Neonatal gallbladder enlargement and alpha 1-antitrypsin deficiency

Area of Science:

• Neonatology
• Hepatology
• Medical Genetics

Background:

• Alpha 1-antitrypsin deficiency is a genetic disorder that can affect the liver and lungs.
• Neonatal presentation often includes prolonged obstructive jaundice due to liver disease.
• Gallbladder abnormalities are not commonly associated with this condition in newborns.

Observation:

• A neonate with alpha 1-antitrypsin deficiency presented with significant gallbladder enlargement.
• This finding is atypical for the usual neonatal presentation of the condition.
• The gallbladder enlargement might be linked to concurrent cystic duct hypoplasia or atresia.

Findings:

• The patient's presentation included gallbladder enlargement alongside signs suggestive of obstructive jaundice.
• Alpha 1-antitrypsin deficiency was confirmed in the patient.
• The co-occurrence suggests a potential association between the deficiency and biliary tract anomalies.

Implications:

• Gallbladder enlargement should be considered in the differential diagnosis of neonates with prolonged obstructive jaundice.
• This case expands the spectrum of clinical presentations for alpha 1-antitrypsin deficiency in the neonatal period.
• Early consideration of alpha 1-antitrypsin deficiency may facilitate timely diagnosis and management in affected infants.
