Acute intermittent porphyria should be suspected in individuals presenting with unexplained acute abdominal pain following international air travel. [44]

The relative risk of an acute attack in acute intermittent porphyria compared with that in variegate porphyria was 14 in a series of 112 patients from South Africa with porphyria attack. [45]

A thorough family history for porphyria and the patient's occupational history must be obtained.
