Overview
Neonatal jaundice is caused by hemolysis of the RBCs mainly due to either intravascular causes or extravascular causes. Other causes include nonhemolytic causes as cephalosporines induced jaundice, genetic mutaitons of the UGT enzyme, and hepatic causes.
Causes
Common causes
- Common causes of neonatal jaundice include the following:
- Increase bilirubin production due to hemolysis. Hemolytic causes include the following:
- Intrinsic causes of hemolysis
- Increase bilirubin production due to hemolysis. Hemolytic causes include the following:
- Systemic contitions
- Enzyme conditions
- Glucose-6-phosphate dehydrogenase deficiency (also called G6PD deficiency)
- Pyruvate kinase deficiency
- Globin synthesis defect
Extrinsic causes of hemolysis
- Alloimmunity (The neonatal or cord blood gives a positive direct Coombs test and the maternal blood gives a positive indirect Coombs test)
Non-hemolytic causes
Hepatic causes
- Infections
- Metabolic
- Drugs- Losartan and Hydrochlorothiazide
- Total parenteral nutrition
- Idiopathic
Post-hepatic
