Abstract
BACKGROUND AND AIMS Tofacitinib (TFB) appears to be effective in the treatment of ulcerative colitis (UC); however, available real-world studies are limited by cohort size. TFB could be an option in the treatment of acute severe ulcerative colitis (ASUC). We aimed to investigate efficacy and safety of TFB in moderate-to-severe colitis and ASUC. METHODS This retrospective, international cohort study enrolling UC patients with ≥6-week follow-up period was conducted from February 1 to July 31, 2022. Indications were categorized as ASUC and chronic activity (CA). Baseline demographic and clinical data were obtained. Steroid-free remission (SFR), colectomy, and safety data were analyzed. RESULTS A total of 391 UC patients (median age 38 [interquartile range, 28-47] years; follow-up period 26 [interquartile range, 14-52] weeks) were included. A total of 27.1% received TFB in ASUC. SFR rates were 23.7% (ASUC: 26.0%, CA: 22.8%) at week 12 and 41.1% (ASUC: 34.2%, CA: 43.5%) at week 52. The baseline partial Mayo score (odds ratio [OR], 0.850; P = .006) was negatively associated with week 12 SFR, while biologic-naïve patients (OR, 2.078; P = .04) more likely achieved week 52 SFR. The colectomy rate at week 52 was higher in ASUC group (17.6% vs 5.7%; P < .001) and decreased with age (OR, 0.94; P = .013). A total of 67 adverse events were reported, and 17.9% resulted in cessation of TFB. One case of thromboembolic event was reported. CONCLUSIONS TFB is effective in both studied indications. TFB treatment resulted in high rates of SFR in the short and long terms. Higher baseline disease activity and previous biological therapies decreased efficacy. No new adverse event signals were found.

Therapeutic Drug Monitoring as a Tool for the Clinical Outcome Prediction in Vedolizumab-Treated Patients: An Italian Pilot Study. Biomedicines 2024; 12:824. [PMID: 38672179 PMCID: PMC11048400 DOI: 10.3390/biomedicines12040824] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/29/2024] [Revised: 04/05/2024] [Accepted: 04/06/2024] [Indexed: 04/28/2024] Open
Abstract
Over the years, vedolizumab (VDZ) has emerged as a more effective target therapy for inflammatory bowel disease. The aim of this work was to analyze a cohort of inflammatory bowel disease patients, evaluating the association between VDZ serum concentrations at 6 months from starting therapy and their clinical and biochemical indexes within one year of treatment, correlating drug levels with response and clinical remission. Forty patients treated with VDZ were enrolled. Drug concentrations were quantified through ELISA methods. VDZ levels correlated with hemoglobin levels at twelve months of therapy (p = 0.03) and with clinical remission at twelve months of therapy (p = 0.03); patients who reached clinical remission showed higher VDZ concentrations. A VDZ cut-off value of 43.1 μg/mL was suggested, predicting clinical remission at twelve months of therapy. A statistically significant association between VDZ levels at T6 and calprotectin <250 μg/g at T12 was found (p = 0.04). Furthermore, the optimal threshold value of VDZ levels at T6 associated with calprotectin <250 μg/g at T12 was identified: through levels higher than 45.2 µg/mL, we were able to predict remission one year after therapy. In the final regression multivariate model, no factor was retained as a predictor of clinical remission at one year of treatment. In conclusion, this is the first pilot study reporting a possible VDZ serum cut-off value able to predict not only the clinical remission at twelve months of therapy but also the calprotectin level, which is very important, as it is a surrogate marker of mucosal healing.

Abstract
Mounting evidence indicates that periodontitis-related oral bacteria may contribute to gut microbial dysbiosis. This clinical study aimed to explore the oral-gut microbial signatures associated with periodontitis and to longitudinally evaluate the effect of periodontal treatment on the oral and gut microbial composition. Stool and saliva samples from generalized stage III/IV periodontitis patients (n = 47) were collected and analyzed by 16S ribosomal RNA gene amplicon sequencing, before and 3 mo after steps I to II of periodontal therapy. Periodontally healthy matched subjects (n = 47) were used as controls. Principal component analysis was carried out to identify oral-gut microbial profiles between periodontitis patients at baseline and healthy subjects; periodontitis samples were longitudinally compared before and after treatment. β-Diversity of gut microbial profiles of periodontitis patients before treatment significantly differed from healthy controls (P < 0.001). Periodontal therapy was associated with a significant change in gut microbiota (P < 0.001), with post-treatment microbial profiles similar to healthy volunteers. A higher abundance of Bacteroides, Faecalibacterium, Fusobacterium, and Lachnospiraceae was noted in fecal samples of periodontitis patients at baseline compared to healthy controls. In contrast, Lactobacillus was the only genus more abundant in the latter. Additionally, periodontal therapy led to a parallel reduction in the salivary carriage of periodontal pathobionts, as well as gut Bacteroides, Lachnoclostridium, Lachnospiraceae, Oscillospiraceae, and Ruminococcaceae, to levels similar to healthy controls. Collectively, discriminating oral-gut microbial signatures of periodontitis were found. Periodontal treatment both mitigated oral dysbiosis and altered gut microbial composition, signifying potential broader implications for gastrointestinal health and disease.

Rates of Adverse Events in Patients With Ulcerative Colitis Undergoing Colectomy During Treatment With Tofacitinib vs Biologics: A Multicenter Observational Study. Am J Gastroenterol 2024:00000434-990000000-01014. [PMID: 38305302 DOI: 10.14309/ajg.0000000000002676] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/17/2023] [Accepted: 12/28/2023] [Indexed: 02/03/2024]
Abstract
INTRODUCTION Patients with ulcerative colitis (UC) receiving immunosuppressive drugs are at substantial risk of colectomy. We aimed to assess the risk of postoperative complications of tofacitinib exposure before colectomy in comparison with biologics. METHODS A multicenter, retrospective, observational study was conducted in patients with UC who underwent total colectomy for medically refractory disease, exposed to tofacitinib or a biologic before surgery. Primary outcome was the occurrence of any complication within 30 (early) and 90 (late) days after surgery. Secondary outcomes were the occurrence of infections, sepsis, surgical site complications, venous thromboembolic events (VTE), hospital readmissions, and redo surgery within the same timepoints. RESULTS Three hundred one patients (64 tofacitinib, 162 anti-tumor necrosis factor-α agents, 54 vedolizumab, and 21 ustekinumab) were included. No significant differences were reported in any outcome, except for a higher rate of early VTE with anti-tumor necrosis factor-α agents ( P = 0.047) and of late VTE with vedolizumab ( P = 0.03). In the multivariate analysis, drug class was not associated with a higher risk of any early and late complications. Urgent colectomy increased the risk of any early (odds ratio [OR] 1.92, 95% confidence interval [CI] 1.06-3.48) complications, early hospital readmission (OR 4.79, 95% CI 1.12-20.58), and early redo surgery (OR 7.49, 95% CI 1.17-47.85). A high steroid dose increased the risk of any early complications (OR 1.96, 95% CI 1.08-3.57), early surgical site complications (OR 2.03, 95% CI 1.01-4.09), and early redo surgery (OR 7.52, 95% CI 1.42-39.82). Laparoscopic surgery decreased the risk of any early complications (OR 0.54, 95% CI 0.29-1.00), early infections (OR 0.39, 95% CI 0.18-0.85), and late hospital readmissions (OR 0.34, 95% CI 0.12-1.00). DISCUSSION Preoperative tofacitinib treatment demonstrated a postoperative safety profile comparable with biologics in patients with UC undergoing colectomy.

Abstract
Helicobacter pylori (H. pylori) infection is a prominent entity within human infectious diseases which cause chronic gastritis, peptic ulcers, gastric malignancies, and extragastric disorders. Its persistent colonization can lead to a systemic inflammatory cascade, potentially instigating autoimmune responses and contributing to the pathogenesis of autoimmune diseases. While the specific etiopathogenesis of inflammatory bowel diseases (IBDs) is still unknown, it is widely recognized that immunological, genetic, and environmental factors are implicated. Various bacterial and viral pathogens have been implicated in the pathogenesis of IBDs. Numerous studies suggest a correlation between H. pylori infection and IBDs. While subject to debate, this link suggests that the bacterium's presence somehow impacts the progression of IBDs by modifying the diversity of the gut microbiota, consequently altering local chemical profiles and disrupting the pattern of gut immune response. However, epidemiological evidence indicates a protective role of H. pylori infection against the onset of autoimmune diseases. Additionally, laboratory findings demonstrate H. pylori's capacity to promote immune tolerance and restrict inflammatory reactions. The aim of this review is to elucidate the proposed mechanisms and confounding factors that underlie the potential association between H. pylori infection and IBDs.

