Background
- Chronic inflammatory condition
- Primarily affects elderly
Clinical Features
- Onset abrupt or subacute (weeks-months)
- Proximal myalgia primarily involving hips, shoulders, and neck
- Morning stiffness
- Giant cell arteritis develops in approximately 15% of patients with PMR[1]
- +/- constitutional symptoms (fatigue/malaise, low-grade fever, anorexia)
- +/- anemia
- Rheumatoid arthritis-like symptoms (joint pain/swelling, degenerative changes) in 30% of patients[2]
Differential Diagnosis
Myalgia
- Infection:
- Viral infection (e.g. Influenza)
- Bacterial infection
- Spirochete infection (E.g. Dengue fever; Trichinella)
- Drugs:
- Statins
- Bisphosphonates
- Corticosteroids
- Ciprofloxacin
- Clofibrate
- Colchicine
- Chloroquine
- Emetine
- Aminocaproic acid
- Zidovudine
- Bretylium
- Penicillamine
- Drugs causing hypokalemia
- Metabolic disorders:
- Vitamin D deficiency
- Mitochondrial myopathy
- Scurvy
- Osteomalacia
- Fibromyalgia
- Endocrine:
- Polymyalgia rheumatica
- Rhabdomyolysis
- Myositis
- Systemic lupus erythematosus
- Rheumatoid arthritis
- Inclusion body myositis
- Sarcoidosis
- Scleroderma
- Sjögren’s syndrome
- Psychiatric (e.g. somatic manifestations of depression)
- Domestic abuse
- Crush injury
- Lyme disease
- Ehlers-Danlos syndrome(hypermobility syndrome)
- HIV myopathy
- Hypophosphatemia
- Hypokalemia
- Hypothermia
- Prolonged immobility
- Strenuous exercise (overuse) or heat stroke
- Seizure
- Severe volume contraction
- Alcoholism
- Muscular dystrophy
- Duchenne
- Becker
- Limb-girdle
- Facioscapulohumeral
- Myotonic dystrophy
- Myotonia congenita
- Compartment syndrome; Muscle infarction
- Neuropathic
- Chronic fatigue syndrome
- Vasculitis
- Sarcocystosis
- Spinal stenosis
- Diabetic lumbosacral plexopathy
Evaluation
- Clinical diagnosis
- Evaluate for alternate diagnoses
Management
- Low-dose Corticosteroids typically produce rapid response[3]
- Avoid NSAIDs if history of or concern for GCA due to risk of renal injury
Disposition
- Discharge
