenic such as Fusobacterium periodonticum. Furthermore, disease activity, duration and frequency of relapses impacted the oral microbiota. Treatment with monoclonal antibodies led to the emergence of a unique species called Simonsiella muelleri. Combining immunomodulatory agents with monoclonal antibodies significantly increased multiple pathogenic species such as Salmonella enterica, Escherichia coli, Klebsiella pneumoniae and Pseudomonas aeruginosa. Loss of diversity in CD was shown by multiple diversity indices. There was a significant negative correlation between gut inflammatory biomarkers (particularly calprotectin) and α-diversity, suggesting more inflammation associated with diversity loss in CD. Salivary dysbiosis was evident in CD patients, with unique microbiota signatures and perturbed species that can serve as disease biomarkers or potential targets for microbiota modulation. The interplay of various factors collectively contributed to dysbiosis, although each factor probably had a unique effect on the microbiome. The emergence of pathogenic bacteria in the oral cavity of CD patients is alarming since they can disturb gut homeostasis and induce inflammation by swallowing, or hematogenous spread of microbiota, their metabolites, or generated inflammatory mediators.

Abstract
BACKGROUND Stenosis is one of the most common complications in patients with Crohn's disease (CD). Endoscopic balloon dilation (EBD) is the treatment of choice for a short stenosis adjacent to the anastomosis from previous surgery. Self-expandable metal stents (SEMS) may be a suitable treatment option for longer stenoses. To date, however, there is no scientific evidence as to whether endoscopic (EBD/SEMS) or surgical treatment is the best approach for de novo or primary stenoses that are less than 10 cm in length. METHODS/DESIGN Exploratory study as "proof-of-concept", multicentre, open-label, randomized trial of the treatment of de novo stenosis in the CD; endoscopic treatment (EBD/SEMS) vs surgical resection (SR). The type of endoscopic treatment will initially be with EDB; if a therapeutic failure occurs, then a SEMS will be placed. We estimate 2 years of recruitment and 1 year of follow-up for the assessment of quality of life, costs, complications, and clinical recurrence. After the end of the study, patients will be followed up for 3 years to re-evaluate the variables over the long term. Forty patients with de novo stenosis in CD will be recruited from 15 hospitals in Spain and will be randomly assigned to the endoscopic or surgical treatment groups. The primary aim will be the evaluation of the patient quality of life at 1 year follow-up (% of patients with an increase of 30 points in the 32-item Inflammatory Bowel Disease Questionnaire (IBDQ-32). The secondary aim will be evaluation of the clinical recurrence rate, complications, and costs of both treatments at 1-year follow-up. DISCUSSION The ENDOCIR trial has been designed to determine whether an endoscopic or surgical approach is therapeutically superior in the treatment of de novo stenosis in CD.

Abstract
Inflammatory bowel disease can be caused by the dysfunction of the intestinal mucosal barrier and dysregulation of gut microbiota. Traditional treatments use drugs to manage inflammation with possible probiotic therapy as an adjuvant. However, current standard practices often suffer from metabolic instability, limited targeting and result in unsatisfactory therapeutic outcomes. Here we report on artificial-enzyme-modified Bifidobacterium longum probiotics for reshaping a healthy immune system in inflammatory bowel disease. Probiotics can promote the targeting and retention of the biocompatible artificial enzymes to persistently scavenge elevated reactive oxygen species and alleviate inflammatory factors. The reduced inflammation caused by artificial enzymes improves bacterial viability to rapidly reshape the intestinal barrier functions and restore the gut microbiota. The therapeutic effects are demonstrated in murine and canine models and show superior outcomes to traditional clinical drugs.

Abstract
Background Data on the performance of newer biologics in patients with fistulizing Crohn's disease (CD) are limited. Objective Our study's objective was to evaluate the response to ustekinumab (UST) and vedolizumab (VDZ) in patients with fistulizing CD. Design Retrospective cohort. Methods We used natural language processing of electronic medical record data to identify a retrospective cohort of individuals with fistulizing CD at a single academic tertiary-care referral center and then performed a chart review. Individuals were eligible for inclusion if a fistula was present at the time of UST or VDZ initiation. Outcomes included medication discontinuation, surgical intervention, development of a new fistula, and fistula closure. Groups were compared with unadjusted analyses and competing risk analyses using multi-state survival models. Results In all, 68 patients were included (48 UST and 20 VDZ). Most patients had one fistula (79%) and had prior anti-tumor necrosis factor-α treatment (98% in UST group, 80% in VDZ group, p = 0.01). VDZ was significantly more likely to be discontinued than UST (p < 0.0001), most frequently due to inadequate clinical response. Those on UST had a longer median time to surgery for CD than those on VDZ (p = 0.008). In those without surgical fistula repair, 79% on UST and 100% on VDZ still had an active fistula at 1 year (p = 0.30). Conclusion In individuals with fistulizing CD, our data suggest that UST has better clinical utility than VDZ based on lower rates of discontinuation, though the sample size is small. These findings highlight the importance of further research on the treatment of perianal fistulizing Crohn's disease.

Abstract
Gastrointestinal (GI) endoscopy has transformed over the years in scope, safety, accuracy, acceptability, and cost effectiveness of the clinical practice. There has been a reduction in the superiority of the endoscopic devices as innovations have taken place and increased the diagnostic values with certain limitations. There are particular difficulties in striking a balance between the development of new technology and the device's acceptance. The wide use of endoscopy for investigating GI lesions and diagnosis has led to an increase in more advanced methods and their broad application. It can simultaneously diagnose pre-malignant and malignant lesions, and newer interventions have made the biopsy specimen uptake possible. In this review article, we focus on the more recent roles, indications, applications, and usage of the innovative methods of endoscopy.

Abstract
Artificial intelligence (AI) is assuming an increasingly important and central role in several medical fields. Its application in endoscopy provides a powerful tool supporting human experiences in the detection, characterization, and classification of gastrointestinal lesions. Lately, the potential of AI technology has been emerging in the field of inflammatory bowel disease (IBD), where the current cornerstone is the treat-to-target strategy. A sensible and specific tool able to overcome human limitations, such as AI, could represent a great ally and guide precision medicine decisions. Here we reviewed the available literature on the endoscopic applications of AI in order to properly describe the current state-of-the-art and identify the research gaps in IBD at the dawn of 2022.

Abstract
Perianal fistulizing Crohn's disease represents a severe phenotype associated with significant morbidity. Patients with perianal fistulizing disease are more likely to have a severe disease course and have significant reductions in quality of life. Moreover, these patients are at risk for the development of distal rectal and anal cancers. Given the complexity and severity of this patient group, the management of perianal Crohn's disease must be undertaken by a multidisciplinary team. The gastroenterologist and colorectal surgeon play a critical role in the diagnosis and management of perianal fistulizing disease. An examination under anesthesia provides critical information and is an essential part of the work-up of complex perianal fistulas. The radiologist also plays a central role in characterizing anatomy and assessing response to treatment. Several imaging modalities are available for these patients with magnetic resonance imaging as the imaging modality of choice. Perianal disease developing after ileal pouch-anal anastomosis represents a particularly challenging form of fistulizing disease and requires a multidisciplinary clinical and radiologic approach to differentiate surgical complications from recurrent Crohn's disease.

