Management of ulcerative colitis in a real-life setting: An Italian multicenter, prospective, observational AIGO study.

BACKGROUND: No data are available on the variability in the clinical management of ulcerative colitis (UC) patients by Italian gastroenterologists. Therefore, improving the standards of UC care as provided by the National Welfare Clinical Path (PDTA), in accordance with the European Crohn's and Colitis Organization (ECCO) guidelines for UC, is not easy. AIMS: To assess the management of UC by Italian gastroenterologists in a real-life setting taking into account its variability. METHODS: This prospective, cross-sectional, observational study included IBD-specialized gastroenterologists (GSIBDs) and general gastroenterologists (GGs) working in Italian public hospital units. Consecutive patients with an UC flare were enrolled and the medical treatment evaluated. For each center, the physician in charge of the study (16 GSIBDs and 10 GGs) was administered two electronic questionnaires. RESULTS: Among 26 units, 573 UC patients were enrolled. Good adherence to the European guidelines was reported; GSIBDs reported greater adherence than GGs with a higher prescription of rectal and combination therapy in mild to moderate distal disease and a higher rate of hospitalization in severe UC. CONCLUSION: The management of UC by Italian gastroenterologists in clinical practice is good according to the ECCO consensus recommendations, though some discrepancies are present between GSIBDs and GGs.

Inflammatory bowel disease nurse specialists for patients on biological therapies: a nationwide Italian survey.

BACKGROUND: Management of inflammatory bowel disease (IBD) patients requires a multidisciplinary approach. Among the working team, the role of IBD nurse is expected to be particularly relevant when managing patients receiving biological therapies. We performed a survey to assess the presence of IBD nurse in centers where patients were receiving biologics. METHODS: For this Italian nationwide survey a specific questionnaire was prepared. IBD nurse was defined as a nurse directly involved in all phases of biological therapy, from pre-therapy screening, administration and monitoring during therapy, to follow up performed by a dedicated helpline, completed a specific training on biological therapy therapy, and observed international guidelines. RESULTS: A total of 53 Italian IBD centers participated in the survey, and 91 valid questionnaires were collected. Overall, 34 (37.4%) nurses could be classified as IBD specialists. IBD nurses had a significantly higher educational level than other nurses, they were more frequently operating in Central or Southern than in Northern Italy, they were working in an Academic center rather than in a General hospital, and in IBD centers with >25 patients on biological therapy. On the contrary, mean age, gender distribution, years of nursing, and years working in the IBD unit did not significantly differ between IBD and other nurses. CONCLUSIONS: Our nationwide survey showed that the presence of an IBD nurse is still lacking in the majority of Italian IBD centers where patients receive biological therapies, suggesting a prompt implementation.

Undernutrition, risk of malnutrition and obesity in gastroenterological patients: A multicenter study.

AIM: To investigate the prevalence of undernutrition, risk of malnutrition and obesity in the Italian gastroenterological population. METHODS: The Italian Hospital Gastroenterology Association conducted an observational, cross-sectional multicenter study. Weight, weight loss, and body mass index were evaluated. Undernutrition was defined as unintentional weight loss > 10% in the last three-six months. Values of Malnutrition Universal Screening Tool (MUST) > 2, NRS-2002 > 3, and Mini Nutritional Assessment (MNA) from 17 to 25 identified risk of malnutrition in outpatients, inpatients and elderly patients, respectively. A body mass index ≥ 30 indicated obesity. Gastrointestinal pathologies were categorized into acute, chronic and neoplastic diseases. RESULTS: A total of 513 patients participated in the study. The prevalence of undernutrition was 4.6% in outpatients and 19.6% in inpatients. Moreover, undernutrition was present in 4.3% of the gastrointestinal patients with chronic disease, 11.0% of those with acute disease, and 17.6% of those with cancer. The risk of malnutrition increased progressively and significantly in chronic, acute and neoplastic gastrointestinal diseases in inpatients and the elderly population. Logistical regression analysis confirmed that cancer was a risk factor for undernutrition (OR = 2.7; 95%CI: 1.2-6.44, P = 0.02). Obesity and overweight were more frequent in outpatients. CONCLUSION: More than 63% of outpatients and 80% of inpatients in gastroenterological centers suffered from significant changes in body composition and required specific nutritional competence and treatment.

