Summary

Idiopathic inflammatory myopathies (IIM) patients are at high risk of development of reduced bone mineral density due to impairment of functional status due to the disease and a relatively high dose of glucocorticoid use for the treatment. Reduced bone mineral density is prevalent in local IIMs patients. Denosumab and zoledronic acid are established treatments for osteoporosis in postmenopausal women and glucocorticoid-induced osteoporosis. However, the role of these treatments in reduced bone mineral density including osteoporosis and osteopenia related to IIMs are lacking. There is also no evidence on comparing the efficacy of the two agents. Therefore, the investigators conducted this prospective randomized controlled study to compare the efficacies of denosumab and zoledronic acid in treating reduced bone mineral density in IIMs patients. The hypothesis in this study is that treatment by denosumab or zoledronic acid would improve bone mineral density in IIMs patients with reduced bone mineral density.

Conditions

  • Idiopathic Inflammatory Myopathies
  • Osteoporosis, Osteopenia

Interventions

DRUG

Denosumab

Denosumab is a human monoclonal antibody against receptor activator of nuclear factor kappa-B ligand (RANKL) and its use is associated with a reduced risk of vertebral, non-vertebral and hip fracture in post-menopausal women. RANKL plays a crucial role in the pathogenesis of glucocorticoid-induced osteoporosis (GIOP). Its production is increased by GC, resulting in stimulated osteoprotegerin ligand production and increased bone resorption. Recent randomized controlled trial from Saag et al have shown that denosumab is more efficacious than risedronate in the improvement of BMD in GIOP patients. Denosumab has been confirmed efficacious in GIOP patients but its efficacy in high-risk osteopenia patients are not well studied. It is given subcutaneously at 60mg every 6 months.

DRUG

Zoledronic Acid

Zoledronic acid belongs to bisphosphonates and is licensed for the treatment of GIOP and 2 RCTs found zoledronic acid has superior efficacy in improvement in BMD at lumbar spine or femoral neck at 12 months when compared to risedronate. It is given intravenously every year at a dosage of 5mg.
