Evaluation of Non-Invasive Markers of Liver Fibrosis in Chronic Hepatitis B Patients in a Sub-Saharan African Setting: Transient Elastography versus APRI, FIB4, GTT/Platelet Scores

Background: Non-invasive markers which use routine laboratory tests are less expensive and highly needed to assess and stage liver fibrosis in chronic hepatitis B patients in Sub-Saharan Africa. We aimed at evaluating liver fibrosis, using the Aspartate aminotransferase to Platelet Ratio Index (APRI), Fibrosis Index Based on 4 factors (FIB4), and Gamma-glutamyl transpeptidase to Platelet Ratio (GPR) in chronic hepatitis B patients with transient elastography as the reference so as to choose an alternative to transient elastography. Method: We carried out a cross-sectional study using the records of patients who attended the Douala General Hospital and Marie O Polyclinic Douala from 2012 to 2017. Non-invasive tests were compared with Transient Elastography. The Spearman coefficient was used to determine correlation. The sensitivity, specificity, positive predictive values and negative predictive values were used to get the optimal cut-off values. The diagnostic accuracy was estimated by calculating the area under the Receiver Operating Characteristic Curve (ROC). P Results: Of the 243 patient records studied, the median age or interquartile range (IQR) was 35 (29 - 42) years with a male predominance of 73.7%. More than 60% of the study population had normal transaminases. Significant fibrosis was found in 88 (36.2%) patients and 32 (13.7%) patients had cirrhosis. APRI had the best cut-off values and highest area under the ROC Curve, for significant fibrosis and cirrhosis with 0.55 (0.823 95% CI [0.769 - 0.869], P Conclusion: APRI, had the best diagnostic properties to detect liver fibrosis and cirrhosis in patients with Chronic Hepatitis B in Douala. The cut-off values are 0.55 and 0.65 for significant fibrosis and cirrhosis respectively.

Changing liver stiffness predict regression in advanced fibrosis patients with chronic hepatitis B,but not in moderate fibrosis patients

Background and objective:Liver stiffness measurement(LSM)may effectively correlate to the presence of liver fibrosis,but it is controversial to use for the prediction of clinical outcomes.Therefore,we aimed to evaluate the predictive value of liver stiffness for the regression of liver fibrosis.Methods:In this study,we collected data from a clinical cohort of patients who are received anti-virus therapies for 48 weeks.180 naive chronic hepatitis B(CHB)patients,who received paired LSM and liver biopsy with pre-and post-treatments were analyzed.Two methods(FibroScan and iLivTouch)test LSM.Result:The area under the receiver operating characteristics curve(AUROC)of changing LSM for fibrosis regression is higher in advanced fibrosis patients(F5/6)than in moderate fibrosis patients(F3/4)in both FibroScan(0.719,95%CI,0.590–0.848;P=0.003;vs 0.617,95%CI,0.379–0.856,P=0.282)and iLivTouch(0.707,95%CI,0.567–0.847;P=0.011;vs 0.583,95%CI,0.422–0.744;P=0.377).A higher kappa value was received in advanced stage than in moderate stage both in FibroScan(0.392,P=0.001 vs 0.265,P=0.053)and iLivTouch(0.326,P=0.019 vs 0.030,P=0.833).Cut-off set as 4.10 kPa(sen,69.4%;spe,73.9%)in FibroScan,as 4.25 kPa(sen,56.8%;spe,72.2%)in iLivTouch.Conclusion:The changing LSM can be used for predicting the liver fibrosis regression in advanced stage of CHB patients.

