This study was designed to explore the effect of IL-18 on peripheral blood mononuclear cells ( PBMCs) derived from chronic hepatitis B (CHB) and on hepatitis B virus (HBV) DNA released by HepG2.2.15 cell lines, which were transfected with hepatitis B virus gene in vitro. METHODS: PBMCs isolated from 25 healthy people and 25 patients with CHB were stimulated with HBcAg and IL-18 of various concentrations for 72 hours. The levels of IFN-γ in the supernatants of cultured PBMCs were determined by ELISA. After the stimulation of IL-18 of various concentra- tions, PBMCs derived from one patient were co-cultured for 96 hours with HepG2. 2. 15 cells which had been cul- tured for 24 hours, and then the supernatants were collected by centrifugation and used for HBV DNA quantitative as- say. RESULTS: When PBMCs were stimulated by HBcAg and IL-18 at various concentrations, the levels of IFN-γ in the supernatants of CHB groups were much higher than those in normal control groups, at 0.2 ng/ml: t =11.70, P< 0.01; at 1.0 ng/ml: t =16.19, P<0.01; and at5.0 ng/ml: t =20.12, P <0.01. In the CHB groups, the levels of IFN-γ in the supernatants of PBMCs stimulated by HBcAg alone were lower than both those stimulated by HBcAg and EL-18 at various concentrations and those stimulated by HBcAg and EL-18 (5.0 ng/ml) together with EL-12 (mild: t = 2.20, P<0.05; moderate; t=2.97, P<0.05; severe; t = 0.66, P >0.05). The content of HBV DNA in the superna- tant of co-cultivation of HepG2. 2. 15 cells and PBMCs without stimulated materials was higher than that stimula-ted by HBcAg and EL-18 at various concentrations of HBc- Ag and IL-18 together with IL-12/IFN-α1lb. CONCLUSION: DL-18 can induce IFN-γ secretion and pro- bably play a key role in the modulation of both innate and adaptive immunity. It has implications in improving im- munoregulatory effect and increasing the ability of immune cells to kill cells infected by virus.展开更多

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). Trv 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 anti- HCV-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

Toll-like receptors (TLRs) have been shown previously to play a pivotal role in the activation of innate immunity. The purpose of this study was.to characterize the TLR4 expression in peripheral blood mononuclear cells (PBMCs) of ACLF pa- tients and its possible role in the disease aggravation. Twelve healthy subjects, 15 chronic HBV-infected (CHB) patients and 15 ACLF patients were enrolled in this study. The TLR4 expression in PBMCs and T cells of all subjects was examined by real-time PCR and flow cytometry. The correlation of TLR4 ex- pression on T cells with the markers of disease aggravation was evaluated in ACLF patients. The ability of TLR4 ligands stimulation to induce inflammatory cytokine production in ACLF patients was ana- lyzed by flow cytometry. The results showed that TLR4 mRNA level was upregulated in PBMCs of ACLF patients compared to that in the healthy subjects and the CHB patients. Specifically, the expres- sion of TLR4 on CD4+ and CD8+ T cells of PBMCs was significantly increased in ACLF patients. The TLR4 levels on CD4+ and CD8+T cells were positively correlated with serum total bilirubin (TBIL), direct bilirubin (DBIL), international normalized ratio (INR) levels and white blood cells (WBCs), and negatively correlated with serum albumin (ALB) levels in the HBV-infected patients, indicating TLR4 pathway may play a role in the disease aggravation of ACLF. In vitro TLR4 ligand stimulation on PBMCs of ACLF patients induced a strong TNF-α production by CD4+ T cells, which was also posi- tively correlated with the serum markers for liver injury severity. It was concluded that TLR4 expression is upregulated on T cells in PBMCs, which is associated with the aggravation of ACLF.展开更多

文摘Summary: Immune-mediated inflammatory injury is an important feature of the disease aggravation of hepatitis B virus-related acute-on-chronic liver failure (ACLF). Toll-like receptors (TLRs) have been shown previously to play a pivotal role in the activation of innate immunity. The purpose of this study was.to characterize the TLR4 expression in peripheral blood mononuclear cells (PBMCs) of ACLF pa- tients and its possible role in the disease aggravation. Twelve healthy subjects, 15 chronic HBV-infected (CHB) patients and 15 ACLF patients were enrolled in this study. The TLR4 expression in PBMCs and T cells of all subjects was examined by real-time PCR and flow cytometry. The correlation of TLR4 ex- pression on T cells with the markers of disease aggravation was evaluated in ACLF patients. The ability of TLR4 ligands stimulation to induce inflammatory cytokine production in ACLF patients was ana- lyzed by flow cytometry. The results showed that TLR4 mRNA level was upregulated in PBMCs of ACLF patients compared to that in the healthy subjects and the CHB patients.

