Independent prognostic predictors of short-term HBV-ACLF mortality include the Child-Turcotte-Pugh（CTP） score, the model for end-stage liver disease（MELD） score, other MELD-based indices and the dynamic changes in these indices. The aims of this study were to evaluate the existing prognostic scores in a large cohort of HBV-ACLF patients and create a new predictive model. We retrospectively reviewed 392 HBV-ACLF patients from December 2008 to November 2011 and evaluated their 3-month survival. The predictive accuracy of CTP, MELD and MELD-based indices and the dynamic changes in the MELD-related scores（Δ scoring systems） upon admission and after two weeks of treatment were compared using the area under the receiver operating characteristic（ROC） curve method. Life-threatening factors and a series of bio-clinical parameters were studied by univariate and multivariate analyses. Among the existing scores, MELD had the best predictive ability. However, our new regression model provided an area under the curve of 0.930±0.0161（95% CI： 0.869 to 0.943）, which was significantly larger than that obtained with the MELD score at admission and after two weeks of treatment as well as with the dynamic changes of the MELD score（0.819, 0.921, and 0.826, respectively）（Z=3.542, P=0.0004）. In a large cohort of patients retrospectively reviewed for this study, our prognostic model was superior to the MELD score and is, therefore, a promising predictor of short-term survival in patients with HBV-ACLF.展开更多

Several risk factors that predict early rebleeding and mortality have been studied and there is no similar study in our country, so the aim of this study was to identify the risk factors of early rebleeding and mortality after bleeding episode in cirrhotic patients in Yemen. Patients and Method: It was a prospective study of cirrhotic patients with AVH who were admitted to the main public hospitals in Sana’a between April 2014 and March 2015. Demographic information, medical histories, physical examination findings, and laboratory test results were collected. Endoscopic and pharmacologic treatment was performed. The patients were followed up since admission and up to 6 weeks for the occurrence of rebleeding and mortality after the acute attack. Univariate and multivariate analyses were performed to identify independent risk factors for rebleeding and mortality. Survival analysis was estimated using the Kaplan-Meier method. Result: A total of 102 patients were analyzed. 26 patients (25.5%) rebleeded within 6 weeks period. The predictive factors significantly associated with rebleeding within 6 weeks period in univariate analysis were clot on varix at index endoscope (P - 47.29, P = 0.001) and high serum bilirubin (- 1.19, P = 0.01). Sixteen patients died (15.7%) within 6 weeks period. Predictors of mortality with significant difference in univariate analysis were hypovolemic shock (P = 0.001), high WBCs count (P - 1.41, P - 1.40, P < 0.05) were independent risk factors for mortality within 6 weeks period. Conclusion: Early rebleeding in cirrhotic patients with AVH was associated with clot on varix at endoscope and high serum bilirubin more than 3 mg/dl. Early mortality rate was associated with high MELD score (≥19) and WBCs over 10.3 × 10<sup>9</sup>/l.展开更多
