The value of platelet count in evaluating the degree of liver fibrosis in patients with chronic hepatitis B

Staging liver fibrosis and cirrhosis using non-invasive tests in people with chronic hepatitis B to inform WHO 2024 guidelines: a systematic review and meta-analysis

BACKGROUND

Non-invasive tests (aspartate aminotransferase-to-platelet ratio index [APRI] and transient elastography [FibroScan]) were recommended in the 2015 WHO guidelines to guide treatment decisions in people with chronic hepatitis B. We updated the systematic review and meta-analysis that informed the 2015 guidelines to inform new cutoffs for non-invasive tests for the diagnosis of significant fibrosis and cirrhosis for the 2024 WHO guidelines for chronic hepatitis B.

METHODS

We searched PubMed (MEDLINE), Embase, and Science Citation Index Expanded (Web of Science) for studies published in any language between Jan 1, 2014, and Feb 15, 2023. We included all studies that reported cross-sectional data on the staging of fibrosis or cirrhosis with APRI, Fibrosis-4 (FIB-4), and FibroScan compared with liver biopsy as the reference standard in people with chronic hepatitis B. We excluded studies in which the maximum interval between liver biopsy and non-invasive fibrosis test was more than 6 months; that reported on fewer than ten patients with advanced fibrosis or cirrhosis; that were done exclusively in children; and did not report diagnostic accuracy across our prespecified ranges of test cutoffs. The results of this updated search were collated with the meta-analysis that informed the 2015 guidelines. Outcomes of interest were the sensitivity and specificity of non-invasive tests using defined index test cutoffs for detecting significant fibrosis (≥F2), advanced fibrosis (≥F3), and cirrhosis (F4) based on the METAVIR staging system. We performed meta-analyses using a bivariate random-effects model.

FINDINGS

Of 19 933 records identified by our search strategy, 195 were eligible for our systematic review and combined with the 69 studies from the previous meta-analysis to total 264. Two studies were at low risk of bias, 31 studies had unclear risk of bias, and 231 studies had a high risk of bias. Of these 264, 211 studies with 61 665 patients were used in the meta-analysis. For the diagnosis of significant fibrosis (≥F2), sensitivity and specificity were 72·9% (95% CI 70·2-75·5) and 64·7% (95% CI 61·0-68·2) for the APRI low cutoff (>0·3 to 0·7), 30·5% (23·7-38·3) and 92·3% (89·3-94·6) for the APRI high cutoff (>1·3 to 1·7), and 75·1% (72·2-77·7) and 79·3% (76·2-82·2) for FibroScan (>6·0 to 8·0 kPa), respectively. For the diagnosis of cirrhosis (F4), sensitivity and specificity were 59·4% (53·2-65·2) and 73·9% (70·1-77·4) for the APRI low cutoff (>0·8 to 1·2), 30·2% (24·2-36·9) and 88·2% (85·4-90·6) for the APRI high cutoff (>1·8 to 2·2), and 82·6% (77·8-86·5) and 89·0% (86·3-91·2) for FibroScan (>11·0 to 14·0 kPa), respectively. Using a hypothetical population of 1000 unselected patients with chronic hepatitis B with a 25% prevalence of significant fibrosis (≥F2), the APRI low cutoff for significant fibrosis (≥F2) would result in 262 (26·2%) false positives but only 68 (6·8%) false negatives. The FibroScan cutoff would result in 158 (15·8%) false positives and 63 (6·3%) false negatives. In a population with a 5% prevalence of cirrhosis (F4), the APRI low cutoff for cirrhosis (F4) would result in 247 (24·7%) false positives and 21 (2·1%) false negatives and the FibroScan cutoff would result in 105 (10·5%) false positives and nine (0·9%) false negatives.

INTERPRETATION

These findings have informed new thresholds of APRI and FibroScan for diagnosis of significant fibrosis and cirrhosis in the 2024 WHO guidelines on chronic hepatitis B, with an APRI score greater than 0·5 or a FibroScan value greater than 7·0 kPa considered to identify most adults with significant fibrosis (≥F2) and an APRI score greater than 1·0 or a FibroScan value greater than 12·5 kPa to identify most adults with cirrhosis (F4). These patients are a priority for antiviral treatment.

Predictors of liver fibrosis progression in cohort of type 2 diabetes mellitus patients with MASLD

AIM

To investigate predictors of liver fibrosis progression in patients with type 2 diabetes mellitus (T2DM) over a minimum follow-up duration of three years.

