Factors Associated with Hepatic Steatosis in Black African Subjects with Chronic Viral Hepatitis B in Côte d’Ivoire

Context/Objectives: With the progression of the global epidemic of obesity and metabolic syndrome, the coexistence of hepatic steatosis in patients with chronic viral hepatitis B (VHB) is becoming significant. The aim of this work was to determine the factors associated with hepatic steatosis assessed by a Fibroscan with Controlled Attenuation Parameter (CAP) in patients with chronic viral hepatitis B in Côte d’Ivoire. Methods: This was a cross-sectional and analytical study. Data was collected from February 15 to July 31, 2020 in a private hospital structure in the city of Abidjan in Côte d’Ivoire. We included 83 patients with chronic viral hepatitis B. These were black patients, having performed a Fibroscan/CAP during the recruitment period and consenting to participate in the study. Patients with significant alcohol consumption, a secondary cause of hepatic steatosis, or other liver disease regardless of the etiology associated with hepatitis B were not included. Results: The frequency of hepatic steatosis in chronic VHB carriers assessed by the CAP in our study population was 48.19% including 24.10% severe steatosis. Obesity and high LDL cholesterol were statistically correlated with the presence of steatosis in our patients. Patients who had steatosis on ultrasound were 5 times more likely to have steatosis on CAP. Significant fibrosis was not significantly associated with steatosis. Conclusion: Obesity and LDL hypercholesterolemia are the main factors associated with hepatic steatosis detected by Fibroscan/CAP in patients with chronic viral hepatitis B.

Predictive Value of Serum pgRNA on HBeAg Clearance in Patients with Chronic Hepatitis B with Low HBeAg Levels Treated with Pegylated Interferon

Objective:To study the predictive value of serum pregenomic RNA(pgRNA)on HBeAg clearance in patients with chronic hepatitis B with low HBeAg levels during pegylated interferon therapy.Methods:Twenty chronic hepatitis B patients with HBeAg positive and quantitative<50S/CO were selected for this study.The subjects underwent pegylated interferon therapy for 48-96 weeks and were followed up in the outpatient clinic after treatment.The patients were then divided into groups based on whether their HbeAg turned negative.The predictive ability of each indicator for HBeAg negative conversion was evaluated in the HBeAg negative group and the HBeAg positive group.Results:The results of logistic regression analysis suggested that pgRNA and HBcrAg were better indicators for predicting the clearance of HBeAg after treatment.Conclusion:For patients with chronic hepatitis B with low HBeAg levels,pgRNA is a good indicator in predicting HBeAg clearance during pegylated interferon therapy.

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).

Transient elastography in chronic hepatitis B: An Asian perspective

Transient elastography (TE) is a new non-invasive tool for assessing liver stiffness, which is correlated with the histologic stage of liver fibrosis. Many studies have reported a good accuracy of TE in predicting signif icant fibrosis and an optimal accuracy in predicting cirrhosis. Furthermore, the potential role of TE in screening the general population has also been proven. TE thus helps physicians to decide treatment strategies, predict prog-nosis, and monitor disease progression in patients with chronic liver disease and to screen the general popula-tion to identify high risk patients with potential liver disease. However, most data on the clinical roles of TE have been gathered in European patients with chronic hepatitis C (CHC), because TE was first developed in France. Accordingly, much data on the usefulness of TE in patients with CHC has accumulated. Recently, however, vigorous efforts have been made to apply TEto patients with chronic hepatitis B (CHB), and TE has also proved to have acceptable accuracy in diagnosing liver fibrosis and cirrhosis in these patients. Thus, we focused on TE in the Asian population with CHB in comparison with the European population with CHC and found that the diagnostic performance and cutoff values were different between the 2 populations possibly as a result of several different confounders between Asian and European populations (the etiology of chronic liver disease, histologic features, major fluctuation in alanine aminotransferase levels, and the prevalence of high body mass index and metabolic syndrome). Therefore, further studies tailored to the Asian population with CHB should be performed before the widespread application of TE in Asian populations with CHB.

