Influence of CCL20 Overproduction on Patients with HBV Related Acute-on-chronic Liver Failure[J]. Journal of Sun Yat-sen University (Medical Sciences), 2016, 37(5).
【目的】: 探讨乙肝相关慢加急性肝衰竭(HBV-ACLF)患者血清CCL20的表达及其高表达对HBV-ACLF的影响。【方法】 收集30例HBV-ACLF患者外周血,以30例慢性乙型肝炎(CHB)患者和27例健康体检者(NC)作为对照,采用ELISA法检测血清中CCL20的表达,荧光定量PCR法检测HBV-DNA定量,化学发光法检测HBeAg的状态及甲胎蛋白水平,分析CCL20的表达与HBV病毒产物及临床指标的关系。【结果】 与NC组及CHB组相比,HBV-ACLF患者血清CCL20水平明显升高 (P < 0.001)。通过相关分析,发现高表达CCL20与总胆红素成正相关关系(P = 0.048);同时发现高表达CCL20与甲胎蛋白水平成正相关关系(P = 0.021)。低HBV-DNA复制患者其CCL20水平高于HBV-DNA较高复制组(P = 0.044),然而不同HBeAg状态的HBV-ACLF患者其CCL20水平差异无统计学意义。【结论】 CCL20趋化因子参与了HBV-ACLF疾病的发生发展,且CCL20高表达提示患者具有良好肝细胞再生潜力。
【Objective】 To investigate serum CCL20 level and its influence on the patients with HBV related acute -on -chronic liver failure (HBV -ACLF). 【Methods】 Peripheral blood samples were collected from 30 patients with HBV -ACLF, 30 patients with chronic hepatitis B (CHB) and 27 normal controls (NC). Serum CCL20 level was measured using ELISA. HBV -DNA loads were measured by fluorescent PCR. The presence of HBeAg and AFP levels were measured by automated chemiluminescence assay. Serum CCL20 levels in HBV -ACLF patients and their correlations with HBeAg presence, HBV -DNA loads and liver function were analyzed. 【Results】 Serum CCL20 levels were significantly elevated in patients with HBV -ACLF compare with NC subjects and CHB patients (P < 0.001). CCL20 levels were positively correlated with Tbil levels (P = 0.048) and AFP levels (P=0.021). Higher CCL20 levels were found in patients with lower HBV -DNA loads than those with higher HBV -DNA loads (P=0.044). However, no significant differences in CCL20 levels were observed between HBeAg -positive and HBeAg -negative patients with HBV -ACLF.【Conclusion】 CCL20 chemokine may contributed to the mechanism of HBV -ACLF, and overproduction of CCL20 may indicate latent capacity of hepatocyte regenaration.
