title: A case report of porphyria variegata management in the emergency department.
abstract: BACKGROUND
  Porphyria variegata (VP) is one of the hepatic porphyrias that results from the deficiency of protoporphyrinogen oxidase, an enzyme in the heme synthesis pathway. The name porphyria variegata refers to its many presentations, which include various neuropsychiatric and cutaneous manifestations. Emergency department (ED) presentations due to VP are most commonly neuropathic abdominal pain.
  
  
  METHODS
  We present the case of a 57-year-old woman presenting to an ED with abdominal pain consistent with prior VP attacks. In addition to analgesics and supportive care, infusion of intravenous dextrose resulted in improvement in her symptoms.
  
  
  CONCLUSIONS
  Intravenous dextrose and heme administration remain the first-line treatment for abdominal pain attributable to known acute hepatic porphyria attacks. Recently, the mechanism of action of carbohydrates in treating porphyria has been elucidated. Current information on this illness and ED management are discussed.