Abstract
Eosinophilic colitis (EC) is the rarest among primary eosinophilic gastrointestinal disorders (EGID). EC is underdiagnosed due to its blurred and proteiform clinical manifestations. To explore the clinical and atopic characteristic of EC adult patients, the diagnostic delay, and relapse-associated factors, by comparison with patients with eosinophilic esophagitis (EoE) and irritable bowel syndrome (IBS). EC patients followed-up at four clinics were included, and clinical, histopathological, and laboratory data were retrieved. As control groups, age-matched patients with EoE and IBS were recruited. Allergy tests included skin prick test and serum specific IgE. Diagnostic delay was assessed. Overall, data from 73 patients were retrieved, including 40 with EC (median age 39 years IQR 22.5-59, F:M 2.1:1), 12 with EoE (F:M ratio: 1:5), and 21 with IBS (F:M ratio: 1:0.9). The most common features in EC patients were female sex (67.5%), atopy (77.5%), abdominal pain/distention (70%), diarrhoea (77.5%), and faecal calprotectin elevation (22.5%). Blood eosinophils were elevated in EoE, but not in EC (p < 0.001), while ECP did not differ across the three groups (p = 0.4). The frequency of allergen sensitization reached 25% of patients. Several frequent pan-allergens for this region were present. The overall diagnostic delay was 10 months (IQR 4-15). Factors contributing to a greater diagnostic delay were atopy, weight loss, and a previous misdiagnosis. EC is mostly a diagnosis of exclusion, burdened by a substantial diagnostic delay. In female patients the presence of allergen sensitization, abdominal symptoms and faecal calprotectin elevation should raise the suspicion of EC.

Hyper Mucinous Proliferations in the Mucosa of Patients with Inflammatory Bowel Disease: Histological Lesions with a Real Potential for Neoplastic Evolution? Diagnostics (Basel) 2024; 14:499. [PMID: 38472971 DOI: 10.3390/diagnostics14050499] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/20/2024] [Revised: 02/15/2024] [Accepted: 02/20/2024] [Indexed: 03/14/2024] Open
Abstract
BACKGROUND AND AIMS Mucin disfunction is a critical event in the pathogenesis of inflammatory bowel disease (IBD). Although hyper mucinous conditions have a still debated implication in the clinical evolution of this disorder, hyper mucinous villous proliferations were found to have a preneoplastic biologic potential. We studied morphologic and immunophenotypic characteristics of these lesions in ileocolonic resections for IBD to add evidence about the evolutive potential of these lesions in samples with well oriented wall structures. METHODS Morphologic characteristics of bowel samples from 20 patients resected for IBD and with raised lesions at gross examination were studied and sections from cases with hyper mucinous lesions were stained with the following antibodies: Ki 67, p21, and p27, which were employed to evaluate the characteristics of the proliferative and differentiative activity of the epithelial structures; mismatch repair proteins and p53 have been studied as proteins implicated in carcinogenesis in IBD-affected mucosa; mucins subtypes in hyper mucinous structures were evaluated with MUC-2 and MUC-6. The results in 11 cases of saplings were that they harbored hyper mucinous proliferations. The occurrence of hyper mucinous structures was not related to dysplastic lesions, pseudo pyloric metaplasia, subtype of disease, or activity. In only one of our cases, mild cytologic atypia in the proliferative compartment was detected. Proliferation markers (Ki 67, p53) were expressed in the proliferative compartments of mucosal crypts and antiproliferative proteins p21 and p27 were expressed in differentiated epithelium. MMR proteins expression was limited to the proliferative compartment of the hyper mucinous projections. Mucin subtypes distribution was regular in the epithelium of hyper mucinous proliferations. CONCLUSIONS The present monocentric retrospective study was conducted on surgical samplings with well oriented crypts. Collected data show that hyper mucinous features are frequent occurrences in raised lesions in IBD patients. In hyper mucinous proliferations of the selected cases, the status of the proliferative cycle, the expression of the proteins most frequently involved in carcinogenetic pathways of mucosa affected by IBD, and the mucins subtypes expression have no evident anomalies. Findings are not consistent with the increased risk of neoplastic evolution observed in other studies; rather, they suggest a hyperplastic nature. However, the capacity of hyper mucinous raised lesions for neoplastic evolution should be ruled out with more extensive prospective studies to identify functional defects that could explain the hypothesized neoplastic potential.

Abstract
BACKGROUND Metabolic dysfunction associated steatotic liver disease (MASLD) is associated with an increased risk of coronary artery disease. Computed Tomography Coronary Angiography (CTCA) can assess both the extent and the features of coronary plaques. We aimed to gather evidence about the prevalence and features of coronary plaques among MASLD patients. METHODS PubMed, Scopus, and Google Scholar databases were searched for randomized controlled trials and adjusted observational studies assessing the prevalence and features of coronary plaques by means of CTCA in MASLD patients as compared with a control group. The prevalence of coronary stenosis (defined as >30% and >50% diameter of stenosis), of increasing coronary artery calcium (CAC) score and of high-risk features (namely low-attenuation plaques, napkin ring sign, spotty calcification and positive remodelling) in MASLD patients were the endpoints of interest. RESULTS Twenty-four observational studies were included. MASLD was associated with an increased prevalence of critical coronary stenosis compared with controls (odds ratio [OR] 1.54, 95%CI 1.23-1.93). Increased values of CAC score were observed in MASLD patients (OR 1.35, 95%CI 1.02-1.78 and OR 2.26, 95%CI 1.57-3.23 for CAC score 0-100 and >100, respectively). An increased risk of 'high-risk' coronary plaques was observed in MASLD patients (OR 2.13, 95%CI 1.42-3.19). As high-risk features plaques, a higher prevalence of positive remodelling and spotty calcification characterize MASLD patients (OR 2.92, 95%CI 1.79-4.77 and OR 2.96, 95%CI 1.22-7.20). CONCLUSIONS Patients with MASLD are at increased risk of developing critical coronary stenosis and coronary plaques characterized by high-risk features as detected by CTCA.

Abstract
(1) Background: Inflammatory bowel diseases (IBDs) are chronic inflammatory disorders involving innate and adaptive immune responses. Despite primarily affecting the gut, recent insights highlight systemic implications, expanding our understanding beyond intestinal boundaries. (2) Methods: This retrospective multicentric study explored the association of IBD and immune-mediated inflammatory diseases (IMIDs) and the impact of concurrent IMIDs on the course of IBD. Clinical data were collected from consecutive medical records of patients with IBD. For assessing the impact of concurrent IMIDs, a control group of IBD patients without associated IMIDs was considered. (3) Results: Of 6589 IBD patients, 6.8% exhibited concomitant IMIDs. Notably, 79.8% of these patients had an aggressive disease course. Psoriasis, atopic dermatitis, and type 1 diabetes mellitus prevalence were lower in the IBD population than in the general population. Conversely, multiple sclerosis, primary sclerosing cholangitis, and pyoderma gangrenosum were more prevalent in IBD patients. Among the patients with a concomitant IMID, 79.8% had an aggressive disease course vs. 8.1% in the control group (p < 0.001). (4) Conclusions: This study underscores the frequency of IMIDs in IBD patients and their association with a more aggressive disease course. The recognition of concurrent IMIDs is crucial for comprehensive patient management, influencing therapeutic decisions and potentially improving outcomes.

Abstract
Although the role of vitamin D (VD) in the pathogenesis and progression of Crohn's disease (CD) is known, the association between single-nucleotide polymorphisms (SNPs) of genes linked to vitamin D pathway and CD risk is still under study. Furthermore, no significant association has been previously found between these SNPs and perianal CD (pCD), a severe phenotypic manifestation of CD that may present as perianal fistula, abscess, and recto-vaginal fistula. Among the mechanisms involved in its pathogenesis, local inflammation and intestinal microbiota alteration are recognized. VD seems to act on these elements. The aim of this study was to evaluate the presence of an association between SNPs of genes coding for enzymes, transporters, and receptors involved in the VD pathway and the occurrence of pCD. Blood samples of 206 patients with CD, including 34 with pCD, were analyzed for VDR, CYP27B1, CYP24A1, and GC genetic variants. VDR Apal Aa genotype and VDR BsmI Bb genotype resulted in an association with pCD (p = 0.01 and p = 0.02, respectively). Our study demonstrates for the first time the impact of the polymorphisms of genes associated with the VD pathway on the onset of pCD. Future multicenter studies are needed to confirm these data.

Abstract
BACKGROUND The administration of biological drugs in inflammatory bowel diseases (IBD) is increasingly moving from intravenous to subcutaneous formulations. AIMS To evaluate the efficacy and safety of vedolizumab subcutaneous administration after switching from intravenous administration in ulcerative colitis (UC) patients in corticosteroid-free clinical remission. METHODS An observational, multicentre, prospective study was conducted by the Italian Group for the study of IBD (IG-IBD). UC patients in clinical remission (pMAYO < 2) not receiving steroids for > 8 months before the switch, and with at least 6 months of follow-up were included. Switch from intravenous to subcutaneous vedolizumab was defined as successful in patients not experiencing a disease flare (pMAYO ≥ 2) or needing oral steroids or stopping subcutaneous vedolizumab during the 6 months of follow-up after the switch. RESULTS Overall, 168 patients were included. The switch was a success in 134 patients (79.8%). Vedolizumab retention rate was 88.7% at month six. C-reactive protein and faecal calprotectin values did not change after the switch (p = 0.07 and p = 0.28, respectively). Ten of the 19 patients who stopped subcutaneous formulation switched back to intravenous formulation recapturing clinical remission in 80%. Side effects were observed in 22 patients (13.1%). CONCLUSION Effectiveness of switching from intravenous to subcutaneous vedolizumab formulation in UC patients in steroid-free clinical remission is confirmed in a real-world setting.