METHODS

Two hundred and thirty-three patients completed the follow-up period and their clinical, laboratory and liver FibroScan data are reported. Patients were categorized into progressors 42 (18.0 %) and non-progressors 191 (82.0 %) based on liver fibrosis progression. Factors influencing fibrosis progression were identified by comparing these groups.

RESULTS

Progressors showed significantly increased aspartate aminotransferase (AST) (p = 0.010), increased alkaline phosphatase (ALP) (p = 0.001) and decreased platelet count (p = 0.002). Non-progressors exhibited significant decreases in diastolic blood pressure (DBP) (p = 0.050), body mass index (BMI) (p < 0.001), waist circumference (p < 0.001), gamma-glutamyl transferase (GGT) (p < 0.001), albumin (p < 0.001), alanine aminotransferase (ALT) (p = 0.022), glycosylated haemoglobin (HbA1c) (p = 0.002) and fasting blood sugar (FBS) (p = 0.030) with increase in HDL-cholesterol (p < 0.001), creatinine (p < 0.001), bilirubin (p < 0.001), and ALP (p = 0.007). Baseline parameters predictive of liver fibrosis progression included elevated AST and reduced platelet count. Delta changes from baseline to follow-up revealed that increases in ALP, BMI, waist circumference, and reduction in platelet count were correlated with fibrosis progression. Use of GLP-1 receptor agonist was associated with reduced progression.

CONCLUSION

In conclusion, increase in ALP and waist circumference and reduction in platelet count are predictive of liver fibrosis progression in patients with T2DM. GLP-1 receptor agonists use seems to have a promising protective effect against liver fibrosis progression.

A nomogram model for predicting advanced liver fibrosis in patients with hepatitis B: A multicenter study

BACKGROUND

Biopsy is the gold standard method for diagnosing liver fibrosis. FibroScan is a non-invasive method of diagnosing liver fibrosis, but it still faces some limitations. This study aimed to establish a nomogram model and identify patients at high risk of advanced liver fibrosis associated with hepatitis B infection.

METHODS

Data were collected from 375 patients with hepatitis B who underwent liver biopsy. Patients were divided randomly into the training (n = 263) and validation sets (n = 112). Their demographic and clinical characteristics were analyzed using the least absolute shrinkage and selection operator regression (LASSO). A nomogram model was established to predict the fibrosis stage, and its performance was assessed using the area under the receiver operating characteristic curve (AUC), calibration curve, and decision curve analysis (DCA) and was compared with other recognized models.

RESULTS

In total, 209 patients with non-advanced fibrosis (S0-1) and 166 patients with advanced fibrosis (S ≥ 2) were included. Hyaluronic acid (HA), laminin, total cholesterol (TC), platelet, and age were entered into the nomogram model based on the LASSO analysis. The nomogram model for predicting advanced fibrosis exhibited a relatively high AUC in the training set. Compared with FIB4 and APRI, the nomogram model showed a better agreement between the actual status and predicted status based on the calibration curve. The nomogram model showed an AUC similar to FibroScan in the validation cohort, and showed high clinical net benefits in the training and validation sets.

CONCLUSION

Our nomogram model can help identify patients with hepatitis B and advanced liver fibrosis.

Accuracy of blood-based biomarkers for staging liver fibrosis in chronic liver disease: A systematic review supporting the AASLD Practice Guideline

BACKGROUND AND AIMS

Blood-based biomarkers have been proposed as an alternative to liver biopsy for noninvasive liver disease assessment in chronic liver disease. Our aims for this systematic review were to evaluate the diagnostic utility of selected blood-based tests either alone, or in combination, for identifying significant fibrosis (F2-4), advanced fibrosis (F3-4), and cirrhosis (F4), as compared to biopsy in chronic liver disease.

