RESUMEN
BACKGROUND AND AIMS: Despite recent advancements in medical and surgical techniques in patients suffering from Crohn`s Disease (CD), postoperative morbidity remains relevant due to a long-standing, non-curable disease burden. As demonstrated for oncological patients, perioperative enhanced recovery concepts provide great potential to improve postoperative outcome. However, robust evidence about the effect of perioperative enhanced recovery concepts in the specific cohort of CD patients is lacking. METHODS: In a prospective single-center study, all patients receiving ileocecal resection due to CD between 2020 and 2023 were included. A specific perioperative enhanced recovery concept (ERC) was implemented and patients were divided into two groups (before and after implementation). The primary outcome focused on postoperative complications as measured by the Comprehensive Complication Index (CCI), secondary endpoints were severe complications, length of hospital stay, and rates of re-admission. RESULTS: 83 patients were analyzed of which 33 patients participated in the enhanced recovery program (postERC). While patient characteristics were comparable between both groups, ERC resulted in significantly decreased rates of overall and severe postoperative complications (CCI: 21.4 versus 8.4, p=0.0036; Clavien Dindo >2: 38% versus 3.1%, p=0.0002). Additionally, postERC-patients were earlier ready for discharge (6.5 days versus 5 days, p=0.001) and rates of re-admission were significantly lower (20% versus 3.1%, p=0.03). In a multivariate analysis, the recovery concept was identified as independent factor to reduce severe postoperative complications (p=0.019). CONCLUSION: A specific perioperative enhanced recovery concept significantly improves the postoperative outcome of patients suffering from Crohn`s Disease.
RESUMEN
El 25% de los pacientes con Enfermedades Inflamatorias Intestinales (EII) se diagnostican antes de los 20 años. En la mayor parte de los centros del país se lleva a cabo la "transferencia" del paciente desde un centro de atención pediátrico a uno de adultos. La "transición" es un criterio de calidad con beneficios en el control de la EII reduciendo el número de recaídas, de hospitalizaciones y de cirugías. Por tal motivo hemos desarrollado un Programa Interdisciplinario de Transición entre dos hospitales de referencia nacional e internacional en EII. Materiales y métodos: Entre 1/2021 y 12/ 2022 se incorporaron 24 pacientes que ingresaron en 3 fases: Fase 1 Pacientes entre 14 y 16 años asistidos en el Hospital Garrahan (HG) con un abordaje interdisciplinario. Fase 2. A partir de los 17 años se realizaron 2 (dos) encuentros en el HG en conjunto con gastroenterólogos de adultos evaluando adherencia y autonomía y la Fase 3 llevada a cabo en el Hospital B. Udaondo (HBU) sólo con el equipo de adultos luego de 6 meses de realizada la transferencia evaluando adherencia al tratamiento, consultas a emergencias, internación y/o cirugías Resultados: Al inicio del Programa el 66% de los pacientes presentaban una actividad moderada a severa vs el 8% al finalizar la fase 3. Luego de la transferencia el 12,5% necesito ingreso a guardia e internación y un 8% tratamiento quirúrgico. El 83% de los pacientes continúan en seguimiento luego de 6 meses de haber sido transferidos (AU)
Twenty-five percent of patients with inflammatory bowel diseases (IBD) are diagnosed before the age of 20 years. In most centers in the country, the "transfer" of the patient from a pediatric to an adult care center is done. However, "transition" is a quality criterion with benefits in the control of IBD by reducing the number of relapses, hospitalizations, and surgeries. For this reason, we developed an Interdisciplinary Transition Program between two national and international reference hospitals in IBD. Materials and Methods: Between January 2021 and December 2022, we incorporated 24 patients into a three-phase program. Phase 1 involved patients between 14 and 16 years of age seen at Garrahan Hospital (HG) with an interdisciplinary approach. Phase 2 began from 17 years of age, with two meetings held at HG involving adult gastroenterologists to evaluate adherence and autonomy. Phase 3 was conducted at Hospital B. Udaondo (HBU) only with the adult team, six months after the transfer, evaluating adherence to treatment, emergency consultations, hospitalizations, and/or surgeries. Results: At the beginning of the program, 66% of the patients presented with moderate to severe disease activity, compared to 8% at the end of Phase 3. After the transfer, 12.5% of the patients required emergency department visits and hospitalization, and 8% required surgical treatment. Eighty-three percent of the patients continue in the program and are still being followed up six months after the transfer (AU)

