Giant cell arteritis can be difficult to diagnose because its early symptoms resemble those of other common conditions. The diagnosis of giant cell arteritis is suspected when a patient over the age of 50 (usually over 60) develops symptoms above and/or suddenly develops blindness or stroke.The diagnosis is supported by signs of inflammation in the blood indicated by an elevation in the erythrocyte sedimentation rate and/or C-reactive protein.. The diagnosis of GCA should be considered in any patient over the age of 50 with new headaches, acute visual changes, symptoms of polymyalgia rheumatica, unexplained constitutional symptoms, or jaw claudication. The diagnostic criteria for GCA is based on analysis of 214 cases of GCA compared with a sample of 593 patients with other vasculitis types. Forty two TABs were performed during this period of which 10 were males and 32 females. Giant cell arteritis is a disease characterized by inflammation of the arteries, a type of blood vessel.

GCA is also a classic systemic rheumatic disease of older adults; it virtually never occurs in individuals younger than 50 years of age and peaks in incidence in the seventh decade [ 2 ]. Giant cell arteritis is a vasculitis of large and middle-sized arteries that affects patients aged over 50 years. GCA typically occurs in people 50 years of age or older and is more common in women. However, meeting classification criteria is not equivalent to making the diagnosis in individual patients, and the final diagnosis should be based on all clinical, laboratory, imaging and … Giant cell arteritis (GCA) or temporal arteritis (TA) with polymyalgia rheumatica (PMR) is among the most common reasons for long-term steroid prescription. View/Print Table TABLE 1 Complication can include blockage of the artery to the eye with resulting blindness, aortic dissection, and aortic aneurysm. Giant cell arteritis (GCA, also known as Horton disease, cranial arteritis, and temporal arteritis) is the most common of the systemic vasculitides . Giant cell arteritis (GCA) or temporal arteritis (TA) with polymyalgia rheumatica (PMR) is among the most common reasons for long-term steroid prescription. The doctor will perform a physical examination and will check to see whether the patient's pulse is weak. Thus, clinical suspicion of giant cell arteritis must remain high on the differential diagnosis, as a delay in diagnosis and treatment initiation can lead to progressive vision loss and even binocular blindness, as well as devastating large-vessel involvement. Giant cell arteritis is an inflammation of the lining of your arteries. It is a critical ischaemic disease and should be treated as a medical emergency. A retrospective study was conducted of patients undergoing TAB from August 2014 to August 2016, at a DGH. Criteria for the classification of giant cell (tem- poral) arteritis were developed by comparing 214 pa- tients who had this disease with 593 patients with other forms of vasculitis. Data collected included patient demographics, history, biochemistry, time to TAB from commencement of steroids and histology. A fast diagnosis is important to prevent serious complications. Giant cell arteritis (GCA) is a granulomatous vasculitis commonly of the temporal artery associated with polymyalgia rheumatic that classically presents in those above the age of 50 with a new temporal headache; it may be associated with rapid irreversible bilateral visual loss and thoracic aortic aneurysm (late). The AUC for rACR was 0.880 (p < 0.001) and for ACR was 0.737 (p = 0.023). The American College of Rheumatology criteria for the classification of giant cell arteritis may assist in the diagnosis.