The Histology-Driven Differential Diagnosis in Bowel Inflammatory Conditions Is Not All That Obvious: Evidence from a Survey Based on Digital Slides. Diagnostics (Basel) 2023; 13:3684. [PMID: 38132268 PMCID: PMC10742970 DOI: 10.3390/diagnostics13243684] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/19/2023] [Revised: 12/12/2023] [Accepted: 12/13/2023] [Indexed: 12/23/2023] Open
Abstract
(1) Background: when the pathologist faces histologic slides from colonoscopies in daily practice, given the large number of entities and etiologies under inflammatory bowel conditions, in-depth definition of the histological spectrum and the recommendations of current guidelines are often not enough to conclusively define a diagnostic framework. Histological patterns should be organized hierarchically in flowcharts that consider the correlation with clinical data. We conducted an online survey asking a group of gastroenteropathologists to apply a pattern classification based on the most significant lesions in colitis differential diagnosis: crypt distortion and activity. (2) Methods: digital slides from 20 endoscopy samples were analyzed by twenty pathologists and classified according to the occurrence of crypt distortion (nondestructive-destructive colitis) and subsequently to the evidence of activity (ND1-2-3, D1-2). (3) Results: in 8 out of 20 (40%) cases, the participants reached a full agreement regarding the evaluation of crypt distortion (5 cases: nondestructive colitis; 3 cases: destructive colitis). The calculated agreement was k = 0.432. In the second-level quiz (ND1-2-3 and D1-2), full agreement between participants was achieved for 7 of the 28 (25%) possible classifications, with k = 0.229. (4) Conclusions: The findings from this survey are indicative of an unexpectedly low consensus, even among dedicated pathologists, about the recognition of histological changes that are commonly considered critical lesions in the histologic identification of bowel non-neoplastic diseases. In our opinion, these divergences imply a significant risk of misdiagnosis of bowel inflammatory conditions, hampering the usefulness of histological assessment.

Abstract
BACKGROUND Patients with chronic hepatitis C (CHC) and concomitant type 2 diabetes mellitus (DM) show a higher risk of developing hepatocellular carcinoma (HCC). Successful antiviral therapy has reduced the incidence of post-therapy HCC, but the presence of DM still represents an unfavourable predictive factor even in cured patients. Metformin (MET) is recommended as a first-line therapy for DM, and its use is associated with a significant reduction in HCC among diabetic patients with chronic liver disease of different etiology, but very few studies specifically address this issue in patients with CHC. AIM the aim of this review is to evaluate whether the use of MET induces a significant decrease in HCC in diabetic patients with CHC, treated or untreated with antiviral therapy. METHODS A search of PubMed, Medline, Web of Sciences and Embase was conducted for publications evaluating the role of MET in reducing the risk of HCC in patients with DM and CHC, with no language and study type restrictions up to 30 June 2023. Only studies fulfilling the following inclusion criteria were considered: (1) data on the incidence of HCC in the follow-up of diabetic patients with CHC only; (2) follow-up ≥24 months; (3) sufficient data to establish the rate of diabetic patients with CHC treated with metformin or other antidiabetic medications; and (4) data on the type of antiviral treatment and the clinical outcome. RESULTS Three studies met the inclusion criteria. A prospective cohort study considering only patients with DM and untreated advanced CHC, or non-responders to interferon (IFN) therapy, showed that the use of MET was associated with a significant decrease in HCC incidence, liver-related death and liver transplants. A recent retrospective study focusing on a large-scale nationwide cohort of patients with CHC in Taiwan successfully treated with IFN-based therapy stratified patients into 3 groups: non-MET users, MET users and non-diabetic patients, with 5-year cumulative rates of HCC of 10.9%, 2.6% and 3.0%, respectively, showing a significantly higher HCC risk in non-MET users compared with MET users and with non-diabetic patients, while it was not significantly different between MET users and non-diabetic patients. In a recent Italian cohort study focusing on 7007 patients with CHC treated and cured with direct-acting antiviral agents (DAAs), a combined effect of DM and MET therapy was found, showing a higher incidence of HCC in diabetic patients not taking MET compared with those without DM and those with DM taking MET. CONCLUSION according to the current evidence, the use of MET should be encouraged in diabetic patients with CHC in order to reduce the risk of HCC; however, a well-designed randomized controlled trial is needed to establish the generalizability of the beneficial effects of MET in this particular subset of patients.

Impact of PNPLA3 rs738409 Polymorphism on the Development of Liver-Related Events in Patients With Nonalcoholic Fatty Liver Disease. Clin Gastroenterol Hepatol 2023; 21:3314-3321.e3. [PMID: 37149016 DOI: 10.1016/j.cgh.2023.04.024] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/27/2022] [Revised: 04/12/2023] [Accepted: 04/20/2023] [Indexed: 05/08/2023]
Abstract
BACKGROUND AND AIMS Nonalcoholic fatty liver disease (NAFLD) is a complex disease, resulting from the interplay between environmental determinants and genetic variations. Single nucleotide polymorphism rs738409 C>G in the PNPLA3 gene is associated with hepatic fibrosis and with higher risk of developing hepatocellular carcinoma. Here, we analyzed a longitudinal cohort of biopsy-proven NAFLD subjects with the aim to identify individuals in whom genetics may have a stronger impact on disease progression. METHODS We retrospectively analyzed 756 consecutive, prospectively enrolled biopsy-proven NAFLD subjects from Italy, United Kingdom, and Spain who were followed for a median of 84 months (interquartile range, 65-109 months). We stratified the study cohort according to sex, body mass index (BMI) ≥30 kg/m2) and age (≥50 years). Liver-related events (hepatic decompensation, hepatic encephalopathy, esophageal variceal bleeding, and hepatocellular carcinoma) were recorded during the follow-up and the log-rank test was used to compare groups. RESULTS Overall, the median age was 48 years and most individuals were men (64.7%). The PNPLA3 rs738409 genotype was CC in 235 (31.1%), CG in 328 (43.4%), and GG in 193 (25.5%) patients. At univariate analysis, the PNPLA3 GG risk genotype was associated with female sex and inversely related to BMI (odds ratio, 1.6; 95% confidence interval, 1.1-2.2; P = .006; and odds ratio, 0.97; 95% confidence interval, 0.94-0.99; P = .043, respectively). Specifically, PNPLA3 GG risk homozygosis was more prevalent in female vs male individuals (31.5% vs 22.3%; P = .006) and in nonobese compared with obese NAFLD subjects (50.0% vs 44.2%; P = .011). Following stratification for age, sex, and BMI, we observed an increased incidence of liver-related events in the subgroup of nonobese women older than 50 years of age carrying the PNPLA3 GG risk genotype (log-rank test, P = .0047). CONCLUSIONS Nonobese female patients with NAFLD 50 years of age and older, and carrying the PNPLA3 GG risk genotype, are at higher risk of developing liver-related events compared with those with the wild-type allele (CC/CG). This finding may have implications in clinical practice for risk stratification and personalized medicine.

Inflammatory Bowel Disease and Irritable Bowel Syndrome: What Differences in Mentalization Abilities? A Scoping Review. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2023; 20:7125. [PMID: 38063555 PMCID: PMC10706729 DOI: 10.3390/ijerph20237125] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 10/20/2023] [Revised: 11/24/2023] [Accepted: 11/28/2023] [Indexed: 12/18/2023]
Abstract
Mentalization is a psychological process that enables individuals to understand the self and others in terms of intentional mental states. The aim of this scoping review was to provide an overview of the findings on mentalization in patients with inflammatory bowel disease (IBD) and irritable bowel syndrome (IBS). A literature search, in line with the Preferred Reporting Items for Systematic Review and Meta-analysis Protocols extension for Scoping Review guidelines, was conducted in the following bibliographic databases: PubMed, PsycINFO, and Scopus. Databases were queried using the following strings (with Boolean operators): ("mentaliz*" OR "metacogniti*" OR "theory of mind" OR "ToM" OR "reflective function*") AND ("irritable bowel syndrome" OR "IBS" OR "inflammatory bowel disease" OR "IBD"). In line with the eligibility criteria, seven articles were included. Results showed that no significant differences in metacognitive ability were found between patients in the IBD and IBS groups. This review revealed the mentalizing difficulties for patients with IBD and IBS. These results should be interpreted with caution since they are based on a few studies that used different instruments to assess mentalizing processes. Future studies are needed to clarify the role of mentalization in patients with these gastrointestinal conditions.

