This study aimed to explore the risk factors for lower bone mineral density (BMD) in primary aldosteronism (PA) patients. The results showed that PA patients had lower BMD compared to essential hypertension (EH) patients, and this was associated with age, serum phosphorus, urinary calcium excretion, mean platelet volume (MPV), superoxide dismutase (SOD), and total bilirubin (TBIL).
PurposeThe association between primary aldosteronism (PA) and lower bone mineral density (BMD) has raised a concern, but the contributing factors remain unclear. We aim to explore the risk factors for lower BMD in PA patients. MethodsWe analyzed and compared the data of 60 PA patients with 60 matched essential hypertension (EH) patients. BMD, bone metabolites, and several oxidative stress and inflammation indicators-including C-reactive protein (CRP), superoxide dismutase (SOD), total bilirubin (TBIL), mean platelet volume (MPV), etc.-were assessed and compared in PA and EH patients. Bivariate correlation analysis and multivariate linear regression analysis were performed to explore the factors associated with BMD in PA patients. ResultsThe BMD measured by quantitative computed tomography in PA patients was lower than that in EH patients (141.9 +/- 34.0 vs. 158.9 +/- 55.9 g/cm(3), p = 0.047), especially in patients less than 50 years old. BMD was independently negatively associated with age (standardized beta = -0.581, p < 0.001), serum phosphorus (standardized beta = -0.203, p = 0.008), urinary calcium excretion (standardized beta = -0.185, p = 0.031), and MPV (standardized beta = -0.172, p = 0.043) and positively associated with SOD (standardized beta = 0.205, p = 0.011) and TBIL (standardized beta = 0.212, p = 0.015). ConclusionsThe PA patients showed a lower BMD than the EH patients, which was associated with age, serum phosphorus, urinary calcium excretion, MPV, SOD, and TBIL. These variables might be potential markers for the assessment of bone loss and efficacy of treatments in PA patients.