Inflammatory bowel disease (IBD) is a chronic ailment impacting the digestive system, triggered by an unusual reaction of the immune system. It includes two types of diseases: ulcerative colitis and Crohn's disease. Nonetheless, the diagnosis and evaluation of disease progression in IBD are difficult due to the absence of distinct indicators. While conventional biomarkers from blood plasma and feces, such as C-reactive protein, fecal calprotectin, and S100A12, can be employed to gauge inflammation, they are not exclusive to IBD. There is a broad consensus that intestinal microorganisms significantly contribute to the onset of intestinal imbalance, a condition intimately linked with the cause and development of IBD. Numerous studies have indicated that the makeup of intestinal microorganisms varies between individuals with IBD and those who are healthy, particularly concerning the diversity of microbes and the proportional prevalence of certain bacteria. A total of 1475 records underwent examination. Following the eligibility assessment, 17 reports were considered. The final review encompassed 12 studies, as five articles were excluded due to insufficient details regarding cases, controls, and comparability. This article suggests that gut microbiota has potential biomarkers for the noninvasive evaluation of IBD activity. Recognizing the microbiome linked with disease activity paves the way for the development of a group of microbiota-derived indicators to evaluate the initiation and advancement of IBD. This article discusses whether changes in gut microbial composition can serve as early indicators of IBD onset and progression.
RESUMEN
Inflammatory bowel disease (IBD), comprising Crohn's disease (CD) and ulcerative colitis (UC), is characterized by chronic intestinal inflammation. The dysbiotic gut microbiome likely contributes to IBD pathogenesis. Microbiome-directed therapies such as fecal microbiota transplantation (FMT), probiotics, and synbiotics may help induce and maintain remission. This systematic review aimed to determine the efficacy of microbiome interventions compared to standard therapy or placebo for IBD treatment. PubMed, EMBASE, Cochrane CENTRAL, and Web of Science were searched for randomized controlled trials on microbiome interventions in IBD from inception to October 2023. The risk of bias was assessed using Cochrane tools. Outcomes included disease activity, endoscopy, histology, quality of life, and adverse events. A total of 18 randomized controlled trials were included. Three trials found intensive (i.e., high frequency of administration and/or large volumes of fecal material) multi-donor FMT superior to autologous FMT or glucocorticoids for UC remission induction. Seven placebo-controlled trials demonstrated higher remission rates with FMT, especially intensive protocols, versus control for mild-to-moderate UC. However, a single FMT did not prevent relapses. Seven probiotic trials showed the potential to improve UC activity and maintain remission. One synbiotic trial reported reduced inflammation and symptoms versus placebo. Serious adverse events were rare. Small sample sizes and protocol heterogeneity limited the conclusions. Current evidence indicates the potential benefits of microbiome interventions, particularly intensive multi-donor FMT, for inducing and maintaining remission in UC. Probiotics may also improve outcomes. Adequately powered trials using standardized protocols are still needed to firmly establish efficacy and safety. Microbiome-directed therapies represent a promising approach for improving IBD outcomes.
RESUMEN
PURPOSE: Inflammatory bowel disease (IBD) in childhood often presents with a more extensive and more aggressive disease course than adult-onset disease. We aimed to evaluate if biological treatment started in childhood decreases the need for intestinal surgery over time. METHODS: This was a retrospective, single-center, cohort study. All pediatric patients with IBD initiated to biological therapy at the Children's Hospital, were included in the study and followed up to the first surgical procedure or re-operation in their adulthood or until 31.12.2021 when ≥ 18 of age. Data were collected from the pediatric registry of IBD patients with biologicals and medical charts. RESULTS: A total of 207 pediatric IBD patients were identified [150 with Crohn´s disease (CD), 31 with ulcerative colitis (UC), 26 with IBD unclassified (IBDU)] of which 32.9% (n = 68; CD 49, UC 13, IBDU 6) underwent intestinal surgery. At the end of a median follow-up of 9.0 years (range 2.0-25.9), patients reached a median age of 21.4 years (range 18-36). Patients who had intestinal surgery in childhood were more likely to have IBD-related surgery also in early adulthood. The duration of the disease at induction of the first biological treatment emerged as the only risk factor, with a longer duration in the surgical group than in patients with no surgery. CONCLUSION: Despite initiation of biological treatment, the risk of intestinal surgery remains high in pediatric IBD patients and often the need for surgery emerges after the transition to adult IBD clinics.

