P112 Impact of the SARS-COV2 pandemic on patients with inflammatory bowel disease - Preliminary results of a prospective, single-center study

Abstract Background The real impact of COVID-19 infection on patients with Inflammatory Bowel Disease (IBD) is unknown. It was speculated that this population could be a risk group. The aim of this study is to evaluate the incidence of SARS-CoV2 infection, the impact of initiation/change of IBD therapy and its morbidity and mortality, during the COVID-19 pandemic in Portugal. Methods Prospective cross-sectional study. Patients with IBD followed at a Gastroenterology Department in an area with a high incidence rate of SARS-CoV2 were included, from 01/03/2020 to 31/08/2020. Data was obtained through telephonic appointments, hospital inpatients admissions, Emergency Department Service and Day Hospital episodes. Results 335 patients were included, 194 female, with a mean age of 47.4 years (18–88). 200 had Crohn’s disease (CD), 132 Ulcerative Colitis, 3 unclassified colitis. 320 were on therapy (95.5%): salicylates n=230 (71.9%), systemic corticosteroids n=34 (10.6%) (18 started during the pandemic), thiopurines/methotrexate n=117 (36.6%) (8 started in this period), biological n=148 (46.3%) (14 started in this period). 7 patients (2.2%) triple immunosuppressed. 75 patients had disease in remission, 232 mild/moderate, 28 severe disease (requiring hospitalization). SARS-CoV2 infection was observed in 3 patients (incidence rate: 0.89%), treated as an outpatient basis. 2 male, mean age 58 years, 2 with CD. Comorbidities: 0: n = 1; 2: n = 1; 4: n = 1. 2 patients were on salicylates and one on adalimumab (monotherapy, before the pandemic). There were no deaths. Conclusion All patients started or maintained their IBD therapy according to current international guidelines. A significantly higher incidence of COVID-19 infection than that of the local and Portuguese population in general has not been documented. According to our preliminary results, the population with IBD does not appear to be a risk group for acquiring infection or having a severe course of the disease.

The Impact

Introduction: Patients with inflammatory bowel disease (IBD) do not seem to be at increased risk of infection by SARS-CoV-2, but there is a concern whether immunosuppressive therapy may be associated with more severe disease. Several clinical practice recommendations have been published to help guide IBD care during the COVID-19 pandemic. Nonetheless, few studies have addressed patients’ perspectives and fears. We aimed to evaluate Portuguese IBD patients’ perspectives on the clinical management of their disease during the SARS-CoV-2 pandemic as well as the impact on their professional life. Methods: An anonymous electronic survey was created using REDCap and was distributed by the Portuguese Association of Inflammatory Bowel Disease (APDI) between May and August 2020. Patients’ perspectives on immunosuppressive therapy, disease management, interaction with gastroenterology departments, and the impact of the pandemic in their professional life were assessed. Patients’ proposals to improve medical care were also evaluated. Descriptive analysis and logistic regression were performed. Results: A total of 137 participants answered the survey (79.6% females, mean age 41.7 ± 12.1 years). Although having IBD and receiving treatment with immunosuppressors (thiopurines, steroids, or biologics) were considered promotors of anxiety, most patients (85.4%) agreed that disease remission was a priority and only a minority of patients interrupted their treatment during the pandemic. In multivariate analysis, active disease, biologic treatment, and use of corticosteroids in the last 3 months were perceived by the patients as high-risk features for increased risk of SARS-Cov-2 infection and more severe disease. Fifty-nine patients (44%) believed that their follow-up was influenced by the pandemic and only 58.8% felt that they had the opportunity to discuss their therapeutic options with their doctor. Sixty-three patients (46.0%) were working from home during the pandemic, although this decision was related to IBD and immunosuppressive therapy in only 36.5 and 39.7% of the cases, respectively. Areas where care could have been improved during the pandemic were identified by patients, namely enhancement of the communication with IBD professionals, conciliation of telemedicine with face-to-face appointments, and facilitation of the interaction between patients and employers. Conclusion: Most patients agreed that maintaining IBD remission is crucial, and only a minority of the patients stopped their treatment as per their own initiative. IBD status only had a small influence on patients’ professional activity during the COVID-19 outbreak, with most changes being related to the pandemic itself.

