Background And Aim:
This study was designed to clarify the impact of the short-term consumption of different types of alcoholic beverages on haemostatic factors, C-reactive protein (hsCRP) and endothelin-1 (E-1) plasma levels.
Methods:
The study group consisted of 57 healthy male volunteers, aged 20-29 years. Subjects were randomised to consume 300 mL of red wine, white wine, 12% ethanol, black currant juice or water for five days. Blood samples were collected for CRP, tissue type plasminogen activator antigen (t-PA:Ag), plasminogen activator inhibitor antigen (PAI-1:Ag) and E-1 at baseline, on day 2, and on day 6.
Results:
A significant increase in PAI-1:Ag concentration was observed in the red wine drinking group (day 1: 44.98; day 2:56.86; day 6: 47.44 ng/mL; p = 0.05). A similar increase of E-1 level was found in the 12% ethanol group (day 1: 0.53; day 2:1.65; day 6: 1.11 fmol/mL; p = 0.01). Dividing the whole study group according to ethanol content of consumed beverages revealed significant changes in tPA:Ag, PAI-1:Ag and E-1 levels. In the alcohol drinking group, significant increases of PAI-1:Ag (day 1: 44.75; day 2: 54.07; day 6: 44.80 ng/mL; p < 0.05); tPA:Ag level (day 1: 3.65; day 2: 4.17; day 6: 5.03 ng/mL;p < 0.02) and E-1 (day 1: 0.42; day 2: 1.01; day 6: 0.97 fmol/mL; p < 0.002) were observed.
Conclusions:
Short-term alcohol consumption increases tPA:Ag, PAI:Ag and E-1 plasma levels. This effect may have an unfavourable impact on the fibrinolytic system and endothelial function.
