肝组织炎症对FibroScan诊断慢性乙型肝炎患者肝纤维化的影响

目的探讨肝组织学炎症对瞬时弹性扫描仪（FS）诊断慢性乙型肝炎患者肝纤维化的影响。方法应用FS对124名慢性乙型肝炎患者进行肝穿刺前肝脏弹性测量值（LSM）的测定,采用肝穿刺活组织病理诊断技术进行肝纤维化分期（S）和炎症分级（G）。对同一肝纤维化分期不同肝组织炎症分级组间LSM进行比较,并对各肝纤维化分期中LSM与肝组织炎症分级进行相关性分析。结果肝组织纤维化逐渐发展伴随肝炎症程度加重,如肝纤维化S1期患者中以G1为主（81.8%）,S2期以G2为主（54.2%）,S3期以G3为主（47.4%）,S4期以G3、G4为主（40%,33.4%）,S1～S4每一纤维化分期水平上,不同炎症分级LSM差异均具有统计学意义（P〈0.05）,且LSM与不同炎症分级之间均呈显著正相关（P〈0.01）。结论肝组织炎症程度是影响FS诊断的一个重要因素,炎症活动程度加重可使LSM增加。     

慢性乙型肝炎患者血清HBeAg、HBV DNA与肝组织炎症关系的探讨

目的探讨慢性乙型肝炎血清HBeAg及HBV DNA水平和肝组织炎症损害的关系.方法采用微粒子免疫捕捉分析法和荧光定量聚合酶链反应分别对74例HBeAg阴性和73例HBeAg阳性慢性乙型肝炎患者进行血清HBeAg、HBV DNA定量检测和肝组织活检病理炎症分级,对比分析结果.结果74例HBeAg阴性慢性乙型肝炎患者中27例（36%）血清HBV DNA＞105拷贝/ml,随着G1～G4肝组织炎症损害级别的增高其所占例数也相应增高,统计学分析HBV DNA水平与肝组织炎症病理分级的相关性有显著意义;血清HBeAg定量0～29 PEIU/ml,随肝组织炎症病理分级上升定量阳性（＞0.28 PEIU/ml）的病例比率增加,经统计学分析两者具有相关性.73例HBeAg阳性慢性乙型肝炎患者中有49例（67%）血清HBV DNA＞105拷贝/ml,血清HBeAg及HBV DNA水平与肝组织炎症分级无相关性.结论血清HBV DNA水平可作为判断HBeAg阴性慢性乙型肝炎患者肝组织炎症损害程度的指标,血清HBV DNA水平愈高肝组织炎症损害往往愈重.36%的HBeAg阴性慢性乙型肝炎患者血清HBeAg水平低下而HBV DNA复制活跃,可能存在HBV的前C区终止突变合并C区突变.血清HBV DNA水平不能反映HBeAg阳性慢性乙型肝炎肝组织炎症损害的程度.

目的探讨慢性乙型肝炎病毒感染者自然病程进展规律及其与感染持续时间、血清HBV DNA载量、HBe Ag状态和脾脏厚度的关系。方法 2007年1月至2010年8月就诊于中国医科大学附属盛京医院感染病科的家族聚集性慢性乙型肝炎病毒感染者132例,常规行肝组织活检病理学检查,采用化学发光法检测血清HBV标记物;采用荧光定量PCR法检测血清HBV DNA;使用西门子S200二维彩超诊断仪测量脾脏厚度。结果在132例慢性乙型肝炎患者中,年龄≥30岁患者肝组织炎症评分≥5分和纤维化评分≥3分发生率分别为33.3%和38.4%,显著高于年龄30岁组(14.9%和14.8%,P0.05);肝功能正常组肝组织炎症评分≤4分和纤维化评分≤2分发生率分别为92.0%和92.0%,肝功能异常组为53.6%和16.74%(P0.05);肝功能反复异常1年的患者肝组织炎症评分≥5分和纤维化评分≥3分发生率分别为42.8%和51.5%,显著高于肝功能异常≤1年组(31.9%和31.9%,P0.05);血清HBV DNA载量为3~5 lg copies/ml组肝组织炎症评分为≤4分和纤维化评分为≤2分发生率分别为50.0%和27.8%,显著高于病毒载量3 lg copies/ml组(P0.05);血清HBe Ag阴性组纤维化评分在3~4分和≥5分发生率分别为23.1%和20.5%,显著高于HBe Ag阳性组的11.8%和9.7%(P0.05);血清HBe Ag阳性与否与肝组织炎症无显著相关性(P0.05);脾脏厚度≥4 cm组肝组织炎症≥5分和纤维化评分≥5分发生率分别为76.9%、7.7%和76.9%,显著高于脾脏厚度4 cm组的16.0%、3.4%和5.9%(P0.05);多因素分析发现脾脏厚度与肝组织炎症(t=2.153)和纤维化程度(t=4.654)呈显著独立正相关(P=0.033);血清HBV DNA载量与肝组织纤维化程度(t=-2.826)也呈独立相关(P=0.005)。结论家族聚集性的慢性乙型肝炎病毒感染者肝组织炎症和纤维化程度与感染持续时间成正相关,年龄大于30岁时更易出现肝脏疾病的进展。肝功能异常时间越长肝脏炎症和纤维化改变越显著。脾脏厚度与肝组织炎症和纤维化程度具有独立正相关。血清HBV DNA载量为1×103~105copies/ml时肝组织炎症和纤维化改变更显著。     

