- Abstract
The causes of adrenal Cushing's syndrome (CS) encompass a wide spectrum of adrenal cortisol proliferations that exhibit clinical and molecular heterogeneity. The aims of our study were to investigate whether clinical and molecular heterogeneity influences endothelial function and metabolic abnormalities in patients with cortisol-producing adenoma (CPA). We retrospectively enrolled 25 patients with CPA and 45 patients with essential hypertension (EH). All CPAs were studied by direct sequencing of PRKACA. Flow-mediated vasodilation (FMD), an index of vascular endothelial function, was significantly lower in CS and subclinical CS (SCS) groups than in the EH group. FMD impairment did not differ significantly between CS and SCS groups. No differences in FMD were seen between PRKACA mutant and wild-type groups. FMD correlated negatively with hemoglobin A1c (HbA1c) in both PRKACA mutant and wild-type groups, as well as in CS and SCS groups. After adrenalectomy, systolic blood pressure (SBP) and HbA1c decreased significantly from baseline in the CS group, and SBP and low-density lipoprotein cholesterol (LDL-C) decreased significantly from baseline in the SCS group. While SBP and LDL-C decreased significantly from baseline in patients with wild-type PRKACA, only HbA1c decreased from baseline in patients harboring PRKACA mutations. Our data showed that patients with CPA have impaired endothelial function compared with EH patients and suggest the need for strict monitoring of atherosclerosis, even in patients with SCS or without PRKACA mutation.
