Abstract

Summary: Background & aims: The main role of the small intestine to absorb the bulk of dietary nutrients, including proteins and amino acids (AA). Enterocytes have long been considered a major player in amino acid homeostasis, especially the glutamine–citrulline–arginine crossroads. In vivo intestinal epithelium cell lines for studies of nitrogen metabolism have now reached their limitations. To push research forward, an interesting approach could be to use the explant incubation model of intestinal tissue, involving in vitro incubation of duodenal tissue biopsy specimens taken from human subjects. Methods: Eight duodenal biopsies were taken during endoscopy from patients without proven intestinal disease. Each biopsy was incubated in complete culture medium for 23 h then weighed, and cell viability was evaluated after 6 and 18 h. We then explored L-citrulline (L-CIT) production (reflecting metabolic activity) and the presence of the main enzymes involved in AA metabolism in the intestine (arginase II, glutaminase I, ornithine aminotransferase, and ornithine carbamoyltransferase). Results: Mean weight of biopsies was 12.36 ± 1.00 mg. Mortality was around 20% after 6 h and 50% after 18 h of incubation. CIT was amply produced by the biopsies, and enzymes implicated in intestinal AA metabolism were expressed in this model. Conclusions: This in vitro explant model of intestinal tissue emerges as a reliable model for conducting ex vivo investigations on AA metabolism.

Abstract

International audience; Background: In recent years, an increasing prevalence of obesity in inflammatory bowel disease (IBD) has been observed. However, only a few studies have focused on the impact of overweight and obesity on IBD-related disability.Aims: To identify the factors associated with obese and overweight patients with IBD, including IBD-related disability.Patients and methods: In this cross-sectional study, we included 1704 consecutive patients with IBD in 42 centres affiliated with the Groupe d'Etude Therapeutique des Affections Inflammatoires du tube Digestif (GETAID) using a 4-page questionnaire. Factors associated with obesity and overweight were assessed using univariate and multivariate analyses (odds ratios (ORs) are provided with 95% confidence intervals).Results: The prevalence rates of overweight and obesity were 24.1% and 12.2%, respectively. Multivariable analyses were stratified by age, sex, type of IBD, clinical remission and age at diagnosis of IBD. Overweight was significantly associated with male sex (OR = 0.52, 95% CI [0.39-0.68], p < 0.001), age (OR = 1.02, 95% CI [1.01-1.03], p < 0.001) and body image subscore (OR = 1.15, 95% CI [1.10-1.20], p < 0.001) (Table 2). Obesity was significantly associated with age (OR = 1.03, 95% CI [1.02-1.04], p < 0.001), joint pain subscore (OR = 1.08, 95% CI [1.02-1.14], p < 0.001) and body image subscore (OR = 1.25, 95% CI [1.19-1.32], p < 0.001) (Table 3).Conclusion: The increasing prevalence of overweight and obesity in patients with IBD is associated with age and poorer body image. A holistic approach to IBD patient care should be encouraged to improve IBD-related disability and to prevent rheumatological and cardiovascular complications.

Abstract

Intensive care unit patients and chronic airway inflammatory disease are characterized by chronic systemic hypoxia and inflammation inducing a decrease in nitric oxide release due to impaired l-arginine (ARG) homeostasis. As ARG is synthesized from circulating l-citrulline (CIT), an alteration of CIT production in small intestine by ornithine carbamoyltransferase could be involved. Here, we posit that hypoxia and/or inflammation has effects on ornithine carbamoyltransferase regulation in enterocytes. A duodenal explant incubation model was used. Biopsy specimens taken from 25 selected patients were incubated for 6 h in 4 groups: control, inflammation, hypoxia, and hypoxia + inflammation. At the end of the incubation period, we measured CIT concentration in culture media, ornithine carbamoyltransferase activity, ornithine carbamoyltransferase protein and gene expression, protein expression of enzymes involved in the CIT production pathway, and expression of energy status proteins. Inflammation and/or hypoxia conditions did not affect CIT production. Ornithine carbamoyltransferase activity was increased in hypoxia conditions (p = 0.023). Expression of enzymes implicated in the CIT crossroads pathway and enzymes reflecting energy status variation was not affected by inflammation and hypoxia. Data sets were pooled to evaluate the variability of the four quartiles for each parameter. CIT production was found to increase over the quartiles whereas other parameters remained stable. Our results showed that intestinal CIT production is preserved during inflammation and/or hypoxia, thus confirming the significance of this metabolic pathway. This suggests that the CIT deficiency observed in clinical hypercatabolic states could be a consequence of high utilization for ARG synthesis.

Abstract

International audience; BACKGROUND: Patients’ experience with healthcare professionals could influence their clinical outcomes. AIMS: To assess inflammatory bowel disease (IBD) patients’ experience with their disease, their treatment and their relationship with their physician. METHODS: A one-week cross-sectional study was conducted in 42 IBD centres. 2011 consecutive outpatients with IBD completed an anonymous self-report questionnaire assessing their experience with and knowledge of IBD. RESULTS: A quantitative assessment of the doctor-patient relationship revealed that patients’ knowledge of IBD and IBD treatment ranged from 7.4 to 8.3 out of 10. In addition to IBD physicians, other sources of information about IBD and current treatment mainly included the internet (80% and 63%, respectively) and general practitioners (61% and 54%). Knowledge about education programmes (28%) was poor, resulting in a lack of willingness to further use these resources (25%). Concerns about IBD treatment were raised in 76% of patients, mostly related to the fear of adverse events (47%) and a lack of efficacy (33%). The need of alternative healthcare professionals was reported by 89% of the sample. CONCLUSION: In a large cohort of patients, we highlighted gaps in the management of patients with IBD regarding the need for higher-quality information and the implementation of alternative healthcare professionals.
