Nutritional status and bioelectrical phase angle assessment in adult Crohn disease patients receiving anti-TNFα therapy.

BACKGROUND: Altered body composition is frequently observed in Crohn's disease (CD) patients. AIMS: To investigate the nutritional status, and the effect of different therapeutic regimes in adult CD patients. METHODS: Fat free mass (FFM) and BIA-derived phase angle (PhA) were assessed in 45 CD patients, 22 on conventional therapy (CT) and 23 on maintenance therapy with infliximab (MT). Nutritional status was also assessed in 12 CD patients before and following the induction protocol with infliximab. BIA data of CD patients were compared with those of 20 healthy asymptomatic volunteers. In CD patients C Reactive Protein (CRP) and albuminaemia dosage were obtained. RESULTS: The mean values of PhA and of FFM were significantly lower in CT patients when compared with control group and MT patients. Following infliximab treatment FFM increased, although not significantly, while mean phase angle value significantly increased from 4.6±0.3 to 6.2±0.4 (p<0.05). CRP was significantly lower in MT patients compared to that in CT patients. CONCLUSION: CD patients on conventional therapy showed a lower FFM and a lower mean phase angle score compared to those on infliximab therapy. Following infliximab treatment the mean phase angle score normalized. PhA is a reliable nutritional indicator in IBD patients and could be considered as an additional tool for assessing response to treatment.

Surgical and nonsurgical hospitalization rates and charges for patients with ulcerative colitis in Italy: a 10-year cohort study.

BACKGROUND: Today we are observing an increasing incidence of ulcerative colitis associated with an improved survival of patients. AIM: To analyse current rates, outcomes, and costs of inpatient care for ulcerative colitis patients of central Italy. METHODS: The cohort included 644 ulcerative colitis patients, living in the Lazio region, with diagnosis made or confirmed by the staff of a single tertiary referral centre in Rome (1997-2006). Follow-up data on hospitalization rates, costs, and colectomy rates were collected from the Regional Hospital Information System. RESULTS: Overall hospitalization rates were 3 times higher than those of the region's general population, reflecting excess admissions for digestive or infectious diseases (standardized hospitalizations rates for digestive-tract: 15.9; for infectious diseases: 3.5). The overall cumulative risk for colectomy was 7.5%. On the average, hospitalizations for ulcerative colitis lasted 10 days. The mean reimbursement for a ulcerative colitis-related hospitalization was EUR 5120 (€4609 for nonsurgical admissions, €8655 for surgical hospitalizations). CONCLUSION: Ulcerative colitis patients are 3 times more likely to be hospitalized than the general population. Colectomy rates in Italian ulcerative colitis patients resemble those of northern Europe, but most hospital admissions are for diagnostic procedures or medical therapy. Hospitalizations are almost twice as long as those reported in the United States although their mean cost is considerably lower.
