SUCCESSFUL REIMPLEMENTATION OF A VERY LOW CARBOHYDRATE KETOGENIC DIET AFTER SGLT2 INHIBITOR ASSOCIATED EUGLYCEMIC DIABETIC KETOACIDOSIS

The Ketogenic Effect of SGLT-2 Inhibitors-Beneficial or Harmful?

Sodium-glucose cotransporter-2 (SGLT-2) inhibitors, also called gliflozins or flozins, are a class of drugs that have been increasingly used in the management of type 2 diabetes mellitus (T2DM) due to their glucose-lowering, cardiovascular (CV), and renal positive effects. However, recent studies suggest that SGLT-2 inhibitors might also have a ketogenic effect, increasing ketone body production. While this can be beneficial for some patients, it may also result in several potential unfavorable effects, such as decreased bone mineral density, infections, and ketoacidosis, among others. Due to the intricate and multifaceted impact caused by SGLT-2 inhibitors, this initially anti-diabetic class of medications has been effectively used to treat both patients with chronic kidney disease (CKD) and those with heart failure (HF). Additionally, their therapeutic potential appears to extend beyond the currently investigated conditions. The objective of this review article is to present a thorough summary of the latest research on the mechanism of action of SGLT-2 inhibitors, their ketogenesis, and their potential synergy with the ketogenic diet for managing diabetes. The article particularly discusses the benefits and risks of combining SGLT-2 inhibitors with the ketogenic diet and their clinical applications and compares them with other anti-diabetic agents in terms of ketogenic effects. It also explores future directions regarding the ketogenic effects of SGLT-2 inhibitors.

Sodium-Glucose Co-transporter 2 Inhibitor-Associated Euglycemic Diabetic Ketoacidosis After Bariatric Surgery: A Case and Literature Review

Sodium-glucose cotransporter-2 inhibitors (SGLT2i) reduce cardiovascular, kidney, and overall mortality. SGLT2i are also associated with a rare adverse event, euglycemic diabetic ketoacidosis (EDKA). This report describes a case of EDKA one day after bariatric surgery in a 51-year-old female with type 2 diabetes mellitus managed with the SGLT2i, canagliflozin. She was following a ketogenic diet for three weeks prior to surgery. The patient made a steady recovery with rapid anion gap closure followed by prolonged non-anion gap metabolic acidosis. Her medical record was tagged with a life-threatening reaction to SGLT2i. The risk of EDKA from SGLT2i may be increased by a low carbohydrate diet or postoperative status. Our case was complicated by hypokalemia, exemplifying the need for aggressive electrolyte management. Further guidance is needed to manage risk factors provoking EDKA and the use of SGLT2i therapy after an episode of EDKA.

Euglycemic Diabetic Ketoacidosis and Sodium-Glucose Cotransporter-2 Inhibitors: A Focused Review of Pathophysiology, Risk Factors, and Triggers

Diabetic ketoacidosis (DKA) is an acute and significant life-threatening complication of diabetes. The association of sodium-glucose cotransporter-2 inhibitors (SGLT2i) with euglycemic diabetic ketoacidosis (EDKA) has been well reported. This literature review was conducted to understand the mechanism of EDKA and identify the potential risk factors and precipitants for patients taking SGLT2i. After reviewing the published literature between 2010 and 2020, 32 articles are included in the final review. The underlying mechanism is mainly enhanced lipolysis and ketone body reabsorption. SGLT2i also stimulates pancreatic alpha cells and inhibits beta cells, causing an imbalance in glucagon/insulin levels, further contributing to lipolysis and ketogenesis. Most patients were diagnosed with blood glucose less than 200 mg/dL, blood pH <7.3, increased anion gap, increased blood, or urine ketones. Perioperative fasting, pancreatic etiology, low carbohydrate or ketogenic diet, obesity, and malignancy are identified precipitants in this review. As normoglycemia can conceal the underlying acidosis, physicians should be cognizant of the EDKA diagnosis and initiate prompt treatment. Patient education on risk factors and triggers is recommended to avoid future events.
