Assessment of Nutritional Status by Bioelectrical Impedance in Adult Patients with Celiac Disease: A Prospective Single-Center Study.

The gluten-free diet [GFD] has been linked to an increased risk of weight gain and the development of metabolic disorders. Most of the studies have focused on the effect of GFD on the Body Mass Index [BMI]. We aimed to evaluate the nutritional status using specific nutritional parameters in patients with celiac disease [CeD] at diagnosis and on a GFD compared to healthy controls. We recruited subjects at our outpatient clinic at the University of Padua. We collected demographic and clinical data and values obtained with bioelectrical impedance analysis. A total of 24 CeD patients and 28 healthy controls were enrolled. CeD patients at diagnosis had a lower body cell mass index [BCMI, p = 0.006], fat-free mass index [FFMI, p = 0.02], appendicular skeletal muscle index [ASMI, p = 0.02], and phase angle [PA] [p < 0.001] compared to controls. Their percentage of extracellular water [ECW] was also higher [p < 0.001]. Considering CeD patients after GFD, nutritional status significantly improved after 6 months of GFD. We did not observe differences in BMI among groups [p = ns]. CeD patients at diagnosis were found to have a poorer nutritional status than healthy controls, with a positive effect of the GFD on their nutritional status, underlining the inefficacy of evaluating this aspect through only BMI evaluation.

Factors associated with disability in patients with ulcerative colitis: A cross-sectional study.

OBJECTIVES: Ulcerative colitis (UC) can give rise to several restrictions of patients' working and social activities. We aimed to determine the association between disease chronicity and the state of disability in a large population with UC. METHODS: We recruited consecutive patients with UC attending the inflammatory bowel disease (IBD) unit of the Azienda Ospedaliera of Padua between July and December 2017. We collected patients' characteristics and clinical information, and all participants completed the IBD questionnaire (IBDQ) for quality of life assessment and the IBD disability index (IBD-DI) questionnaire. Using univariate logistic regression models we assessed whether the patients' characteristics and IBD-related variables were associated with an IBD-DI score ≤3.5. Statistically significant variables in the univariate analyses were then included in a multivariate regression model. Correlations between IBD-DI and all the above mentioned characteristics were investigated using the Spearman's rank correlation coefficient. RESULTS: We included 201 patients. A positive correlation was observed between IBD-DI and IBDQ (r = 0.82, P < 0.001). Multivariate regression modelling identified the following as independent factors related to disability: active disease (partial Mayo score ≥2) (odds ratio [OR] 6.54, 95% CI 3.21-13.22), the presence of extraintestinal manifestations (EIM) (OR 2.48, 95%, CI 1.11-5.54) and occasional alcohol consumption (OR 0.39, 95% CI 0.20-0.76). CONCLUSIONS: Impaired disability is mainly correlated with disease activity, the presence of EIM and no alcohol consumption. Moreover, there is a strong correlation with patients' quality of life. Therefore, in clinical practice, greater awareness of IBD-related disability is needed to better manage patients' outcomes.
