- Certain medications, including hormone drugs.
- Recreational drugs.
- Dieting or fasting.

- Physical stress, such as infections or other illnesses.
- Emotional stress.
- Alcohol use.
Is Ala a porphyrin?
ALAD porphyria is a very rare genetic metabolic disease characterized by almost complete deficiency of the enzyme delta-aminolevulinic acid (ALA) dehydratase. Deficiency of this enzyme leads to the accumulation of the porphyrin precursor ALA, which can potentially result in a variety of symptoms.
Can children have porphyria?
Porphyria symptoms can be present in children, although they emerge more often in early to mid-adulthood after puberty. Over a 23-year period at the University of Barcelona, Spain, only 21 of the 710 cases of porphyria occurred in children.
How long can you live with porphyria?
Patients with porphyria generally have a normal life expectancy. However, those with acute hepatic porphyria are at increased risk of developing high blood pressure, chronic kidney disease, and hepatocellular carcinoma (liver cancer), which may reduce their lifespan.
What causes ALA deficiency?
ALA dehydratase deficiency is a rare cause of hepatic porphyria, meaning that excess porphyrins originate from the liver rather than the bone marrow as in erythropoietic porphyrias….

What is a Porphobilinogen urine test?
Urinary porphobilinogen (PBG) is elevated during the acute phase of the neurologic porphyrias. Urine and fecal porphyrin analysis should be performed to confirm the diagnosis and to distinguish between AIP, HCP and VP.
How is porphyria inherited?
Most of the porphyrias are inherited conditions. The genes for all the enzymes in the heme pathway have been identified. Some forms of porphyria result from inheriting one altered gene from one parent (autosomal dominant). Other forms result from inheriting two altered genes, one from each parent (autosomal recessive).
Why was King George’s pee purple?
In recent years, though, it has become fashionable among historians to put his “madness” down to the physical, genetic blood disorder called porphyria. Its symptoms include aches and pains, as well as blue urine.
What is the survival rate of porphyria?
Results: The 20-year survival was 42.9% (95% confidence interval [CI], 36.9-48.7) for patients with PCT compared with 60.5% (95% CI, 58.6-62.4) for matched control individuals.
