A prospective study on endocrine function in patients with long-COVID symptoms.

Objective: To investigate hormonal status in patients with long-COVID and explore the interrelationship between hormone levels and long-COVID symptoms.

Design: Prospective observational study.

Participants: Patients who visited our long-COVID outpatients' clinic due to long-COVID symptoms from February 2021 to December 2022.

Persistent Endothelial Lung Damage and Impaired Diffusion Capacity in Long COVID.

Since the beginning of the pandemic, both COVID-19-associated coagulopathy biomarkers and a plethora of endothelial biomarkers have been proposed and tested as prognostic tools of severity and mortality prediction. As the pandemic is gradually being controlled, attention is now focusing on the long-term sequelae of COVID-19. In the present study, we investigated the role of endothelial activation/dysfunction in long COVID syndrome.

Endocrine Aspects of ICU-Hospitalized COVID-19 Patients.

The unprecedented scale of the current SARS-CoV-2/COVID-19 pandemic has led to an extensive-yet fragmented-assessment of its endocrine repercussions; in many reports, the endocrine aspects of COVID-19 are lumped together in intensive care unit (ICU) patients and non-ICU patients. In this brief review, we aimed to present endocrine alterations in ICU-hospitalized patients with COVID-19. There are tangible endocrine disturbances that may provide fertile ground for COVID-19, such as preexisting diabetes.

Testosterone, free, bioavailable and total, in patients with COVID-19.

Background: Low testosterone (mainly total testosterone [TTe]) has been noted in patients with COVID-19. Calculated free testosterone (FTe) and bioavailable testosterone (BavTe) may reflect more accurately this hormone's levels. In this study, we sought to assess TTe, FTe as well as BavTe in male patients with COVID-19.
