Question 1
A 58-year-old male with a 7-year history of type 2 diabetes mellitus (T2DM), established coronary artery disease (post-CABG 3 years ago), and stage G3a diabetic kidney disease (eGFR 52 mL/min/1.73m², urine albumin-to-creatinine ratio [RAC] 180 mg/g) presents for routine follow-up. His current medications include metformin 1,000 mg twice daily, atorvastatin 40 mg, enalapril 20 mg daily, and carvedilol 25 mg twice daily. His HbA1c is 7.4% and blood pressure is 128/78 mmHg. According to the Sociedade Brasileira de Diabetes (SBD) and ADA/EASD consensus guidelines, what is the most appropriate next step in his glycemic and cardiorenal management?
Correct Answer:
Add an SGLT2 inhibitor (e.g., empagliflozin or dapagliflozin) or a GLP-1 receptor agonist with proven cardiorenal benefit, independent of baseline HbA1c.
Question 2
A 22-year-old female with type 1 diabetes mellitus (T1DM) is admitted to the emergency department with severe diabetic ketoacidosis (cetoacidose diabética - CAD). Initial labs revealed blood glucose 480 mg/dL, arterial pH 7.12, serum bicarbonate 10 mEq/L, and anion gap 24 mEq/L. She is treated with intravenous normal saline, potassium replacement, and continuous regular insulin infusion. After 14 hours of infusion, her capillary glucose is 180 mg/dL, venous pH is 7.34, serum bicarbonate is 19 mEq/L, and calculated anion gap is 10 mEq/L. She is alert, nausea has resolved, and she requests lunch. According to SBEM and SBD protocols, what is the most appropriate management at this stage?
Correct Answer:
Administer subcutaneous basal insulin along with prandial rapid-acting insulin 1 to 2 hours before stopping the intravenous insulin infusion.
Question 3
A 74-year-old male is brought to the emergency department with profound lethargy, severe dehydration, and obtundation. Laboratory evaluation reveals: plasma glucose 940 mg/dL, serum sodium 152 mEq/L, potassium 4.8 mEq/L, bicarbonate 20 mEq/L, arterial pH 7.36, serum creatinine 2.4 mg/dL (baseline 1.0 mg/dL), and calculated effective serum osmolality 342 mOsm/kg. Urine dipstick shows trace ketones. A diagnosis of Hyperosmolar Hyperglycemic State (Estado Hiperosmolar Hiperglicêmico - EHH) is established. What is the initial priority in the resuscitation of this patient?
Correct Answer:
Aggressive fluid resuscitation with isotonic 0.9% NaCl (1,000–1,500 mL in the first hour) to restore intravascular volume, followed by reassessment of corrected sodium.
Question 4
A 16-year-old adolescent with newly diagnosed type 1 diabetes mellitus (T1DM) was discharged on a total daily insulin dose of 0.6 units/kg/day. Three months later, his mother reports frequent mild hypoglycemic episodes. Over the past 4 weeks, his required total daily insulin dose has dropped to 0.18 units/kg/day while maintaining fasting glucose between 80–115 mg/dL and postprandial glucose < 140 mg/dL. His HbA1c is 5.8%. Diagnostic autoantibody panel was positive for anti-GAD65 and anti-ZnT8. What clinical phenomenon best explains his current status?
Correct Answer:
The 'honeymoon period' (fase de lua de mel), characterized by transient endogenous beta-cell recovery following the correction of initial glucotoxicity.
Question 5
A 52-year-old woman with type 2 diabetes treated with dapagliflozin 10 mg and metformin 1,000 mg twice daily undergoes elective laparoscopic cholecystectomy. Forty-eight hours postoperatively, she develops tachypnea, nausea, vomiting, and diffuse abdominal pain. Capillary blood glucose is 158 mg/dL. Arterial blood gas demonstrates pH 7.18, pCO2 22 mmHg, HCO3 8 mEq/L, and serum anion gap of 22 mEq/L. Blood beta-hydroxybutyrate is elevated at 4.8 mmol/L. What is the diagnosis and what is the key preventive measure recommended by SBEM/SBD regarding SGLT2 inhibitors?
Correct Answer:
Euglycemic Diabetic Ketoacidosis (CAD euglicêmica); SGLT2 inhibitors must be withheld at least 3 to 4 days prior to elective major surgery.
