Abstract
CONTEXT: Activation of the renin-angiotensin-aldosterone system (RAAS) is associated with high serum PTH concentrations and vice versa. OBJECTIVE: The aim of this study was to analyze the associations of the plasma aldosterone concentration (PAC), the plasma renin concentration (PRC), or the aldosterone to renin ratio (ARR) with serum PTH concentrations in a sample from the general population of northeast Germany. DESIGN: We selected 3105 subjects (25-88 y) from the first 5-year follow-up examination of the Study of Health in Pomerania. The associations of PAC, PRC, or ARR with serum PTH concentrations were examined with multivariable linear regression analyses. We further calculated adjusted mean serum PTH concentrations according to PAC, PRC, and ARR categories (≥90th and < 90th sex specific percentiles and sex specific quartiles). The models were adjusted for age, sex, estimated glomerular filtration rate, serum 25-hydroxy vitamin D concentration, waist circumference, body mass index, hypertension, diabetes mellitus, liver disease, and intake of drugs that affect the RAAS or bone metabolism. RESULTS: We found no associations between PAC or PRC and serum PTH concentrations in fully adjusted linear regression models. However, fully adjusted linear regression and ANOVA models revealed higher serum PTH concentrations in subjects with an ARR 90th percentile or greater than in subjects with a lower ARR. CONCLUSIONS: Our data show that a high ARR is associated with high serum PTH concentrations in the general population and thus add to the increasing evidence of a relation between the RAAS and PTH.
