Epidemiology and optimal management of polymyalgia rheumatica
1Department of Rheumatology, Centre Hospitalier Spécialisé, Institut Calot, Berck sur Mer, France.
Abstract:
Polymyalgia rheumatica (PMR) is a disease of unknown aetiology that occurs in elderly patients, predominantly affecting the Caucasian population. The disease has a slightly higher prevalence in women than in men. There is ongoing discussion regarding the relationship between PMR and giant cell arteritis; an increasing number of studies indicate that they are closely related. PMR has also been linked with rheumatoid arthritis, myopathy and malignant disease. Oral corticosteroids remain the mainstay of drug therapy for PMR. These drugs usually induce prompt relief of symptoms, and some authors consider this dramatic response to be diagnostic for PMR. However, the ideal initial dosage, the duration of treatment and the optimal tapering schedule are much debated. Other drugs, such as methotrexate and azathioprine, have been suggested as corticosteroid sparing agents. Nonsteroidal anti-inflammatory drugs are generally considered to be unsuitable for the long term treatment of PMR.
Insights
Polymyalgia rheumatica (PMR) is an inflammatory condition primarily affecting older adults. Oral corticosteroids are the primary treatment, offering rapid symptom relief, though optimal dosing and duration remain debated.
Area of Science:
- Rheumatology
- Internal Medicine
- Geriatrics
Background:
- Polymyalgia rheumatica (PMR) is a disease of unknown cause affecting elderly Caucasians, with higher prevalence in women.
- PMR is increasingly recognized as closely related to giant cell arteritis and has associations with rheumatoid arthritis, myopathy, and malignancy.
Purpose of the Study:
- To summarize current understanding of polymyalgia rheumatica (PMR) etiology, associations, and management.
- To highlight the diagnostic role of corticosteroid response and discuss treatment controversies.
Main Methods:
- Literature review and synthesis of existing studies on PMR.
- Analysis of the relationship between PMR, giant cell arteritis, and other conditions.
- Evaluation of current therapeutic strategies for PMR.
Main Results:
- Oral corticosteroids are the primary therapy, providing prompt symptom relief, often considered diagnostic.
- Debate exists regarding optimal corticosteroid dosage, treatment duration, and tapering schedules.
- Corticosteroid-sparing agents like methotrexate and azathioprine are considered, while NSAIDs are generally unsuitable for long-term PMR treatment.
Conclusions:
- PMR management primarily relies on oral corticosteroids, with ongoing research into optimal treatment protocols.
- Understanding PMR's associations is crucial for comprehensive patient care.
- Further research is needed to explore alternative and steroid-sparing therapies.
