BACKGROUND: Alcoholic hepatitis (AH) is a necrotizing inflammatory process caused by alcoholic liver injury. It carries a significant short-term mortality. The management of AH is challenging. Although corticosteroids have been demonstrated to exert anti-inflammatory and antifibrotic effects, their efficacy for the treatment of AH remains debatable. DATA SOURCES: A literature search was performed of MEDLINE, ScienceDirect, SpringerLink and Wiley InterScience using the key words 'alcoholic hepatitis', 'alcoholic liver disease', and 'corticosteroids'. The available data reported in the relevant literature were analyzed. RESULTS: More than 17 controlled trials and at least 13 meta-analyses have reported the efficacy of corticosteroids in the treatment of AH in the past 40 years. Many were poorly designed and used different inclusion/exclusion criteria, making it difficult to reach a consensus. In this review, we summarized all the controversial data in the past decade and analyzed the potential causes for the varying therapeutic effects of corticosteroids in AH. The focus of the controversy has changed from 'whether steroids are beneficial or harmful for AH patients' to 'how to accurately identify responders to steroids early and rationalize corticosteroid treatment'. An early response to glucocorticoids, as determined by calculating the Lille score after 7 days of treatment, has been shown to be a clinically useful indicator. Moreover, down-regulation of steroid sensitivity, risk of infection, and a rational therapeutic strategy of corticosteroids in AH patients are all crucial for therapeutic ***: An early and accurate determination of steroid sensitivity is important. Besides, we need to overcome the down-regulation of steroid sensitivity, reduce the infection risk and rationalize the therapeutic strategy of corticosteroids. A fresh perspective is needed on the use of corticosteroids in AH patients.

BACKGROUND:Decreased cardiac contractility has been observed in cirrhosis,suggesting a latent cardiomyopathy in these *** study was designed to evaluate left ventricular structure and function in patients with end-stage liver disease by the model for end-stage liver disease(MELD) scoring system. METHODS:We recruited 82 patients(72 male,10 female; mean age 50.3±8.9 years)with end-stage liver disease who underwent orthotopic liver transplantation between January 2002 and May ***-eight patients had cirrhosis and 4 had primary liver *** were categorized into three groups on the basis of MELD score:≤9(27 patients, 33%);10-19(40,49%);and≥20(15,18%).The relationship between MELD score and cardiac structure and function was *** assessments of blood biochemistry, blood coagulation,serum virology,echocardiography and electrocardiography were performed. RESULTS:MELD score was positively correlated with enlarged left atrial diameter,increased interventricular septum thickness(IVST),increased aortic flow,corrected QT interval (QTc)extension and cardiac output(P=0.033,0.002,0.000, 0.000 and 0.009,respectively).International normalized ratio also had a correlation with the above parameters and enlarged left ventricular end-diastolic diameter(P=0.043,0.010,0.000, 0.001,0.016 and 0.008,respectively).Serum creatinine was positively correlated with IVST(r=0.257,P=0.020),but negatively correlated with early maximal ventricular filling velocity/late diastolic or atrial velocity ratio(r=-0.300, P=0.006).A difference of QTc>440 ms among the three groups was statistically significant(χ2=9.791,P=0.007).CONCLUSIONS:Abnormalities in cardiac structure and function are common in patients with end-stage liver disease. MELD score is a practically useful approach for the assessment of cardiac function in such patients.
