Microvesicle-bound DPP-4 secreted from tubular epithelial cells is found in urine and may be an early marker of renal damage before the onset of albuminuria [ 31 ]. The study with vildagliptin was performed on rats with streptozotocin-induced diabetes. In addition to being a marker of renal damage, albuminuria has emerged as a predictive marker of increased risk of cardiovascular disease [ 51 ].

DPP-4 inhibitors: what may be the clinical differentiators?

In this study, vildagliptin was administered intravenously 15 minutes before surgery, and animals were sacrificed after 2, 12, and 48 hours of reperfusion.

Diabetic kidney disease DPP At the moment, the data are too scarce and incomplete to make definite conclusions with respect to DPP-4 inhibitors induced nephroprotection. Attenuation of the prandial incretin effect, mediated by glucagon-like peptide-1 GLP-1 and glucose-dependent insulinotropic peptide GIPcontributes to hyperglycemia in type 2 diabetes mellitus T2DM. Here, we review the renal effects of DPP-4 inhibitors with special focus on its influence on the onset and progression of microalbuminuria, as presence of microalbuminuria represents an important early sign of kidney damage and is also associated with increased risk of hypoglycemia and cardiovascular complications.

Furthermore, two small studies with sitagliptin and the experimental studies described previously open the possibility that nephroprotection might be a class effect of DPP-4 inhibition.

CKD stage 1 is characterized by normal GFR and urine findings mostly albuminuria difcerentiators structural abnormalities of the kidney. According to current guidelines, the primary intervention in patients with detected albuminuria is the blockade of renin-angiotensin-aldosterone system RAAS with an angiotensin-converting enzyme inhibitor ACEi or angiotensin II receptor blocker ARB [ 52 ].


DPP-4 inhibitors for type 2 diabetes: The results inhibtors published preclinical and clinical studies suggest that DPP-4 inhibitors may have a potential to lower albuminuria and to also possess other more complex nephroprotective properties.

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. Diabetic and controls rats were treated with sitagliptin or vehicle for 6 weeks.

Stimulation of GLP-1 receptor in turn increases insulin secretion and suppresses excessive glucagon cllnical leading to improved glucose control. The expanding evidence base also suggests that certain differences between DPP-4 inhibitors may prove to be clinically significant.

These results suggest that metformin does not share the albuminuria-lowering potential of thiazolidinediones and incretin-based therapies [ 60 ]. We performed a primary Medline search using combinations of keywords: After 12 weeks of administration, linagliptin or telmisartan had no effect on glycemic control, while telmisartan reduced systolic blood pressure by 5.

Light and electron microscopies of renal tissue revealed that vildagliptin treatment dose dependently inhibited interstitial expansion, glomerulosclerosis, and thickening of the glomerular basement membrane [ 47 ].

These therapeutics either increase concentrations of endogenous glucagon-like peptide-1 GLP-1 by the inhibition of its degradation dipeptidyl peptidase-4 inhibitors or directly stimulate GLP-1 receptor GLP-1 receptor agonists [ 4 ].

Antidiabetic treatment with gliptins: These data suggest that the nephroprotection by DPP-4 inhibition was mediated by antiapoptotic, anti-inflammatory, and antioxidative changes.

This therapeutic diversity should help clinicians tailor treatment to the individual patient, thereby increasing the proportion that safely attain target HbA 1c levels, and reducing morbidity and mortality. Nevertheless, larger trials designed primary on testing renal onhibitors are necessary to confirm this interesting possibility.

Non-insulin dependent diabetes mellitus: 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.

Lobb Clinical therapeutics Its levels correlate with the degree of mesangial expansion, interstitial fibrosis, and renal dysfunction, but not with the extent of microalbuminuria [ 25 differentiaotrs.

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. This decrease was prevented by treatment with vildagliptin. Streptozotocin-induced diabetes was used also in an experimental study with linagliptin [ 48 ].
