AIP is one of the four porphyrias that presents as an acute attack. Heme is produced in all cells, but 80% of all heme is produced in erythropoietic cells in bone marrow and 15% in parenchymal cells in the liver, where turnover of hemoproteins is high. For most diseases, symptoms will vary from person to person. [8] Attacks are most common in young adult women and are rare before puberty or after menopause.

A positive test should be indicated with an increase of five times normal, not just a slight increase which can occur with dehydration. Porphyria is a group of diseases that entails defects in metabolism of heme resulting in too much secretion of porphyrin precursors and pophyrins. The acute porphyrias (acute intermittent porphyria, variegate porphyria, hereditary coproporphyria, and 5-aminolaevulinic acid dehydratase deficiency porphyria) are hereditary disorders of haem biosynthesis; they have a prevalence of about 1 in 75 000 of the population.

Now, heme synthesis is also called porphyrin synthesis and when halted, it result in the buildup of one of its precursors molecules. Acute intermittent porphyria (AIP) is a rare metabolic disorder affecting the production of heme resulting from a deficiency of the porphobilinogen deaminase. However, the majority of people with a mutation in this gene do not develop symptoms of AIP; additional factors, often called “triggers” are also required to cause symptomatic acute Porphyria.

One of the many hypothesized diagnoses of the artist Vincent van Gogh is that he and his siblings, in particular his brother Theo, suffered from AIP and syphilis. Treatment can be problematic: Barbiturates and primidone must be avoided as they commonly precipitate symptoms. [20], Porphyrias are caused by mutations in genes that encode enzymes in heme synthesis. In any chronic illness, it's integral to find like-minded communities and the APF is … [] AIP manifests as episodes of abdominal pain, neuropathies, and constipation, but, unlike most types of porphyria, patients with AIP do not have a rash.
