Seasonal variation in serum concentrations of parathyroid hormone in elderly people.

P Lips, W H Hackeng, M J Jongen, F C van Ginkel, J C Netelenbos.   

Abstract

In 124 patients with femoral neck fracture and 74 aged control subjects a seasonal variation was observed in the serum concentrations of 25-hydroxyvitamin D, 24,25-dihydroxyvitamin D, and PTH. The serum PTH concentrations were maximal in winter, when the vitamin D metabolites were lowest, suggesting a secondary phenomenon.
