Our approach begins with a thorough review of medical records and imaging studies. There are multiple benign and malignant malformations or tumors that can occur in the liver of a child. We also have a frank discussion with the patient and family about what is involved in the evaluation for a life-saving liver transplant. Our approach to pediatric patients with this problem is to start with a thorough history and physical examination and nutritional assessment.

Cirrhosis or Chronic Liver FailureĬirrhosis or chronic liver failure can be caused by a number of the liver and biliary diseases listed in Clinical Services or sometimes appear without known cause. Some patients may have minimal liver disease during their entire lifetime however, a small number will eventually require liver transplant. Liver function tests are followed over time. It is difficult to predict how severely a liver will be affected. Vaccinations to protect against viruses, such as hepatitis A and hepatitis B, that can further damage the liver should be given. To protect their lungs, it is very important that the affected person and those around them not smoke. Therapy involves controlling symptoms and attempting to prevent the development of complications. The amount of liver swelling and damage can be assessed by ultrasonography (sonogram) of the abdomen, blood tests of liver inflammation and function and a liver biopsy, where a small piece of liver tissue is obtained and then examined under the microscope to search for changes typical of A1AT deficiency. In rare cases, a more detailed analysis of the DNA in the gene may be necessary. When a low A1AT level is found, an additional test is usually done to identify the types of abnormal A1AT proteins that are in the circulation. In cases of A1AT deficiency, the serum A1AT level will be low. The standard screening test is to measure the amount of A1AT protein in the circulation. Testing is usually done when a child has liver inflammation of uncertain cause or when a family history suggests A1AT liver disease. Adults with A1AT deficiency may have difficulties with chronic obstructive pulmonary disease (COPD), emphysema, chronic bronchitis, asthma, coughing and repeated lung infections. Lung disease usually develops only in adulthood. Older children and teens can present with a liver that has been inflamed for a long time, causing scarring (cirrhosis) to develop. Newborns may develop jaundice as part of inflammation of the liver associated with A1AT deficiency. SymptomsĪbout 10 percent of newborns with liver disease will be diagnosed with A1AT deficiency. Although carrier parents partially produce the abnormal A1AT protein, they usually have no - or very minimal - symptoms and they may not realize they are partially affected until their child is diagnosed with the condition. Both parents must be carriers of the genetic defect to have a child with A1AT deficiency. The defective A1AT protein that remains in the liver may cause liver inflammation ( hepatitis) that can progress to cirrhosis (permanent liver scarring) and liver failure.Ī1AT deficiency is quite common, with about 1 in 1,500 to 2,000 people affected. When the A1AT protein is deficient in the circulation, tissue inflammation and tissue damage is more severe, especially in the lungs. A1AT is a specialized protein that blocks the action of other proteins important in inflammation (swelling) and breakdown of tissues in the body. This causes a deficiency of the A1AT protein in the circulation. What is alpha-1 antitrypsin deficiency?Īlpha-1 antitrypsin (A1AT) deficiency is an inherited disease in which a protein known as A1AT is unable to be released from the liver into the blood in adequate amounts. We are committed to serving children with this disorder as soon as we are notified and work with our emergency transport team, intensive care specialists and if necessary, our pediatric liver surgeons to provide 24-hour care for the best outcome possible for children with this condition. Jaundice occurs rapidly, often in concert with gastrointestinal symptoms like vomiting and fever. This alarming syndrome usually occurs in a previously well infant, child or adolescent and can be caused by a number of infectious or metabolic causes and reactions to medication.
