Transdermal Estrogen in Women With Anorexia Nervosa: An Exploratory Pilot Study.

ABSTRACT: Anorexia nervosa (AN) is a psychiatric disorder characterized by self-induced starvation, low body weight, and elevated levels of bone marrow adipose tissue (BMAT). BMAT is negatively associated with BMD in AN and more than 85% of women with AN have low bone mass and an increased risk of fracture. Although a majority of women with AN are amenorrheic, which is associated with low BMD, oral contraceptive pills, containing supraphysiologic doses of estrogen, are not effective in increasing bone mass. We performed a 6-month, open-label study of transdermal estradiol (0.045?mg/day)?+?levonorgestrel (0.015?mg/day) in 11 women with AN (mean age?±?SEM: 37.2?±?2.3?years) to investigate the effects of transdermal, physiologic doses of estrogen on BMD and BMAT in women with AN. We measured change in BMD by DXA, change in BMAT at the spine/hip by 1H-magnetic resonance spectroscopy, and change in C-terminal collagen cross-links (CTX), P1NP, osteocalcin, IGF-1, and sclerostin after 3 and 6 months of transdermal estrogen. Lumbar spine (2.0%?±?0.8%; p = 0.033) and lateral spine (3.2%?±?1.1%; p = 0.015) BMD increased after 6 months of transdermal estrogen. Lumbar spine BMAT decreased significantly after 3 months (-13.9?±?6.0%; p = 0.046). Increases in lateral spine BMD were associated with decreases in CTX (p = 0.047). In conclusion, short-term treatment with transdermal, physiologic estrogen increases spine BMD in women with AN. Future studies are needed to assess the long-term efficacy of this treatment. © 2019 The Authors.

Project description:Background: Anorexia nervosa (AN) is a serious and life-threatening psychiatric condition. With a paucity of approved treatments, there is a desperate need for novel treatment avenues to be explored. Here, we present (1) an overview of the ways through which Public Patient Involvement (PPI) has informed a trial of psilocybin-assisted therapy for AN and (2) a protocol for a pilot study of psilocybin-assisted therapy in AN currently underway at Imperial College London. The study aims to assess the feasibility, brain mechanisms and preliminary outcomes of treating anorexia nervosa with psilocybin. Methods: (1) PPI: Across two online focus groups, eleven individuals with lived experience of AN were presented with an overview of the protocol. Their feedback not only identified solutions to possible barriers for future participants, but also helped the research team to better understand the concept of "recovery" from the perspective of those with lived experience. (2) Protocol: Twenty female participants [21-65 years old, body mass index (BMI) 15 kg/m2 or above] will receive three oral doses of psilocybin (up to 25 mg) over a 6-week period delivered in a therapeutic environment and enveloped by psychological preparation and integration. We will work with participant support networks (care teams and an identified support person) throughout and there will be an extended remote follow-up period of 12 months. Our two-fold primary outcomes are (1) psychopathology (Eating Disorder Examination) across the 6-month follow-up and (2) readiness and motivation to engage in recovery (Readiness and Motivation Questionnaire) across the 6-week trial period. Neurophysiological outcome measures will be: (1) functional magnetic resonance imaging (fMRI) brain changes from baseline to 6-week endpoint and (2) post-acute changes in electroencephalography (EEG) activity, including an electrophysiological marker of neuronal plasticity. Discussion: The results of this pilot study will not only shed light on the acceptability, brain mechanisms, and impression of the potential efficacy of psilocybin as an adjunct treatment for AN but will be essential in shaping a subsequent Randomised Control Trial (RCT) that would test this treatment against a suitable control condition. Clinical Trial Registration: identifier: NCT04505189.