Better performance of PIVKA-II for detecting hepatocellular carcinoma in patients with chronic liver disease with normal total bilirubin

BACKGROUND Serum protein induced by vitamin K absence or antagonist-Ⅱ(PIVKA-Ⅱ) is a promising biomarker for hepatocellular carcinoma(HCC) surveillance.AIM To identify the contributing factors related to the abnormal elevation of PIVKA-Ⅱ level and assess their potential influence on the performance of PIVKA-Ⅱ in detecting HCC.METHODS This study retrospectively enrolled in 784 chronic liver disease(CLD) patients and 267 HCC patients in Mengchao Hepatobiliary Hospital of Fujian Medical University from April 2016 to December 2019. Logistic regression and the area under the receiver operating characteristic curve(AUC) were used to evaluate the influencing factors and diagnostic performance of PIVKA-Ⅱ for HCC, respectively.RESULTS Elevated PIVKA-Ⅱ levels were independently positively associated with alcohol-related liver disease, serum alkaline phosphatase(ALP), and total bilirubin(TBIL) for CLD patients and aspartate aminotransferase(AST) and tumor size for HCC patients(all P < 0.05). Serum PIVKA-Ⅱ were significantly lower in patients with viral etiology, ALP ≤ 1 × upper limit of normal(ULN), TBIL ≤ 1 × ULN, and AST ≤ 1 × ULN than in those with nonviral disease and abnormal ALP, TBIL, or AST(all P < 0.05), but the differences disappeared in patients with early-stage HCC. For patients with TBIL ≤ 1 × ULN, the AUC of PIVKA-Ⅱ was significantly higher compared to that in patients with TBIL > 1 × ULN(0.817 vs 0.669, P = 0.015), while the difference between ALP ≤ 1 × ULN and ALP > 1 × ULN was not statistically significant(0.783 vs 0.729, P = 0.398). These trends were then more prominently perceived in subgroups of patients with viral etiology and HBV alone.CONCLUSION Serum PIVKA-Ⅱ has better performance in detecting HCC at an early stage for CLD patients with normal serum TBIL.

Staging of liver fibrosis in chronic hepatitis B patients with a composite predictive model:A comparative study

AIM:To evaluate the efficacy of 6 noninvasive liver fibrosis models and to identify the most valuable model for the prediction of liver fibrosis stage in chronic hepatitis B(CHB) patients.METHODS:Seventy-eight CHB patients were consecutively enrolled in this study.Liver biopsy was performed and blood serum was obtained at admission.Histological diagnosis was made according to the METAVIR system.Significant fibrosis was defined as stage score ≥ 2,severe fibrosis as stage score ≥ 3.The diagnostic accuracy of 6 noninvasive liver fibrosis models,including serum aspartate aminotransferase(AST) to platelet ratio index(APRI),FIB-4,Forn's index,Fibrometer,Hepascore,and Shanghai Liver Fibrosis Group's index(SLFG),was investigated.RESULTS:The APRI,FIB-4 and Forn's index under receiver operating characteristic curve(AUROC) for sig-nificant fibrosis were 0.71,0.75 and 0.79,respectively,with a diagnosis accuracy of 67%,77% and 80%,respectively,and 0.80,0.87 and 0.86,respectively,under the AUROC for severe fibrosis.The Hepascore,SLFG,and Fibrometer were 0.80,0.83 and 0.85,respectively under the AUROC for significant fibrosis(P < 0.01).The diagnosis accuracy of Hepascore and SLFG was 86% and 88%,respectively.The Hepascore,SLFG,and Fibrometer were 0.95,0.93,and 0.94,respectively,under the AUROC for severe fibrosis(P < 0.01).CONCLUSION:The models containing direct serum markers have a better diagnostic value than those not containing direct serum markers.

Is the neutrophil to lymphocyte ratio associated with liver fibrosis in patients with chronic hepatitis B?

