title: Vitamin D in Paget's disease of bone.
abstract: The role of vitamin D metabolism in Paget's disease of bone has not been well defined. Serum levels of the main, circulating vitamin D metabolites were measured in 23 patients with Paget's disease. Values of 25(OH)D3 and 24,25(OH)2D3 were within the normal range in most (more than 90%) of the subjects. 1,25(OH)2D3 was increased in 11 (48%) patients. Markedly elevated levels (93-298 pg/ml) were found in five patients. In a subgroup of patients with high 1,25(OH)2D3, the mean serum alkaline phosphatase activity was insignificantly higher, while serum calcium, phosphorous, and kidney function were the same as in a subgroup with normal 1,25(OH)2D3. 1,25(OH)2D3 levels were not affected by treatment with either calcitonin or etidronate disodium. Serum 1,25(OH)2D3 levels may be increased in a subset of patients with Paget's disease of bone.
