RESUMO
BACKGROUND & AIMS: Upadacitinib, an oral Janus kinase inhibitor, achieved significantly higher rates of clinical remission and endoscopic response vs placebo during induction (U-EXCEL [NCT03345849], U-EXCEED [NCT03345836]) and maintenance (U-ENDURE [NCT03345823]) treatment in patients with moderate-to-severe Crohn's disease. Prior biologic failure is often associated with reduced responses to subsequent therapies. This post hoc analysis assessed upadacitinib efficacy by prior biologic failure status. METHODS: Patients were randomized to placebo or upadacitinib 45 mg (UPA45) for 12 weeks (induction). UPA45 clinical responders were enrolled in U-ENDURE and rerandomized to placebo, upadacitinib 15 mg, or upadacitinib 30 mg (UPA30) for 52 weeks. Assessments were by prior biologic failure. RESULTS: Of 1021 patients, 733 (71.8%) had prior biologic failure. Across outcomes and subgroups, upadacitinib-treated patients achieved higher rates vs placebo. During induction, upadacitinib had higher rates vs placebo for clinical remission based on stool frequency/abdominal pain score (without failure: 54.0% vs 28.3%; with failure: 42.2% vs 14.1%) and endoscopic response (without failure: 52.0% vs 16.2%; with failure: 35.7% vs 5.3%). In maintenance, the greatest treatment effect (upadacitinib vs placebo) was among patients with prior biologic failure treated with UPA30 (clinical remission without failure: 58.5% vs 32.7%; with failure: 42.5% vs 8.7%; endoscopic response without failure: 43.9% vs 17.9%; with failure: 38.9% vs 4.0%). Patients without vs with prior biologic failure had fewer adverse events. CONCLUSIONS: Upadacitinib led to higher absolutes rates of clinical and endoscopic outcomes in patients without vs with prior biologic failure. Patients treated with upadacitinib achieved greater rates of clinical and endoscopic improvements vs placebo, regardless of prior biologic exposure.

RESUMO
BACKGROUND & AIMS: Perianal fistulizing Crohn's disease (PFCD)-associated anorectal and fistula cancers are rare but often devastating diagnoses. However, given the low incidence and consequent lack of data and clinical trials in the field, there is little to no guidance on screening and management of these cancers. To inform clinical practice, we developed consensus guidelines on PFCD-associated anorectal and fistula cancers by multidisciplinary experts from the international TOpClass consortium. METHODS: We conducted a systematic review by standard methodology, using the Newcastle-Ottawa Scale quality assessment tool. We subsequently developed consensus statements using a Delphi consensus approach. RESULTS: Of 561 articles identified, 110 were eligible, and 76 articles were included. The overall quality of evidence was low. The TOpClass consortium reached consensus on 6 structured statements addressing screening, risk assessment, and management of PFCD-associated anorectal and fistula cancers. Patients with long-standing (>10 years) PFCD should be considered at small but increased risk of developing perianal cancer, including squamous cell carcinoma of the anus and anorectal carcinoma. Risk factors for squamous cell carcinoma of the anus, notably human papilloma virus, should be considered. New, refractory, or progressive perianal symptoms should prompt evaluation for fistula cancer. There was no consensus on timing or frequency of screening in patients with asymptomatic perianal fistula. Multiple modalities may be required for diagnosis, including an examination under anesthesia with biopsy. Multidisciplinary team efforts were deemed central to the management of fistula cancers. CONCLUSIONS: Inflammatory bowel disease clinicians should be aware of the risk of PFCD-associated anorectal and fistula cancers in all patients with PFCD. The TOpClass consortium consensus statements outlined herein offer guidance in managing this challenging scenario.
RESUMO
PURPOSE OF REVIEW: Intestinal ultrasound (IUS) is a non-invasive, accurate, and well-tolerated tool that provides real-time assessment of inflammatory bowel disease (IBD) activity and is therefore an ideal monitoring tool. This review describes the evolving role of IUS in each phase of clinical management of IBD. RECENT FINDINGS: Accumulating evidence has demonstrated that IUS is an excellent tool for the assessment of suspected IBD, with a very high negative predictive value. It accurately assesses disease activity, disease complications, and in the pre-treatment phase, provides a benchmark for subsequent follow-up. IUS can detect early therapeutic response and correlates well with other established monitoring modalities with arguably superior predictive capabilities and ability to assess a deeper degree of remission, transmural healing (TH). IUS has a crucial role in the management of IBD and has ushered in a new era of monitoring with more rapid evaluation and the opportunity for early optimization, deeper therapeutic targets, and improved outcomes.

