Abstract: BACKGROUND: This study examines the relationship between circulating advanced glycated end products (AGEs) level and erythrocyte osmotic fragility in smokers. METHODS: Forty-eight smokers (aged 45 ± 5 years) and fifty healthy nonsmokers (aged 42 ± 6 years) were selected in this study. All subjects were analysed according to serum AGEs, osmotic fragility (H50, the NaCL concentration producing 50% hemolysis), malondialdehyde (MDA) and advanced oxidation protein products (AOPP). RESULTS: The data show that the serum AGEs, H50, MDA and AOPP levels were significantly higher for smokers than that of nonsmokers (p < 0.01). The serum AGEs correlated with H50 in smokers (r = 0.7703, p < 0.01). MDA levels correlated with H50 in smokers (r = 0.7584, p < 0.01). CONCLUSIONS: This study demonstrated that serum AGEs and MDA levels positively correlated with osmotic fragility in smokers.
