Sixty-one patients with cirrhosis with varices without previous bleeding were admitted to our Department over a period of 2 yr. Fifty had alcoholic cirrhosis. Child-Turcotte-Pugh class was A in 11 patients, B in 30, and C in 20. Varices were F1 in 18, and F2-F3 in 43. During follow-up of up to 40 months, one patient was lost to follow-up and 22 patients died, seven of gastrointestinal bleeding and 15 of liver failure. The probability of death from any cause was significantly related to Child-Turcotte-Pugh class, ascites, encephalopathy, s-albumin, s-bilirubin, prothrombin index, and galactose elimination capacity. Independent prognostic variables according to Cox's model resulted s-albumin, s-bilirubin, encephalopathy, and varices. Considering only patients who died from liver failure, survival was univariately related to the same determinants, whereas the Cox's model individuated s-bilirubin, s-albumin, ascites, and galactose elimination capacity as independent prognostic indicators. Considering only patients who died from gastrointestinal bleeding no Cox model could be performed due to the small number of deaths. In patients with F1 varices, the probability of death from liver failure was 5 times higher than that from gastrointestinal bleeding; in patients with F2-F3 varices, liver failure and gastrointestinal bleeding each accounted for approximately half of the deaths. These data could become useful when programming a clinical trial of prophylaxis which considers reduction in mortality as the main end-point.
在2年的时间里,61例患有静脉曲张但既往未出血的肝硬化患者入住我院。其中50例为酒精性肝硬化。11例患者的Child-Turcotte-Pugh分级为A,30例为B,20例为C。静脉曲张为F1级的有18例,F2-F3级的有43例。在长达40个月的随访期间,1例患者失访,22例患者死亡,7例死于胃肠道出血,15例死于肝功能衰竭。任何原因导致的死亡概率与Child-Turcotte-Pugh分级、腹水、肝性脑病、血清白蛋白、血清胆红素、凝血酶原指数和半乳糖清除能力显著相关。根据Cox模型,独立的预后变量为血清白蛋白、血清胆红素、肝性脑病和静脉曲张。仅考虑死于肝功能衰竭的患者,生存率与相同的决定因素单因素相关,而Cox模型确定血清胆红素、血清白蛋白、腹水和半乳糖清除能力为独立的预后指标。仅考虑死于胃肠道出血的患者,由于死亡人数较少,无法进行Cox模型分析。在F1级静脉曲张患者中,死于肝功能衰竭的概率比死于胃肠道出血的概率高5倍;在F2-F3级静脉曲张患者中,肝功能衰竭和胃肠道出血导致的死亡各占约一半。这些数据在规划以降低死亡率为主要终点的预防临床试验时可能会有用。
