摘要:

目的 了解人血清细胞角蛋白18(CK-18)、肝纤维化指标与非酒精性脂肪肝(NAFLD)的相关性。方法 通过B超影像学检查将581例NAFLD患者分为轻度组(218例)、中度组(189例)、重度组(174例),正常对照组186名,采用酶联免疫吸附试验(ELISA)定量测定血清CK-18含量,化学发光法检测血清肝纤维化指标[Ⅲ型前胶原(PCⅢ)、Ⅳ型胶原(CⅣ)、层黏蛋白(LN)、透明质酸(HA)]。结果 轻、中、重度NAFLD组和正常对照组CK-18 水平分别为(9.11±3.26)、(11.75±4.86)、(13.75±5.29)和(3.78±0.92)ng/L,PCⅢ水平分别为(112.55±27.54)、(127.18±30.34)、(133.51±48.85)和(95.95±18.43)μg/L, CⅣ水平分别为(59.60±11.04)、(72.08±17.20)、(85.69±24.20)和(54.00±12.88)μg/L, LN水平分别为(99.78±28.06)、(110.99±24.96)、(133.42±21.15)和(84.44±18.20)μg/L, HA水平分别为(82.17±17.75)、(90.52±19.15)、(121.99±26.65)和(78.35±11.95)μg/L,NAFLD各程度组与正常对照组比较,差异均具有统计学意义(P<0.05或P<0.01)。CK-18、PCⅢ、CⅣ、LN、HA诊断NAFLD的受试者工作特征(ROC)曲线下面积分别0.927、0.771、0.793、0.808和0.717;临界值分别为8.6 ng/L、100.9 μg/L、54.35 μg/L、102.34 μg/L和96.05 μg/L;敏感性和特异性CK-18为0.773和0.990,PCⅢ为0.747和0.770,CⅣ为0.823和0.660,LN为0.663和0.860,HA为0.497和0.950。结论 CK-18、PCⅢ、CⅣ、LN、HA对NAFLD临床诊断具有一定价值,其中CK-18的诊断价值最佳,可作为NAFLD的独立预测因素。

Abstract:

Objective To investigate the significance of the serum cytokeratin 18(CK-18) and liver fibrosis indexes level in non-alcoholic fatty liver disease (NAFLD). Methods A total of 581 NAFLD patients and 186 healthy controls (healthy control group) were enrolled. Ultrasonic inspection was carried out to evaluate in NAFLD patients. Enzyme-linked immunosorbent assay (ELISA) was used to detect serum of CK-18 and chemiluminescence method was used to detect serum of procollagen type Ⅲ(PCⅢ), collagen type Ⅳ (CⅣ), laminin (LN), hyaluronic acid(HA). Results Compared with healthy controls,the light NAFLD、the moderate NAFLD、the severe NAFLD of the CK-18 (ng/L)、PC III(μg/L)、C IV(μg/L)、LN(μg/L)、HA(μg/L)respectively was:9.9±3.89,112.55±27.54,62.6±18.04,99.78±28.06,82.17±17.75;13.29±5,127.18±30.34,68.08±20.12,111.95±24.96,90.52±19.15;15.37±5.98,143.51±48.85,93.35±24.3,133.42±21.15,141.99±26.65;3.88±2.8,95.95±18.43,57±22.81,84.44±18.2,68.35±11.95. CK-18、PC III 、C IV 、LN and HA for the diagnosis of NAFLD area under the ROC curve respectively 0.927,0.771,0.793,0.808,0.717;Tangent point were 8.6,54.35,100.9,102.34,96.05; The sensitivity and specificity of CK -18 0.773 and 0.99,PC III was 0.747 and 0.77,C IV was 0.823 and 0.66,LN was 0.663 and 0.663,HA was 0.497 and 0.95. Conclusions As the degree of the NAFLD is aggravating,the serum of CK-18 、PC III、C IV、LN and HA level also gradually rise,is important for clinical diagnosis and monitoring. So in clinical diagnosis it has a certain value,18 CK - best diagnostic value and can be used as an independent predictor of NAFLD.
