Haptoglobin type and liver disease

The haptoglobin phenotype has been estimated in patients suffering from chronic liver disease (n = 222) and acute hepatitis (n = 59) in comparison with the haptoglobin pattern of a normal population (n = 1726). The frequency of Hp 1-1 was significantly increased in non-alcoholic chronic liver disease (p = 5%; chi 2-test) in contrast to alcoholic disease. The highest incidence of Hp 1-1 occurred in cryptogenic cases (p = 1%). The follow-up of patients suffering from acute hepatitis failed to indicate any relationship between the haptoglobin phenotype and the course of hepatitis. The results suggest that Hp 1-1 is a genetic marker of special kinds of chronic liver diseases.
