Pregnancy outcomes among women with inflammatory bowel disease: A UK tertiary centre experience.

Optimal management of inflammatory bowel disease (IBD) in pregnancy is associated with better pregnancy outcomes. We describe management of IBD during pregnancy and maternal and fetal outcomes of patients from a tertiary UK IBD centre. This is a retrospective observational cohort study of all pregnancies occurring between 2015 and 2021 in a large tertiary IBD centre in the UK. IBD activity and management prior to, during and after pregnancy were recorded along with pregnancy and neonatal outcomes. Associations between IBD-focused interventions and any adverse pregnancy outcomes, as well as the association between IBD severity and treatments and adverse maternofetal outcomes were assessed. Pregnancies in 130 women with IBD were included for analysis. The mean maternal age at delivery was 30.5 (± 4.7) years. At conception, 73 women (56.2%) were in clinical remission and 24 (18.4%) were treated with a biologic agent. Active disease during pregnancy, measured by physician global assessment, was less frequent in women who were in clinical remission at conception, compared to those not in remission at conception (16/73 21.9% vs. 39/49 79.6%; data insufficient for eight women). Active IBD at conception was associated with pre-term birth (p = 0.04). Maternal corticosteroid use in any trimester was associated with low birth weight (T1 p = 0.02; T2 p = 0.005; T3 p = 0.007). Active disease (p = 0.008) and steroid use in the third trimester (p = 0.05) were both associated with neonatal infections up to sixmonths after birth. Women in clinical remission at the time of conception have favorable outcomes, consistent with prospective observational studies. Our observations emphasize the importance of high quality IBD care for women pre and post-partum in line with international recommendations.

Sleep quality is associated with reduced quality of life in inflammatory bowel disease through its interaction with pain.

Quality of life is reduced in people with inflammatory bowel disease (IBD) and poor sleep is prevalent in people with IBD. This study aimed to investigate the influence of sleep on quality of life (QoL) in people with inflammatory bowel disease. An online questionnaire was administered through three tertiary IBD centers, social media, and through Crohn's Colitis Australia. The questionnaire included the EQ-5D-5L measures of health-related QoL, the Insomnia Severity Index, the Pittsburgh Sleep Quality Index (PSQI), and validated IBD activity and mental health scores. There were 553 responses included with a diagnosis of Crohn's disease (62.2%), with over half on biologic therapy (53.1%). Poor sleep and clinically significant insomnia were associated with lower QoL (EQ-5D-5L scores: EQVAS, utility score, P < 0.001 for all). Sleep quality scores correlated with the EQ-5D-5L domains of "pain" (ρ 0.35, P < 0.001), "usual activities" (ρ 0.32, P < 0.001), and "depression-anxiety" (ρ 0.37, P < 0.001). After adjusting for demographic variables, IBD activity, and depression and anxiety via multivariate regression, the "pain" domain continued to be associated with PSQI components "sleep quality" (P < 0.001), "sleep disturbance" (P < 0.001), and "sleep duration" (P < 0.001). Clinically significant insomnia was associated with a reduction in QoL (EQVAS, utility score) independent of IBD activity (P < 0.001) and of a similar magnitude to that seen with IBD activity. Health-related QoL in IBD is influenced by aspects of sleep quality irrespective of IBD activity and mental health conditions. The presence of insomnia is associated with a reduction in health-related QoL. Consideration should be given to sleep targeting interventional studies in an IBD population.

Latent profiles of fatigue in inflammatory bowel disease

IntroductionFatigue is prevalent in people with inflammatory bowel disease (IBD) and has been associated with IBD activity, sleep quality, depression, and anxiety. This study aimed to identify fatigue profiles or clusters through latent profile analysis.MethodsAn online questionnaire was administered through three tertiary IBD centres, social media and through Crohn’s Colitis Australia. Fatigue was assessed via the Functional assessment of chronic illness measurement system fatigue subscale (FACIT-F), a validated assessment of fatigue and its severity. Validated measures of anxiety, depression, IBD activity and sleep quality were also included. Latent profile analysis was performed including fatigue, sleep quality, active IBD, and depression and anxiety. The relationships between profiles and IBD and demographic data were investigated.ResultsIn a cohort of 535 respondents, 77% were female, the median age was 41 years (range 32–52 years), and the majority had Crohn’s disease (62%). Severe fatigue was seen in 62%. Latent profile analysis identified four distinct profiles differing by fatigue score - low fatigue, at-risk profile, active IBD, and a poor mental health profile. Female gender, obesity and opioid usage were associated with higher risk of being in the active IBD and poor mental health profile. Age over 40 was associated with lower risk of being in the poor mental health profile.ConclusionLatent profile analysis identifies four classes of fatigue in an IBD cohort with associations with specific risk factors for fatigue along with specific IBD and demographic attributes. This has implications for the classification of fatigue in IBD and treatment algorithms.

