An observational study in Anorexia Nervosa Restricting Type and Anorexia Nervosa (DSM-IV Revised Criteria), sponsored by Maimónides Biomedical Research Institute of Córdoba. Not yet recruiting at 1 site in Spain. Per ClinicalTrials.gov, last updated 2026-11-04.
Sponsored by Maimónides Biomedical Research Institute of Córdoba · Observational
The aim of this observational study is to identify biomarkers in extracellular vesicles associated with medullary adiposity occurring in patients with anorexia nervosa. The main question it aims to answer is:
Can this medullary adiposity be associated with the bone deterioration observed in this population?
Participants will be assessed for body composition and a blood sample will be taken by non-invasive techniques.
469 studies on the registry are indexed under Anorexia Nervosa; 127 are open to participants now.
This study's planned enrollment of 30 is below the median of 78 across 142 observational studies indexed under Anorexia Nervosa.

Counted across the registry records on this site, refreshed daily.
The study population will consist of patients diagnosed with active anorexia nervosa according to DSM-V criteria (AN group), with a clinical history in the Clinical Management Unit of Endocrinology and Nutrition of the HURS, patients recovered from the disease (AN-R group) and healthy population of the same age and gender as the patients in the previous groups (CON group).

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
The American Psychiatric Association’s manual of mental health diagnoses. DSM-5 (2013, revised as DSM-5-TR in 2022) replaced DSM-IV, and some studies still name the older edition. “Meets DSM criteria for …” means diagnosed by that edition’s diagnostic criteria, usually by a clinician in an interview.
Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.
What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.
Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.
Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.
Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.
Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.