目的探讨FibroScan肝脏硬度值(LSM)测定对乙型肝炎病毒相关慢加急性肝衰竭(HBV-ACLF)患者短期预后的预测价值。方法收集2019年10月至2021年12月在麻城市人民医院感染科住院的80例HBV-ACLF患者作为研究对象,根据出院随访12周的预后情况将其分为预后良好组(38例)及预后不良组(42例)。检测两组的各项指标,计算终末期肝病模型(MELD)评分。分析影响HBV-ACLF患者短期预后的因素、LSM与MELD评分的相关性及LSM、MELD评分、LSM联合MELD评分对HBV-ACLF短期不良预后的预测价值。结果两组患者的性别、年龄、血小板计数(PLT)、丙氨酸氨基转移酶(ALT)、天门冬氨酸氨基转移酶(AST)、Na+、甲胎蛋白(AFP)比较,差异无统计学意义(P>0.05);两组的白细胞计数(WBC)、总胆红素(TBIL)、直接胆红素(DBIL)、血清肌酐(Scr)、凝血酶原时间(PT)、国际标准化比值(INR)、LSM、MELD评分比较,差异具有统计学意义(P<0.05)。LSM、MELD评分是HBV-ACLF短期预后的影响因素(P<0.05)。LSM与MELD评分呈正相关(r=0.564,P<0.05)。LSM联合MELD评分的预测效能优于LSM及MELD评分,差异具有统计学意义(P<0.05)。结论LSM与HBV-ACLF患者的短期预后具有相关性,LSM联合MELD评分可用于该患者短期不良预后的评估,有较高的灵敏度及特异度,具有一定的应用价值。

Prognostic value of M30/M65 for outcome of hepatitis B virus-related acute-on-chronic liver failure

AIM:To determine the prognostic value of circulating indicators of cell death in acute-on-chronic liver failure(ACLF)patients with chronic hepatitis B virus(HBV)infection as the single etiology.METHODS:Full length and caspase cleaved cytokeratin 18(detected as M65 and M30 antigens)represent circulating indicators of necrosis and apoptosis.M65and M30 were identified by enzyme-linked immunosorbent assay in 169 subjects including healthy controls(n=33),patients with chronic hepatitis B(CHB,n=55)and patients with ACLF(n=81).According to the 3-mo survival period,ACLF patients were defined as having spontaneous recovery(n=33)and non-spontaneous recovery which included deceased patients and those who required liver transplantation(n=48).RESULTS:Both biomarker levels significantly increased gradually as liver disease progressed(for M65:P<0.001 for all;for M30:control vs CHB,P=0.072;others:P<0.001 for all).In contrast,the M30/M65 ratio was significantly higher in controls compared with CHB patients(P=0.010)or ACLF patients(P<0.001).In addition,the area under receiver operating characteristic curve(AUC)analysis demonstrated that both biomarkers had diagnostic value(AUC≥0.80)in identifying ACLF from CHB patients.Interestingly,it is worth noting that the M30/M65 ratio was significantly different between spontaneous and non-spontaneous recovery in ACLF patients(P=0.032).The prognostic value of the M30/M65 ratio was compared with the Model for End-Stage Liver Disease(MELD)and Child-Pugh scores at the 3-mo survival period,the AUC of the M30/M65ratio was 0.66 with a sensitivity of 52.9%and the highest specificity of 92.6%(MELD:AUC=0.71;sensitivity,79.4%;specificity,63.0%;Child-Pugh:AUC=0.77;sensitivity,61.8%;specificity,88.9%).CONCLUSION:M65 and M30 are strongly associated with liver disease severity.The M30/M65 ratio may be a potential prognostic marker for spontaneous recovery in patients with HBV-related ACLF.

TT virus and hepatitis G virus infections in Korean blood donors and patients with chronic liver disease

AIM: To determine the prevalences of TTV and HGV infections among blood donors and patients with chronic liver disease in Korea, to investigate the association of TTV and HGV infections with blood transfusion, and to assess the correlation between TTV and HGV viremia and hepatic damage.METHODS: A total of 391 serum samples were examined in this study. Samples were obtained from healthy blood donors (n= 110), hepatitis B surface antigen (HBsAg)-positive donors (n=112), anti-hepatitis C virus (anti-HCV)-positive donors (n=69), patients with type B chronic liver disease (n=81), and patients with type C chronic liver disease (n= 19).TTV DNA was detected using the hemi-nested PCR. HGV RNA was tested using RT-PCR. A history of blood transfusion and serum levels of alanine aminotransferase (ALT) and aspartate aminotransferase (AST) were also determined.RESULTS: TTV DNA was detected in 8.2 % of healthy blood donors, 16.1% of HBsAg-positive donors, 20.3 % of antiHCV-positive donors, 21.0 % of patients with type B chronic liver disease, and 21.1% of patients with type C chronic liver disease. HGV RNA was detected in 1.8 % of healthy blood donors, 1.8 % of HBsAg-positive donors, 17.4 % of anti-HCV-positive donors, 13.6% of patients with type B chronic liver disease, and 10.5% of patients with type C chronic liver disease. The prevalence of TTV and HGV infections in HBV- or HCV-positive donors and patients was significantly higher than in healthy blood donors (P＜0.05),except for the detection rate of HGV in HBsAg-positive donors which was the same as for healthy donors. There was a history of transfusion in 66.7% of TTV DNA-positive patients and 76.9% of HGV RNA-positive patients (P＜0.05). No significant increase in serum ALT and AST was detected in the TTV- or HGV-positive donors and patients.CONCLUSION: TTV and HGV infections are more frequently found in donors and patients infected with HBV or HCV than in healthy blood donors. However, there is no significant association between TTV or HGV infections and liver injury.

