Abstract

Two cases of scleroderma and primary biliary cirrhosis are described. One had systemic sclerosis with primary biliary cirrhosis of six years' duration at the stage of ductular proliferation. The other had the C.R.S.T. syndrome (calcinosis, Raynaud's phenomenon, sclerodactyly, and telangiectases) with primary biliary cirrhosis at the florid stage. Several similar cases were found in a review of other reports, and it is suggested that the association may be due to a common "autoimmune" process.

Augmented expression of hepatocytes growth factor activator inhibitor type 1 (HAI-1) in intrahepatic small bile ducts in primary biliary cirrhosis.

The repair system of damaged biliary mucosa was not fully clarified so far in primary biliary cirrhosis (PBC). Given that related factors of the hepatocyte growth factor (HGF) such as HGF activator (HGFA) and HGFA inhibitor type 1 (HAI-1) participate in the repair of injured gastrointestinal mucosa, we investigated the involvement of the HGF/HGFA/HAI-1 system in PBC and control livers. The expression of HGFA, HAI-1, and c-Met was examined in PBC livers (n=24), diseased livers (control, n=30), and normal livers (n=15) by immunohistochemistry and semiquantitative reverse transcriptase-polymerase chain reaction. We examined the expression of HGFA, HAI-1, and c-Met, and the effect of HGF administration on cell proliferation and wound healing, and HAI expression in cultured mouse biliary epithelial cells (BECs). HAI-1 expression was faint in control livers, whereas it was significantly augmented in damaged small bile ducts, bile ductules, and periportal hepatocytes in PBC (p<0.05). HGFA and c-Met were homogeneously expressed in BECs in PBC and control livers. HAI-1 expression was increased at the front of wound healing and the treatment with HGF-enhanced HAI-1 expression, cell proliferation, and wound healing in cultured BECs. HGF/HGFA/HAI-1 system may participate in biliary mucosal repair as reported in gastrointestinal mucosal repair.

Hepatic expression of galectin-3 and receptor for advanced glycation end products in patients with liver disease.

BACKGROUND: Advanced glycation end products (AGEs) are a heterogeneous group of glycosylated proteins (of which carboxymethyl-lysine (CML) is the most common) which accumulate during ageing processes and play an important role in the pathogenesis of a variety of chronic diseases. Impaired hepatic function might result in elevated levels of AGEs, as the liver represents the major site of AGE metabolism. The actions of AGEs are mediated by various receptors, among which the AGE-receptor complex (including galectin-3 as an essential part) is thought to have a cytoprotective effect, and receptor for advanced glycation end product (RAGE) a cytotoxic effect. AIM: To assess the relationship between CML and expression of galectin-3 and RAGE in different histological structures in biopsy specimens from patients with varying degrees of liver impairment. METHOD: Immunohistochemical staining of 164 biopsies from patients with varying degrees of liver impairment was performed to determine the levels of CML, galectin-3 and RAGE in hepatocytes, Kupffer cells and bile ducts by a semiquantative score. RESULTS: Independent of diagnosis, CML and RAGEs were detected in hepatocytes, whereas galectin-3 was present only in hepatocytes of cirrhotics. By contrast, CML and galectin-3 were highly expressed in Kupffer cells (well correlating levels, highest scores in cholestasis) whereas expression of RAGEs was not significant. All three assessed biochemical markers showed their highest levels of expression/detection in bile ducts. CONCLUSION: These findings indicate an increased susceptibility of hepatocytes to the detrimental effects of AGEs and underline the protective function of Kupffer cells. Furthermore, the biliary system seems to play an important role in the disposition of AGEs.
