Polymyalgia Rheumatica (PMR) Referral Guideline

Warning

Patients with typical presentation, who have a complete, sustained response to low-dose corticosteroids, and who have no adverse events can be managed in primary care.

History

  • Age > 50 years
  • Duration > 2 weeks
  • Bilateral shoulder or pelvic girdle aching, or both
  • Morning stiffness duration of > 45 min
  • Evidence of an acute-phase response (e.g. raised ESR, CRP)

Examination

  • Shoulder, neck and hip range of movements - reduced
  • Muscle strength - normal
  • Patients should be assessed for evidence of GCA:
    • Temporal artery – tenderness, thickening, beading, reduced or absent pulsation
    • Scalp tenderness
    • Peripheral pulses upper extremities – diminished or lack
    • Auscultation of subclavian, axillary, brachial arteries – bruits
    • Blood pressure on both arms – discrepancy of more than 20mmHg in systolic pressure
    • If visual symptoms - vision acuity, eye movements, visual fields.

Helpful Investigations

  • FBC, U&E, LFT, bone profile, ESR, CRP, plasma viscosity
  • Immunoglobulins and electrophoresis (consider Bence Jones protein)
  • TFTs
  • CK
  • Rheumatoid factor (anti-nuclear antibody may also be considered)
  • CXR (if prominent systemic symptoms)
  • Dipstick urinalysis

Primary Care Management

  • Corticosteroids should be initiated and tapered as follows:
    • Daily prednisolone 15mg for 3 weeks
    • Then 12.5mg for 3 weeks
    • Then 10mg for 4-6 weeks
    • Followed by reduction by 1mg every 4–8 weeks
    • Usually 1-2 years of steroid treatment is needed.
  • Bone protection (weekly bisphosphonate and calcium or vitamin D supplementation).

Assess for corticosteroid-related adverse events: weight gain, diabetes, osteoporosis, hypertension and lipid dysregulation.

Who to Refer

  • Atypical features:
    • Younger patient < 60 years
    • Chronic onset (>2 weeks)
    • Lack of shoulder involvement
    • Lack of inflammatory stiffness
    • Red flag features: prominent systemic features, weight loss, night pain, neurological signs
    • Peripheral arthritis or other features of CTD or muscle disease
    • Normal or very high ESR/CRP.
  • Treatment dilemmas such as:
    • Incomplete or non-response to corticosteroids
    • Ill-sustained response to corticosteroids
    • Unable to reduce corticosteroids
    • Contraindications to corticosteroid therapy
    • The need for prolonged corticosteroid therapy (>2 years).

Who Not to Refer

  • Patients who have no atypical features, who have a complete sustained response to low-dose corticosteroids, and who have no adverse events.
  • Patients with alternative diagnosis more likely:
    • Active infection and cancer
    • Drug-induced myalgia, e.g. statins
    • Pain syndromes, e.g. fibromyalgia
    • Endocrine, e.g. thyroid
    • Neurological, e.g. Parkinson’s disease
    • OA, degenerative and other peri-articular conditions of the shoulder, neck and hips.