Abstract
BACKGROUND Autoimmune pancreatitis [AIP] is rarely associated with inflammatory bowel disease [IBD]. The long-term outcomes of AIP and IBD in patients with coexisting AIP-IBD and predictors of complicated AIP course have rarely been reported. METHODS An ECCO COllaborative Network For Exceptionally Rare case reports project [ECCO-CONFER] collected cases of AIP diagnosed in patients with IBD. Complicated AIP was defined as a composite of endocrine and/or exocrine pancreatic insufficiency, and/or pancreatic cancer. We explored factors associated with complicated AIP in IBD. RESULTS We included 96 patients [53% males, 79% ulcerative colitis, 72% type 2 AIP, age at AIP diagnosis 35 ± 16 years]. The majority of Crohn's disease [CD] cases [78%] had colonic/ileocolonic involvement. In 59%, IBD preceded AIP diagnosis, whereas 18% were diagnosed simultaneously. Advanced therapy to control IBD was used in 61% and 17% underwent IBD-related surgery. In total, 82% of patients were treated with steroids for AIP, the majority of whom [91%] responded to a single course of treatment. During a mean follow-up of 7 years, AIP complications occurred in 25/96 [26%] individuals. In a multivariate model, older age at AIP diagnosis was associated with a complicated AIP course (odds ratio [OR] = 1.05, p = 0.008), whereas family history of IBD [OR = 0.1, p = 0.03], and CD diagnosis [OR = 0.2, p = 0.04] decreased the risk of AIP complications. No IBD- or AIP-related deaths occurred. CONCLUSIONS In this large international cohort of patients with concomitant AIP-IBD, most patients have type 2 AIP and colonic IBD. AIP course is relatively benign and long-term outcomes are favourable, but one-quarter develop pancreatic complications. Age, familial history of IBD, and CD may predict uncomplicated AIP course.

Abstract
BACKGROUND AND AIMS Data regarding effectiveness and safety of JAK inhibitors and S1P receptor modulators in antibiotic refractory chronic pouchitis (CARP) are lacking. METHODS This ECCO-CONFER project retrospectively collected JAK inhibitors or S1P receptor modulators treatments for CARP with at least 3-months follow up. The outcomes included corticosteroid and antibiotics-free clinical response and remission at three and twelve months, trend in mPDAI, endoscopic PDAI, CRP and calprotectin. RESULTS Seventeen treatments in 15 patients were collected. Previous pouchitis treatments included infliximab (5/15), adalimumab (4/15), vedolizumab (9/15), and ustekinumab (5/15). Pooling data on JAK inhibitors (8 tofacitinib, 1 filgotinib and 6 upadacitinib), after 3 months (T3), steroid and antibiotics-free clinical response was achieved in 53.3% (8/15), steroid and antibiotics-free clinical remission was achieved in 40% (6/15). Of the patients with at least 12 months of follow-up, steroid and antibiotics-free clinical response was achieved in 50% (3/6) and remission in one patient (16.7%), endoscopic response in 50% (3/6), endoscopic remission in 50% (3/6). Of the two ozanimod treatments at T3, steroid and antibiotics-free clinical response was achieved in one patient, without remission; both discontinued ozanimod before T12. No side effects reported. CONCLUSIONS Small molecules may represent a suitable option for CARP refractory to multiple biologics, deserving further investigation.

The Gum-Gut Axis: Periodontitis and the Risk of Gastrointestinal Cancers. Cancers (Basel) 2023; 15:4594.

Abstract
Periodontitis has been linked to an increased risk of various chronic non-communicable diseases, including gastrointestinal cancers. Indeed, dysbiosis of the oral microbiome and immune-inflammatory pathways related to periodontitis may impact the pathophysiology of the gastrointestinal tract and its accessory organs through the so-called "gum-gut axis". In addition to the hematogenous spread of periodontal pathogens and inflammatory cytokines, recent research suggests that oral pathobionts may translocate to the gastrointestinal tract through saliva, possibly impacting neoplastic processes in the gastrointestinal, liver, and pancreatic systems. The exact mechanisms by which oral pathogens contribute to the development of digestive tract cancers are not fully understood but may involve dysbiosis of the gut microbiome, chronic inflammation, and immune modulation/evasion, mainly through the interaction with T-helper and monocytic cells. Specifically, keystone periodontal pathogens, including Porphyromonas gingivalis and Fusobacterium nucleatum, are known to interact with the molecular hallmarks of gastrointestinal cancers, inducing genomic mutations, and promote a permissive immune microenvironment by impairing anti-tumor checkpoints. The evidence gathered here suggests a possible role of periodontitis and oral dysbiosis in the carcinogenesis of the enteral tract. The "gum-gut axis" may therefore represent a promising target for the development of strategies for the prevention and treatment of gastrointestinal cancers.

Abstract
Inflammatory bowel disease (IBD) is a term used to represent a group of chronic, relapsing inflammatory disorders of the gastrointestinal tract. Crohn's disease (CD) and ulcerative colitis (UC) are the two major clinical forms. The global incidence and prevalence of IBD have increased over the last 2-4 decades. Despite the specific etiopathogenesis of IBD still being unknown, it is widely recognized that immunological, genetic, and environmental factors are implicated. A greater understanding of the multiple signaling pathways involved has led to the development of biologic therapies in the last two decades. Although these treatments have dramatically transformed the course of IBD, there is not a definitive cure and available therapies may cause adverse events (AEs), limiting their use, or have an inadequate effect in some patients. In this context, emerging therapies addressing new specific pathogenetic mechanisms have shown promising efficacy and safety data in early clinical trials. The purpose of this review is to highlight the available clinical trial data for these new drugs, such as more preferential JAK inhibitors, anti-IL-23 antibodies, sphingosine-1-phosphate receptor modulators, anti-integrin therapies, and other small molecules that are currently under research. We will emphasize the potential significance of these agents in shaping future treatment options.

Abstract
BACKGROUND Inflammatory bowel disease (IBD) is a group of chronic multifactorial inflammatory disorders including two major entities: Crohn's disease (CD) and ulcerative colitis (UC). Preliminary evidence suggests that patients with IBD may be at increased risk of developing intestinal and extraintestinal cancers (EICs). Actually, little is known about the association between IBD and EICs, and there is ever-growing concern regarding the safety of immunomodulators and biological therapy, which may represent a risk factor for carcinogenesis. AIMS The aim of this review is to summarize the evidence regarding the association between IBD and EICs, the safety of immunomodulators and biological therapy and the management of immunomodulators and biologic agents in IBD patients with prior or current EICs. RESULTS IBD patients have a higher risk of developing different forms of extraintestinal solid organ tumors and hematological malignancies. Immunomodulators and biological therapy may increase the risk of developing some types of EICs and may be consciously used in patients with IBD and current or prior history of malignancy. CONCLUSIONS Decisions regarding the use of immunomodulators or biological therapies should be made on an individual basis, considering a multidisciplinary approach involving oncologists.

Abstract
Oxidative stress causes several pathological conditions in humans and animals, including gastrointestinal disorders. The aim of this study was to analyze the antioxidant capacity of three natural powdered raw materials containing quercetin, bromelain, and Lentinula edodes and develop a new feed supplement for dogs using a combination of them. The total phenolic content (TPC), antioxidant activity, DPPH (2,2-diphenyl-1-picrylhydrazyl), and ABTS (2,2'-Azino-bis (3-ethylbenzothiazoline-6-sulfonic acid) diammonium salt) of the extracts, either individually or in combination, were evaluated colorimetrically. The effects of this supplement on healthy adult dogs' nutritional, inflammatory, and stress status were evaluated. American Staffordshire Terrier adult female dogs (n = 30) were randomly assigned to a control (n = 15) or a treated (n = 15) group. The supplement was added as powder to the food of the treated dogs once daily for 28 days. There was no significant difference in the body weight and body condition scores between the initial and final phases of the experiment. At the end of our study, a significant decrease in fecal calprotectin, cortisol, indole/skatole, and N-methylhistamine and a significant increase in short-chain fatty acids were observed as compared to the control group. In conclusion, this natural feed supplement can be used to improve gastrointestinal health and psycho-physical conditions in dogs.

Abstract
The study of intestinal permeability is gaining growing interest due to its relevance in the onset and progression of several gastrointestinal and non-gastrointestinal diseases. Though the involvement of impaired intestinal permeability in the pathophysiology of such diseases is recognized, there is currently a need to identify non-invasive biomarkers or tools that are able to accurately detect alterations in intestinal barrier integrity. On the one hand, promising results have been reported for novel in vivo methods based on paracellular probes, i.e., methods that can directly assess paracellular permeability and, on the other hand, on fecal and circulating biomarkers able to indirectly assess epithelial barrier integrity and functionality. In this review, we aimed to summarize the current knowledge on the intestinal barrier and epithelial transport pathways and to provide an overview of the methods already available or currently under investigation for the measurement of intestinal permeability.

Abstract
AIMS Patients with inflammatory bowel disease (IBD) are known to be at increased risk for venous thrombosis, while their risk for arterial ischemic events is debated. The purpose of this study was to conduct a systematic review of the published literature on the risk of myocardial infarction (MI) in IBD patients and to identify any potential risk factors. METHODS The present study was performed according to PRISMA, with a systematic search on PubMed, Cochrane, and Google Scholar. Risk of MI was the primary end point, while all causes of death and stroke were secondary endpoints. Both univariate and multivariate pooled analysis were performed. RESULTS An overall population of 515,455 controls and 77,140 persons with IBD (26,852, 34.8% Crohn's disease, CD and 50,288, 65.2% ulcerative colitis, UC) was included. Mean age was similar across controls and IBD. Persons with CD and UC had lower rates of hypertension (14.5% vs. 14.6% vs. 25%), diabetes (2.9% vs. 5.2% vs. 9.2%) and dyslipidaemia (3.3% vs. 6.5% vs. 16.1%) compared to controls. Smoking did not significantly differ (17% vs. 17.5% vs. 10.6%). Pooled results of multivariate adjustment showed that, after a 5 years-follow-up, both CD and UC were at increased risk of MI (respectively HR 1.36 [1.12-1.64] and HR 1.24 [1.05-1.46]), of death (HR 1.55 [1.27-1.90] and HR 1.29 [1.01-1.64]), and of other CV disease as stroke (HR 1.22 [1.01-1.49] and HR 1.09 [1.03-1.15], all 95% CI). CONCLUSIONS Persons with IBD are at increased risk of MI, despite a lower prevalence of the classic risk factors for MI (hypertension, diabetes, dyslipidemia).

