Klinische bewertung potentieller einsatzbereiche von rekombinantem faktor VIIa bei internistischen und pädiatrischen erkrankungen: Empfehlungen einer expertensruppe

Recombinant factor VIIa (rFVIIa) is increasingly used outside the labeled indications for treatment of life-threatening bleeding episodes after failure of the respective standard therapy. An interdisciplinary group of experts summarizes the state of knowledge of the use of rFVIIa in gastroenterology and hepatology, thrombocytopenia and -pathia, coagulation factor deficiencies, von Willebrand's disease, periinterventional bleeding without specific bleeding diathesis, drug-induced bleeding, disseminated intravascular coagulation, and neonatology. The most commonly used dose is 90 μg/kg body weight rFVIIa as bolus, if necessary followed by additional injections at intervals of 2-3 h. In factor VII deficiency lower dosages of 15-30 μg/kg body weight of rFVIIa are given every 4-6 h, whereas higher doses of 150-200 μg/kg body weight are used in neonates.
