RESUMO
Therapeutic targets in Crohn's disease (CD) have evolved greatly over the past several decades to include endoscopic improvement along with clinical remission. Yet CD is characterized by transmural damage, and there is increasing evidence of improved outcomes associated with transmural healing. Intestinal ultrasonography is a noninvasive, highly accurate imaging modality that provides real-time results and can assess for transmural healing in CD. In this review, we present the definition of transmural healing by ultrasonography, its comparison with other imaging modalities and with endoscopy, the efficacy of diverse therapies on achieving transmural healing, and data on patient outcomes in those achieving transmural healing. This review can guide clinicians who care for patients with inflammatory bowel disease on the added value of achieving transmural healing and its eventual incorporation as a target of therapy.

INTRODUCTION: Inflammatory bowel disease (IBD) and endometriosis are chronic inflammatory diseases occurring in young women, sharing some clinical manifestations. In a multidisciplinary approach, we aimed to investigate symptoms, type, and site of pelvic endometriosis in IBD patients versus non-IBD controls with endometriosis. METHODS: In a prospective nested case-control study, all female premenopausal IBD patients showing symptoms compatible with endometriosis were enrolled. Patients were referred to dedicated gynecologists for assessing pelvic endometriosis by transvaginal sonography (TVS). Each IBD patient with endometriosis (cases) was retrospectively matched for age (±5 years) and body mass index (±1) with 4 patients with endometriosis at TVS but no-IBD (controls). Data were expressed as median [range]; the Mann-Whitney or Student t and χ2 tests were used for comparisons. RESULTS: Endometriosis was diagnosed in 25 (71%) out of 35 IBD patients with compatible symptoms including 12 (52.6%) Crohn's disease and 13 (47.4%) ulcerative colitis patients. Dyspareunia and dyschezia were significantly more frequent in cases versus controls (25 [73.7%] vs. 26 [45.6%]; p = 0.03). At TVS, deep infiltrating endometriosis (DIE) and posterior adenomyosis were significantly more frequently observed in cases versus controls (25 [100%] vs. 80 [80%]; p = 0.03 and 19 [76%] vs. 48 [48%]; p = 0.02). CONCLUSIONS: Endometriosis was detected in two-thirds of IBD patients with compatible symptoms. The frequency of DIE and posterior adenomyosis was higher in IBD than in controls. A diagnosis of endometriosis, often mimicking IBD activity, should be considered in subgroups of female patients with IBD.

BACKGROUND & AIMS: Bowel ultrasonography (BUS) is a noninvasive tool for evaluating bowel activity in Crohn's disease (CD) patients. Aim of our multicenter study was to assess whether BUS helps to monitor intestinal activity improvement/resolution following different biological therapies. METHODS: Adult CD patients were prospectively enrolled at 16 sites in Italy. Changes in BUS parameters [i.e. bowel wall thickening (BWT), lesion length, echo pattern, blood flow changes and transmural healing (TH: normalization of all BUS parameters)] were analyzed at baseline and after 3, 6 and 12 months of different biological therapies. RESULTS: One hundred eighty-eight out of 201 CD patients were enrolled and analyzed (116 males [62%]; median age 36 years). Fifty-five percent of patients were treated with adalimumab, 16% with infliximab, 13% with vedolizumab and 16% with ustekinumab. TH rates at 12 months were 27.5% with an NNT of 3.6. TH at 12 months after adalimumab was 26.8%, 37% after infliximab, 27.2% after vedolizumab and 20% after ustekinumab. Mean BWT improvement from baseline was statistically significant at 3 and 12 months (P < .0001). Median Harvey-Bradshaw index, C-reactive protein and fecal calprotectin decreased after 12 months from baseline (P < .0001). Logistic regression analysis showed colonic lesion was associated with a higher risk of TH at 3 months and a greater BWT at baseline was associated with a lower risk of TH at 3 months [P = .03 (OR 0.70, 95% CI 0.50-0.97)] and 12 months [P = .01 (OR 0.58, 95% CI 0.38-0.89)]. At 3 months therapy optimization during the study was the only independent factor associated with a higher risk of no ultrasonographic response [P = .02 (OR 3.34, 95% CI 1.18-9.47)] and at 12 months disease duration [P = .02 (OR 3.03, 95% CI 1.15-7.94)]. CONCLUSIONS: Data indicate that BUS is useful to monitor biologics-induced bowel activity improvement/resolution in CD.