The complex relationship between periodontitis (PD) and inflammatory bowel disease (IBD) has received significant attention in recent studies. Emerging evidence suggests that the oral-gut axis plays a pivotal role in their interaction. This review provides a comprehensive, up-to-date analysis of original research from 2003 to 2023 on the PD-IBD relationship and aims to be a reference for future research. Relevant literature was sourced from the PubMed database using the keywords "periodontitis" and "inflammatory bowel disease". Additionally, a manual library search and a review of bibliographies were conducted. Of the 297 articles retrieved, 27 studies were chosen for final review. Out of these, 21 studies (78%), including both in vitro and in vivo research, indicated an association between PD and IBD. While many studies confirm a bi-directional relationship, others refute it or deem it clinically irrelevant. There is a need for more accessible studies, such as randomized trials, which also investigate the factors that could influence the outcomes to clarify the exact molecular mechanisms and clinical implications of this complex relationship.
RESUMEN
Vedolizumab (VDZ) is used off-label in pediatric inflammatory bowel disease (PIBD). There are less data on drug levels to achieve and maintain remission in children. We aimed to study vedolizumab (VDZ) trough levels in a pediatric population in a real-life setting. We traced 50 patients with PIBD receiving VDZ treatment at our hospital, reviewed their treatment protocol, trough levels, and antidrug antibodies, and compared those to fecal calprotectin (FC) levels and achievement of corticosteroid-free maintenance therapy (CF). VDZ trough level was available from 198 samples during a median follow- up of 12.6 months. Proceeding to maintenance therapy was associated with a decline in FC but not with VDZ trough levels that were comparable between patients with FC < 100 µg/g (remission), 100-1000 µg/g, or > 1000 µg/g at 3 months (mean levels of 36.8, 28.6, and 27 µg/mL, respectively p = 0.188). At 3 months, patients achieving CF (41%) and those on corticosteroids had comparable VDZ trough levels (33 vs. 27.5 µg/mL, respectively). At 6 months, the trough level was similar in groups with FC < 100 µg/g or FC > 1000 µg/g (31.5 and 27.6 µg/mL, p = 0.859). Treatment intensification did not improve the achieved CF at 12 months. None developed drug antibodies nor discontinued the therapy for an adverse event. Conclusion: VDZ was a well-tolerated and safe biologic treatment. A positive response on gut inflammation after induction predicted proceeding to maintenance therapy whereas trough levels did not. A VDZ trough level associated with clinical remission or continuing with VDZ treatment could not be determined. What is Known: ⢠In pediatric inflammatory bowel disease, vedolizumab is still in off-label use. ⢠The results on the relationship between drug levels of vedolizumab and clinical remission in pediatric patients are contradictory. What is New: ⢠This real-life setting in pediatric-onset inflammatory bowel disease showed no benefit of therapy enhancement during a median follow-up of one year. ⢠Trough levels of vedolizumab were not associated with therapy outcomes.

INTRODUCTION: The STRIDE consensus suggested to focus on mucosal healing, based on biomarkers and endoscopy, in addition to clinical endpoints as treatment target. This narrative review provides a critique of this concept in Crohn´s disease. AREAS COVERED: We analyze and discuss the limitations of endpoints as targets, their currently limited achievability, and the controversial evidence relating to 'treat to target.' The relevant publications in Pubmed were identified in a literature review with the key word 'Crohn´s disease.' EXPERT OPINION: All targets and endpoints have their limitations, and, even if reached, not all have unequivocally been shown to improve prognosis. The major deficiency of STRIDE is not only the lack of validation and agreement upon endpoints but little evidence of their achievability in a sizable proportion of patients by dose or timing adjustments or switching the medication. Above all, the concept should be based on clear evidence that patients indeed benefit from appropriate escalation of treatment and relevant controlled studies in this regard have been controversial. Until the STRIDE approach is proven to be superior to standard treatment focusing on clinical well-being, the field should remain reluctant and expect more convincing evidence before new targets are approved.

