Ketoacidosis with euglycemia in a patient with type 2 diabetes mellitus taking dapagliflozin: A case report

Safety assessment of dapagliflozin: Real-world adverse event analysis based on the FAERS database from 2012 to 2023

Background

Dapagliflozin possesses the capacity to cure a wide range of diseases, however, there are many adverse events (AEs) that have not yet been acknowledged or recorded.

Aim

Safety assessment of dapagliflozin based on the Food and Drug Administration Adverse Event Reporting System (FAERS) database, to explore differences between the reported AEs to provide a overview of the safety profile of dapagliflozin.

Methods

We extracted data from the United States FAERS database, including from the fourth quarter of 2012 to the third quarter of 2023. Reporting odds ratio (ROR), proportional reporting ratio (PRR), Bayesian confidence propagation neural network (BCPNN), and empirical Bayesian geometric average (EBGM) were used to evaluate the relationship between dapagliflozin and its associated AEs.

Results

A total of 13,593,946 case reports were gathered from the Food and Drug Administration Adverse Event Reporting System database for this investigation. Among these, there were 44,506 episodes of adverse events that were associated with dapagliflozin. Included in the analysis were 341 preferred words and 2 system organ classes that showed statistical significance according to all four methods simultaneously. The system organ classes encompassed illnesses related to metabolism and nutrition, as well as problems affecting the renal and urinary systems. PT levels were screened for adverse drug reaction signals including scrotal gangrene, scrotal cellulitis, perineal cellulitis, diabetic ketoacidosis, and pancreatitis.

Conclusion

The majority of our findings aligned with the specification, however, certain novel indicators of AEs such as acute pancreatitis were not accounted for. The analysis of the AE signals may provide support for clinical monitoring and risk identification of dapagliflozin. Due to the inherent limitations of FAERS data, well-designed studies are required to demonstrate the safety of dapagliflozin.

Clinical and biochemical characteristics and analysis of risk factors for euglycaemic diabetic ketoacidosis in type 2 diabetic individuals treated with SGLT2 inhibitors: A review of 72 cases over a 4.5-year period

BACKGROUND AND AIMS

To study euglycemic diabetic ketoacidosis (euDKA) outcomes associated with sodium-glucose co-transporter 2 inhibitors (SGLT2is) METHODS: Review of 72 euDKA cases in T2DM between September 2015 and January 2020 (PUBMED).

RESULTS

euDKA could occur at any time during SGLT2is treatment, with nausea, abdominal pain and vomiting as main symptoms. Hyperglycemia did not correlate with pH and β-hydroxybutyrates. Low pH and high β-hydroxybutyrates were significantly associated with euDKA. In biguanides users, acidosis was unrelated to lactic acidosis. euDKA occurred during fasting, surgery, acute infection, insulin deprivation (endogenous or exogenous).

CONCLUSIONS

These data support avoidance of euDKA risk states in SGLT2i users.

SGLT-2 inhibitors associated euglycemic and hyperglycemic DKA in a multicentric cohort

Euglycemic diabetic ketoacidosis (EuDKA) secondary to Sodium-glucose co-transporter-2 inhibitors (SGLT2i) in type 2 diabetes mellitus (T2D) is a rare but increasingly reported phenomenon. Not much is known about the burden of EuDKA in patients on SGLT2i or the associated factors. This retrospective cohort study tries to delineate the differences in factors associated with the development of EuDKA as compared to hyperglycemic DKA. We conducted a multicentre, retrospective study across three tertiary care centers under Weill Cornell affiliated-Hamad Medical Corporation, Qatar. The cohort comprised of T2D patients on SGLT2i who developed DKA between January 2015 to December 2020. The differences between the subjects who developed EuDKA or hyperglycaemic DKA (hDKA) were analyzed. A total of 9940 T2D patients were on SGLT2i during 2015-2020, out of which 43 developed DKA (0.43%). 25 developed EuKDA, whereas 18 had hDKA. The point prevalence of EuDKA in our cohort was 58.1%. EuDKA was most common in patients using canagliflozin, followed by empagliflozin and Dapagliflozin (100%, 77%, and 48.3%, respectively). Overall, infection (32.6%) was the most common trigger for DKA, followed by insulin non-compliance (13.7%). Infection was the only risk factor with a significant point estimate between the two groups, being more common in hDKA patients (p-value 0.006, RR 2.53, 95% CI 1.07-5.98). Canagliflozin had the strongest association with the development of EuDKA and was associated with the highest medical intensive care unit (MICU) admission rates (66.6%). In T2D patients on SGLT2i, infection is probably associated with an increased risk of developing EuDKA. The differential role of individual SGLT2i analogs is less clear and will need exploration by more extensive prospective studies.

EUGLYCEMIC DIABETIC KETOACIDOSIS (EDKA) IN A PATIENT RECEIVING DAPAGLIFLOZIN

SGLT-2 inhibitors have gained importance in recent years because of their cardio-protective and reno-protective properties in diabetes. SGLT-2 inhibitors, when introduced in diabetic patients, may cause euglycemic diabetic ketoacidosis. A 55-year-old woman presented with low-grade fever, vomiting, and lethargy. She was started on dapagliflozin two years back. On workup, she was diagnosed with euglycemic diabetic ketoacidosis (EDKA) and was managed accordingly. She improved clinically while her dapagliflozin was stopped. With a literature search, we have identified 15 case reports of EDKA with dapagliflozin since 2015. There are no standard guidelines regarding the monitoring of patients for this rare but potentially morbid complication. Moreover, the exact mechanism for this is unknown. Various precipitating factors are linked with SGLT-2 inhibitors in promoting EDKA. We recommend that customary plans should comprise educating the patient about this rare complication before commencing medication, close follow-up with serial electrolyte monitoring, and discontinuing medications in the state of infection, dehydration and recent surgery and serious illness requiring hospitalization.

Euglycemic diabetic ketoacidosis caused by canagliflozin: a case report

Background

Diabetic ketoacidosis (DKA) is seen relatively frequently in the emergency department (ED). DKA is characterized by hyperglycemia, acidosis, and ketonemia, and sodium glucose transporter 2 inhibitors (SGLT2i) represent a new diabetes medication that has been associated with euglycemic DKA (eu-DKA).

Case presentation

A 71-year-old female who was being treated for type 2 diabetes with canagliflozin, metformin, and saxagliptin orally presented to the ED for evaluation of reduced oral intake, malaise, nausea, and abdominal pain. Although her blood glucose was not severely elevated (259 mg/dL), there was notable ketoacidosis (pH 6.89; CO₂, 11.4 mmHg; HCO₃, 1.9 mEq/L; base excess, − 31.3 mmol/L; 3-hydroxybutyric acid > 10,000 μmol/L) was observed. The uncontrolled acidosis improved following 3 days of continuous renal replacement therapy, but elevated urinary glucose continued for more than 10 days. Ringer’s lactated fluid supplementation was continued for management of polyurea and glucosuria. Urinary glucose turned negative on day 16, and there was improvement in the patient’s overall state; hence, she was discharged on day 18.

Conclusion

Although it is difficult to diagnose eu-DKA because of the absence of substantial blood glucose abnormalities in the ED, there is a need to consider eu-DKA when evaluating acidosis in a patient treated with SGLT2i. Moreover, even after discontinuing the SGLT2i, attention should be given to the possibility of continuing glucosuria. Regular measurements of urinary glucose should be obtained, and the patient should be monitored for dehydration.