BACKGROUND & AIMS: Mucosal healing, determined by ileocolonoscopy, is a goal for treatment of Crohn's disease (CD), but this is an invasive assessment procedure. We investigated whether response to tumor necrosis factor (TNF) antagonists, determined by small-intestine contrast ultrasonography, associates with long-term outcomes. METHODS: We performed observational study of 80 patients with CD treated with anti-TNF agents for at least 1 year who underwent serial small intestine contrast ultrasonography (SICUS) at the University of Rome, in Italy. SICUS was used to evaluate disease site (based on bowel wall thickness), extent of lesions, and presence of complications. Inclusion criteria required pre-therapy SICUS with follow-up SICUS after 18 months. At second SICUS, patients were assigned to categories of complete or partial responder or non-responder. CD-related outcomes (corticosteroid need, hospitalization, and surgery) were assessed at 1 year from the second SICUS, using multivariate models, and were analyzed after long term follow up (5 years) using Kaplan-Meier survival analysis. RESULTS: Based on SICUS, after a median of 18 months, 36 patients (51%) were complete responders, 30 were partial responders (34%), and 13 were non-responders (15%). At 1 year from the second SICUS, no patients with a complete response, based on ultrasonography, underwent surgery, in comparison to partial responders (P = .0003) or non-responders (P = .001). Complete responders used smaller amounts of corticosteroids than partial responders (P = .0001) or non-responders (P < .0001). Complete responders required fewer hospitalizations than non-responders (P = .001). Kaplan-Meier survival analysis of long-term follow up data demonstrated a lower cumulative probability of need for surgery, hospitalization, and need for steroids among SICUS-categorized complete responders (P < .0001, P = .003 and P = .0001 respectively) than SICUS-categorized non-responders. CONCLUSIONS: In patients with CD, response to anti-TNF agents, determined by SICUS, is associated with better long-term outcomes than partial or no response. Ultrasonographic assessment therefore provides a relatively non-invasive method for monitoring response to treatment in patients with CD.

BACKGROUND: In Crohn's disease (CD), one of the major inflammatory bowel disease (IBD) in human beings, there is over-expression of Smad7, an intracellular inhibitor of the suppressive cytokine TGF-ß1. The aim of this study was to assess whether Smad7 over-expression occurs in the early and/or late phases of CD. METHODS: Mucosal samples were taken from the neo-terminal ileum of CD patients undergoing ileocolonic resection, with or without (early CD) post-operative endoscopic recurrence, and terminal ileum of CD patients with long-standing disease undergoing intestinal resection (late CD). Smad7 was examined by immunohistochemistry and cytokine expression was analysed by flow-cytometry. RESULTS: Before the appearance of endoscopic lesions, the mucosa of the neo-terminal ileum contained high number of Smad7-expressing cells in both the epithelial and lamina propria compartments. Transition from this stage to endoscopic recurrence was marked by persistence of high number of Smad7-positive cells, which reduced significantly in the late stages of the disease, where Smad7 expression remained, however, greater than that seen in normal controls. In samples with early lesions, Smad7 expression positively correlated with the number of interferon-γ-secreting cells. CONCLUSIONS: Smad7 induction is an early event in the inflammatory sequence occurring in CD, thus suggesting that knockdown of Smad7 can help prevent post-operative recurrence.

