Teriparatide and denosumab treatment for pregnancy and lactation-associated osteoporosis with multiple vertebral fractures: A case study

Abstract

ObjectivePregnancy and lactation-associated osteoporosis (PLO) is a rare disease, which can lead to vertebral fractures in women of reproductive age. No treatment strategy for PLO has been established. Here we report a case of PLO treated with teriparatide followed by denosumab, in which remarkable improvement in bone mineral density (BMD) was achieved. Case reportA 27-year-old woman experienced severe back pain two weeks after her first delivery. PLO was diagnosed from her low BMD and multiple vertebral compression fractures. She was treated with teriparatide for 6 months, followed by denosumab. After 1 year, her BMD increase from baseline was 16.5% in L2∼4 and her pain had been relieved. ConclusionIn addition to weaning, administration of teriparatide followed by denosumab led to remarkable improvement in the patient's symptoms and BMD. Therefore, we regard this method as a promising choice for the treatment of PLO.