BACKGROUND: Non-alcoholic fatty liver disease (NAFLD) is a common concomitant condition in patients with inflammatory bowel disease (IBD). We aim to assess the magnitude of this association. METHODS: We searched MEDLINE, EMBASE and Scopus libraries for the period up to February 2023 to identify studies reporting cohorts of IBD patients in which NALFLD was evaluated. RESULTS: Eighty-nine studies were analyzed. The overall prevalence of NAFLD was 24.4% (95%CI, 19.3-29.8) in IBD, 20.2% (18.3-22.3) in Crohn's disease and 18.5% (16.4-20.8) for ulcerative colitis. Higher prevalence was found in male compared to female patients, in full papers compared to abstracts, and in cross-sectional studies compared to prospective and retrospective ones. The prevalence of NAFLD in IBD has increased in studies published from 2015 onwards: 23.2% (21.5-24.9) vs. 17.8% (13.2-22.9). Diagnostic methods for NAFLD determined prevalence figures, being highest in patients assessed by controlled attenuation parameter (38.8%; 33.1-44.7) compared to ultrasonography (28.5%; 23.1-34.2) or other methods. The overall prevalence of fibrosis was 16.7% (12.2-21.7) but varied greatly according to the measurement method. CONCLUSION: One-quarter of patients with IBD might present with NAFLD worldwide. This proportion was higher in recent studies and in those that used current diagnostic methods.

BACKGROUND: Disturbed bile acid homeostasis associated with a rise of primary and a decline of secondary bile acids is a consistent finding in inflammatory bowel diseases (IBDs). Whether fecal bile acids may emerge as biomarkers for IBD diagnosis and disease severity is less clear. Our study aimed to identify associations of 18 fecal bile acid species with IBD entity and disease activity. METHODS: Stool samples of 62 IBD patients and 17 controls were collected. Eighteen fecal bile acid species were quantified by LC-MS/MS using stable isotope dilution. Lipid levels normalized to a dry weight of the fecal homogenates and ratios of single bile acid species to total bile acid levels were used for calculations. RESULTS: IBD patients exhibited altered primary and secondary bile acid ratios in stool, with notable distinctions between ulcerative colitis (UC) compared to Crohn's disease (CD) and healthy controls. Fecal calprotectin was negatively correlated with glycolithocholic acid (GLCA) and hyodeoxycholic acid (HDCA) in UC. These bile acids were reduced in stool of UC patients with fecal calprotectin levels > 500 µg/g compared to UC patients with low calprotectin levels. Moreover, negative associations of six secondary bile acids with C-reactive protein (CRP) existed in UC. In CD patients, fecal bile acids did not correlate with CRP or fecal calprotectin. Diarrhoea is common in IBD, and UC patients with diarrhoea had reduced deoxycholic acid (DCA), glycine conjugated DCA (GDCA) and lithocholic acid in stool in contrast to patients with normal stool consistency. Fecal bile acid levels were not associated with diarrhoea in CD patients. UC patients treated with mesalazine had increased levels of fecal GDCA whereas no such changes were observed in CD patients. Bile acid levels of CD and UC patients treated with biologicals or corticosteroids did not change. Relative levels of GHDCA (specificity: 79%, sensitivity: 67%) and glycochenodeoxycholic acid (specificity: 74%, sensitivity: 63%) were the most specific to distinguish UC from CD. CONCLUSION: Disrupted fecal bile acid homeostasis is associated with disease severity and disease symptoms in UC but not in CD, potentially aiding in distinguishing IBD subtypes and classifying the pathophysiology of diarrhoea in UC.

