Multiple corticosteroid abnormalities in cats with hyperaldosteronism

Background The frequency with which multiple corticosteroid abnormalities occur in cats with aldosterone secreting adrenocortical tumors is unknown. Objectives To evaluate adrenal‐derived corticosteroids in cats in which blood samples were submitted for measure of aldosterone. Animals Two hundred ninety‐seven cats. Methods Retrospective study. Analysis of a convenience sample of previously submitted serum or plasma. Progesterone, corticosterone, and cortisol were measured in feline serum or plasma samples submitted to an endocrinology laboratory for aldosterone measurements. Demographics and clinical history were retrieved from submittal forms when provided. Statistical testing was performed to investigate associations among the adrenal corticosteroids. Results Progesterone and corticosterone concentrations were strongly correlated (ρ = 0.74; P
