综合预测模型FibroTest对慢性乙型肝炎肝纤维化的诊断价值 总被引:5,自引:0,他引:5
目的探讨综合预测模型FibroTest对慢性乙型肝炎肝纤维化的诊断价值。方法留取2002年8月至2005年12月北京大学第一医院、安阳市第五人民医院和无锡市传染病医院的123例行肝活检的慢性乙型肝炎患者的血清,检测α2-巨球蛋白、结合珠蛋白、载脂蛋白-AⅠ、记录总胆红素和谷氨酰转肽酶的数值,并根据其结果结合患者的年龄和性别计算出FibroTest的数值。根据肝纤维化分期设定3个判定点,分别为显著纤维化(S2~S4期),严重纤维化(S3~S4期)和肝硬化(S4期)。以肝活检病理结果为金标准绘制出FibroTest的受试者工作特征曲线,计算曲线下面积(AUC),并与用天冬氨酸转氨酶-血小板比值指数(APRI)计算出的AUC进行比较,评价其对慢性乙型肝炎肝硬化的诊断价值。结果123例肝活检患者中S0期25例(20.3%);S1期27例(22.0%);S2期31例(25.2%);S3期29例(23.6%);S4期11例(8.9%),即显著纤维化者(S2~S4期)71例(57.7%),严重纤维化者(S3~S4期)40例(32.5%),肝硬化者(S4期)11例(8.9%)。FibroTest对3个判定点的AUC值分别为0.814(95%CI:0.740~0.888,P<0.01),0.824(95%CI:0.749~0.898,P<0.01),0.723(95%CI:0.575~0.870,P=0.015)。而APRI对3种不同程度肝纤维化的AUC值分别为0.715(95%CI:0.625~0.805,P=0.001),0.725(95%CI:0.631~0.818,P=0.002)和0.646(95%CI:0.497~0.795,P>0.05)。结论Fi-broTest可以准确地估计慢性乙型肝炎患者有无显著纤维化,可使45.5%的患者避免进行肝脏活检,并保证87.5%的诊断准确率。 相似文献

The utility of measurement of serum immunoglobulin and complement in chronic hepatitis B (CHB) patients remains controversial. This study aimed to investigate the association of serum immunoglobulin and complement levels and liver fibrosis and inflammation stage in CHB patients. A total of 687 patients with CHB who underwent liver biopsy were enrolled. Serum immunoglobulin and complement were measured before liver biopsy, and liver pathological results were recorded. Associations of serum immunoglobulin and complement levels and liver fibrosis and inflammation stage were analysed. C3, C4, IgG and IgG1 had statistically significant differences among different fibrosis and different inflammation groups. Both C3 and C4 negatively correlated with fibrosis and inflammation stage, but IgG and IgG1 showed opposite results. C3, C4, IgG and IgG1 had statistical significance to predict ≥S2, ≥S3 and S4, and also had statistical significance to predict ≥G2, ≥G3 and G4. The area under curve (AUC) of the combination of C3, C4 and IgG (C3 + C4 + IgG) for predicting ≥S2, ≥S3 and S4 was 0.640 (95% CI: 0.603, 0.676), 0.674 (95% CI: 0.638, 0.709) and 0.744 (95% CI: 0.710, 0.776), respectively. The AUC of C3 + C4 + IgG for predicting ≥G2, ≥G3 and G4 was 0.723 (95% CI: 0.688, 0.756), 0.674 (95% CI: 0.638, 0.709) and 0.771 (95% CI: 0.738, 0.802), respectively. C3, C4, IgG and IgG1 are correlated with liver fibrosis and inflammation stage in CHB patients. C3, C4, IgG and IgG1 have diagnostic value for liver fibrosis and inflammation. C3 + C4 + IgG may improve diagnostic accuracy. 相似文献

慢性乙型肝炎肝纤维化分期与血清肝纤维化标志物的相关性分析 总被引:51,自引:2,他引:49
目的 探讨血清透明质酸、Ⅲ型前胶原、层粘蛋白、Ⅳ型胶原等血清肝纤维化标志物与慢性肝炎肝组织炎症活动度及纤维化程度的相关性。方法 278例慢性肝炎患者经肝脏活栓后常规病理检查,肝活检前同时采血检测血清透明质酸、Ⅲ型前胶原、层粘蛋白、Ⅳ型胶原,结果应用x^2检验及t检验进行统计学处理。结果 肝组织纤维化程度与炎症活动度呈正相关关系,透明质酸可反映中度以上慢性肝炎炎症活动度及纤维化程度,且呈正相关;肝脏存在纤维化时层粘蛋白水平升高,与纤维化程度正相关;Ⅲ型前胶原、Ⅳ型胶原水平升高与炎症活动度有关。结论 血清透明质酸、Ⅲ型前胶原、层粘蛋白、Ⅳ型胶原可不同程度反映肝纤维纤维化程度,可作为血清肝纤维化检测指标,透明质酸更可反映肝硬化发展趋势。 相似文献