Abstract
Tofacitinib is approved for several immune-mediated inflammatory diseases, but safety concerns have recently been raised. We searched PubMed (accessed on 27 February 2023) for original articles regarding tofacitinib's cancer risk when used for rheumatoid arthritis, ulcerative colitis, Crohn's disease, psoriatic arthritis, and ankylosing spondylitis. Of the 2047 initial records, 22 articles describing 26 controlled studies (including 22 randomized controlled trials) were selected. In the comparison between tofacitinib and any control treatment, the relative risk (RR) for any cancer was 1.06 (95% CI, 0.86-1.31; p = 0.95). In separate comparisons between tofacitinib and either a placebo or biological therapy, no difference was found in the overall cancer risk (vs. placebo, RR = 1.04; 95% CI, 0.44-2.48; p = 0.95; vs. biological drugs, RR = 1.06; 95% CI, 0.86-1.31; p = 0.58). When tofacitinib was compared to tumor necrosis factor (TNF) inhibitors, the overall cancer RR was 1.40 (95% CI, 1.06-2.08; p = 0.02). Similarly, significant results were obtained for all cancers, except for non-melanoma skin cancer (RR = 1.47; 95% CI, 1.05-2.06; p = 0.03), and for this skin cancer alone (RR = 1.30; 95% CI, 0.22-5.83; p = 0.88). In conclusion, no difference in the overall cancer risk was found between tofacitinib and either a placebo or biological drugs, while a slightly higher risk was found in patients treated with tofacitinib than anti-TNF agents. Further studies are needed to better define the cancer risk of tofacitinib therapy.

Abstract
BACKGROUND The management of postoperative recurrence (POR) in Crohn's disease (CD) after ileo-colonic resection is a highly debated topic. Prophylactic immunosuppression after surgery is currently recommended in the presence of at least one clinical risk factor. OBJECTIVE Our aim was to determine whether early immunosuppression can be avoided and guided by endoscopy in CD patients with only one risk factor. METHODS CD patients with only one risk factor for POR, including previous intestinal resection, extensive small intestine resection (>50 cm), fistulising phenotype, history of perianal disease, and active smoking, were retrospectively included. Two groups were formed based on whether immunosuppression was started immediately after surgery ("prophylaxis group") or guided by endoscopy ("endoscopy-driven group"). Primary endpoints were rates of any endoscopic recurrence (Rutgeerts ≥ i2a) and severe endoscopic recurrence (i4) within 12 months after surgery. Secondary outcomes were clinical recurrence rates at 6, 12 and 24 months after surgery. RESULTS A total of 195 patients were enroled, of whom 61 (31.3%) received immunoprophylaxis. No differences between immunoprophylaxis and the endoscopy-driven approach were found regarding any endoscopic recurrence (36.1% vs. 45.5%, respectively, p = 0.10) and severe endoscopic recurrence (9.8% vs. 15.7%, respectively, p = 0.15) at the first endoscopic evaluation. Clinical recurrence rates were also not statistically different (p = 0.43, p = 0.09, and p = 0.63 at 6, 12, and 24 months, respectively). CONCLUSIONS In operated CD patients with only one risk factor for POR, immediate immunoprophylaxis does not decrease the rate of early clinical and endoscopic recurrence. Prospective studies are needed to confirm our results.

[PMID: 36980543 PMCID: PMC10046647 DOI: 10.3390/cancers15061659] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/30/2023] [Revised: 02/26/2023] [Accepted: 03/05/2023] [Indexed: 03/12/2023] Open
Abstract
Hepatocellular carcinoma (HCC) represents a relevant disease burden in cirrhotic patients with non-alcoholic fatty liver disease (NAFLD). We aimed to investigate the prognostic value of simple non-invasive tests (NITs) (AAR, APRI, BARD, FIB-4) for the stratification of HCC risk development in a cohort of 122 consecutive cirrhotic individuals with NAFLD. Over a median follow up of 5.9 (3.2–9.3) years, 13 (10.7%) developed HCC. Only FIB-4 was associated with HCC risk (HR = 1.27, 95% CI 1.03–1.58, p = 0.027). After evaluating different established FIB-4 cut-offs, the lowest cut-off of 1.45 allowed the ruling out of a greater number of patients with a minimal risk of HCC than the 1.3 cut-off (23 vs. 18 patients). Conversely, the cumulative incidence of HCC using the highest cut-off of 3.25 (rule in) was distinctly higher than the 2.67 cut-off (19.4% vs. 13.3%). After multivariate Cox regression analysis, these cut-offs were independently associated with HCC after adjusting for sex, BMI and T2DM (HR = 6.40, 95% CI 1.71–24.00, p = 0.006). In conclusion, FIB-4 values of <1.3 and >3.25 could allow for the optimal stratification of long-term HCC risk in cirrhotic individuals with NAFLD.

Periodontitis prevalence and severity in inflammatory bowel disease: A case-control study. J Periodontol 2023; 94:313-322. [PMID: 36111636 DOI: 10.1002/jper.22-0322] [Citation(s) in RCA: 10] [Impact Index Per Article: 10.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/31/2022] [Revised: 09/05/2022] [Accepted: 09/06/2022] [Indexed: 11/06/2022]
Abstract
BACKGROUND Recent evidence is supporting the notion of a microbiological and immunological continuum on the gum-gut axis in health and disease. Therefore, the purpose of this study was to assess the prevalence and risk indicators of periodontitis in patients with Crohn's disease (CD) or ulcerative colitis (UC) compared to age- and sex-matched controls without inflammatory bowel disease (IBD). METHODS A total of 180 IBD (117 CD, 60 UC, 3 IBD-unclassified) and 180 healthy controls were compared for their periodontitis diagnosis (Centers for Disease Control and Prevention/American Academy of Periodontology [CDC/AAP] case definition) and full-mouth periodontal parameters. In addition, explorative logistic regression models were performed. RESULTS Significantly more patients with IBD had moderate/severe periodontitis (85.6% vs. 65.6%, p < 0.001) and severe periodontitis (36.7% vs. 25.6%, p < 0.001) than controls. Differences were higher in the 35-50 and 51-65 age groups, without significant changes between CD and UC. IBD subjects presented chances ∼3.5 higher of having moderate/severe periodontitis (p < 0.001). Significant variables associated with periodontitis in the whole sample were older age, presence of IBD, and higher full-mouth plaque scores, whereas in the IBD group they were male sex, IBD-associated surgery, and IBD duration and localization (pancolitis). Positive risk indicators for IBD were periodontitis severity and higher bleeding scores, while smoking was negatively associated with UC. CONCLUSIONS Relevant associations between IBD and periodontitis were found, being modified by CD and UC clinical characteristics. Preventive and therapeutic strategies involving the gum-gut axis should be enforced in IBD patients.

Abstract
BACKGROUND AND AIMS Solid organ transplantation, with the exception of liver, has rarely been reported in patients affected by inflammatory bowel diseases (IBD). METHODS This is an ECCO-CONFER project collecting cases of solid organ transplants (with the exclusion of liver) that were performed in IBD patients. We evaluated the change in the IBD therapy, need for bowel resection due to medically refractory IBD, or need for hospitalization due to IBD relapse ("severe IBD course") before and after transplantation. RESULTS Thirty-four organ transplantations (28 kidney, five heart, one lung) in 33 IBD patients were collected (67% male; 55% Crohn's disease, mean age 53 ± 16 years). The median follow-up was 4.3 years (IQR 3.2 - 10.7). Twenty-nine patients (87.9%) were treated with tacrolimus, 25 (76%) with systemic steroids, 22 (67%) with mycophenolate mofetil, 11 (33%) with everolimus, six with cyclosporine (18%). One patient was treated with infliximab, two patients with adalimumab, two patients with vedolizumab, one patient with ustekinumab. Overall, a severe IBD course was observed in three (9.3%) patients before transplantation and in four (11.7%) in the post-transplant setting (p = 0.26). Three cases of cancer (excluding skin non-melanoma) (9.1%) were recorded in post-transplantation period versus two in the pre-transplant (6.1%, p = 0.04).Six patients (18.2%) died during the period of observation. No deaths were associated with IBD or complications of the transplant. CONCLUSIONS In IBD patients, solid organ transplantation does not seem to impact on the IBD severity. However, the risk of malignancy needs further investigation.

