Active clinical trials for "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.

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.

This study evaluated the periodontal status of patients suffering from eating disorders (anorexia nervosa and bulimia nervosa). The work hypothesis is that eating disorder patients have a higher risk for periodontal diseases than non-eating disorder subjects.

Context: Psychiatric disorders (anorexia nervosa, depression, anxiety based school refusal) are a major public health concern in adolescence. Their treatment is a challenge for the families, the health care system and society. The treatment is complex and non-standardized. In clinical practice, the relational dimension between the stakeholders is recognized by all. Nevertheless no study has ever crossed their perspectives about therapeutic alliance in adolescent psychiatry. Objective: to explore, within a qualitative approach, how a therapeutic alliance is established in three different clinical situations according to the adolescents, their parents and their physicians by crossing their perspectives. Methods: This is a national (France) multi-center qualitative study based on 180 semi-structured interviews. Participants (purposively selected until data saturation) came from three different sub-samples: (i) adolescents with anorexia nervosa (N =20) plus their parents (N=20) and their physicians (N=20), (ii) adolescents with depressions (N=20) plus their parents (N=20) and their physicians (N=20), and (iii) adolescents with anxiety-based school refusal (N=20) plus their parents (N=20) and their physicians (N=20). Data are collected through open ended semi structured interviews and independently analyzed with NVivo V.11 software by three researchers according to the principles of Interpretative Phenomenological Analysis.
