METHODS： A total of 137 consecutive patients with CriB who underwent percutaneous liver biopsy were retrospectively analyzed. These patients were divided into two groups according to their aminotransferase （ALT） level. The sensitivity, specificity, positive predictive value （PPV）, negative predictive value （NPV）, the likelihood ratio （LR） of aminotransferase/platelet ratio index （APRI） ≥ 1.5 or 〈 1.5 in combination with different hyaluronic acid （HA） cut-off points were calculated for the presence of moderate to severe fibrosis/cirrhosis （fibrosis stages 2 and 4） and no to mild fibrosis/cirrhosis （fibrosis stages 0 and 1）. RESULTS： The APRI correlated with fibrosis stage in CriB patients. The APRI ≥1.5 in combination with a cut-off HA cut-off point 〉 300 ng/mL could detect moderate to severe fibrosis （stages 2-4） in Crib patients. The PPV was 93.7%, the specificity was 98.9%. The APRI 〈 1.5 in combination with different HA cut-off points could not detect no to mild fibrosis in CHB patients. CONCLUSION： The APRI ≥ 1.5 in combination with a HA cut-off point 〉 300 ng/mL can detect moderate to severe fibrosis （stages 2-4） in Crib patients.展开更多

METHODS: In this prospective study, 206 patients had CHB with liver fibrosis stages F0-F4 classified by METAVIR and 40 were healthy volunteers were measured by ARFI, APRI and Forns index separately or combined as indicated. RESULTS: ARFI, APRI or Forns index demonstrated a significant correlation with the histological stage(all P < 0.001). According to the AUROC of ARFI and APRI for evaluating fibrotic stages more than F2, ARFI showed an enhanced diagnostic accuracy than APRI(P < 0.05). The combined measurement of ARFI and APRI exhibited better accuracy than ARFI alone when evaluating ≥ F2 fibrotic stage(Z = 2.77, P = 0.006). Combination of ARFI, APRI and Forns index did not obviously improve the diagnostic accuracy compared to the combination of ARFI and APRI(Z = 0.958, P = 0.338). CONCLUSION: ARFI + APRI showed enhanced diagnostic accuracy than ARFI or APRI alone for significant liver fibrosis and ARFI + APRI + Forns index shows the same effect with ARFI + APRI.展开更多

The hazard ratio(HR) of HCC with different risk factors was determined by Cox proportional hazards model. RESULTS One hundred and forty-four PBC patients were recru-ited. Patients were diagnosed at a median age of 57.8 years [interquartile range(IQR): 48.7-71.5 years), and 41(28.5%) patients had cirrhosis at baseline. The median follow-up duration was 6.9 years(range: 1.0-26.3 years). Twelve patients developed HCC, with an incidence rate of 10.6 cases per 1000 patient-years. The overall 5-, 10-and 15-year cumulative incidences of HCC were 2.3% 95%CI: 0%-4.8%), 8.4%(95%CI: 1.8%-14.5%) and 21.6%(6.8%-34.1%), respectively. Older age(HR = 1.07), cirrhosis(HR = 4.38) and APRI at 1 year after treatment(APRI-r1) > 0.54(HR = 3.94) were independent factors for HCC development. APRI-r1, when combined with treatment response, further stratified HCC risk(log rank P < 0.05). The area under receiver operating curve of APRI-r1 in predicting HCC was 0.77(95%CI: 0.64-0.88).CONCLUSION APRI-r1 can be used to predict the development of HCC in PBC patients. Combination of APRI-r1 with treatment response can further stratify the HCC risk.展开更多

All the patients received a percutaneous liver biopsy guided by ultrasonography. LSM, biochemical tests, and complete blood cell counts were performed.RESULTS The pathological examination revealed moderate inflammatory necrosis ratios of 16.81%(16/95), 32.56%(28/86), and 45.31%(28/64), and moderate liverfibrosis of 24.2%(23/95), 33.72%(29/86), and 43.75%(28/64) in the PNALT, PIALT1, and PIALT2 groups, respectively. The degrees of inflammation and liver fibrosis were significantly higher in the PIALT groups than in the PNALT group(P < 0.05). No significant difference was found in the areas under the curve(AUCs) between APRI and FIB-4 in the PNALT group; however, significant differences were found between APRI and LSM, and between FIB-4 and LSM in the PNALT group(P < 0.05 for both). In the PIALT1 and PIALT2 groups, no significant difference(P > 0.05) was found in AUCs for all comparisons(P > 0.05 for all). In the overall patients, a significant difference in the AUCs was found only between LSM and APRI(P < 0.05).CONCLUSION APRI and FIB-4 are not the ideal noninvasive hepatic fibrosis markers for PNALT patients. LSM is superior to APRI and FIB-4 in PNALT patients because of the influence of liver inflammation and necrosis.展开更多

文摘目的研究术前血小板分布宽度(Platelet volume distribution width,PDW)联合系统性炎症指数(Systemic inflammation response index,SIRI)对结肠癌术后复发转移的预测价值。方法以2020年1月-2021年6月江苏大学附属医院胃肠外科就诊并接受根治性切除手术治疗的194例结肠癌患者为结肠癌组,选择同期在本院体检中心招募的100例健康体检者为对照组。术前检测并记录PDW和SIRI,收集患者的一般资料包括:性别、年龄、身高、体重、家族肿瘤史、是否吸烟、酗酒、体质指数(Body mass index,BMI)、肿瘤最大径、TNM分期(Tumor node metastasis,TNM)和分化程度。对患者随访2年,记录结肠癌复发转移情况。采用ROC曲线确定相关变量的临界最佳值,通过AUC(ROC曲线下面积)评价其预后的准确性。结果与对照组比较,结肠癌组PDW和SIRI均显著增高,差异有统计学意义(P<0.05)。术后发生复发转移患者术前PDW与SIRI高于术后未发生复发转移的患者,差异有统计学意义(P<0.05)。TNM分期Ⅲ~Ⅳ期和中低分化程度术后复发转移患者的PDW高于Ⅰ~Ⅱ期患者和高分化程度患者,差异有统计学意义(P<0.05)。肿瘤最大径≥5 cm、TNM分期Ⅲ~Ⅳ期和中低分化程度术后复发转移患者的PDW高于肿瘤最大径<5 cm、TNM分期Ⅰ~Ⅱ期和高分化程度的患者,差异有统计学意义(P<0.05)。PDW、SIRI及两者联合预测结肠癌术后复发转移的曲线下面积(Area under curve,AUC)分别为0.761(95%CI:0.691~0.831),0.836(95%CI:0.775~0.897)和0.918(95%CI:0.876~0.960)。术后复发转移患者的PDW与SIRI呈显著正相关关系(r=0.574,P=0.003)。结论PDW、SIRI与结肠癌患者临床病理特征和术后复发转移有关,两者联合预测术后复发转移的效能较好,可为临床应用提供一定参考价值。