Abstract Background Malnutrition is prevalent among patients with inflammatory bowel disease (IBD). Nutritional profiles among Asian patients with IBD have seldom been investigated. We assessed the prevalence of and risk factors for malnutrition, use of nutrition support, and sociopsychological status associated with malnutrition among patients with IBD in China. Methods Patients with ulcerative colitis (UC) and Crohn’s disease (CD) recruited from 43 tertiary referral hospitals were screened for malnutrition and nutrient deficiencies in this cross-sectional study. The use of nutrition support was recorded. The sociopsychological status was assessed by subjective questionnaires. Factors associated with malnutrition were analyzed, and multivariate regression was used to determine independent predictors for malnutrition. Results We recruited 1013 patients with a median age of 35.0 years, 58.5% of them had CD, and 61.4% of all patients were male. Overall, 49.5% (501) of patients were diagnosed with malnutrition, including 57.0% of patients with CD, 38.8% of patients with UC, and 44.1% of patients with quiescent or mildly active disease. Nutrient deficiencies were prevalent despite the absence of malnutrition. Malnutrition was associated with adverse sociopsychological status, including decreased social support, higher perceived stress, and impaired quality of life. Moderate to severe disease activity and extensive disease were two independent risk factors for malnutrition. In total, 41.6% of patients received nutrition support, and patients with risk factors were more likely to receive nutrition support. Conclusions Malnutrition was highly prevalent and associated with adverse consequences in Chinese patients with IBD. Malnutrition screening and early initiation of nutrition support are essential components in IBD care.

Chronic Inflammatory Bowel

Abstract Background Sexual dysfunction is often associated with impaired body image and quality of life in patients. However, little data exists on sexual dysfunction (SD) in patients with Chronic Inflammatory Bowel Disease (IBD). The aim of this study was to assess the prevalence and risk factors for sexual dysfunction in patients with IBD. Methods This is a cross-sectional study of all patients followed for IBD. Sexual function was assessed by the Female Sexual Index Function (FSIF) for women and the International Index of Erectile Function (IIEF) for men. Sexual dysfunction was confirmed when the total FSIF score was less than 26, or the IIEF score less than 26. Crohn’s disease (CD) activity was assessed by the Harvey-Bradshaw index (HBI), and that of ulcerative colitis (UC), by the clinical Mayo scores. Results We collected 100 patients, with a mean age of 42.18 ± 15.71 and a sex ratio (M / F) = 1.5. Sixty eight patients had CD and 32 patients had UC. Ano-perineal manifestations were present in 38.2% of cases. Severe disease activity was noted in 14 patients (20.6%) with CD and 10 patients (31.3%) with UC. Twelve patients had proctitis. 38% of patients had surgical treatment: 18.75% for patients with UC and 47.05% for those with CD. Total colectomy was performed in 12% of cases. At the time of the study, 20% of patients were on systemic corticosteroid therapy, 22% on Azathioprine, 4% on Salazopyrine, 8% on 5-ASA and 46% on Anti-TNFα. Sexual dysfunction was reported by 42.9% of women: 57.14% (UC) vs 38.46% (CD) (p = 0.042). On the other hand, sexual dysfunction was reported by 27.6% of men: 22.2% of men with UC and 28.57% with CD, with no statistically significant difference (p = 0.78). A significant association was found between sexual dysfunction and the degree of disease activity (p <0.001 for CD, p = 0.003 for UC), as well as pancolitic involvement in women with UC (p = 0.002). However, the presence of anoperineal manifestations, rectal involvement and history of surgery were not significantly associated with the frequency of sexual disturbances. Conclusion Our study showed a high prevalence of sexual dysfunction in patients with IBD. Training gastroenterologists in the management of sexual dysfunction would make it possible to satisfy patient expectations.

Abstract Background Evidence on the adoption of different pharmacologic strategies in inflammatory bowel disease (IBD) in the real-world setting in Latin America is scarce. Herein, we describe the clinical characteristics and therapeutic strategies of IBD patients (pts) in Argentina. Methods RISE AR (NCT03488030) was a multicentre, non-interventional study with a cross-sectional evaluation and a 3-year retrospective data collection period conducted in Argentina (12/2018-05/2019) to assess the use of IBD treatments. Adult pts (≥18 years old) with a previous diagnosis of moderate-to-severe ulcerative colitis (UC) or Crohn′s disease (CD) based on clinical, endoscopic or imaging criteria at least 6 months prior to enrolment, were included. Results Overall, 101 CD and 145 UC pts were included. Median (range) age (years) at enrolment was 39.5 (18.2–74.0) for CD (51.2% female) and 41.9 (18.0–80.4) for UC (55.2% female); median (range) disease duration (years) was 7.4 (0.6–36.9) for CD and 5 (0.7–33.8) for UC. At enrolment, 51.5% of CD pts had colonic involvement, 32.7% ileocolonic, 8.9% ileal, 1% isolated upper tract and 5.9% had combined L4/other. In UC, 46.2% had extensive colitis, 44.7% left-sided colitis and proctitis 9.1%. 51.6% of CD pts had non-inflammatory behaviour (37.7% stricturing; 13.9% penetrating), and 34% had perianal disease (13.9% as B1p), resulting in a total of 65.5% pts with complicated disease. Only 9.3% of CD (Harvey Bradshaw Index ≥8) and 7.7% of UC (partial Mayo Score ≥5) pts showed moderate-to-severe disease activity at enrolment. In CD, 70.3% of pts were receiving a biologic agent vs. 29.7% of UC pts. Immunosuppressant (IMM) use was similar between groups (CD 39.6%, UC 40.0%); nearly one-third of the pts on a biologic were receiving concomitant IMM (CD 33.8%, UC 34.9%). Aminosalicylates (5-ASA) were used for most UC pts (89.0%) vs. 47.5% of CD pts, mainly in those with L2 disease. 5-ASA monotherapy was prescribed in 32.1% of UC vs. 5.3% of CD pts, but were also used with IMM (UC 25%, CD 11%), biologics (UC 15%, CD 11.6%) or all three therapies combined (UC 6.4%, CD 17.9%). Corticosteroids (CS) were the least prescribed therapy (CD 7.9%, UC 13.8%). IBD treatments ever prescribed during the retrospective period were (CD, UC): biologics: 79.2%, 33.8%; IMM: 65.3%, 58.6%; 5-ASA: 62.4%, 97.9%; CS: 55.4%, 69.7%. Conclusion In this cohort of IBD patients, biologics use was high, especially among CD patients, in line with disease behaviour, and possibly by their increased availability in these reference centres. This study also highlights country-specific clinical features such as the low proportion of CD pts and the high prevalence of colonic involvement in CD.

