BACKGROUND: The role of the renin-angiotensin-aldosterone system (RAAS) in coronavirus disease 2019 (COVID-19) is controversially discussed. Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) enters host cells by binding to angiotensin-converting enzyme 2 (ACE2) and activity of the RAAS may affect susceptibility to SARS-CoV-2 infection and outcome of patients with COVID-19. METHODS: In this prospective single-center study, we determined the serum levels of ACE2, angiotensin II, and aldosterone in patients with COVID-19 compared with control patients presenting with similar symptoms in the emergency unit. RESULTS: We analyzed serum samples from 24 SARS-CoV-2 positive and 61 SARS-CoV-2 negative patients. SARS-CoV-2 positive and control patients did not differ in baseline patients characteristics, symptoms, and clinical presentation. Mean serum concentrations of ACE2, angiotensin II, and aldosterone did not differ between the SARS-CoV-2 positive and the control group. In line with this, serum potassium as surrogate parameter for RAAS activity and blood pressure were similar in both groups. CONCLUSIONS: In summary, we did not find evidence for altered RAAS activity including angiotensin II, aldosterone, or potassium levels, and blood pressure in patients with COVID-19.