BACKGROUND AND AIMS: Ongoing efforts to break the therapeutic ceiling in inflammatory bowel disease include combination therapy approaches. Dual-targeted therapy (DTT) has been reported in case reports and small case series. This report describes our experience with ustekinumab (UST) and upadacitinib (UPA) as DTT in patients with Crohn's disease (CD). METHODS: In this retrospective, observational study, we reviewed medical records of patients with CD treated with combined UST and UPA between April 2021 and July 2022. Clinical remission was defined as Harvey-Bradshaw Index (HBI) ≤ 4, and clinical response was defined as decrease in HBI ≥ 3 or physician's assessment of clinical response. RESULTS: We identified 10 CD patients treated with UST/UPA, with median follow-up period of 10 months (interquartile range (IQR) 7.3-12). Median age was 35.5 years (IQR 28.3-43.8) and median number of prior biologic treatment exposures was 4 (IQR 4-5). Indications for UST/UPA were active CD (n = 6), extraintestinal manifestations (EIM) (n = 2), and both active CD and EIM (n = 2). Five of six patients with active CD achieved clinical remission with UST/UPA. Two patients with active EIM (joint pain) achieved resolution of their symptoms. One patient exhibited improvement in both conditions. Three patients developed mild respiratory symptoms and one experienced bowel obstruction. Two patients developed nausea resulting in de-escalation of treatment interval or discontinuation altogether. CONCLUSION: Based on our case series, combination therapy with UST and UPA may be effective and appears safe in refractory Crohn's disease and for patients with co-existing extraintestinal manifestations.

BACKGROUND: The Endoscopic Healing Index (EHI) analyzes biomarkers in a patient's peripheral blood to assess mucosal healing. We aimed to characterize the effectiveness of the EHI as a predictor of disease activity in a real world clinical setting. METHODS: This retrospective study looked at patients treated and followed up at the University of Chicago Medicine IBD center who had EHI tests done as part of routine clinical care. The results of the EHI were compared with radiological imaging or endoscopy performed within 3 months of the EHI in order to determine accuracy at diagnosing active inflammation. RESULTS: Fifty-five patients with CD and with an available EHI were included in this study. Four (50%) patients with an EHI of < 20 (n = 8) had evidence of objective inflammation. A cutoff of ≤ 20 had a sensitivity of 89% and specificity of 23.5% for predicting no evidence of any objective inflammation with an AUROC of 0.69. This score had a negative predictive value (NPV) of 50% and positive predictive value (PPV) of 72.3%. A cutoff EHI of 30 tended to classify patients as either having objective evidence of inflammation or not more often than FCAL (Correctly classifying inflammation: 89% vs 64%, respectively; p = 0.32). CONCLUSION: In this real world analysis, the EHI showed poor predictive value for the absence of active inflammation as assessed by imaging or endoscopy, has limited utility in confirming deep remission and should be used with another objective modality.

BACKGROUND: Crohn's disease (CD) significantly affects patients' health-related quality of life and well-being. AIMS: Communicating Needs and Features of IBD Experiences (CONFIDE) survey explores the experience and impact of moderate-to-severe CD symptoms on patients' lives and identifies communication gaps between patients and health care professionals (HCPs). METHODS: Online, quantitative, cross-sectional surveys of patients, and HCPs were conducted in the United States (US), Europe (France, Germany, Italy, Spain, United Kingdom), and Japan. Criteria based on previous treatment, steroid use, and/or hospitalization defined moderate-to-severe CD. US and Europe data are presented as descriptive statistics. RESULTS: Surveys were completed by 215 US and 547 European patients and 200 US and 503 European HCPs. In both patient groups, top three symptoms currently (past month) experienced were diarrhea, bowel urgency, and increased stool frequency, with more than one-third patients wearing diaper/pad/protection at least once a week in past 3 months due to fear of bowel urgency-related accidents. HCPs ranked diarrhea, blood in stool, and increased stool frequency as the most common symptoms. Although 34.0% US and 27.2% European HCPs ranked bowel urgency among the top five symptoms affecting patient lives, only 12.0% US and 10.9% European HCPs ranked it among top three most impactful symptoms on treatment decisions. CONCLUSION: Bowel urgency is common and impactful among patients with CD in the US and Europe. Differences in patient and HCP perceptions of experiences and impacts of bowel urgency exist, with HCPs underestimating its burden. Proactive communication between HCPs and patients in clinical settings is crucial for improving health outcomes in patients with CD.

