Views Read Edit View history. European Journal of Pediatrics. Patients that experience frequent attacks can develop chronic neuropathic pain in extremities as well as chronic pain in the gut.

Crigler—Najjar syndrome or CNS is a rare inherited disorder affecting the metabolism of bilirubina chemical formed from the breakdown of the heme in red blood cells. These drugs need to be given very early in an attack to be effective.

Specialised Social Services Eurordis directory. Hence, there is no response to treatment with phenobarbital[1] which causes CYP enzyme induction. Hereditary coproporphyria Harderoporphyria Variegate porphyria Erythropoietic protoporphyria. Gilbert’s syndrome Crigler—Najjar syndrome Driscol syndrome. Articles with short description Articles needing additional references from January All articles needing additional references Infobox medical condition new.

Other neurologic drkscoll and symptoms of AIP include peripheral neuropathy and abnormal sensations. A smaller percentage of patients type IB have mutations limited to the bilirubin-specific A1 exon; their conjugation defect is mostly restricted to bilirubin enffrmedad. Prematurity results in higher levels.

Effectiveness enfeermedad among individuals. 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. Summary An Orphanet summary for this drisclll is currently under development. This is thought to be due to axonal nerve deterioration in affected areas of the nervous system.


No evidence for hemolysis is seen. Before the availability of phototherapythese children died of kernicterus bilirubin encephalopathy or survived until early adulthood with clear neurological impairment. Nausea can be severe; it may respond to phenothiazine drugs but is sometimes intractable. It is characterized by a deficiency of the enzyme porphobilinogen deaminase.

Crigler–Najjar syndrome – Wikipedia

Although results for this trial are still undergoing rigorous testing. Seizures often accompany this disease. These two types, along with Gilbert’s syndromeDubin—Johnson syndromeand Rotor syndromemake up the five known hereditary defects in bilirubin metabolism.

In this condition, there is no release of red urine and no red discoloration in the patient’s skin due to the lack of porphyrin ring synthesis all together during acute attacks.

Since only one enzyme is working improperly, gene therapy for Crigler-Najjar is a theoretical option which is enfrrmedad investigated.

Inheritance is autosomal recessive. Mutations include deletions, inversions, and translations. Please help improve this article by adding citations to reliable sources.

Infection is one of the top causes of attacks and requires vigorous treatment. By using this site, you agree to the Terms of Use and Privacy Policy. Barbiturates and Primidone must be avoided as they commonly precipitate symptoms. The disorder results in a form of non hemolytic jaundicewhich results in high levels of unconjugated bilirubin and often leads to brain damage in infants.


In Crigler—Najjar enfermdad and Gilbert syndrome, routine liver enfremedad tests are normal, and hepatic histology usually is normal, too. This article needs additional citations for verification.

Subsequent treatment with anti-psychotics increases the accumulation of porphobilinogen, thus aggravating the disease enough that it may prove fatal. Patients with AIP are commonly misdiagnosed with psychiatric diseases. An Orphanet summary for this disease is currently under development.

Disorders of heme biosynthesis: Under normal circumstances, heme synthesis begins in the mitochondrionproceeds into the cytoplasmand finishes back in the mitochondrion. Signs and symptoms of AIP can be variable. Dubin—Johnson syndrome Rotor syndrome. It is caused by abnormalities in the gene coding for uridine diphosphogluconurate glucuronosyltransferase UGT1A1. Side-effects are rare but can be serious.

These heme -like substances, in theory, inhibit ALA synthase and, hence, the accumulation of toxic precursors. This syndrome is divided into types I and II, with the latter sometimes called Arias syndrome. Only comments written in English can be processed. Ebfermedad syndrome Crigler—Najjar syndrome Lucey—Driscoll syndrome.

Earl Enfermedax from University of Maryland performed the first successful clinical trial. The American Porphyria Foundation has information regarding the quick procurement of the drug. Treatment can be problematic: ALAD porphyria Acute intermittent porphyria.
