Prognostic factors of the outcome of upper gastrointestinal bleeding in patients with cirrhosis are insufficiently defined. Pertinent clinical, biochemical, and endoscopic data of 332 upper gastrointestinal bleedings in 268 patients with cirrhosis observed in the participating centers during 31 months were recorded. Clinical data were analyzed until 40 days after bleeding. A further set of 82 bleedings was used as a validation group. Ninety-two of the 268 patients died within the time of the study, and 28 of the 82 patients of the validation group died. According to a stepwise logistic regression analysis, s-creatinine, ascites on admission, previous diagnosis of hepatocellular carcinoma, s-bilirubin, prothrombin index, varices as definite or probable source of bleeding, gender, and presentation with hemathemesis were the best set of covariates for predicting outcome. From them a prognostic index was developed and validated in the 82 further bleedings. Sensitivity and specificity in the cumulated training and test sets were 75 and 80%, respectively. In the present material, the prognostic index was significantly more efficient than Child-Pugh score or the prognostic index proposed by Garden et al. These data show that it is possible to predict the outcome of upper gastrointestinal bleeding in cirrhosis on the basis of few easily available data. The prognostic index we proposed and validated may become useful to predict the outcome of a bleeding and to select or stratify patients in clinical trials.
肝硬化患者上消化道出血预后因素的界定尚不充分。记录了参与研究中心在31个月内观察到的268例肝硬化患者发生的332次上消化道出血的相关临床、生化及内镜数据。对出血后40天内的临床数据进行分析。另外82次出血作为验证组。268例患者中有92例在研究期间死亡,验证组的82例患者中有28例死亡。根据逐步逻辑回归分析,血清肌酐、入院时腹水、既往肝细胞癌诊断、血清胆红素、凝血酶原指数、明确或可能为出血来源的静脉曲张、性别及呕血表现是预测预后的最佳协变量组合。据此制定了一个预后指数,并在另外82次出血中进行验证。累积训练集和测试集的敏感性和特异性分别为75%和80%。在本研究资料中,该预后指数比Child-Pugh评分或Garden等人提出的预后指数效率显著更高。这些数据表明,基于少数易于获得的数据就有可能预测肝硬化患者上消化道出血的预后。我们提出并验证的预后指数可能有助于预测出血的预后,并在临床试验中选择患者或对患者进行分层。
