Acoustic Radiation Force Impulse Elastography with APRI and FIB-4 to Identify Significant Liver Fibrosis in Chronic Hepatitis B Patients

Introduction and aim. In chronic hepatitis B (CHB) patients with equivocal indication for antiviral therapy, therapeutic decision currently depends on histopathology of the liver. We aimed to evaluate if acoustic radiation force impulse (ARFI) in conjunction with aspartate transaminase to platelet ratio index (APRI) and fibrosis-4 (FIB-4) score could replace liver biopsy to indicate treatment for CHB.Material and methods. We prospectively enrolled 101 clinically non-cirrhotic patients whose serum alanine aminotransferase was mildly elevated (1-2 folds above the upper normal limit) despite a high viral load (HBV DNA > 2,000 IU/mL). All participants underwent liver biopsy, and measurement of ARFI, APRI and FIB-4. The ability of the markers to distinguish fibrosis ≥ METAVIR F2 was evaluated.Results. According to histopathology, liver fibrosis was METAVIR F0 in 2 (2.0%), F1 in 43 (42.6%), F2 in 34 (33.7%), F3 in 16 (15.8%), and F4 in 6 (5.9%) patients, and was correlated with ARFI (p = 0.0001), APRI (p = 0.012), and FIB-4 (p = 0.004). The six patients with cirrhosis were included for analysis, and received antiviral therapy. The C statistics of ARFI, APRI, and FIB-4 for fibrosis ≥ F2 were 0.70 (95% confidence interval [CI], 0.59-0.80), 0.62 (95% CI, 0.51-0.73), and 0.64 (0.53-0.75), respectively. The cut-off values for 95% sensitivity and 95% specificity to identify significant fibrosis were 0.97 m/sec and 1.36 m/sec for ARFI, 0.36 and 1.0 for APRI, 0.63 and 2.22 for FIB-4, respectively. Using a combination of these 3 indices, 44 patients (43.6%) could be spared a liver biopsy procedure.Conclusions. A combination of ARFI, APRI, and FIB-4 may spare some CHB patients with equivocal indication for antiviral treatment a liver biopsy.     

Noninvasive serum markers in the diagnosis of structural liver damage in chronic hepatitis C virus infection.

AIM: Several noninvasive markers are being used to assess the structural liver damage in patients with chronic hepatitis C (CHC). We evaluated the capacity of serum hyaluronic acid (HA), aspartate aminotransferase (AST)/ALT ratio, the AST to platelet ratio index (APRI) and gamma-glutamyltransferase (GGT) levels to predict the intensity of hepatic fibrosis in patients with CHC. PATIENTS AND METHODS: In a total of 206 hepatitis C virus RNA-positive biopsied patients, AST, ALT, GGT levels, platelet count and serum HA concentration were determined. The APRI was calculated as the ratio of AST to platelets. RESULTS: HA levels were best correlated with disease stage (r=-0.694; P<0.001). In the diagnosis of significant fibrosis (F2-F4), HA levels [AUC=0.879, 95% CI (0.832-0.927)] and APRI [AUC=0.824 (0.772-0.903)] were the markers with the best diagnostic accuracy. These parameters also best identified the presence of cirrhosis (F4), with an AUC of 0.908 (0.868-0.949) for HA and of 0.837 (0.772-0.903) for APRI. CONCLUSION: Serum HA was the parameter that alone presented the best diagnostic accuracy in the assessment of hepatic fibrosis in CHC. The APRI showed a better diagnostic sensitivity than GGT levels or the AST/ALT ratio. Its simple determination and low cost make this index a valid alternative for the noninvasive staging of CHC.     

Validation and comparison of simple noninvasive models for the prediction of liver fibrosis in chronic hepatitis C

Introduction. Although it is standard procedure in the evaluation of liver diseases, biopsy is an invasive method subject to sampling error and intra or inter-observer variability. Thus, surrogate markers of liver fibrosis have been proposed, with variable availability and accuracy.Aim. Validate and compare the performance of APRI and FIB-4 as predictors of liver fibrosis in HCV patients.Material and methods. Cross-sectional study including patients with HCV-RNA (+) who underwent liver biopsy. Significant fibrosis was defined as METAVIR stage ≥ 2. The diagnostic performance of the models in predicting significant fibrosis were evaluated and compared by ROC curves.Results. The study included 119 patients, mean age 43.7 ± 10.6 years and 62% males. Significant fibrosis was identified in 41 patients. The AUROCs observed were: APRI = 0.793 ± 0.047, FIB-4 = 0.811 ± 0.045 and AST/ALT = 0.661 ± 0.055 (P = 0.054 for APRI vs. AST/ALT, and P = 0.014 for FIB-4 vs. AST/ALT). Considering classic cutoffs, the PPV and NPV for APRI and FIB-4 were, respectively, 77% and 92% and 83% and 81%. Thirteen (19%) patients were misdiagnosed by APRI and 16 (18%) by FIB-4. By restricting the indication of liver biopsy to patients with intermediate values, it could have been correctly avoided in 47% and 63% of the patients with APRI and FIB-4, respectively.Conclusion. The models APRI and FIB-4 were superior to AST/ALT ratio in the diagnosis of significant fibrosis in chronic HCV infection. Even though the overall performance of APRI and FIB-4 was similar, a higher proportion of patients may be correctly classified by FIB-4.