Abstract
Intestinal commensal bacteria contribute to maintaining gut homeostasis. Disruptions to the commensal flora are linked to the development and persistence of disease. The importance of these organisms is further demonstrated by the widespread ability of enteric viruses to exploit commensal bacteria to enhance viral infection. These viruses interact directly with commensal bacteria, and while the impact of this interaction on viral infection is well described for several viruses, the impact on the commensal bacteria has yet to be explored. In this article, we demonstrate, for the first time, that enteric viruses alter the gene expression and phenotype of individual commensal bacteria. Human and murine norovirus interaction with bacteria resulted in genome-wide differential gene expression and marked changes in the surface architecture of the bacterial cells. Furthermore, the interaction of the virus with bacteria led to increased production of smaller outer membrane vesicles (OMVs). Enhanced production of smaller vesicles was also observed when noroviruses were incubated with other commensal bacteria, indicating a potentially broad impact of norovirus interaction. The vesicle production observed in the in vivo model followed a similar trend where an increased quantity of smaller bacterial vesicles was observed in stool collected from virus-infected mice compared to mock-infected mice. Furthermore, changes in vesicle size were linked to changes in protein content and abundance, indicating that viral binding induced a shift in the mechanism of the OMV biogenesis. Collectively, these data demonstrate that enteric viruses induce specific changes in bacterial gene expression, leading to changes in bacterial extracellular vesicle production that can potentially impact host responses to infection.

Abstract
BACKGROUND The gastrointestinal microbiota is the key antigenic drive in the inflammatory bowel diseases. Randomized controlled trials (RCTs) in ulcerative colitis have established fecal microbiota transplantation (FMT) as an effective therapy. We have conducted a systematic review to evaluate the efficacy of FMT in Crohn's disease. METHODS A systematic literature search was performed through to August 2020 (MEDLINE; Embase). Studies were included if they reported FMT administration in patients with Crohn's disease, and reported on clinical outcomes. RESULTS Fifteen studies published between 2014 and 2020, comprising 13 cohort studies and two RCTs, were included in the analysis. The majority of trials evaluated FMT for induction of remission, with follow-up duration varying from 4 to 52 weeks. One RCT in 21 patients, of single-dose FMT versus placebo, following steroid-induced remission, showed a higher rate of steroid-free clinical remission in the FMT group compared to the control group: 87.5% vs 44.4% at week 10 (P = 0.23). Another RCT, two-dose FMT in 31 patients, showed an overall clinical remission rate of 36% at week 8, however, with no difference in clinical or endoscopic endpoints between FMT administered by gastroscopy and colonoscopy. Considering all studies, the clinical response rates in early follow up were higher following multiple FMT than with single FMT. FMT dose did not appear to influence clinical outcomes, nor did whether FMT was fresh or frozen. FMT delivered via upper gastrointestinal route demonstrated higher early efficacy rates of 75 to 100% compared with lower delivery route rates of 30% to 58%, but on follow up beyond 8 weeks, this difference was not maintained. Whether pre-FMT antibiotic administration was beneficial was not able to be determined due to the limited number of patients receiving antibiotics and varying antibiotic regimens. No serious adverse events were reported. CONCLUSIONS Preliminary studies suggest that FMT may be an effective therapy in Crohn's disease. However large controlled trials are needed. No serious safety concerns have been identified.

Abstract
Adherent-invasive Escherichia coli (AIEC) are pathogenic bacteria frequently isolated from patients who have Crohn's disease (CD). Despite the phenotypic differences between AIEC and commensal E. coli, comparative genomic approaches have been unable to differentiate these two groups, making the identification of key virulence factors a challenge. Here, we conduct a high-resolution, in vivo genetic screen to map AIEC genes required for intestinal colonization of mice. In addition, we use in vivo RNA-sequencing to define the host-associated AIEC transcriptome. We identify diverse metabolic pathways required for efficient gut colonization by AIEC and show that a type IV secretion system (T4SS) is required to form biofilms on the surface of epithelial cells, thereby promoting AIEC persistence in the gut. E. coli isolated from CD patients are enriched for a T4SS, suggesting a possible connection to disease activity. Our findings establish the T4SS as a principal AIEC colonization factor and highlight the use of genome-wide screens in decoding the infection biology of CD-associated bacteria that otherwise lack a defined genetic signature.

Abstract
BACKGROUND AND AIMS Perianal Crohn's disease [CD] places a considerable burden on patients' quality of life and is complex to treat. Despite its impact and high frequency, few studies have investigated the incidence and disease course of perianal CD. The aim of this study was to assess the incidence and disease course of perianal CD in adult patients throughout a 19-year period. METHODS The cohort comprised all individuals aged 18 years or older who were diagnosed with CD in Denmark between January 1, 1997, and December 31, 2015, according to the National Patient Registry [NPR]. RESULTS A total of 1812 [19%] out of 9739 patients with CD were found to have perianal CD. Perianal fistulas were the most common manifestation, accounting for 943 [52%] cases. The incidence of perianal CD remained stable over time. Patients with perianal CD were found to have an increased risk of undergoing major abdominal surgery compared with patients without perianal CD (hazard ratio: 1.51, 95% confidence interval [CI]: 1.40 to 1.64, p <0.001) in a multivariate Cox regression analysis. The incidence rate ratios of anal and rectal cancer in perianal CD patients were 11.45 [95% CI: 4.70 to 27.91, p <0.001] and 2.29 [95% CI: 1.25 to 4.20, p = 0.006], respectively, as compared with non-IBD matched controls. CONCLUSIONS In this nationwide study, 19% of CD patients developed perianal disease. Patients with perianal CD were at increased risk of undergoing major surgery compared with non-perianal CD patients. The risk of anal and rectal cancer was increased in patients with perianal CD compared with non-IBD matched controls.

Abstract
Diverse microbial signatures within the intestinal microbiota have been associated with intestinal and systemic inflammatory diseases, but whether these candidate microbes actively modulate host phenotypes or passively expand within the altered microbial ecosystem is frequently not known. Here we demonstrate that colonization of mice with a member of the genus Prevotella, which has been previously associated to colitis in mice, exacerbates intestinal inflammation. Our analysis revealed that Prevotella intestinalis alters composition and function of the ecosystem resulting in a reduction of short-chain fatty acids, specifically acetate, and consequently a decrease in intestinal IL-18 levels during steady state. Supplementation of IL-18 to Prevotella-colonized mice was sufficient to reduce intestinal inflammation. Hence, we conclude that intestinal Prevotella colonization results in metabolic changes in the microbiota, which reduce IL-18 production and consequently exacerbate intestinal inflammation, and potential systemic autoimmunity.

