Early Atherosclerosis and Acute Vascular Events in Ulcerative Colitis Patients – a Case Series

Introduction: In inflammatory bowel disease uncontrolled inflammation may play a role in the early progression of systemic atheromatosis with increased cardiovascular risk. Endothelial dysfunction is mediated by pro-inflammatory cytokines but also by an increased level of CRP which is involved in the expression of adhesion molecules and atheroma plaque rupture. Tailored treatment with better control of the ulcerative colitis and endoscopic healing might result in decrease risk of atherothrombotic events. Aim: We decided to use a well-established method (vascular Doppler ultrasound with media-intimate index measurement) to detect an increased incidence of endothelial lesions as predictors of early atheromatosis in patients with ulcerative colitis treated with biological or conventional therapy.
Material and methods: We prospectively analyzed 25 patients with RCUH with a mean age of 40 years, 16 with biological treatment. The Student t test, the Mann Whitney U test and the ANOVA test were used to compare continuous variables. Results: A discriminant analysis was performed with the presence of atheroma plaque as a dependent variable and several predictor variables, such as age, triglycerides, cholesterol of patients with ulcerative colitis. Univariate ANOVA analyzes revealed that the presence or absence of atheroma plaque differs in the variables predicting the age, INR and ecoIMT of patients with ulcerative colitis (in the age of patients (F = 8.511, degrees of freedom = 11, p = 0.014) Patients‚ INR (F = 50,437, degrees of freedom = 11, p = 0.001) and Patients’ ecoIMT (F = 7,398, degrees of freedom = 11, p = 0.020) In another analysis of discriminatory function s -introduced the predictor variables specific to measuring the evolution of ulcerative colitis, respectively Mayo and Mayo E (age (F = 0.8511, degrees of freedom = 11, p = 0.014), INR (F = 50.437, degrees of freedom = 11, p = 0.001), ecoIMT (F = 7.398, df = 11, p = 0.020) and Mayo (F = 14.885, degrees of freedom = 11, p = 0.003).

Conclusions: Age, endoscopic activity, and INR were correlated with predictive ultrasound changes for atheromatosis. Strengths are the prospective nature of the study and weaknesses are the limited number of patients and the fact that most patients were in remission and treated with biologicals, which could create bias in the sense of reducing the atherosclerotic risk directly correlated with active inflammation.

Echo Intima-Media Thickness (IMT) in the Evaluation of Early Atherosclerosis in Inflammatory Bowel Disease (IBD) Patients – a Prospective Study

Introduction: Inflammatory bowel diseases (IBD) are accompanied by an early and accelerated atherosclerotic process. Previous studies showed that Doppler ultrasonography and intima-media thickness (IMT) is a reliable marker for early atherosclerosis diagnosis. The aim of our study was to evaluate the presence of early atherosclerosis in a group of subjects with inflammatory bowel diseases, using Doppler ultrasonography and intima-media thickness (IMT) as a marker of subclinical atherosclerosis. Methods: A case-control study was conducted on 61 patients with inflammatory bowel disease and 19 healthy individuals. The included patients had an established IBD diagnosis, based on clinical, endoscopic, and histological criteria for at least 12 months. Results: In our study echo IMT was not significantly higher in IBD patients than in matched healthy controls. We found no difference between Crohn’s disease and ulcerative colitis patients or between conventional or biologic treatment regarding the echo IMT. Severity of the disease and its duration were predictors of an increased IMT. We found that disease activity (measured by the endoscopic scores and CRP) correlates with higher values of echo IMT. Also the presence of anemia reached statistical significance and was correlated with increased echo IMT in the biologic treatment group. Conclusions: In our study we found an increased echo IMT in IBD patients versus control, but the values did not reach statistical significance. We found no difference between Crohn’s disease and UC, conventional or biologic treatment. Age and duration of disease were corelated with increased IMT. Disease that was not controlled (high endoscopic, clinical and biological markers of activity) was correlated with increased echo IMT. The limitations of our study are that in our patients therapy was started early in the course of the disease and that the majority of the patients were in remission when echography was made. Further studies are necessary to evaluate factors correlated with early atherosclerosis in IBD and how echo IMT can be used as a tool in the proactive evaluation of these patients.

Quality of Care in Inflammatory Bowel Disease: the Role of Steroid Assessment Tool (SAT) - a Review

Corticosteroids have an important role in induction of remission in inflammatory bowel disease, but they are not an indicated for maintenance treatment as they are associated with many side effects. Despite new efficient therapeutic options for maintaining remission, there is an excess in prescribing steroids in inflammatory bowel disease. Corticosteroid use was evaluated in international cohorts given that steroid free remission and avoiding serious side-effects of corticosteroids is a desirable goal. We discuss the role and the evidences on a secure web-based steroid assessment tool (SAT) which can be used as an instrument of evaluation of corticosteroid use, a quality indicator in inflammatory bowel disease.