The natural history of chronic hepatitis B patients who spontaneously cleared serum HBsAg was investigated. A total of 351 patients with chronic hepatitis B were observed in our hospital for at least 3 yr. Seven of these patients became HBsAg negative during the follow-up period. HBsAg disappeared within 6 mo (range = 11 to 169 days, mean = 70 days) after acute elevation of ALT. ALT levels as high as 500 IU were found in three patients, whereas such elevation was not demonstrated in the other four patients. After the disappearance of HBsAg, ALT levels returned to normal in all patients. With one exception, all patients seroconverted to antibody to HBsAg; however, hepatitis B virus DNA remained detectable in serum using the polymerase chain reaction in five patients. The titer of percent inhibition of antibody to HBcAg gradually decreased to less than 70% when a 1:200 dilution of the serum of six patients was used. Four of the patients had active liver disease develop: two had chronic active hepatitis and two had cirrhosis. Three of these four patients subsequently had hepatocellular carcinoma develop. These findings suggest that patients may suffer complications of chronic hepatitis even after normalization of transaminase activities and after the clearance of HBsAg. Thus hepatitis B virus should be considered as a possible factor associated with hepatocellular carcinoma even in the absence of HBsAg, particularly if serum hepatitis B virus DNA persists. 相似文献

BACKGROUND Transient elastography(FibroScan)is a new and non-invasive test,which has been widely recommended by the guidelines of chronic hepatitis B virus(HBV)management for assessing hepatic fibrosis staging.However,some confounders may affect the diagnostic accuracy of the FibroScan device in fibrosis staging.AIM To evaluate the diagnostic value of the FibroScan device and the effect of hepatic inflammation on the accuracy of FibroScan in assessing the stage of liver fibrosis in patients with HBV infection.METHODS The data of 416 patients with chronic HBV infection who accepted FibroScan,liver biopsy,clinical,and biological examination were collected from two hospitals retrospectively.Receiver operating characteristic(ROC)curves were used to analyze the diagnostic performance of FibroScan for assessing the stage of liver fibrosis.Any discordance in fibrosis staging by FibroScan and pathological scores was statistically analyzed.Logistic regression and ROC analyses were used to analyze the accuracy of FibroScan in assessing the stage of fibrosis in patients with different degrees of liver inflammation.A non-invasive model was constructed to predict the risk of misdiagnosis of fibrosis stage using FibroScan.RESULTS In the overall cohort,the optimal diagnostic values of liver stiffness measurement(LSM)using FibroScan for significant fibrosis(≥F2),severe fibrosis(≥F3),and cirrhosis(F4)were 7.3 kPa[area under the curve(AUC)=0.863],9.7 kPa(AUC=0.911),and 11.3 kPa(AUC=0.918),respectively.The rate of misdiagnosis of fibrosis stage using FibroScan was 34.1%(142/416 patients).The group of patients who showed discordance between fibrosis staging using FibroScan and pathological scores had significantly higher alanine aminotransferase and aspartate aminotransferase levels,and a higher proportion of moderate to severe hepatic inflammation,compared with the group of patients who showed concordance in fibrosis staging between the two methods.Liver inflammation activity over 2(OR=3.53)was an independent risk factor for misdiagnosis of fibrosis stage using FibroScan.Patients with liver inflammation activity≥2 showed higher LSM values using FibroScan and higher rates of misdiagnosis of fibrosis stage,whereas the diagnostic performance of FibroScan for different fibrosis stages was significantly lower than that in patients with inflammation activity<2(all P<0.05).A non-invasive prediction model was established to assess the risk of misdiagnosis of fibrosis stage using FibroScan,and the AUC was 0.701.CONCLUSION Liver inflammation was an independent risk factor affecting the diagnostic accuracy of FibroScan for fibrosis stage.A combination of other related noninvasive factors can predict the risk of misdiagnosis of fibrosis staging using FibroScan. 相似文献
