A rare cause of postpartum coma: isolated hyperammonemia due to urea cycle disorder

      We read the correspondence with great interest. Our aim to report this case was to discuss different etiologies causing altered mental status of patients in postpartum period and to suggest ammonia level detection in routine. The symptoms of our case had started on the fifth postpartum day, urinary infection was excluded by negative urine culture and being in the postpartum period was the strongest clue for excessive catabolic process to suspect urea cycle disorder. Hemodialysis was performed and sodium benzoate was started in our patient. Klebsiella related urinary infection was not discussed because of excluding infectious etiologies in our patient.
