Abstract

Aim The advanced glycation end products (AGEs) are among the mechanisms responsible for the pathogenesis and development of chronic kidney disease. The aim of this study was to estimate the dietary AGE intake and to assess its correlation with hematological and biochemical markers of patients with end-stage renal disease (ESRD) undergoing hemodialysis. Materials and methods For this study, a structured questionnaire of the exogenous AGEs was developed, whose reliability and validity were evaluated in the pilot phase of the study including 50 participants. The questionnaire was issued to 605 participants (305 ESRD patients undergoing hemodialysis and 300 controls), and a blood sample was obtained through which hematological and biochemical markers were analyzed. Results It was noted that patients with ESRD consume large quantities of dietary AGEs not only in absolute values but also in comparison with control subjects (p = 0.001), attributed mainly to the methods of product processing as well as cooking. It was also ascertained that dietary AGEs were correlated (p < 0.005) with fasting glucose and glycated hemoglobin (HbA1c) and with lipidemic profile markers, such as triglyceride, as well as inflammation markers, such as erythrocyte sedimentation rate, ferritin, and C-reactive protein. All the aforementioned markers show abnormally increased levels in patients with ERSD and diabetes compared with healthy subjects. Conclusion Patients with ESRD consuming foods favoring AGE formations combined with increased endogenous AGE burden the body with their harmful action. If the specific group of patients adopt dietary habits contributing to the containment or the inhibition of AGE formation, then this would lead to the improvement of their hematological and biochemical markers and in terms of the effects of AGEs on their health is deemed imperative through the creation of consulting and prevention programs.