Real-world efficacy and safety of tofacitinib treatment in Asian patients with ulcerative colitis.

Real-world data on tofacitinib (TOF) covering a period of more than 1 year for a sufficient number of Asian patients with ulcerative colitis (UC) are scarce. To investigate the long-term efficacy and safety of TOF treatment for UC, including clinical issues. We performed a retrospective single-center observational analysis of 111 UC patients administered TOF at Hyogo Medical University as a tertiary inflammatory bowel disease center. All consecutive UC patients who received TOF between May 2018 and February 2020 were enrolled. Patients were followed up until August 2020. The primary outcome was the clinical response rate at week 8. Secondary outcomes included clinical remission at week 8, cumulative persistence rate of TOF administration, colectomy-free survival, relapse after tapering of TOF and predictors of clinical response at week 8 and week 48. The clinical response and remission rates were 66.3% and 50.5% at week 8, and 47.1% and 43.5% at week 48, respectively. The overall cumulative clinical remission rate was 61.7% at week 48 and history of anti-tumor necrosis factor-alpha (TNF-α) agents use had no influence (P = 0.25). The cumulative TOF persistence rate at week 48 was significantly lower in patients without clinical remission than in those with remission at week 8 (30.9% vs 88.1%; P < 0.001). Baseline partial Mayo Score was significantly lower in responders vs non-responders at week 8 (odds ratio: 0.61, 95% confidence interval: 0.45-0.82, P = 0.001). Relapse occurred in 45.7% of patients after TOF tapering, and 85.7% of patients responded within 4 wk after re-increase. All 6 patients with herpes zoster (HZ) developed the infection after achieving remission by TOF. TOF was more effective in UC patients with mild activity at baseline and its efficacy was not affected by previous treatment with anti-TNF-α agents. Most relapsed patients responded again after re-increase of TOF and nearly half relapsed after tapering off TOF. Special attention is needed for tapering and HZ.

Burden of Mental Health among Patients with Inflammatory Bowel Disease-A Cross-Sectional Study from a Tertiary IBD Center in Hungary.

Background: Inflammatory bowel diseases (IBDs) are chronic conditions that negatively affect the patient's quality of life. With the spread of the biopsychosocial model, the role of mental health in the activity and course of inflammatory bowel disease is becoming more and more recognized. Our study aimed to assess the prevalence of anxiety and depression in IBD patients in our tertiary referral center and determine the predictive factors of these mental conditions. Methods: A total of 117 patients were included consecutively between 1 December 2021 and 28 February 2022. We used a questionnaire to gather demographic information, disease course, and IBD-specific symptoms. We assessed anxiety symptoms using the GAD-7 and depressive complaints using the PHQ-9 questionnaire. We evaluated disease activity using CDAI and pMayo scores. Results: Of the 117 patients (male/female: 63/54), 88 suffered from Crohn's disease, and 29 were diagnosed with ulcerative colitis. Only 6 patients were taking medication for mood disorders, and 38 individuals sought mental support during their lifetime. A total of 15% of the population suffered from moderate-severe anxiety disorder, and 22% were affected by moderate-severe depression. The GAD-7 and PHQ9 values showed a significant correlation between the number of stools, bloody stools, abdominal pain, number of flare-ups, and CDAI scores. Conclusions: Our study confirmed that there is a high incidence of anxiety and depressive symptoms among IBD patients. Our results highlighted the symptoms that could be associated with mental disorders. It is important to assess the mental status of IBD patients to improve their quality of life.

Patient engagement and satisfaction with early phase cell therapy clinical trials at a tertiary inflammatory bowel disease center

Several clinical trials are underway investigating cell and gene therapy, and while these trials are meant to significantly impact patient care, they rely on patient engagement and participation. Unfortunately, clinical trials generally require extensive commitment by subjects. While several studies are using validated surveys to measure patient-reported outcomes, there is a lack of characterization of the patient experience as a subject in these trials. As such, we surveyed mesenchymal stromal cell (MSC) trial participants to understand their perspective. We found that there exists a reliance on one's gastroenterologist and colorectal surgeons for trial introduction and that time and cost were the main barriers to participation. Overall, participants demonstrated high satisfaction with MSC trial participation, but future protocols could incorporate increased use of virtual appointments to optimize patient experience.

