The Impact

Inflammatory bowel disease (IBD) is a chronic inflammatory condition of the gastrointestinal (GI) tract with two main clinical types: Crohn's disease, which can affect any part of the GI tract, and ulcerative colitis (UC), which is limited to the colon. While early research focused primarily on the immune dysregulation and genetic susceptibilities associated with IBD, recent groundbreaking technological advances have allowed the investigation of additional factors, including diet and microbial exposures, in the onset and severity of disease. Advances in high-throughput microbial sequencing, anaerobic bacterial culturing techniques and generating germ-free mouse models have revolutionized our understanding of the microbial species associated with inflammation. While the long-standing clinical efficacy of antibiotics or surgery for Crohn's disease highlights the potential contribution of the socalled ‘IBD microbiome’ to inflammation, recent seminal studies revealed the impact of IBD-derived gut microbiota on host mucosal and systemic inflammation. This mechanistic understanding of how our ‘microbial organ’ functionally impacts both mucosal and systemic inflammatory pathways will help drive novel diagnostic and therapeutic approaches for IBD.

The Impact

Background and Objectives: Anemia is the most frequent complication of inflammatory bowel diseases. Clinically, anemia can affect important quality-of-life (QoL) components, such as exercise capacity, cognitive function, and the ability to carry out social activities. The disease activity has a significant impact on QoL, mainly due to clinical manifestations, which are more severe during the periods of disease activity. Our aim was to estimate the impact of anemia on QoL in patients with Crohn’s disease. Material and Methods. We made a prospective study on 134 patients with Crohn’s disease (CD) in a Romanian tertiary center. The CD diagnosis was established by colonoscopy and histopathological examination. In particular cases, additional examinations were required (small bowel capsule endoscopy, computed tomography enterography, and magnetic resonance enterography). Anemia was defined according to the World Health Organization’s definition, the activity of the disease was assessed by Crohn’s disease activity index (CDAI) score, and the QoL was evaluated by Inflammatory Bowel Disease Questionnaire 32 (IBDQ 32). Results: 44.8% patient had anemia, statistically related to the activity of the disease and corticoids use. We found a strong association between QoL and disease activity on all four sub-scores: patients with more severe activity had a significantly lower IBDQ (260.38 ± 116.96 vs. 163.85 ± 87.20, p = 0.001) and the presence of anemia (127.03 vs. 148.38, p = 0.001). In multiple regression analyses, both disease activity and anemia had an impact on the QoL. Conclusions: Anemia has high prevalence in the CD in northeastern region of Romania. Anemia was more common in female patients, in patients undergoing corticosteroid treatment, and in those with active disease. Both anemia and disease activity had a strong negative and independent impact on QoL.

AbstractStudies have demonstrated that inflammatory bowel disease (IBD) patients are at an increased risk of developing anxiety and/or depression. IBD patients with depression/anxiety have higher rates of hospitalization and increased disease severity than those without. So far, there is a paucity of data concerning the impact of anxiety/depression on Chinese IBD patients. The aim of this study was to find out the prevalence of symptoms of anxiety/depression in Chinese IBD population and its impact on IBD-related features. This is a cross-sectional study from the southwest China IBD referral center. Eligible participants were divided into those with symptoms of anxiety/depression and those without based on the Hospital Anxiety and Depression Scale (HADS). Demographic data and disease duration, IBD-related surgery, tobacco use, extra-intestinal manifestations, disease activity scores, endoscopic evaluation, laboratory data and current medication use were compared between two groups. A total of 341 IBD patients [221 Crohn’s disease (CD) and 120 ulcerative colitis (UC)] were included. The prevalence of symptoms of anxiety/depression in IBD was 33.1%. CD patients with symptoms of anxiety/depression tended to have higher scores of simple endoscopic scores for Crohn’s disease (SES-CD) (p = 0.0005). UC patients with symptoms of anxiety/depression had a significantly higher Mayo score (p = 0.0017) and ulcerative colitis endoscopic index of severity (UCEIS) (p < 0.0001) than their non-anxiety/depression counterparts. CD-related surgery (p = 0.012) and Crohn's disease activity index (CDAI) (p < 0.0001) were identified as independent risk factors for symptoms of anxiety/depression in CD, while corticosteroid use (p = 0.036) as an independent risk factor for symptoms of anxiety/depression in UC. This study helps our understanding of the prevalence of symptoms of anxiety/depression in IBD patients and its impact on IBD course and reminds us to pay more attention on IBD management with anxiety/depression.

Abstract Background Women with inflammatory bowel disease (IBD) have an increased risk of postpartum disease activity. We aimed to systematically determine the effect of various risk factors on postpartum IBD disease activity. Methods Electronic databases were searched through January 2021 for studies that reported risk of postpartum disease activity in women with IBD. Pooled odds ratios (ORs) with 95% confidence intervals (CIs) were calculated for the impact of IBD phenotype, disease activity, therapy de-escalation, mode of delivery, and breastfeeding on postpartum disease activity. Study bias was determined using the Quality in Prognostic Studies tool. Results Twenty-seven observational studies (3825 patients) were included, 15 of which had a high risk of confounding bias. The pooled incidence of women with postpartum active IBD was 31.9% (95% CI, 25.6–38.1). Similar results were seen with ulcerative colitis and Crohn’s disease (CD; OR, 0.96; 95% CI, 0.58–1.59). Those with stricturing (OR, 3.64; 95% CI, 1.31–10.08) and penetrating (OR, 4.25; 95% CI, 1.11–16.26) CD had higher odds of postpartum active IBD. Active disease at conception (OR, 10.59; 95% CI, 1.48–76.02) and during pregnancy (OR, 4.91; 95% CI, 1.82–13.23) increased the odds of postpartum disease activity. Similarly, biologic discontinuation in the third trimester (OR, 1.77; 95% CI, 1.01–3.10) and therapy de-escalation after delivery (OR, 7.36; 95% CI, 3.38–16.0) was associated with postpartum disease activity. Conclusions Complicated Crohn’s disease, disease activity at conception and during pregnancy, and de-escalation of biologics during pregnancy or after delivery are associated with postpartum disease activity in women with IBD.

