It is caused by abnormalities in the gene coding for uridine diphosphogluconurate glucuronosyltransferase UGT1A1. However, without porphobilinogen deaminasea necessary cytoplasmic enefrmedad, heme synthesis cannot finish, and the metabolite porphobilinogen accumulates in the cytoplasm. Barbiturates and Primidone must be avoided as they commonly precipitate symptoms. Signs and symptoms of AIP can be variable.

Psychiatric signs and symptoms of AIP may manifest as anxietyagitationhallucinationsdeliriumor depression. X-linked sideroblastic anemias and the porphyrias. Acute intermittent rnfermedad AIP is a rare autosomal dominant [1] metabolic disorder affecting the production of hemethe oxygen-binding prosthetic group of hemoglobin.

Other search option s Alphabetical list. Hot water baths or showers may lessen nausea temporarily, but can present a risk of burns or falls. Most patients type IA have a mutation in one of the common exons 2 to 5and have difficulties conjugating several additional substrates several drugs and xenobiotics. Crigler—Najjar syndrome or CNS is a rare inherited disorder affecting the dd of bilirubina chemical formed from the breakdown of the heme in red blood cells. A smaller percentage of patients type IB have mutations limited to the bilirubin-specific A1 exon; their conjugation defect is mostly restricted to bilirubin itself.


Side-effects are rare but can be serious.

Acute intermittent porphyria

No UDP glucuronosyltransferase 1-A1 expression can be detected in the liver tissue. One of the many hypothesized diagnoses of the artist Vincent van Gogh is that he and his siblings, in particular his brother Theosuffered from AIP and syphilis.

Hence, there is no response to treatment with phenobarbital[1] which causes CYP enzyme induction.

UGT1A1 normally catalyzes the conjugation of bilirubin and glucuronic acid within hepatocytes. Pain is extremely severe and enfermead always requires the use of opiates to reduce it to tolerable levels. In the United Kingdom, supplies of this drug are maintained at two national centers.


Crigler–Najjar syndrome

Subsequent treatment with anti-psychotics increases the accumulation of porphobilinogen, thus aggravating the disease enough that it may prove fatal. Urinary symptoms such as painful urinationurinary retentionurinary incontinenceor dark urine enfdrmedad also been known to occur. One year-old girl with Crigler—Najjar syndrome type I was successfully treated by liver cell transplantation.

Unlike Gilbert’s syndrome, only a few causes of CNS are known.

Dubin—Johnson syndrome Rotor syndrome. Seizures often accompany this disease. One possible complication of low blood sodium in those with AIP is seizures. Prematurity results in higher levels. European Journal of Pediatrics. Summary An Orphanet summary for this disease is currently under development.

Inheritance is autosomal recessive. Please help improve this article by adding citations to reliable sources. Since only one enzyme is working improperly, gene therapy for Crigler-Najjar is a theoretical option which is being investigated.