AIM: To determine the association between the neutrophil to lymphocyte(N/L) ratio and the degree of liver fibrosis in patients with chronic hepatitis B(CHB) infection. METHODS: Between December 2011 and February 2013, 129 consecutive CHB patients who were admitted to the study hospitals for histological evaluation of chronic hepatitis B-related liver fibrosis were included in this retrospective study. The patients were divided into two groups based on the fibrosis score: individuals with a fibrosis score of F0 or F1 were included in the "no/minimal liver fibrosis" group, whereas patients with a fibrosis score of F2, F3, or F4 were included in the "advanced liver fibrosis" group. The Statistical Package for Social Sciences 18.0 for Windows was used to analyze the data. A P value of < 0.05 was accepted as statistically significant.RESULTS: Three experienced and blinded pathologists evaluated the fibrotic status and inflammatory activity of 129 liver biopsy samples from the CHB patients. Following histopathological examination, the "no/minimal fibrosis" group included 79 individuals, while the "advanced fibrosis" group included 50 individuals. Mean(N/L) ratio levels were notably lower in patients with advanced fibrosis when compared with patients with no/minimal fibrosis. The mean value of the aspartate aminotransferase-platelet ratio index was markedly higher in cases with advanced fibrosis compared to those with no/minimal fibrosis.CONCLUSION: Reduced levels of the peripheral blood N/L ratio were found to give high sensitivity, specificity and predictive values in CHB patients with significant fibrosis. The prominent finding of our research suggests that the N/L ratio can be used as a novel noninvasive marker of fibrosis in patients with CHB.

Noninvasive Measurement of Liver Fibrosis by Transient Elastography and Influencing Factors in Patients with Chronic Hepatitis B―A Single Center Retrospective Study of 466 Patients

The noninvasive measurement of liver stiffness (LS) was evaluated by transient elastogra-phy (FibroScan) and the possible influencing factors from the patients’ clinical situations including age,gender,liver inflammation represented by alanine transaminase (ALT) and total billirubin (TBIL) level,HBV replication (HBV DNA loads),portal vein pressure (portal vessel diameter,PVD),splenic thick-ness (SPT) and body mass index (BMI) were analyzed in patients with chronic hepatitis B (CHB).A to-tal of 466 patients including 31 patients with acute-on-chronic liver failure (ACLF),and 435 patients with chronic hepatitis B (CHB) among which 82 patients were diagnosed with liver cirrhosis (LC) by clinical manifestations and liver B-type ultrasonic inspection were enrolled at Tongji Hospital from April to December 2009.LS was measured by a FibroScan device (EchoSens,France).Simultaneously,ALT and TBIL levels,HBV DNA loads,PVD,SPT and BMI in all patients were also tested.Forty-one healthy volunteers served as controls.The values of LS were correlated positively with ages of CHB patients and significantly higher in males than in females.In patients with BMI>28 kg/m2 (obesity) and abnormal levels of ALT and TBIL,LS values were significantly increased as compared with those hav-ing normal levels of ALT and TBIL.The patients with ACLF had the highest LS value.Furthermore,LS values in the patients with LC were significantly higher than those in patients without LC.It is concluded that noninvasive measurement of liver fibrosis by FibroScan provides an alternative method to evaluate liver fibrosis of patients with CHB.In order to properly illustrate the stiffness value taken by transient elastography,patients’ gender should be taken into consideration and it is also suggested to avoid possible influencing factors including liver inflammation (high levels of ALT and TBIL) and obesity (high BMI).

Serum N-glycan markers for diagnosing liver fibrosis induced by hepatitis B virus

