| Summary: | Glucocorticoid-induced osteoporosis (GIO) is the most common cause of secondary osteoporosis (OP) and a main cause of drug-induced OP. Fractures of the skeleton are registered in 30–50% of patients who have taken oral glucocorticoids (GCs) for a long time, during which the frac- tures develop with the use of any daily GC dose and with higher bone mineral density (BMD) than in postmenopausal OP. In patients who have taken oral GCs long or in high daily doses, decrease of BMD and low bone tissue quality leading to fractures are largely associated with the reduction of bone formation. This gives proof to the administration of antiosteoporotic agents that enhance the formation of bone during its remodeling. Teriparatide, a recombinant human parathyroid hormone, enhances osteoblast function, decreases the apoptosis of osteoblasts and osteocytes, increases the differentiation of osteoblast precursors, and can prevent the negative effect of exogenous GCs on bone. According to clinical trials results, teriparatide treatment increases BMD and reduces the risk of vertebral fractures in patients who have taken oral GCs long. In accordance of the clinical recommendations for the diagnosis, prevention, and treatment of GIO, which have been developed by the Russian Osteoporosis Association jointly with the Association of Rheumatologists of Russia and the Russian Respiratory Society, teriparatide is the drug of first choice for the treatment of GIO in men and women at high risk for fractures (with the history of fragility fractures or having high FRAX 10-year absolute fracture risk). Teriparatide may be prescribed in case of previous antiosteoporotic treatment failure (new fractures occurring during treatment and/or continuing to decrease BMD), as well as when other drugs to treat OP are intolerable or when there are contraindications to their use. |