Abstract Background To facilitate personalised treatment of inflammatory bowel disease (IBD), biomarkers for disease entity and disease severity in easily accessible samples are required. Therefore, we aimed to (i) identify proteins that discriminate Crohn’s disease (CD) from ulcerative colitis (UC), (ii) assess the association of proteomic profiles with disease severity and (iii) assess the potential to use serum samples as a proxy for intestinal biopsies. Methods In this prospective cross-sectional study, IBD patients with active endoscopic disease (presence of ≥1 ulcer (CD) or Mayo score ≥1 (UC)) and age matched non IBD controls (normal endoscopy) were included. In IBD, biopsies were taken from inflamed tissue; in CD from the edge of an ulcer and in UC and controls between 20 and 25 cm from the anal verge. Disease severity was dichotomised in mild vs. severe defined as SES CD <10 vs. ≥11 in CD and Mayo endoscopy score 1/2 vs. 3 in UC. Ninety-two inflammatory proteins were measured in biopsies and serum using a proximity extension assay (OLINK). The elastic net algorithm was used to select proteins associated with disease severity. Multiplicity adjustments were done using the Benjamini–Hochberg approach. Results Forty-one CD, 39 UC and 10 controls were included. Median SES-CD score [IQR] was 9 [7–16] in CD. In UC, 20 (51.3%), 15 (38.5%) and 4 (10.3%) patients had an endoscopic Mayo score of 3, 2 and 1, respectively. Three proteins differed significantly between UC and CD in tissue (IL-17A, IL13 and CCL4). However, this was not reflected in serum levels of these molecules. For prediction of disease severity in CD, elastic net regression identified a set of 11 serum proteins that discriminated mild from severe disease (accuracy 0.667). Top five proteins were IFNγ (OR 3.03), CCL23 (OR 1.28), Cystatin D (OR 0.61), TNF (OR 1.28) and HGF (OR 1.17) (Figure 1). In tissue, no discriminatory profile was identified. Conversely, in serum of UC, no proteins were selected, while a set of three tissue proteins was associated with disease severity (accuracy 0.725). These proteins were osteoprotegerin (OPG) (OR 1.66), IL8 (OR 1.09) and CCL25 (OR 0.97). The discrepancy between serum and tissue was further supported by correlation analyses. Of all 92 proteins, only three showed significant correlation between tissue and serum: IL17A (r = 0.44), TGF-α (r = 0.42) and IL6 (r = 0.39). Conclusion Proteomic profiles between tissue and serum in active IBD correlated poorly. Only in CD, serum markers differentiated mild from severe disease. In UC, no proteins in serum were selected whereas in tissue, expression of OPG, IL-8 and CCL25 was associated with disease severity. These data again emphasise the difference between CD and UC on a molecular level.