Leukocyte Imaging

A prospective study was initiated to compare the clinically proven results concerning localization/extent and activity of inflammatory bowel diseases with those of 111ln-oxine leukocyte imaging. All patients studied were completely examined with barium enema x-ray, clinical and laboratory investigations, and endoscopy with histopathology. A total of 31 leukocyte scans were performed in 15 patients (12 with Crohn’s disease, 3 with ulcerative colitis). The scans were graded by comparing the cell uptake of a lesion (when present) and a bone marrow area providing a count ratio (CR). The inflammatory lesions were correctly localized on 26 leukocyte scans, and in 21 scans the scintigraphically estimated extent of disease was identical to endoscopy. In 5 cases the disease extent was underestimated, 4 scans in patients with relapse of Crohn’s disease were falsely negative, and in one patient with remission truly negative. The scintigraphically assessed disease activity was also in a good agreement with clinical disease activity based on histopathology in all cases. We conclude that leukocyte imaging provides valuable information about localization and activity of inflammatory bowel disease.

Inflammatory Bowel

The incidence, prevalence, and cost of care associated with diagnosis and management of inflammatory bowel disease are on the rise. The role of gut microbiota in the causation of Crohn's disease and ulcerative colitis has not been established yet. Nevertheless, several animal models and human studies point towards the association. Targeting intestinal dysbiosis for remission induction, maintenance, and relapse prevention is an attractive treatment approach with minimal adverse effects. However, the data is still conflicting. The purpose of this article is to provide the most comprehensive and updated review on the utility of prebiotics and probiotics in the management of active Crohn’s disease and ulcerative colitis/pouchitis and their role in the remission induction, maintenance, and relapse prevention. A thorough literature review was performed on PubMed, Ovid Medline, and EMBASE using the terms “prebiotics AND ulcerative colitis”, “probiotics AND ulcerative colitis”, “prebiotics AND Crohn's disease”, “probiotics AND Crohn's disease”, “probiotics AND acute pouchitis”, “probiotics AND chronic pouchitis” and “prebiotics AND pouchitis”. Observational studies and clinical trials conducted on humans and published in the English language were included. A total of 71 clinical trials evaluating the utility of prebiotics and probiotics in the management of inflammatory bowel disease were reviewed and the findings were summarized. Most of these studies on probiotics evaluated lactobacillus, De Simone Formulation or Escherichia coli Nissle 1917 and there is some evidence supporting these agents for induction and maintenance of remission in ulcerative colitis and prevention of pouchitis relapse with minimal adverse effects. The efficacy of prebiotics such as fructooligosaccharides and Plantago ovata seeds in ulcerative colitis are inconclusive and the data regarding the utility of prebiotics in pouchitis is limited. The results of the clinical trials for remission induction and maintenance in active Crohn's disease or post-operative relapse with probiotics and prebiotics are inadequate and not very convincing. Prebiotics and probiotics are safe, effective and have great therapeutic potential. However, better designed clinical trials in the multicenter setting with a large sample and long duration of intervention are needed to identify the specific strain or combination of probiotics and prebiotics which will be more beneficial and effective in patients with inflammatory bowel disease.

Abstract Background This multicenter prospective study (UMIN000019958) aimed to evaluate the usefulness of serum leucin-rich alpha-2 glycoprotein (LRG) levels in monitoring disease activity in inflammatory bowel disease (IBD). Methods Patients with moderate-to-severe IBD initiated on adalimumab therapy were enrolled herein. Serum LRG, C-reactive protein (CRP), and fecal calprotectin (fCal) levels were measured at week 0, 12, 24, and 52. Colonoscopy was performed at week 0, 12, and 52 for ulcerative colitis (UC), and at week 0, 24, and 52 for Crohn’s disease (CD). Endoscopic activity was assessed using the Simple Endoscopic Score for Crohn’s Disease (SES-CD) for CD and the Mayo endoscopic subscore (MES) for UC. Results A total of 81 patients was enrolled. Serum LRG levels decreased along with improvements in clinical and endoscopic outcomes upon adalimumab treatment (27.4 ± 12.6 μg/ml at week 0, 15.5 ± 7.7 μg/ml at week 12, 15.7 ± 9.6 μg/ml at week 24, and 14.5 ± 6.8 μg/ml at week 52), being correlated with endoscopic activity at each time point (SES-CD: r = 0.391 at week 0, r = 0.563 at week 24, r = 0.697 at week 52; MES: r = 0.534 at week 0, r = 0.429 at week 12, r = 0.335 at week 52). Endoscopic activity better correlated with LRG compared to CRP and fCal on pooled analysis at all time points (SES-CD: LRG: r = 0.636, CRP: r = 0.402, fCal: r = 0.435; MES: LRG: r = 0.568, CRP: 0.389, fCal: r = 0.426). Conclusions Serum LRG is a useful biomarker of endoscopic activity both in CD and UC during the adalimumab treatment.
