| 1 | Non-invasive diagnosis of alcoholic liver disease显示文摘Alcoholic liver disease(ALD)is the most common liver disease in the Western world.For many reasons,it isunderestimated and underdiagnosed.An early diagnosis is absolutely essential since it(1)helps to identify patients at genetic risk for ALD;(2)can trigger efficient abstinence namely in non-addicted patients;and(3)initiate screening programs to prevent life-threateningcomplications such as bleeding from varices,spontaneous bacterial peritonitis or hepatocellular cancer.The two major end points of ALD are alcoholic liver cirrhosis and the rare and clinically-defined alcoholic hepatitis(AH).The prediction and early diagnosis of both entities is still insufficiently solved and usually relies on acombination of laboratory,clinical and imaging findings.It is not widely conceived that conventional screeningtools for ALD such as ultrasound imaging or routine laboratory testing can easily overlook ca.40%of manifest alcoholic liver cirrhosis.Non-invasive methods such as transient elastography(Fibroscan),acoustic radiation force impulse imaging or shear wave elastography have significantly improved the early diagnosis of alcoholiccirrhosis.Present algorithms allow either the exclusion or the exact definition of advanced fibrosis stages in ca.95%of patients.The correct interpretation of liver stiffness requires a timely abdominal ultrasound and actual transaminase levels.Other non-invasive methods such as controlled attenuation parameter,serum levels of M30 or M65,susceptometry or breath tests are under current evaluation to assess the degree of steatosis,apoptosis and iron overload in these patients.Liver biopsy still remains an important option to rule out comorbidities and to confirm the prognosis namely for patients with AH. | Sebastian Mueller Helmut Karl Seitz Vanessa Rausch | 2014 | World Journal of Gastroenterology2014，20，40： | 15 |
| 2 | Increased liver stiffness in alcoholic liver disease:Differentiating fibrosis from steatohepatitis显示文摘AIM:To test if inflammation also interferes with liver stiffness (LS) assessment in alcoholic liver disease (ALD) and to provide a clinical algorithm for reliable fibrosis assessment in ALD by FibroScan (FS).METHODS:We first performed sequential LS analysis before and after normalization of serum transaminases in a learning cohort of 50 patients with ALD admitted for alcohol detoxification. LS decreased in almost all patients within a mean observation interval of 5.3 d. Six patients (12%) would have been misdiagnosed with F3and F4 fibrosis but LS decreased below critical cut-off values of 8 and 12.5 kPa after normalization of trans-aminases. RESULTS:Of the serum transaminases,the decrease in LS correlated best with the decrease in glutamic oxaloacetic transaminase (GOT). No significant chang-es in LS were observed below GOT levels of 100 U/L. After establishing the association between LS and GOT levels,we applied the rule of GOT < 100 U/L for reliable LS assessment in a second validation cohort of 101 patients with histologically confi rmed ALD. By ex-cluding those patients with GOT > 100 U/L at the time of LS assessment from this cohort,the area under the receiver operating characteristic (AUROC) for cirrhosis detection by FS improved from 0.921 to 0.945 while specificity increased from 80% to 90% at a sensitivity of 96%. A similar AUROC could be obtained for lower F3 fibrosis stage if LS measurements were restricted to patients with GOT < 50 U/L. Histological grading of inflammation did not further improve the diagnostic accuracy of LS.CONCLUSION:Coexisting steatohepatitis markedly increases LS in patients with ALD independent of fibrosis stage. Postponing cirrhosis assessment by FS during alcohol withdrawal until GOT decreases to < 100 U/mL signif icantly improves the diagnostic accuracy. | Sebastian Mueller Gunda Millonig Lucie Sarovska Stefanie Friedrich Frank M Reimann Maria Pritsch Silke Eisele Felix Stickel Thomas Longerich Peter Schirmacher Helmut Karl Seitz | 2010 | World Journal of Gastroenterology2010，16，8： | 10 |
