Management of diabetes‐related hyperglycaemic emergencies in advanced chronic kidney disease: Review of the literature and recommendations

Abstract Aims Despite the substantial progress in the management of diabetes mellitus (DM), chronic kidney disease (CKD) remains one of the most common complications. Although uncommon, diabetic emergencies [diabetic ketoacidosis (DKA), hyperosmolar hyperglycaemic state (HHS)] can still occur in stage 4 and 5 CKD, at times with less typical clinical manifestations due to the altered pathophysiology, presence of chronic metabolic acidosis and effect of haemodialysis on glycaemic control and metabolic parameters. The purpose of this article is to review the current literature and provide recommendations for the diagnosis and treatment of DKA, euglycaemic DKA and HHS in people with advanced CKD. Methods and Results Guidance on the management of diabetes‐related emergencies mainly focuses on individuals with preserved renal function or early‐stage CKD. Existing literature is limited, and recommendations are based on expert opinions and case reports. Given the clinical need for amended guidelines for this population, we are proposing a management algorithm for DKA and HHS based on clinical and metabolic parameters. Conclusions In this review article, we propose treatment algorithms for diabetes‐related hyperglycaemic emergencies in people with advanced CKD. Further research is needed to validate our proposed algorithms.
