Diagnostik und Therapie von Großgefäßvaskulitiden

Giant cell arteritis (GCA) and Takayasu arteritis (TAK), as the main representatives of large vessel vasculitis, are rheumatological autoimmune disorders associated with inflammatory vessel wall changes in the arterial system that can lead to many types of organ damage.

In this review the current scientific evidence on the diagnostics and treatment of large vessel vasculitis is evaluated and discussed.

In addition to the medical history and clinical presentation, imaging techniques nowadays represent the core of large vessel vasculitis diagnostics and have largely replaced the histological confirmation of GCA. After the diagnosis, acute treatment with glucocorticoids should be initiated as rapidly as possible but in the long term this should be tapered out or replaced by a steroid-sparing basic treatment. In contrast to GCA with already available options and other biologic disease-modifying antirheumatic drugs (DMARDs) about to be approved, there are still no approved biologic DMARD treatment options available for the less common TAK.

In contrast to the substantial progress in imaging diagnostics of large vessel vasculitis and with respect to the treatment of GCA, the much rarer TAK still requires intensive research efforts, especially to improve the treatment situation.
