Active clinical trials for "Anorexia"

Anorexia nervosa is an eating disorder whose symptomatology induces a modification of the intestinal microbiota. To date, studies have shown variable profiles without linking them to metabolic and neuropsychological energy phenotyping. This intestinal dysbiosis could be involved in the maintenance of the disorders. Bidirectional communication channels exist between the microbiota, the intestine and the brain. Anomalies in these pathways could explain the impact of the microbiota on the pathophysiology of anorexia nervosa. Therapeutic interventions would then be possible to restore the microbiota in anorexia nervosa and influence the treatment of this disease. This study aims to explore the hypothesis of disruption of the microbiota-intestinal-brain axis transversely and measuring the intestinal microbiota, urinary metabolome, biological factors nutritional, immunological and physiological plasma plasma of the intestine, and finally, the psychological dimensions characteristic of anorexia nervosa.

After discharge from inpatient treatment, 30-50% of patients with Anorexia Nervosa require re-hospitalization within 4-12 months. So far, high relapse rates are mostly considered as lack of the patient's compliance and motivation to recover. However in studies, psychological relapse predictors explain only a minor part of the variance in relapse risk. Metabolic phenotyping has clinical value to predict weight course in obese patients and we assume that it could also be clinically relevant in patients with AN. We hypothesize that in patients with a dissipative but not with the thrifty phenotype, positive energy balance during refeeding causes an over proportional rise in energy expenditure, counteracts continuous weight gain during inpatient treatment, and increases relapse risk within one year after discharge. Thus we believe that metabolic phenotype as a biological parameter has prognostic value for the disease course in AN.

The BodyBabe studies aims to evaluate the perceptions that young mothers with anorexia nervosa (active or in remission) have of their own body and of the body of their child. The evaluations are carried out with self-assessment questionnaires and silhouette scales at three time points: D0 (during the stay at the maternity hospital), D15 (15 days after delivery) and M9 (9 months after delivery). The output expected from this study is to validate a questionnaire to help healthcare providers to adapt their care of women with anorexia nervosa during the pregnancy and the post-partum period.

Fibroblast growth factor 23 (FGF23) is a recently discovered phosphaturic hormone produced by osteocytes. It is involved in phosphate-calcium metabolism (via its phosphaturic action and inhibition of 1,25-OH vitamin D). There are no published studies on the role of FGF23 in undernourished anorexic adolescents taking oral phosphorus supplements.

This study investigates excessive avoidance behaviors in patients with a diagnosis of Anorexia Nervosa (AN) compared to a healthy control group. The study further examines the role of reward (relief) as a putative factor in maintaining excessive avoidance behaviors in AN.

The aim of the study are: Retrospectively to study the clinical characteristics and features (somatic, psychological and social variables) of patients treated in Center for Eating Disorders, Odense University Hospital 1994-2004. To study the predictive power of the psychosocial and morphometric data with regard to drop outs, relapse and outcome. To investigate eating habits, social functions and quality of life in weight recovered and chronicly ill patients with eating disorder.

Anorexia nervosa is a serious psychiatric illness whose causes remain poorly understood, and which remains difficult to treat to this day. Many clinical manifestations of this disease can have their origin in abnormalities in the perception of signals coming from inside the body, but this remains to be demonstrated. In recent years, research in healthy subjects has shown how the brain constantly perceives the viscera (heart, lungs, stomach). The examiners will use these new, objective and validated methods to explore how the brain processes information from the viscera (interoception) in anorexic patients. In practice, they will quantify the coupling between the cardiac cycle and involuntary eye movements, as well as between the respiratory cycle and voluntary actions such as pressing a button. Finally, by simultaneously recording the electrical activity of the brain, and that of the stomach, the examiners will measure the coupling between the brain and the stomach. All these measurements, which will be compared between a population of patients and healthy subjects, will make it possible to determine whether anorexic patients have an alteration in the perception of their internal body signals and whether this damage affects several organs.

The objective of this trial is to evaluate gut microbiota changes in undernourished patients with anorexia nervosa under enteral nutrition.

With this investigation, researchers wil look for a link between the appearance of anorexia nervosa and autism spectrum disorders in minors. Previous studies made clear already that patients with anorexia nervosa show elevated characteristics of autism spectrum disorder, when being meassured in adults and in patients in the acute fase of their anorexia nervosa. The purpose of this invenstigation is to see if their is also an elevated incidence of characteristics of autism spectrum disorder in minors with anorexia nervosa in remission.

Background. Decreased taste and smell contribute to loss of appetite (anorexia), and the resulting protein-energy malnutrition increases the frailty of the elderly. The risk of falls, disability, infections and depression often requires them to be institutionalized. Elderly, undernourished and toothless patients often complain about the monotony of a soft, mixed-texture diet. In a previous study, some participants highlighted the pleasure of crunching cookies that have a solid texture that can be eaten in any dental condition. However, the age-related decrease in hearing (presbyacusis) is frequent and progressive from the age of 60. The hypothesis of this work is that older patients may perceive a crunchy food crunching in their mouth, despite presbycusis. If the hypothesis is verified, this would make geriatric caregivers aware of the possibility of diversifying the texture of food, in order to stimulate the pleasure of eating and increase the dietary intake in this population of patients who are often undernourished, dysphagic, edentulous and hearing impaired. The originality of this study is to share the expertise of geriatricians and specialists in mastication/swallowing (dental surgeon, speech-language pathologist), hearing (ENT doctor, hearing care professional) and nutrition (dietician). Type of study. Type of study MR-004 "Research not involving the human person". Protocol. Compare the noise and pleasure of crunching between two hyperprotein nutritional supplements: a soft filled cookie (Nutra Cake™, Délical, France) and a crunchy cookie of the Breton type (Protibis™, Solidages, France). Blind study impossible: each subject will eat a cookie then the other in a random order and will be his own control. The tests will be performed without the possible hearing aids, but with or without the dentures according to the patient's preference. Indeed, some patients have dental prostheses that are no longer suitable for chewing, and that they wear only for aesthetics. Objective. Validate the evaluation criteria "Do you hear the biscuit crunch?" and "Is it a pleasure?" If so, encourage diversification with crunchy foods with a suitable texture, as well as dental and prosthetic rehabilitation of dependent elderly people.