BACKGROUND Hepatitis B virus (HBV) infection is the primary cause of hepatitis with chronic HBV infection,which may develop into liver fibrosis,cirrhosis and hepatocellular carcinoma.Detection of early-stage fibrosis related to HBV infection is of great clinical significance to block the progression of liver lesion.Direct liver biopsy is regarded as the gold standard to detect and assess fibrosis;however,this method is invasive and prone to clinical sampling error.In order to address these issues,we attempted to find more convenient and effective serum markers for detecting HBV-induced early-stage liver fibrosis.AIM To investigate serum N-glycan profiling related to HBV-induced liver fibrosis and verify multiparameter diagnostic models related to serum N-glycan changes.METHODS N-glycan profiles from the sera of 432 HBV-infected patients with liver fibrosis were analyzed.Significant changed N-glycan levels (peaks)(P <0.05) in differentfibrosis stages were selected in the modeling group,and multiparameter diagnostic models were established based on changed N-glycan levels by logistic regression analysis.The receiver operating characteristic (ROC) curve analysis was performed to evaluate diagnostic efficacy of N-glycans models.These models were then compared with the aspartate aminotransferase to platelet ratio index (APRI),fibrosis index based on the four factors (FIB-4),glutamyltranspeptidase platelet albumin index (S index),GlycoCirrho-test,and GlycoFibro-test.Furthermore,we combined multiparameter diagnostic models with alanine aminotransferase (ALT) and platelet (PLT) tests and compared their diagnostic power.In addition,the diagnostic accuracy of N-glycan models was also verified in the validation group of patients.RESULTS Multiparameter diagnostic models constructed based on N-glycan peak 1,3,4and 8 could distinguish between different stages of liver fibrosis.The area under ROC curves (AUROCs) of Model A and Model B were 0.890 and 0.752,respectively differentiating fibrosis F0-F1 from F2-F4,and F0-F2 from F3-F4,and surpassing other serum panels.However,AUROC (0.747) in Model C used for the diagnosis of F4 from F0-F3 was lower than AUROC (0.795) in FIB-4.In combination with ALT and PLT,the multiparameter models showed better diagnostic power (AUROC=0.912,0.829,0.885,respectively) when compared with other models.In the validation group,the AUROCs of the three combined models (0.929,0.858,and 0.867,respectively) were still satisfactory.We also applied the combined models to distinguish adjacent fibrosis stages of 432patients (F0-F1/F2/F3/F4),and the AUROCs were 0.917,0.720 and 0.785.CONCLUSION Multiparameter models based on serum N-glycans are effective supplementary markers to distinguish between adjacent fibrosis stages of patients caused by HBV,especially in combination with ALT and PLT.

Noninvasive assessment of liver fibrosis with combined serum aminotransferase/platelet ratio index and hyaluronic acid in patients with chronic hepatitis B

AIM： To construct a noninvasive assessment model consisting of routine laboratory data to predict significant fibrosis and cirrhosis in patients with chronic hepatitis B （CHB）. 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.

Novel index for the prediction of significant liver fibrosis and cirrhosis in chronic hepatitis B patients in China

BACKGROUND Noninvasive,practical,and convenient means of detection for the prediction of liver fibrosis and cirrhosis in China are greatly needed.AIM To develop a precise noninvasive test to stage liver fibrosis and cirrhosis.METHODS With liver biopsy as the gold standard,we established a new index,[alkaline phosphatase(U/L)+gamma-glutamyl transpeptidase(U/L)/platelet(109/L)(AGPR)],to predict liver fibrosis and cirrhosis.In addition,we compared the area under the receiver operating characteristic curve(AUROC)of AGPR,gammaglutamyl transpeptidase to platelet ratio,aspartate transaminase to platelet ratio index,and FIB-4 and evaluated the accuracy of these routine laboratory indices in predicting liver fibrosis and cirrhosis.RESULTS Correlation analysis revealed a significant positive correlation between AGPR and liver fibrosis stage(P<0.001).In the training cohort,the AUROC of AGPR was 0.83(95%CI:0.78-0.87)for predicting fibrosis(≥F2),0.84(95%CI:0.79-0.88)for predicting extensive fibrosis(≥F3),and 0.87(95%CI:0.83-0.91)for predicting cirrhosis(F4).In the validation cohort,the AUROCs of AGPR to predict≥F2,≥F3 and F4 were 0.83(95%CI:0.77-0.88),0.83(95%CI:0.77-0.89),and 0.84(95%CI:0.78-0.89),respectively.CONCLUSION The AGPR index should become a new,simple,accurate,and noninvasive marker to predict liver fibrosis and cirrhosis in chronic hepatitis B patients.