Abstract
AIMS This study's objectives were to examine and compare the cost-effectiveness of biologic and non-biologic therapies in the improvement of the health-related quality of life (HRQoL) of patients with inflammatory bowel disease (IBD) in Saudi Arabia. MATERIALS AND METHODS This retrospective cohort study analyzed data from the medical records of patients with IBD treated at a tertiary-care hospital in Riyadh, Saudi Arabia. Drug utilization costs and HRQoL scores were evaluated at baseline and after six months of treatment. Patients' HRQoL was measured using the Arabic version of the standardized EuroQol 5 Dimensional 3 Level (EQ-5D-3L) questionnaire with a visual analog scale (VAS). RESULTS Eighty-seven patients with Crohn's disease (CD) and 69 patients with ulcerative colitis (UC) were included in the study (N = 156), and 59 (37.82%) were treated with biologics. Similar effects of both types of medications were found on the HRQoL domains of mobility, usual activities, and pain and discomfort, while biologics outperformed non-biologics on the self-care domain. The mean utilization cost of a biologic-based treatment over a six-month period was SAR 25,690.46 (USD 6,850.79) higher than that of the non-biologic treatment (95% confidence interval (CI): 24,548.55-27,465.11), and the change in the ED-5D-3L VAS score from baseline to follow-up was 4.78 points (95% CI: 1.96-14.00). A probabilistic sensitivity analysis demonstrated that IBD therapy with biologic-based treatment is always more expensive, but also more effective in improving HRQoL 99.45% of the time. Adalimumab was found to be less cost effective than infliximab in the management of CD. LIMITATIONS Information bias cannot be ruled out, as this investigation was a retrospective cohort study with a relatively small sample that was not randomized. CONCLUSIONS The results of this analysis can serve as a foundation to introduce HRQoL-based recommendations for the use of biologics in the management of IBD in Saudi Arabia.

Abstract
Inflammatory bowel diseases (IBD), that includes ulcerative colitis and Crohn's disease, can affect not only the gastrointestinal tract but a wide spectrum of organs. The extra-intestinal manifestations (EIMs) are one of the most challenging aspect of IBD, playing a significant role for the lifetime care and the quality of life of patients. Ocular manifestations are the third most frequent EIMs, preceded by articular and dermatological ones. The aim of this narrative review is to describe the different types of ocular involvements, focusing on their clinical management. Uveitis and episcleritis are the most common ocular EIMs, differing for many aspects. Uveitis are unrelated with IBD activity and they even precede the onset of the intestinal disease, while episcleritis are common defined as a good mark of IBD activity. Pain is uncommon in most cases of episcleritis, while severe eye pain and photophobia are the most frequent onset of anterior uveitis. Less common but even more severe, are orbital pseudotumor or posterior segment involvement. Most of the ocular EIMs can be successfully treated with topic and oral steroids and the underlying therapy for IBD can reduce or cut out at all the recurrence of these manifestations. Symptoms are commonly not specific, in some cases being unnoticed for years leading to permanent ocular consequences. Cooperation between different specialists is crucial to avoid all the possible consequences of a non-treated EIMs, especially for ocular ones.

Abstract
Chronic obstructive pulmonary disease (COPD) has been considered a significant health challenge globally in recent years, which affects different aspects of the quality-of-life (QoL). A review was conducted of research output, research topics, and landscape to have a global view of the papers mentioning the interventions to increase QoL of patients with COPD. A total of 3242 research items from Web of Science during the period 1990-2018 were downloaded and analyzed. Analyses based on the different levels of data and methods using using VOSviewer software tool (version 1.16.15, Centre for Science and Technology Studies (CWTS), Leiden University, Leiden, The Netherlands) and Latent Dirichlet allocation. By exploring the trends in research productivity and topics, an increase was found in the number of papers mentioning non-pharmacological interventions as well as mental health illness and QoL among patients with COPD. In conclusion, the research on the interventions to increase the QoL of patients with COPD has attracted scientists globally. It is suggested that more research should be conducted on the effectiveness of non-pharmacological therapies to increase QoL of patients with COPD that can be applied broadly in the community. The collaboration and support from developed countries to developing countries are needed to increase the QoL of people living with COPD.

Strictureplasty versus bowel resection for the surgical management of fibrostenotic Crohn's disease: a systematic review and meta-analysis. Int J Colorectal Dis 2020; 35:705-717. [PMID: 32048011 DOI: 10.1007/s00384-020-03507-z] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Accepted: 01/08/2020] [Indexed: 02/07/2023]
Abstract
BACKGROUND Strictureplasty (SPX) conserves bowel length and minimizes the risk of developing short bowel syndrome in patients undergoing surgery for Crohn's disease (CD). However, SPX may be associated with a higher risk of recurrence compared with bowel resection (BR). AIM We sought to compare morbidity and recurrence following SPX and BR in patients with fibrostenotic CD. METHODS A systematic review was performed according to PRISMA and MOOSE guidelines. Observational studies that compared outcomes of CD patients undergoing either SPX or BR were identified. Log hazard ratios (InHR) for recurrence-free survival (RFS) and their standard errors were calculated from Kaplan-Meier plots or Cox regression models and pooled using the inverse variance method. Dichotomous variables were pooled as odds ratios (OR) using the Mantel-Haenszel method. Continuous variables were pooled as weighted mean differences. RESULTS Twelve studies of 1026 CD patients (SPX n = 444, 43.27%; BR with or without SPX n = 582, 56.72%) were eligible for inclusion. There was an increased likelihood of disease recurrence with SPX than with BR (OR 1.61; 95% CI, 1.03, 2.52; p = 0.04; I2 = 0%). Patients who had a SPX alone had a significantly reduced RFS than those who underwent BR (HR 1.47; 95% CI, 1.08, 2.01; p = 0.02; I2 = 0%). There was no difference in morbidity between the groups (OR 0.58; 95% CI, 0.26, 1.28; p = 0.18; I2 = 0%). CONCLUSION SPX should only be performed in those patients with Crohn's strictures that are at high risk for short bowel syndrome and intestinal failure; otherwise, BR is the favored surgical technique for the management of fibrostenotic CD.

Colonic microbiota is associated with inflammation and host epigenomic alterations in inflammatory bowel disease. Nat Commun 2020; 11:1512.

Abstract
Studies of inflammatory bowel disease (IBD) have been inconclusive in relating microbiota with distribution of inflammation. We report microbiota, host transcriptomics, epigenomics and genetics from matched inflamed and non-inflamed colonic mucosa [50 Crohn's disease (CD); 80 ulcerative colitis (UC); 31 controls]. Changes in community-wide and within-patient microbiota are linked with inflammation, but we find no evidence for a distinct microbial diagnostic signature, probably due to heterogeneous host-microbe interactions, and show only marginal microbiota associations with habitual diet. Epithelial DNA methylation improves disease classification and is associated with both inflammation and microbiota composition. Microbiota sub-groups are driven by dominant Enterbacteriaceae and Bacteroides species, representative strains of which are pro-inflammatory in vitro, are also associated with immune-related epigenetic markers. In conclusion, inflamed and non-inflamed colonic segments in both CD and UC differ in microbiota composition and epigenetic profiles.

