IL RITARDO DIAGNOSTICO NELLA MALATTIA DI CHRON.
No full textBACKGROUND:
We investigated symptoms and tests performed prior to a formal diagnosis of Crohn's disease and the reasons for diagnostic delay.
METHODS:
Consecutive patients recently diagnosed with Crohn's disease were enrolled between October 2012 and November 2013. Clinical data, symptoms including Rome III criteria at onset and at diagnosis, location and disease phenotype were recorded. Faecal calprotectin, radiological and endoscopic examinations performed prior to diagnosis were analysed. Diagnostic delay, stratified into tertiles and median time, was analysed using parametric and nonparametric tests.
RESULTS:
83 patients (49.4% males, median age 31 years) were enrolled. The median diagnostic delay was 8 (0-324) months. Twenty-six patients did not consult a general practitioner until diagnosis (31.3%), 18 presented to the emergency department (21.7%) and 8 directly to a gastroenterologist (9.6%). Diagnostic delay was not associated with specific symptoms. However, patients with bloating at presentation had a longer delay compared to those who did not (median, 6.1 vs. 16.8 months, respectively; p=0.016). Nineteen patients underwent incomplete ileocolonoscopies (22.9%) and 7 had no biopsies (8.4%), with a consequent diagnostic delay (median, 24 and 24 vs. 6 months, respectively; p=0.025 and p=0.008).
CONCLUSION:
Diagnostic delay for Crohn's disease is significantly associated with incomplete ileocolonoscopies, but not with symptoms, except bloating at presentation
Protein-losing enteropathy in inflammatory bowel diseases
No full textProtein-loosing enteropathy in patients with inflammatory bowel diseases (IBDs) is an uncommon complication, but should be considered in any patient with hypoproteinemia in whom other causes have been excluded such as concomitant hepatic disease, severe malnutrition or proteinuria. The diagnosis is based on determination of fecal alpha-1 antitripsin clearance and stool analysis. Prognosis depends upon the patient and the disease location, severity and complication. Treatment is directed at control of the underlying IBDs but also includes albumin infusion in the most severe cases of hypoalbuminemia and fluid retention, dietary modifications for recovery and maintenance of nutritional status and supportive care to prevent further complication like deep venous thrombosis. Surgery is not curative in Crohn's disease patients, but in severe protein-loosing enteropathy with severe disease, not responding to conventional therapy, it may be the best choice
Long-term outcome of inflammatory bowel diseases with cytomegalovirus colitis : effect of antiviral treatment
No full textObjective The role of cytomegalovirus (CMV) reactivation in the outcome of inflammatory bowel diseases (IBDs) is unclear. Uncertainties remain on the treatment of CMV infection, especially in patients with a viral load just above the normal value in the blood or with very few positive cells in colonic biopsies. This retrospective cohort study reports the long-term outcome of 38 active IBD patients with CMV infection, 13 of whom received an antiviral treatment.
Patients and methods Thirty patients with ulcerative colitis (UC) and eight patients with Crohn's colitis with active colitis and CMV infection, diagnosed by detection of at least one CMV inclusion by histology and immunohistochemistry and/or with the CMV antigen test or the CMV DNA test, were studied. Their clinical history at 6 months and up to 1 year following hospital discharge was reviewed. Clinical remission at hospital discharge and recurrences requiring new treatments or colectomy were considered major outcomes of the study. The features of treated and untreated patients were compared using the Fisher exact test and the Student t-test.
Results All patients showed rare CMV inclusions, and only three had positive blood CMV PCR. Thirteen patients received antiviral treatment, whereas 25 patients did not. No patient underwent colectomy during the hospitalization. The 12-month cumulative rate of clinical relapse requiring new treatment or colectomy was 23% in patients treated with antivirals and 50% in untreated patients (P = 0.165). However, in patients with UC and in those with steroid-dependent/refractory disease, antiviral treatment was associated with a significantly higher clinical remission rate at 12 months (77.8 vs. 45%, P = 0.049, and 77.8 vs. 19.4%, P = 0.038, respectively).
Conclusion In IBD patients with active CMV colitis, antiviral treatment seems to have a marginal impact in the short term, during the treatment of the acute phase, but it may have some beneficial effect in maintaining remission up to 1 year of follow-up in patients with UC and steroid-dependent/refractory disease
New horizons in the imaging of perianal Crohn’s disease: transperineal ultrasonography
No full textIntroduction: perianal disease, most commonly manifest as fistula or abscess formation, affects up to 40% of patients with crohn’s disease. perianal crohn’s disease is disabling, associated with poor outcomes, and represents a therapeutic challenge for physicians. correct diagnosis and classification of perianal disease is the first crucial step for appropriate multidisciplinary management. Areas covered: A literature search was performed of the PubMed database using the terms ‘transperineal ultrasonography’, ‘transperineal ultrasound’, ‘perianal disease’, ‘perianal fistula’, ‘perianal abscess’, ‘magnetic resonance’, ‘endoanal ultrasonography’, ‘endoscopic ultrasound’ in combination with ‘Crohn’s disease’. A comprehensive review of the relative advantages and disadvantages of the various methods of evaluation of perianal Crohn’s disease is provided. A particular focus is placed on transperineal ultrasonography, including historical and technical factors, advantages and limitations, and its current role in practice. An algorithm for integration of transperineal ultrasound into the management of perianal Crohn’s disease into clinical practice is proposed, along with future areas research. Expert commentary: Transperineal ultrasound is a simple, safe, cheap and reliable imaging technique for evaluation of perianal Crohn’s disease, which should be used more frequently in clinical practice
Pre-illness changes in dietary habits and diet as a risk factor for inflammatory bowel disease: A case-control study
No full textAIM: To evaluate whether symptoms of inflammatory bowel disease (IBD), before diagnosis modify dietary habits, and to investigate the pre-illness diet in patients with recent IBD in comparison with an age-matched healthy control group.
METHODS: Overall, 83 new cases of IBD (41 ulcerative colitis, 42 Crohn's disease) and 160 healthy controls were studied. Portions per week of 34 foods and beverages before onset of symptoms were recorded using a validated questionnaire. Duration of symptoms before IBD diagnosis, presence of specific symptoms and their impact on subjective changes in usual dietary habits were also recorded. The association between diet and IBD was investigated by multiple logistic regression and dietary patterns were assessed by factor analysis.
RESULTS: Changes in dietary habits, due to the presence of symptoms, were reported by 38.6% of patients and were not significantly related to specific symptoms, rather to long duration of symptoms, only in Crohn's disease patients. In IBD patients who did not change dietary habits, moderate and high consumption of margarine (OR = 11.8 and OR = 21.37) was associated with ulcerative colitis, whilst high consumption of red meat (OR = 7.8) and high intake of cheese were associated with Crohn's disease.
CONCLUSION: More than one third of IBD patients change dietary habits before diagnosis. Margarine, red meat and cheese increase the risk of ulcerative colitis and Crohn's disease
