Abstract

Objective: We aimed to detect novel in vitro effects of clopidogrel on platelets by assessment of the following parameters: malondialdehyde, glutathione, nitrite, aggregation response, and expressions of P-selectin, fibrinogen, apolipoprotein A1, apolipoprotein B, and phosphatidylserine. Materials and Methods: Platelets were obtained from healthy (n: 9) and hyperlipidemic (n: 9) volunteers. Expressions of P-selectin, fibrinogen, apolipoproteins A1/B and phosphatidylserine with and without clopidogrel were assayed by flow cytometry. Malondialdehyde, glutathione, aggregation and nitrite levels were also assayed. Results: Without clopidogrel, the baseline values of platelet aggregation, malondialdehyde, and expressions of P-selectin, fibrinogen and phosphatidylserine were significantly higher, whereas nitrite and expression of apolipoproteins A1/B were significantly lower in hyperlipidemics than in the healthy group. In both groups, clopidogrel significantly reduced aggrega- tion and expression of fibrinogen, but it elevated nitrite levels. Clopidogrel significantly decreased P-selectin and phospha- tidylserine expression and malondialdehyde but increased expressions of apolipoproteins A1/B only in hyperlipidemics. Conclusion: It seems that clopidogrel has some new in vitro antiplatelet effects. The present study is a basic in vitro study to suggest new insights into the effects of clopidogrel on platelet functions.

Özet

Amaç: Klopidogrelin trombositler üzerinde yeni in vitro etkilerini tayin etmek: Malondialdehit, glutatyon, nitrit, aggregasyon cevabı, P-selektin, fibrinojen, apolipoprotein A1, apolipoprotein B ve fosfatidilserin ekspresyonları. Yöntem ve Gereçler: Sağlıklı (n: 9) ve hiperlipidemik (n: 9) olgulardan trombositler elde edildi. Klopidogrelli ve klopidogrel- siz trombositlerde P-selektin, fibrinojen, apolipoprotein A1, apolipoprotein B ve fosfatidilserin ekspresyonları flow sitometre ile tayin edildi. Malondialdehit, glutatyon, aggregasyon ve nitrit seviyeleri de tayin edildi. Bulgular: Klopidogrel yokluğunda, hiperlipidemililerde kontrollere göre trombosit agregasyonu, malondialdehit, P-Selektin, fibrinojen ve fosfatidilserin ekspresyonunun başlangıç değerleri yüksek; bununla birlikte nitrit, apolipoprotein A1 ve apoli- poprotein B ekspresyonlarınınki ise daha düşüktü. Her iki grupta, klopidogrel anlamlı düzeyde aggregasyonu ve fibrinojen ekspresyonunu azalttı, fakat nitrit seviyelerini artırdı. Klopidogrel sadece hiperlipidemililerde P-selektin ve fosfatidilserin ekspresyonunu ve malondialdehiti azalttı ancak apolipoprotein A1 ve apolipoprotein B ekspresyonlarını artırdı. Sonuç: Görüldüğü üzere klopidogrel bazı yeni in vitro antiplatelet etkilere sahiptir. Bu çalışma, trombosit fonksiyonları üzeri- nde klopidogrelin etkilerine yeni bir bakış açısı sağlayan temel in vitro bir çalışmadır.