Abstract
BACKGROUND Early bowel resection (EBR) in ileocolonic Crohn's disease (CD) may be associated with more durable remission compared with initial medical therapy (IMT) even when biologic therapy is included. AIM To compare the efficacy of EBR versus IMT for ileocolonic CD METHODS: A systematic search was performed to identify studies that compared EBR (performed < 1 year from initial diagnosis) or IMT for the management of ileocolonic CD. Log hazard ratios (InHR) for relapse-free survival (RFS) and their standard errors were calculated from Kaplan-Meier plots and pooled using the inverse-variance method. Dichotomous variables were pooled as odds ratios (OR). Quality assessment of the included studies was performed using the Newcastle-Ottawa (NOS) and Jadad scales. RESULTS A total of 7 studies with 1863 CD patients (EBR n = 581, 31.2%; IMT n = 1282, 68.8%) were eligible for inclusion. There was a moderate-to-high risk of bias. The median NOS was 8 (range 7-9). There was a reduced likelihood of overall (OR, 0.53; 95% confidence interval (95% CI), 0.34, 0.83; p = 0.005) and surgical (OR, 0.47; 95% CI, 0.24, 0.91; p = 0.03) relapse with EBR. There was also a less requirement for maintenance biologic therapy (OR, 0.24; 95% CI, 0.14, 0.42; p < 0.0001). Patients who underwent EBR had a significantly improved RFS than those who underwent IMT (HR, 0.62; 95% CI, 0.52, 0.73; p < 0.001). There was no difference in morbidity (OR, 1.67; 95% CI, 0.44, 6.36; p = 0.45) between the groups. CONCLUSION EBR may be associated with less relapse and need for maintenance biologic therapy than IMT. 'Upfront' or early resection may represent a reasonable and cost-effective alternative to biologic therapy, especially in biologic-resistant subpopulations.

Abstract
The aetiology of inflammatory bowel diseases (IBD) seems to be strongly connected to changes in the enteral microbiome. The dysbiosis pattern seen in Crohn’s disease (CD) differs among published studies depending on patients’ age, disease phenotype and microbiome research methods. The aims was to investigate microbiome in treatment-naive paediatric patients to get an insight into its structure at the early stage of the disease in comparison to healthy. Stool samples were obtained from controls and newly diagnosed patients prior to any intervention. Microbiota was analysed by 16SrRNAnext-generation-sequencing (NGS). Differences in the within-sample phylotype richness and evenness (alpha diversity) were detected between controls and patients. Statistically significant dissimilarities between samples were present for all used metrics. We also found a significant increase in the abundance of OTUs of the Enterococcus genus and reduction in, among others, Bifidobacterium (B. adolescentis), Roseburia (R.faecis), Faecalibacterium (F. prausnitzii), Gemmiger (G. formicilis), Ruminococcus (R. bromii) and Veillonellaceae (Dialister). Moreover, differences in alpha and beta diversities in respect to calprotectin and PCDAI were observed: patients with calprotectin <100 µg/g and with PCDAI below 10 points vs those with calprotectin >100 µg/g and mild (10–27.7 points), moderate (27.5–40 points) or severe (>40 points) CD disease activity had higher richness and diversity of gut microbiota. The results of our study highlight reduced diversity and dysbiosis at the earliest stage of the disease. Microbial imbalance and low abundance of butyrate-producing bacteria, including Bifidobacterium adolescentis, may suggest benefits of microbial modification therapy.

Abstract
Case report: We present a case of a 66-year-old female diagnosed with R. gnavus bacteremia associated with fecal peritonits secondary to small-bowel herniation and perforation. Identification as R. gnavus was delayed because of absence of this species in the MALDI-TOF MS database (Vitek MS, bioMérieux). Identification was provided by 16S rRNA gene sequencing. Review: R. gnavus, a Gram-positive, strictly anaerobic bacterium, is a member of the human gut microbiota. Dysbiosis in the gut microbiota, with increased amounts of R. gnavus, has been described in inflammatory bowel disease. R. gnavus has only been reported occasionally as the cause of infections. Hence the potential pathogenicity is not yet fully recognized, and data regarding the antimicrobial susceptibility profile are rare. Identification of anaerobic bacteria such as R. gnavus is greatly accelerated as a result of the introduction of MALDI-TOF MS. However, as illustrated in this case report, an extensive and up-to-date MALDI-TOF MS database is necessary for providing an accurate identification.

Abstract
Biological intervention for Crohn's Disease (CDs) patients, mainly using anti-TNF antibodies, is often an efficient therapeutic solution. Nonetheless, data defining the administration timing to maximize the chances of clinical remission are lacking. The objective of this “real-life” retrospective study was to evaluate if early Adalimumab (ADA) administration (<12 months) was an efficient strategy to improve patients' clinical outcome. This single center study included 157 CD patients, of which 80 received the first ADA administration within the first 12 months from the diagnosis. After 1 year of therapy, clinical remission was observed in 50.32% of patients, mucosal healing in 37.58%. Clinical remission was observed in 66.25% of the early ADA administration patients vs. 33.77% of the late (>12 months) (p < 0.001); mucosal healing was observed in 53.75% of the early vs. 20.78% of the late (p < 0.001). Dose escalation was required for 30.00% of the early vs. 66.23% of the late (<0.01). In the early ADA administration group, 7.50% patients were considered non-responders at the end of the follow-up vs. 22.08% patients in the late administration group. These findings highlighted that early ADA administration (within 1 year of diagnosis) improves the clinical response and mucosal healing, and reduces the loss of response rate and need for dose escalation.

Abstract
INTRODUCTION Several grading schemes are available to assess surgical complications, but their relationship with patient-reported outcomes is not well understood. Therefore, our objective was to examine the effect of two complication grading schemas on health-related quality of life in colorectal surgery patients. METHODS An analysis of adult patients undergoing elective colorectal surgery from 2005 to 2013 was performed. Health-related quality of life was measured using the SF-36 preoperatively and at 4 weeks and 8 weeks postoperatively. The 30-day morbidity was classified using Clavien-Dindo grading (I-IV) and the Comprehensive Complication Index (0-100). The main outcomes were the postoperative changes in physical summary scores and mental summary scores. Multivariate logistic and fractional polynomial regression analyses were used to determine the relationship between complication severity and health-related quality of life. RESULTS A total of 402 patients were included in the study. Overall morbidity was 46%. Patients with complications had lower physical summary scores and mental summary scores at 4-weeks and 8-weeks postoperatively compared with patients without complications (P < .05). On multivariate regression, there was no dose-response relationship between Clavien-Dindo grade and postoperative physical summary scores and mental summary scores. Adjusted changes in the physical summary scores and mental summary scores had a more appropriate, dose-response relationship with the Comprehensive Complication Index scores. CONCLUSION In patients undergoing colorectal surgery, there is a more consistent relationship between the Comprehensive Complication Index and postoperative health-related quality of life compared with the Clavien-Dindo classification.

