Porphyria

1. Porphyria A Powerpoint Presentation by Jessi Young (Pd 6/7 Day 2)

2. Victim of Porphyria

3. A Brief History • The word “porphyria” derives from the Greek root porphura (πορφύρα) meaning “purple pigment” • There is some speculation as to whether or not this term came from the idea that victims of porphyria would grow bruised and discolored from their disease, and would often take on a violet hue • There is no set date as to when porphyria emerged into mankind. Some of the most prominent cases were found in the late eighteenth to early twentieth centuries • The doctor who first gave an accurate description to porphyria was Dr. B. J. Stokvis • Hippocrates is cited as one of the very first to ever recognize porphyria • Congenital Erythropoietic Porphyria, or CEP, was identified in 1923. To date this is the most prevalent strain of porphyria

5. How it works • Primarily, porphyria affects the nervous system. This can cause abdominal pain, hallucinations, depression, anxiety, and paranoia • Porphyria begins on a cellular level. porphyrins, the main precursors of heme (the main ingredient in hemoglobin etc.) • Porphyria creates dysfunction in porphyrins, which leads to low (and eventually virtually nonexistent) heme production • The build-up of dysfunctional porphyrins in the bloodstream becomes toxic to the tissues in the body, which causes the symptoms of porphyria • Porphyria is largely a blood-related disease, so as a result, in addition to largely affecting the nervous system, the toxic porphyrins have devastating effects on the victim’s liver, usually leading to hepatic encephalopathy(acute liver failure)