APPROACH AND RESULTS

We included a comprehensive search of databases including Ovid MEDLINE(R), EMBASE, Cochrane Database, and Scopus through to April 2022. Two independent reviewers selected 286 studies with 103,162 patients. The most frequently identified studies included the simple aspartate aminotransferase-to-platelet ratio index and fibrosis (FIB)-4 markers (with low-to-moderate risk of bias) in HBV and HCV, HIV-HCV/HBV coinfection, and NAFLD. Positive (LR+) and negative (LR-) likelihood ratios across direct and indirect biomarker tests for HCV and HBV for F2-4, F3-4, or F4 were 1.66-6.25 and 0.23-0.80, 1.89-5.24 and 0.12-0.64, and 1.32-7.15 and 0.15-0.86, respectively; LR+ and LR- for NAFLD F2-4, F3-4, and F4 were 2.65-3.37 and 0.37-0.39, 2.25-6.76 and 0.07-0.87, and 3.90 and 0.15, respectively. Overall, the proportional odds ratio indicated FIB-4 <1.45 was better than aspartate aminotransferase-to-platelet ratio index <0.5 for F2-4. FIB-4 >3.25 was also better than aspartate aminotransferase-to-platelet ratio index >1.5 for F3-4 and F4. There was limited data for combined tests.

CONCLUSIONS

Blood-based biomarkers are associated with small-to-moderate change in pretest probability for diagnosing F2-4, F3-4, and F4 in viral hepatitis, HIV-HCV coinfection, and NAFLD, with limited comparative or combination studies for other chronic liver diseases.

Correlation Between Real-Time Shear Wave Elastography and Liver Serum Markers in Determining the Stage of Liver Fibrosis in Patients with Chronic Liver Diseases

Introduction: Non-invasive methods aim to predict the stage of liver fibrosis in line with histological findings via biopsy. Shear wave elastography and serum markers are proven as accurate non-invasive methods for determining liver fibrosis as a modern non-invasive methods compared to liver biopsy in staging hepatic fibrosis. Aims: This study aims to determine the correlation between Shear Wave Elastography and indirect and direct serum markers of fibrosis when staging liver fibrosis. Material and methods: The study was conducted in the Clinic of Gastroenterohepatology, the Institute of Immunology and Human Genetics, and the Institute of Pathology between 2021 and 2023. The study comprises 70 patients with liver lesions, diagnosed based on clinical results, laboratory tests, and ultra-sound imaging. All patients underwent liver biopsy, classified according to Ishak and Metavir score as a reference method for diagnosing liver fibrosis. Real-time shear wave elastography was also performed as a non-invasive method and serum markers were checked for liver fibrosis. Findings: The statistical analysis indicated a positive correlation between the values of direct and indirect liver fibrosis markers and Shear Wave Elastography results. Conclusion: Our study has demonstrated that shear wave elastography has a significant positive correlation with biochemical markers of liver lesions and serum markers of liver fibrosis, whereas it has a negative correlation with platelets.

Correlation Between Thrombin Generation and Hepatic Fibrosis in Chronic Liver Diseases

Hepatic stellate cells (HSC) are recruited to the site of injury in the liver tissue repair mechanism, and the changes HSC undergo reflect paracrine stimulation by all cell types (sinusoidal endothelial cells, Kupffer cells, hepatocytes, platelets, and leukocytes). This study aimed to analyse a possible correlation between the degree of liver fibrosis and thrombin generation in patients with chronic liver diseases. Background Coagulation disorders in patients with chronic liver disease continue to challenge clinicians. A more accurate assessment of the coagulation cascade is provided by investigating thrombin production in individuals with chronic liver disease with varying degrees of fibrosis. Methods This prospective observational pilot study was done on hospitalized patients with chronic liver diseases. Thrombin generation from their platelet-poor plasma was studied and the degree of liver fibrosis assessed by transient elastography versus that of control subjects. Results The peak thrombin is significantly higher in those with severe liver stiffness (F3) than in those with more advanced fibrosis/liver cirrhosis (F4). Also, the total concentration of thrombin formed in the time interval (area under the curve (AUC)) and velocity index (VI) is higher in those with F3 than those with F4. Conclusion Thrombin generation decreases with the progression of liver fibrosis.

Associated Factors for Liver Fibrosis and Histological Activity Index in Treatment-Naïve HBeAg-Positive Chronic Hepatitis B Infection: Insights from a Retrospective Analysis

Objective

The study aimed to identify predictors of advanced fibrosis score and histological activity index (HAI) in HBeAg-positive patients to facilitate early disease detection and reduce the need for invasive biopsies.

Materials and Methods

The single-center retrospective study included treatment-naïve HBeAg-positive chronic hepatitis B (CHB) patients. Patients with HAI ≥6 and/or fibrosis ≥2 were considered to have significant liver damage. Independent determinants were identified by univariate and multivariate logistic regression analysis. Cut-off values for variables were determined by receiver operating characteristics (ROCs) curve analysis.