A therapeutic goal for patients with ulcerative colitis (UC) is deep remission including clinical remission and mucosal healing. Mucosal healing was previously defined by endoscopic appearance, but recent studies demonstrate that histological improvements can minimize the risks of experiencing clinical relapse after achieving endoscopic remission, and there is growing interest in the value and feasibility of histological targets of treatment in inflammatory bowel disease, and specifically UC. In this review article, we identify remaining challenges and discuss an evolving role of histology in the management of UC.

PURPOSE: Upadacitinib has been found to improve symptoms as early as day 1 in patients with inflammatory bowel disease. As a result, early and timely initiation of upadacitinib is paramount to prevent hospital admission for an acute flare. The purpose of this study was to identify the time to initiation of upadacitinib, comparing external specialty pharmacies (ESPs) to a health-system specialty pharmacy (HSSP). METHODS: This was a single-center, retrospective study at the University of Chicago Medicine (UCM) Inflammatory Bowel Disease Center and included patients initiated on upadacitinib between March 1, 2022, and April 1, 2023. Data collected included demographics, prior authorization information, appeal information, insurance type, date the prescription was sent, and date the patient initiated therapy (patients were called to confirm the date). The primary outcome evaluated was the days from prescribing to patient initiation. Secondary outcomes included the total time to initiation and the time to notification from insurance regarding determination of a prior authorization or appeal. Patients were excluded if they were lost to follow-up, initiated therapy through alternative means, or had previously initiated upadacitinib. RESULTS: A total of 107 patients were initiated on upadacitinib during the study period (n = 18 through the UCM HSSP, n = 89 through an ESP). The median number of days to patient initiation was 3 days (interquartile range, 3-6 days) for the UCM specialty pharmacy vs 9 days (interquartile range, 4-13 days) for ESPs (P = 0.003). A total of 88.9% of patients filling through the UCM specialty pharmacy initiated upadacitinib within 7 days, compared to 47.2% of patients filling through an ESP (P = 0.001). Seven patients needed earlier initiation of therapy to prevent hospital admission. CONCLUSION: This study validates the ability of HSSPs to initiate therapies earlier than ESPs with a particular focus on upadacitinib.
RESUMO
The mission of the Crohn's & Colitis Foundation is to cure Crohn's disease and ulcerative colitis and to improve the quality of lives of patients living with these diseases-in other words, to care and cure. To achieve these missions, there is a need to identify and prioritize research gaps and approaches to address these gaps, which is the aim of Challenges in IBD 2024. The Foundation convened close to 80 experts in inflammatory bowel disease (IBD), including researchers, clinicians, patients and caregivers, funders, industry representatives, and Foundation scientific staff and organized them into 5 workgroups, one for each of the 5 Challenges topics: Preclinical Human IBD Mechanisms, Environmental Triggers, Precision Medicine, Novel Technologies, and Pragmatic Clinical Research. The findings of these groups outline a research agenda that intends to change the research paradigm in IBD by introducing 2 concepts in the course of IBD that warrant specific focus: interception (during the preclinical phase) and restoration of normal physiology after remission is achieved. We hope these reviews will stimulate innovations in our understanding and management of IBD.

