| Abstract |
|
Tyrosinemia type I is an autosomal recessive disorder of amino acid metabolism and is caused by
a deficiency of fumarylacetoacetate hydrolase(FAH), the last enzyme in the catabolic pathway of
tyrosine. The disease is characterized by hepatic dysfunction, hepatocellular carcinomas, renal tubular
dysfunction, rickets, and neurologic crises. We experienced 2 cases(a 4-day-old girl, a 7-
month-old girl) of acute form of tyrosinemia type I. Case 1 was presented with tachypnea, vomiting
and prolonged PT and aPTT. Case 2 was presented with systemic jaundice, irritability, an
odor resembling boiled cabbage, and hepatic dysfunction. The diagnosis was made by demonstrating
elevated plasma levels of tyrsione and other amino acids, and urinary excretion of succinylacetone.
Both of the patients had a significant coagulopathy which was not treated by transfusion
of fresh frozen plasma and cryoprecipitate. We report two tyrosinemic infants who were
presented with severe coagulopathy. |