BACKGROUND: The coronavirus disease 2019 (COVID-19) has led to a policy of severe restrictions in almost all countries strongly involved by the pandemic. National Health System is among activities suffering from the COVID-19 and the lockdown. AIM: To evaluate the impact of COVID-19 in colorectal cancer (CRC) prevention. METHODS: We report the change in the hospital organization to meet the growing healthcare needs determined by COVID-19. The limitations of CRC prevention secondary to COVID-19 and their effects on the healthcare are analyzed considering the features of the CRC screening programs in the average-risk population and endoscopic surveillance in patients with inflammatory bowel diseases (IBD). RESULTS: The interruption of CRC prevention may lead to a delayed diagnosis of CRC, possibly in a more advanced stage. The economic burden and the impact on workload for gastroenterologists, surgeons, and oncologists will be greater as long as the CRC prevention remains suspended. To respond to the increased demand for colonoscopy once COVID-19 will be under control, we should optimize the resources. It will be necessary to stratify the CRC risk and reach an order of priority. It should be implemented the number of health workers, equipment, and spaces dedicated to performing colonoscopy for screening purpose and in subjects with alarm symptoms in the shortest time. To this aim, the funds earmarked for healthcare should be increased. CONCLUSION: The economic impact will be dramatic, but COVID-19 is the demonstration that healthcare has to be the primary goal of humans.

OBJECTIVES: The aim of this 2-year prospective study was to assess the diagnostic and therapeutic effect of a combined gastro-rheumatological approach in enteropathic spondyloarthritis (eSpA) patients. METHODS: Inflammatory bowel disease (IBD) patients with joint pain were referred by IBD-dedicated gastroenterologists to a dedicated rheumatologist. At baseline and at 3, 6, 12, 24 months, the following parameters were recorded: clinical and biochemical variables, SpA and IBD activity scores, treatment (conventional synthetic; csDMARDs, biologics; bDMARDs). Associations between treatment and patient characteristics were evaluated by logistic regression (AOR [95% CI]). RESULTS: Overall, 229 IBD patients were referred to rheumatologists. eSpA was diagnosed in 147 (64.2%) patients: 96 (65.3%) showing peripheral and 51 (34.7%) axial involvement. IBD included Crohn's disease (CD) in 141 (61.6%) and ulcerative colitis (UC) in 88 (38.4%). bDMARD treatment increased over the follow-up (baseline-24 months: 32.7-60%; AOR 3.45 [1.93-6.2], p<0.001). bDMARD use was less frequent in elderly patients (AOR 0.73 [0.56-0.96], p=0.023), in UC (AOR 0.43 [0.2-0.94], p=0.034) and in patients with peripheral involvement (AOR 0.53 [0.3-1.04], p=0.067). csDMARD use was increased in patients with peripheral involvement (AOR 4.65 [2.09-10.33], p<0.001) and in UC (AOR 2.30 [1.13-4.67], p=0.021). CRP, ESR, ASDAS-ESR levels and BASFI significantly decreased over the follow-up, whereas the pMayo score, BASDAI and HAQ-S were unchanged. CONCLUSIONS: In this prospective study in eSpA patients, a multidisciplinary approach was shown to optimise the therapeutic management and outcome (e.g. disease activity scores). bDMARD use paralleled an improvement in disease activity scores and confirmed a good safety profile.

An interdisciplinary task force of European experts summarizes the value of gastrointestinal ultrasound (GIUS) in the management of acute appendicitis and diverticulitis. Based on an extensive literature review, clinical recommendations for these highly common diseases in visceral medicine are presented.In patients with acute appendicitis, preoperative sonography has been established as a routine procedure in most European countries for medical and legal reasons. Routine sonography in these patients may reduce the rate of unnecessary surgery by half. The sensitivity, specificity, and accuracy of ultrasound reach values above 90â% and are equivalent to CT and MRI. However, the high operator dependence may be a problem, for example in point-of-care ultrasound in emergency departments. Structured training programs, quality controls and standardized ultrasound reporting should be increasingly implemented.In the case of suspected acute diverticulitis, "ultrasound first" should also be a basic element in the approach to all patients. Sonography can confirm the diagnosis and allows early risk stratification. As treatment strategies have become less aggressive and more tailored to the stage of diverticulitis, accurate staging has become increasingly important. GIUS and CT have proven to have similar sensitivity and specificity. Especially in cases of uncomplicated diverticulitis, GIUS will be the one and only imaging procedure. CT may work as a backup and has particular advantages for diverticulitis located in the distal sigmoid, inflammation deep in the small pelvis and insufficient ultrasound scanning conditions. This step-up approach (ultrasound first and CT only in case of a negative or inconclusive ultrasound result) has proven to yield the best accuracy.

