Overview
If left untreated, neonatal jaundice may lead to brain damage. Common complications of neonatal jaundice include acute bilirubin encephalopathy and kernicterus. Prognosis of neonatal jaundice is excellent with the proper treatment.
Natural history, complications and prognosis
Natural history
- If left untreated, neonatal jaundice may develop bilirubin related brain damage.
Complications
- Common complications of neonatal jaundice include the following:
- Acute bilirubin encephalopathy:[1][2][3]
- Bilirubin is toxic to the brain and high levels may cause acute bilirubin encephalopathy.
- In the beginning, it may be asymptomatic or the infant is sleepy and hypotonic.
- If the encephalopathy not diagnosed early, more complications will develop as lethargy, seizures, inability to feed, and apnea in severe cases.
- It is better to diagnose it early in order not to develop severe cases of encephalopathy.
- Kernicterus:[4][5]
- Kernicterus is the chronic neurologic dysfunction that results from high levels of bilirubin.
- Kernicterus occurs due to damage of the basal ganglia with the precipitating bilirubin.
- Kernicterus can present with the following features:
- Hearing impairement
- Gaze abnormality
- Cerebral palsy like features
- The neurological manifestations of Kernicterus are reversible with exchange transfusion and decreasing the high bilirubin levels.
- Acute bilirubin encephalopathy:[1][2][3]
Prognosis
- Prognosis of neonatal jaundice is excellent with receiving the proper treatment.
