Background and Aims Inflammatory bowel disease [IBD] can impair patients' functional capacity with significant negative effects on their quality of life. Our aim was to determine the impact of IBD diagnosis on fitness levels and to assess the levels of engagement in physical activity and fatigue in IBD patient before and after diagnosis. Methods A prospective multi-centre cross-sectional study was performed. Patients diagnosed with IBD in the previous 18 months were recruited. Inclusion criteria included clinical remission and/or no treatment changes within the previous 6 months. Physical exercise levels were assessed by the Godin score and fatigue levels was assessed by the functional assessment of chronic illness therapy [FACIT] score. Results In total, 158 patients (100 Crohn's disease [CD]) were recruited. Mean age was 35.1 years (95% confidence interval [CI] ± 2.0). Gender distribution was approximately equal [51.3% male]. The Mean Harvey Bradshaw and Simple Clinical Colitis Activity indices were 2.25 [95% CI ± 0.40] and 1.64 [95% CI ± 0.49], respectively. The mean Godin score difference before and after IBD diagnosis was 6.94 [ p = 0.002]. Patients with ulcerative colitis [UC] [41.8%] were more likely than patients with CD [23.0%] to reduce their exercise levels [ p = 0.04]. FACIT scores were lower in patients who had experienced relapses [ p = 0.012] and had severe disease [ p = 0.011]. Approximately one-third of patients reduced their activity level following IBD diagnosis. Conclusions Patients were significantly less physically active after a diagnosis of IBD and this was more apparent in UC. Identification of the risk factors associated with loss of fitness levels would help to address the reduced patient quality of life. [ABSTRACT FROM AUTHOR]

Aim: In patients with non-autoimmune liver disease, anticardiolipin antibody (aCL) production is considered to be an epiphenomenon of liver damage not associated with thrombotic complications. There are sparse reports of [...]

OBJECTIVE: Patients with inflammatory bowel disease (IBD) frequently suffer from thromboembolic events. A recently identified mechanism for thrombophilia, the poor anticoagulant response to activated protein C, has been suggested as one of the leading risk factors for thrombosis. The aim of this study was to evaluate the frequency of thrombophilic abnormalities, including activated protein C-resistance (APCR), in Greek patients with ulcerative colitis (UC) and Crohn's disease (CD). METHODS: Forty-eight patients with UC, 36 with CD, and 61 matched healthy controls (HC) were studied. Cases with presence of lupus anticoagulant, use of anticoagulants or heparin, and pregnancy were excluded. Disease activity in CD was evaluated by use of the Crohns Disease Activity Index (CDAI) score and in UC by the Truelove-Witts grading system. Plasma levels of protein C, free protein S, antithrombin III (AT-III), activated protein C resistance (APCR), and fibrinogen were determined in IBD patients, as well as in HC. All the cases and controls with abnormal APCR were further studied by genetic testing for the factor V Leiden mutation. RESULTS: Mean fibrinogen levels in UC and CD patients were significantly elevated (p < 0.0001), compared with HC. The mean values of free protein S, as well as mean APCR, were significantly lower in UC and CD patients than in the HC (p < 0.0001). Seven (five UC and two CD) of 84 IBD patients (8.3%) and three of the HC (4.9%) had the factor V Leiden mutation. No significant difference was observed for the other thrombophilic parameters. Fibrinogen levels and profound free protein S deficiency were found related to disease activity. CONCLUSIONS: Thrombophilic defects are common in Greek patients with IBD and they could interfere either in the disease manifestation or in the thrombotic complications. [ABSTRACT FROM AUTHOR]

OBJECTIVE: Numerous epidemiological studies have been performed to determine risk factors that might contribute to the development of ulcerative colitis (UC). Recent studies have focused on the role of appendectomy in the disease's pathogenesis. This report aims to review and analyze the degree of evidence from recent published studies. METHODS: Medline and Embase databases were scrutinized for studies published between 1987 and January 1999. Reference lists from published articles, reviews, and abstracts from major gastrointestinal (GI) meetings were also reviewed. All studies specifically designed to evaluate the association between appendectomy and UC were selected. Thirteen studies that satisfied our selection criteria were evaluated by metaanalysis. RESULTS: The 13 case-control studies collectively gathered evidence from 2770 patients with UC and 3352 controls. Combining the results of the individual studies gave an overall odds ratio of 0.307 (95% confidence interval [CI] = 0.249-0.377) in favor of appendectomy (p < 0.0001). This suggests that appendectomy gives a 69% reduction in the risk of developing UC (95% CI = 62%-75%). The test for heterogeneity (of all 13 studies) was not significant (χ² = 16.213, d.f. = 12, p > 0.10). The influence of potential confounding factors (mainly smoking) on these results could be excluded. CONCLUSIONS: The review of the literature and the meta-analysis of the selected studies suggest that the inverse association between appendectomy and UC is strong and consistent. Further studies are needed to establish whether a causal relationship exists. [ABSTRACT FROM AUTHOR]

Patients with inflammatory bowel disease (IBD) frequently suffer from thromboembolic events. Anti-cardiolipin (aCL) antibodies have been shown to be associated with thrombosis. Recently, the antibodies against the anti-cardiolipin cofactor beta2-glycoprotein I (a(beta2)GPI) have been found with higher specificity for thrombosis. The presence of these antibodies was assessed in 128 patients with IBD [83 with ulcerative colitis (UC) and 45 with Crohn's disease (CD)] and 100 healthy controls (blood donors). Patients with UC and CD had a significantly higher prevalence of aCL (18.1% and 15.6%, respectively) than healthy controls (HC) (3%). Eleven IBD patients (8.6%) but no HC had a(beta2)GPI. None of the IBD patients with a history of thrombosis had aCL and only one of them (a UC patient with deep vein thrombosis of the right leg) had a high titer of IgG a(beta2)GPI. In conclusion, these data show that both aCL and a(beta2)GPI are significantly associated with IBD but further studies are needed to determine the significance of our findings.

