Chronic liver diseases are potentially evolving clinical situations which, independently by the etiology, could proceed towards progressive liver structural and functional impairments. The only efficient treatment is orthotopic liver transplantation. Chronic liver diseases, and up to 40% of liver cirrhosis, are initially asymptomatic, but cirrhosis is the most frequent cause of death among non-neoplastic digestive diseases. Important elements complicating a decompensated liver cirrhosis are ascites, hepatic encephalopathy, digestive bleeding and jaundice. Acute liver failure (ALF) is the expression of a clinical state, that is common to many conditions sharing severe liver structural and functional impairments. In patients affected by decompensated liver cirrhosis, ALF could be triggered by several factors, while the death is caused by bleeding episodes, hepato-renal syndrome, spontaneous bacterial peritonitis or hepatocarcinoma. In patients affected by chronic liver diseases, the diagnosis of ALF is based on progressively increasing jaundice, encephalopathy and coagulopathy. Recent clinical trials have evaluated the efficacy of extrahepatic liver support systems, either artificial or bio-artificial, in treating episodes of ALF in chronic liver patients. The preliminary results indicate a potential use of such systems in blood detoxification, but they also showed limits in increasing patient survival.

Fulminant hepatic failure (FHF) is defined as rapid acute liver injury, often complicated with spontaneous bacterial peritonitis (SBP). The precise onset of FHF with SBP is still unknown, but it is thought that SBP closely correlates with a weakened intestinal barrier. Dendritic cells (DCs) play a crucial role in forming the intestinal immune barrier, therefore the number, maturity and chemotactic ability of intestinal DCs were studied in FHF. Mouse intestinal and spleen DCs were isolated by magnetic-activated cell sorting (MACS) and surface markers of DCs, namely CD11c, CD74, CD83 and CD86, were identified using flow cytometry. Immunohistochemistry and Western blotting were performed to detect the distribution and expression of CC-chemokine receptor 7 (CCR7) and CC-chemokine receptor 9 (CCR9), as well as their ligands-CC-chemokine ligand 21 (CCL21) and CC-chemokine ligand 25 (CCL25). Real-time PCR was used to detect CCR7 and CCR9 mRNA, along with their ligands-CCL21 and CCL25 mRNA. Flow cytometry analysis showed that the markers CD74, CD83 and CD86 of CD11c+DCs were lower in the D-galactosamine (D-GalN) group and were significantly decreased in the FHF group, while there were no significant changes in the expression of these markers in the lipopolysaccharide (LPS) group. Immunohistochemistry results showed that staining for CCR7 and CCR9, as well as their ligands CCL21 and CCL25, was significantly weaker in the D-GalN and FHF groups compared with the normal saline (NS) group or the LPS group; the FHF group even showed completely unstained parts. Protein expression of CCR7 and CCR9, as well as their ligands- CCL21 and CCL25, was also lower in the D-GalN group and decreased even more significantly in the FHF group. At the gene level, CCR7 and CCR9, along with CCL21 and CCL25 mRNA expression, was lower in the D-GalN group and significantly decreased in the FHF group compared to the NS and LPS groups, consisting with the protein expression. Our study indicated that intestinal DCs were decreased in number, maturity and chemotactic ability in FHF and might contribute to a decreased function of the intestinal immune barrier in FHF.

Hospitalists often care for patients with liver disease, including those with acute liver injury and failure and patients with complications of decompensated cirrhosis. Acute liver failure is a true emergency, requiring intensive care and oftentimes transfer of the patient to a liver transplant center. Patients with decompensated cirrhosis have complications of portal hypertension, including variceal hemorrhage, ascites, spontaneous bacterial peritonitis, and hepatic encephalopathy. These complications increase the risk of mortality among patients with decompensated cirrhosis. Comanagement by the hospitalist with gastroenterology/hepatology can optimize care, especially for patients being considered for liver transplant evaluation.
