Description of intervention(s) / exposure
Patients with a recent diagnosis of polymyalgia rheumatica (PMR) will be recruited, together with age- and gender-matched controls.

Data will be collected at two time points, 78 weeks apart.

The initial tests will be undertaken 12 weeks after the patient first commences prednisolone for their PMR.
Assessments will include:
- Questionnaires
- Blood tests
- Bilateral hand x-rays (in PMR participants only)
- Activity monitors
- Whole body composition DEXA (including vertebral fracture assessment)
- Peripheral quantitative CT scan
- Tests of muscle strength, power and function in a dedicated exercise laboratory

Further tests will occur 78 weeks later. Data collected will be the same as the initial tests, with the exception of bilateral hand x-rays (which will not be repeated), and not all blood tests will be repeated.

Not applicable
Comparator / control treatment
Control participants will be age- and gender-matched individuals without a diagnosis of PMR, who are not receiving regular prednisolone therapy for any other condition.

Statistical methods / analysis
At completion of the study period, statistical analyses will be undertaken using Stata 13.0 to compare the characteristics of participants with PMR to control participants. Parametric data will be compared using t-tests, while non-parametric data will be compared using the chi-square test or Kruskall-Wallis one-way analysis of variance. P-values of <0.05 will be classified as statistically significant. A more detailed multivariable and conditional logistic regression is also planned to control for the effects of variables such as gender, BMI and smoking status.

Summary
Brief summary
Polymyalgia rheumatica (PMR) is the most common inflammatory rheumatic condition in the elderly, and is typically treated with glucocorticoids (commonly known as 'cortisone' or 'steroids'). This study aims to examine the possible side effects of standard glucocorticoid therapy in people with a new diagnosis of PMR, with a particular focus on changes to muscle and bone health, including the incidence and prevalence of sarcopenia. People with a recent diagnosis of PMR, as well as people who have never been diagnosed with PMR, will undergo a series of assessments including questionnaires, physical examination, blood tests, imaging tests and physical tests in a dedicated exercise laboratory. Assessments will be repeated in all participants after 78 weeks, in order to examine the changes that occur. It is hypothesised that participants with PMR will demonstrate a greater decline in their muscle and bone health, and a higher incidence of sarcopenia, compared to participants without PMR. Ultimately, this would lead to a greater awareness of the need to address muscle and bone health during treatment of PMR.