Results

The study enrolled a cohort of 66 patients, with 51.5% male and a median age of 26 (22.7-34.2) years. In assessing necroinflammation, no significant differences were observed in age and gender between patients with HAI <6 and HAI ≥6. However, patients with HAI ≥6 exhibited higher aspartate aminotransferase (AST) levels compared to those with HAI <6. Furthermore, lower albumin levels and platelet (PLT) counts, along with higher fibrosis-4 (FIB-4) scores, were associated with HAI ≥6. In the evaluation of fibrosis, while gender distribution did not differ significantly, patients with fibrosis grade ≥2 were older and had higher HAI scores, HAI ≥6 ratios, and FIB-4 scores compared to those with fibrosis grade <2. Multivariate analysis identified albumin as a significant predictor for both HAI ≥6 and fibrosis grade ≥2. The area under ROC (AUROC) values of albumin for predicting HAI ≥6 and fibrosis ≥2 were 0.696 and 0.698, respectively, indicating moderate predictive ability.

Conclusion

Albumin was found to be an independent predictor of liver damage in HBeAg-positive CHB patients. The fact that the optimal threshold values detected for both HAI ≥6 and fibrosis ≥2 in this patient group were close to normal values suggests that clinicians should be more cautious in monitoring albumin levels and other pre-defined parameters to avoid delays in diagnosis.

Macrophage-2-Binding Protein Glycosylation Isomer (M2BPGi) and AGAP Score as Markers of Noninvasive Test for Liver Fibrosis versus FibroScan in Chronic Hepatitis B Patients: A Retrospective Observational Study

Background

Liver biopsy as the gold standard for assessing the degree and diagnosis of fibrosis still has significant drawbacks, which make the emergence of a much less invasive diagnostic marker possible. M2BPGi levels and the AGAP score, the two newest serological markers, are known to have good sensitivity for detecting liver fibrosis. This study is aimed at determining the validity of examining M2BPGi levels and AGAP scores on the Fibroscan examination as markers of noninvasive test for liver fibrosis in chronic hepatitis B patients.

Methods

This is an observational, descriptive study with a retrospective design. This study used secondary data taken from medical records and blood specimen research materials of outpatients at the Hepatology Gastroenterology Polyclinic at a tertiary general hospital in West Java, Indonesia, with a diagnosis of chronic hepatitis B.

Results

There were 109 research subjects included. There were 73 (66.9%) subjects with no- or low-grade fibrosis and 36 (33.1%) with advanced fibrosis. The sensitivity and specificity of the M2BPGi were 88.9% and 61.6% (PPV 55.3%; NPV 91.8%; AUC 0.753), while the AGAP score was 47.2% and 100% (PPV 100%; NPV 79.3%; AUC 0.736). The combined M2BPGi level and the AGAP score showed a sensitivity of 80.9% and a specificity of 100% (PPV 100%; NPV 91.8%; AUC 0.905).

Conclusion

The AGAP score and M2BPGi levels together are a better way to measure the degree of liver fibrosis in people with chronic hepatitis B than either M2BPGi or the AGAP score alone.

Daily Aspirin Reduced the Incidence of Hepatocellular Carcinoma and Overall Mortality in Patients with Cirrhosis

BACKGROUND

Cirrhosis is the primary risk factor for hepatocellular carcinoma (HCC) and gastrointestinal bleeding (GI). We aimed to assess the efficacy and safety of daily aspirin on HCC occurrence, overall survival, and GI bleeding in cirrhotic patients.

METHODS

A total of 35,898 eligible cases were enrolled for analyses from an initial 40,603 cirrhotic patients without tumor history. Patients continuously treated with aspirin for at least 84 days were in the therapy group, whereas those without treatment were controls. A 1:2 propensity score matching by age, sex, comorbidities, drugs, and significant clinical laboratory tests with covariate assessment was used.

RESULTS

Multivariable regression analyses revealed that daily aspirin use was independently associated with a reduced risk of HCC (three-year HR 0.57; 95% CI 0.37-0.87; p = 0.0091; five-year HR 0.63, 95% CI 0.45-0.88; p = 0.0072) inversely correlated with the treatment duration [3-12 months: HR 0.88 (95% CI 0.58-1.34); 12-36 months: HR 0.56 (0.31-0.99); and ≥ 36 months: HR 0.37 (0.18-0.76)]. Overall mortality rates were significantly lower among aspirin users compared with untreated controls [three-year HR 0.43 (0.33-0.57); five-year HR 0.51 (0.42-0.63)]. Consistent results were obtained when the laboratory data were included in the propensity score for matching.

