Detection of proinflammatory cytokines such as TNF-alpha, IL-3, IL-6 as well as the expression of adhesion molecules (VCAM-1, ICAM-1) in the vessel walls.
TherapyThis section has been translated automatically.
Avoid triggering mechanisms as far as possible. The only effective therapy is the administration of systemic glucocorticoids such as prednisolone (e.g. Decortin H) initially 50-80 mg/day, with the lowest possible maintenance dose. Antihistamines are generally ineffective.
