Key result
Patients with depression had significantly higher nocturnal aldosterone concentrations compared to healthy controls during both the first (p=0.022) and second (p=0.009) halves of the night.
Why the study?
Does nocturnal RAAS activity differ between medication-free patients with depression and healthy controls?

Patients with depression exhibit nocturnal hyperaldosteronism compared to healthy controls, suggesting altered RAAS regulation and renal mineralocorticoid sensitivity.

May indicate aldosterone dysregulation in depression; hypothesis-generating and requires prospective validation before clinical consideration.
Murck et al. (2003) conducted a case-control in Depression (n=14). Depression vs. Healthy controls was evaluated on Nocturnal plasma concentration of aldosterone (AUC) in the first half of the night (23.00 h - 3.00 h) (p=0.022). Patients with depression had significantly higher nocturnal aldosterone concentrations compared to healthy controls during both the first (p=0.022) and second (p=0.009) halves of the night.