Abstract
Background We aim to discover whether HbA1c affects incident cardiovascular disease (CVD) through regulating endogenous metabolites. Methods and Results Totally, 2019 plasma samples were analyzed by liquid chromatography‐quadrupole time‐of‐flight mass spectrometry. Logistic regression and linear regression were used to screen metabolites which were associated with both CVD and HbA1c. The VanderWeele's mediation approach was performed to assess the direct effect and indirect effect (IE) in the counterfactual model. Forty‐eight metabolites showed an association with both HbA1c and CVD risk. Forty‐four of the 48 metabolites worked as mediators mediated in HbA1c's effect on CVD (odds ratio [OR]IE from 0.997 to 6.098, false discovery rate q < 0.05, mediated proportion from 0.4% to 85.4%). Pathway enrichment analysis indicated that different metabolic pathway showed significant IE (butanoate metabolism ORIE = 1.058, mediated proportion = 16.0%; alanine, aspartate and glutamate metabolism ORIE = 1.082, mediated proportion = 21.8%; TCA (citric acid) cycle metabolism ORIE = 1.048, mediated proportion = 13.8%; phenylalanine metabolism ORIE = 1.067, mediated proportion = 18.4%; glycerophospholipid metabolism ORIE = 3.007, mediated proportion = 82.2%; all the P < .01). Conclusions Our findings suggest that metabolites mediate the effect of HbA1c on incident CVD and provide a new study sight into pathogenesis of CVD.

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
Crohn's disease (CD) is a chronic inflammatory condition of the gastrointestinal tract resulting in progressive tissue damage, which can result in strictures, fistulae, and abscesses formation. The triggering mechanism is thought to be in the fecal stream, and diversion of this fecal stream is sometimes required to control disease when all other avenues of medical and surgical management have been exhausted. Fecal diversion can be temporary or permanent with the indications being defunctioning a high-risk anastomosis, as a result of a surgical complication, for disease control, or due to severe colonic, rectal, or perianal disease. The incidence of ostomy formation in CD has increased epidemiologically over time. The primary indication for ostomy formation is severe perianal fistulizing disease. However, while 64% of patients have an early clinical response after diversion for refractory perianal CD, restoration of bowel continuity is attempted in only 35% of patients, and is successful in only 17%. The current review discusses the indications for ostomy creation in complex CD, strategies for procedure selection, and patient outcomes.

Abstract
BACKGROUND Crohn disease (CD) is associated with substantial healthcare related costs and impairment of quality of life. Tripterygium wilfordii Hook F (TwHF) is proved to be effective for CD in animal and human. However, there is no systemic review and meta-analysis regarding the clinical efficacy and safety of TwHF preparation for the treatment of CD. METHODS Six electronic databases (Medline, EMBASE, Cochrane database, Chinese National Knowledge Infrastructure, Wanfang Database and Chongqing VIP Database) will be searched for eligibility studies. Data from the included studies will be extracted and the quality of studies will be assessed. Data synthesis will be performed using Review Manager software. Sensitivity analysis and publication bias assessment will also be carried out. RESULTS This systemic review and meta-analysis will provide synthesized result of clinical efficacy and safety of TwHF preparation for the treatment of CD. CONCLUSION This research will determine the clinical efficacy and safety of TwHF preparation for the treatment of CD.Registration: PROSPERO CRD42019127893.

Abstract
BACKGROUND Crohn's disease (CD) treatments and associated adverse events (AEs) can be burdensome for patients. However, specific values which quantify the impact on health-related quality of life (HRQL) for economic evaluation are lacking. OBJECTIVES This study aimed to elicit health utility values for AEs related to biologic treatment and surgical complications for CD in the UK. METHODS Health states were developed by literature review and interviews with CD patients (n=6) and gastroenterologists (n=3). Draft health states were validated in cognitive debrief interviews with patients (n=4) and gastroenterologists (n=2). Treatment AEs were described with moderate-severe CD (reference state) and included hypersensitivity, injection site reactions, serious infection, lymphoma, and tuberculosis. Surgical complications were described following bowel surgery (reference state) and included anastomotic leak, wound infection, prolonged ileus/bowel obstruction, and intra-abdominal abscess. Health states were valued by 100 members of the general public who completed background questions, EQ-5D-3L, visual analogue scale rating task and time trade-off (TTO) interviews. RESULTS The mean TTO value for reference states 'moderate to severe CD' and 'bowel surgery' were 0.70 (SD=0.28) and 0.69 (SD=0.28). Participants rated lymphoma as the worst AE/surgical complication state (0.44, SD=0.37), followed by tuberculosis (0.47, SD=0.85) and anastomotic leak (0.48, SD=0.38). Values of other AE/surgical complication states ranged from 0.76 (hypersensitivity) to 0.56 (intra-abdominal abscess). CONCLUSIONS This study provides utility estimates for AE and surgical complication health states not previously assessed in the context of CD. As new treatments are emerging, it is important to include these influences on quality of life in any economic evaluation of treatments.

Abstract
Proteomics is a widely used method for defining the protein composition of a complex sample. As this approach allows for identification and quantification of proteins across a broad dynamic range as well as detection of post-translational modifications, proteomics is an ideal platform to investigate the gut microbiome at a functional level. The gut microbiome is a dynamic environment which is crucial for overall health and fitness. Imbalances in the gut microbiome can influence nutrient absorption, pathogen resistance, inflammation, and various human diseases. Metaproteomic analysis of the gut microbiome is currently being performed on bacteria isolated from (1) fecal samples (2) colonic lavage, or (3) colon biopsies. Investigation of the gut microbiome has demonstrated that within the colon, there are distinct communities based on spatial location, and separable from the gut microbiomes isolated from stool. In addition to expanding our understanding of host-bacterial interactions for human health and disease, gut microbiome analysis is being utilized for biomarker development to discriminate normal individuals and diseased (i.e., inflammatory bowel disease or colon cancer) patients as well as to monitor disease activity and prognosis.

Abstract
Perianal localization of Crohn's disease involves significant morbidity, affects quality of life and results in an increased use of healthcare resources. Medical and surgical therapies contribute to its management. The objective of this review is to address the current understanding in the management of perianal Crohn's disease, with the main focus in reviewing pharmacological therapies, including stem cells. In complex fistulas, once local sepsis has been controlled by surgical drainage and/or antibiotics, anti-TNF drugs (infliximab, adalimumab) are the first-line therapy, with or without associated immunomodulators. Combining surgery and anti-TNF therapy has additional benefits for healing. However, response is inadequate in up to half of cases. A possible role of new biological drugs in this context (vedolizumab, ustekinumab) is an area of ongoing investigation, as is the local application of autologous or allogeneic mesenchymal stem cells. These are non-hematopoietic multipotent cells with anti-inflammatory and immunomodulatory properties, the use of which may successfully treat refractory patients, and seem to be a promising and safe alternative to achieving fistula healing in Crohn's disease, without known systemic effects.

Abstract
Inflammatory bowel disease (IBD) has a substantial impact on quality of life. It causes considerable personal, emotional and social burdens. The impact of IBD on quality of life cannot readily be quantified as a cost; however, the impact places a significant burden on the patient and caregivers. Numerous studies have shown that health-related quality of life is impaired in patients living with IBD as compared with the general population. While disease activity and severity is an important driver of physical and mental health–related quality of life, patients may experience psychological distress even during clinical remission. Reduced quality of life can impact persons living with IBD as they pursue employment, family planning and personal milestones. Further, the impact of IBD extends to the patient influencing the quality of lives of those around them, including their caregivers. Improving quality of life requires a multidisciplinary approach that includes screening for and managing psychological distress. Adaptive coping mechanisms help manage illness perceptions and reduce psychosocial distress. Highlights Key Summary Points Gaps in Knowledge and Future Directions

Tuning of human MAIT cell activation by commensal bacteria species and MR1-dependent T-cell presentation. Mucosal Immunol 2018; 11:1591-1605.