CONCLUSIONS

Long-term aspirin use significantly reduced the incidence of HCC and overall mortality without increasing gastrointestinal bleeding in cirrhotic patients.

The Important Roles of Natural Killer Cells in Liver Fibrosis

Liver fibrosis accompanies the development of various chronic liver diseases and promotes their progression. It is characterized by the abnormal accumulation of extracellular matrix proteins (ECM) and impaired ECM degradation. Activated hepatic stellate cells (HSCs) are the major cellular source of ECM-producing myofibroblasts. If liver fibrosis is uncontrolled, it may lead to cirrhosis and even liver cancer, primarily hepatocellular carcinoma (HCC). Natural killer (NK) cells are a key component of innate immunity and have miscellaneous roles in liver health and disease. Accumulating evidence shows that NK cells play dual roles in the development and progression of liver fibrosis, including profibrotic and anti-fibrotic functions. Regulating NK cells can suppress the activation of HSCs and improve their cytotoxicity against activated HSCs or myofibroblasts to reverse liver fibrosis. Cells such as regulatory T cells (Tregs) and molecules such as prostaglandin E receptor 3 (EP3) can regulate the cytotoxic function of NK cells. In addition, treatments such as alcohol dehydrogenase 3 (ADH3) inhibitors, microRNAs, natural killer group 2, member D (NKG2D) activators, and natural products can enhance NK cell function to inhibit liver fibrosis. In this review, we summarized the cellular and molecular factors that affect the interaction of NK cells with HSCs, as well as the treatments that regulate NK cell function against liver fibrosis. Despite a lot of information about NK cells and their interaction with HSCs, our current knowledge is still insufficient to explain the complex crosstalk between these cells and hepatocytes, liver sinusoidal endothelial cells, Kupffer cells, B cells, and T cells, as well as thrombocytes, regarding the development and progression of liver fibrosis.

Understanding the Potential Role of Nanotechnology in Liver Fibrosis: A Paradigm in Therapeutics

The liver is a vital organ that plays a crucial role in the physiological operation of the human body. The liver controls the body's detoxification processes as well as the storage and breakdown of red blood cells, plasma protein and hormone production, and red blood cell destruction; therefore, it is vulnerable to their harmful effects, making it more prone to illness. The most frequent complications of chronic liver conditions include cirrhosis, fatty liver, liver fibrosis, hepatitis, and illnesses brought on by alcohol and drugs. Hepatic fibrosis involves the activation of hepatic stellate cells to cause persistent liver damage through the accumulation of cytosolic matrix proteins. The purpose of this review is to educate a concise discussion of the epidemiology of chronic liver disease, the pathogenesis and pathophysiology of liver fibrosis, the symptoms of liver fibrosis progression and regression, the clinical evaluation of liver fibrosis and the research into nanotechnology-based synthetic and herbal treatments for the liver fibrosis is summarized in this article. The herbal remedies summarized in this review article include epigallocathechin-3-gallate, silymarin, oxymatrine, curcumin, tetrandrine, glycyrrhetinic acid, salvianolic acid, plumbagin, Scutellaria baicalnsis Georgi, astragalosides, hawthorn extract, and andrographolides.

Predictors of eligibility for reimbursement of antiviral treatment in HBe-Ag negative chronic hepatitis B patients with high ALT levels

