Effect of moderate wine consumption on the activity of enzymes involved in platelet-activating factor metabolism and thrombotic biomarkers: a randomised, single-blind, parallel, clinical study in CHD men patients
Published online by Cambridge University Press: 13 February 2025
Abstract
A randomised parallel intervention study was conducted with male patients diagnosed with CHD. Participants were assigned to three groups: Group A abstained from alcohol (n 20), Group B consumed red wine (n 21) and Group C (n 16) consumed an alcoholic beverage without wine micro-constituents. Biological samples were collected at baseline, 4 and 8 weeks. Enzyme activities of acetyl-CoA:lyso-platelet-activating factor (PAF) acetyltransferase, cytidine 5’-diphospho (CDP)-choline:1-alkyl-2-acetyl-sn-glycerol cholinephosphotransferase (PAF-cholinephosphotransferase), PAF-acetylhydrolase in leukocyte homogenates, serum lipoprotein-associated phospholipase-A2 and plasma markers of thrombosis were measured. PAF-, ADP- and collagen-induced platelet aggregation was measured in human platelet-rich plasma. Red wine consumption led to a 15·3 % reduction in LysoPAF-acetyltransferase activity at 4 weeks (P= 0·008) compared with baseline and Group A (P= 0·01). PAF-cholinephosphotransferase activity was reduced by 11·1 % at 8 weeks (P= 0·04) compared with baseline and by 24·9 % compared with Group C (P= 0·02). PAF-acetylhydrolase activity was reduced by 36·2 % at 8 weeks compared with baseline (P= 0·001) and compared with Group A (P< 0·000) and Group C (P= 0·009). Fibrinogen levels in Group B reduced by 6–9 % at 4 (P= 0·04) and 8 weeks (P= 0·01) compared with baseline while D-dimer in Group C increased by 16·1 % at 8 weeks (P= 0·005) compared with baseline. Platelet aggregation against PAF and collagen was reduced in Group B (82·6 and 35·4 %, respectively), and in Group C (158·4 and 37·1 %, respectively) compared with baseline and Group A (P< 0·05). In conclusion, moderate wine consumption improved the activity of PAF-metabolism enzymes regardless of ethanol and reduced platelet aggregation, probably through mechanisms different from those of ethanol.
