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.

Factors Affecting Erythropoiesis
Several factors influence the erythrocyte production rate, with tissue oxygen level being among the most critical. Intense exercise or high altitudes can cause tissue hypoxia, which triggers the kidneys to release more erythropoietin (EPO) into the bloodstream.