Ultrastructure of oval cells in children with chronic hepatitis B,with special emphasis on the stage of liver fibrosis:The first pediatric study

AIM:To investigate the ultrastructure of oval cells in children with chronic hepatitis B,with special emphasis on their location in areas of collagen fibroplasia. METHODS:Morphological investigations were conducted on biopsy material obtained from 40 children,aged 3-16 years with chronic hepatitis B. The stage of fibrosis was assessed histologically using the arbitrary semiquantitative numerical scoring system proposed by Ishak et al. The material for ultrastructural investigation was fixed in glutaraldehyde and paraformaldehyde and processed for transmission-electron microscopic analysis. RESULTS:Ultrastructural examination of biopsy specimens obtained from children with chronic hepatitis B showed the presence of two types of oval cells,the hepatic progenitor cells and intermediate hepatic-like cells. These cells were present in the parenchyma and were seen most commonly in areas of intense periportal fibrosis (at least stage 2 according to Ishak et al) and in the vicinity of the limiting plate of the lobule. The activated nonparenchymal hepatic cells,i.e. transformed hepatic stellate cells and Kupffer cells were seen in close proximity to the intermediate hepatic-like cells. CONCLUSION:We found a distinct relationship between the prevalence of oval cells (hepatic progenitor cells and intermediate hepatocyte-like cells) and fibrosis stage in pediatric patients with chronic hepatitis B.

目的探讨入院时血清转化生长因子-β1(TGF-β1)、Smad同源蛋白2(Smad2)、Smad同源蛋白3(Smad3)及透明质酸(HA)、Ⅲ型前胶原(PCⅢ)、层黏连蛋白(LN)、Ⅳ型胶原(CⅣ)水平与慢性乙型肝炎(CHB)肝纤维化严重程度的相关性及联合检测对疾病预后的预测价值。方法选取河南省中医院2021年3月至2022年3月收治的78例CHB肝纤维化患者作为研究组,选择同期78名健康体检者作为对照组。比较研究组和对照组及不同肝纤维化分期、不同炎症活动分级CHB肝纤维化患者入院时血清TGF-β1、Smad2、Smad3、HA、PCⅢ、LN、CⅣ水平;分析入院时血清TGF-β1、Smad2、Smad3、HA、PCⅢ、LN、CⅣ水平与肝纤维化分期、炎症活动分级的相关性。CHB肝纤维化患者治疗3个月后,根据患者预后分为预后良好和预后不良亚组,比较预后良好和预后不良患者入院时血清TGF-β1、Smad2、Smad3、HA、PCⅢ、LN、CⅣ水平;分析入院时血清TGF-β1、Smad2、Smad3、HA、PCⅢ、LN、CⅣ水平联合检测对CHB肝纤维化患者预后不良的预测价值。结果研究组入院时血清TGF-β1、Smad2、Smad3、HA、LN、PCⅢ、CⅣ高于对照组(P<0.05);不同肝纤维化分期、炎症活动分级CHB肝纤维化患者入院时血清TGF-β1、Smad2、Smad3、HA、LN、PCⅢ、CⅣ比较:S1<S2<S3<S4、G1<G2<G3<G4,差异有统计学意义(P<0.05);入院时血清TGF-β1、Smad2、Smad3、HA、LN、PCⅢ、CⅣ水平与肝纤维化分期、炎症活动分级均呈正相关(P<0.05)。预后良好患者入院时血清TGF-β1、Smad2、Smad3、HA、LN、PCⅢ、CⅣ水平均低于预后不良患者(P<0.05);入院时血清TGF-β1、Smad2、Smad3、HA、LN、PCⅢ、CⅣ水平联合预测肝纤维化患者预后不良的曲线下面积(AUC)优于各指标单一检测(P<0.05)。结论CHB肝纤维化患者入院时血清TGF-β1、Smad2、Smad3、HA、PCⅢ、LN、CⅣ水平均呈现高表达,且与肝纤维化分期、炎症活动分级密切相关,其联合检测对CHB肝纤维化患者预后有较高的预测价值,可用于评估CHB肝纤维化患者病情严重程度和预后,为制定针对性治疗措施提供参考。

