Abstract
Variegate porphyria is a genetic disorder of porphyrin metabolism in which patients may have both neurologic dysfunction and photocutaneous lesions. Biochemical confirmation of the diagnosis can be difficult, particularly in patients without neurologic dysfunction at the time of testing. The demonstration of increased fecal excretion of porphyrin is frequently used for this purpose, but levels may be normal. Since elevated fecal porphyrin levels in variegate porphyria are presumably a consequence of increased biliary excretion, we evaluated whether analysis of porphyrins in bile distinguishes better between patients with variegate porphyria and controls.
