Investigation of Salivary Cortisol Response to Awakening in Underweight and Weight-Restored Patients with Anorexia Nervosa
Published online by Cambridge University Press: 23 March 2020
Abstract
Anorexia nervosa (AN) is characterized by dysregulated eating that leads to chronic malnutrition, which may be responsible for several physical complications, including endocrine alterations, such as hyperactivity of the hypothalamus-pituitary-adrenal (HPA) axis.
Several studies have shown a dysregulation of the cortisol awakening response (CAR) in symptomatic AN patients. However, it has not been established if the deranged CAR of underweight AN patients is a primary phenomenon or an alteration secondary to malnutrition.
The aim of this study was to explore the salivary CAR in both underweight and weight-restored patients with AN.
We recruited 59 women: 18 undernourished AN patients, 15 weight-restored AN women and 26 normal-weight healthy controls. Saliva samples were collected in the morning, immediately after awakening and after 15, 30 and 60 minutes, in order to measure saliva levels of cortisol. Participants filled in the state-trait anxiety inventory (STAI) to test their anxiety levels in the morning of the test.
Compared to healthy controls, underweight AN patients showed an enhanced CAR whereas the weight recovered patients had a normal CAR. These results were not correlated with levels of anxiety.
For the first time, our results demonstrate that the deranged CAR found in acute AN patients is not present in weight-restored ones, suggesting that altered activity of the HPA axis of symptomatic AN patients is a state-dependent phenomenon.
