Evaluation of indocyanine green clearance and model for end-stage liver disease for estimation of short-term prognosis in decompensated cirrhosis.

BACKGROUND: Indocyanine green (ICG) clearance has been proposed as a quantitative liver function test several decades ago. Interest in this method has been renewed following the development of finger pulse densitometry for noninvasive estimation of the ICG plasma disappearance rate (PDR). On the other hand, the model for end-stage liver disease (MELD), which is based on routine laboratory parameters, is widely used for estimation of short-term survival in cirrhosis, but its prognostic value in critically ill cirrhotic patients is unclear. AIMS: The aim of the present study was to compare the diagnostic accuracy of ICG PDR vs. MELD for estimation of short-term prognosis in cirrhotic patients. METHODS: Ninety consecutive cirrhotic patients who were admitted for decompensated disease or were being evaluated for liver transplantation were screened. Patients who underwent liver transplantation within the following 90 days and those with hepatocellular carcinoma were excluded. In the remaining 70 patients, routine laboratory parameters and ICG clearance were analysed. Following an injection of ICG 0.25 mg/kg, PDR was measured by finger pulse densitometry. The diagnostic accuracy of ICG PDR and MELD for prediction of 90-day survival was assessed by receiver-operating characteristic (ROC) curve analysis. RESULTS: ROC curve analysis revealed superior diagnostic accuracy for MELD as compared with ICG PDR in predicting 90-day survival (area under the ROC curve 0.89 vs. 0.71). A MELD cut-off of 22 provided the best discrimination for prediction of 90-day survival. CONCLUSIONS: MELD is superior to ICG PDR for estimation of short-term survival in patients with decompensated cirrhosis.

Fatal hemobilia resulting from an iatrogenic arteriobiliary fistula as a rare complication of transjugular liver biopsy.

Transjugular liver biopsy is an important tool for diagnosing and/or staging of advanced liver disease. This procedure is considered safe even in the presence of severe coagulopathy, although rare fatal complications have been described. We herein report the first case of fatal hemobilia after transjugular liver biopsy. A patient with alcoholic liver cirrhosis developed hematemesis 1 day after transjugular liver biopsy. Upper gastrointestinal endoscopy revealed bleeding from the papilla of Vater. Despite early intervention by angiography and embolization of an arteriobiliary fistula, the patient deteriorated and ultimately died due to multiorgan failure.

Atorvastatin in patients with primary biliary cirrhosis and incomplete biochemical response to ursodeoxycholic acid.

UNLABELLED: Statin therapy may target both hypercholesterolemia and cholestasis in primary biliary cirrhosis (PBC). However, little is known about the efficacy and safety of statins in PBC. The aim of this single-center study was therefore to prospectively examine the effects of atorvastatin on serum markers of cholestasis, aminotransferases, and lipid and bile acid metabolism as well as inflammatory and immunological markers in patients with PBC. Fifteen patients with early-stage PBC and an incomplete biochemical response to ursodeoxycholic acid (UDCA) therapy (defined as alkaline phosphatase 1.5-fold above the upper limit of normal after 1 year) were treated with atorvastatin 10 mg/day, 20 mg/day, and 40 mg/day for 4 weeks, respectively. Serum levels of alkaline phosphatase increased during atorvastatin 20 mg and 40 mg (P < 0.05), whereas leucine aminopeptidase and gamma-glutamyltransferase remained unchanged. No statistical differences in overall serum ALT, AST, bilirubin, and IgM levels were observed. However, atorvastatin was discontinued in 1 out of 15 patients because of ALT 2-fold above baseline, and 2 patients showed ALT elevations 3-fold above the upper limit of normal at the end of the atorvastatin treatment period. Serum total cholesterol and low-density lipoprotein cholesterol levels decreased by 35% and 49%, respectively (P < 0.001). Precursors of cholesterol biosynthesis (lanosterol, desmosterol, lathosterol) showed a similar pattern. No changes in serum bile acid levels and composition were observed during treatment. CONCLUSION: Atorvastatin does not improve cholestasis in PBC patients with an incomplete biochemical response to UDCA but effectively reduces serum cholesterol levels.
