What type of bilirubin is elevated in Crigler Najjar syndrome?
People with Crigler-Najjar syndrome have a buildup of unconjugated bilirubin in their blood (unconjugated hyperbilirubinemia). Bilirubin has an orange-yellow tint, and hyperbilirubinemia causes yellowing of the skin and whites of the eyes (jaundice).
What level of bilirubin is toxic?
Although the risk of bilirubin toxicity is probably negligible in a healthy term newborn without hemolysis,9 the physician should become concerned if the bilirubin level is above 25 mg per dL (428 μ mol per L). In the term newborn with hemolysis, a bilirubin level above 20 mg per dL (342 μ mol per L) is a concern.
What level bilirubin causes brain damage?
Kernicterus, or bilirubin encephalopathy, is bilirubin-induced neurological damage, which is most commonly seen in infants. It occurs when the unconjugated bilirubin (indirect bilirubin) levels cross 25 mg/dL in the blood from any event leading to decreased elimination and increased production of bilirubin.
When should bilirubin levels be rechecked?
Recheck bilirubin q 4-6 hours, depending on the rate of decline, when treating with exchange transfusion. A neonate being treated with home phototherapy (fiber optic blanket, Bili Blanket) should have a TSB checked: – Every 24-48 hours if the neonate is > 38 weeks gestation.
What is the difference between Gilbert syndrome and Crigler-Najjar?
Symptoms of this disorder (if any) may result from reduced activity of the liver UGT1A1 enzyme. Gilbert syndrome is caused by mutations of the same gene that causes Crigler-Najjar syndrome, but affected individuals maintain about one third of the normal activity of the UGT1A1 enzyme.
What is considered very high bilirubin?
Typically, bilirubin levels fall somewhere between 0.3 and 1.0 milligrams per deciliter (mg/dL). Anything above 1.2 mg/dL is usually considered elevated.
How long can you live with high bilirubin levels?
Ninety-five per cent confidence limits on survival time were 32-74 months. If two successive six month bilirubin values exceeded 102 mumol/l (6.0 mg/dl), calculated survival time was 25 months, and if two successive six month bilirubin values exceeded 170 mumol/l (10.0 mg/dl), survival time was 17 months.
Should I be worried about high bilirubin levels?
Lower than normal bilirubin levels are usually not a concern. Elevated levels may indicate liver damage or disease. Higher than normal levels of direct bilirubin in your blood may indicate your liver isn’t clearing bilirubin properly.
Is high bilirubin life threatening?
Having high bilirubin levels can be dangerous and can lead to complications, especially in newborns. This can result in a condition known as kernicterus in which seizures, irreversible brain damage, and death can occur.
How can I lower my bilirubin fast?
However, following these four tips can help you boost overall liver health in addition to medical guidance.
- Stay hydrated. Staying hydrated helps lower bilirubin levels by facilitating the removal of waste from the body.
- Consume fresh fruits and vegetables.
- Increase your intake of fiber.
- Avoid alcohol.
How fast does bilirubin rise?
Bilirubin levels may rise again 18 to 24 hours after stopping phototherapy. Although rare, this requires follow-up for those who may need more treatment. Side effects — Phototherapy is very safe, but it can have temporary side effects, including skin rashes and loose stools.
How quickly does bilirubin decrease?
This helps to get rid of bilirubin. Jaundice usually clears up within 2 weeks in formula-fed babies. It may last for more than 2 to 3 weeks in breastfed babies. If your baby’s jaundice lasts more than 3 weeks, talk to his health care provider.
How high is bilirubin in Gilbert’s syndrome?
The normal total bilirubin ranges in a healthy patient varies between 0.0 to 1.0 mg/dL; from which 0.6 to 1 mg/dL correspond to unconjugated bilirubin. Patients with Gilbert syndrome can present fluctuating serum bilirubin levels ranging from normal to usually less than 3 mg/dL.
How do you test for Crigler-Najjar syndrome?
Molecular genetic testing can confirm a diagnosis of Crigler-Najjar syndrome. Molecular genetic testing can detect mutations in the UGT1A1 gene that are known to cause the disorder, but is available only as a diagnostic service at specialized laboratories.
What foods to avoid if you have high bilirubin?
Foods and drinks to avoid or limit during jaundice recovery include:
- Alcohol. Alcohol is toxic to most internal bodily tissues, including the liver.
- Refined carbohydrates.
- Packaged, canned, and smoked foods.
- Saturated and trans fats.
- Raw or undercooked fish or shellfish.
- Beef and pork.
How can I bring my bilirubin down?
If you have elevated bilirubin levels, you should take steps to lower them and promote liver health by making several changes to your diet. These changes include drinking more water, cutting back on your alcohol consumption, and eating more fruits and vegetables and fewer processed foods.
How do you treat high bilirubin?
Which medicine is best for bilirubin?
Phenobarbital therapy has been shown to be effective in reducing plasma bilirubin levels in patients with Crigler-Najjar syndrome type 2. Administration of 60-180 mg/day of the drug (in divided doses) can reduce serum bilirubin levels by at least 25%. A response should be expected within 2-3 weeks.
How do you get your bilirubin down?
Treatments to lower the level of bilirubin in your baby’s blood may include:
- Enhanced nutrition.
- Light therapy (phototherapy).
- Intravenous immunoglobulin (IVIg).
- Exchange transfusion.
What is a very high bilirubin level?
Can Gilbert’s cause liver damage?
Gilbert’s syndrome is a lifelong condition. But it does not require treatment because it does not pose a threat to health and does not cause complications or an increased risk of liver disease. Episodes of jaundice and any associated symptoms are usually short-lived and eventually pass.
How long can you live with high bilirubin?
The median survival time was 13 days (range 1-180). Nine patients died outside our service and were censored in survival analyses. The survival was 65.4% (95% CI 61.9-69.2) at 7 days, 17.7% (95% CI 15.0-20.9) at 30 days and 1.9% (95% CI 1.1-3.3) at 90 days.
What are the symptoms of Crigler-Najjar syndrome?

- Diarrhea.
- Vomiting.
- Fever.
- Confusion.

- Difficulty swallowing.
- Change in gait, staggering, frequent falling.
- Seizures.
What happens if bilirubin is high?
Lower than normal bilirubin levels are usually not a concern. Elevated levels may indicate liver damage or disease. Higher than normal levels of direct bilirubin in your blood may indicate your liver isn’t clearing bilirubin properly. Elevated levels of indirect bilirubin may indicate other problems.
