Overview

Polymyalgia rheumatica (PMR) must be differentiated from other conditions such as late onset rheumatoid arthritis, polymyositis, dermatomyositis, fibromyalgia, and remitting seronegative symmetrical synovitis with pitting edema.

Differentiating Polymyalgia Rheumatica from other Diseases

PMR must be differentiated from the following conditions:

Rheumatoid arthritis: PMR and late onset rheumatoid arthritis (RA) can initially present with similar clinical features like synovitis. These patients are treated initially as PMR with glucocorticoids. RA treatment is started when there is no improvement or when it evolves into characteristic RA or when there is a persistently raised plasma viscosity.^[1] ^[2]

Polymyositis and dermatomyositis: Patients with dermatomyositis or polymyositis present with tenderness and weakness of proximal muscles, while PMR patients present with pain and stiffness. This differentiation between these entities may be difficult in elderly patients. Proper history, complete physical examination, ESR, creatine kinase levels and muscle biopsy help in establishing the proper diagnosis.^[3] ^[4]

Malignancy (such as myeloma): Patients with malignancy sometimes present with PMR like symptoms and have poor response to steroid therapy.^[5] This is in fact paraneoplastic syndrome presenting as PMR.^[6]

Fibromyalgia: Fibromyalgia occurs in age groups 20-50 years. Patients have characteristic tender points. Unlike PMR, the active phase proteins and ESR are normal.

Hyperparathyroidism: Hyperparathyroidism presents with proximal stiffness and bone pain with elevated parathyroid hormone levels and often raised calcium levels without elevation of ESR levels.

Chronic infection (subacute bacterial endocarditis (SBE)): Rheumatologic symptoms seen in infective endocarditis can present as a clinical picture suggestive of polymyalgia rheumatica hindering the correct diagnosis.^[7]

Hypothyroidism: Patients with hypothyroidism muscle and joint pain and weakness similar to PMR. Delayed relaxation of deep tendon reflexes is seen in hypothyroidism with elevated TSH levels and low T4 levels.

Remitting seronegative symmetrical synovitis with pitting edema (RS3PE): RS3PE presents with symmetrical synovitis and pitting edema, usually in patients over 50 years of age and lack rheumatoid factor. Unlike PMR, the symptoms commonly manifest distally.

Differentiating polymyalgia rheumatica on the basis of fatigue and chronic pain

Disease	Differentiating signs and symptoms	Diagnostic findings
Polymyalgia rheumatica	Older at onset Generalized stiffness	An elevated erythrocyte sedimentation rate (ESR) OR C-reactive protein (CRP) Response to corticosteroids
Fibromyalgia	Symptoms have been present at a similar level for at least 3 months. Chronic musculoskeletal pain with multiple tender points Stiffness, numbness, and fatigue Headaches Sleep disorder	All lab tests are normal
Rheumatoid arthritis	Multiple joint swelling Morning stiffness Rheumatoid nodules	RF or anti-cyclic citrullinated protein (CCP) antibody is positive. Markers of systemic inflammation (ESR, CRP) are typically elevated.
SLE	Maculopapular rash Multi-system involvement	Positive anti-Smith antibodies
Chronic fatigue syndrome	Fatigue plus 4 of the following symptoms: Short-term memory loss Sore throat Tender lymph nodes in the neck or armpit Muscle pain Joint pain without swelling or redness Headaches Insomnia Malaise	Diagnosis of exclusions Symptoms must present for more than 6 months
Spondyloarthritis	Axial skeletal pain and stiffness Restricted spinal motion	Elevated ESR or CRP Negative RF Bamboo spine on x-ray
Osteoarthritis	Localized joint pain Restricted to affect joints Older at onset	X-ray of the involved joints demonstrate degenerative changes
Hypothyroidism	Systemic symptoms such as weight gain, constipation, dry skin Muscular aching and prominent fatigue that improves on replacement of thyroid hormone.	TSH is elevated and free T4 is low.
Myopathaies (polymyositis and dermatomyositis)	Pelvic and shoulder girdle muscle weakness Rash	Muscle biopsy confirms the diagnosis Elevated CPK enzyme
Neuropathy	Numbness and tingling Paresthesia	Abnormal EMG
