[Neonatal intrahepatic cholestasis and alpha-1-antitrypsin deficiency (author's transl)]
Insights
Alpha-1-antitrypsin deficiency (AATD) in an infant (Pi ZZ) caused severe liver disease with cholestasis and fibrosis. Early diagnosis and family screening are crucial for managing this genetic condition.
Area of Science:
- Pediatric Hepatology
- Genetic Liver Diseases
- Gastroenterology
Background:
- Alpha-1-antitrypsin deficiency (AATD) is an inherited disorder that can lead to liver and lung disease.
- The Pi ZZ phenotype is associated with the most severe form of AATD, leading to reduced functional AAT protein.
- Intrahepatic cholestasis in infancy is a critical condition requiring prompt diagnosis and management.
Observation:
- A case report of an 11-month-old infant with the Pi ZZ phenotype of AATD is presented.
- The infant presented with intrahepatic cholestasis, jaundice, and hepatomegaly within the first few months of life.
- Liver biopsy revealed hepatic fibrosis, confirming significant liver damage.
Findings:
- The study details the clinical, biochemical, and pathological findings in an infant with AATD-associated liver disease.
- Analysis included Pi phenotypes, serum AAT levels, and family history, highlighting the genetic basis.
- The findings underscore the severe presentation of AATD in infancy.
Implications:
- This case highlights the importance of early recognition of AATD in infants presenting with cholestatic liver disease.
- Genetic screening and family evaluation are essential for identifying at-risk individuals.
- Understanding the clinical spectrum of AATD is vital for timely intervention and improved patient outcomes.
Abstract:
A case of alpha-1-antitrypsin deficiency in an 11 month-old Pi ZZ infant is reported. The patient exhibited intrahepatic cholestasis in the first months of life, with jaundice and hepatomegaly. Liver biopsy confirmed the diagnosis and showed the presence of hepatic fibrosis. Pi phenotypes, serum levels of alpha-1-antitrypsin, and symptoms in the family of the patient are reported. Clinical, biochemical and pathologic findings in liver disease in alpha-1-antitrypsin deficiency are discussed.
