Druggability of lipid metabolism modulation against renal fibrosis

Renal fibrosis contributes to progressive damage to renal structure and function. It is a common pathological process as chronic kidney disease develops into kidney failure, irrespective of diverse etiologies, and eventually leads to death. However, there are no effective drugs for renal fibrosis treatment at present. Lipid aggregation in the kidney and consequent lipotoxicity always accompany chronic kidney disease and fibrosis. Numerous studies have revealed that restoring the defective fatty acid oxidation in the kidney cells can mitigate renal fibrosis. Thus, it is an important strategy to reverse the dysfunctional lipid metabolism in the kidney, by targeting critical regulators of lipid metabolism. In this review, we highlight the potential "druggability" of lipid metabolism to ameliorate renal fibrosis and provide current pre-clinical evidence, exemplified by some representative druggable targets and several other metabolic regulators with anti-renal fibrosis roles. Then, we introduce the preliminary progress of noncoding RNAs as promising anti-renal fibrosis drug targets from the perspective of lipid metabolism. Finally, we discuss the prospects and deficiencies of drug targeting lipid reprogramming in the kidney.

Pharmacological Management of Diabetic Nephropathy

INTRODUCTION

Diabetes mellitus (DM) is one of the most common diseases worldwide. Its adverse effects on several body organs, have made treatment of DM a priority. One of the most serious complications of DM is diabetic nephropathy (DN).

OBJECTIVE

The aim of this review is to critically discuss available data on the pharmacological management of DN.

METHODS

A comprehensive review of the literature was performed to identify studies assessing the impact of several drug classes on DN.

RESULTS

Several studies have been conducted in order to find a novel and effective treatment of DN. So far, the cornerstone therapy of DN consists of renin-angiotensin system (RAS) inhibitors, agents that decrease the synthesis of intrarenal angiotensin II or block its receptors. Their antiproteinuric and antihypertensive effects can not only decelerate the progress of DN but prevent its onset as well. Novel antidiabetic drugs, such as sodium-glucose cotransporter 2 inhibitors (SGLT-2i) and glucagon-like peptide- 1 receptor agonists (GLP-1 RA), are promising agents in the therapy of DN, due to their positive effect on renal and cardiovascular adverse events. From lipid-lowering agents, atorvastatin improves DN up to stage 3 and substantially reduces CVD.

CONCLUSION

RAS inhibitors, SGLT-2i and GLP-1 agonists were found to be beneficial for the treatment of DN. Larger renal trials are needed in order to incorporate these drugs into the first line treatment of DN.
