title: Normocalcemic primary hyperparathyroidism in a patient with severe osteoporosis receiving teriparatide.
abstract: We describe here the case of an elderly female with severe osteoporosis, who presented with a worsening backache, following teriparatide treatment. She was subsequently diagnosed to have normocalcemic primary hyperparathyroidism. Before prescribing teriparatide, an appropriate endocrine evaluation must be undertaken by all healthcare physicians (serum intact parathyroid hormone (iPTH) level), despite having a normal serum calcium. Normocalcemic hyperparathyroidism should be considered as an important alternate cause for osteoporosis.
