A 52-year-old man is brought to the emergency department after being found confused in his garage. He has nausea and flank pain. Laboratory studies show high anion gap metabolic acidosis, elevated osmolar gap, hypocalcemia, and numerous envelope-shaped crystals in the urine. Which of the following is the most likely cause of this patient's findings?

  1. A)Aspirin overdose
  2. B)Diarrhea
  3. C)Methanol ingestion
  4. D)Distal renal tubular acidosis
  5. E)Ethylene glycol ingestionGABARITO

Explicação

Ethylene glycol is metabolized to glycolic and oxalic acids, causing a high anion gap metabolic acidosis. Oxalate binds calcium and can precipitate as calcium oxalate crystals in the urine, making hypocalcemia and envelope-shaped crystals highly characteristic...