BACKGROUND: Urinary 3-indoxyl sulfate levels as well as fecal short chain fatty acid (SCFA) concentrations are surrogate markers for gut microbiota diversity. Patients with inflammatory bowel diseases (IBDs) and patients with primary sclerosing cholangitis (PSC), a disease closely associated with IBD, have decreased microbiome diversity. In this paper, the fecal SCFAs propionate, acetate, butyrate and isobutyrate of patients with IBD and patients with PSC-IBD and urinary 3-indoxyl sulfate of IBD patients were determined to study associations with disease etiology and severity. METHODS: SCFA levels in feces of 64 IBD patients and 20 PSC-IBD patients were quantified by liquid chromatography with tandem mass spectrometry (LC-MS/MS). Urinary 3-indoxyl sulfate levels of 45 of these IBD patients were analysed by means of reversed-phase liquid chromatography-electrospray ionization-tandem mass spectrometry. Feces of 17 healthy controls and urine of 13 of these controls were analyzed in parallel. These cohorts had comparable sex distribution and age. RESULTS: Urinary 3-indoxyl sulfate concentrations (normalized to urinary creatinine levels) was increased (P = 0.030) and fecal isobutyrate levels (normalized to dry weight of the stool sample) of IBD patients were decreased (P = 0.035) in comparison to healthy controls. None of the analyzed metabolites differed between patients with Crohn´s disease (CD) and patients with ulcerative colitis (UC). Fecal acetate and butyrate positively correlated with fecal calprotectin (P = 0.040 and P = 0.005, respectively) and serum C-reactive protein (P = 0.024 and P = 0.025, respectively) in UC but not CD patients. UC patients with fecal calprotectin levels above 150 µg/g, indicating intestinal inflammatory activity, had higher fecal acetate (P = 0.016), butyrate (P = 0.007) and propionate (P = 0.046) in comparison to patients with fecal calprotectin levels < 50 µg/g. Fecal SCFA levels of PSC-IBD and IBD patients were comparable. CONCLUSIONS: Current findings suggest that analysis of urinary 3-indoxyl-sulfate as well as fecal SCFAs has no diagnostic value for IBD and PSC-IBD diagnosis or monitoring of disease severity.

INTRODUCTION: Most guidelines for IBD still recommend step-by-step therapy with initially classic drugs such aminosalicylates (in ulcerative colitis) or steroids but avoid prioritizing certain biological drugs and JAK inhibitors in the complicated course. This review provides an aid to pending therapy decisions. AREAS COVERED: In this review, we analyze the evidence for Crohn's disease as well as ulcerative colitis in order to optimize and 'personalize' the choice of therapy, especially in difficult cases. The relevant publications in Pubmed were identified in a continuous literature review with the key words 'Crohn´s disease' and 'ulcerative colitis.' EXPERT OPINION: Based on this complex data set following standard therapies steroid-refractory Crohn´s disease should preferentially be treated with combined infliximab plus azathioprine or risankizumab, in second line after their failure with ustekinumab or 7adalimumab. In steroid-refractory ulcerative colitis infliximab plus azathioprine or upadacitinib should be preferred in first line, filgotinib, tofacitinib or ustekinumab in second line. A steroid-dependent course in both diseases requires azathioprine or vedolizumab, in second line infliximab or Janus kinase inhibitors. The conclusions drawn from these complex data may be helpful for individual decision making in daily clinical practice.

Background: Previous epidemiological observational studies have reported an association between inflammatory bowel disease (IBD) and prostate cancer (PCa), but the causality is inconclusive. The purpose of this study was to evaluate the causality of IBD on PCa using the mendelian randomization (MR) analysis. Methods: We performed a two-sample MR analysis with public genome-wide association studies (GWAS) data. Eligible instrumental variables (IVs) were selected according to the three assumptions of MR analysis. The inverse-variance weighted (IVW) method was the main method. Complementary methods included the MR-Egger regression, the Weighted Median, the Simple Mode, the Weighted Mode and MR pleiotropy residual sum and outlier (MR-PRESSO) methods. Results: Genetically determined IBD did not have a causal effect on PCa (IVW P > 0.05). Additionally, there was no causal effect of Crohn's disease (CD) and ulcerative colitis (UC) on PCa in the MR analysis (IVW P > 0.05). Results of complementary methods were consistent with those of the IVW method. Conclusions: This study does not support a causal association of IBD on PCa, which is in contrast to most observational studies.