Abstract
Human mucosal-associated invariant T (MAIT) cell receptors (TCRs) recognize bacterial riboflavin pathway metabolites through the MHC class 1-related molecule MR1. However, it is unclear whether MAIT cells discriminate between many species of the human microbiota. To address this, we developed an in vitro functional assay through human T cells engineered for MAIT-TCRs (eMAIT-TCRs) stimulated by MR1-expressing antigen-presenting cells (APCs). We then screened 47 microbiota-associated bacterial species from different phyla for their eMAIT-TCR stimulatory capacities. Only bacterial species that encoded the riboflavin pathway were stimulatory for MAIT-TCRs. Most species that were high stimulators belonged to Bacteroidetes and Proteobacteria phyla, whereas low/non-stimulator species were primarily Actinobacteria or Firmicutes. Activation of MAIT cells by high- vs low-stimulating bacteria also correlated with the level of riboflavin they secreted or after bacterial infection of macrophages. Remarkably, we found that human T-cell subsets can also present riboflavin metabolites to MAIT cells in a MR1-restricted fashion. This T-T cell-mediated signaling also induced IFNγ, TNF and granzyme B from MAIT cells, albeit at lower level than professional APC. These findings suggest that MAIT cells can discriminate and categorize complex human microbiota through computation of TCR signals depending on antigen load and presenting cells, and fine-tune their functional responses.

Abstract
Studies of the human intestinal microbiome in patients with inflammatory bowel disease (IBD) consistently show that there are differences (an abnormal or unbalanced microbiome, "dysbiosis") when compared to healthy subjects. We sought to describe changes in the microbiome in individual patients over time, and determine the clinical factors that are associated with significant alteration. Forty-two mucosal biopsies were collected from 20 patients that were spaced an average of 2.4 years apart. These were analysed using bacterial 16S rRNA gene high-throughput sequencing methods. Presence of active inflammation was determined endoscopically and histologically. Inferred metagenomics analysis was conducted using the PICRUSt package. We found that the differences in the microbiome over time in individual patients were greatest in the presence of ongoing intestinal inflammation, as determined by the Yue and Clayton theta distance between sample pairs (adjusted p = 0.00031). Samples from patients with previous abdominal surgery had lower alpha (within sample) diversity compared with those with no prior operations (mean Shannon index 2.083, 2.510 respectively, p = 0.017). There were no changes in the inferred bacterial metagenomic profile. The microbiome in IBD undergoes considerable fluctuation over time. These changes are greatest when there is histologically confirmed inflammation at both time-points.

Abstract
OBJECTIVES Exclusive enteral nutrition (EEN) is an effective induction treatment for pediatric Crohn disease. Given the center-based variation in use and diversity in practice, we constructed a survey aimed at sharing experience and strategies in administering EEN, stimulating further research, and optimizing therapy. METHODS This survey was constructed after consultation with experts and designed to address key knowledge gaps. The survey was disseminated through the Pediatric IBD Porto Group of ESPGHAN, Canadian Children IBD Network, selective experts, and was sent twice through the Pediatric Gastrointestinal-Bulletin Board (PEDGI-BB). Data were collected into REDCap and analyzed using descriptive statistics. RESULTS In total, 146 participants from 26 countries completed the survey. Sixty-five percentage of participants were general, non-inflammatory bowel diseases (IBD)-focused pediatric gastroenterologists, 21% were IBD-focused, and 10% were dietitians. The most common indications (∼90% use) were for ileocecal and ileocolonic disease (Paris L1 and L3). The most common duration was 8 weeks and 66% preferred oral to nasogastric administration. Most (63%) did not allow any additional intake and 69% instructed patients to continue partial enteral nutrition (EN) after completing treatment. Dietitians were identified as essential to EEN success while the primary challenges of EEN programs were adherence and lack of support. Regional and professional practice differences were observed in EEN indication, age, exclusivity, program structure/support, and cost coverage. CONCLUSIONS We found significant variation in practice and use of EEN with several regional and professional differences. Global variation offers opportunities for research and improving care. This survey establishes a framework and provides resources for collaboration and information sharing.

Abstract
BACKGROUND Inflammatory bowel disease (IBD) is associated with poor quality of life and disability. The short inflammatory bowel disease questionnaire (SIBDQ) is validated to determine patients quality of life at single time points, or improvement over time. Few studies have evaluated if sustained poor quality of life is associated with future healthcare utilization patterns. METHODS We analyzed patients from a prospective IBD natural history registry with 4 consecutive years of follow-up. SIBDQ was measured at outpatient visits. Healthcare utilization data were temporally organized into a 2-year observation period, and 2-year follow-up period. Mean SIBDQ score <50 during the first 2 years was categorized as having "poor quality of life". Primary outcomes of interest were measures of unplanned healthcare utilization and opioid use. RESULTS From a total of 447 participants (56.1% female, 66.1% Crohn's disease, 34.9% ulcerative colitis), 215 (48.1%) were classified as having poor quality of life. Poor quality of life was significantly associated with Crohn's disease (P < 0.01), history of IBD related surgery, and tobacco use (all P < 0.01). In the follow-up period, the same patients with poor quality of life were more likely to have abnormal biomarkers of inflammation, more telephone calls and office visits, experience unplanned care, and be exposed to opiates (all P < 0.05). After multivariable analysis, poor quality of life remained an independent predictor of future opiate use (odds ratio: 2.2, P = 0.003) and decreased time to first opiate prescription (hazard ratio: 1.67, P = 0.019) in the follow-up period. CONCLUSIONS IBD patients with sustained poor quality of life are at an increased risk of opiate use and decreased time to opiate exposure. Routine measurement of quality of life in the outpatient setting may provide insight into those at risk for narcotic use and healthcare utilization. 10.1093/ibd/izy040_video1izy040.video25791709872001.

Abstract
The introduction of vedolizumab, a lymphocyte adhesion inhibitor, has expanded the relatively limited therapeutic armamentarium available for Crohn's disease and ulcerative colitis. Despite its effectiveness, both primary nonresponse and secondary loss of response to vedolizumab do occur, as is observed with the use of anti-tumour necrosis factor (TNF) therapy. Further, in a proportion, onset of efficacy may be relatively slow. A large body of data support an exposure-response relationship with anti-TNF drug levels, which has led to therapeutic drug monitoring becoming incorporated into everyday clinical management. The influence of patient and disease factors on the pharmacokinetics of anti-TNF levels, including immunogenicity, has also been examined. The role of therapeutic drug monitoring with vedolizumab is less clear. This review summarizes the available evidence on the pharmacokinetics and pharmacodynamics of vedolizumab in inflammatory bowel disease and how drug levels, immunogenicity and other factors influence clinical outcomes. Vedolizumab clearance is increased with very high body weight and hypoalbuminaemia, but is not influenced by the addition of an immunomodulator. Immunogenicity is uncommon. α4β7 receptor saturation occurs at low serum vedolizumab drug levels, and measuring it alone is insufficient to predict clinical outcomes. Using quartile analysis of vedolizumab drug levels, there appears to be a modest exposure-response relationship during induction. Drug levels at week 6 of approximately >20 μg/ml have been shown to be associated with improved clinical outcomes, including subsequent mucosal healing rates during maintenance and avoiding the need to dose escalate due to lack of response. There are currently insufficient data to support the routine use of therapeutic drug monitoring during maintenance therapy. Further studies to elucidate the role of therapeutic drug monitoring of vedolizumab are needed.