TELEHEALTH ENHANCES RETENTION OF PATIENTS WITH INFLAMMATORY BOWEL DISEASE WITHIN A TERTIARY CARE INFLAMMATORY BOWEL DISEASE CENTER

Abstract INTRODUCTION Telehealth care in the ambulatory setting has dramatically increased in the COVID and post-COVID period in medicine. Understanding how this may impact the care of patients (pts) with inflammatory bowel disease (IBD) is important. This study aims to evaluate the pattern of use of telehealth care in a tertiary care IBD center. METHODS Pts seen at a tertiary care IBD center from January 2018 to March 2020 and August 2020 to January 2023 were included. Pts seen between March 2020 and July 2020 were excluded as the institution had mandatory telehealth visits during this period. Data was obtained from the Electronic Medical Record after IRB approval. Office visit types were based on billing codes, and office visits were only included in the analysis if seen by an MD or Advanced practice provider (APP). Drive time in minutes (min) was established from pt addresses using Esri geographic information systems (GIS) data, services and software. All new pts seen in the IBD Center are required to be seen in-clinic. After August 2020, pts seen in follow up can be seen at an in-clinic visit or via telehealth at the patient’s preference. Statistical analysis included Pearson Chi Square analysis for categorical variables and z-tests for means comparisons for continuous variables. RESULTS A total of 7,040 pts included. 56% were female. 89% were white, 7% Black or African American, and 76% had commercial health insurance, 17% had Medicare, 4% Medicaid, and 3% had no health insurance. New pts seen in the post-Covid period had shorter drive times than those seen in the pre-Covid period. (Table 1) Pts who had at least one year of follow up were more likely to be seen as a return visit in the post-Covid period vs the pre-Covid period (84% vs 76%, p&amp;lt;0.05). In the post-Covid period, 62% (3,575/5,750) pts had return IBD care by their MD or APP team delivered via telehealth. Pts seen in telehealth had significantly longer drive times than in-clinic-only pts (median 56.3 min [IQR 93.3] vs median 47.9 min [IQR 89.7]), p&amp;lt;0.001. (Table 2) This was significant for both the telehealth pts who had been seen in-clinic in the pre-Covid period as well as pts who were seen only in the post-Covid period. Pts who continued care only with in-clinic visits in the post-Covid period had significantly shorter drive times than pts who were seen in-clinic pre-Covid (38.8 min [IQR 60] vs 54.2 min [IQR 89.9]), p&amp;lt;0.001. CONCLUSION Telehealth is an effective strategy for continued multidisciplinary care at a tertiary care IBD center. More than half of patients continuing to participate in telehealth for follow up care, and patients were more likely to follow up in the post-Covid period. Patients who live farther away are more likely to continue IBD care via telehealth.

P784 Efficacy of ustekinumab in biologically naïve patients with Inflammatory Bowel Disease

Abstract Background In recent years, there are several new treatment options for inflammatory bowel disease (IBD). Tumour necrosis factor α inhibitors have been joined by novel advanced therapies (vedolizumab, ustekinumab (UST) and Janus kinase inhibitors). These drugs are mostly used as second-line treatments after tumor necrosis factor α inhibitors, with subsequent poorer efficacy. There are few data available on the efficacy of first-line treatment with UST. The aim of our study was to assess efficacy of UST in biologically naïve patients with IBD. Methods All patients older than 18 years who had a confirmed diagnosis of IBD, treated in a tertiary IBD centre (University Medical Centre Ljubljana, Slovenia), who started first-line treatment with UST, were included in this retrospective cross-sectional cohort study. Demographics, clinical characteristics of patients, treatment persistence of UST, clinical disease activity scores, C-reactive protein (CRP), faecal calprotectin (FC), UST concentrations, and endoscopic scores were collected retrospectively in medical files. We determined a Kaplan-Meier curve of treatment persistence. Results We included 71 patients, 11 of which had ulcerative colitis and 60 had Crohn’s disease. Persistence of treatment with UST in biologically naïve patients is 88% at one year (Figure 1). Clinical remission was achieved in 57.7% of patients. Biochemical remission was achieved in 77.6% (CRP&amp;lt;5mg/ml) and 71.1% (FC&amp;lt;100mg/kg) of patients. Endoscopic remission (Mayo endoscopic score &amp;lt;2 in ulcerative colitis or absence of ulcers in Crohn’s disease) was achieved in 50.0% of patients. There was no significant difference (P&amp;gt;0.05) between the median serum concentrations of UST in the group of patients who achieved remission (clinical (5.86μg/ml), biochemical (5.93μg/ml based on CRP, 5.63μg/ml based on FC) and endoscopic (7.14μg/ml)) and who did not achieve remission (5.31μg/ml, 3.25μg/ml, 4.47μg/ml and 4.64μg/ml, respectively). Conclusion Treatment of UST in biologically naïve IBD patients shows high treatment persistence with high biochemical and endoscopic remission rates. It appears that UST is more efficacious if used as first-line therapy compared to the use after other advanced therapies. Further prospective data are needed to confirm our findings.