NAMPT and NAPRT serum levels predict response to anti-TNF therapy in inflammatory bowel disease. Front Med (Lausanne) 2023; 10:1116862. [PMID: 36817780 PMCID: PMC9928959 DOI: 10.3389/fmed.2023.1116862] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/05/2022] [Accepted: 01/17/2023] [Indexed: 02/04/2023] Open
Abstract
Background Nicotinamide phosphoribosyltransferase (NAMPT) and nicotinic acid phosphoribosyl transferase (NAPRT) are key intracellular enzymes that participate in the biosynthesis on NAD but have also been shown to be released as proinflammatory cytokines. A number of reports have shown that circulating NAMPT is increased in serum of patients with inflammatory disorders, including inflammatory bowel diseases (IBD), while nothing is known regarding circulating NAPRT and the presence of both cytokines in IBD patient stools. In the present study, we evaluated eNAMPT and eNAPRT levels in a large cohort of IBD patients not on biological therapy and in a subset that then was prescribed biologics. Methods We conducted a retro-perspective study on 180 patients, of which 111 underwent subsequent biological treatment (adalimumab, vedolizumab, and ustekinumab). We analyzed eNAMPT and eNAPRT concentrations in serum and faces of IBD patients, correlating them with response to biologics. Results We now report that eNAMPT and eNAPRT are significantly increased in both serum and stools of IBD patients. NAMPT and NAPRT levels correlate with disease severity, with C reactive protein and with serum IL-6 levels. Importantly, levels of NAMPT in patients starting treatment with adalimumab correlate with response failure at three months: patients with levels above 4 ng/ml were significantly less likely to obtain benefit. Serum NAMPT as a biomarker of response yields a sensitivity of 91% and a specificity of 100%. Conclusion The present work strongly suggests that a prospective trial evaluating eNAMPT and eNAPRT levels in relation to response to biologicals in IBD should be initiated.

Abstract
Current treatment for celiac disease (CD) is adhering to a gluten-free diet (GFD), although its long-term molecular effects are still undescribed. New molecular features detectable in stool may improve and facilitate noninvasive clinical management of CD. For this purpose, fecal small non-coding RNAs (sncRNAs) and gut microbiome profiles were concomitantly explored in CD subjects in relation to strict (or not) GFD adherence over time. In this observational study, we performed small RNA and shotgun metagenomic sequencing in stool from 63 treated CD (tCD) and 3 untreated subjects as well as 66 sex- and age-matched healthy controls. tCD included 51 individuals on strict GFD and with negative transglutaminase (TG) serology (tCD-TG-) and 12 symptomatic with not strict/short-time of GFD adherence and positive TG serology (tCD-TG+). Samples from additional 40 healthy adult individuals and a cohort of 19 untreated pediatric CD subjects and 19 sex/age matched controls were analyzed to further test the outcomes. Several miRNA and microbial profiles were altered in tCD subjects (adj. p < .05). Findings were validated in the external group of adult controls. In tCD-TG-, GFD duration correlated with five miRNA levels (p < .05): for miR-4533-3p and miR-2681-3p, the longer the diet adherence, the less the expression differed from controls. tCD-TG+ and untreated pediatric CD patients showed a similar miRNA dysregulation. Immune-response, trans-membrane transport and cell death pathways were enriched in targets of identified miRNAs. Bifidobacterium longum, Ruminococcus bicirculans, and Haemophilus parainfluenzae abundances shifted (adj. p < .05) with a progressive reduction of denitrification pathways with GFD length. Integrative analysis highlighted 121 miRNA-bacterial relationships (adj. p < .05). Specific molecular patterns in stool characterize CD subjects, reflecting either the long-term GFD effects or the gut inflammatory status, in case of a not strict/short-time adherence. Our findings suggest novel host-microbial interplays and could help the discovery of biomarkers for GFD monitoring over time.

Possible Impact of Vitamin D Status and Supplementation on SARS-CoV-2 Infection Risk and COVID-19 Symptoms in a Cohort of Patients with Inflammatory Bowel Disease. Nutrients 2022; 15:nu15010169.

Abstract
The coronavirus disease (COVID-19) pandemic represents a global health challenge, particularly considering concomitant diseases. Patients with inflammatory bowel diseases (IBD) can be considered a population at risk. On the other hand, the risk of developing IBD and COVID-19 have both been described as modulated by vitamin D (VD) levels. In this work, a cohort of 106 adult patients affected by IBD was prospectively enrolled, during the second wave of the pandemic in Italy. In these patients, VD plasma levels, demographic, and clinical characteristics were tested for a correlation/an association with the risk of infection with SARS-CoV-2 in the study period (anti-spike IgG positivity) and the severity of COVID-19 symptoms. By multivariate logistic regression analysis, VD supplementation (Odds Ratio; OR 0.116, p = 0.002), therapy with monoclonal antibodies (OR 0.227, p = 0.007), and the use of mesalazine (OR 2.968, p = 0.046) were found to be independent predictors of SARS-CoV-2 positivity. Moreover, hypertension was associated with severe disease (p = 0.019), while a VD level higher than 30 ng/mL (p = 0.031, OR 0.078) was associated with asymptomatic infection. No interplay between IBD activity and COVID-19 risk of infection or symptoms was observed. These results confirm the importance of VD levels in defining the risk of COVID-19 and give encouraging data about the safety of maintaining immunomodulatory treatments for IBD during the COVID-19 pandemic.

Abstract
BACKGROUND Endoscopic-post-operative-recurrence [ePOR] in Crohn's disease [CD] after ileocecal resection [ICR] is a major concern. We aimed to evaluate the effectiveness of early prophylaxis with biologics and to compare anti-tumour necrosis factor [anti-TNF] therapy to vedolizumab [VDZ] and ustekinumab [UST] in a real-world setting. METHODS A retrospective multicentre study of CD-adults after curative ICR on early prophylaxis was undertaken. ePOR was defined as a Rutgeerts score [RS] ≥ i2 or colonic-segmental-SES-CD ≥ 6. Multivariable logistic regression was used to evaluate risk factors, and inverse probability treatment weighting [IPTW] was applied to compare the effectiveness between agents. RESULTS The study included 297 patients (53.9% males, age at diagnosis 24 years [19-32], age at ICR 34 years [26-43], 18.5% smokers, 27.6% biologic-naïve, 65.7% anti-TNF experienced, 28.6% two or more biologics and 17.2% previous surgery). Overall, 224, 39 and 34 patients received anti-TNF, VDZ or UST, respectively. Patients treated with VDZ and UST were more biologic experienced with higher rates of previous surgery. ePOR rates within 1 year were 41.8%. ePOR rates by treatment groups were: anti-TNF 40.2%, VDZ 33% and UST 61.8%. Risk factors for ePOR at 1 year were: past-infliximab (adjusted odds ratio [adj.OR] = 1.73 [95% confidence interval, CI: 1.01-2.97]), past-adalimumab [adj.OR = 2.32 [95% CI: 1.35-4.01] and surgical aspects. After IPTW, the risk of ePOR within 1 year of VDZ vs anti-TNF or UST vs anti-TNF was comparable (OR = 0.55 [95% CI: 0.25-1.19], OR = 1.86 [95% CI: 0.79-4.38]), respectively. CONCLUSION Prevention of ePOR within 1 year after surgery was successful in ~60% of patients. Patients treated with VDZ or UST consisted of a more refractory group. After controlling for confounders, no differences in ePOR risk were seen between anti-TNF prophylaxis and other groups.

Abstract
Zonulin is a novel biomarker of intestinal permeability. The existing data suggest that upregulation of zonulin might be linked to systemic inflammation and pregnancy complications. A systematic search was performed in medical electronic databases to identify eligible studies that reported circulating zonulin levels in complicated pregnancies compared to controls. Eight studies with 1196 serum samples of pregnant women were included in the systematic review. Meta-analysis on four studies revealed a significant increase in serum zonulin in women with Gestational diabetes mellitus (GDM) compared to healthy controls (Cohen's d = 2.06; 95% Confidence Interval (CI): 0.15, 3.98). By pooling four studies that investigated zonulin levels in Hypertensive disorders of pregnancy (HDP), higher zonulin concentrations were found in cases, while the difference was not significant (Cohen's d = 0.86; 95% CI: -0.04, 1.75). Current evidence suggests that higher levels of zonulin during pregnancy seem to be associated with inflammation-related complications, including GDM and HDP.Impact StatementWhat is already known on this subject? Increased zonulin levels are considered as a marker of intestinal hyper-permeability. Upregulation of zonulin and concurrent systemic inflammation, are known to be associated with some pregnancy complications.What do the results of this study add? We performed a meta-analysis to evaluate changes in serum zonulin levels in pregnancies complicated with Gestational diabetes mellitus (GDM), Hypertensive disorders of pregnancy (HDP), and Intrahepatic cholestasis of pregnancy (ICP). According to our results, zonulin levels were significantly higher in complicated pregnancies than in normal pregnancies, particularly for GDM.What are the implications of these findings for clinical practice and/or further research? Our findings revealed a probable association between increased zonulin levels and inflammation-related complications during pregnancy. Moreover, zonulin could serve as a reliable diagnostic clinical biomarker to identify (or predict) complications during pregnancy. Further studies are needed to examine the clinical accuracy of zonulin for detecting pregnancy-related complications.