BACKGROUND: Patients with inflammatory bowel disease report multiple symptoms, but the relationships among co-occurring symptoms are poorly understood. This study aimed to examine the prevalence of symptoms and explore symptom clusters and possible associations between symptom clusters and socio-demographic and clinical variables in patients newly diagnosed with inflammatory bowel disease. METHODS: The IBSEN III study is a prospective population-based inception cohort of patients with inflammatory bowel disease. This study used patient data from the three largest hospitals in the study catchment area. The Memorial Symptom Assessment Scale was used to assess the prevalence of symptoms. Symptom clusters were identified using principal component analysis. Possible associations between socio-demographic and clinical variables and symptom cluster membership were estimated using regression analysis. RESULTS: Of the 573 patients (age, ≥18 years) diagnosed with inflammatory bowel disease, 350 (61.1%) completed the questionnaire (responders). Eleven symptoms were reported by >50% of the responders. The three most prevalent symptoms were bloating (84%), drowsiness (81%), and lack of energy (81%). Three symptom clusters were identified: psychological (56% of the patients), impaired energy (28%), and physical (16%) clusters. Multinomial regression analysis revealed that vitamin D deficiency was significantly associated with the impaired energy cluster (odds ratio=2.49, 95% confidence interval [1.00-6.2], p=0.05). CONCLUSIONS: We found high symptom prevalence in patients newly diagnosed with inflammatory bowel disease. Three distinct symptom clusters were identified, and the psychological cluster includes >50% of the patients. Vitamin D deficiency is the only factor associated with cluster membership, namely the impaired energy cluster.

Background: Crohn's disease (CD), a chronic gastrointestinal inflammatory disease, is increasing in China. With a focus on Han Chinese families with CD, the aim of this study was to find genetic variations that increase CD susceptibility by genome sequencing, genetic association, expression, and functional research. Materials and methods: We performed family-based genome sequencing (WGS) analysis on 24 patients with CD from 12 families and then filtered shared potential causal variants by incorporating association results from meta-analyses of CD GWAS and immunology genes and in silico variant effect prediction algorithms. Replication analyses were performed in an independent cohort including 381 patients with CD and 381 control subjects. Results: There were 92 genetic variants significantly associated with CD in Chinese individuals. Among them, 61 candidate loci were validated in replication analyses. As a result, patients carrying a rare frameshift variant (c.1143_1144insG; p. Leu381_Leu382fs) in gene SIRPB1 had significantly higher risk to develop CD (p = 0.03, OR 4.59, 95% CI 0.98-21.36, 81.82% vs. 49.53%). The frameshift variation induced tyrosine phosphorylation of Syk, Akt, and Jak2, elevated the expression of SIRPB1 at the mRNA and protein levels, activated DAP12, and controlled the activation of NF-κB in macrophages. Additionally, it promoted the synthesis of the pro-inflammatory cytokines IL-1, TNF-, and IL-6. Conclusion: Our results suggest that the rare gain-of-function frameshift variant in SIRPB1 is associated in Han Chinese patients with CD. The functional mechanism of SIRPB1 and its downstream inflammatory pathways was preliminarily explored in CD.
RESUMEN
OBJECTIVE: This study aimed to find the key genes and miRNAs as potential biomarkers related to the progression of colorectal cancer (CRC) from Crohn's disease (CD). BACKGROUND: CD is widely accepted as one of the main risk factors leading to CRC. So, Identifying the novel molecular pathways involved in the development of CRC from CD can provide potential solutions for therapeutic interventions. METHODS: By implementing a systematic approach, we have analyzed mRNA and miRNA datasets containing CRC and CD samples to determine differentially expressed genes (DEGs) and miRNAs (DEmiRNA). Then by selecting common genes involved in the progression from CD to CRC, different downstream analyses including mRNA-miRNA network, functional enrichment analysis, gene set enrichment analysis, and survival analysis were performed. Finally, quantitative real-time PCR (RT-PCR) analysis of tissue samples obtained from Normal/CRC samples was used to confirm the differential expression of selected genes and miRNA. RESULTS: There were 10 DE miRNA and 181 genes DEGs common between progression from CD to CRC. The genes obtained for each of the 10 miRNAs were considered as the final target for downstream analyzes. In addition, analysis of RT-PCR indicated that miR-195-5p, PHLPP2, and LITAF were downregulated in the cancer group compared to the control group. CONCLUSION: This study showed that PHLPP2, LITAF, and miR-195-5p may have key roles in the tumorigenesis of CRC and they can be used as therapeutic targets and diagnostic biomarkers after further in-vitro and in-vivo evaluation.