血清胶原酶对判断慢性乙型肝炎肝纤维化及炎症程度的意义

目的观察慢性乙型肝炎患者血清基质金属蛋白酶(MMPs)及金属蛋白酶组织抑制因子(TIMPs)水平与肝纤维化及炎症程度的相关性,寻找新的判定肝纤维化程度的血清学指标.方法慢性乙型肝炎患者88例,间隔半年行两次肝穿刺活检,病理组织进行炎症活动度及纤维化程度半定量计分;检测血清TIMP1、TIMP2、MMP1、MMP2、MMP9、Ⅳ型胶原、层黏连蛋白、Ⅲ型前胶原N端肽、透明质酸水平.结果血清TIMP1(r=0.540,P＜0.001)、MMP2(r=0.314,P=0.003)、TIMP1/MMP1(r=0.269,P＜0.001)与纤维化分级成正相关,MMP1与纤维化分级成负相关(r=-0.49 5,P＜0.001),且与血清Ⅲ型前胶原N端肽、透明质酸相关;根据受试者工作特性曲线(ROC)下面积计算,MMP1以13.96(ng/ml)为临界值,判别S2及S2以上纤维化的敏感性为90.5%,特异性为52.0%;TIMP1以76.84(ng/ml)为临界值,敏感性为91.6%,特异性为64.0%.MMP1以6.86(ng/ml)为临界值,判别肝硬化(S4)期敏感性为70.7%,特异性为80.9%;TIMP1以210.04(ng/ml)为临界值,其敏感性60.5%,特异性92.3%.MMP1、TIMP1与炎症分级及计分均有相关性,而TIMP1与碎屑坏死、桥接坏死相关性最好(r=0.435,P＜0.001),TIMP2与MMP9与炎症没有明显相关性.结论血清TIMP1、MMP1、MMP2水平、TIMP1/MMP1比值可作评估肝纤维化发展或减轻的指标.     

慢性乙型肝炎的病理与临床

目的：提高慢性乙型肝炎临床诊断的正确性。方法：对202例慢性乙型肝炎患者的临床表现，血液生物化学指标[血清总胆红素（TBil)，白蛋白(ALB),凝血酶原活动度（PTA），ALT，白蛋白／球蛋白比值（A／G），r-球蛋白（GGT）]与病理分级分度进行对比分析。结果：临床表现如乏力，纳差，厌油，腹胀，鼻／牙龈出血及肝掌，蜘蛛痣，脾静脉增宽,胆囊炎与肝组织炎症活动密切相关；TBil,ALT,GGT上升及Alb,A/G比值，PTA下降均与肝组织炎症程度加重有关。6项指标中，轻度慢性肝炎临床与病理诊断符合率较高，为63.8%-79.0% ,其次为重度慢性肝炎，为40.0%-62.5%，符合率最低的是中度慢性肝炎，为10.0%-28.2%。结论：临床诊断时要高度重视临床症状，体征的变化，可适当放宽临床分度中有关中度异常值范围。     

HBeAg阳性和阴性的慢性乙型肝炎患者组织病理学及免疫组化学研究

Clinical significance of liver biopsy in chronic hepatitis B patients with persistently normal transaminase