BACKGROUND: Inflammatory bowel disease (IBD) management has become increasingly complex, and education varies across fellowship programs. IBD 101 was designed to introduce first-year gastroenterology (GI) fellows to IBD care and training. METHODS: In 2019, a cohort of fellows participated in a 1-day course with small group learning and group observed structured clinical examinations. Pre- and postcourse surveys were administered to evaluate the course. To assess the long-term impact, surveys were emailed in May 2022 to all third-year fellows from previously participating programs. The primary outcome was comfort managing IBD scenarios and information regarding each fellow's exposure to IBD education. RESULTS: Fifty-five fellows from 32 programs participated. A total of 49 (89%) of 55 completed pre- and postcourse surveys. All fellows agreed that the course content was appropriate. In the postcourse survey, all fellows reported increased comfort managing IBD patients. Ninety-six percent of attendees stated that they would strongly recommend this course. Thirty-six fellows completed surveys in 2022, 21 (58%) attendees and 15 (42%) nonattendees. Attendees reported equivalent or higher levels of comfort compared with nonattendees. Higher global competence was noted among attendees (odds ratio, 5.21; 95% confidence interval, 0.91-29.9; Pâ =â .06) after adjusting for presence of a local IBD specialist, number of IBD patients seen monthly (≤5 vs >5), and rotation through an IBD service. CONCLUSIONS: IBD 101, an introductory course for first-year GI trainees, was associated with increased comfort managing IBD with a durable benefit independent of individual access to IBD education. Continuation of this program will further enhance the IBD education of future GI fellows.
IBD 101 was created to increase exposure for first-year gastroenterology fellows to inflammatory bowel disease. The program was well received by attendees and showed increased comfort and sustained benefit in discussing inflammatory bowel disease diagnosis and management with patients.
RESUMO
Background: The Bowel Ultrasound Score (BUSS) accurately detects therapy-related changes by using the Simple Endoscopic Score for Crohn's disease (SES-CD) as the reference standard. We aimed to evaluate ultrasound remission as a treatment target and its prediction for long-term endoscopic remission. Methods: This single-centre prospective observational study, based at a tertiary referral centre in Milan, Italy, enrolled, between March 1, 2018, and January 31, 2021, adult patients with active CD (SES-CD >2) who were starting biologics. Colonoscopy and IUS was performed at baseline and at 12 months (mean 12.8 ± 4.2). The primary outcome was the predictive value of ultrasound remission at week 12 (BUSS ≤3.52) for long-term endoscopic remission at 12 months. The International Bowel Ultrasound Segmental Activity Score (IBUS-SAS) was also calculated and optimal cut-point to detect endoscopic remission was identified through ROC analysis. Findings: 93 patients with CD were included. Of these, 22 patients (24%) achieved endoscopic remission. Week 12 ultrasound remission predicted endoscopic remission (59% compared with 41% of the patients who were not in ultrasound remission; OR 9.93, 95% CI 3.10-31.80; p < 0.001), while week 12 calprotectin values (<50, <100, <250 µg/g) did not. Week 12 ultrasound activity was associated with failure to achieve long-term endoscopic remission (NPV 87%, PPV 54%). IBUS-SAS cut-off to discriminate endoscopic remission was 22.8 (AUC 0.906). ROC curve comparison showed no-significant difference between BUSS and IBUS-SAS (p = 0.46) for detecting endoscopic remission. Interpretation: Early ultrasound remission predicts long-term endoscopic remission, making it a valuable early treatment target for clinical practice and in clinical trials. Larger multicentre validation studies are warranted to confirm these findings. Funding: None.
