Technetium pertechnetate joint scintigrams were abnormal in 24 of 25 patients with polymyalgia rheumatica, in all 16 with rheumatoid arthritis, in 4 of 13 with nonarticular rheumatism, but in none of 26 control patients. Abnormal uptake in polymyalgia patients was commonest in shoulders and was less likely to be symmetric than in patients with rheumatoid arthritis, in whom distal joint abnormalities predominated. The pattern of abnormal uptake in polymyalgia rheumatica was not different in those with biopsy-proved giant cell arteritis. Correlation between symptoms and abnormal scintigrams was 72%, and abnormal uptake was present in 81% of joints of patients having physical abnormalities. Biopsy showed lymphocytic synovitis in the knee of one patient. After treatment the number of abnormal joints declined. These findings suggest that synovitis is common in polymyalgia rheumatica, and that it may account for some or most of the symptoms in this condition.

Of 159 patients with either polymyalgia rheumatica, seronegative rheumatoid arthritis (RA) or an undifferentiated syndrome with features of both who were followed for at least 30 months, synovitis recurred in 57. Twenty of the 57 patients had one episode of polymyalgia and another that looked like RA. Recurrences responded to prednisone and no joint destruction was seen. Temporal arteritis was seen with both diagnoses. These observations suggest that a benign symmetric synovitis occurs in older patients and may present as polymyalgia or as a polyarthritis that resembles RA.

Giant cell arteritis is a generalized vasculitis mainly affecting elderly people. The incidence is increasing, but only for women. The etiology is still unknown, but evidence suggests a cellular immunologic reaction against a local antigen present in the arterial wall. The disease can present itself with a great variety of symptoms. Constitutional symptoms such as fever, weight loss, and anorexia seem to be more common than hitherto believed. Onset of large artery involvement is independent of the evolution of the classic clinical symptoms. Peripheral synovitis is rarely seen in patients with polymyalgia rheumatica, and when it occurs, it is transient, nonerosive, and nondeforming. Glucocorticosteroids are the only generally accepted treatment in giant cell arteritis. After a higher initial dose of corticosteroids, most patients can be treated with a low maintenance dose, with little risk of steroid-induced osteoporosis. The erythrocyte sedimentation rate is still the best test for monitoring the disease.

Polymyalgia rheumatica and temporal arteritis appear to be separate syndromes rather than two manifestations of an underlying giant cell arteritis. Polymyalgia rheumatica is a synovitis that may be persistent or recurrent, while temporal arteritis is almost always a single episode; documented recurrences are rare. The two syndromes frequently occur in the same patient although not necessarily at the same time and they may be separated by a long interval. In some patients with polymyalgia rheumatica, giant cell arteritis is found on biopsy of an asymptomatic temporal artery. The frequency of this concurrence is variable in different populations. It is high in Scandinavia, low in Israel and intermediate between these extremes in other populations that have been studied.

Polymyalgia rheumatica is a syndrome that occurs in the elderly and is characterized by pain and stiffness involving the neck, the shoulder girdle, and the hip girdle. The aching should be present for greater than one month. Polymyalgia rheumatica may be more common than reported. The etiology remains unknown. There is generally little found pathologically in this disease. The physical examination is often not impressive. Synovitis may be a main contributing factor to many of the symptoms seen in patients with polymyalgia rheumatica. Symptoms often do not correlate with physical findings. Polymyalgia rheumatica must be differentiated from many conditions since the diagnosis remains entirely clinical. Osteoarthritis, flu syndromes, inflammatory myopathies, fibromyalgia, and depression all have features that may mimic polymyalgia rheumatica. Malignancies and infections may also be difficult to separate from polymyalgia rheumatica. Polymyalgia rheumatica may also be extremely difficult to differentiate from seronegative rheumatoid arthritis in patients older than 50 years. Although some patients with polymyalgia rheumatica have underlying giant cell arteritis, the majority apparently do not. The distinction between polymyalgia rheumatica and giant cell arteritis cannot be made on the basis of laboratory studies and relies solely on clinical symptoms and physical findings. Although nonsteroidal antiinflammatory medications may control symptoms in patients with mild disease, most patients with polymyalgia rheumatica require low-dose corticosteroids. The tapering schedule for the corticosteroids is contingent upon the response of symptoms and laboratory parameters. Polymyalgia rheumatica usually follows a benign course with almost complete response to an adequate treatment program. Recently, there have been several studies suggesting that the course of polymyalgia rheumatica may not be as short and simple as once proposed. Nevertheless, many patients may be completely weaned from corticosteroids. Other agents have been used in this disease, but for the most part their use remains somewhat controversial. Patients must be monitored carefully. Most patients do well, and treatment is effective.

