Abstract:
:Previous work has shown that cigarette-smoking affects platelets and endothelium in men and women without renal failure. The present study compared 10 male habitual smokers receiving maintenance hemodialysis for chronic renal failure with 11 healthy male habitual smokers before and after controlled cigarette-smoking after a 12-hour period of abstinence. Collagen-induced platelet aggregation was not significantly different in the two groups of men before smoking. The platelet aggregate ratio was lower and the plasma concentration of platelet factor 4 was higher in the dialysis patients than in the healthy men (p < 0.05). Mean or median values before and after cigarette smoking by the dialysis patients were 42 and 62 chart units for collagen-induced platelet aggregation, 0.88 and 0.77 for the platelet aggregate ratio, 6.2 and 8.5 ng/ml for the plasma concentration of platelet factor 4, 0.8 and 1.7 per counting chamber for the endothelial cell count and 4 and 37 ng/ml for the plasma nicotine concentration (each p < 0.01). None of the changes which occurred in the dialysis patients was statistically significantly different from those in the healthy men. We conclude that cigarette-smoking has similar effects on platelets and endothelium in patients receiving maintenance hemodialysis and in healthy controls.
