Intro
What is Polymyalgia Rheumatica (PMR)?
PMR is a common condition in older people characterized by muscle stiffness and elevated inflammatory markers, closely related to temporal arteritis.
What age group is typically affected by PMR?
Patients are typically over 60 years old.
What are the key features of PMR?
Rapid onset (e.g., < 1 month), aching, morning stiffness in proximal limb muscles, mild polyarthralgia, lethargy, depression, low-grade fever, anorexia, night sweats.
What investigations are relevant for PMR diagnosis?
Elevated inflammatory markers (e.g., ESR > 40 mm/hr), normal creatine kinase, and EMG.
How is PMR treated?
Prednisolone (e.g., 15mg/od) is the primary treatment. Patients typically respond dramatically, and failure to do so should prompt consideration of an alternative diagnosis.