P831 Acute infusion reactions due to different biologic agents in a large cohort of patients with Inflammatory Bowel Disease

Abstract Background The therapeutic armamentarium for inflammatory bowel disease (IBD) includes several biological agents: infliximab (IFX), adalimumab (ADA), vedolizumab (VED) and ustekinumab (UST). Persistence in therapy with these drugs is not satisfactory, not only due to the loss of clinical response over time but also due to adverse events. Acute infusion reactions (AIRs) occur during or within 24 hours of the infusion. The intensity of AIRs ranges from mild (flushing, dizziness, headache, itching, rash) to severe (anaphylactic). The primary aim of this study was to compare the prevalence rates of AIRs due to the different biological agents in a large cohort of patients with IBD and to assess risk factors for AIRs. Methods All reports of AIRs occurring from January 2021 to October 2023 in IBD patients treated with different biological agents (IFX, ADA, VED and UST) in a tertiary IBD center were retrospectively reviewed. The electronic records of the identified patients were checked for the type of IBD, whether Crohn's disease (CD) or ulcerative colitis (UC), type of biological agent, route of administration (intravenous or subcutaneous), concomitant immunosuppressive therapies, atopic status. Furthermore, the type of treatment for the AIRs and the subsequent therapy undertaken for IBD were also recorded. Results 22 AIRs were recorded out of 1911 patients (1.1%). Of these, 16/550 in patients on IFX biosimilars (2.9 %), 4/590 (0.7%) in patients on ADA biosimilars, 2/318 (0.6%) in patients on VED and 0/453 (0%) in patients on UST (Table 1). The difference in the prevalence of AIR rates observed with the different biological agents was statistically significant (p&amp;lt;0.01). 7 of 16 post-IFX AIRs were moderate-severe, with two episodes of anaphylaxis occurring in patients with CD. The two patients treated with VED experienced only mild symptoms, and no anti-reactive treatment has been used; two mild and two moderate AIRs, respectively, have been reported among patients on ADA. 12 of 22 AIRs occurred during the induction period (from the first to the third administration). 7 of 22 patients had previous allergic reactions. Conclusion Our real-world data on a large population of IBD patients treated with biologic agents confirm that AIRs are rare and occur mainly in patients treated with IFX biosimilars. Most patients who experienced AIRs were atopic. Almost all patients after AIRs changed biological agents within or out of the same biological class. Further studies are necessary to confirm our results and better characterise the profile of patients at greater risk of AIRs.

P787 Use of upadacitinib to treat IBD in post-liver transplant

Abstract Background Approximately 2% of patients with inflammatory bowel disease (IBD) have concurrent primary sclerosing cholangitis (PSC). Liver transplantation (LT) is sometimes required due to progressive PSC. However, the management of active IBD post-LT is challenged due to concomitant anti-rejection immunotherapies. Janus kinase inhibition has been previously described to have anti-rejection properties in patients who have had renal transplants. Here, we describe our experience with upadacitinib (UPA), a selective Janus kinase-1 inhibitor, for post-LT active IBD combined with anti-rejection immunosuppression therapy. Methods This is a retrospective, single-center observational study in a tertiary IBD center. We identified patients with LT treated with UPA for their IBD. Patient related outcomes including transplanted liver status and clinical efficacy and safety of UPA for IBD activity were reviewed. Results We identified four patients (3 with Crohn’s disease, 1 with ulcerative colitis) treated with UPA after LT due to PSC, with the UPA indication for the treatment of IBD (n=3) and organ rejection (n=1). Median follow-up was 3 months (interquartile range (IQR) 1.5-7.1), median age at starting UPA was 41.5 years (IQR 40-44), and median interval from the transplant was 3.2 years (IQR 2.3-5.6). Two patients with Crohn’s disease clinically responded to UPA, one weaned off prednisone 30mg/day and remained in clinical remission after reducing UPA from 30 mg/day to 15 mg/day. Two patients developed elevated AST/ALT of up to 107/57 U/L and 83/228 U/L; one required discontinuation of UPA at one month with subsequent AST/ALT normalization; the other remained on UPA with 1.5 month follow-up so far. One UC patient was treated with UPA combined with vedolizumab in an attempt to discontinue prednisone for their immunosuppression for organ rejection, however, they were unable to wean off prednisone due to recurrent ALT and Alk Phos elevations. One patient acquired a mild case of COVID-19 which resolved without change in therapy. No life-threatening adverse events were observed. Conclusion We describe 4 patients with IBD who had LT for PSC and who were treated with UPA with successful management of active IBD in 2 cases but lack of efficacy in one case and liver enzyme elevations limiting UPA use in a second. These findings support further exploration of this novel mechanism for treatment of IBD in the post-LT setting.

