Anticardiolipin antibody levels predict flares and relapses in patients with giant-cell (temporal) arteritis. A longitudinal study of 58 biopsy-proven cases

Abstract

Serum aCL levels are useful in the detection of flares and relapses in giant-cell arteritis, with fairly good sensitivity (74%) and a specificity of 100%, and can be of value in distinguishing subclinical flares from infection.