Background/Aim: A liver biopsy is required for the reimbursement of antiviral therapy in Hepatitis B e-antigen (HBe-Ag) negative chronic hepatitis B patients. Liver biopsy is an invasive procedure with potential complications, such as bleeding, pain, pneumothorax, and even death. The study aimed to evaluate simple and non-invasive parameters that may help predict histological criteria that would be eligible for antiviral treatment reimbursement. Methods: HBeAg-negative chronic hepatitis B patients with alanine transaminase (ALT) levels > upper normal limit (40 IU/L) and HBV DNA viral load > 2000 IU/ml who underwent liver biopsy were enrolled in this retrospective cohort study. ALT, aspartate aminotransferase (AST), alpha-fetoprotein (AFP) values, hepatitis B virus (HBV) DNA levels, platelet count, and hepato-steatosis grade based on ultrasonography were used to predict the eligibility for antiviral therapy reimbursement. Eligibility for reimbursement of antiviral treatment regarding histological criteria defined by National Social Security Institution is based on the hepatitis activity index (HAI) score ≥ 6 and/or fibrosis score ≥ 2 according to Ishak’s scoring system. Results: One hundred and fifteen patients were included in the study; 79 patients (68.7%) were male. The mean age of patients was 46.51 (11.39). Sixty-two patients (53.9%) had a fibrosis score ≥ 2, and 80 (69.6%) patients had an HAI score ≥ 6. Ninety-two (80%) of the patients fulfilled histological criteria for antiviral treatment reimbursement. Multivariate analysis revealed that age and platelet count were independent predictors of eligibility for antiviral treatment reimbursement. The platelet count cut-off point was 198 x 109 /L for predicting eligibility for antiviral treatment reimbursement. Conclusion: Most patients (92/115, 80%) with high ALT and DNA viral load were eligible for antiviral treatment reimbursement. Platelet count and age may be used as simple non-invasive parameters for predicting the eligibility for antiviral treatment reimbursement in terms of histological findings.

Diagnostic accuracy of red blood cell distribution width to platelet ratio for predicting liver fibrosis in patients with chronic hepatitis B: A meta-analysis

OBJECTIVE

This study aims to systematically review the performance of red blood cell distribution width to platelet ratio (RPR) in the diagnosis of significant or advanced fibrosis, and cirrhosis associated with Hepatitis B virus (HBV).

METHODS

The relevant studies were comprehensively searched in English databases such as Web of Science, PubMed, EMBASE, Cochrane Library, as well as Chinese databases such as China National Knowledge Infrastructure, Wanfang Data from the inception to March 2021. Accuracy of RPR in diagnosing significant or advanced fibrosis and liver cirrhosis was assessed by area under the curve (AUC), pooled sensitivity and specificity, as well as positive and negative likelihood ratios. Stata 15.0 software was applied to analyze the data.

RESULTS

In total, 13 literature met the requirements, including patients with significant fibrosis (n=1890), advanced fibrosis (n=645), and cirrhosis (n=499). The prevalence rates of significant fibrosis, advanced fibrosis and cirrhosis were 49.31% (range: 17.25%-84.21%), 37.07% (range: 9.60%-58.20%) and 2.18% (range: 2.78%-44.19%), respectively. The AUCs for predicting significant fibrosis, advanced fibrosis, and cirrhosis by RPR were 0.73 (95%CI: 0.69-0.76),0.80 (95%CI: 0.77-0.84) and 0.80 (95%CI: 0.76-0.83), respectively.

CONCLUSION

RPR is of some diagnostic value to the prediction of HBV-related significant fibrosis, advanced fibrosis and cirrhosis.This conclusion is urgently needed to be verified by further multi-center studies of large sample size and rigorous design.

The value of platelet count in evaluating the degree of liver fibrosis in patients with chronic hepatitis B

Objective

To investigate the value of platelet count in evaluating the degree of liver fibrosis in patients with chronic hepatitis B (CHB).

Methods

A total of 158 CHB patients who underwent liver biopsy in our hospital were included, and the clinical characteristics of these patients were retrospectively analyzed. The diagnostic values of platelet count, aspartate aminotransferase‐to‐platelet ratio index (APRI), and the fibrosis index based on four factors (FIB‐4) for significant fibrosis (F ≥ 2) and early cirrhosis (F = 4) stages in CHB patients were assessed by the use of receiver operating characteristic (ROC) analysis.

Results

The median (F0: 221.0; F1: 210.0; F2: 188.0; F3: 171.0; and F4: 155.5) and mean rank (F0: 120.4; F1: 100.1; F2: 82.2; F3: 67.9; and F4: 49.5) of platelet count decreased along the aggravation of fibrosis (F0‐F4). The areas under the ROC curve for the platelet count in diagnosis of significant fibrosis stage was 0.70, which had no significant difference with FIB‐4 (0.73) and APRI (0.68) in diagnostic efficacy (P = .428). The areas under the ROC curve of platelet count in diagnosis of early cirrhosis were 0.72, which had no significant difference with FIB‐4 (0.76) and APRI (0.68) (P = .094).

Conclusion

The platelet count, as a simple and non‐invasive index, could evaluate the degree of liver fibrosis in CHB individuals. At the same time, the diagnostic efficiency of platelet count to evaluate the significant liver fibrosis and early cirrhosis is comparable to FIB‐4 and APRI.
