Sodium-glucose cotransporter 2 (SGLT-2) inhibitors are a class of medications used for glycemic control in type II diabetes mellitus. Their mechanism of action involves preventing resorption of glucose at the proximal kidney, thereby promoting glucosuria and weight loss. However, they have also been found to be associated with euglycemic diabetic ketoacidosis (euDKA). This case describes a 25-year-old male with a history of type II diabetes on metformin, sitagliptin, and dapagliflozin who was admitted with his third episode of pancreatitis secondary to hypertriglyceridemia. His home oral glycemic agents were continued as inpatient. Despite tight euglycemic control, the patient developed profound metabolic acidosis and was found to have an elevated beta-hydroxybutyrate level and normal lactic acid level. He was admitted into the intensive care unit and started on an insulin drip, and after resolution of his acidosis he was transitioned to basal insulin successfully. He was discharged with an insulin regimen while his oral glycemic agents were discontinued indefinitely. SGLT-2 inhibitors are associated with euDKA, most likely as a result of their non-insulin-dependent glucose clearance, hyperglucagonemia, and decreased ketone clearance. The aim of this case report is to inform the physician about the possibility of euDKA in a patient with type II diabetes on a SGLT-2 inhibitor presenting with an acute illness.
钠-葡萄糖协同转运蛋白2(SGLT-2)抑制剂是一类用于控制2型糖尿病血糖的药物。其作用机制包括阻止近端肾单位对葡萄糖的重吸收,从而促进糖尿和体重减轻。然而,人们也发现它们与正常血糖性糖尿病酮症酸中毒(euDKA)有关。本病例描述了一名25岁男性,有2型糖尿病病史,正在服用二甲双胍、西他列汀和达格列净,因高甘油三酯血症继发胰腺炎第三次发作入院。住院期间继续使用其在家时的口服降糖药。尽管血糖控制严格,但患者出现了严重的代谢性酸中毒,且发现β-羟基丁酸水平升高而乳酸水平正常。他被收入重症监护病房并开始静脉滴注胰岛素,酸中毒纠正后成功过渡到基础胰岛素治疗。出院时采用胰岛素治疗方案,同时无限期停用口服降糖药。SGLT-2抑制剂与euDKA有关,很可能是由于其非胰岛素依赖的葡萄糖清除、高胰高血糖素血症和酮清除减少。本病例报告的目的是告知医生,在患有2型糖尿病且正在使用SGLT-2抑制剂的患者出现急性疾病时发生euDKA的可能性。
