Overview

Review demonstrates increased secondary osteoporosis and fracture risk from glucocorticoid therapy, highlighting the need for preventive bone-protective intervals.

Key Points

  • Synthesize current clinical evidence regarding the cellular and physiological mechanisms by which glucocorticoid therapy impairs bone remodeling and precipitates secondary osteoporosis.
  • Reviewed clinical and biological literature examining secondary osteoporosis caused by glucocorticoid (GC) exposure.
  • Assessed cellular pathways involving osteoblasts, osteoclasts, and osteocytes alongside clinical risk factors and fracture prevention strategies.
  • Glucocorticoid exposure is the most common cause of drug-induced osteoporosis, accounting for 20% of all osteoporosis cases.
  • GCs induce apoptosis in osteoblasts and osteocytes to suppress bone formation while simultaneously extending osteoclast lifespan to amplify net bone resorption.
  • Primary fracture risk factors include age over 65 years, low calcium intake, positive family history, and treatment lasting longer than 3 months, with fracture risk declining 3 months after cessation.
