The present paper describes a flow cytometric method for assay of platelet activation and provides
information important in identifying and differentia
ting thrombogenic states in patients with primary
antiphospholipid syndrome (SAFP).
Objectives:to evaluate the significance of platelet ac
tivation markers for the evolution with venous
and arterial recurrent thrombosis
in patients (pts). with SAFP.
Methods: 14 pts. with SAFP diagnosed according to
revised Sapporo classification for APS criteria,
mean age .47.87(18-74) years,7 women and 7men, were
followed 24 month for the evolution with recurrent
thrombosis. The expression of platelet activation markers CD62P (Pselectin) and CD40L were assesed using
standardised flow cytometric method (Becton Dickins
on) at baseline and after 12 months. Statistics: The
results are shown as mean ± SD. Paired t tests were used for statistical comparisons.
Results:
No significant correlation was observed between expression of platelet activation markers
CD62P (Pselectin) and CD40L in patients with histor
y of recurrent thrombosis and SAFP patients without
recurrent thrombosis. One single patient from six pts. had a acute trombotic event during follow-up
expressed markers of platelet activation.
Conclusions: Platelet activation markers in flow-citometry did not correlated with reccurent
thrombosis and acute thrombosis in pts. with SAFP.