RESUMO
BACKGROUND: Wearable sensor devices represent a noninvasive technology to continuously track biomarkers linked to inflammatory bowel disease (IBD). We assessed the inflammatory markers associated with IBD in human perspiration. METHODS: Participants with IBD were monitored for 40 to 130 minutes with a proprietary wearable sensor device used to measure C-reactive protein, interleukin-6, and calprotectin. Sensor response using electrochemical impedance spectroscopy and serum samples were measured on the same day. The Mann-Whitney test was used to analyze the relationship between active and remission IBD in serum and perspiration, classified according to endoscopic reports and serum biomarker levels. Asynchronously collected fecal calprotectin from a subset of the population was similarly analyzed. RESULTS: A total of 33 subjects were enrolled. Expression of calprotectin was significantly elevated in the active cohort compared with the remission cohort in perspiration (P < .05; medianâ =â 906.69 ng/mL; active 95% confidence interval [CI], 466.0-1833 ng/mL; remission 95% CI, 328.4-950.8 ng/mL), serum (medianâ =â 1860.82 ng/mL; active 95% CI, 1705-2985 ng/mL; remission 95% CI, 870.2-1786 ng/mL), and stool (P < .05; medianâ =â 126.74 µg/g; active 95% CI, 77.08-347.1 µg/g; remission 95% CI, 5.038-190.4 µg/g). Expression of CRP in perspiration and serum was comparable between the active and remission cohorts (perspiration: Pâ >â .05; median =â 970.83 pg/mL; active 95% CI, 908.7-992 pg/mL; remission 95% CI, 903.3-991.9 pg/mL; serum: median =â 2.34 µg/mL; active 95% CI, 1.267-4.492 µg/mL; remission 95% CI, 1.648-4.287 µg/mL). Expression of interleukin-6 in perspiration was nonsignificant in the active cohort compared with the remission cohort and was significantly elevated in serum (perspiration: P < .05; median =â 2.13 pg/mL; active 95% CI, 2.124-2.44 pg/mL; remission 95% CI, 1.661-2.451 pg/mL; serum: median =â 1.15 pg/mL; active 95% CI, 1.549-3.964 pg/mL; remission 95% CI, 0.4301-1.257 pg/mL). Analysis of the linear relationship between perspiration and serum calprotectin (R2â =â 0.7195), C-reactive protein (R2â =â 0.615), and interleukin-6 (R2â =â 0.5411) demonstrated a strong to moderate relationship across mediums. CONCLUSIONS: We demonstrate the clinical utility of perspiration as a noninvasive medium for continuous measurement of inflammatory markers in IBD and find that the measures correlate with serum and stool markers across a range of disease activity.
This work establishes the clinical utility of perspiration as a noninvasive, continuous marker for gut inflammation and demonstrates the ability to distinguish between active and inactive inflammatory bowel disease across perspiration, serum, and stool.
RESUMO
INTRODUCTION: To better inform the risk of cuffitis in patients with ulcerative colitis (UC), we aimed to identify its occurrence and associated precolectomy factors in a large multicenter cohort of patients who underwent restorative proctocolectomy (RPC) with stapled ileal pouch-anal anastomosis (IPAA). METHODS: This study was a retrospective cohort analysis of individuals diagnosed with UC or indeterminate colitis who underwent RPC with IPAA for refractory disease or dysplasia at Mount Sinai Hospital or the University of Chicago followed by at least 1 pouchoscopy with report of the pouch-anal anastomosis. The primary outcome was cuffitis defined as ulceration of the cuff as reported in each pouchoscopy report. RESULTS: The pouch-anal anastomosis was mentioned in the pouchoscopy reports of 674 patients, of whom 525 (77.9%) had a stapled anastomosis. Among these, cuffitis occurred in 313 (59.6%) patients a median of 1.51 (interquartile range 0.59-4.17) years after final surgical stage. On multivariable analysis, older age (hazard ratio [HR], 1.01; 95% confidence interval [CI], 1.01-1.02), extensive disease (HR, 1.34; 95% CI, 1.01-1.78), exposure to biologics before colectomy (HR, 2.51; 95% CI, 1.93-3.27), and exposure to at least 2 or more biologics before colectomy (HR, 2.18; 95% CI, 1.40-3.39) were significantly associated with subsequent cuffitis. CONCLUSIONS: In this multicenter study of patients who underwent RPC with stapled IPAA and at least 1 follow-up pouchoscopy, cuffitis occurred in approximately 60% and was significantly associated with extensive disease and exposure to multiple biologics precolectomy.
In this multicenter study of patients who underwent restorative proctocolectomy with stapled ileal pouchanal anastomosis and at least 1 subsequent pouchoscopy, endoscopic cuffitis occurred in 60% and was significantly associated with extensive disease and exposure to multiple biologics.