Background: Due to inconsistent findings in observational studies regarding the relationship between inflammatory bowel disease (IBD), encompassing ulcerative colitis (UC) and Crohn's disease (CD), and COVID-19, our objective is to explore a potential causative correlation between IBD and COVID-19 susceptibility and its severity using a two-sample Mendelian randomization (MR) analysis. Methods: Using summary data from genome-wide association studies, IBD, including UC and CD, were used as exposure instruments, while COVID-19 susceptibility, hospitalization, and very severe illness were employed as the outcome. The five analysis methods were adopted to evaluate the causal relationship between two diseases, with the inverse variance weighted (IVW) method being the most important. Also, sensitivity analyses were done to make sure that the main results of the MR analyses were reliable. Results: In the analysis using five methods, all p-values were higher than 0.05. There was no association between IBD and COVID-19 susceptibility, hospitalization, and severity in our MR study. The random-effect model was applied due to the existence of heterogeneity. MR-Egger regression revealed no indication of directional pleiotropy, and sensitivity analysis revealed similar relationships. Conclusion: This MR study found no evidence to support that IBD (which includes UC and CD) increases the risk of COVID-19 susceptibility or severity. Our result needs further confirmation through larger epidemiological studies.

Background and objective The global health burden of inflammatory bowel disease (IBD) stems from its increasing incidence over the years. Comprehensive studies on the topic hypothesize that IBD plays a more dominant in the development of non-alcoholic fatty liver disease (NAFLD) and non-alcoholic steatohepatitis (NASH). In light of this, we conducted this study with the aim of assessing the prevalence and risk factors of developing NASH in patients who have had a diagnosis of ulcerative colitis (UC) and Crohn's disease (CD). Methodology A validated multicenter and research platform database of more than 360 hospitals from 26 different healthcare systems across the United States from 1999 to September 2022 was utilized for conducting this study. Patients aged 18-65 years were included. Pregnant patients and individuals diagnosed with alcohol use disorder were excluded. The risk of developing NASH was calculated using a multivariate regression analysis to account for potential confounding variables including male gender, hyperlipidemia, hypertension, type 2 diabetes mellitus (T2DM), and obesity. A two-sided p-value <0.05 was considered statistically significant, and all statistical analyses were performed using R version 4.0.2 (R Foundation for Statistical Computing, Vienna, Austria, 2008). Results A total of 79,346,259 individuals were screened in the database and 46,667,720 were selected for the final analysis based on the inclusion and exclusion criteria. Using multivariate regression analysis, the risk of developing NASH among patients with UC and CD was calculated. The odds of having NASH among patients with UC was 2.37 (95% CI: 2.17-2.60, p<0.001). Similarly, the odds of having NASH were high in patients with CD as well, at 2.79 (95% CI: 2.58-3.02, p<0.001). Conclusion Based on our findings, patients with IBD have an increased prevalence and higher odds of developing NASH after controlling for common risk factors. We believe that a complex pathophysiological relationship exists between both disease processes. Further research is required to establish appropriate screening times to enable earlier disease identification and thereby improve patient outcomes.
RESUMEN
This review summarizes the evidence about telemonitoring in patients with inflammatory bowel disease (IBD). To give an overview of the advances performed, as well as the enablers and barriers which favoured/hindered telemonitoring implementation. We performed a literature search in PubMed, EMBASE, MEDLINE, Cochrane Database, Web of Science and Conference Proceedings. Titles and abstracts published up to September 2022 were screened for a set of inclusion criteria: telemonitoring intervention, IBD as the main disease, and a primary study performed. Ninety-seven reports were selected for full review. Finally, 20 were included for data extraction and critical appraisal. Most studies used telemonitoring combined with tele-education, and programs evolved from home telemanagement systems towards web portals through mHealth applications. Web systems demonstrated patients' acceptance, improvement in quality of life, disease activity and knowledge, with a good cost-effectiveness profile in the short-term. Initially, telemonitoring was almost restricted to ulcerative colitis, but new patient reported outcome measures, home-based tests and mobile devices favoured its expansion to different patients´ categories. However, technological and knowledge advances led to legal, ethical, economical and logistic issues. Standardization of remote healthcare is necessary, to improve the interoperability of systems as well as to address liability concerns and users´ preferences. Telemonitoring IBD is well accepted and improves clinical outcomes at a lower cost in the short-term. Funders, policymakers, providers, and patients need to align their interests to overcome the emerging barriers for its full implementation.
