[Transfer of antibiotics into the liver tissue of infants with hepatic dysfunction]
Insights
Antibiotic transfer into liver tissues is poor in jaundiced infants with liver dysfunction. This study suggests low cefmetazole (CMZ) liver uptake contributes to poor bile excretion in these infants.
Area of Science:
- Pediatric Hepatology
- Pharmacokinetics
- Neonatal Medicine
Context:
- Investigating antibiotic disposition in infants with congenital liver conditions.
- Assessing cefmetazole (CMZ) transfer into liver tissue in cases of hepatic dysfunction.
- Examining infants with congenital biliary atresia, bile duct dilatation, biliary hypoplasia, hepatic hemangioma, and congenital heart disease.
Purpose:
- To determine the transfer rate of cefmetazole (CMZ) into the liver tissues of infants with hepatic dysfunction.
- To explore the relationship between CMZ liver tissue levels and its excretion into bile.
- To identify potential causes for poor CMZ bile excretion in jaundiced infants.
Summary:
- This study reports on cefmetazole (CMZ) transfer into liver tissues in infants with various congenital liver conditions and hepatic dysfunction.
- Liver tissue CMZ levels were found to be extremely low in infants with hepatic dysfunction.
- Poor CMZ transfer into liver tissues is proposed as a primary reason for inadequate CMZ excretion into bile in jaundiced infants.
Impact:
- Highlights a potential pharmacokinetic challenge in treating jaundiced infants with hepatic dysfunction.
- Suggests that impaired drug transfer to the liver may necessitate alternative therapeutic strategies.
- Provides insights into cefmetazole (CMZ) disposition in a vulnerable pediatric population.
Abstract:
Transfer of antibiotic (cefmetazole, CMZ) into the liver tissues of the infant with hepatic dysfunction, 6 cases of congenital biliary atresia, 4 cases of congenital bile duct dilatation, 1 case of congenital biliary hypoplasia, hepatic hemangioma and umbilical hernia with congenital heart disease is reported here. CMZ level in the liver tissues with hepatic dysfunction shows extremely low. Our study revealed that poor transfer of CMZ into the liver tissues might be a main cause of the poor excretion of CMZ into the bile in case of jaundiced infant.
