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

METHODS: A total of 137 consecutive patients with CHB 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 CHB 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 CHB 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 >300ng/mL can detect moderate to severe fibrosis (stages 2-4) in CHB patients.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

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
