肝炎肝硬化患者降钙素原与肝功能的关系

Association between PCT levels and liver function in liver cirrhosis patients

目的 探讨肝炎肝硬化患者降钙素原（PCT）水平与肝功能的关系.方法 用半定量固相免疫测定方法 测定44例肝硬化患者血清PCT水平并检测ALT、AST、TBIL、ALB、CHE、CHOL、PTA等指标,并进行Child-pugh分级.结果 以PCT＞0.5μg/L为阳性阈值,阳性组患者ALT、TBIL明显高于阴性组,CHOL、PTA明显低于阴性组.随着PCT水平的增加,ALT、AST、TBIL水平均逐渐升高,PTA逐渐下降.PCT阳性组以Child-pugh B、C级者为主,而PCT阴性组以Child-pugh B级者为主.患者PCT阳性者淋巴计数较PCT阴性者低.结论 肝功能损伤使得肝硬化患者感染的风险增高,且随着损伤程度的加重,进展为重度感染危险逐渐增加.重视肝功能的保护,结合PCT水平的监测,有助于肝炎肝硬化患者感染的早期发现及控制.

Objective To explore the association between procalcitonin （PCT）levels and liver function in liver cirrhosis patients. Methods Collect serum samples from 44 liver cirrhosis patients, detect the PCT levels by semi-quantitative solid immunoassay, and at the same time, detect the serum levels of ALT, AST, TBIL, ALB, CHE, CHOL, PTA etc, then rate the patients by Child-pugh scoring system into Child-pugh A, B, C. Results set PCT ＞0. 5 μg/L as the positive threshold, significantly the PCT positive patients have higher ALT, TBIL but lower CHOL,PTA compared with the PCT negative patients. With the increasing of PCT levels,the ALT, AST, TBIL levels are gradually increased too, but PTA decreased. We find that the PCT positive patients are mainly Child-pugh B and C patients, and PCT negative patients are mainly Child-pugh C patients. PCT positive patient＇s lymphocyte count are lower than PCT negative patient＇s. Conclusion Liver injury increase the risk of infection in liver cirrhosis patients. As the severity of the injury, the patients are easier to progress into severe infection. Combined with monitoring the PCT levels, pay more attention to protect the liver function will be helpful in early detecting infections and controlling of infection in liver cirrhosis patients.
