How Are Polymyalgia Rheumatica and Giant Cell Arteritis Related?
It is unclear how or why polymyalgia rheumatica and giant cell arteritis are related, but an estimated 15 percent of people in the United States with polymyalgia rheumatica also develop giant cell arteritis. Patients can develop giant cell arteritis either at the same time as polymyalgia rheumatica or after the polymyalgia symptoms disappear. About half of the people affected by giant cell arteritis also have polymyalgia rheumatica. When a person is diagnosed with polymyalgia rheumatica, the doctor also should look for symptoms of giant cell arteritis because of the risk of blindness. With proper treatment, the disease is not threatening. Untreated, however, giant cell arteritis can lead to serious complications including permanent vision loss and stroke. Patients must learn to recognize the signs of giant cell arteritis, because they can develop even after the symptoms of polymyalgia rheumatica disappear. Patients should report any symptoms to the doctor immediately. A.
