[myeloproliferative] Flashcards
RBCs
Platelets
Fibroblasts
WBCs
polycythaemia vera
essential thrombocythaemia
CML
myelofibrosis
relative (normal RBC mass, low plasma)
polycythaemia rubra vera
Hypoxia (e.g. altitude)
inappropriate EPO secretion
JAK2
platelets
WBCs
hyperviscosity
fingers
toes
(aka erythromyalgia)
hot temperatures
“after hot bath”
increased RBC turn over therefore release of yrate
thrombus
CML
polycythaemia rubra vera
myelofibrosis
essential thrombocytopaenia
raised
hypercellularity
erythroid hyperplasia
Radioactive chromium-51 - shows RBC mass
normal O2 partial pressure
raised red cell mass on chromium-51 Ix
low
venesection
hydroxycarbamide