The accuracy and usefulness of gastrointestinal ultrasound (GIUS) for detecting activity and complications of inflammatory bowel diseases (IBD), has been reported in studies, promoting this technique as an important tool for the management of IBD patients. Whilst well recognised by international guidelines, standardization and general agreement in the definition of the luminal and extra-intestinal features, still need to be well defined.A task force group of 17 experts in GIUS faced this issue, by developing recommendations and clinical guidelines for the use of GIUS in IBD, under the auspices of EFSUMB. This article presents the consensus on the current data on sonographic features of IBD and summarises the accuracy of different sonographic modalities for the management of IBD patients.

GOALS: To estimate the frequency and cause of nonresponsive celiac disease (CD). BACKGROUND: Treatment of CD is based on life-long adherence to a gluten-free diet (GFD). Some celiac patients experience persistence of symptoms despite a GFD. This condition is defined as nonresponsive CD. STUDY: Celiac patients on a GFD for at least 12 months underwent diet compliance assessment, laboratory tests, breath tests, endoscopic, and histologic evaluations according to the symptoms/signs reported. RESULTS: Seventy of 321 (21.8%) patients had persistent or recurrent symptoms/signs. The cause of symptom persistence was evaluated in 56 of 70 patients. Thirteen of 56 (23%) patients were antiendomysial antibody positive. Among the patients with negative serology, 1 had fibromyalgia, and 3 had evidence that disproved the diagnosis of CD. The remaining 39 patients with negative serology underwent duodenal biopsy sampling, which evidenced histologic alterations in 24 patients. Among the 15 patients with normal histology 3 were lactose intolerant, 9 had irritable bowel syndrome, 2 had gastroesophageal reflux disease, and in 1 patient a cause for the persistent symptom was not identified. In patients with confirmed diagnosis of CD, exposure to dietary gluten was the main cause of persistence of symptoms/signs, and consistently after dietary modification, symptoms resolved in 63% of the patients at later time points during follow-up. CONCLUSION: Nonresponsive CD occurs in nearly one fifth of celiac patients on GFD and its occurrence suggests further investigations to optimize the management of celiac patients.

BACKGROUND: Copy number variations (CNVs) can contribute to genetic variation among individuals and/or have a significant influence in causing diseases. Many studies consider new CNVs' effects on protein family evolution giving rise to gene duplicates or losses. "Unsuccessful" duplicates that remain in the genome as pseudogenes often exhibit functional roles. So, changes in gene and pseudogene number may contribute to development or act as susceptibility alleles of diseases. CASE PRESENTATION: We report a de novo heterozygous 271 Kb microdeletion at 8q21.2 region which includes the family of REXO1L genes and pseudogenes in a young man affected by global development delay, progeroid signs, and gastrointestinal anomalies. Molecular and cellular analysis showed that the REXO1L1 gene hemizygosity in a patient's fibroblasts induces genetic instability and increased apoptosis after treatment with different DNA damage-induced agents. CONCLUSIONS: The present results support the hypothesis that low copy gene number within REXO1L1 cluster could play a significant role in this complex clinical and cellular phenotype.

In Crohn's disease, one of the two major forms of inflammatory bowel diseases in human beings, persistent and chronic inflammation promotes fibrotic processes thereby facilitating formation of strictures, the most common indication for surgical intervention in this disorder. The pathogenesis of Crohn's disease-associated fibrosis is not fully understood, but variants of genes involved in the recognition of microbial components/products [e.g. CARD15 (caspase-activating recruitment domain 15) and ATG16L1 (autophagy-related 16-like 1)] are associated with this phenotype, and experimental evidence suggests that intestinal fibrosis results from an altered balance between deposition of ECM (extracellular matrix) and degradation of ECM by proteases. Studies have also contributed to identify the main phenotypic and functional alterations of cells involved in the fibrogenic process, as well as molecules that stimulate such cells to produce elevated amounts of collagen and other ECM-related proteins. In the present review, we assess the current knowledge about cellular and molecular mediators of intestinal fibrosis and describe results of recent studies aimed at testing the preventive/therapeutic effect of compounds in experimental models of intestinal fibrosis.