Abstract
Inflammatory bowel disease (IBD) is an umbrella term for Crohn's disease (CD) and ulcerative colitis (UC). In light of evolving epidemiology of CD, its clinical management is still complex and remains a challenge for contemporary physicians. With the advent of new diagnostic and treatment paradigms, there is a growing need for new biomarkers to guide decision-making, differential diagnosis, disease activity monitoring, as well as prognosis. However, both clinical and endoscopic scoring systems, widely utilized for disease monitoring and prognosis, have drawbacks and limitations. In recent years, biochemical peptides have become available for IBD monitoring and more frequently used as surrogate markers of gut inflammation. Emerging concepts that revolve around molecular, stem cell, epigenetic, microbial or metabolomic pathways associated with vascular and epithelial gut barrier could lead to development of new CD biomarkers. Measurement of cell-derived microvesicles (MVs) in the blood of IBD patients is another emerging concept helpful in future disease management. In this review, we discuss novel concepts of non-invasive biomarkers, which may become useful in monitoring of CD activity and prognosis. We discuss metabolomics as a new powerful tool for clinicians to guide differential IBD diagnosis. In the coming years, new developments of prognostic tools are expected, aiming for breakthroughs in the management of patients with CD.

Abstract
BACKGROUND The Inflammatory Bowel Disease Disability Index (IBD-DI) has recently been developed for patients with Crohn's disease (CD) and ulcerative colitis (UC). AIM To assess the severity of disability and associated factors using the IBD-DI, and review the validity of the IBD-DI as a tool. METHOD Systematic review of cross-sectional studies. Patients included had UC or CD and were classified as active, in remission, or needing surgery, biological and/or steroid treatment. We included studies assessing disability using the IBD-DI and that were captured by electronic and manual searches (January 2017). The possibility of bias was evaluated with the Newcastle-Ottawa Scale. RESULTS Nine studies were included with 3167 patients. Comparatively, patients with active disease had higher disability rates than those in remission (SMD [CI95] = 1.49[1.11, 1.88], I2 = 94%, P<.01), while patients on biological treatment had lower disability rates than those receiving corticosteroid treatment (SMD [CI95] = -0.22[-0.36, -0.08], I2 = 0%, P<.01). Disease activity and unemployment were found to be associated factors. The IBD-DI scored "good" for internal consistency, "fair" to "excellent" for intra-rater reliability and "excellent" for inter-rater reliability. Construct validity was "moderately strong" to "very strong" and structural validity was found to be mainly unidimensional. The IBD-DI had excellent responsiveness, while its interpretability was only useful on a group level. CONCLUSIONS This systematic review and meta-analysis found a significant association between disease activity, treatment received and disability; although significant heterogeneity was found. The IBD-DI is reliable and valid, but further studies are needed to measure its interpretability.

BMC Bioinformatics 2017; 18:441. [PMID: 28978318 PMCID: PMC5628491 DOI: 10.1186/s12859-017-1843-1] [Citation(s) in RCA: 15] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/14/2016] [Accepted: 09/21/2017] [Indexed: 02/08/2023] Open
Abstract
BACKGROUND The human microbiota is associated with various disease states and holds a great promise for non-invasive diagnostics. However, microbiota data is challenging for traditional diagnostic approaches: It is high-dimensional, sparse and comprises of high inter-personal variation. State of the art machine learning tools are therefore needed to achieve this goal. While these tools have the ability to learn from complex data and interpret patterns therein that cannot be identified by humans, they often operate as black boxes, offering no insight into their decision-making process. In most cases, it is difficult to represent the learning of a classifier in a comprehensible way, which makes them prone to be mistrusted, or even misused, in a clinical environment. In this study, we aim to elucidate microbiota-based classifier decisions in a biologically meaningful context to allow their interpretation. RESULTS We applied a method for explanation of classifier decisions on two microbiota datasets of increasing complexity: gut versus skin microbiota samples, and inflammatory bowel disease versus healthy gut microbiota samples. The algorithm simulates bacterial species as being unknown to a pre-trained classifier, and measures its effect on the outcome. Consequently, each patient is assigned a unique quantitative estimation of which species in their microbiota defined the classification of their sample. The algorithm was able to explain the classifier decisions well, demonstrated by our validation method, and the explanations were biologically consistent with recent microbiota findings. CONCLUSIONS Application of a method for explaining individual classifier decisions for complex microbiota analysis proved feasible and opens perspectives on personalized therapy. Providing an explanation to support a microbiota-based diagnosis could guide decisions of clinical microbiologists, and has the potential to increase their confidence in the outcome of such decision support systems. This may facilitate the development of new diagnostic applications.

Laparoscopic ileocaecal resection versus infliximab for terminal ileitis in Crohn's disease: a randomised controlled, open-label, multicentre trial. Lancet Gastroenterol Hepatol 2017; 2:785-792. [PMID: 28838644 DOI: 10.1016/s2468-1253(17)30248-0] [Citation(s) in RCA: 180] [Impact Index Per Article: 25.7] [Reference Citation Analysis] [Abstract] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/04/2017] [Revised: 07/09/2017] [Accepted: 07/24/2017] [Indexed: 02/06/2023]
Abstract
BACKGROUND Treatment of patients with ileocaecal Crohn's disease who have not responded to conventional therapy is commonly scaled up to biological agents, but surgery can also offer excellent short-term and long-term results. We compared laparoscopic ileocaecal resection with infliximab to assess how they affect health-related quality of life. METHODS In this randomised controlled, open-label trial, in 29 teaching hospitals and tertiary care centres in the Netherlands and the UK, adults with non-stricturing, ileocaecal Crohn's disease, in whom conventional therapy has failed were randomly allocated (1:1) by an internet randomisation module with biased-coin minimisation for participating centres and perianal fistula to receive laparoscopic ileocaecal resection or infliximab. Eligible patients were aged 18-80 years, had active Crohn's disease of the terminal ileum, and had not responded to at least 3 months of conventional therapy with glucocorticosteroids, thiopurines, or methotrexate. Patients with diseased terminal ileum longer than 40 cm or abdominal abscesses were excluded. The primary outcome was quality of life on the Inflammatory Bowel Disease Questionnaire (IBDQ) at 12 months. Secondary outcomes were general quality of life, measured by the Short Form-36 (SF-36) health survey and its physical and mental component subscales, days unable to participate in social life, days on sick leave, morbidity (additional procedures and hospital admissions), and body image and cosmesis. Analyses of the primary outcome were done in the intention-to-treat population, and safety analyses were done in the per-protocol population. This trial is registered at the Dutch Trial Registry (NTR1150). FINDINGS Between May 2, 2008, and October 14, 2015, 73 patients were allocated to have resection and 70 to receive infliximab. Corrected for baseline differences, the mean IBDQ score at 12 months was 178·1 (95% CI 171·1-185·0) in the resection group versus 172·0 (164·3-179·6) in the infliximab group (mean difference 6·1 points, 95% CI -4·2 to 16·4; p=0·25). At 12 months, the mean SF-36 total score was 112·1 (95% CI 108·0-116·2) in the resection group versus 106·5 (102·1-110·9) in the infliximab group (mean difference 5·6, 95% CI -0·4 to 11·6), the mean physical component score was 47·7 (45·7-49·7) versus 44·6 (42·5-46·8; mean difference 3·1, 4·2 to 6·0), and the mean mental component score was 49·5 (47·0-52·1) versus 46·1 (43·3-48·9; mean difference 3·5, -0·3 to 7·3). Mean numbers of days of sick leave were 3·4 days (SD 7·1) in the resection group versus 1·4 days (4·7) in the infliximab group (p<0·0001), days not able to take part in social life were 1·8 days (6·3) versus 1·1 days (4·5; p=0·20), days of scheduled hospital admission were 6·5 days (3·8) versus 6·8 days (3·2; p=0·84), and the number of patients who had unscheduled hospital admissions were 13 (18%) of 73 versus 15 (21%) of 70 (p=0·68). Body-image scale mean scores in the patients who had resection were 16·0 (95% CI 15·2-16·8) at baseline versus 17·8 (17·1-18·4) at 12 months, and cosmetic scale mean scores were 17·6 (16·6-18·6) versus 18·6 (17·6-19·6). Surgical intervention-related complications classified as IIIa or worse on the Clavien-Dindo scale occurred in four patients in the resection group. Treatment-related serious adverse events occurred in two patients in the infliximab group. During a median follow-up of 4 years (IQR 2-6), 26 (37%) of 70 patients in the infliximab group had resection, and 19 (26%) of 73 patients in the resection group received anti-TNF. INTERPRETATION Laparoscopic resection in patients with limited (diseased terminal ileum <40 cm), non-stricturing, ileocaecal Crohn's disease in whom conventional therapy has failed could be considered a reasonable alternative to infliximab therapy.

