Riesenzellarteriitis: Aktuelle Erkenntnisse zu Epidemiologie, Pathogenese, Diagnostik und Therapie

Abstract: ZusammenfassungAls Riesenzellarteriitis (RZA, englisch giant cell arteritis, GCA) bezeichnet man eine Vaskulitis der großen Gefäße, also der Aorta sowie der aortennahen Gefäße erster und zweiter Ordnung. RZA sind in Manifestation und Verlauf vielgestaltige Erkrankungen, die häufig hohe Ansprüche an die Diagnostik und die langfristige Betreuung der Patienten stellen. Fortschritte in Ultraschall-, MRT- und Positronen-Emissionstomografie haben die Diagnostik erleichtert und den Blick für seltenere und ungewöhnlic… Show more

“…Scalp necrosis as initial manifestation of the disease is rare but is associated with increased mortality and loss of vision. 1,2,[8][9][10] Performing a scalp reconstruction via large skin rotation flaps under high immunosuppressive therapy might show higher complication rates and increase the risk for severe infections. 5,9 Although high dose immunosuppressants during extensive dermatosurgical procedures may seem counterintuitive, in our case the therapy was essential to avoid an exacerbation of the underlying GCA disease, and, in combination with intravenous antibiotic prophylaxis, to enable successful wound healing (Figure 3).…”

“…Giant cell arteritis is a granulomatous inflammation of aortic vessels and is the most common systemic vasculitis in the age group > 50 years. 1,2 Pathogenetically, Th1 and Th17 signaling pathways, myofibroblasts as well as macrophages are activated via Toll-like receptors, altogether increasing the expression of proinflammatory cytokines such as Interleukin-6 and -17. As a result of the T cell-based immune response and macrophage activation, inflammation of the adventitia occurs with destruction of elastic fibers and myointimal hyperplasia.…”

“…Die Riesenzellarteriitis ist eine granulomatöse Entzündung der Aorta und der aortennahen Gefäße und ist die häufigste systemische Vaskulitis in der Altersgruppe der über 50-Jährigen. 1,2 Pathogenetisch werden Th1-und Th17-Signalwege, Myofibroblasten sowie Makrophagen über Toll-like-Rezeptoren aktiviert, welches insgesamt die Expression von proinflammatorischen Zytokinen wie Interleukin-6 und -17 erhöht. Infolge der T-Zell-basierten Immunantwort und der Makrophagenaktivierung kommt es zu einer Entzündung der Adventitia mit Zerstörung der elastischen Fasern sowie myointimaler Hyperplasie.…”
