Fecal elastase 1 and vitamin D3 in patients with osteoporotic bone fractures.

Abstract

Exocrine pancreatic insufficiency, especially lowered fecal elastase 1, may be much more frequent in patients with osteoporotic bone fractures than suggested so far. Lowered exocrine pancreatic function with lowered fecal elastase 1 seems to be relevant as a reason for reduced levels of circulating vitamin D3 metabolites being an appropriate additional cause for predominant osteoporosis.
