Peak age for GCA

Patients 70 to 80 years old are most commonly affected by giant cell arteritis (GCA).

GCA etiology (main idea)

The exact cause of giant cell arteritis (GCA) is unknown, but it's believed that a body's inappropriate immune response to injury in blood vessel walls contribute.

GCA's effect on blood vessels

GCA primarily affects the lining of medium and large blood vessels, causing inflammation.

GCA risk factor

Age over 70 is the most significant risk factor for giant cell arteritis (GCA).

GCA common association

A large percentage (40-60%) of GCA patients also experience Polymyalgia Rheumatica (PMR) symptoms.

Giant Cell Arteritis (GCA) Symptoms

GCA patients experience constitutional symptoms like fever, fatigue, and weight loss, along with visual disturbances (e.g., amaurosis fugax, diplopia), and potential vision loss. Jaw claudication, scalp tenderness, extremity claudication, and PMR symptoms are also common.

GCA Physical Exam Findings

Physical exam reveals temporal artery abnormalities (tenderness, beading), peripheral pulses decreased or absent, and funduscopic findings like optic disc edema. Unlike some other vasculitis, skin, kidney & lung involvement is rare.

GCA Diagnostic Criteria (ACR)

The American College of Rheumatology (ACR) criteria for GCA include age over 50, new headache, temporal artery abnormality, elevated ESR (>50 mm/hr), and abnormal temporal artery biopsy showing vasculitis with specific cell infiltration.

GCA Diagnostic Tests

Initial tests for GCA involve measuring the erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP). A high ESR (>50 mm/hr) or high CRP (>2.45 mg/dL) often suggests GCA, although normal results don't rule it out.

GCA Differential Diagnosis

GCA is differentiated from other conditions: Migraine, herpes zoster, other vasculitis (Takayasu, Wegener, PAN), and rheumatologic conditions (RA, PMR, MCTD).
