The nutritional evaluation included serum prealbumin, albumin, transferrin, body mass index (BMI), mid-arm muscle circumference (MAMC), and grip power. The occurrence of subclinical PSE (SPSE) was defined when N20-N65 inter-peak latencies of median nerve-stimulated somatosensory evoked potentials were >2.5 standard deviations of control means. Blood chemistries were tested within 12h of somatosensory evoked potentials test and nutritional evaluation.RESULTS Twenty-five, 17 and 9 cirrhotic patients were graded as Child-Pugh class A, B, and C, respectively. Twenty-four (47.1%) patients developed SPSE. Cirrhotic patients with SPSE had lower serum albumin (2.8g/dL±0.5g/dL vs 3.1g/dL±0.7g/dL, P<0.001) levels than those without SPSE. Prealbumin (10.6mg/dL±5.7mg/dL vs 12.5mg/dL±5.8mg/dL), transferrin (164mg/dL±46mg/dL vs 178mg/dL±58mg/dL), BMI (23.7kg/m2±2.7kg/m2 vs 25.3kg/m2±3.6kg/m2), MAMC (22.2cm±2.6cm vs 22.7cm±3.5cm), and grip power (26.3kg±6.4kg vs 26.9kg±6.8kg) were not different between cirrhotic patients with and without SPSE. N20-N65 inter-peak latencies were correlated with serum albumin levels (P=0.01) but not with prealbumin, transferrin, BMI, MAMC, or grip power. Serum albumin, prealbumin and transferrin levels were different among cirrhotic patients with Child-Pugh classes A, B, and C (P<0.05). BMI, MAMC, and grip power were not different among Child-Pugh classes A, B and C.CONCLUSION Our data suggest that serum albumin level is a simple test in the evaluation of nutritional status in patients with cirrhosis.展开更多

文摘目的:评价事件相关电位P_(300)和智能精神状态检查(MMSE)诊断轻微型肝性脑病(MHE)的价值.方法:30例肝炎后肝硬化患者进行事件相关电位P_(300)和脑诱发电位检查及MMSE检测,并观察1 a后临床肝性脑病(HE)的出现情况.结果:事件相关电位P_(300)异常21例(70.0%),体感诱发电位(SEP)异常11例(36.7%),MMSE得分<27(提示有认知功能障碍)13例(43.3%),事件相关电位P_(300)和/或MMSE异常22例(73.3%),两者均异常10例(33.3%),追踪观察1 a的23位患者中,17例事件相关电位P_(300)和/或MMSE异常患者出现临床肝性脑病12例,两者均无异常的6例患者中,出现临床肝性脑病1例,两者比较有显著性差异(70.6% vs 16.7%,P<0.05).结论:事件相关电位P_(300)和MMSE可作为判断肝硬化失代偿期是否发生轻微型肝性脑病的一种敏感又可靠的方法.
