降钙素原对肝硬化并发自发性腹膜炎的诊断价值

目的：探讨降钙素原水平在诊断肝硬化并发自发性腹膜炎中的价值。方法收集2010年1月～2014年5月在北京大学首钢医院诊断的96例肝硬化腹水患者的临床和实验室检查资料，分析血清和腹水钙素原水平与自发性腹膜炎的相关性。结果31例自发性腹膜炎患者的血清和腹水降钙素原水平均明显高于65例无自发性腹膜炎患者，差异有统计学意义（P〈0.05）；血清和腹水降钙素原诊断自发性腹膜炎的灵敏度分别为90.3%和96.8%。结论血清和腹水降钙素原水平对肝硬化并发自发性腹膜炎具有良好的诊断价值。

The value of procalcitonin levels in diagnosis of spontaneous bacterial peritonitis with liver cirrhosis

Objective To explore the clinical value of procalcitonin （PCT） levels in diagnosis of spontaneous bacterial peritonitis （SBP） with liver cirrhosis. Methods From January 2010 to May 2014,96 cases of patients with liver cirrhosis and ascites were diagnosed in Peking University Shougang Hospital.The clinical and laboratorial data of these patients were collected retrospectively.The correlation between PCT levels and SBP was analyzed. Results The serum and ascetic PCT levels were significantly higher in SBP group （n=31） than those of non-SBP group （n=65）,the differences were significant （P〈0.05）.The sensitivity of serum and ascetic PCT level in diagnosis of SBP was 90.3% and 96.8%,respectively. Conclusion The PCT level can be used as one of the effective diagnosis index for SBP with liver cirrhosis.