RESUMO
BACKGROUND: Several studies investigated the risks of neurological conditions in patients with inflammatory bowel disease (IBD), with some variability in findings. We aimed to perform a systematic review and meta-analysis of available evidence to elucidate the association between IBD and the risks of common neurological disorders. METHODS: We conducted a literature search through Embase, PubMed, Scopus, and ProQuest databases from inception to June 30, 2023, to identify cohort studies assessing the risk of developing stroke, all-cause dementia, Parkinson's disease (PD), multiple sclerosis (MS), seizure/epilepsy, and peripheral neuropathy in adult IBD patients compared with non-IBD population. We combined hazard ratios (HRs) with 95% confidence intervals (CIs) to compute pooled estimates using a random-effects model. RESULTS: In total, 22 cohort studies were included, of which 9 studies reported 7074 stroke events in 202 460 IBD patients, 5 studies reported 3783 all-cause dementia diagnoses in 109 602 IBD patients, 7 studies reported 932 PD diagnoses in 354 792 IBD patients, and 1 study reported 6 MS events in 35 581 IBD patients. We observed increased risks of incident stroke (pooled HRâ =â 1.19; 95% CI, 1.06-1.31), all-cause dementia (pooled HRâ =â 1.22; 95% CI, 1.05-1.38), PD (pooled HRâ =â 1.39; 95% CI, 1.20-1.58), and MS (HRâ =â 2.89; 95% CI, 1.02-8.42). No eligible studies were found on peripheral neuropathy and seizure/epilepsy. CONCLUSIONS: Inflammatory bowel disease may be modestly associated with increased risks of stroke, all-cause dementia, and PD. Further longitudinal studies are warranted to investigate potential links with MS, seizure/epilepsy, and peripheral neuropathy, as well as their clinical significance.
This systematic review and meta-analysis of cohort studies aimed to clarify association between inflammatory bowel disease and risks of common neurological disorders. Based on analyses, inflammatory bowel disease may modestly increase risks of stroke, all-cause dementia, and Parkinson's disease vs the healthy population.
RESUMO
BACKGROUND: Fatigue is a burdensome, under-recognized, multidimensional symptom experienced by patients with Crohn's disease (CD). We evaluated the impact of mirikizumab on fatigue and the association between changes in select patient-reported outcomes and clinical measures with changes in fatigue from baseline to week 104 (W104). METHODS: Patients (Nâ =â 191) were randomized (2:1:1:2) to receive placebo (PBO), 200 mg, 600 mg, or 1000 mg of mirikizumab, administered intravenously (IV) every 4 weeks at W0, W4, and W8. Patients who achieved ≥1 point improvement in Simple Endoscopic Score for Crohn's Disease (SES-CD) and received mirikizumab at W12 (rerandomized maintenance cohort) were rerandomized to continue induction IV treatment assignment (IV-C) or received 300 mg of mirikizumab subcutaneously (SC) until W52. Nonrandomized maintenance cohort had endoscopic nonimprovers (1000 mg) and PBO patients (PBO/1000 mg) who received 1000 mg of mirikizumab until W52. Subjects from the maintenance period with clinical benefit received 300 mg SC Q4W from W52 to W104. The Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F) questionnaire was used to assess fatigue, and the FACIT-F associations were assessed using Pearson correlation coefficient. RESULTS: At W12, mirikizumab groups reported improved FACIT-F scores compared with PBO, and improvement was maintained through W52 and W104. Changes in FACIT-F at W52 and W104 had strong correlations with changes at the same time point in quality of life (QoL) scores but lacked correlations with changes in inflammatory biomarkers. CONCLUSIONS: Mirikizumab treatment significantly improved fatigue in patients with moderately to severely active CD, which was sustained to W104. The improvement in fatigue was correlated with improvement in clinical measures and was strongly correlated with improvement in QoL.
Fatigue is a common symptom of Crohn's disease that negatively impacts quality of life. Mirikizumab treatment improved FACIT-Fatigue scores compared with placebo up to week 104. Improvement in fatigue was also associated with improved emotional, social, and physical concepts.
