Treatment of porphyria of the skin generally involves the avoidance of sunlight, while treatment for acute porphyria may involve giving intravenous heme or a glucose solution. [2] Rarely, a liver transplant may be carried out. [2] The precise prevalence of porphyria is unclear, but it is estimated to affect between 1 and 100 per 50,000 people. [1]
Erythropoietic protoporphyria (or commonly called EPP) is a form of porphyria, which varies in severity and can be very painful.It arises from a deficiency in the enzyme ferrochelatase, leading to abnormally high levels of protoporphyrin in the red blood cells (erythrocytes), plasma, skin, and liver.

Givosiran, sold under the brand name Givlaari, is a medication used for the treatment of adults with acute hepatic porphyria. [3] [6] [7] [8] Givosiran is a small interfering RNA (siRNA) directed towards delta-aminolevulinate synthase 1 (ALAS1), [9] an important enzyme in the production of heme.
Acute intermittent porphyria (AIP) is a rare metabolic disorder affecting the production of heme resulting from a deficiency of the enzyme porphobilinogen deaminase. It is the most common of the acute porphyrias .
X-linked dominant erythropoietic protoporphyria is a relatively mild version of porphyria with the predominant symptom being extreme photosensitivity causing severe itching and burning sensation of the skin due to the buildup of protoporphyrin IX. One possible treatment was discovered when treating an individual with supplemental iron for a ...
Porphyria cutanea tarda is the most common subtype of porphyria. [1] The disease is named because it is a porphyria that often presents with skin manifestations later in life. The disorder results from low levels of the enzyme responsible for the fifth step in heme production. Heme is a vital molecule for all of the body's organs.
The rate of certified doctors looking to treat up to the maximum 100 patients has slowed. When the federal government began allowing physicians to treat more than 30 patients in 2007, nearly 2,000 doctors applied, according to data from the Substance Abuse and Mental Health Services Administration.
Hereditary coproporphyria (HCP) is a disorder of heme biosynthesis, classified as an acute hepatic porphyria. [1] HCP is caused by a deficiency of the enzyme coproporphyrinogen oxidase, coded for by the CPOX gene, and is inherited in an autosomal dominant fashion, although homozygous individuals have been identified.