P494 Efficacy and safety of Upadacitinib in moderate to severe paediatric Crohn’s disease and ulcerative colitis in a tertiary Paediatric IBD (PIBD) centre – A case series

Abstract Background Upadacitinib is a selective Janus kinase 1 inhibitor approved for the treatment of patients 18 years and older with the diagnosis of Crohn’s disease and ulcerative colitis. Although there is promising data for its use in adult inflammatory bowel disease (IBD), limited data are currently available on its use in paediatric IBD. We present our experience in this case series of patients ≤ 18 years on Upadacitinib. Methods We identified patients under the age of ≤ 18 years, started on Upadacitinib for the indication of IBD. Data on demographics, disease subtype, duration on Upadacitinib, number of biologic failures, tofacitinib use, concomitant biologic use, adverse events and clinical remission were gathered. Results 12 patients with paediatric IBD (median age at Upadacitinib start 15.5 years, range 13.9 to 17.8 years, 8 (67%) males, were identified. 7 patients had Crohn’s disease, 3 patients had ulcerative colitis and 2 patients had IBD unclassified. 4 patients (33%) were diagnosed under the age of 6 years with early onset IBD (EOIBD), 1 was 3.5 years old, 1 was 4 years old and 2 were 5 years old. 11/12 (92%) patients had failed 3 or more biologics. Upadacitinib was used as monotherapy in all patients and previous biologic treatments were stopped. 1 patient with a partial response to tofacitinib was switched to Upadacitinib. All patients had active disease at commencement of Upadacitinib. All 12 (100%) patients were started on 45 mg of Upadacitinib. 8/12 (67%) patients have been followed up for at least 8 weeks. Out of the 8 patients, 5/8 (63%) patients were in clinical remission between 8-16 weeks of therapy, 2/8 (25%) had partial response and 1/8 (13%) has been refractory to treatment. Relapse of symptoms was noted in 1 patient after dose was dropped to 30 mg; this patient had achieved remission on 45 mg. No serious adverse events occurred; 2 patients noted to have increased triglycerides (max 5.75mmol/L; range 0.38-1.58mmol/L). 1 of them had previous exposure to tofacitinib and the triglycerides were already raised prior to starting Upadacitinib. 1 patient developed headaches, as a result, Upadacitinib dose was decreased. There were no incidences of shingles or other serious infections. Abbreviations CD, Crohn's disease; UC, ulcerative colitis; IBD-U; inflammatory bowel disease unclassified; Upa, upadacitinib; AEs; adverse events Conclusion The patients in this case series, started on Upadacitinib, are a heterogeneous group with refractory disease. In these paediatric and adolescent patients Upadacitinib seemed safe and efficacious with a low side effect profile. Further national and international collaborative studies are needed to confirm our findings. Table 1. Patient Characteristics

Transitioning patients from intravenous to subcutaneous infliximab and vedolizumab for inflammatory bowel disease: what is the opportunity cost of improving access to healthcare?

Biologic drugs are highly effective for inflammatory bowel disease (IBD) management but are key drivers of costs of care especially when administered intravenously (i.v.). Availability of subcutaneous (SC) formulations has increased convenience for patients and improved access to care, but at the cost of revenue to health services. To evaluate the economic impact of transitioning a tertiary centre IBD cohort from i.v. to SC biologic administration and assess the implications for key stakeholders. A retrospective analysis of all patients who received i.v. infliximab or vedolizumab in the outpatient infusion centre of a tertiary IBD centre between July 2019 and June 2021 was undertaken. Data were collated from electronic medical records, pharmacy dispensing systems and the hospital business intelligence unit. An economic analysis and theoretical financial/capacity impact analysis of a transition to an SC model were estimated under two scenarios using a random 10% and 30% of the patient cohort. Transitioning our IBD cohort from i.v. to SC administration would result in a loss to our health service of AU$2 732 123.75, composed of AU$1 463 003.75 in Weighted Inlier Equivalent Separation (WIES) and AU$1 269 120 in drug procurement revenue. However, it would ease capacity in the infusion centre by up to 5256 h. Transitioning patients to SC administration results in improved access to infusion centres and substantial savings to state governments; however, switching results in a loss of i.v. biologic-generated WIES to health services. Alternative funding models are required to achieve sustainability in IBD care and reduce reliance on i.v. biologic-generated income.

Depression influences fatigue in inflammatory bowel disease amongst other factors: a structural modelling approach.