In vitro TLR4 ligand stimulation on PBMCs of ACLF patients induced a strong TNF-α production by CD4+ T cells, which was also posi- tively correlated with the serum markers for liver injury severity. It was concluded that TLR4 expression is upregulated on T cells in PBMCs, which is associated with the aggravation of ACLF.
文摘Occult hepatitis B virus(HBV) infection(OBI) is defined by the presence of HBV DNA in the liver tissue of individuals who test negative for hepatitis B surface antigen(HBsAg).Patients who have recovered from acute hepatitis B can carry HBV genomes for a long time and show histological patterns of mild necro-inflammation,even fibrosis,years after the resolution of acute hepatitis,without showing any clinical or biochemical evidence of liver disease.At least in conditions of immunocompetence,OBI is inoffensive itself,but when other relevant causes of liver damage are present it might make the course of the liver disease worse.The risk of HBV transmission through transfusion is related to blood donations negative for HBsAg that have been collected during the pre-seroconversion period or during chronic OBI.Use of HBV nucleic acid amplification testing and multivalent anti-HBs antibodies in the HBsAg assays is recommended for detection of true and false OBI,respectively.It is not known if prior hepatitis B immunization with an optimal anti-HBs response in cases of HBV transmission through organ transplantation can effectively modulate or abort the infection.Use of anti-viral agents as prophylaxis in patients with serological evidence of past HBV infection prevents reactivation of OBI after transplantation in most cases.Reactivation of OBI has been observed in other conditions that cause immunosuppression,in which antiviral therapy could be delayed until the HBV DNA or HBsAg becomes detectable.OBI might contribute to the progression of liver fibrosis and hepatocellular carcinoma development in patients with chronic liver disease.
文摘目的 探究血小板(PLT)计数与HBV相关慢加急性肝衰竭(HBV-ACLF)预后的相关性,建立新的PLT相关评分模型并评估其在HBV-ACLF短期预后中的预测价值。方法 选取2018年1月—2022年1月于西部战区总医院消化内科住院治疗的HBV-ACLF患者作为回顾性研究队列。收集所有患者入院24 h内的临床资料,根据随访180天后的生存情况将患者分为生存组和死亡组。符合正态分布的计量资料组间比较采用成组t检验;不符合正态分布的计量资料组间比较采用Mann-Whitney U检验;计数资料组间比较采用χ^(2)检验。采用Pearson相关系数分析各指标之间相关性。采用Logistic回归模型进行预后影响因素分析。采用受试者工作曲线评估预后模型预测价值。通过Kaplan-Meier曲线分析患者生存情况。结果 共纳入236例患者,180天生存率为75.85%(179/236)。死亡组年龄[(53.98±10.45)岁vs (47.44±12.46)岁,P=0.001]、INR[1.78(1.46~2.04) vs 1.47(1.23~1.68),P<0.001]、TBil[275.60(165.00~451.45)μmol/L vs 230.60(154.90~323.70)μmol/L,P=0.035]、MELD评分[21.47(18.14~24.76)分vs 18.67(15.70~21.62)分,P<0.001]、ALBI评分[-1.06(-1.64~-0.86)分vs-1.32(-1.73~-1.01)分,P=0.034]高于生存组,PLT水平[80.00(50.00~124.50)×109/L vs 115.00(82.00~143.00)×109/L,P=0.001]、PWR[13.40(9.54~20.70) vs 18.49(13.95~24.74),P=0.001]低于生存组,差异均有统计学意义。Pearson相关性分析显示,PLT与肝硬化的发生及INR呈负相关(r值分别为-0.332、-0.194,P值分别为<0.001、0.003)。多因素Logistic回归分析显示,年龄、PLT、INR为HBV-ACLF患者180天预后的独立影响因素(OR值分别为1.045、0.990、2.591,95%CI分别为1.015~1.076、0.983~0.998、1.363~4.925)。获得新的预测模型:AIP=0.006×年龄+0.187×INR-0.001×PLT。AIP评分模型对预测HBV-ACLF患者180天生存率曲线下面积(AUC)为0.718 (敏感度为81.1%,特异度为54.1%),而PLT、PWR、LPACLF评分、MELD评分、ALBI评分的AUC分别为0.673、0.659、0.588、0.647、0.578。AIP评分模型的cut-off值为0.48。Kaplan-Meier生存分析发现,高AIP评分组的生存率明显低于低AIP评分组(P<0.001)。结论 PLT相关评分模型对HBV-ACLF预后的预测价值优于其他模型,高PLT水平HBV-ACLF患者的整体生存率更高。

