Implication

Platelet kinetics in asplenia warrant cautious clinical use; leaves open validation of liver and marrow clearance in larger studies.

Structured PICO

What is the survival and tissue distribution of 111Indium-oxine labelled autologous platelets in asplenic subjects?

P
Population
4 asplenic subjects
I
Intervention
111Indium-oxine labelled autologous platelets
C
Comparator
Normal subjects
O
Outcome
Platelet survival, tissue distribution, and fatesurrogate

This study demonstrates that in the absence of a spleen, senescent platelets are primarily destroyed in the liver and bone marrow, exhibiting a linear survival curve.
