ABSTRACT

Objective: To investigate the metabolic outcomes of primary aldosteronism (PA) patients receiving adrenalectomy (ADX) or spironolactone treatment and the contributing factors to the metabolic outcomes. Methods: The clinical data of 70 patients with aldosterone-producing adenoma (APA) and 86 patients with idiopathic hyperaldosteronism (IHA) were retrospectively analyzed. All subjects received confirmatory diagnosis of APA or IHA at the Department of Endocrinology and Metabolism, West China Hospital between March 2018 and October 2020. APA patients underwent ADX, while IHA patients were given spironolactone, a mineralocorticoid receptor antagonist (MRA). After ADX or spironolactone treatment, the outcomes of the metabolic indicators and the inter-group differences between the APA patients and IHA patients were studied. Results: There was no significant difference between the baseline data of the APA group and those of the IHA group in terms of age, sex, duration of hypertension, maximum systolic blood pressure (SBP-max), maximum diastolic blood pressure (DBP-max), body mass index (BMI), fasting blood glucose (FBG), lipid parameters, and renal function. IHA patients had higher waist circumference, serum potassium, and plasma renin activity (PRA) than those of the APA patients (all P<0.05). All patients showed significant improvement in blood pressure, blood potassium, and plasma aldosterone at follow-up. However, they also showed increased triglycerides (TG) accompanied by deterioration in renal function (P≤0.001). Multiple regression showed that TG levels were associated with spironolactone treatment for IHA patients and post-treatment BMI and creatinine levels. Furthermore, APA patients showed improvement in their FBG after ADX (P=0.041), while IHA patients showed elevated levels of FBG after spironolactone treatment (P=0.037). Conclusion: After treatment, PA patients still may experience abnormal lipid metabolism and deteriorating renal function. Spironolactone therapy may give rise to worse glucolipid metabolism than ADX therapy does.
