Owing to a defect in one of the enzymes of the heme biosynthesis pathway, protoporphyrins or porphyrins (heme precursors) are prevented from proceeding further along the pathway.

Are there real vampires living among us?

It is said vampires exist but some say it is all false, they is a disease called vampire disease, the proper name for it is Porphyrias. Porphyrias are a group of inherited or acquired disorders of certain enzymes in the heme bio-synthetic pathway (also called porphyrin pathway). They are broadly classified as acute (hepatic) porphyrias and cutaneous (erythropoietic) porphyrias, based on the site of the overproduction and accumulation of the porphyrins (or their chemical precursors). They manifest with either neurological complications or skin problems (or occasionally both). A clinically induced and histologically identical condition is called pseudoporphyria. Pseudoporphyria is characterized by normal serum and urine porphyrin levels.


What are alternative treatments for porphyrias?

Acupuncture or hypnosis and relaxation techniques such as yoga may be used as adjuncts to conventional therapy. As acute attacks can be life threatening it is important to have a physician.
