To investigate the effect of moderate alcohol consumption on blood constituents related to cardiovascular disease, 12 male volunteers consumed (instead of their usual alcoholic drinks) four different standardized amounts of red wine in addition to their habitual diet. Each dose was given to the subjects during a period of 5 weeks in a randomized order, all subjects receiving the four doses. They consisted of 0, 2, and 4 glasses/d, providing 0, 23, and 46 g alcohol/d as well as in "binge drinking" (14 glasses in the weekend, comparable to an average of 2 glasses/d). The results showed a clear dose-related response to the drinking for several blood constituents. Most marked was a decrease in the tissue-type plasminogen activator activity and to a lesser degree an increase in plasminogen levels. Collagen-induced platelet aggregation was reduced, affecting all parameters measured. Levels of HDL3-cholesterol, gammaglutamyltransferase, and urate showed a small but significant increase. No change was noted in the levels of alkaline phosphatase, alanine-aminotransferase, aspartate-aminotransferase, bile acids, folate, fibrinogen, the ADP-induced platelet aggregation, platelet secretion, or in hematologic values. The results are only partially in accordance with the presumed protective action of moderate drinking on the cardiovascular system and show a stronger response to the consumption of alcohol in coagulation and fibrinolysis factors than in blood lipids.

A randomized double-blind study was carried out with gemfibrozil (600 mg b.i.d.) vs placebo in 20 patients (twelve males and eight females, age 52 +/- 3 years, BMI 24.2 +/- 0.4) suffering from primary hypertriglyceridemia (Fredrickson's type IV). Each group was treated for a 12 week period with gemfibrozil (n = 10) or placebo (n = 10) patients) in a double-blind fashion. Total cholesterol, HDL-cholesterol (HDL-C) and its subfractions (HDL2-C and HDL3-C), blood glucose, Apolipoproteins A1 and B, fibrinogen, plasminogen, factor VII, t-PA:Ag and PAI activity pre- and post-venous occlusion (VO) were determined. In the gemfibrozil-treated group a significant decrease of total cholesterol and triglycerides and a significant increase of HDL-C and HDL2-C were found. During gemfibrozil treatment a significant reduction of factor VII, fibrinogen and plasminogen levels was also observed. After 12 weeks of treatment in the gemfibrozil group the release of t-PA:Ag in response to venous occlusion was significantly higher and plasma PAI activity was significantly lower than in placebo group. Moreover positive correlations between HDL cholesterol and t-PA:Ag post-VO (r = 0.56, P < 0.01) and between HDL2-C cholesterol and t-PA:Ag post-VO (r = 0.59, P < 0.01) and a negative correlation between triglycerides and t-PA:Ag post-VO (r = -0.65, P < 0.01) were found. The data obtained suggest that gemfibrozil, in addition to the well established lipid-regulating effect, appears to have a positive role in the regulation of reverse cholesterol transport and fibrinolytic system.

Elevated levels of endogenous tissue-type plasminogen activator (t-PA) appear to be a marker for preclinical atherosclerosis. At present, however, data describing potential relations between plasma t-PA level and established lipid risk factors for coronary atherosclerosis are sparse. To explore these potential relations, we measured plasma levels of t-PA antigen (t-PA:ag) in 633 apparently healthy men in the Physicians' Health Study as well as total cholesterol, high-density lipoprotein (HDL) cholesterol, HDL2 cholesterol, HDL3 cholesterol, and apolipoproteins A-I, A-II, and B-100. Overall, plasma t-PA:ag levels were inversely correlated with HDL cholesterol (r = -.1616, P < .0005), HDL2 cholesterol (r = -.1632, P < .0005), and HDL3 cholesterol (r = -.0927, P = .019). In stratified analyses, the inverse association between t-PA:ag and HDL cholesterol was present among frequent (P trend = .002) and infrequent (P trend = .004) consumers of alcohol as well as among the subgroups of frequent exercisers (P trend < .001), men in the lower half of body mass index (P trend = .001), and nonsmokers (P trend < .001). In contrast, there was no association between t-PA:ag and total cholesterol (r = .0219, P = .58), whereas relations of t-PA:ag with apolipoproteins A-I, A-II, and B-100 were minimal and of borderline significance. These data indicate that plasma levels of endogenous t-PA:ag are inversely related to HDL cholesterol as well as HDL2 and HDL3 cholesterol.(ABSTRACT TRUNCATED AT 250 WORDS)