Abstract
Vagus nerve stimulation (VNS) is an accepted therapy for the treatment of refractory forms of epilepsy and depression. The brain–gut axis is increasingly being studied as a possible etiological factor of chronic inflammatory diseases, including inflammatory bowel diseases (IBD). A significant percentage of IBD patients lose response to treatments or experience side effects. In this perspective, VNS has shown the first efficacy data. The aim of this narrative review is to underline the biological plausibility of the use of VNS in patients affected by IBD, collect all clinical data in the literature, and hypothesize a target IBD population on which to focus the next clinical study.

Abstract
In patients with Crohn’s disease (CD) that underwent surgery, predictive factors of surgical recurrence have been only partially identified. The aim of our study was to identify potential factors associated with an increased risk of surgical recurrence. A monocentric retrospective observational study was conducted including patients diagnosed with CD, according to ECCO criteria who received their first ileocolic resection. Overall, 162 patients were enrolled in our study; 54 of them were excluded due to a lack of sufficient data. The median follow-up was 136.5 months, IQR 91.5−176.5, and the surgical recurrence rate after the median follow-up was 21.3%. In the multivariate analysis, an age ≤ 28 years at the first surgical resection (aHR = 16.44, p < 0.001), current smoking (aHR = 15.84, p < 0.001), female sex (aHR = 7.58, p < 0.001), presence of granulomas at local lymph nodes (aHR = 12.19, p < 0.001), and treatment with systemic corticosteroids after the first surgical resection (aHR = 7.52, p = 0.002) were factors significantly associated with a risk of surgical recurrence, while cryptitis resulted in a protective factor (aHR = 0.02, p < 0.001). In conclusion, the heterogeneous spectrum of factors associated to the risk of surgical recurrence in patients with CD that underwent ileocolic resection supports the need of a personalized follow-up taking into account different clinical, surgical, and histologic features.

Abstract
Reliable non-invasive biomarkers for the surveillance of patients at risk of hepatocellular carcinoma (HCC) development represent an unmet medical need. Recently, the liver-cancer-specific isoform of serine protease inhibitor Kazal (LC-SPIK) has been proposed as a valuable biomarker for the detection of HCC in patients with chronic liver disease of viral etiology. In the present study, we assessed the diagnostic accuracy of LC-SPIK, alone or in combination with standard serologic biomarkers (i.e., alpha-fetoprotein and protein induced by vitamin K absence or antagonist-II, PIVKA-II), for the detection of HCC among patients with dysmetabolic liver disease. A total of 120 patients with non-alcoholic fatty liver disease (NAFLD), including 62 patients with a diagnosis of HCC and 58 with cirrhosis but without tumor, were retrospectively analyzed. The serum levels of LC-SPIK were measured by enzyme-linked immunosorbent assay (ImCare Biotech, Doylestown, PA). The serum LC-SPIK values were significantly different between patients with HCC (24.3, 17.6−39.8 ng/mL) and those with cirrhosis but without tumor (11.7, 8.7−18.2 ng/mL) (p < 0.001). By receiver operating characteristic curve analysis, we observed an area under the curve (AUC) of 0.841 for the detection of HCC; the combination with PIVKA-II further increased the accuracy to AUC = 0.926 (cross-validation). The promising results observed in the present pilot study foster additional research to investigate the usefulness of LC-SPIK for the stratification of the risk of HCC development in patients with NAFLD and advanced liver disease.

Abstract
BACKGROUND Gastroenteropancreatic neuroendocrine neoplasms [GEP-NENs] have rarely been reported in association with inflammatory bowel diseases [IBDs]. METHODS An ECCO COllaborative Network For Exceptionally Rare case reports project [ECCO-CONFER] collects cases of GEP-NENs diagnosed in patients with IBD. RESULTS GEP-NEN was diagnosed in 100 IBD patients; 61% female, 55% Crohn's disease, median age 48 years (interquartile range [IQR] 38-59]). The most common location was the appendix [39%] followed by the colon [22%]. Comprehensive IBD-related data were available for 50 individuals with a median follow-up of 30 months [IQR 11-70] following NEN diagnosis. Median duration of IBD at NEN diagnosis was 84 months [IQR 10-151], and in 18% of cases NEN and IBD were diagnosed concomitantly. At diagnosis, 20/50 were stage-I [T1N0M0], and 28/50 were graded G1 [ki67 ≤2%]. Incidental diagnosis of NEN and concomitantly IBD diagnosis were associated with an earlier NEN stage [p = 0.01 and p = 0.02, respectively]. Exposure to immunomodulatory or biologic therapy was not associated with advanced NEN stage or grade. Primary GEP-NEN were more frequently found in the segment affected by IBD [62% vs 38%]. At the last follow-up data, 47/50 patients were alive, and only two deaths were related to NEN. CONCLUSIONS In the largest case series to date, prognosis of patients with GEP-NEN and IBD seems favourable. Incidental NEN diagnosis correlates with an earlier NEN stage, and IBD-related therapies are probably independent of NEN stage and grade. The association of GEP-NEN location and the segment affected by IBD may suggest a possible role of inflammation in NEN tumorigenesis.

Abstract
BACKGROUND & AIMS limited evidence is available to guide hepatologists regarding endoscopic surveillance of oesophageal varices (EV) in Hepatitis C Virus (HCV)-positive cirrhotic patients achieving a sustained virologic response. To address these issues, we conducted a long-term prospective study on 427 HCV-positive cirrhotic patients successfully treated by Direct Antiviral Agents (DAAs). METHODS Patients were divided into two groups according to their baseline Baveno VI status: Group 1 (92, 21.5%, favourable Baveno VI status) and Group 2 (335, 78.5%, unfavourable Baveno VI status). Each patient underwent baseline endoscopy and was endoscopically monitored for a median follow-up of 65.2 months according to Baveno VI recommendations. RESULTS About 4.3% of Group 1 patients showed baseline EV compared with 30.1% of Group 2 patients (p < .0001). No patients belonging to Group 1 without baseline EV developed EV at follow-up endoscopy compared with 6.5% in Group 2 patients (p = .02); 69/107 (64.5%) patients with baseline EV showed small varices. During the endoscopic follow-up, EV disappeared/improved in 36 (33.6%), were stable in 39 (36.4%) and worsened in 32 (29.9%) patients, all belonging to Group 2 (p = .001). Improvement in Baveno VI status was observed in 118/335 (35.2%, p < .0001) of Group 2 patients and among those without pre-therapy EV, none developed EV throughout the follow-up. CONCLUSIONS HCV-positive cirrhotic patients cured by DAAs showing baseline favourable Baveno VI status and no worsening during follow-up can safely avoid endoscopic screening and surveillance. Patients having unfavourable Baveno VI status without baseline EV who improve their status may suspend further endoscopic surveillance.

Abstract
BACKGROUND There is a small but measurable increased risk of lymphoma in inflammatory bowel disease [IBD], with a suggestion that primary intestinal lymphoma [PIL] in IBD is associated with inflamed tissue and immunosuppressant use, mainly thiopurines. METHODS This multicentre case series was supported by the European Crohn's and Colitis Organisation [ECCO] and performed as part of the Collaborative Network of Exceptionally Rare case reports [CONFER] project. Clinical data were recorded in a standardized case report form. RESULTS Fifteen patients with intestinal lymphoma from eight centres were included (12 males, 11 patients with Crohn's disease [CD], mean age 47.8 [±16.4 SD, range 26-76] years at lymphoma diagnosis). Lymphoma type was diffuse large B-cell lymphoma [DLBCL] in eight, Hodgkin's disease in two, mucosa-associated lymphoid tissue [MALT] lymphoma in three, and single cases of immunoblastic lymphoma and indolent T-cell lymphoma. Lymphoma was located within the IBD-affected area in ten patients. At lymphoma diagnosis, nine patients had a history of azathioprine or anti-tumour necrosis factor [TNF] use. Lymphoma was diagnosed at a mean time of 10.4 [±7.07, 1-24] years after IBD diagnosis in 11 patients, prior to IBD in two and concurrently in two. Sustained remission over a median follow-up time of 6.5 [1.5-20] years was achieved in ten patients after treatment; five of them had started biological therapy [including anti-TNFs, vedolizumab and ustekinumab] for active CD subsequent to their PIL treatment. CONCLUSION In this small case series, two-thirds of patients developed lymphoma in the IBD-affected area, and almost two-thirds had a history of thiopurine or anti-TNF use. Biologics were restarted without recurrence of lymphoma in half of the remitters.

Effectiveness of adalimumab for ulcerative colitis: A multicentre, retrospective study of clinical practice in Italy. Dig Liver Dis 2022; 54:352-357. [PMID: 34538764 DOI: 10.1016/j.dld.2021.08.020] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/05/2021] [Revised: 08/12/2021] [Accepted: 08/25/2021] [Indexed: 12/11/2022]
Abstract
BACKGROUND Adalimumab is used to treat ulcerative colitis, but additional effectiveness and safety data are needed. PATIENTS AND METHODS This retrospective study considered adults with ulcerative colitis treated with adalimumab at 19 hospitals. Clinical data were collected from the start of treatment, after 2, 6 and 12 months, and at the last visit. Outcome measures of effectiveness were treatment duration, reasons for discontinuation and colectomy. RESULTS We studied 381 patients treated with adalimumab for a median of 12.1 months. Disease activity at the start of treatment was moderate to severe in 262 cases (68.8%) and endoscopic activity was moderate to severe in 339 cases (89.0%). At week 8, clinical responses were observed in 177 cases (46.5%) and clinical remission in 136 cases (35.7%). At 12 months, remission was observed in 128 cases (33.6%). Overall, 44 patients required colectomy, and 170 patients (44.6%) were still taking adalimumab when data were collected. Variables associated with adalimumab discontinuation were concomitant steroid treatment, severe clinical-endoscopic activity at baseline, need for adalimumab intensification and drug-related adverse events. Variables associated with colectomy were concomitant steroid treatment and high baseline C-reactive protein. CONCLUSION Adalimumab is safe and effective for the treatment of ulcerative colitis.