Recent reports have shown that allele 2 of the IL-1 receptor antagonist (IL-1Ra) gene is over-represented in ulcerative colitis (UC). Healthy individuals carrying allele 2 of this gene have increased production of IL-lRa protein. Since the final outcome of the biological effects of IL-β may depend on the relative proportion of these two cytokines, we have studied if a Taq1 polymorphism in the IL-1β gene, which is relevant to IL-1β protein production, may be involved in the genetic susceptibility to UC and Crohn's disease (CD), in association with the established IL-1Ra gene polymorphism. Polymorphisms in the closely linked genes for IL-1β and IL-1Ra were typed in 100 unrelated Dutch patients with UC, 79 with CD, and 71 healthy controls. The polymorphic regions in exon 5 of the IL-lβ gene and in intron 2 of the IL-1Ra gene, were studied by polymerase chain reaction (PCR)-based methods. The IL-lβ allele frequencies in UC and CD patients did not differ from those in healthy controls. In order to study if the IL-1β gene polymorphism might participate synergistically with the IL-1Ra gene polymorphism in susceptibility to UC and CD, individuals were distributed into carriers and non-carriers of allele 2 of the genes encoding IL-1β and IL-1Ra, in each of the patient groups and controls. Results indicated a significant association of this pair of genes, estimated by the odds ratio (OR) after performing Fisher's exact test, in the UC group (P = 0.023, OR = 2.81), as well as in the CD group (P = 0.01, OR = 3.79). Thus, non-carriers of IL-lβ allele 2 were more often present in the subgroup of patients carrying the IL-1Ra allele 2. By contrast, no association of these alleles was detected in the group of healthy controls (P = 1.00, OR = 0.92). These results suggest that the IL-1β/IL-1Ra allelic cluster may participate in defining the biological basis of predisposition to chronic inflammatory bowel diseases. [ABSTRACT FROM AUTHOR]

Background: Data regarding the clinical outcome of patients with immune checkpoint inhibitor (ICI)-induced colitis are scant. We aimed to describe the 12-month clinical outcome of patients with ICI-induced colitis., Materials and Methods: This was a retrospective, European, multicentre study. Endoscopy/histology-proven ICI-induced colitis patients were enrolled. The 12-month clinical remission rate, defined as a Common Terminology Criteria for Adverse Events diarrhoea grade of 0-1, and the correlates of 12-month remission were assessed., Results: Ninety-six patients [male:female ratio 1.5:1; median age 65 years, interquartile range (IQR) 55.5-71.5 years] were included. Lung cancer (41, 42.7%) and melanoma (30, 31.2%) were the most common cancers. ICI-related gastrointestinal symptoms occurred at a median time of 4 months (IQR 2-7 months). An inflammatory bowel disease (IBD)-like pattern was present in 74 patients (77.1%) [35 (47.3%) ulcerative colitis (UC)-like, 11 (14.9%) Crohn's disease (CD)-like, 28 (37.8%) IBD-like unclassified], while microscopic colitis was present in 19 patients (19.8%). As a first line, systemic steroids were the most prescribed drugs (65, 67.7%). The 12-month clinical remission rate was 47.7 per 100 person-years [95% confidence interval (CI) 33.5-67.8). ICI was discontinued due to colitis in 66 patients (79.5%). A CD-like pattern was associated with remission failure (hazard ratio 3.84, 95% CI 1.16-12.69). Having histopathological signs of microscopic colitis (P = 0.049) and microscopic versus UC-/CD-like colitis (P = 0.014) were associated with a better outcome. Discontinuing the ICI was not related to the 12-month remission (P = 0.483). Four patients (3.1%) died from ICI-induced colitis., Conclusions: Patients with IBD-like colitis may need an early and more aggressive treatment. Future studies should focus on how to improve long-term clinical outcomes., (Copyright © 2024 The Author(s). Published by Elsevier Ltd.. All rights reserved.)

Background: Ustekinumab and tofacitinib have recently been approved for the management of moderate to severe ulcerative colitis (UC). However, there is no evidence on how they should be positioned in the therapeutic algorithm. The aim of this study was to compare tofacitinib and ustekinumab as third-line therapies in UC patients in whom anti-TNF and vedolizumab had failed., Methods: This was a multicenter retrospective observational study. The primary outcome was disease progression, defined as the need for steroids, therapy escalation, UC-related hospitalization and/or surgery. Secondary outcomes were clinical remission, normalization of C-reactive protein, endoscopic remission, treatment withdrawal, and adverse events., Results: One-hundred seventeen UC patients were included in the study and followed for a median time of 11.6 months (q 1 -q 3, 5.5-18.7). Overall, 65% of patients were treated with tofacitinib and 35% with ustekinumab. In the entire study cohort, 63 patients (54%) had disease progression during the follow-up period. Treatment with ustekinumab predicted increased risk of disease progression compared to treatment with tofacitinib in Cox regression analysis (HR: 1.93 [95% CI: 1.06-3.50] p = 0.030). Twenty-eight (68%) patients in the ustekinumab group and 35 (46%) in the tofacitinib group had disease progression over the follow-up period (log-rank test, p < 0.054). No significant differences were observed for the secondary outcomes. Six and 22 adverse events occurred in the ustekinumab and tofacitinib groups, respectively (15% vs. 31%, p = 0.11)., Conclusions: Tofacitinib was more efficacious in reducing disease progression than ustekinumab in this cohort of refractory UC patients. However, prospective head-to-head clinical trials are needed as to confirm these data., (© 2023 The Authors.
