Background:
Polymyalgia rheumatica (PMR) is among the most common inflammatory rheumatic diseases in older adults. Presumed risk factors include female sex, previous infections, and genetic factors. No epidemiological data on PMR in Germany have been available until now.
Methods:
This review is based on publications retrieved by a selective literature search in PubMed. Moreover, the administrative incidence and prevalence of PMR in the years 2011-2019 was determined from data of the AOK Baden-Württemberg statutory health insurance carrier for insurees aged 40 and older. In addition, we quantified the number of consultations with physicians involved in the diagnosis.
Results:
The annual age- and sex-standardized incidence and prevalence of PMR from 2011 to 2019 were 18.6/100 000 persons and 138.8/100 000 persons, respectively. The incidence was higher in women than in men (21.8/100 000 vs. 12.8/100 000 persons per year). 60% of the cases were diagnosed in primary care practices. The treatment of PMR with orally administered glucocorticoids usually results in a treatment response within a few days to weeks. Approximately 43% of patients experience recurrent symptoms within a year, requiring adjustment of the glucocorticoid dose. For older patients with impaired physical ability, additional non-pharmacological treatment with exercise programs plays an important role.
Conclusion:
PMR usually takes an uncomplicated course under treatment and can be managed in primary care, but these patients are often multimorbid and require frequent follow-up. Along with research on the etiology of the disease, further studies are needed to identify the risk factors for a chronic course and to evaluate the potential effects of non-pharmacological measures.
Insights
Polymyalgia rheumatica (PMR) affects older adults, with higher incidence in women. While treatable with glucocorticoids, many patients experience symptom recurrence, highlighting the need for further research into risk factors and non-pharmacological treatments.
Area of Science:
- Rheumatology
- Epidemiology
- Geriatrics
Background:
- Polymyalgia rheumatica (PMR) is a common inflammatory rheumatic disease in older adults.
- Known risk factors include female sex, prior infections, and genetics.
- No prior epidemiological data for PMR in Germany was available.
Purpose of the Study:
- To determine the incidence and prevalence of PMR in Germany.
- To analyze diagnostic patterns and treatment responses.
- To identify needs for further research.
Main Methods:
- Literature search of PubMed publications.
- Analysis of administrative health insurance data (2011-2019) for individuals aged 40+.
- Quantification of physician consultations for PMR diagnosis.
Main Results:
- Annual age- and sex-standardized incidence: 18.6/100,000; prevalence: 138.8/100,000.
- Higher incidence in women (21.8/100,000) vs. men (12.8/100,000).
- 60% of diagnoses occurred in primary care; 43% of patients had recurrent symptoms within a year.
Conclusions:
- PMR is manageable in primary care, but patients are often multimorbid and require frequent follow-up.
- Glucocorticoid treatment is effective but requires dose adjustments due to recurrence.
- Further research is needed on etiology, chronic course risk factors, and non-pharmacological interventions.
