Steroids for polymyalgia rheumatica
Steroids may be used as monotherapy in patients with PMR, Dr. Buttgereit observed, which is in contrast to other conditions such as RA. Although the evidence for use of steroids in PMR is limited, the EULAR Glucocorticoid Task Force and American College of Rheumatology recommended (Ann Rheum Dis. 2015;74[10]:1799-807) using a starting dose of a prednisolone-equivalent dose between 12.5 and 25 mg/day, and if there is an improvement in few weeks, the dose can start to be reduced. Tapering should be rapid at first to bring the dose down to 10 mg/day and followed by a more gradual dose-reduction phase.
“So, you can see we are giving more or less precise recommendations on how to start, how to taper,” Dr. Buttgereit said.
Balancing long-term benefit vs. harm
Balancing the long-term benefits and risks of steroids in rheumatic disease was the focus of a EULAR viewpoint article published 3 years ago in 2015 (Ann Rheum Dis. 2015;75[6]:952-7).
Three main messages can be drawn out of this work, Dr. Buttgereit said.
First, treatment with steroids for 3-6 months is associated with more benefits than risks if doses of 5 mg/day or less are used. There is one important exception to this, however, and that is the use of steroids in patients with comorbid cardiovascular disease.
Second, using doses of 10 mg/day for long periods tips the balance toward more risks than benefits, and “this means you should avoid this.”
Third, doses of 5-10 mg/day may be appropriate, but there are certain patient factors that will influence the benefit-to-harm ratio that need to be considered. These include older age, smoking, high alcohol consumption, and poor nutrition. There are also factors that may help protect the patients from risk, such as early diagnosis, low disease activity, low cumulative dose of steroids, and a shorter duration of treatment.
“It’s not only the dose, it’s also the absence or presence of risk factors and/or preventive measures,” that’s important, Dr. Buttgereit said.
