Osteoporosis is a serious condition with dire consequences, especially in individuals using glucocorticoids longterm. Management strategies for prevention and treatment are tailored to different age groups, emphasizing the importance of peak bone mass attainment and fracture risk assessment in adults. Additional expertise is recommended for complicated cases.
Osteoporosis is a silent disorder with dire consequences, and glucocorticoid use remains the most common iatrogenic cause illustrated by the fact that 30% to 50% of subjects on such longterm therapy experience fractures (Oimomi M, Nakamichi T, Ohara T, Sakai M, Igaki N, Hata F, et al. Fructose-related glycation. Diabetes Res Clin Pract 1989;7:137-9; Reid IR. Glucocorticoid osteoporosis-mechanisms and management. Eur J Endocrinol 1997;137:209-17). By directly affecting bone quality while actively used, glucocorticoids increase the risk of fracture that is independent of a subject's bone density status at the time (Weinstein RS. True strength. J Bone Miner Res 2000;15:621-5). A large number of subjects seen in an allergy and immunology clinic have asthma, chronic rhinosinusitis, or other chronic inflammatory diseases, necessitating the use of these medications and placing them at higher risk for this disease. Data on the effects of both oral and inhaled glucocorticoids on fracture risk are presented. This review concretizes the importance of osteoporosis, its pathophysiology, and provides practical guidelines to prevent and treat it. Management recommendations are tailored to 2 different age groups. The first group consists of children, adolescents, and adults 40 years or younger with a focus on attaining peak bone mass. The second group consists of adults 40 years or older where the use of imaging modalities and Fracture Risk Assessment Tool scores helps triage subjects into fracture risk categories. Those at moderate to high risk require bone-sparing medications. Universal preventive measures for both groups are reviewed. Complicated and severe cases may need additional expertise by an endocrinologist or rheumatologist. (c) 2021 American Academy of Allergy, Asthma & Immunology
