[Liver diseases in alpha 1 antitrypsin deficiency syndrome in children]
1II. Kinderklinik, Klinikums Berlin Buch, DDR.
Insights
Approximately 15% of children with alpha-1-antitrypsin deficiency (PI-ZZ) develop severe liver disease. Early recognition and management are crucial for successful liver transplantation, the only cure.
Area of Science:
- Pediatrics
- Genetics
- Hepatology
Context:
- Alpha-1-antitrypsin deficiency (AATD) is a genetic disorder.
- Proteinase inhibitor type ZZ (PI-ZZ) is the most severe form of AATD.
- Hepatopathy affects approximately 15% of PI-ZZ children, often presenting as severe cholestatic hepatitis in infancy.
Purpose:
- To highlight the challenges in managing PI-ZZ-related hepatopathy in children.
- To emphasize the importance of early diagnosis and intervention.
- To stress the critical role of liver transplantation and genetic counseling.
Summary:
- PI-ZZ AATD can lead to severe, progressive liver disease (hepatopathy) in children.
- Symptoms like cholestatic hepatitis and hepatic cirrhosis may appear in early infancy.
- Liver transplantation is the only definitive treatment, requiring careful pre-transplant management.
Impact:
- Early identification of PI-ZZ AATD is possible even without specialized labs.
- Optimizing patient condition for liver transplantation is key.
- Genetic counseling is vital for families due to the hereditary nature of PI-ZZ AATD.
Abstract:
About 15% of children with alpha-1-antitrypsin-deficiency with proteinase inhibitor type ZZ develop hepatopathy, uninfluenceable in its course. These children already show symptoms of severe cholestatic hepatitis in early infancy as became obvious from data of 13 children being patients in the authors care and suffering from hepatic cirrhosis with alpha-1-antitrypsin-deficiency. At present liver transplantation is the only causal possibility of therapy. Even without highly specialized laboratory the non-laboratory assistant will recognize at least the homozygous alpha-1-antitrypsin-deficiency (PI-ZZ). The therapeutic approach must be directed on treating the patients in such a way that liver transplantation will be possible at a favourable moment and under good conditions. Since PI-ZZ family members suffer similar course of hepatopathy, genetic counsel is of special significance.