A novel index using routine clinical parameters for predicting significant liver inflammation in chronic hepatitis B

Identifying the degree of liver inflammation is critical for therapeutic judgement of patients with chronic hepatitis B (CHB). However, we lack indexes which can accurately predict significant liver inflammation in patients with CHB. This study aimed to develop a simple predictive index for liver inflammation in CHB using routine clinical parameters. A total of 519 patients with CHB who underwent liver biopsy were enrolled and randomly divided into training (n = 346) and validation cohorts (n = 173). Based on routine clinical parameters, gamma‐glutamyl transpeptidase (GGT; P = 0.031) and platelets (PLT; P < 0.001) were identified as independent predictors of significant inflammation by multivariable analysis in the training cohort. Accordingly, the GGT to PLT ratio (GPR) was developed to amplify the opposing effects for predicting liver inflammation. In the training cohort, the AUCs of GPR in predicting significant inflammation were 0.791 (95% CI: 0.742‐0.839), 0.783 (95% CI: 0.717‐0.849) and 0.791 (95% CI: 0.716‐0.867) in the entire patients with CHB, HBeAg‐positive CHB patients and HBeAg‐negative CHB patients, respectively. The diagnostic performance of GPR for significant inflammation was significantly superior to that of alanine aminotransferase (ALT), aspartate transaminase (AST) and GGT in all patients with CHB and HBeAg‐positive CHB patients, but was comparable with ALT, AST and GGT in HBeAg‐negative CHB patients. In the validation cohort, the diagnostic performance of GPR in assessing significant liver inflammation was also superior to other indexes in all patients with CHB and HBeAg‐positive CHB patients, but was comparable with GGT in HBeAg‐negative CHB patients. Thus, GPR can be a novel and simple index for predicting significant liver inflammation in CHB, especially for HBeAg‐positive CHB.

BackgroundsThe evaluation of liver fibrosis stages is essential for the clinical management of chronic hepatitis B (CHB).AimsTo develop and validate a novel noninvasive index for moderate to severe fibrosis (≥S2) in CHB patients.MethodsA total of 401 CHB patients who underwent liver biopsy were divided into the training (n = 300) and validation (n = 101) cohort. Histological severity was scored using a modified Scheuer system. Clinical and laboratory assessments were collected.ResultsIn the training cohort, PACG, a novel index combining the quantitative hepatitis B core antibody (qAnti-HBc), platelet count (PLT), and albumin globulin ratio (A/G), presented better diagnostic performance (AUROC = 0.814) than that of APRI (0.735, p = 0.007) and FIB-4 (0.749, p = 0.014). In the validation cohort, the AUROC of the PACG, APRI, FIB-4 and Fibroscan were 0.834, 0.806, 0.791 and 0.810, respectively. More importantly, a higher and lower cutoff of PACG for predicting ≥S2 fibrosis or not had a >90% sensitivity and specificity, with a diagnostic accuracy of 85.9%.ConclusionPACG is a promising noninvasive alternative to liver biopsy in CHB patients for the evaluation of moderate to severe fibrosis.     

The gamma‐glutamyl transpeptidase‐to‐albumin ratio predicts significant fibrosis and cirrhosis in chronic hepatitis B patients

Background/Aim Simple, inexpensive and clinically available noninvasive liver fibrosis tests are highly needed. We aimed to develop a novel noninvasive index for predicting significant fibrosis and cirrhosis in chronic hepatitis B (CHB) patients. Methods Using liver histology as gold standard, we developed a novel index to predict significant fibrosis and cirrhosis in CHB patients and then compared the diagnostic accuracy of the novel index, aspartate transaminase‐to‐platelet ratio index (APRI), and fibrosis index based on four factors (FIB‐4) in a training set (606 patients) and a validation set (216 patients) from the same patient catchment area. Results Of 606 CHB patients in the training set, 33.2% had significant fibrosis and 11.4% had cirrhosis. In multivariable analysis, gamma‐glutamyl transpeptidase (GGT) (OR=1.032, p<0.001) and albumin (OR=0.953, p=0.048) were independent predictors of significant fibrosis. Consequently, a GGT‐to‐albumin ratio (GAR) was developed. In the training set, the area under the receiver operating characteristic curve (AUROC) of GAR was significantly higher than that of APRI and FIB‐4 to predict ≥F2 (0.82, 0.70, and 0.68, respectively), ≥F3 (0.86, 0.76, and 0.75, respectively), and F4 (0.88, 0.75, and 0.73, respectively), respectively. In the validation set, the AUROC of GAR was also better than APRI and FIB‐4 for predicting ≥F2 (0.81, 0.63 and 0.61, respectively), ≥F3 (0.88, 0.78, and 0.76, respectively) and F4 (0.92, 0.85, and 0.78, respectively), respectively. Conclusions GAR is a more accurate noninvasive index than APRI and FIB‐4 to stage significant fibrosis and cirrhosis in CHB patients and represents a novel noninvasive alternative to liver biopsy.