Effect of COVID-19 Pandemic on Hepatocellular Carcinoma Diagnosis: Results from a Tertiary Care Center in North-West Italy. Curr Oncol 2022; 29:1422-1429. [PMID: 35323319 PMCID: PMC8946861 DOI: 10.3390/curroncol29030119] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/20/2022] [Revised: 02/17/2022] [Accepted: 02/23/2022] [Indexed: 12/23/2022] Open
Abstract
The COVID-19 pandemic has forced us to direct most of the available resources towards its management. This has led to the neglect of all other pathologies, including cancer. The aim of this study was to verify whether the difficulty in accessing the health system has led to a reduction in new diagnoses of hepatocellular carcinoma (HCC) and whether this has already been reflected in a more advanced stage of the cancer. A single-center, retrospective study including adult patients with a new diagnosis of HCC was performed. Patients were divided into three groups: the prelockdown phase (May 2019–February 2020), the lockdown phase (March 2020–December 2020), and the postlockdown phase (January 2021–October 2021); 247 patients were included. The number of patients diagnosed with HCC distinctly diminished in the periods March 2020–December 2020 (n = 69; −35%) and January 2021–October 2021 (n = 72; −32%) as compared to the period May 2019–February 2020 (n = 106). Noteworthy was the reduced surveillance in the period January 2021–October 2021 as compared to May 2019–February 2020 (22.9% vs. 36.6%, p = 0.056). No significant changes have yet been observed in tumor characteristics (BCLC staging distribution remained unvaried, p = 0.665). In conclusion, the number of new HCC diagnoses decreased sharply in the first 2 years of the pandemic, with no worsening of the stage. A more advanced stage of the disease could be expected in the next few years in patients who have escaped diagnosis.

Impact of Macroscopic On-Site Evaluation (MOSE) on Accuracy of Endoscopic Ultrasound-Guided Fine-Needle Biopsy (EUS-FNB) of Pancreatic and Extrapancreatic Solid Lesions: A Prospective Study. Diagnostics (Basel) 2022; 12:diagnostics12020428. [PMID: 35204519 PMCID: PMC8870967 DOI: 10.3390/diagnostics12020428] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/30/2021] [Revised: 01/24/2022] [Accepted: 02/04/2022] [Indexed: 11/16/2022] Open
Abstract
This is a prospective and comparative study including 76 consecutive patients performing EUS-FNB for pancreatic and extrapancreatic solid lesions, randomized by alternate allocation to macroscopic on-site evaluation (MOSE) (40 patients) or to a conventional technique (40 patients), with three passes each. MOSE samples were differentiated into score 0: no visible material, score 1: only necrotic or haematic material, score 2: white core tissue ≤ 2 mm, or score 3: white core tissue > 2 mm. The conventional technique consisted in pushing all the needle content into a test tube for evaluation by the pathologist. In both groups, a 22–25 Gauge Franseen-tip needle (Acquire, Boston Scientific Co., Natick, MA, USA) was used. The study evaluated the diagnostic accuracy and adequacy of MOSE compared to the conventional technique and whether MOSE could optimize the number of passes during EUS-FNB. Results: The analysis was performed on 76 patients (38 MOSE, 38 conventional). The overall diagnostic adequacy was 94.7% (72/76) and accuracy was 84.2% (64/76). The diagnostic accuracy was similar in the two groups: MOSE 86.8% (33/38 lesions), vs. conventional 81.6%, 31/38 lesions, p = 0.76). Regarding diagnostic adequacy, the MOSE technique was 97.4% (111/114 passes) compared to 92.1% (105/114 passes) with the conventional technique, p = 0.06. The accuracy increased according to the MOSE score evaluation: it was 43.5%, 65.5% and 78.3% in patients with score 1, score 2, and score 3, respectively. Moreover, if in the first two passes the MOSE score was 2 or 3, the accuracy was 82.6% (20/23), and upon adding a third pass, the accuracy increased to 87% (20/23), which was not significantly different from the general accuracy of the MOSE samples (86.8%) (p = 0.86). Conclusions: The MOSE score showed a comparable diagnostic accuracy to the conventional technique. However, MOSE allows endoscopists to perform an inspective evaluation of the material, tends to perform better than the conventional technique in terms of diagnostic adequacy, and may potentially reduce the number of passes.

Primary Hypogammaglobulinaemia with Inflammatory Bowel Disease-Like Features: An ECCO CONFER Multicentre Case Series. J Crohns Colitis 2022; 16:91-97. [PMID: 34274962 DOI: 10.1093/ecco-jcc/jjab124] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Indexed: 01/16/2023]
Abstract
BACKGROUND Hypogammaglobulinaemia is a disorder characterized by low serum immunoglobulin levels and a high prevalence of gastrointestinal manifestations. In some cases, clinical and endoscopic features are indistinguishable from those of inflammatory bowel disease [IBD]. METHODS This was a multicentre case series performed as a part of the European Crohn's and Colitis Organisation [ECCO] Collaborative Network of Exceptionally Rare case reports [CONFER] project. RESULTS This report includes 27 patients with primary hypogammaglobulinaemia and IBD-like features: 20 males and seven females, median age 45.6 years (interquartile range [IQR] 35.2-59). Crohn's disease-like features were noted in 23 patients, and four patients had ulcerative colitis-like features. The diagnosis of hypogammaglobulinaemia preceded a diagnosis of IBD-like features in 20 patients [median of 7 years prior, IQR 2.6-20.6 years], and followed the appearance of IBD-like features in seven cases [median of 1 year after, IQR 0.45-5.6 years]. Hypogammaglobulinaemia aetiologies were common variable immunodeficiency [66.6%], agammaglobulinaemia [7.4%], selective IgA-deficiency [11.1%], Good's syndrome [7.4%], IgG subclass deficiency with IgA deficiency [3.7%] and hyper-IgM [3.7%]. In addition to antibiotics and intravenous immunoglobulin [IVIG] for hypogammaglobulinaemia, 12 patients received IBD-related treatment including 5-aminosalicylate agents [two patients], corticosteroids [one patient], thiopurines [three patients], anti-tumour necrosis factor [four patients] and vedolizumab [two patients]. By the end of the follow-up (44.5 months [IQR 18-81]), 21/27 [77%] patients were in clinical remission. CONCLUSION This case series describes IBD-like features in patients with hypogammaglobulinaemia. The diagnosis of IBD-like features mainly occurred after that of hypogammaglobulinaemia, with successful recovery in the majority of cases after appropriate treatment.

Therapies for inflammatory bowel disease do not pose additional risks for adverse outcomes of SARS-CoV-2 infection: an IG-IBD study. Aliment Pharmacol Ther 2021; 54:1432-1441. [PMID: 34694009 PMCID: PMC8653024 DOI: 10.1111/apt.16663] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/03/2021] [Revised: 09/10/2021] [Accepted: 10/07/2021] [Indexed: 02/06/2023]
Abstract
BACKGROUND Older age and comorbidities are the main risk factors for adverse COVID-19 outcomes in patients with inflammatory bowel disease (IBD). The impact of IBD medications is still under investigation. AIMS To assess risk factors for adverse outcomes of COVID-19 in IBD patients and use the identified risk factors to build risk indices. METHODS Observational cohort study. Univariable and multivariable logistic regression was used to identify risk factors associated with pneumonia, hospitalisation, need for ventilatory support, and death. RESULTS Of the 937 patients (446 with ulcerative colitis [UC]) evaluated, 128 (13.7%) had asymptomatic SARS-CoV-2 infection, 664 (70.8%) had a favourable course, and 135 (15.5%) had moderate or severe COVID-19. In UC patients, obesity, active disease and comorbidities were significantly associated with adverse outcomes. In patients with Crohn's disease (CD), age, obesity, comorbidities and an additional immune-mediated inflammatory disease were identified as risk factors. These risk factors were incorporated into two indices to identify patients with UC or CD with a higher risk of adverse COVID-19 outcomes. In multivariable analyses, no single IBD medication was associated with poor COVID-19 outcomes, but anti-TNF agents were associated with a lower risk of pneumonia in UC, and lower risks of hospitalisation and severe COVID-19 in CD. CONCLUSION The course of COVID-19 in patients with IBD is similar to that in the general population. IBD patients with active disease and comorbidities are at greater risk of adverse COVID-19 outcomes. IBD medications do not pose additional risks. The risk indices may help to identify patients who should be prioritised for COVID-19 re-vaccination or for therapies for SARS-CoV-2 infection.
