Dehydroepiandrosterone status and efficacy of dehydroepiandrosterone supplementation for bone health in anorexia nervosa: A systematic review and meta-analysis

Anorexia nervosa and adrenal hormones: a systematic review and meta-analysis

OBJECTIVE

Anorexia nervosa is a primary psychiatric disorder characterized by self-induced negative energy balance. A number of hormonal responses and adaptations occur in response to starvation and low body weight including changes in adrenocortical hormones. Our objective was to systematically review adrenocortical hormone levels in anorexia nervosa.

DESIGN/METHODS

We searched MEDLINE and EMBASE for studies that reported at least one adrenocortical hormone, including dehydroepiandrosterone (DHEA), DHEA-sulphate (DHEA-S), progesterone, 17-hydroxyprogesterone, pregnenolone, cortisol (serum, urine, cerebrospinal fluid, and hair sample), aldosterone, androstenedione, and testosterone in patients with anorexia nervosa and normal-weight healthy controls from inception until October 2021. Means and standard deviations for each hormone were extracted from the studies to calculate a mean difference (MD). A pooled MD was then calculated by combining MDs of each study using the random-effects model.

RESULTS

We included a total of 101 studies with over 2500 females with anorexia nervosa. Mean cortisol levels were significantly higher in anorexia nervosa as compared to normal-weight controls for multiple forms of measurement, including morning cortisol, 12-hour and 24-hour pooled serum cortisol, 24-hour urine cortisol, and after an overnight dexamethasone suppression test. In contrast, mean serum total testosterone and DHEA-S levels were significantly lower among patients with anorexia nervosa.

CONCLUSIONS

Women with anorexia nervosa have higher cortisol levels and lower DHEA-S and testosterone levels compared to women without anorexia nervosa. This finding is important to consider when evaluating low-weight women for disorders involving the adrenal axis, especially Cushing's syndrome.

Dehydroepiandrosterone sulfate supplementation in health and diseases

Dehydroepiandrosterone sulfate (DHEAS) is a hormone produced by the zona reticularis of the adrenal gland and the ovaries. Initially considered as an inert compound merely serving as an intermediate in the conversion of cholesterol to androgens, interest in DHEA began to grow in the 1960s when it was found that DHEAS is the most abundant steroid hormone in human plasma and that its levels decline with age. In many countries, DHEA is considered a nutritional supplement. It has been used for a multitude of conditions which include sexual dysfunction, infertility, genitourinary syndrome of menopause, musculoskeletal disorders, cardiovascular diseases, ageing, neurological diseases, autoimmune conditions, adrenal insufficiency, and anorexia nervosa. We describe an overview of the historical evolution of DHEA, its physiology, and the disease states where it has been evaluated as a supplement.

Hair-Based Assessment of Sex Steroid Hormones in Patients with Anorexia Nervosa

Anorexia nervosa (AN) is a complex psychiatric disorder accompanied by a variety of endocrine effects. Altered levels of the sex steroid hormones progesterone and dehydroepiandrosterone (DHEA) have been shown to occur in patients with AN using short-term hormonal measurement methods based on blood, saliva, and urine samples. However, since sex steroid hormone levels fluctuate during the menstrual cycle, these measurement methods require a great deal of effort due to the need to collect multiple samples in order to correctly determine the basal level of sex hormones. In contrast, hair-based assessments provide a marker of accumulated longer-term hormone exposure using a single, non-invasive sample. The aim of this study was to investigate sex steroid hormone levels via hair-based assessments in acutely underweight AN in comparison with healthy, age-matched, female control participants. Additionally, we compared progesterone and DHEA hair levels longitudinally during inpatient treatment in AN. Collected hair samples were analyzed using liquid chromatography-mass spectrometry (LC-MS/MS) to determine a monthly hormone level of progesterone and DHEA. Our results indicate that DHEA hair hormone levels were similar across groups but progesterone was suppressed in underweight AN compared with healthy controls. In the longitudinal design, no significant change in hair hormone levels during partial weight restoration in patients with AN was observed. Our findings suggest that hair analysis can be used to detect suppressed progesterone levels in severe AN, and that progesterone does not increase during short-term weight restoration.
