Context: Coronavirus disease 2019 (COVID-19) predominantly involves the lungs, albeit many other organ systems, including the hypothalamic-pituitary-adrenal (HPA) axis, can be affected due to the expression of the angiotensin-converting enzyme 2 (ACE2) binding receptor. Few studies have reported the involvement of adrenal gland and the HPA axis during the acute phase of COVID-19; however, the data on the long-term effect of COVID-19 on the HPA axis after acute infection is scarce.

Objective: To assess and compare the changes in HPA axis in mild, moderate and severe COVID-19 categories at ≥ 3 months after acute infection.