文摘Objective:To investigate the correlation between T lymphocytes and biochemical indices in patients with Primary liver cancer(PLC)associated with hepatitis B virus(HBV)and TCM syndrome differentiation.Methods:263 HBV-related PLC patients who were admitted to the First Affiliated Hospital of Henan University of Traditional Chinese Medicine from January 2018 to December 2019 were retrospectively collected.There were 127 cases of liver depression and spleen deficiency syndrome(48.3%),48 cases of spleen deficiency and dampness syndrome(18.3%),31 cases of liver and gallbladder dampness and heat syndrome(11.8%),35 cases of liver and blood stasis syndrome(13.3%),and 22 cases of liver and kidney Yin deficiency syndrome(8.4%).The general data,T cell subsets,oncology and virology indicators,oncology characteristics,biochemical indicators and other data were counted.Epidata and Excel were used to collect and summarize the data,and SPSS26.0 software was used for statistical analysis.Results:There was no significant difference in gender and age distribution among the five syndrome types(χ^(2)=5.462,F=1.979,ALL P>0.05).The differences among T lymphocyte count(χ^(2)=57.785,P<0.001),CD4(+)T cell count(χ^(2)=47.103,P<0.001)and CD8(+)T lymphocyte count(F=12.760,P<0.001)were statistically significant.The T lymphocyte count,CD4(+)T lymphocyte count and CD8(+)T lymphocyte explicit count in patients with liver and kidney Yin deficiency syndrome were significantly lower than those in the other four syndrome types.AFP(χ^(2)=89.986,P<0.001),CEA(χ^(2)=95.501,P<0.001),CA199(χ^(2)=30.044,P<0.001)of the five syndrome types increased successively from the syndrome of liver depression and spleen deficiency to the syndrome of liver and kidney Yin deficiency,and the difference was statistically significant.There were statistically significant differences in the inner diameter of main portal vein,portal vein cancer thrombin and extrahepatic metastasis among the five syndrome types(ALL P<0.001).The main symptoms of portal vein cancer thrombin and extrahepatic metastasis were liver-gallbladder dampness-heat syndrome and liver-blood stasis syndrome.The differences among PLT(χ^(2)=39.234,P<0.001),Alb(χ^(2)=75.171,P<0.001),TBil(χ^(2)=51.140,P<0.001),AST(χ^(2)=55.881,P<0.001),PT(χ^(2)=21.515,P<0.001)were statistically significant.PLT and Alb decreased successively from the syndrome of liver depression and spleen deficiency to the syndrome of liver and kidney Yin deficiency.PLT and Alb of the syndrome of liver depression and spleen deficiency were significantly higher than those of the other four groups,and TBil and AST of the syndrome of liver and gallbladder dampness and heat were significantly higher than those of the other four groups.PT of liver and kidney Yin deficiency was significantly higher than that of the other four groups.The lymphocyte count,CD4(+) lymphocyte count and CD8(+) lymphocyte count were negatively correlated with AFP,PT and TBil(ALL P<0.05),and positively correlated with PLT(P<0.05).T lymphocyte count was positively correlated with AIb(P<0.05).Conclusion:This study found that patients with liver depression and spleen deficiency syndrome have better cellular immune function,liver function and prognosis.Patients with liver and kidney Yin deficiency have lower cellular immunity,worse liver function,and worse prognosis.Portal vein carcinoma embolus and extrahepatic metastasis were mainly characterized by dampness and heat of liver and gallbladder and blood stasis of liver.Patients with lower lymphocyte counts have poorer blood clotting,worse the liver reserve,and the higher the risk of further cancer.
文摘慢性乙型肝炎病毒(hepatitis B virus,HBV)感染的防治依然任重而道远.即使我国新版指南扩大了抗病毒治疗适应证,依然有一定比例的HBV感染者不符合抗病毒治疗适应证,称之为不确定期或灰区(grey zone,GZ).但当前关于不确定期或GZ的解读与判断标准较为混乱,两者之间的联系与区别还不甚清晰,不同研究所指向的对象不尽相同.但无论如何认定不确定期或GZ,其目的是为了及时、准确判断慢性HBV感染的疾病进展与是否需要及时治疗.基于GZ对应于“治疗的适应证分类”和不确定期对应于“自然史分期”的理解,本文结合国内外的研究进展阐述对慢性HBV感染不确定期与GZ的再认识.GZ即为不治疗对象(不符合抗病毒治疗适应证),而不确定期仅为难以明确归于自然史分期(不符合自然史分期)的患者,GZ应包括不确定期,而不是等同关系.对应我国新版指南标准,属于GZ的不确定期患者,建议抗病毒治疗;对应欧洲肝病学会2017年指南标准,免疫控制期与属于GZ的不确定期患者,建议抗病毒治疗.
