Active clinical trials for "Anorexia Nervosa"

A technique that has been found to be effective at relieving the physical and psychological symptoms associated with inhibiting emotions and emotional thoughts is written emotional disclosure. The goal of this study is to evaluate the effectiveness of written emotional disclosure on the remediation of eating disorder behaviour, cognitions, and management of emotions.

The purpose of this study is to investigate the potential biological predispositions that contribute to the difficulty patients with anorexia nervosa have in maintaining normal weight.

This study examines the role of anxiety in food intake among patients with AN by measuring caloric intake in a standardized, laboratory meal with alprazolam versus a placebo. Patients will participate in two test meal sessions, one after receiving alprazolam and one after receiving a placebo. Patients will be administered psychological measures of anxiety, mood, and eating behavior. Primary outcomes include caloric intake in a laboratory test meal and pre-meal anxiety levels.

The aim of this study is to evaluate the effect of starvation and recovery in adolescent anorexia nervosa patients in regard to microbiome activity and composition and to elucidate potential connections between weight gain, depression and other comorbidities, further to capture hormone levels and inflammation parameters in a longitudinal design.

The aim of this study was to investigate the difference between electroencephalography (EEG) data and current psychological status of individuals diagnosed with anorexia nervosa (AN) and bulimia nervosa (BN).

In healthy humans, the intestinal mucosa acts as an absorption organ and a defensive barrier preventing the passage of toxic substances from the intestinal lumen to the blood stream. Malnutrition and absence of exogenous luminal nutrients in the gastrointestinal tract profoundly affect small bowel morphology and physiology. Many reports have described alterations of ion and nutrient transport, mucosal atrophy and modifications in the intestinal permeability to macromolecules in cases of prolonged intestinal rest, as in severe starvation. These changes may dampen both the absorptive and the barrier functions of intestinal mucosa. The assessment of intestinal permeability, by measuring the urinary excretion of substances that are not metabolised by human tissues and passively cross the intestinal epithelium, is a reliable and non invasive method to investigate the anatomo-functional integrity of the intestinal mucosa. Previous studies have shown an increase of permeability in malnourished humans . The increase of may also increase the risk for inappropriate passage of food antigens and other noxious substances across the mucosal barrier. To this regard, the enhanced susceptibility of malnourished subjects to systemic infections and postoperative sepsis has long been recognised. Anorexia nervosa is a psychiatric disorder characterised by abnormal eating behaviours aiming to decrease body weight. Typically, women with anorexia nervosa restrict food ingestion up to severe starvation. These behaviours usually lead to malnutrition and a more or less prolonged absence of luminal nutrients in the gastrointestinal tract. Therefore, alterations in the integrity and functioning of intestinal mucosa are likely to occur in this condition. There is no information on intestinal permeability in patients with eating disorders. We hypothesised that, as it occurs in simple starvation and malnutrition, intestinal permeability should be increased in fasted undernourished people with anorexia nervosa and decrease after re feeding. Therefore, in the present study, we explored intestinal permeability of 23 subjects with anorexia nervosa by means of the lactulose-mannitol test and urinary sucralose excretion and compare them to 46 controls. Moreover, auto-antibodies (α-MSH ) have been found in patients with anorexia nervosa. The origin of these auto-antibodies is still unknown , but some studies suggested a digestive origin. Moreover, modifications of intestinal flora have been described in patients with anorexia nervosa. Actually, a study of the intestinal barrier of patients with anorexia nervosa is necessary. In this study, a comparaison of intestinal permeability and autoantibodies (α-MSH) rate is proposed before and after re-feeding in patients with anorexia nervosa.

This study will determine the importance and the level of physical activity among women with anorexia nervosa, both during inpatient treatment and 1 year after hospital discharge.

Anorexia means loss of appetite. But there is disagreement about whether the appetite is changed by the disease anorexia nervosa (AN). Appetite is a subjective essential sense, which is regulated in a complex ensemble between brain, stomach - intestinal system and hormones. As a direct result of malnutrition, there are many somatic complications caused by the disease AN. Several of these complications may in itself affect hunger- and satiety perception. An example of this is delayed gastric emptying. Furthermore, changes in the hormone systems affects the biological "reward system" in the brain, which plays an important role in appetite regulation. There is clearly need for research that could lead to better treatments for AN. Hunger- and satiety perception has only been studied in a few small cross-sectional studies with no clear conclusion. The purpose of the study is to determine whether a visual analog scale measurement can detect changes in hunger- and satiety perception in a least 30 patients admitted to nutrition for life-threatening severe anorexia nervosa. It may lead to the first step in the development of a simple and inexpensive instrument which may prove to be useful in measuring the impact of new and ongoing treatments of the disease.

This study is designed to understand responsiveness to reward in adolescents with restricting-type anorexia nervosa compared with non-clinical controls, and how it is affected by potential-threat perception.

This study focuses on representations of the interior of the body and interoceptive awareness in women with anorexia nervosa in comparison with women without eating disorders.
