Alternative titles and symbols : Neonatal hepatitis; Giant cell hepatitis; Alloimmune hepatitis, congenital; NH; NHC;
Description : Neonatal hemochromatosis (NH) is characterized by hepatic failure in the newborn period
and heavy iron staining in the liver. In addition, there is marked siderosis of extrahepatic
tissues, including the heart and pancreas (Driscoll et al., 1988). Whitington (2007)
postulated that some cases of neonatal hemochromatosis result from maternal alloimmunity
directed at the fetal liver, and therefore do not represent an inherited mendelian
disorder. Other causes may result from metabolic disease or perinatal infection. In
particular, he commented that the disorder is not related to the family of inherited
liver diseases that fall under the classification of hereditary hemochromatosis (see,
e.g., 235200). Whitington (2007) proposed the term 'congenital alloimmune hepatitis.'
In the past, the disorder has loosely been labeled 'neonatal hepatitis' and 'giant
cell hepatitis,' which are pathologic findings in the liver representing a common
response to a variety of insults, including cholestatic disorders and infection, among
others (Fawaz et al., 1975; Knisely et al., 1987; Kelly et al., 2001).;
