--- _id: '26523' abstract: - lang: eng text: AbstractWith this case report we support our medical hypothesis that metreleptin treatment ameliorates starvation related emotional, cognitive and behavioral symptomatology of anorexia nervosa (AN) and show for the first time strong effects in a male patient with AN. A 15.9 year old adolescent with severe AN of eight-month duration was treated off-label with metreleptin. Hyperactivity was assessed with accelerometry. Visual analogue scales (VAS), validated self- and clinician rating scales and lab results tracked changes from baseline to end of the 24-day dosing period and a five-month follow-up. Substantial improvements of mood and eating disorder related cognitions and hyperactivity set in after two days of treatment. During dosing, sub-physiological testosterone and TT3 levels normalized; clinically libido reemerged. Weight did not increase substantially during the dosing period. During follow-up target weight was attained; mood did not deteriorate; hyperactivity ceased. The results substantiate the strong effects seen in female cases and underscore the need for a double-blind placebo-controlled trial to confirm the observed strong, multiple and rapid onset beneficial effects of metreleptin in AN. author: - first_name: Jochen full_name: Antel, Jochen last_name: Antel - first_name: Susanne full_name: Tan, Susanne last_name: Tan - first_name: Marvin full_name: Grabler, Marvin last_name: Grabler - first_name: Christine full_name: Ludwig, Christine last_name: Ludwig - first_name: Dominik full_name: Lohkemper, Dominik last_name: Lohkemper - first_name: Tim full_name: Brandenburg, Tim last_name: Brandenburg - first_name: Nikolaus full_name: Barth, Nikolaus last_name: Barth - first_name: Anke full_name: Hinney, Anke last_name: Hinney - first_name: Lars full_name: Libuda, Lars id: '88682' last_name: Libuda orcid: 0000-0003-1603-3133 - first_name: Miriam full_name: Remy, Miriam last_name: Remy - first_name: Gabriella full_name: Milos, Gabriella last_name: Milos - first_name: Johannes full_name: Hebebrand, Johannes last_name: Hebebrand citation: ama: Antel J, Tan S, Grabler M, et al.
