Abstract

Introduction: Concentrations of 1,25-hydroxyvitamin D have been positively associated with dietary sodium and salt sensitivity (SS) of blood pressure (BP), and inversely with plasma renin activity (PRA). We investigated the association between PRA and 25-hydroxyvitamin D (25OHD), the most clinically relevant vitamin D metabolite, and whether 25OHD associates with SS of BP in renin phenotypes of hypertension. Methods: We performed cross-sectional analyses on 223 Caucasian subjects with hypertension maintained in high and low dietary sodium balance. Subjects were distinguished as having low-renin (LR) or normal-renin (NR) hypertension. Multivariable linear regression was used to evaluate adjusted relationships. Results: Increasing 25OHD concentrations were inversely associated with PRA ( p < 0.05) on both salt diets. Furthermore, 25OHD was associated with SS of BP in LR hypertension (b = 0.62, p = 0.04), but not in NR hypertension (b = 0.06, p = 0.59). In an adjusted multivariable interaction model, renin status (LR vs . NR) was a significant effect modifier of the relationship between 25OHD and SS of BP ( p = 0.04). Conclusions: Our findings suggest that 25OHD is inversely associated with PRA and positively associated with SS of BP in LR hypertension subjects. These results extend and support prior evidence indicating an interaction between dietary sodium, the RAS, and vitamin D that influences BP in hypertension.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
