Summary
Advanced glycation products (AGEs) are compounds formed by the addition of sugars to amino acids (the building blocks of proteins). The addition of sugars to proteins induces biological changes that have been implicated in the development of diabetic complications, especially diabetic kidney disease. AGEs are a diverse group of compounds and to date the exact role that specific AGEs play in the causation of diabetic kidney disease is still unclear. However, new methods are now available that all ....Advanced glycation products (AGEs) are compounds formed by the addition of sugars to amino acids (the building blocks of proteins). The addition of sugars to proteins induces biological changes that have been implicated in the development of diabetic complications, especially diabetic kidney disease. AGEs are a diverse group of compounds and to date the exact role that specific AGEs play in the causation of diabetic kidney disease is still unclear. However, new methods are now available that allow the comprehensive quantification of individual AGE levels in blood. Our study involves the comparison of AGE blood levels, as a group or as specific AGEs with markers of diabetic kidney disease such as albumin (protein) excretion in the urine and the rate that the kidney filters the blood to form urine (glomerular filtration rate). Benfotiamine is a thiamine (vitamin B1) derivative that has been shown to decrease the formation of AGEs and to prevent kidney disease in diabetic animals. The present clinical study will assess whether benfotiamine has similar effects on AGEs and kidney disease in patients with type 2 diabetes. If successful, this study has the potential to provide a new treatment strategy for diabetic kidney disease in humans.Read moreRead less

Summary
High levels of sugars seen in patients with diabetes leads to damage of many organs including the heart, the eyes and the kidneys. These high sugars cause damage through a number of mechanisms, one being the formation of advanced glycation end products or AGEs, formed by the irreversible reaction between proteins and glucose. This reaction leads to a change in the shape and function of AGE-modified molecules that progressively contributes to organ damage. AGEs also bind and activate specific rec ....High levels of sugars seen in patients with diabetes leads to damage of many organs including the heart, the eyes and the kidneys. These high sugars cause damage through a number of mechanisms, one being the formation of advanced glycation end products or AGEs, formed by the irreversible reaction between proteins and glucose. This reaction leads to a change in the shape and function of AGE-modified molecules that progressively contributes to organ damage. AGEs also bind and activate specific receptors that promote the damage and scarring of tissue. Where the glucose concentration is high, AGEs accumulate much more quickly. This is one reason why patients with good sugar control do better than those who are unable to control their blood sugars. The importance of this AGE pathway is illustrated by the fact that blocking the formation of AGEs is able to prevent kidney damage in animals with diabetes. In addition, exposure to AGEs can cause diabetes-like changes in the absence of high sugars. Our laboratory is a world leader in the study of the advanced glycation and methods blocking this process. The research proposed will investigate circulating levels of AGEs in experimental animals and patients with diabetes, and correlate them with the development and progression of complications of diabetesRead moreRead less
