Polymyalgia rheumatica (PMR) and giant cell arteritis (GCA) in older adults are effectively treated with glucocorticoids, but monitoring for side effects is crucial. Steroid-sparing therapies are needed for better long-term control.
Area of Science:
- Rheumatology
- Geriatric Medicine
- Internal Medicine
Background:
- Polymyalgia rheumatica (PMR) and giant cell arteritis (GCA) are common inflammatory conditions in older adults.
- Diagnosis can be challenging due to overlapping symptoms and the need for definitive confirmation, especially for GCA.
- This study focuses on the geriatric population, addressing diagnostic and treatment complexities.
Purpose of the Study:
- To evaluate the clinical presentation of PMR and GCA in elderly patients.
- To compare diagnostic approaches, including clinical, laboratory, and histopathological methods.
- To assess treatment outcomes and adverse effects of therapies in geriatric patients.
Main Methods:
- A cross-sectional study involving 118 patients aged 50+ diagnosed with PMR and/or GCA.
- Data collected via interviews, medical records, and diagnostic reports.
- Statistical analysis of clinical characteristics, lab markers, and treatment responses.
Main Results:
- PMR diagnosis relied on clinical symptoms and elevated inflammatory markers (CRP/ESR).
- Giant cell arteritis (GCA) was confirmed by temporal artery biopsy (TAB) in 76% of suspected cases; vascular ultrasound showed the "halo sign" in 67%.
- Glucocorticoids achieved remission in 84% but caused hyperglycemia (28%) and osteoporosis (14%); delayed treatment increased relapse rates (p=0.04).
Conclusions:
- Glucocorticoid therapy is effective but requires monitoring for adverse effects like hyperglycemia and osteoporosis.
- Tocilizumab use was associated with higher relapse and metabolic complications.
- Personalized treatment strategies and steroid-sparing options are essential for long-term management of PMR and GCA in the elderly.

Bone Disorders
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...
