Costs of Crohn's Disease According to Severity States in France: A Prospective Observational Study and Statistical Modeling over 10 Years.
BACKGROUND: To describe the medico-economic characteristics of Crohn's disease (CD), we implemented a multicenter study in France. METHODS: From 2004 to 2006, disease severity states, direct (hospital and extra hospital) and indirect costs were prospectively collected over 1 year in patients with CD naive from anti-tumor necrosis factor alpha (infliximab) at inclusion. Economic valorization was performed from the French Social Insurance perspective, and a statistical modeling over 10 years was performed. RESULTS: In 341 patients, the mean total costs of management were &OV0556;6024 per year (&OV0556;4675 for direct costs). As compared to patients in remission, costs were 4 to 6 times higher in patients in an active period and 19 times higher for patients requiring surgery (SURG). The most important expense items were medical and surgical hospitalizations (56% of total costs), including cost of infliximab (36% of hospitalization costs, i.e., 20% of total costs), indirect costs (22%), and drugs (11%). The statistical modeling over 10 years showed that most of the clinical course was spent in drug-responsive state (54%) with 26% of costs or in remission (32%) with 11% of costs; time spent in a SURG state was small (3.2%) but generated 48% of total costs. CONCLUSIONS: Before the introduction of self-injectable anti-tumor necrosis factor alpha, the most important expenses were supported by hospitalizations, explaining why the most costly states were for patients requiring SURG or dependent on inhospital administrated drugs. Projected data show that most time is spent in a stabilized state with appropriate treatments or in remission, and that costs associated with SURG are high

An Enteral Leucine Supply Modulates Human Duodenal Mucosal Proteome and Decreases the Expression of Enzymes Involved in Fatty Acid Beta-Oxidation
Leucine is well known to regulate protein metabolism in muscle. We recently reported that enteral leucine infusion decreased proteasome activity in human duodenal mucosa and enhanced intestinal cell proliferation, but its effects on gut proteome remain unknown. Therefore, we aimed to assess the effects of an enteral leucine infusion on the whole proteome of duodenal mucosa. In this work, 5 healthy volunteers received for 5h, on 2 occasions and in random order, an enteral supply of maltodextrins (0.25 g kg(-1) h(-1)) or maltodextrins supplemented with leucine (0.035 g kg(-1) h(-1)). At the end of infusion, endoscopic duodenal biopsy samples were collected and analyzed by 2D-PAGE. Eleven protein spots were differentially and significantly (P<0.05) expressed in response to the leucine-supplemented maltodextrins compared with maltodextrins alone. Forty percent of identified proteins by mass spectrometry were located in mitochondria. Four proteins were involved in lipid metabolism: HADHA, ACADVL and CPT2 expressions were reduced, whereas FABP1 expression was increased. In addition, the expression of DHA kinase involved in glycerol metabolism was also downregulated. Finally, leucine supplementation altered the duodenal mucosal proteome by regulating the expression of several enzymes mainly involved in lipid metabolism. These results suggest that leucine supplementation may slowdown fatty acid beta-oxidation in human duodenal mucosa
S1334a Glutamine Combined with Arginine Decrease Gut Inflammation in Biopsies from Patients with Active Colonic Crohn's Disease
Double stenting of oesophagus and airways in palliative treatment of patients with oesophageal cancer is efficient but associated with a high morbidity.