BACKGROUND & AIMS: Therapeutic antibodies against tumor necrosis factor α (anti-TNF) are effective in patients with Crohn's disease (CD). Mucosal healing is a surrogate marker of efficacy, but little is known about the effects of anti-TNF agents on structural damage in the intestine. Small-intestine contrast ultrasonography (SICUS) is a valuable tool for assessing CD lesions. A new sonographic quantitative index (the sonographic lesion index for CD [SLIC]) was developed to quantify changes in CD lesions detected by SICUS. We explored whether the SLIC can be used to monitor transmural bowel damage in CD patients during anti-TNF therapy. METHODS: We performed a prospective study of 29 patients with ileal or ileocolonic CD treated with anti-TNF agents; patients underwent SICUS before and after scheduled induction and maintenance therapy. To determine whether changes that can be detected by SICUS occur independently of anti-TNF therapy, 7 patients with ileal CD treated with mesalamine were enrolled as controls. A clinical response was defined as steroid-free remission, with CD activity index scores less than 150. RESULTS: We observed significant improvements in SLIC scores and subscores after induction and maintenance therapy with anti-TNFs, compared with before therapy. SLIC scores and subscores and index classes were improved significantly in patients with vs without clinical responses. Controls had no improvements in terms of CD activity index or SLIC scores, or index classes. CONCLUSIONS: Sonographic assessment using the quantitative index SLIC can be used to monitor changes in transmural bowel damage during anti-TNF therapy for CD.

BACKGROUND &AIM: Post-colonoscopy colorectal cancer (PCCRC) is a colorectal cancer (CRC) diagnosed after a colonoscopy in which no cancer is detected (index colonoscopy). Although the overall cumulative rates of PCCRC are low in both the general population and inflammatory bowel disease (IBD) patients, the overall incidence of PCCRC in IBD is greater than that documented in the general population. This study aimed to identify the index colonoscopy-related factors and patients' characteristics influencing IBD-associated PCCRC development. MATERIALS AND METHODS: We carried out an observational, retrospective study in which IBD-associated PCCRCs were diagnosed between 2010 and 2023. The PCCRC group was compared to a control cohort of IBD patients without CRC matched 1:1 by several demographic and clinical features as well as characteristics of index colonoscopy to minimize selection bias. RESULTS: Among 61 CRCs identified, 37 (61%) were PCCRC. Twelve of 37 (32%) PCCRC were diagnosed within 12 months after the previous negative colonoscopy, 15 (41%) within 12-36 months, and 10 (27%) within 36-60 months. In the multivariate analysis, the inadequate bowel preparation of the index colonoscopy (OR: 5.9; 95% CI: 11.1- 31.4) and the presence of high-risk factors for CRC (OR: 24.03; 95% CI: 3.1-187.8) were independently associated with PCCRC. Conversely, prior exposure to immunosuppressors/biologics (OR: 0.17; 95% CI: 0.03-0.83) and random biopsies sampling at index colonoscopy (OR:0.19; 95% CI: 0.04-0.85) were inversely associated with PCCRC. CONCLUSIONS: More than 50% of CRCs in our population were PCCRC. PCCRCs were associated with previous inadequate cleansing and occurred more frequently in high-risk patients.
RESUMO
OBJECTIVE: Evaluate spondyloarthritis (SpA) incidence in inflammatory bowel diseases (IBD) between patients treated with biological disease-modifying antirheumatic drugs (bDMARDs) and conventional DMARDs (cDMARDs) and define risk factors associated with SpA development. METHODS: Retrospective cohort study was conducted on patients with Crohn's disease (CD) or ulcerative colitis (UC) and divided into two cohorts: cDMARDs or bDMARDs/targeted synthetic (ts) DMARDs treated patients. Rheumatological assessment was performed in patients presenting musculoskeletal symptoms. Multivariate analysis and Kaplan-Meier curves were used to evaluate the adjusted SpA risk development. RESULTS: 507 patients were included in the study. 176 patients with CD received bDMARDs, 112 cDMARDs and 106 new SpA diagnosies were formulated. Females (OR 1.7 (95% CI 1.1 to 3), adjusted p=0.04), non-stricturing/non-penetrating phenotype (OR 2 (95% CI 1.1 to 3.4), adjusted p=0.01), psoriasis (OR 2.1 (95% CI 1 to 4.6), adjusted p=0.04) and non-infectious uveitis (OR 6.8 (95% CI 1.4 to 33.4), adjusted p=0.01) were associated with increased SpA risk development, while bDMARDs usage was protective (OR 0.4 (95% CI 0.2 to 0.8), adjusted p=0.01), statistically higher than cDMARDs throughout the entire follow-up (effect size 0.47). 98 patients with UC received b-tsDMARDs, 121 cDMARDs and 56 new SpA diagnoses were formulated. Females (OR 2.1 (95% CI 1 to 4.3), adjusted p=0.02) and psoriasis (OR 2.7 (95% CI 1 to 6.8), adjusted p=0.03) were associated with increased SpA risk development, while bDMARDs were protective for SpA development for up to 12 months of treatment compared with cDMARDs (p=0.03). CONCLUSIONS: bDMARDs treatment had an impact in reducing SpA development and clinical associated risk factors to transition from IBD to IBD-SpA emerged.

