Summary
We describe two cases of SGLT2i-induced euglycaemic diabetic ketoacidosis, which took longer than we anticipated to treat despite initiation of our DKA protocol. Both patients had an unequivocal diagnosis of type 2 diabetes, had poor glycaemic control with a history of metformin intolerance and presented with relatively vague symptoms post-operatively. Neither patient had stopped their SGLT2i pre-operatively, but ought to have by current treatment guidelines.
Learning points:
-
SGLT2i-induced EDKA is a more protracted and prolonged metabolic derangement and takes approximately twice as long to treat as hyperglycaemic ketoacidosis.
-
Surgical patients ought to stop SGLT2i medications routinely pre-operatively and only resume them after they have made a full recovery from the operation.
-
While the mechanistic basis for EDKA remains unclear, our observation of marked ketonuria in both patients suggests that impaired ketone excretion may not be the predominant metabolic lesion in every case.
-
Measurement of insulin, C-Peptide, blood and urine ketones as well as glucagon and renal function at the time of initial presentation with EDKA may help to establish why this problem occurs in specific patients.

Summary
Diabetic nephropathy, a microvascular complication of diabetes, is a progressive kidney disease caused by angiopathy of the capillaries in the kidney glomeruli. Herein, we report a case of a 62-year-old patient with a 30 year history of diabetes, who showed a substantial improvement in diabetic nephropathy on administration of 30 g of Astragalus membranaceus extract per day. After 1 month, estimated glomerular filtration rate increased from 47 to 72 ml/min per 1.73 m2 and was subsequently maintained at the 1-month follow-up. Urinary protein levels also decreased following treatment. Herein, we present and discuss the evidence and mechanism of A. membranaceus on diabetic nephropathy in this patient.
Learning points
-
Diabetic nephropathy is a progressive kidney disease.
-
Angiotensin-converting enzyme (ACE) inhibitors or angiotensin receptor blockers (ARBs) are currently used to prevent and delay the progression of diabetic nephropathy. However, their effects are not sufficient to prevent a decline in kidney function.
-
Furthermore, combination therapy with an ACE inhibitor and an ARB can produce adverse effects without additional benefits.
-
In the early phase of diabetic nephropathy, administration of Astragalus membranaceus can be a therapeutic option.