International audienceBACKGROUND: Double stenting of oesophagus and airways may be required in palliative treatment of patients with locally advanced oesophageal cancer. AIM: To assess feasibility, efficacy and complications occurring in patients with locally advanced oesophageal cancer receiving both oesophagus and airways stenting. METHODS: In one single centre between 1997 and 2005, among 180 patients with locally advanced oesophageal cancer treated by the palliative placement of a self-expanding metal stent, patients requiring double stenting of oesophagus and airways were identified. Clinical efficacy, complications and survival were retrospectively collected. RESULTS: Fifteen patients (8.3% of 180) required a double stenting at follow-up. Symptomatic efficacy of oesophagus and airways stenting was 86.7% for dysphagia and 100% for dyspnoea. Median survival after the second stent insertion was 99 days. Life-threatening early complications occurred in three patients after double stenting (20%), including two deaths following oesophageal perforation and massive haemoptysis, respectively. Procedure-related mortality was 13.3%. CONCLUSIONS: Double stenting of oesophagus and airways is feasible in patients with locally advanced oesophageal cancer, with a relevant clinical efficacy. However, early major complications including procedure-related death may occur in as many as 20% of patients. This treatment should be reserved to very selected patients with severe symptoms and end-stage disease
Effects of an Enteral Glucose Supply on Protein Synthesis, Proteolytic Pathways, and Proteome in Human Duodenal Mucosa
BACKGROUND: Previous studies have shown that the glucose supply reduces postoperative insulin resistance and improves patient outcomes. However, the effects of luminal glucose on intestinal mucosal proteins remain unknown. OBJECTIVE: We aimed to assess the effects of an enteral glucose supply on protein synthesis, proteolytic pathways, and proteome in human duodenal mucosa. DESIGN: Twenty healthy volunteers received a 5-h enteral infusion of either saline or glucose (0.12 g · kg(-1) · h(-1)). Simultaneously, a continuous intravenous infusion of l-[1-(13)C]leucine (12 μmol · kg(-1) · h(-1)) was maintained until endoscopy. The duodenal mucosal protein fractional synthesis rate (FSR) was calculated from leucine enrichments assessed in protein and free amino acid pools by gas chromatography-mass spectrometry. Cathepsin D, calpains, and chymotrypsin-like proteasome mucosal activities were evaluated by using specific fluorogenic substrates. A 2-dimensional PAGE-based comparative proteomics analysis was also performed on additional duodenal mucosal biopsy samples to identify differentially expressed proteins. RESULTS: Duodenal mucosal protein FSR and protease activities were not affected by glucose infusion relative to saline. Nevertheless, the comparative proteomics analysis indicated that 10 protein spots were significantly differentially expressed (ie, at least ±1.5-fold modulated; Student's t test, P < 0.05) in response to the glucose infusion relative to saline. Of the 8 proteins identified by mass spectrometry, α-enolase, cytoplasmic aconitate hydratase, and glutathione S-transferase ω-1 were upregulated, whereas epoxide hydrolase 2 was downregulated. CONCLUSION: Enteral glucose supply affected neither duodenal mucosal protein FSR nor activities of mucosal proteases but altered the duodenal mucosal proteome by modulating the expression of several enzymes involved mainly in carbohydrate and xenobiotic metabolism. This trial is registered at clinicaltrials.gov as NCT00213551
Pregnancy outcome in patients with inflammatory bowel disease treated with thiopurines: cohort from the CESAME Study.
International audienceBACKGROUND AND AIMS: Few studies have been conducted addressing the safety of thiopurine treatment in pregnant women with inflammatory bowel disease (IBD). The aim of this study was to evaluate the pregnancy outcome of women with IBD who have been exposed to thiopurines. METHODS: 215 pregnancies in 204 women were registered and documented in the CESAME cohort between May 2004 and October 2007. Physicians documented the following information from the women: last menstrual date, delivery term, details of pregnancy outcome, prematurity, birth weight and height, congenital abnormalities, medication history during each trimester, smoking history and alcohol ingestion. Data were compared between three groups: women exposed to thiopurines (group A), women receiving a drug other than thiopurines (group B) and women not receiving any medication (group C). RESULTS: Mean age at pregnancy was 28.3 years. 75.7% of the women had Crohn's disease and 21.8% had ulcerative colitis, with a mean disease duration of 6.8 years at inclusion. Of the 215 pregnancies, there were 138 births (142 newborns), and the mean birth weight was 3135 g. There were 86 pregnancies in group A, 84 in group B and 45 in group C. Interrupted pregnancies occurred in 36% of patients enrolled in group A, 33% of patients enrolled in group B, and 40% of patients enrolled in group C; congenital abnormalities arose in 3.6% of group A cases and 7.1% of group B cases. No significant differences were found between the three groups in overall pregnancy outcome. CONCLUSIONS: The results obtained from this cohort indicate that thiopurine use during pregnancy is not associated with increased risks, including congenital abnormalities
