ObjectiveTo analyse the differences in the cardio-metabolic profile of patients with primary aldosteronism (PA) and autonomous cortisol secretion (ACS) matched by age and sex.MethodsCase-control study; cases of PA without associated ACS and as controls patients with ACS (dexamethasone suppression test ≥ 1.8 μg/dL in the absence of specific hypercortisolism clinical data), matched by age and sex. Comorbidities of hypertension, diabetes, obesity, dyslipidaemia, chronic kidney failure, and cardiovascular and cerebrovascular events were analysed, as well as their degree of control.Results57 patients with PA and 57 with ACS were included. On diagnosis, in addition to a higher prevalence of hypertension in the PA patients (100 vs. 52.7%, p < .0001) and higher systolic blood pressure levels (143.2 (2.5) vs. 135.3 (2.6) mmHg, p = .032) than in the ACS patients, no other differences were detected in the prevalence of other cardio-metabolic comorbidities. Nevertheless, the patients with ACS had higher HbA1c levels (p = .028) than the PA patients. After a median follow-up of 2.25 years, the patients with PA presented a greater deterioration in kidney function (Average decrease in glomerular filtration rate (MDRD-4) -17.4 (3.0) vs. -2.3 (4.4) mL/min/1.73 m2, p = .005) and lipid profile (Δtriglycerides of 34.5 (15.8) vs. -6.7 (11.3) mg/dL, p = .038) than the ACS patients.ConclusionsDespite the higher prevalence of hypertension in the patients with PA than in the patients with ACS matched by age and sex, no differences were detected in the prevalence of other cardio-metabolic comorbidities. However, the PA patients showed a greater deterioration in kidney function and lipid profile throughout the follow-up than the ACS patients.Copyright © 2020 Elsevier España, S.L.U.
