Implication

May impair erythrocyte deformability during platelet activation; leaves open whether acetylsalicylic acid preserves red-cell function in vivo.

Key Points

This research investigates how the activation of platelets impacts the deformability of erythrocytes.
Erythrocytes were suspended in autologous platelet poor plasma obtained from platelet rich plasma.
Deformability was measured after incubation with platelet activating substances like arachidonic acid, adrenaline, or ADP.
Malondialdehyde formation was assessed to indicate platelet activation.
Erythrocyte deformability was significantly reduced in the presence of activated platelets compared to controls.
Blocking endoperoxide formation with acetylsalicylic acid maintained erythrocyte deformability.
Plasma viscosity remained unchanged despite changes in platelet activation.

Structured PICO

Does platelet activation reduce erythrocyte deformability?

Population

Erythrocytes suspended in autologous platelet poor plasma (PPP) obtained from platelet rich plasma (PRP)

Intervention

Incubation of PRP with platelet activating substances (arachidonic acid, adrenaline, or ADP)

Comparator

PRP without platelet activating substances, or PRP treated with acetylsalicylic acid

Outcome

Erythrocyte deformabilitysurrogate

Platelet activation reduces erythrocyte deformability, an effect that can be prevented by cyclooxygenase inhibition with acetylsalicylic acid.
