Purpose of reviewDiabetic kidney disease is the most common cause of chronic kidney disease (CKD) and end-stage kidney disease in the world. Risk factor modification, glucose control, and renin–angiotensin–aldosterone system blockade have remained the standard of care for 2 decades. New therapeutic agents have emerged in recent years, demonstrating kidney and cardiovascular benefits, and herein we review recent clinical trials on this topic.Recent findingsAfter the publication of several cardiovascular outcome trials for sodium–glucose cotransporter 2 inhibitors (SGLT-2i), new trials have focused ON primary kidney-specific outcomes demonstrating safety and benefits among patients with proteinuric CKD; patients with or without diabetes, and heart failure with preserved ejection fraction (HFpEF) respectively. Similarly, nonsteroidal mineralocorticoid receptor antagonists (ns-MRAs) and glucagon-like-peptide 1 receptor agonists (GLP-1 RAs) have improved cardiovascular and kidney outcomes. Recently, clinical practice guidelines have also been updated to reflect this new evidence.SummaryIn summary, SGLT-2i, GLP-1 RAs, and ns-MRAs have demonstrated cardiovascular and kidney benefits, including all-cause and cardiovascular mortality, progression to end-stage kidney disease, and hospitalizations for heart failure exacerbation among diverse patient population.
Purpose of reviewMechanical circulatory support (MCS) is a group of evolving therapies used for indications ranging from temporary support during a cardiac procedure to permanent treatment of advanced heart failure. MCS is primarily used to support left ventricle function, in which case the devices are termed left ventricular assist devices (LVADs). Kidney dysfunction is common in patients requiring these devices, yet the impact of MCS itself on kidney health in many settings remains uncertain.Recent findingsKidney dysfunction can manifest in many different forms in patients requiring MCS. It can be because of preexisting systemic disorders, acute illness, procedural complications, device complications, and long-term LVAD support. After durable LVAD implantation, most persons have improvement in kidney function; however, individuals can have markedly different kidney outcomes, and novel phenotypes of kidney outcomes have been identified.SummaryMCS is a rapidly evolving field. Kidney health and function before, during, and after MCS is relevant to outcomes from an epidemiologic perspective, yet the pathophysiology underlying this is uncertain. Improved understanding of the relationship between MCS use and kidney health is important to improving patient outcomes.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
