Diagnostik und Therapie der Polycythaemia vera im Jahre 2015
Diagnosis and treatment of polycythemia vera in the year 2015Publikationsverlauf
Publikationsdatum:
07. Oktober 2015 (online)

-
Neue Entwicklungen bei Diagnosesicherung und Pathogenese: Hauptkriterien der zur Zeit noch aktuellen WHO-Klassifikation der Polycythaemia vera (PV) sind eine gesteigerte Erythrozytenmasse und der Nachweis eines klonalen Markers (JAK2-Mutation).
-
Klinische Symptome: Der Schweregrad der PV-Symptome ist häufig moderat, jedoch leiden viele Patienten an mehreren Symptomen, wodurch die Lebensqualität eingeschränkt ist.
-
Therapieziele und Risikostratifizierung: Bei in der Regel guter Überlebensprognose ist die Reduktion der potenziell bedrohlichen thromboembolischen Komplikationen primäres Therapieziel. Das Überleben wird signifikant von der Anzahl der vorliegenden Risikofaktoren beeinflusst.
-
Therapie: Aderlass, ASS und zytoreduktive Therapie (Hydroxyurea bzw. Interferon-alpha) sind die Eckpfeiler der Therapie. Der Tyrosinkinase-Inhibitor Ruxolitinib erweitert die Therapiemöglichkeiten bei einer Resistenz und Intoleranz gegenüber Hydroxyurea.
