Causes Grouped by strength of evidence
Hexachlorobenzene exposure in adults results in cutaneous photosensitivity and porphyrinuria. However, in infants, exposure results in high mortality and neurotoxicity (convulsions) without porphyrinuria. Aluminum inhibits some heme synthetic enzymes and has been implicated in causing porphyria in chronic hemodialysis patients, whom are often aluminum overloaded. Lead intoxication causes signs and symptoms similar to acute intermittent porphyria including abdominal pain, constipation and vomiting. However, anemia which is often found with lead intoxication is virtually absent in porphyria.