RESUMO
Background: Tofacitinib is an oral Janus kinase inhibitor for the treatment of ulcerative colitis (UC). This analysis assessed the impact of cigarette smoking on tofacitinib efficacy and safety in the UC clinical program. Methods: Efficacy endpoints and adverse events (AEs) were evaluated by smoking status (ever smokers [current and ex-smokers] and never smokers) in the phase (P)2 induction study (baseline demographics and safety only), P3 studies (OCTAVE Induction 1&2, OCTAVE Sustain, OCTAVE Open), and P3/4b RIVETING study. Results: This post hoc analysis included 1156 patients (ever smokers, nâ =â 416 [36.0%; current smokers, nâ =â 59 (5.1%); ex-smokers, nâ =â 357 (30.9%)]; never smokers, nâ =â 740 [64.0%]; median [range] treatment duration 654 [1-2712] and 615.5 [1-2850] days, respectively). Similar proportions of ever smokers and never smokers achieved efficacy endpoints. AEs were reported in 88.7% of ever smokers and 83.8% of never smokers. Overall, 60.6% of ever smokers had an infection (serious infections, 5.5%; herpes zoster [nonserious and serious], 10.8%; Clostridioides difficile infection, 12.0%; lower respiratory tract infection, 19.5%: corresponding values among never smokers were 53.1%, 3.9%, 6.8%, 8.5%, and 11.4%). Major adverse cardiovascular events were reported in 1.0% of ever smokers and 0.7% of never smokers and thromboembolism events (venous and arterial) in 1.0% of ever smokers and 0.9% never smokers. Deaths, malignancies (excluding non-melanoma skin cancer [NMSC]), and NMSC occurred infrequently in ever smokers (0.5%, 2.5%, and 3.7%, respectively) and never smokers (0.1%, 1.5%, and 1.0%, respectively). Colorectal cancer was reported in 0.6% of never smokers; no cases occurred in ever smokers. Conclusions: Efficacy and safety of tofacitinib were generally similar in ever smokers and never smokers. Overall, serious AEs and, as expected, infections were more frequent in ever smokers versus never smokers. This may inform treatment selection and monitoring strategies.

RESUMO
Inflammatory bowel disease (IBD) patients are at increased risk of developing colorectal neoplasia (CRN). In this review, we aim to provide an up-to-date overview and future perspectives on CRN management in IBD. Advances in endoscopic surveillance and resection techniques have resulted in a shift towards endoscopic management of neoplastic lesions in place of surgery. Endoscopic treatment is recommended for all CRN if complete resection is feasible. Standard (cold snare) polypectomy, endoscopic mucosal resection and endoscopic submucosal dissection should be performed depending on lesion complexity (size, delineation, morphology, surface architecture, submucosal fibrosis/invasion) to maximize the likelihood of complete resection. If complete resection is not feasible, surgical treatment options should be discussed by a multidisciplinary team. While (sub)total and proctocolectomy play an important role in management of endoscopically unresectable CRN, partial colectomy may be considered in a subgroup of patients in endoscopic remission with limited disease extent without other CRN risk factors. High synchronous and metachronous CRN rates warrant careful mucosal visualization with shortened intervals for at least 5 years after treatment of CRN.
RESUMO
Calprotectin, a metal ion-binding protein complex, plays a crucial role in the innate immune system and has gained prominence as a biomarker for various intestinal and systemic inflammatory and infectious diseases, including inflammatory bowel disease (IBD) and tuberculosis (TB). Current clinical testing methods rely on enzyme-linked immunosorbent assays (ELISAs), limiting accessibility and convenience. In this study, we introduce the Fab-Enabled Split-luciferase Calprotectin Assay (FESCA), a novel quantitative method for calprotectin measurement. FESCA utilizes two new fragment antigen binding proteins (Fabs), CP16 and CP17, that bind to different epitopes of the calprotectin complex. These Fabs are fused with split NanoLuc luciferase fragments, enabling the reconstitution of active luciferase upon binding to calprotectin either in solution or in varied immobilized assay formats. FESCA's output luminescence can be measured with standard laboratory equipment as well as consumer-grade cell phone cameras. FESCA can detect physiologically relevant calprotectin levels across various sample types, including serum, plasma, and whole blood. Notably, FESCA can detect abnormally elevated native calprotectin from TB patients. In summary, FESCA presents a convenient, low-cost, and quantitative method for assessing calprotectin levels in various biological samples, with the potential to improve the diagnosis and monitoring of inflammatory diseases, especially in at-home or point-of-care settings.