慢性HBV感染者外周血可诱导共刺激分子在CD8+ T淋巴细胞的表达及其临床意义

目的 探讨慢性乙型肝炎病毒(HBV)感染者外周血可诱导共刺激分子(ICOS)在CD8+T淋巴细胞的表达特点及临床意义。方法 选取2017年5月—2018年10月就诊的慢性乙型肝炎(CHB)100例、HBV-肝硬化(LC)25例和HBV-慢加急(或亚急)性肝衰竭(ACLF)26例分别纳入CHB组、HBV-LC组和HBV-ACLF组,健康对照(NC)组35例来自同期门诊体检健康者。采用流式细胞仪检测各组ICOS在CD8+T淋巴细胞的表达情况;分析CD8+T淋巴细胞ICOS表达水平与慢性HBV感染者疾病严重程度、HBV-ACLF预后及并发症的相关性;动态观察HBV-ACLF患者治疗过程中CD8+T淋巴细胞ICOS表达变化。结果 HBV-ACLF组外周血CD8+T淋巴细胞ICOS表达比率及平均荧光强度(MFI)均高于CHB组、HBV-LC组和NC组(P<0.05)。慢性HBV感染者ICOS的MFI与白蛋白、胆碱酯酶、总胆固醇、血红蛋白呈负相关(r=-0.263、-0.269、-0.273、-0.302,P=0.003、0.003、0.011、0.004);与直接胆红素、天冬氨酸转氨酶、凝血酶原时间、国际标准化比值呈正相关(r=0.248、0.208、0.331、0.315,P=0.005、0.020、0.003、0.009);与HBV-DNA、腹水及感染无明显相关性(P>0.05)。治疗过程中,HBV-ACLF患者ICOS的MFI无明显改变。但生存组ICOS的MFI在治疗第1周时较治疗前上升(P<0.05)。结论 HBV-ACLF患者外周血CD8+T淋巴细胞ICOS的表达水平明显升高,并与肝脏合成功能、炎症程度及预后相关,治疗早期ICOS水平变化有助于预测慢性HBV感染者的预后。

Liver stiffness measurements in patients with HBV vs HCV chronic hepatitis:A comparative study

AIM:To assess the values of liver stiffness (LS) in pa-tients with hepatitis B virus (HBV) chronic hepatitis and to compare them with those in patients with hepatitis C virus (HCV) chronic hepatitis. METHODS: The study included 140 patients with HBV chronic hepatitis, and 317 patients with HCV chronic hepatitis, in which LS was measured (FibroScan-Echo-sens) and liver biopsy was performed in the same session (assessed according to the Metavir score). RESULTS:According to the Metavir score of the 140 HBV patients: one had F0,32 had F1, 67 had F2,33 had F3 and 7 had F4. Of the 317 HCV patients:5 had F0, 34 had F1, 146 had F2, 93 had F3 and 39 had F4. For the same severity of fibrosis, the mean values of LS in HBV patients were similar to those in HCV patients:F1,6.5±1.9 kPa vs 5.8±2.1 kPa (P=0.0889); F2,7.1±2 kPa vs 6.9±2.5 kPa (P = 0.3369); F3,9.1±3.6 kPa vs 9.9±5 kPa (P=0.7038); F4,19.8± 8.6 kPa vs 17.3±6.1 kPa (P=0.6574). A signif icant direct correlation between LS measurements and fibrosis was found in HCV patients (Spearman’s r=0.578, P<0.0001), as well as in HBV patients (r=0.408, P<0.0001). The correlation was more signif icant in HCV than in HBV patients (Fisher’s Z-test,Z= 2.210,P=0.0271). CONCLUSION:In our group, the mean values of LS in patients with chronic B hepatitis were similar to those in patients with chronic HCV hepatitis, for the same stage of f ibrosis. Also, LS was correlated with the severity of fibrosis both in HBV and HCV chronic hepatitis patients.