The coincidence of arthritis with polymyalgia rheumatica (PMR) or temporal arteritis (TA) is not well established. After reviewing the literature we found that 22% of patients suffering from PMR/TA present with additional signs of inflammatory joint involvement. Joints predominantly affected are the sternal junctions, knee and shoulder joints, and the wrists, involvement of the latter frequently resulting in carpal tunnel syndrome. With the exception of sternal junctions, bony erosions are rarely seen. In most cases, synovitis is mild, pauciarticular, asymmetrical, transient and not destructive. Little evidence for inflammatory involvement of spine or sacroiliac joints was found, thus, back pain in these patients should be considered as caused by osteoporosis of the spinal column, mostly due to prolonged corticosteroid treatment.

Polymyalgia rheumatica and temporal arteritis are common syndromes of unknown cause that afflict older patients, the great majority of whom are white. Polymyalgia, which is seen more frequently, is a benign synovitis and can be differentiated from rheumatoid arthritis by the distribution of inflamed joints and by its rapid and complete response to small doses of prednisone. Temporal or giant cell arteritis occurs in approximately 20 per cent of patients with polymyalgia rheumatica and may present with either localized or systemic symptoms. Once the diagnosis is confirmed by temporal artery biopsy, patients should be treated with a large dose of prednisone for at least 1 month. The erythrocyte sedimentation rate is a useful test in suspecting the diagnosis initially, but is a poor gauge to tapering the steroid dose.

Among the population of Reggio Emilia, Italy, 56 patients with polymyalgia rheumatica (PR) and giant cell arteritis (GCA) were identified during the 5-year period 1981-85. The average annual incidence rates of PR and GCA were 12.8 and 8.8 respectively per 100,000 population aged 50 years or older. Forty-nine patients were followed up and the mean duration of follow-up was 32 months. All the patients received steroid therapy. We have evaluated the cumulative probability of requiring continued steroid therapy between patients with PR only, GCA only, and PR associated with GCA using life-table methods with permanent discontinuation of therapy as an end point. The different duration of steroid therapy between these 3 groups did not achieve statistical significance by the method of Lee and Desu. We identified a 5 variable discriminant function that correctly predicted whether the duration of therapy would be longer or shorter than 16 months (median duration of therapy) in 80% of our patients followed up for at least 24 months. The presence of synovitis in PR is also discussed.

One of the proposed mechanisms of vascular damage in connective tissue disease is the direct action of a cytotoxic serum factor inducing endothelial cell damage. The nature of this serum factor is unclear, but has been suggested to be a lipoprotein. Sera from patients with (1) systemic necrotising arteritis (polyarteritis nodosa, Wegener's granulomatosis, and necrotising arteritis associated with rheumatoid synovitis), (2) systemic or joint restricted rheumatoid disease, and (3) large vessel/giant cell arteritis have been examined for cytotoxicity to human cultured endothelial cells and azide-resistant ferroxidase-like activity (indicative of the oxidised lipoprotein content). Stored sera from patients with necrotising arteritis showed a significantly enhanced tendency to develop oxidised lipoprotein, which correlated closely with human endothelial cell cytotoxicity. Fresh sera also contained this factor, but to a lesser extent. It is argued that the cytotoxic factor detected in previous clinical studies is in part an in-vitro artefact, although its accelerated development in certain patient groups might suggest an excess of pro-oxidants that have developed in vivo.

Polymyalgia rheumatica is a relatively common syndrome of older patients, mostly white, manifested by aching and morning stiffness of the pelvic and shoulder girdles and accompanied by a rapid erythrocyte sedimentation rate. The symptoms are due to a synovitis, which is mild, nondestructive and very responsive to low-dose steroid treatment, which may need to be continued for several years. Temporal arteritis, which may accompany polymyalgia, can present as headache, loss of vision, diplopia or jaw claudication. To suppress arterial inflammation and preserve vision, administration of prednisone, 50 mg a day for one month, is recommended, following which the dose is tapered according to the symptoms, not the sedimentation rate.
