Active clinical trials for "Anorexia"

This study aims to optimize a treatment package for the relapse prevention treatment of AN. In the Preparation Phase, we examined accessibility and feasibility of the treatment package. In the current Optimization Phase, we will identify which components of treatment contribute to positive outcomes after acute hospitalization. We will carefully evaluate maintenance of remission, measured by rate of weight loss and end-of-trial status.

To determine the accuracy of continuous glucose monitoring (CGM) with point of care (POC) fingerstick glucose monitoring and venous blood glucose in patients with eating disorders, specifically anorexia nervosa, restricting subtype (AN-R); avoidant/restrictive food intake disorder (ARFID); and anorexia nervosa, binge/purge subtype (AN-BP).

The goal of this observational study is to compare short and long-term effects of manualised Family Based Treatment for adolescent anorexia nervosa to those of non-manualised family therapy. The study will approach former patients who were treated before and after Family Based Therapy was adopted in an outpatient clinic, and extract data from electronic health records and public registries.

The purpose of this study is to investigate areas of the brain responsible for 'liking', 'wanting', and learning in adults with eating disorders using brain imaging techniques, computer tasks, a test meal, and self-report questionnaires and interviews. The investigators will study changes in brain activity using a procedure called functional magnetic resonance imaging (fMRI). This study will include 252 women with an eating disorder (63 AN-restricting type (AN-R), 63 AN-binge eating/purging type (AN-BP), 63 bulimia nervosa (BN)) and 63 healthy controls (HC) aged 18-39. Aim 1: To examine neural differences in 'liking' and 'wanting' in ED relative to HC. Aim 2: To examine differences in instrumental learning for reward and punishment in ED relative to HC. Aim 3: To examine how 'liking' and 'wanting' drive instrumental learning in ED and predict clinical symptoms at baseline and 1 year later. Exploratory Aim: To explore the associations of dopamine function, as measured by neuromelanin MRI (NM-MRI), with ED diagnosis and brain response to 'liking', 'wanting', and learning.

BACKGROUND: Sudden death due to thromboembolic (TE) events in patients with anorexia nervosa (AN) is well known. However, the incidence of TE events and the hemostatic balance in patients with AN are sparsely investigated. Also, associations between re-nutrition and the hemostatic balance have not been studied. OBJECTIVE: To describe the incidence of TE events in patients with AN compared to the background population, to characterize the hemostatic balance in AN compared to normal-weight women, and to assess the associations between the hemostatic balance and nutritional status, insulin sensitivity and cortisol level in women with AN. METHODS: The incidence of TE will be described using a Danish cohort of AN patients (n=10,049) with follow-up in national registries. A comprehensive battery of hemostatic biomarkers will be compared in a case-control study of 40 patients with AN and associations between hemostasis and nutritional status will be studied.

Anorexia nervosa (AN) is an eating disorder that can lead to severe medical complications. Kidney injuries are unknown in patients with extremely malnourished AN (BMI <13). The primary objective of the study is to evaluate the frequency and to determine the profiles of patients who may develop kidney injuries. The secondary objective is to evaluate the evolution of kidney injuries after a phase of refeeding. Guidelines for medical treatments and dietary intakes will be recommended to avoid severe or irreversible renal disease.

The PROLED study is a prospective and longitudinal study of patients with Eating Disorders. Annual interviews and collection of biological samples are done, as well as during changes in disease course e.g. during hospitalization. Included are qualitative interviews, psychometric tests, questionnaires which are used to collect data on psychopathology. There is also collection of blood, urine and faeces.

The aim of the research project is to investigate the neurological, physiological and behavioral underpinnings associated with the development of anorexia nervosa in adolescents. The goal of the project is to enable new ways to both predict the course of the disease and to influence this process.

Anorexia Nervosa (AN) is a complex and multifactorial psychiatric disease that affects mostly women and is characterized by a self-restriction of food intake leading to life-threatening consequences whose underlying mechanisms are largely unexplored. AN encompasses a constellation of risk factors including genetic, biological, neuro-psychological and social factors. Although AN has a prevalence of only 1-3% in the general population, it has the highest mortality rate amongst any psychiatric disorder. Recovery of normal feeding behaviour in patients often requires several months with a large between-patient variability and a high percentage of relapse, which can occur in 35 to 41% of the patients. There is a huge unmet need for optimal understanding of processes underlying relapse. Reward processing abnormalities represents an important hypothesis underlying AN development and perpetuation. We aim to investigate the mechanisms that contribute to the maintenance and chronicity of the disease after inpatient treatment with a longitudinal design across intensive standardized inpatient treatment. We will challenge our hypothesis through brain imaging, neuropsychological, metabolic and genetic approaches. One hundred twenty-five AN female patients admitted for intensive inpatient treatment will be recruited and evaluated: at admission, after weight recovery and at 6 months after discharge with neurocognitive tests (including the Delay Discounting Task), genetic/epigenetic examination, hormonal blood samples (at each visit and repeated sampling around a meal for a 10-patient subgroup) and brain imaging (including fMRI during a Delay Discounting Task for fifty patients). One hundred healthy controls will be also recruited and be subjected to the same study procedures.

The neuromolecular and metabolic underpinnings of Anorexia Nervosa (AN) are studied using multi-modal molecular (positron emission tomography with two different radioligands) and functional (functional magnetic resonance imaging) neuroimaging in a prospective design. Subjects with AN and normal weight adolescents will be studied with PET and MRI and followed for five years.
