Assessment of Neuroendocrine Changes and the Hypothalamo-Pituitary Autoimmunity in Patients With COVID-19
Abstract Purpose: The SARS-CoV-2 may affect the hypothalamic-pituitary axis and pituitary dysfunction may occur. Therefore, we investigated neuroendocrine changes, particularly, secondary adrenal insufficiency using a dynamic test and the role of autoimmunity in pituitary dysfunction in the patients with COVID-19.Methods: The single-center, prospective, case-control study included PCR-confirmed COVID-19 patients and healthy controls. Basal hormone levels were measured and ACTH stimulation test was performed. Anti-pituitary (APA) and anti-hypothalamic antibodies (AHA) were also determined. Results: We examined a total of 49 patients with COVID-19 and 28 healthy controls. The frequency of adrenal insufficiency in patients with COVID-19 was found as 8.2%. The patients with COVID-19 had lower free T3, IGF-1, total testosterone levels, and higher cortisol and prolactin levels when compared with controls. We also, demonstrated the presence of APA in three and AHA in one of four patients with adrenal insufficiency. Conclusions: The COVID-19 may result in adrenal insufficiency, so the routine screening of adrenal functions is these patients is needed. Endocrine disturbances in COVID-19 are similar to those seen in acute stressful conditions or infections. Also, pituitary or hypothalamic autoimmunity may play a role in neuroendocrine abnormality in COVID-19..