Abstract Background: Obesity has gained attention among patients with inflammatory bowel disease (IBD). The impact of visceral obesity on chronic obstipation, inflammation, immune function and cognition after diagnosis of IBD is still unknown.Methods: This is a cross-sectional study of 140 IBD patients. Patients’ visceral adipose tissue (VAT) and subcutaneous adipose tissue (SAT) were measured by abdominal computerized tomography (CT) scans and were grouped according to visceral obesity. Baseline variables, chronic obstipation status, inflammation status and immune function were compared. The implications of visceral obesity on cognitive function were evaluated using Mini-Mental State Examination (MMSE).Results: The prevalence of visceral obesity was 51% (37 out of 72) for CD patients and 26% for UC patients (18 out of 68 patients). CD patients with visceral obesity has higher incidence of chronic obstipation (81% vs. 57%, P = 0.028), higher IL-6 levels (9.3 vs. 6.0 pg/ml, P = 0.045) and lower CD4+ T cells (32.7% vs. 44.0%, P = 0.034). For UC patients, patients with visceral obesity have the tendency of higher IL-6 levels (7.2 vs. 6.0 pg/ml, P = 0.053).Conclusion: IBD patients had high risks of visceral obesity. Patients with visceral obesity had higher prevalence of chronic obstipation, higher inflammation levels, decreased immune function.

Background: The single nucleotide polymorphism (SNP) rs1042058 within the gene locus encoding tumor progression locus 2 (TPL2) has been recently identified as a risk gene for inflammatory bowel disease (IBD). TPL2 has been shown to regulate pro-inflammatory signaling and cytokine secretion, while inhibition of TPL2 decreases intestinal inflammation in vivo. However, the clinical and molecular implications of this disease-associated TPL2 variation in IBD patients have not yet been studied. Methods: We analyzed the impact of the IBD-associated TPL2 variation using clinical data of 2145 genotyped patients from the Swiss IBD Cohort Study (SIBDCS). Furthermore, we assessed the molecular consequences of the TPL2 variation in ulcerative colitis (UC) and Crohn’s disease (CD) patients by real-time PCR and multiplex ELISA of colon biopsies or serum, respectively. Results: We found that presence of the SNP rs1042058 within the TPL2 gene locus results in significantly higher numbers of CD patients suffering from peripheral arthritis. In contrast, UC patients carrying this variant feature a lower risk for intestinal surgery. On a molecular level, the presence of the rs1042058 (GG) IBD-risk polymorphism in TPL2 was associated with decreased mRNA levels of IL-10 in CD patients and decreased levels of IL-18 in the intestine of UC patients. Conclusions: Our data suggest that the presence of the IBD-associated TPL2 variation might indicate a more severe disease course in CD patients. These results reveal a potential therapeutic target and demonstrate the relevance of the IBD-associated TPL2 SNP as a predictive biomarker in IBD.

Abstract Background and Aims There are currently several recruitment challenges in randomized controlled trials (RCTs) for inflammatory bowel disease (IBD), which prolong the drug approval process and affect the generalizability of study results. The purpose of this study is to characterize individuals who participate in IBD RCTs and identify factors that could influence future recruitment strategies. Methods We performed a cross-sectional study within the IBD Partners cohort comparing patients with current or prior participation in an RCT of medical therapy for IBD to those without any RCT participation. Bivariate statistics were used to compare RCT participation by IBD subtype and by other demographic and disease characteristics, and predictive modeling was used to identify factors predictive of RCT participation. We calculated the percent of the cohort that participated in an RCT during each calendar year from 2011 to 2018 and accessed Clinicaltrials.gov to determine the number of active RCTs for IBD therapies per year during that same period. Results A total of 14,747 patients with IBD were included in the analysis and 1116 (7.6%) reported RCT participation at any time. Demographic factors predictive of RCT participation included following at an academic institution [odds ratio (OR) = 1.8; 95% confidence interval (CI) 1.51–2.04) and age 36–75 (OR = 1.7; 95% CI 1.46–1.92). Patients with Crohn’s disease were more likely to participate than those with ulcerative colitis (OR = 1.5; 95% CI 1.35–1.77). Patients with more severe disease were more likely to participate, including those with prior IBD-related hospitalization (OR = 2.6; 95% CI 2.19–2.99), IBD-related surgery (OR = 2.5; 95% CI 2.24–2.87), biologic exposure (OR = 3.2; 95% CI 2.76–3.65), and “Poor” or worse quality of life (OR = 1.7; 95% CI 1.45–1.93). Steroid-free remission was associated with a lower likelihood of RCT participation (OR = 0.6; 95% CI 0.53–0.70). Although the number of active RCTs for IBD more than doubled between 2011 and 2018, RCT participation rates during that same time period decreased from 1.1% to 0.7% of the cohort. Conclusions RCT participation declined within this cohort. Groups underrepresented in RCTs for IBD included younger patients, patients followed in community settings, and patients with more mild disease. The non-RCT group had mean disease activity scores that did not meet remission thresholds, demonstrating populations in need of alternate therapies for whom clinical trials could be an option. Given anti-tumor necrosis factor (TNF) exposure rates in this national cohort, studies should focus on anti-TNF failure populations. Investigators should make every effort to offer RCTs to all patients and network with community providers to increase awareness of RCTs.
