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.展开更多

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.展开更多

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.展开更多

文摘目的比较Fibro Scan诊断不同类型慢性肝病肝纤维化的异同性。方法收集2012年10月-2015年1月就诊于北京大学第一医院的516例慢性肝病患者的临床资料,按照病因分为慢性乙型肝炎(CHB)组(n=305)、慢性丙型肝炎(CHC)组(n=117)及原发性胆汁性肝硬化(PBC)组(n=94),记录所有患者血常规、肝功能、肝脏弹性(FS)值以及腹部B超检查结果。按照FS值<7.3 k Pa、7.3 k Pa≤FS值<15 k Pa、FS值≥15 k Pa将每组患者分为不同的FS等级。计量资料和计数资料多组间比较采用KruskalWallis H检验,两组间比较采用Mann-Whitney U检验;FS值与年龄、性别、BMI、血常规、肝功能、超声各指标的相关性采用多重线性回归方法进行分析。结果 CHB组患者FS值的独立影响因素为性别、血红蛋白、AST、白蛋白、ALP、TBil、BMI、门静脉内径、腹水(P值均<0.05);CHC组患者FS值的独立影响因素为血小板、ALT、ALP、GGT、总胆汁酸、肝表面光滑度、脾静脉内径、腹水(P值均<0.05);PBC组患者FS值的独立影响因素为TBil、总胆汁酸、腹水(P值均<0.05)。CHB和CHC患者不同FS值等级组间绝大多数检测指标的差异均有统计学意义(P值均<0.05);PBC组中FS值<7.3 k Pa与7.3 k Pa≤FS值<15 k Pa组间仅有ALT(Z=-2.121,P=0.034)、AST(Z=-3.027,P=0.002)、脾长度(Z=-2.496,P=0.013)差异有统计学意义;7.3 k Pa≤FS值<15 k Pa与FS值≥15 k Pa组间血小板(Z=-2.289,P=0.022)、白蛋白(Z=-2.185,P=0.029)、TBil(Z=-2.642,P=0.008)、脾厚度(Z=-3.317,P=0.001)、脾长度(Z=-2.010,P=0.044)、脾静脉内径(Z=-2.296,P=0.022)差异有统计学意义。结论不同病因影响FS值的关键因素有所不同,总胆汁酸、TBil是PBC患者FS值的重要影响因素,而肝功能状态对CHB和CHC患者FS值的影响更为显著,提示Fibro Scan诊断肝纤维化的阈值设定要根据不同病因病种而异。