目的探讨肝脏瞬时弹性超声成像(Fibroscan,FS)在评估慢性乙型肝炎肝纤维化中的作用及影响因素。方法选择上海瑞金医院感染科2009年1月至2011年12月慢性乙型肝炎(CHB)患者410例,运用FS检测肝脏硬度值(Stiffness值)。所有患者同期行经皮肝穿刺活组织检查,同时检测肝功能、血小板、凝血等指标。以肝活检结果为标准绘制FS工作特征曲线,计算受试者工作特征曲线下面积(AUROC),Stiffness值与Ishak评分比对,运用统计学方法进行分析。结果无肝纤维化(S0期)、轻度肝纤维化(S1～S2期)、中度肝纤维化(S3～S4期)和重度肝纤维化及肝硬化(S5期～S6期)患者Stiffness值(kPa)分别为5.45±1.44、7.01±2.42、9.23±3.00、16.87±6.77,对Stiffness值进行组间比较,差异有统计学意义(P<0.01)。Stiffness值与肝纤维化分期呈显著正相关(r=0.67812,P<0.01)。Fibroscan检测显著肝纤维化和肝硬化的AUROC分别为0.840和0.938,其中以Stiffness值8.050kPa作为显著肝纤维化的诊断界值,敏感度为60.3%,特异度为93.7%,阳性预测值为94.71%,阴性预测值为55.83%;以12.150kPa作为重度肝纤维化和肝硬化的诊断界值点,敏感度和特异度分别为75.9%和92.0%,阳性预测值和阴性预测值分别为61.11%和95.86%。逐步回归统计分析,Alb、PLT、AST、年龄、体质量对Stiffness值有影响。结论 Fibroscan评估CHB患者肝纤维化程度尤其是显著肝纤维化和肝硬化准确性高,在诊断与疗效评估中具有较好的应用价值。

FibroScan联合GGT/PLT比值预测慢性乙型肝炎患者肝纤维化的初步探讨

目的初步探讨FibroScan联合GGT/PLT比值(GPR)预测慢性乙型肝炎(CHB)患者肝纤维化分期的诊断价值。方法选取广州市第八人民医院2012年1月-2016年12月肝活组织检查诊断为CHB患者278例,分析GPR、FibroScan以及二者联合诊断预测纤维化分期(F0～F4)的价值。非正态分布的计量资料多组间比较采用Kruskal-Wallis H检验,进一步两两比较采用MannWhitney U检验。相关性分析采用Spearman相关系数。受试者工作特征曲线下面积(AUC)评估肝纤维化分期。结果以肝活组织检查作为金标准,F1～F4期患者分别有50、104、92和32例。随着肝纤维化分期加重,FibroScan检测肝硬度值(LSM)逐渐升高(P值均<0. 05); GPR在肝纤维化F1、F2、F3期逐渐升高(P值均<0. 05)。GPR、FibroScan均与肝纤维化呈正相关(r值分别为0. 419、0. 481,P值均<0. 001); GPR与FibroScan呈正相关(r=0. 436,P <0. 001)。FibroScan与GPR联合预测进展期肝纤维化(≥F3)的诊断效能优于单一FibroScan(AUC:0. 793 vs 0. 739,Z=3. 044,P=0. 002)或GPR(AUC:0. 793 vs 0. 740,Z=2. 389,P=0. 037);二者联合预测明显肝纤维化(≥F2)的诊断效能优于单一GPR(AUC:0. 782 vs 0. 714,Z=2. 130,P=0. 033)。结论 FibroScan与GPR联合诊断对于预测CHB进展期肝纤维化(≥F3)具有优势,初步认为可提高诊断效能。