Fatigue is common in people with inflammatory bowel disease (IBD) and is associated with IBD activity, sleep disturbance, anxiety and depression. The relative contribution of these factors to fatigue is unclear. This study aimed to investigate the relationship between fatigue and these factors through a novel approach using structural equation modelling. Online questionnaire circulated via three tertiary IBD centres and Crohn's Colitis Australia. Fatigue was assessed using the Functional assessment of chronic illness measurement system fatigue subscale. Validated measures of sleep, anxiety, depression and IBD activity were included. Following correlation analyses, a structural equation model was developed for the outcome of the fatigue score. Direct and indirect effects were calculated. There were 630 complete responses to the online questionnaire. The median age of respondents was 41 with the majority female and over half (52%) on biologic medication. Structural equation models for Crohn's disease and ulcerative colitis demonstrated a good fit. In Crohn's disease, the relationship between IBD activity and fatigue was mostly mediated indirectly through the influence of IBD activity on sleep, anxiety and primarily depression. Sleep quality mediated the influence of IBD activity and the indirect effects of depression on fatigue, but not anxiety. Unlike in Crohn's disease, the direct influence of IBD activity on fatigue in ulcerative colitis was non-negligible, although remained of lesser magnitude than the indirect effect of IBD activity on fatigue. Depression was the primary indirect mediator of the influence of IBD activity on fatigue in ulcerative colitis. In Crohn's disease, IBD activity leads to fatigue through its influence on sleep quality and mental health. The data suggest treatment of clinically significant depression, in both ulcerative colitis and Crohn's disease, may result in the largest decline in fatigue score compared to other variables. Treatment algorithms for fatigue should consider depression a priority.

ASSESSMENT OF QUALITY OF LIFE IN ELDERLY PATIENTS WITH INFLAMMATORY BOWEL DISEASE WITH MILD ACTIVITY AND IN CLINICAL REMISSION.

Inflammatory bowel disease (IBD), represented by Crohn's disease (CD) and ulcerative colitis (UC), is a chronic condition that affects all age groups, predominantly in young individuals. Currently, an increase in the prevalence of IBD has been documented, in parallel with the increase in the elderly population. The scarce number of studies that better characterize the impact of IBD on Quality of Life (QoL) in the elderly motivated the present study. To evaluate the impact of IBD on the QoL of elderly people treated at a Tertiary IBD Center. Prospective cross-sectional study that included elderly patients (age ≥60 years) with quiescent or mildly active IBD treated at the HU-UFJF IBD Center between March 2019 and December 2022. Elderly companions without severe comorbidities who attended the consultation with the patients were included as a control group. Sociodemographic and IBD-related characteristics were recorded. QoL was assessed using previously validated questionnaires (WHOQOL-BREF and IBDQ). Patients with IBD with moderate to severe activity, history of recent or imminent hospitalization, serious or opportunistic infections in the last 6 months, previous neoplasia, dementia, and difficulty understanding/fulfilling the questionnaires were excluded. A total of 123 patients were included (74 with IBD and 49 in the control group), with a mean age of 67±6.2 years, 52.7% with CD, and 47.3% with UC. Mild disease activity was observed in 31.1%. Both groups (IBD patients and control) were comparable based on age, sex, BMI, and the Charlson Comorbidity Index. Patients with IBD and controls had similar QoL scores in the different domains assessed by the WHOQOL-BREF. On the other hand, when evaluating the general facet of QoL, IBD patients had significantly lower scores in General QoL (3.71±0.87 versus 4.02±0.62, respectively; P=0.021) and General Health (3.32±1.05 versus 3.69±0.94, respectively; P=0.035). The presence of mildly active IBD negatively impacted the general health score (2.91±0.99 versus 3.47±1.04, respectively; P=0.035) and the physical domain of the WHOQOL-BREF (12.27±2.63 versus 13.86±2.61, respectively; P=0.019) when compared to patients in remission. Conversely, no impact on QoL was observed with the Application of the IBDQ questionnaire regarding the type of the disease (161±38.5 versus 163.1±42.6 for CD and UC, respectively; P=0.84) or the presence of activity (152.5±38.8 versus 166.4±40.5, respectively; P=0.17). No statistically significant differences were found between elderly patients with mildly active or quiescent IBD and elderly patients without IBD when observing global QoL scores. However, IBD negatively impacted the general facet of QoL, just as mild activity was associated with lower scores in general health and the physical domain assessed by the WHOQOL-BREF. Patients with IBD treated with biological therapy had better Qol than those on conventional therapy. Future studies are needed to choose the most appropriate tool for assessing QoL in this population.

HOSPITALIZATION, USE OF BIOLOGICS AND SURGERY RATES IN INFLAMMATORY BOWEL DISEASES: A SINGLE-CENTRE COMPARATIVE ANALYSIS BETWEEN PUBLIC AND PRIVATE HEALTHCARE SYSTEMS IN A TERTIARY UNIT FROM LATIN AMERICA.

