Alpha 1-antitrypsin deficiency. Turning away from the infections, the metabolic causes of chronic liver disease in children, by far and away the most common is alpha 1-antitrypsin deficiency. And if you remember, this is, generally speaking, associated with the ZZ phenotype. Occasionally you see it with some of the other phenotypes like MZ, but for purposes of keeping life simple, it’s the ZZ phenotype, generally speaking. As I said before, these children may have presented in infancy with a high bilirubin which completely went away, the diagnosis may never have been made until they come into your office or in to the hospital in childhood and they’ve already developed signs of portal hypertension. Interestingly, the lung disease tends to occur quite late in alpha 1-antitrypsin deficiency, whereas the liver disease will present sometimes quite early. Sometimes the cirrhosis is fully established and portal hypertension with a non-jaundiced child with a big spleen and may be vomiting blood in the emergency room, is the first sign that this child had alpha 1-antitrypsin deficiency all along. Treatment? There really is none. It’s supportive care, if end-stage liver disease is already present, until you can get these children transplanted.

Cystic fibrosis. You normally think about this as being a disease involving the lungs. Interestingly, cirrhosis with portal hypertension can occur in cystic fibrosis, generally presenting in mid or older age children. Sometimes the liver disease is much more important than the lung disease in these children, and they may also present with portal hypertension and already developed cirrhosis. If they’ve got portal hypertension, you try to shunt some of these children if they are big enough, because of course we are very worried about transplanting children who may already have chronic lung disease and all the problems of immunosuppression and chronic lung disease together might cause.

Tyrosinemia. We heard about this in the infant age range. How about in children as a cause of chronic hepatitis? Tyrosinemia is an autosomal recessive disease. As we said, in infancy it is a fulminant presentation. In childhood, a chronic presentation. A very important thing about tyrosinemia in children is its association with hepatocellular carcinoma. Twenty-seven percent of children by their second birthday will already have HCC. So that’s why you really have to transplant these children, generally speaking, before the age of two in order to avoid this devastating complication. The other two systems that are involved are the central nervous system – neurologic crises, which can actually look like acute porphyria can occur – and renal impairment is also common. Making the diagnosis, we talked about. You measure the succinylacetone in the urine. In terms of treatment, you manipulate the diet to get rid of the offending precursor proteins and now there is an interesting alternative. A chemical agent, shortened to NTBC, and the importance of this is it actually halts tyrosine degradation so that you don’t form the toxic metabolite, which is succinylacetone. This can actually be very effective, particularly in the infants, but what we don’t think it does is we don’t think it stops the progression to hepatocellular carcinoma. So even though you can buy time for the little children, you probably still – at least as far as we know in 2006 – still have to transplant these little ones before their third birthday.
