Gallstones, mild liver dysfunction[12] 1 in 75,[17]—,[17] Pathogenesis Heme synthesis—note that some reactions occur in the cytoplasm and some in the mitochondrion yellow In humansporphyrins are the main precursors of hemean essential constituent of hemoglobinmyoglobincatalaseperoxidaseand P liver cytochromes.

The body requires porphyrins to produce hemewhich is used to carry oxygen in the blood among other things, but in the porphyrias there is a deficiency inherited or acquired of the enzymes that transform the various porphyrins into others, leading to abnormally high levels of one or more of these substances.

Porphyrias are classified in two ways, by symptoms and by pathophysiology. Physiologically, porphyrias are classified as liver or erythropoietic based on the sites of accumulation of heme precursors, either in the liver or in the bone marrow and red blood cells.

Heme function plays a central role in cellular metabolism. This is not the main problem in the porphyrias; most heme synthesis enzymes —even dysfunctional enzymes —have enough residual activity to assist in heme biosynthesis. The principal problem in these deficiencies is the accumulation of porphyrinsthe heme precursors, which are toxic to tissue in high concentrations.

The chemical properties of these intermediates determine the location of accumulation, whether they induce photosensitivityand whether the intermediate is excreted in the urine or feces.

There are eight enzymes in the heme biosynthetic pathway, four of which—the first one and the last three—are in the mitochondriawhile the other four are in the cytosol.

Defects in any of these can lead to some form of porphyria. The hepatic porphyrias are characterized by acute neurological attacks seizurespsychosisextreme back and abdominal painand an acute polyneuropathywhile the erythropoietic forms present with skin problems, usually a light-sensitive blistering rash and increased hair growth.

Variegate porphyria also porphyria variegata or mixed porphyriawhich results from a partial deficiency in PROTO oxidasemanifests itself with skin lesions similar to those of porphyria cutanea tarda combined with acute neurologic attacks. All other porphyrias are either skin- or nerve-predominant.

Diagnosis Porphyrin studies Porphyria is diagnosed through biochemical analysis of bloodurineand stool. As a result of feedback, the decreased production of heme leads to increased production of precursors, PBG being one of the first substances in the porphyrin synthesis pathway.

The urine screening test has been known to fail in the initial stages of a severe, life-threatening attack of acute intermittent porphyria. The exception to this may be latent post-puberty genetic carriers of hereditary coproporphyria.

As most porphyrias are rare conditionsgeneral hospital labs typically do not have the expertise, technology, or staff time to perform porphyria testing. In general, testing involves sending samples of blood, stool, and urine to a reference laboratory. Samples should be taken during an acute attack; otherwise a false negative result may occur.

Samples must be protected from light and either refrigerated or preserved. A careful medication review often will find the cause of pseudoporphyria. Additional tests Further diagnostic tests of affected organs may be required, such as nerve conduction studies for neuropathy or an ultrasound of the liver.In the chapter "Robert Browning's Sacred and Legendary Art," LaPorte characterizes The Ring and Book as "demonstrat[ing] Browning's engagement with hermeneutics on its largest scale" (p.