Inflammatory bowel diseases (IBD) have rising incidence and prevalence rates globally. In IBD, there are scarce stu-dies comparing differences between patients according to socioeconomic status. Our aim was to comparatively evaluate hospitalizations, use of biologics and rates of surgery in patients with IBD between public and private healthcare systems. Single-center retrospective cohort study in patients with IBD from a tertiary referral unit from Latin America, between 2015 and 2021. CD and UC patients were classified into two subgroups: public and private systems. Demographic characteristics, hospitalizations, need for surgery and biologics were compared. A total of 500 patients were included, 322 with CD and 178 with UC. CD-related hospitalizations were frequently observed in both healthcare systems (76.28% in private and 67.46% in public). More than half of the patients had been submitted to one or more CD-related abdominal surgery, with no significant difference between the subgroups. Although there was no difference in the rates of use of biological therapy in CD subgroups, infliximab was more used in the public setting (57.69% vs 43.97%). There was no difference in UC-related hospitalizations between the subgroups (public 30.69% and private 37.66%) as well as the rates of colectomy (public: 16.83%, private: 19.48%). Biologics were prescribed almost twice as often in private as compared to public (45.45 vs 22.77%). There were no differences in the rates of hospitalization and abdominal surgery between the systems. In patients with UC, there was greater use of biological therapy in the private healthcare setting. • In a tertiary IBD center in Latin America. • More than half of the patients had been submitted to one or more CD-related abdominal surgical procedure. • Between the two healthcare systems, there was no difference in the rates of use of biological therapy in patients with CD, and in UC-related hospitalizations. • Biologics were prescribed almost twice as often in the private system as compared to the public in patients with UC.

Dermal lesions associated with anti-tumor necrosis factor α therapy in patients with inflammatory bowel disease (IBD): findings from a tertiary IBD center in Poland.

There are scarce data on the occurrence of dermal lesions in patients with inflammatory bowel disease (IBD) treated with anti-tumor necrosis factor α (anti-TNF‑α) antibodies. Characteristics of the skin lesions, their clinical course, and impact on treatment are of high importance. The aim of this study was to assess the prevalence, risk factors, and clinical sequelae of dermal lesions in IBD patients treated with anti-TNF‑α antibodies. This retrospective, single‑center study evaluated 541 IBD patients treated with anti-TNF‑α drugs and 688 IBD individuals with no history of anti-TNF‑α treatment. Higher prevalence of dermal lesions was noted in the patients on anti-TNF‑α therapy than in the individuals not receiving such treatment (30.9% vs 16.4%; P <0.001). Risk factors for dermal lesions included higher body mass index (BMI), Crohn disease located in the small intestine, and longer duration of therapy. Some types of dermal lesions were associated with anti-TNF‑α therapy; these included infusion reactions and injection site reactions, cutaneous infection, psorasiform reactions, and lupus‑like symptoms. Overall, 5.9% of the patients on anti-TNF‑α therapy required treatment change or discontinuation due to dermal lesions (alopecia, lupus‑like symptoms, melanoma, and psoriasis). We observed a higher prevalence of dermal lesions in patients with IBD undergoing anti-TNF‑α therapy than in the treatment-naive group, although development of such lesions rarely necessitated a change in or discontinuation of treatment. Patients with IBD should regularly undergo follow-up dermatologic evaluation, which may improve detection of dermal lesions. Moreover, biologic therapy in IBD patients requires close collaboration with an experienced dermatologist.

Factors influencing the healthcare transition in Chinese adolescents with inflammatory bowel disease: a multi-perspective qualitative study

BackgroundThe development and implementation of the transition from pediatric to adult healthcare systems for adolescents with inflammatory bowel disease (IBD) should consider stakeholders’ perceptions. This study aimed to explore the factors influencing the transition of Chinese adolescents with IBD from the perspectives of patients, parents, and healthcare providers.MethodsA descriptive qualitative research was conducted. Purposive sampling was used to recruit 36 participants, including 13 patients, 13 parents, and 10 providers, from a tertiary pediatric IBD center, a tertiary adult IBD center, and the China Crohn’s & Colitis Foundation in Zhejiang Province, China. Individual semi-structured interviews were used to collect data on facilitators and barriers to the transition process. Conventional content analysis was used to analyze the interview transcripts.ResultsNine primary themes were identified. Patients with young age, prolonged disease duration, severe disease, academic pressures such as the Gaokao, low level of disease acceptance, limited transition consciousness, low self-efficacy, poor transition communication, and inadequate medical transition system serve as barriers. While patients with the mentality of guilt towards their parents; parents with low education levels and intensive work schedules, high levels of disease acceptance, and situations of parent-child separation; stakeholders with high transition consciousness, high transition self-efficacy, and effective transition communication act as facilitators. Furthermore, community support and hospital guide services were also contributing factors during the transition.ConclusionsThis study offers comprehensive insights into the factors affecting the transition of Chinese adolescent IBD patients. The process is continuously influenced by stakeholders, community, and healthcare environments and policies. Identifying these factors provides healthcare providers with a reference for developing and implementing targeted transition interventions.