BACKGROUND AND AIM: Suboptimal disease control (SDC) and its contributing factors in IBD according to STRIDE-II criteria is unclear. IBD-PODCAST was a non-interventional, international, multicenter real-world study to assess this. METHODS: Data from the Italian IBD cohort (N=220) are presented here. Participants aged ≥19 with confirmed IBD diagnosis of ≥1 year were consecutively enrolled. A retrospective chart review and cross-sectional assessment by physicians and patients within the past 12 months were performed. SDC or optimal disease control was assessed using adapted STRIDE-II criteria. RESULTS: At the index date, 53.4 % of 116 CD patients and 49.0 % of 104 UC patients had SDC, mainly attributed to a Short Inflammatory Bowel Disease Questionnaire score <50, failure to achieve endoscopic remission, and the presence of active extra-intestinal manifestations in both diseases. Disease monitoring with imaging and/or endoscopy during the previous year was conducted in â¼50 % of patients, with endoscopy performed in â¼40 %. Potential therapeutic adjustments were reported for half of the patients. CONCLUSIONS: This study highlights SDC in a significant portion of IBD Italian patients. These results emphasize the need for more proactive management strategies in both CD and UC patients.
RESUMO
BACKGROUND & AIMS: Small-intestine contrast ultrasonography (SICUS) is a radiation-free technique that can detect intestinal damage in patients with Crohn's disease (CD). We evaluated the diagnostic accuracy of SICUS in determining the site, extent, and complications of CD, compared with computed tomography (CT) enteroclysis as the standard. METHODS: We performed a retrospective analysis of data from 59 patients with CD evaluated by SICUS and CT enteroclysis 3 months apart, between January 2007 and April 2012. We evaluated disease site (based on bowel wall thickness), extent of lesions, and presence of complications (stenosis, prestenotic dilation, abscess, or fistulas) using CT enteroclysis as the standard. Sensitivity, specificity, and diagnostic accuracy were calculated. We determined the correlations in maximum wall thickness and disease extent in the small bowel between results from SICUS and CT enteroclysis. RESULTS: SICUS identified the site of small bowel CD with 98% sensitivity, 67% specificity, and 95% diagnostic accuracy; it identified the site of colon CD with 83% sensitivity, 97.5% specificity, and 93% diagnostic accuracy. Results from SICUS and CT enteroclysis correlated in determination of bowel wall thickness (rho, 0.79) and disease extent (rho, 0.89; P < .0001 for both). SICUS detected ileal stenosis with 95.5% sensitivity, 80% specificity, and 91.5% diagnostic accuracy, and prestenotic dilation with 87% sensitivity, 67% specificity, and 75% diagnostic accuracy. SICUS detected abscesses with 78% sensitivity, 100% specificity, and 97% diagnostic accuracy, and fistulas with 78.5% sensitivity, 95.5% specificity, and 91.5% diagnostic accuracy. CONCLUSIONS: SICUS identified lesions and complications in patients with CD with high levels of sensitivity, specificity, and accuracy compared with CT enteroclysis. SICUS might be used as an imaging tool as part of a focused diagnostic examination of patients with CD.
