Polymyalgia Rheumatica

Introduction

Polymyalgia rheumatica and temporal arteritis occur in patients who are usually between 60 and 75 years of age. It is a painful muscle disease and shows laboratory evidence of inflammation and an immune system disorder. With polymyalgia rheumatica there is a swelling of the synovial lining of the joints leading to joint pain and swelling.

Temporal arteritis (also called “giant cell arteritis”) seems to be a variant of this disease where the elastic membrane of cranial arteries gets broken down. If the temporal arteries are affected, there is a danger of sudden onset blindness. About 1 in 1000 patients older than 50 years come down with temporal arteritis (Ref. 2).

Approximately 50% of these patients have polymyalgia rheumatica. About 33% of patients with polymyalgia rheumatica come down with temporal arteritis. In the past before corticosteroids were used in the treatment of giant cell arteritis about 30 to 60% of patients turned blind (Ref. 1).
