SLC5A2 and lactic acidosis: Markedly elevated anion gap (41.9 mEq/L) in the context of severe acidosis (pH 6.77), high lactate (9.7 mmol/L), and elevated β-hydroxybutyrate (106 mg/dL) confirmed a mixed high anion gap metabolic acidosis, secondary to both metformin-associated lactic acidosis and SGLT2 inhibitors-induced euglycemic ketoacidosis.
