Glucocorticoid-Induced Osteoporosis

  |  

Osteoporosis is a condition of weak bone caused by a loss of bone mass and a change in bone structure. Glucocorticoid-induced osteoporosis is a form of osteoporosis caused by taking glucocorticoid medications, such as prednisone (Deltasone, Orasone, etc.), prednisolone (Prelone), dexamethasone (Decadron, Hexadrol), and cortisone (Cortone Acetate). These medications are used to help control many rheumatic diseases, including RA, systemic lupus erythematosus, and polymyalgia rheumatica.

Giant Cell Arteritis

  |  

Giant cell arteritis (GCA)—a type of vasculitis—is a group of diseases whose typical feature is inflammation of blood vessels. The blood vessels most commonly involved are the arteries of the scalp and head (especially the arteries over the temples), which is why another term for GCA is “temporal arteritis.” GCA can overlap with another rheumatic disease called polymyalgia rheumatica, and symptoms of the two conditions can occur at the same time or separately. The causes of GCA and polymyalgia rheumatica are unknown.
