Paper doi abstract bibtex Increased mean platelet volume (MPV) is an independent risk factor of thrombotic events in patients with cardiovascular diseases. Interactions of MPV with platelet aggregation activity and contents of glycoprotein (GP) IIb-IIIa (αIIb/β3 integrin, fibrinogen receptor) and GP Ib (von Willebrand factor recep- tor) have been investigated in this study. The study was performed in a group of healthy volunteers (n = 38) and a group of patients with acute coronary syndrome (ACS, n = 116). Patient's blood was collected at days 1, 3-5 and 8-12 after ACS development. All patients received acetylsalicylic acid (ASA, inhibitor of thrombox-ane A2 synthesis) as the antiaggregant therapy and most of them also received clopidogrel (ADP receptor antagonist), except 44 patients who had not taken clopidogrel at day 1 before first blood collection. Aggrega-tion of volunteers' platelets was stimulated by 1.25, 2.5, 5 and 20 μM ADP, while aggregation of patients' platelets was stimulated by 5 and 20 μM ADP. GP IIb-IIIa and GP Ib content on the platelet surface was measured using 125I-labelled monoclonal antibodies. GP IIb-IIIa and GP Ib genetic polymorphisms were determined in ACS patients. In healthy donors significant correlations between MPV and aggregation levels have been recognized at 1.25 μM and 2.5 μM ADP (correlation coefficient (r) values of 0.396 and 0.373, p < 0.05), while at 5 μM and 20 μM ADP these interactions did not reach the level of statistical significance (r values of 0.279 and 0.205, p > 0.05). Correlations between MPV and aggregation levels were observed at day 1 of ACS in a subgroup of patients receiving ASA but before the beginning of clopidogrel treatment (r values of 0.526, p < 0.001 and 0.368, p < 0.05 for 5 and 20 μM ADP, respectively). Correlations between these parameters were not found during combined treatment of patients with ASA and clopidogrel. Strong direct correlations between MPV and GP IIb-IIIa and GP Ib contents were detected in both healthy donors and ACS patients (at all time points): the r values ranged from 0.439 to 0.647 (p ≤ 0.001 for all correlations). Genetic polymorphisms of GP IIb-IIIa (GP IIIa Leu33Pro) and GP Ib ((-5)T/C (Kozak) and Thr145Met) identified in ACS patients did not affect expression levels of corresponding glycoproteins. The data obtained indicate that increased MPV values correlate with increased platelet aggregation activity and enhanced GP IIb-IIIa and GP Ib expression. © Pleiades Publishing, Ltd., 2014.