Leonardo da Vinci meets celiac disease.

BACKGROUND AND AIM: Leonardo da Vinci's face symmetry derives from 3 equal craniofacial segments: trichion-nasion (tn), which represents the superior third of the face, nasion-subnasal (ns) that is the medium third of the face, and subnasal-gnathion (sg) that is the length of the lower third of the face. It has been reported that adult subjects with celiac disease (CD) can be identified on the basis of a greater extension of the forehead in comparison to the medium third of the face, with a high tn/ns ratio. The aim of the present study was to investigate the correlation between facial asymmetry and CD in childhood and adulthood. METHODS: We studied 126 biopsy-proven patients with CD (76 children and 50 adults) and 102 healthy controls (43 children and 59 adults). Their faces were photographed; the pictures were edited using a software program to calculate the facial segments. RESULTS: The tn length was significantly different between adult celiac and adult controls (7.43 ± 1.46 cm vs 6.38 ± 1.73 cm, P = 0.001). The cutoff of 6.5 cm tn, derived from receiver operating characteristic curve analysis, identified 43 of 50 patients (sensitivity 86%), but 34 of 59 controls were positive (specificity 54.2%). The positive predictive value was 56%; however, the tn/ns ratio was not significantly different between celiacs and controls. Neither the tn length nor the tn/ns ratio in celiacs correlated to the time of gluten exposure. CONCLUSIONS: Adults, but not children, with celiac disease show a forehead extension significantly greater than controls, but this test's specificity appears too low to be used in the screening of CD.

KIR/HLA combination associated with the risk of complications in celiac disease.

The pathogenesis of celiac disease (CD) is associated with polymorphisms in human leukocyte antigen (HLA) genes; however, compelling evidence suggests that additional non-HLA genes are associated with CD and related complications. The present study investigated whether killer cell immunoglobulin-like receptor (KIR)/HLA gene combinations are associated with CD and its clinical complications in the population of northeast Italy. The study included 61 adults affected by CD: 48 patients were at first diagnosis and 13 patients had CD-related complications (8 with refractory CD and 5 with cancer). Controls were 69 blood donors genotyped for KIR and HLA. Several statistically significant differences emerged between CD patients and blood donors. The results herein presented show that susceptibility to CD with refractory disease or cancer is associated with various genotypes including the 2DS2/2DL2+C1, 2DS3, 3DL1, and 2DL5B genes. In addition, the absence of the Bw4 ligand may be a predisposing factor for cancer. These results suggest that a KIR haplotype and HLA ligands may be involved in the susceptibility to important clinical CD complications such as tumors or refractoriness as a result of a gluten-free diet.

Diagnostic value of faecal calprotectin in unselected outpatients referred for colonoscopy: A multicenter prospective study.

OBJECTIVES: To evaluate the role of faecal calprotectin in consecutive outpatients referred for colonoscopy. METHODS: Outpatients undergoing colonoscopy at five participating institutions were eligible. Demographic and clinical data were collected. Faecal samples were tested at a single laboratory by means of a commercially available kit. RESULTS: We consecutively enrolled 870 patients. Mean levels of calprotectin were significantly higher in patients with neoplastic and inflammatory disorders when compared with subjects with a normal colonoscopy or trivial endoscopic findings. Elevated calprotectin levels (>50mg/dl) were detected in 85% of patients with colorectal cancer, and 81% of those with inflammatory conditions but also in 37% of patients with normal or trivial endoscopic findings. In patients referred for chronic diarrhoea, sensitivity and negative predictive value were 100% in detecting either any organic colonic disease. In patients referred for symptoms of "suspected functional origin" sensitivity and negative predictive value for colorectal cancer were also 100%. CONCLUSIONS: In unselected outpatients referred for colonoscopy, a single measurement of faecal calprotectin is not sufficiently accurate to identify those with significant colorectal disease. However, a normal result can help rule out organic disease among patients with diarrhoea and those with abdominal pain and/or constipation.
