Nonalcoholic steatohepatitis associated with psoriasis vulgaris.

A 24-year-old man was admitted to our hospital because of liver dysfunction. He had been diagnosed as having psoriasis vulgaris at 18 years of age. Physical examination demonstrated obesity, general erythema, and hepatomegaly. Laboratory data revealed elevated serum levels of aspartate aminotransferase, alanine aminotransferase, lactate dehydrogenase, and glucose. A histological examination of the liver revealed macrovesicular fatty change and infiltration of inflammatory cells, including lymphocytes and polymorphonuclear cells, within the liver lobules. Pericentral fibrosis and pericellular fibrosis were also recognized. He was diagnosed as having nonalcoholic steatohepatitis (NASH), based on the fact that he had no habit of drinking alcohol, as well as psoriasis vulgaris and diabetes mellitus. We herein report a very rare case of NASH associated with psoriasis vulgaris.

Reduced expression of low-density lipoprotein receptor in hepatocellular carcinoma with paraneoplastic hypercholesterolemia.

Background and Aim:  Hepatocellular carcinoma (HCC) is frequently associated with paraneoplastic hypercholesterolemia. In familial hypercholesterolemia, genetic mutation of the low‐density lipoprotein (LDL) receptor gene has been recognized as being a pathogenesis of the disease. We investigate the expression of a LDL receptor protein and gene abnormalities of a LDL receptor in HCC cells in cases with paraneoplastic hypercholesterolemia.

Hepatic expression of gamma-glutamyltranspeptidase in the human liver of patients with alcoholic liver disease

Background:  Gamma‐glutamyltranspeptidase (GGT) has been recognized as an enzyme that converts glutathione into cysteine, and it is localized predominantly within the liver. Serum GGT is clinically recognized as the most useful marker for diagnosis of alcoholic liver disease (ALD).
