Clostridium difficile infection (CDI) is associated with dysbiosis and a higher risk of complications in patients with ulcerative colitis. This study reveals a possible association between CDI, dysbiosis, suppression of methionine synthesis, and increased risk of surgery in Crohn’s disease.

Summary Background: There is an impression mostly from specialty clinics that patients with inflammatory bowel disease (IBD) have an increased risk of venous thromboembolic disorders. Our aim was to determine the incidence of deep venous thrombosis (DVT) and pulmonary embolism (PE) from a population-based database of IBD patients and, to compare the incidence rates to that of an age, gender and geographically matched population control group. Methods: IBD patients identified from the administrative claims data of the universal provincial insurance plan of Manitoba were matched 1:10 to randomly selected members of the general population without IBD by year, age, gender, and postal area of residence using Manitoba Health’s population registry. The incidence of hospitalization for DVT and PE was calculated from hospital discharge abstracts using ICD-9-CM codes 451.1, 453.x for DVT and 415.1x for PE. Rates were calculated based on person-years of follow-up for 1984-1997. Comparisons to the population cohort yielded age-adjusted incidence rate ratios (IRR). Rates were calculated based on person-years of follow-up (Crohn’s disease = 21,340, ulcerative colitis = 19,665) for 1984-1997. Results: In Crohn’s disease the incidence rate of DVT was 31.4/10,000 person-years and of PE was 10.3/10,000 person-years. In ulcerative colitis the incidence rates were 30.0/10,000 person-years for DVT and 19.8/10,000 person-years for PE. The IRR was 4.7 (95% CI, 3.5-6.3) for DVT and 2.9 (1.8-4.7) for PE in Crohn’s disease and 2.8 (2.1-3.7) for DVT and 3.6 (2.5-5.2) for PE, in ulcerative colitis. There were no gender differences for IRR. The highest rates of DVT and PE were seen among patients over 60 years old; however the highest IRR for these events were among patients less than 40 years. Conclusion: IBD patients have a threefold increased risk of developing DVT or PE.

Abstract Background Faecal calprotectin (FC) demonstrates an excellent correlation with endoscopic inflammation. In addition, a treatment-decision algorithm for Crohn’s disease (CD) incorporating FC outperforms and improves 12-month mucosal healing compared with a strategy based on symptoms alone. The aim of this study was to determine whether normalisation of FC (<250 μg/g) within 12-months of diagnosis is associated with a reduction in disease progression in CD. Methods This was a retrospective cohort study performed at a tertiary IBD centre. All incident cases of CD diagnosed between 2005 and 2017 were identified. Patients with an FC measurement of >250 μg/g at diagnosis who also had at least 1 follow-up FC measured within the first 12-months of diagnosis and >12 months of follow-up were included. The primary endpoint was a composite of progression in Montreal disease behaviour (B1 to B2/3 or B2 to B3 or new perianal disease), surgery or hospitalisation. Results A total of 375 patients were included with a median follow-up of 5.3 years (IQR 3.1–7.4). Normalisation of FC (<250 μg/g) within 12 months of diagnosis was confirmed in 43.5% (n = 163/375) of the cohort. On multivariable Cox-proportional hazards regression analysis, individuals who normalised their FC within 12 months of diagnosis had a significantly lower risk of composite disease progression (HR 0.351, 95% CI 0.235–0.523, p < 0.001) (Figure 1). Cumulative rates of composite disease progression were 7.8%, 21.4% and 29.9% in those that normalised their FC vs. 22.8%, 50.7% and 60.5% in those that did not at 2, 5 and 7 years after diagnosis, respectively. In addition, normalisation of FC was the only predictor that remained significant for all the separate progression end-points (progression in Montreal behaviour / new perianal disease: HR 0.250, 95% CI 0.122–0.512, p < 0.001; hospitalisation: HR 0.346, 95% CI 0.217–0.553, p < 0.001; surgery: HR 0.370. 95% CI 0.181–0.755, p = 0.006). The strongest predictor of whether an individual normalised their FC within 12 months was the commencement of a biologic within 3 months of diagnosis (OR 4.288, 95% CI 1.585–11.0601, p = 0.004). Conclusion Normalisation of FC by 12-months of diagnosis is associated with a reduced risk of disease progression in CD. Our data provide strong support for implementation of treat-to-target strategies earlier than previously tested in Crohn’s disease. The immediate implication for healthcare providers and patients is that by ensuring resolution of mucosal inflammation - measured by proxy with faecal calprotectin, and regardless of other variables - within 1 year of diagnosis has a dramatic effect on disease course.

Abstract Background The optimal endoscopic target in early Crohn’s disease (CD) that limits long-term disease complications is unknown. Methods We analysed medical records from patients who had follow-up data since the end of CALM. Patients with Crohn’s disease endoscopic index of severity (CDEIS) scores at the end of CALM were included. The primary outcome was a composite of major adverse outcomes reflecting CD progression: new internal fistula/abscess, stricture, perianal fistula/abscess, CD hospitalisation, or CD surgery since the end of CALM. We compared median CDEIS and per cent improvement from baseline CDEIS. Youden index analysis was used to identify optimal CDEIS cut-off score associated with CD progression. Kaplan–Meier and Cox regression methods were used to compare rates of progression by different CDEIS targets. Multivariable models were adjusted for age, prior surgery, and stricturing behaviour. Results 110 patients with median age 28 (IQR 22–38) years, disease duration 0.2 (0.1–0.5) years, and median follow up of 3.1 (1.9–4.4) years were included. Eleven per cent had a history of stricture, 5.5% history of surgery, and 52% were originally in the tight control arm of the CALM study. Median CDEIS score at end of CALM was 3 (0–5.4) and 32 (29%) patients had disease progression. Baseline median CDEIS score was similar between those with and without progression [10.9 (7.5–15.5) vs. 11.9 (8–17.5)]. Median CDEIS score at the end of CALM was higher among those with progression [1.3 (0–5.1) vs. 4.9 (3–9.1), p < 0.001)]. Patients within higher quartiles of CDEIS score had higher rates of progression over time (Figure 1). Patients without disease progression had a greater median decrease in CDEIS score from baseline to end of CALM [90% (60–100%) vs. 50% (30–80%), p < 0.001]. The optimal CDEIS score cut-off was 2 with sensitivity 84%, specificity 60% and NPV 90% for progression. Patients with CDEIS ≤ 2 had less progression over time compared with patients with > 50% improvement from baseline CDEIS (not reaching CDEIS ≤ 2) and those not meeting either endpoint (Figure 2). On adjusted analysis, CDEIS score ≤ 2 was associated with a decreased risk of progression (aHR 0.23, 95% CI 0.09–0.56). Conclusion In early CD, a CDEIS score ≤ 2 is optimal cut-off associated with a lower risk of disease progression.
