We will discuss potential mechanism of these effects, the differences between various DPP-4 inhibitors, and future perspectives of its use in patients with diabetic kidney disease. Angiotensin-converting enzyme inhibitor AGEs: View at Google Scholar K.
Preclinical data suggesting nephroprotective effects of DPP-4 inhibitors are available for sitagliptin [ 46 ], vildagliptin [ 47 ], and linagliptin [ 48 ]. International Journal of Endocrinology.
Since the launch of sitagliptin ina compelling body of evidence has accumulated showing that dipeptidyl peptidase-4 DPP-4 inhibitors, which augment endogenous GLP-1 and GIP levels, represent an important advance in the management of T2DM. Revisiting the clinnical between type 2 diabetes, weight gain, and cardiovascular risk.
DPP-4 inhibitors: what may be the clinical differentiators?
After 6 months of sitagliptin treatment, albuminuria measured by urinary albumin creatinine ratio UACR significantly decreased both in the patients with relatively modest microalbuminuria and the patients with more pronounced microalbuminuria at baseline. The study with vildagliptin was performed on rats with streptozotocin-induced diabetes.
Preclinical Data of DPP-4 Inhibitors with Nephroprotective Outcomes Preclinical data suggesting nephroprotective effects of DPP-4 inhibitors are available for sitagliptin [ 46 ], vildagliptin [ 47 ], and linagliptin [ 48 ].
View at Google Scholar A. Sitagliptin significantly lowered HbA1c and systolic and diastolic blood pressure. The endpoint of the analysis was the percentage change in geometric mean of UACR after 24 weeks of treatment compared to baseline values. This therapeutic diversity should help clinicians tailor inihbitors to the individual patient, thereby increasing the proportion that safely attain target HbA 1c levels, and reducing morbidity and mortality.
Several other DPP-4 inhibitors, including linagliptin and alogliptin, are currently in clinical development. In addition to pancreas, GLP-1 receptor GLP-1R is expressed in other numerous tissues including glomerular endothelial cells, mesangial cells, podocytes and also proximal tubular cells. Glomerular filtration rate GLP Numerous studies have shown that the risk of diabetic kidney disease is tightly linked to poor glucose control in both type 1 and type 2 diabetes [ 1011 ].

Furthermore, numerous ongoing long-term cardiovascular trials with DPP-4 inhibitors can bring novel crucial information about relationships among glucose control and macrovascular and microvascular complications and further elucidate the role of albuminuria in these processes.
Plasminogen activator inhibitor-1 PKA: Stimulation of GLP-1 receptor in turn increases insulin secretion and suppresses excessive glucagon release leading to improved glucose control. Proven additive effect of any antihyperglycemic agent on albuminuria lowering would be therefore of a high interest.
Possible mechanisms underlying these effects include reduction of oxidative stress and inflammation and improvement of endothelial dysfunction in the kidney. In this study, vildagliptin was administered intravenously 15 minutes before surgery, and animals were sacrificed after 2, 12, and 48 hours of reperfusion.
On the other hand, DPP-4 inhibitors have different pharmacokinetics, and their nonglucose lowering effects may vary in man due to different concentrations in innhibitors organs diffefentiators due to distinct substrate selectivity of binding to DPP-4 enzyme [ 57 ].
This review offers diffefentiators overview of DPP-4 inhibitors in T2DM and suggests some characteristics that may provide clinically relevant differentiators within this class. Glycemic control with diet, sulfonylurea, metformin, or insulin in patients with type 2 diabetes mellitus: The total systemic glycocalyx volume is reduced by acute hyperglycemia in humans [ 20 ].
Upregulation of DPP-4 expression in renal glomeruli occurs during inflammation and usually accompanies the development of diabetes-induced glomerulosclerosis [ 6 ].
Renal Effects of DPP-4 Inhibitors: A Focus on Microalbuminuria
Predictors of medication nonadherence among patients with diabetes in Medicare Part D programs: These data suggest that the nephroprotection by DPP-4 inhibition was mediated by antiapoptotic, anti-inflammatory, and antioxidative changes. Diabetes was induced in endothelial nitric oxide synthase eNOS knockout mice which were used as an experimental model of nephropathy [ 48 ].
Podocyte loss is one of the first changes contributing to increased glomerular permeability for albumin. The presence of microalbuminuria represents an important early sign of kidney damage in patients with diabetes [ 16 ].
