    Extractions: Mechanism of porphyrin-induced photosensitivity: The photosensitivity of the skin in porphyria is due to porphyrins absorbing ultraviolet radiation in the 400 nm range and emitting an intense red fluorescence. Porphyrins, when irradiated with light of the appropriate wavelength in the presence of oxygen, will cause photodynamic effects. Light energy absorbed by the porphyrin raises electrons into an excited state. Energy released on return of the molecule to its original state reacts with oxygen to produce free radicals and singlet oxygen (O) which damages molecules, cells and tissues. Unsaturated lipids are particular targets for activated oxygen species; cell damage results from the resulting plasma membrane and lysosomal membrane injury and also from complement activation.

    Extractions: Deficiency in the enzymes of the porphyrin pathway leads to insufficient production of heme. This is, however, not the main problem; most enzymes - even when less functional - have enough residual activity to assist in heme biosynthesis. The largest problem in these deficiencies is the accumulation of porphyrins, the heme precursors, which are toxic to tissue in high concentrations. The chemical properties of these intermediates determine in which tissue they accumulate, whether they are photosensitive , and how the compound is excreted (in the urine or feces There are eight enzymes in the heme biosynthetic pathway: the first and the last three are in the mitochondria , while the other four are in the cytosol δ-aminolevulinate (ALA) synthase δ-aminolevulinate (ALA) dehydratase hydroxymethylbilane (HMB) synthase uroporphyrinogen (URO) synthase uroporphyrinogen (URO) decarboxylase coproporphyrinogen (COPRO) oxidase protoporphyrinogen (PROTO) oxidase ferrochelastase The hepatic porphyrias include: ALA dehydratase deficiency acute intermittent porphyria (AIP): a deficiency in HMB synthase hereditary coproporphyria (HCP): a deficiency in COPRO oxidase variegate porphyria (VP): a deficiency in PROTO oxidase porphyria cutanea tarda (PCT): a deficiency in URO decarboxylase

    Extractions: Wed Jun 17 14:26:55 1998 well - the literature yields its usual mixed bag of results. apparently we need to know more about which of the porphyrias you are dealing with. oral contraceptives either precipitate or prevent certain porphyrias. additionally, there is one case report of a woman's developing porphyria on withdrawal of oc's. go figure. see below: J Am Acad Dermatol 1994 Aug;31(2 Pt 2):390-392 Porphyria cutanea tarda: pregnancy versus estrogen effect. Urbanek RW, Cohen DJ Department of Medicine, Staten Island University Hospital, NY 10305. We describe the worsening of porphyria cutanea tarda in a young woman while she was taking oral contraceptives. However, she did not have an exacerbation during two pregnancies. We conclude that estrogens produced during pregnancy do not exert the same effect as orally administered medications that contain estrogen. The pronounced effect of oral ethinyl estradiol on the liver may be attributed to its first-pass effect on that organ. Horm Metab Res 1995 Aug;27(8):379-383

    Extractions: In the acute porphyrias ; acute intermittent porphyria , urophorphyrinogen 1 synthase, hereditary coproporphyria, coproporphyrinogen oxidase and variegate porphyria , ferrochelatase or protoporphyrinogen oxidase , are the enzymes affected, whilst in the non acute porphyrias , cutaneous hepatic porphyria , uroporphyrinogen decarboxylase, congenital porphyria , uroporphyrinogen cosynthase; and erythropoietic protoporphyria; ferrochelatase are the enzymes affected. As a consequence of this secondary control, there is excessive excretion of the porphyrin precursors delta-aminolaevulinic acid and porphobilinogen in the acute porphyrias and excessive excretion of porphyrins leading to solar photosensitivity in the non-acute porphyrias and in variegate and hereditary coproporphyria.

    Extractions: In one study involving two brothers (2 and 10 years old) with erythropoietic protoporphyria, treatment with the drug S-adenosyl-L-methionine produced significant improvement in clinical and biochemical parameters, said Dr. A-M Pierini, department of pediatric dermatology, Hospital de Pediatria "J. P. Garrahan" and Center for Investigation of Porphyrias and Porphyrins, Buenos Aires, Argentina. When the two brothers were treated with one to three courses - 12 to 15 mg/kg/day for 20 days - of S-adenosyl-L-methionine, clinical improvement was noticeable at the end of one course. Blood levels of protoporphyrin returned to normal (150 ng/ml red blood cells) from their respective pretreatment levels of 199 and 291 ng/100 ml red blood cells. The porphyrin plasma index followed a