Abstract
BACKGROUND Although there is some evidence suggesting that certain viruses may be involved in the onset of inflammatory bowel disease (IBD), data regarding viral prevalence and viral load in blood and mucosa of patients with IBD are scarce. The main aim of this study is to evaluate the prevalence and viral load of common Epstein-Barr virus (EBV), cytomegalovirus (CMV), and human herpes virus 6 in blood and mucosa of adult patients with endoscopic active IBD. METHODS From January to December 2014, ulcerative colitis and Crohn's disease patients with active endoscopic disease were consecutively enrolled. Subjects undergoing colonoscopy for colorectal cancer screening served as healthy controls (HCs). Paired blood and mucosal samples from each patient and HC were collected for EBV, CMV, and human herpes virus 6 quantitative real time polymerase chain reaction assessment of the viral load. RESULTS One hundred forty-five subjects were included; 95 IBD patients with active endoscopic disease (43 ulcerative colitis and 52 Crohn's disease) and 50 healthy subjects. CMV and EBV DNA were detected more frequently in the mucosa of patients with IBD compared with HCs (CMV P = 0.017; EBV P < 0.001), irrespective of IBD type. The frequency of human herpes virus 6 DNA detection both in the blood and in the mucosa did not differ between patients with IBD and HCs. EBV median viral load was similar in the inflamed and noninflamed mucosa was not affected by the use of immunomodulators and/or anti-tumor necrosis factor alpha agents, and did not correlate with endoscopic disease activity. CONCLUSIONS EBV, and to a lesser extent CMV, were more prevalent in patients with IBD than in HCs. Mucosal viral load was not influenced by the therapeutic regimen, did not differ between inflamed and noninflamed mucosa, and did not seem to be influenced by the endoscopic activity of the disease, suggesting that EBV may be more involved in the onset of IBD than in its severity and clinical evolution.

Genome-resolved metaproteomic characterization of preterm infant gut microbiota development reveals species-specific metabolic shifts and variabilities during early life. MICROBIOME 2017; 5:72.

Abstract
BACKGROUND Establishment of the human gut microbiota begins at birth. This early-life microbiota development can impact host physiology during infancy and even across an entire life span. However, the functional stability and population structure of the gut microbiota during initial colonization remain poorly understood. Metaproteomics is an emerging technology for the large-scale characterization of metabolic functions in complex microbial communities (gut microbiota). RESULTS We applied a metagenome-informed metaproteomic approach to study the temporal and inter-individual differences of metabolic functions during microbial colonization of preterm human infants' gut. By analyzing 30 individual fecal samples, we identified up to 12,568 protein groups for each of four infants, including both human and microbial proteins. With genome-resolved matched metagenomics, proteins were confidently identified at the species/strain level. The maximum percentage of the proteome detected for the abundant organisms was ~45%. A time-dependent increase in the relative abundance of microbial versus human proteins suggested increasing microbial colonization during the first few weeks of early life. We observed remarkable variations and temporal shifts in the relative protein abundances of each organism in these preterm gut communities. Given the dissimilarity of the communities, only 81 microbial EggNOG orthologous groups and 57 human proteins were observed across all samples. These conserved microbial proteins were involved in carbohydrate, energy, amino acid and nucleotide metabolism while conserved human proteins were related to immune response and mucosal maturation. We identified seven proteome clusters for the communities and showed infant gut proteome profiles were unstable across time and not individual-specific. Applying a gut-specific metabolic module (GMM) analysis, we found that gut communities varied primarily in the contribution of nutrient (carbohydrates, lipids, and amino acids) utilization and short-chain fatty acid production. CONCLUSIONS Overall, this study reports species-specific proteome profiles and metabolic functions of human gut microbiota during early colonization. In particular, our work contributes to reveal microbiota-associated shifts and variations in the metabolism of three major nutrient sources and short-chain fatty acid during colonization of preterm infant gut.

Abstract
Background A vast diversity of microbes colonizes in the human gastrointestinal tract, referred to intestinal microbiota. Microbiota and products thereof are indispensable for shaping the development and function of host innate immune system, thereby exerting multifaceted impacts in gut health. Methods This paper reviews the effects on immunity of gut microbe-derived nucleic acids, and gut microbial metabolites, as well as the involvement of commensals in the gut homeostasis. We focus on the recent findings with an intention to illuminate the mechanisms by which the microbiota and products thereof are interacting with host immunity, as well as to scrutinize imbalanced gut microbiota (dysbiosis) which lead to autoimmune disorders including inflammatory bowel disease (IBD), Type 1 diabetes (T1D) and systemic immune syndromes such as rheumatoid arthritis (RA). Results In addition to their well-recognized benefits in the gut such as occupation of ecological niches and competition with pathogens, commensal bacteria have been shown to strengthen the gut barrier and to exert immunomodulatory actions within the gut and beyond. It has been realized that impaired intestinal microbiota not only contribute to gut diseases but also are inextricably linked to metabolic disorders and even brain dysfunction. Conclusions A better understanding of the mutual interactions of the microbiota and host immune system, would shed light on our endeavors of disease prevention and broaden the path to our discovery of immune intervention targets for disease treatment.
