Vancomycin hydrochloride (2 g daily) was administered to 12 patients with cirrhosis and lactulose resistant portal systemic encephalopathy in a double blind crossover trial. All 12 patients showed a remarkable clinical improvement after vancomycin treatment. The mean (SE) electroencephalographic (EEG) frequency changed from 6.3 (0.2) to 8.5 (0.2) cps (p less than 0.001) and the mean arterial ammonia concentration from 152 (4) micrograms/ml to 97 (8) micrograms/ml (p less than 0.001). Their clinical condition deteriorated when treatment was switched to lactulose, returning to the previous slower EEG frequency and high arterial ammonia concentrations. Vancomycin seems to be effective in chronic portal systemic encephalopathy in patients who are not helped by lactulose alone.
在一项双盲交叉试验中,对12例患有肝硬化且对乳果糖耐药的门体性脑病患者给予盐酸万古霉素(每日2克)治疗。所有12例患者在万古霉素治疗后均显示出显著的临床改善。平均(标准误)脑电图(EEG)频率从6.3(0.2)次/秒变为8.5(0.2)次/秒(p<0.001),平均动脉血氨浓度从152(4)微克/毫升降至97(8)微克/毫升(p<0.001)。当治疗改为乳果糖时,他们的临床状况恶化,EEG频率恢复到先前较慢的水平,动脉血氨浓度升高。对于仅使用乳果糖无效的患者,万古霉素似乎对慢性门体性脑病有效。