Focal loss of mural stratification as a radiological predictor for small bowel adenocarcinoma in Crohn's disease

AimPatients with Crohn's disease (CD) are at higher risk of small bowel adenocarcinoma (SBA). We aimed to identify radiological predictors of SBA in CD. MethodsWe conducted a retrospective case-control study at two tertiary inflammatory bowel disease centers and identified CD patients diagnosed with SBA between 2003 and 2019. Patients were matched with up to four controls. Pre-operative imaging (magnetic resonance imaging (MRI) or computed tomography (CT)) were reviewed by three gastrointestinal radiologists. ResultsNineteen patients with CD-associated SBA with a mean age of 54.9 and 32 matched controls were included. Mean length of small bowel involvement was 216 (± 188) mm in the SBA group versus 156 (± 167) mm in the control group (p = 0.76). Only 11.8 % of cases had a diagnosis of SBA made preoperatively. In univariate analysis, focal loss of mural stratification (odds ratio [OR], 11; 95%CI, 2.43–49.5, p = 0.002), and wall thickening (OR, 1.32; 95%CI, 1.05–1.66, p = 0.02) were significantly associated with SBA. After adjustment, focal loss of mural stratification was the only independent risk factor (OR, 11; 95 % CI, 2.43-49.5, p = 0.002). ConclusionsFocal loss of mural stratification was identified as a predictor of CD-associated SBA, which should be described in imaging reports and further validated.

Insomnia is common in inflammatory bowel disease (IBD) and is associated with mental health conditions as well as IBD activity.

Insomnia is common in people with chronic medical conditions, such as inflammatory bowel disease (IBD), and is readily treatable through cognitive behavioral therapy for insomnia. This study aimed to describe the associations with insomnia in people with IBD and its relationship to IBD-related disability. An online questionnaire was administered through 3 tertiary IBD centers, social media, and Crohn's Colitis Australia. The questionnaire included the Insomnia Severity Index (ISI), a validated assessment of insomnia. Measures of anxiety, depression, physical activity, and disability were also included. IBD activity was assessed using validated patient reported scores. A multivariate model was constructed for clinically significant insomnia and ISI scores. Subpopulations of Crohn's disease and ulcerative colitis were considered. In a cohort of 670 respondents the median age was 41 years (range, 32-70 years), with the majority female (78.4%), the majority had Crohn's disease (57.3%). Increasingly severe disability was associated with worse insomnia score. Clinically significant insomnia was associated with clinically active IBD, abdominal pain, anxiety, and depression, in a multivariate model. In an ulcerative colitis population, Simple Clinical Colitis Activity Index components of general well-being and urgency were associated with worse ISI score in a model including depression and anxiety. In those with Crohn's disease, the multivariate model included Harvey Bradshaw Index score in addition to depression and anxiety. Insomnia is common in people with IBD and is associated with increased disability. Abdominal pain and mental health conditions should prompt consideration for screening for insomnia and referral for cognitive behavioral therapy for insomnia.

Higher Adalimumab Trough Levels Are Associated with Histologic Remission and Mucosal Healing in Inflammatory Bowel Disease.

(1) Many patients with inflammatory bowel disease (IBD) in endoscopic remission have persistent histologic activity, which is associated with worse outcomes. There are limited data on the association between adalimumab drug concentrations and histologic outcomes using validated histologic indices. We aimed to assess the relationship between adalimumab concentrations and the Robarts Histopathology Index (RHI). (2) Patients from a tertiary IBD center from 2013 to 2020 with serum adalimumab (ADA) trough concentrations measured during maintenance therapy (≥14 weeks) and a colonoscopy or flexible sigmoidoscopy with biopsies performed within 90 days of drug level were included. Blinded histologic scoring using the RHI was performed. Primary analysis assessed the relationship between adalimumab drug concentrations and histologic remission using receiver operating characteristic curve analysis. (3) In 36 patients (26 Crohn's Disease, 9 ulcerative colitis, 1 indeterminate), median adalimumab concentrations were higher (17.3 ug/mL, 12.2-24.0) in patients with histologic remission compared to those without (10.3 ug/mL, 6.8-13.9, p = 0.008). The optimal ADA concentration identified using the Youden threshold was ≥16.3 ug/mL (sensitivity 70%, specificity 90%). Patients with ADA ≥ 16.3 ug/mL had higher histologic remission rates (78%) compared to lower ADA concentrations (14%, p= 0.002), as well as higher mucosal healing rates (86%) compared to lower levels (12%, p = 0.001). Symptoms correlated weakly and non-significantly with both histologic (RHI) scores (r = 0.25, p = 0.2) and adalimumab concentrations (r = 0.05, p = 0.8). (4) The current study demonstrated that higher serum adalimumab concentrations (≥16.3 ug/mL) are needed for histologic remission and mucosal healing assessed using the RHI.
