Aim: The aim of this study was to investigate the role of elevated glycated LDL (low-density lipoprotein) in the progression of diabetic kidney disease among type 2 diabetes (T2D) subjects.
Materials And Methods: This case-control observational study is a part of Saudi Diabetes Kidney Disease (SAUDI-DKD) study conducted during the period from April 2014 to June 2015. This study cohort is divided into two groups; the first group was T2D patients without diabetic nephropathy (DN) (n = 24) and the second group was T2D with DN (n = 45). Serum glycated LDL levels were determined by ELISA. Pearson's correlation analysis was performed, and the diagnostic accuracy was assessed using the area under the ROC curve.
Results: There was a threefold increase of serum glycated LDL level among diabetic subjects when compared with non-diabetic subjects and this level progressively increased with the progression of DN. The glycated LDL was found to have a significant diagnostic accuracy with AUC of 0.685 and 0.775 for cases with microalbuminuria and macroalbuminuria respectively.
Conclusion: The glycated LDL could play a significant role in predicting diabetic patients who are susceptible to develop DN among T2D patients.

Background: Advanced glycation end product-modified low-density lipoprotein (AGE-LDL) is related to inflammation and the development of atherosclerosis. Additionally, it has been demonstrated that receptor for advanced glycation end products (RAGE) has a role in the condition known as calcific aortic valve disease (CAVD). Here, we hypothesized that the AGE-LDL/RAGE axis could also be involved in the pathophysiological mechanism of CAVD.

Low-density lipoprotein (LDL) transports cholesterol to various tissues via the blood. Glycation of LDL occurs during hyperglycemic condition which is characterised by persistently high blood glucose level. Circulating erythrocytes can come in direct contact with glycated LDL (G-LDL).

Background & Aims: Glycation, oxidative stress, and inflammation due to the elevation of transforming growth factor-β1 (TGF-β1) participate in diabetic nephropathy (DN). Thus, we investigated for the first time the effect of crocetin (Crt) on the renal histopathological parameters, TGF-β1 and glycation, oxidative stress, as well as inflammatory markers in the DN rat model.
Methods: Forty male Wistar rats were randomly divided into 4 equal groups: normal (N), N + Crt, DN, and DN + Crt.

Atherosclerosis, the pathological basis of most cardiovascular diseases, is a main risk factor causing about 20 million deaths each year worldwide. Oxidized low-density lipoprotein is recognized as the most important and independent risk factor in initiating and promoting atherosclerosis. Numerous antioxidants are extensively used in clinical practice, but they have no significant effect on reducing the morbidity and mortality of cardiovascular diseases.
