Summary
Patients with polymyalgia rheumatica (PMR) and/or temporal arteritis (TA) experiencing elevated white blood cell counts or high erythrocyte sedimentation rates (ESR) may require prolonged steroid therapy. Rapid steroid dose reduction increases relapse risk.
Area of Science:
- Rheumatology
- Internal Medicine
Context:
- Polymyalgia rheumatica (PMR) and temporal arteritis (TA) are inflammatory conditions often treated with corticosteroids.
- Long-term management of PMR/TA can be complicated by steroid resistance and relapses.
Purpose:
- To identify factors associated with prolonged corticosteroid use and relapses in patients with PMR and/or TA.
- To analyze the clinical course and treatment duration in a cohort of 28 patients.
Summary:
- Higher baseline erythrocyte sedimentation rate (ESR) and elevated white blood cell counts were significant predictors of corticosteroid resistance (P < 0.01).
- A faster reduction in corticosteroid dosage was significantly associated with an increased risk of relapse (P < 0.05).
- Immunosuppressive therapy is recommended for patients with corticosteroid-resistant disease, relapses, or PMR associated with TA.
Impact:
- Findings suggest that specific clinical parameters can predict treatment resistance and relapse in PMR/TA patients.
- Highlights the need for individualized treatment strategies, potentially incorporating immunosuppressants earlier for at-risk patients.
- Informs clinical decision-making regarding corticosteroid tapering and the use of combination therapy in managing PMR and TA.
