The disease progresses without obvious symptoms and is often refractory when apparent symptoms have emerged. Although the molecular mechanisms underlying the onset/progression of DKD have been extensively studied, only a few effective therapies are currently available. Pathogenesis of DKD involves multifaced events caused by diabetes, which include alterations of metabolisms, signals, and hemodynamics. While the considerable efficacy of sodium/glucose cotransporter-2 (SGLT2) inhibitors or angiotensin II receptor blockers (ARBs) for DKD has been recognized, the ever-increasing number of patients with diabetes and DKD warrants additional practical therapeutic approaches that prevent DKD from diabetes. One plausible but promising target is the mechanistic target of the rapamycin complex 1 (mTORC1) signaling pathway, which senses cellular nutrients to control various anabolic and catabolic processes.

There are three methods for measuring ketone bodies. Urine ketone analysis (AcAc) is a standard clinical test, whereas blood ketone testing (BHB+AcAc) is valuable in identifying or resolving diabetic ketoacidosis. Recently, technology for measuring breath acetone has been introduced, which provides an easy means of monitoring ketogenic diets in obese individuals. The basic breath alcohol detector also reacts with breath acetone. Therefore, it is important for professional drivers taking SGLT2 inhibitors to be cautious as workplace breath alcohol detectors may show false-positive results.
