Time frame · Baseline (day -1), Post Treatment (day 14) and after 5 weeks Follow Up (day 49)
The Beck Depression Inventory-II is a self-report rating inventory that measures characteristic attitudes and symptoms of depression with 21 items, ranging from 0 (no depressive symptoms) to 3 (strong depressive symptoms). The higher the total score, the more severe the depressive symptoms.
Functional brain connectivity in the metreleptin-assisted therapy group compared to placebo-therapy group between Baseline, Post Treatment and 5 weeks Follow Up
Time frame · Baseline (day -1), Post Treatment (day 14) and after 5 weeks Follow Up (day 49)
For assessment of intrinsic functional connectivity in the brain, functional MRI images will be acquired for each patient. A region-of-interest analysis and calculating correlations between any pair of two brain regions, obtaining a connectivity matrix, will be done.
Anorexia Nervosa psychopathology assessed by the Eating Disorders Examination Questionnaire (EDE-Q) in the metreleptin-assisted therapy group compared to placebo-therapy group between Baseline, Post Treatment and 5 weeks Follow Up
Time frame · Baseline (day -1), Post Treatment (day 14) and after 5 weeks Follow Up (day 49)
The Eating Disorders Examination Questionnaire (EDE-Q) is the self-report version of the Eating Disorder Examination (EDE). The 22 items on the four subscales of restraint, eating concern, weight concern, and shape concern are used to assess eating disorder-specific characteristics in their current manifestations during the last 28 days. 7-point rating scales are used to assess frequencies from 0 (characteristic was not present) to 6 (characteristic was present every day or to an extreme degree). Six further, non-scale-forming items also measure the frequency of diagnostically relevant core behaviors over the last 28 days. The EDE-Q is evaluated by calculating subscale mean values for the Restraint, Eating Concern, Weight Concern and Shape Concern subscales and a total score. At Baseline, Post Treatment and intermediate measurements, the instruction of EDE-Q will be modified to refer to a shortened shortened observation time (last week).
External rated hyperkinesia assessed by the Structured Inventory for Anorexic and Bulimic Eating Disorders (SIAB, item 42) in the metreleptin-assisted therapy group compared to placebo-therapy group between Baseline, Post Treatment and 5 weeks Follow Up
Time frame · Baseline (day -1), Post Treatment (day 14) and after 5 weeks Follow Up (day 49)
Hyperkinesia will be assessed with only one item (item 42) from the Structured Inventory for Anorexic and Bulimic Eating Disorders (SIAB). This Inventory is used to record the entire spectrum of eating disorder symptoms. Item 42 assesses excessive physical exercise ranging from 0 (no physical exercise) to 4 (very frequent physical exercise).
Subjective hyperkinesia assessed by the Exercise and Eating Disorders Questionnaire (EED) in the metreleptin-assisted therapy group compared to placebo-therapy group between Baseline, Post Treatment and 5 weeks Follow Up
Time frame · Baseline (day -1), Post Treatment (day 14) and after 5 weeks Follow Up (day 49)
The Exercise and Eating Disorders Questionnaire (EED) is a clinically derived, self-report questionnaire. 19 items are used to assess compulsive exercise among eating disorder patients. The 6-point rating scale is used to assess the frequencies (never, rare, sometimes, often, mostly, always) during the last 4 weeks. A higher total score indicates a stronger manifestation of compulsive exercises.
Autism symptoms assessed by the Autism-Spectrum Quotient-short version (AQ-k) in the metreleptin-assisted therapy group compared to placebo-therapy group between Baseline, Post Treatment and 5 weeks Follow Up
Time frame · Baseline (day -1), Post Treatment (day 14) and after 5 weeks Follow Up (day 49)
The Autism-Spectrum Quotient-short version (AQ-k) is a self-assessment tool for screening for autistic disorder. The 10 items represent autistic symptoms and a 4-point response scale is used to assess the agreement (complete agreement, agree more, rather disagree, complete disagreement) to those.
Patient's quality of life by items 1, 2, 5, 6, 7, 10, 17, 19, 20, and 22 from the WHO Quality of Life Questionnaire (WHOQOL-BREF) in the metreleptin-assisted therapy group compared to placebo-therapy between Baseline, Post Treatment and 5 weeks Follow Up
Time frame · Baseline (day -1), Post Treatment (day 14) and after 5 weeks Follow Up (day 49)
The WHO Quality of Life Questionnaire (WHOQOL-BREF) with 26 items is a short form of the WHOQOL-100 and is an instrument for recording subjective quality of life. Items 1, 2, 5, 6, 7, 10, 17, 19, 20, and 22 will be used, ranging from 1 (very dissatisfied/ no agreement) to 5 (very satisfied/fully agreement). A higher total score indicates a increased quality of life.
Visual Analog Scale (VAS) about key Anorexia Nervosa and depression symptoms in the metreleptin-assisted therapy group compared to placebo-therapy group between Baseline, Post Treatment and 5 weeks Follow Up
Time frame · Baseline (day -1), Post Treatment (day 14) and after 5 weeks Follow Up (day 49)
10 items assessing hunger, repetitive thought of food, fear of weight gain, drive for activity, inner tension, feeling full, nausea, feeling fat, depressed mood and feeling tired on a 10-point response scale ranging from 1 (not pronounced symptom) to 10 (strongly pronounced symptom).
Social interaction by the Liebowitz Social Anxiety Scale (LSAS) in the metreleptin-assisted therapy group compared to placebo-therapy group between Baseline, Post Treatment and 5 weeks Follow Up
Time frame · Baseline (day -1), Post Treatment (day 14) and after 5 weeks Follow Up (day 49)
The Liebowitz Social Anxiety Scale is a clinician-administered assessment that measures the fear and avoidance associated with social anxiety. Item 2,3,4,5,8,10,11,12,15 and 19 will be rated on the response scale for avoidance behavior from 1 (never) to 4 (almost always). Higher scores indicating greater severity of social anxiety.
Anhedonia by the Snaith-Hamilton Pleasure Scale (SHAPS-D) in the metreleptin-assisted therapy group compared to placebo-therapy group between Baseline, Post Treatment and 5 weeks Follow Up
Time frame · Baseline (day -1), Post Treatment (day 14) and after 5 weeks Follow Up (day 49)
Anhedonia will be assessed with the german version of the Snaith-Hamilton Pleasure Scale (SHAPS-D) that assesses self-reported anhedonia in psychiatric patients. The respective degree of consent regarding the 14 items on the questionnaire will be rated on a bipolar four-point response scale. For the evaluation, each disagree response ('disagree' or 'strongly disagree') is given 1 point and each agree response is given 0 points. By adding up the points, a higher value indicates a greater degree of anhedonia.