OBJECTIVE: The aim of this study was to study the clinical significance of liver biopsy for individuals who had chronic hepatitis B virus infection and persistently normal serum transaminases for more than 6 months. METHODS: A total of 452 patients with positive hepatitis B surface antigen for over 6 months underwent percutaneous liver biopsy. All liver biopsy specimens were assessed by experienced liver pathologists blinded to the liver biochemistry, and were scored according to the modified criteria of grade and stage of chronic hepatitis. Patients were divided into four groups: group A and group C patients had normal transaminases, and were hepatitis B e antigen (HBeAg) positive and HBeAg negative, respectively; group B and group D patients had elevated transaminases, and were HBeAg positive and HBeAg negative, respectively. RESULTS: All patients had necrosis and inflammation in the liver. Patients with increased serum transaminases had a significantly higher grade (G) of hepatic necrosis and inflammation and more severe (S) fibrosis compared with patients with normal transaminases (P < 0.05). However, in the latter patients, G3 was seen in 10 (5.5%) and 13 cases (9.1%), S3 in seven (3.8%) and 16 cases (11.1%), and S4 in three (1.6%) and seven cases (4.9%) in Group A and Group C, respectively. Moreover, in patients with normal transaminases, the HBeAg‐negative group had more severe fibrosis than the HBeAg‐positive group (P < 0.05). CONCLUSION: Although more severe pathological changes were more frequent in patients with elevated transaminases, significant hepatic pathology could still be found in cases with persistently normal transaminases. Liver biopsy in cases of chronic hepatitis B virus infection is helpful to accurately assess both the activity of the disease and the degree of fibrosis, and to estimate if antiviral therapy is justifiable. Patients with normal transaminases and serious hepatic necrosis, inflammation and fibrosis need proper management.     

Comparison of liver histopathology between chronic hepatitis C patients and chronic hepatitis B and C-coinfected patients

BACKGROUND: The aim of the present study was to compare the histological characteristics of livers between chronic hepatitis C (CHC) patients with and without hepatitis B virus (HBV) coinfection. METHODS: A total of 336 CHC patients (male/female: 204/132, mean age: 46.1 +/- 11.7 years) were enrolled in the study; 32 patients (9.8%) were positive for hepatitis B surface antigen (HBsAg). The histological characteristics of livers were described according to the Knodell and Scheuer scoring system. RESULTS: The proportion of non-intralobular necrosis (score 0) was significantly lower and the mean intralobular necrosis score was higher among CHC patients with HBV coinfection than those without coinfection (43.8% vs 64.5%; 0.84 +/- 1.05 vs 0.53 +/- 0.89). The epidemiological and virological parameters, and other histological scores (periportal necrosis, portal inflammation, total necroinflammation and fibrosis) were not significantly different between these two groups. CONCLUSION: Chronic hepatitis C patients with HBV coinfection tend to have more severe intralobular necrosis than those with isolated HCV infection.     

Diagnostic accuracy of serum biochemical fibrosis markers in children with chronic hepatitis B evaluated by receiver operating characteristics analysis

AIM: To investigate the diagnostic accuracy of potent serum biochemical fibrosis markers in children with chronic hepatitis B evaluated by receiver operating characteristics (ROC) analysis. METHODS: We determined the serum level of apolipoprotein A-I (APO A-I), haptoglobin (HPT) and a-2 macroglobulin (A2M) with an automatic nephelometer in 63 children (age range 4-17 years, mean 10 years) with biopsy-verified chronic HBeAg-positive hepatitis B. Fibrosis stage and inflammation grade were assessed in a blinded fashion according to Batts and Ludwig. We defined mild liver fibrosis as a score ≤2 and advanced fibrosis as a score equal to 3. ROC analysis was used to calculate the power of the assays to detect advanced liver fibrosis (AccuROC, Canada). RESULTS: Serum concentrations of APO A-I, HPT and A2M were not significantly different in patients with chronic hepatitis B compared to controls. However, APO A-I level of 1.19 ng/L had a sensitivity of 85.7% and a specificity of 60.7% (AUC = 0.7117, P = 0.035) to predict advanced fibrosis. All other serum biochemical markers and their combination did not allow a useful prediction. None of these markers was a good predictor of histologic inflammation. CONCLUSION: Apolipoprotein A-I may be a suitable serum marker to predict advanced liver fibrosis in children with chronic hepatitis B.     

The application of a numerical scoring system for evaluating the histological outcome in patients with chronic hepatitis B followed in long-term

A numerical scoring system was applied and compared with conventional histological classification to assess the histological outcome in 42 patients with chronic hepatitis B followed for 16 to 162 months (mean = 75 months). Four histological categories in the biopsies were assessed and scored: (i) piecemeal necrosis; (ii) lobular necrosis; (iii) portal inflammation, and (iv) fibrosis and cirrhosis. The sum of all four categories was defined as the "Histological Activity Index." Altogether, 102 liver specimens, including 2 to 4 repeats from each patient, were investigated. A good correlation was noted between a high value of the Histological Activity Index score and several liver histology as monitored by conventional terminology for chronic hepatitis. Among patients with HBeAg persistence, 8 of 14 (57%) deteriorated during follow-up as judged by an increase in the Histological Activity Index score compared to 3 of 13 (23%) of the patients with HBeAg seroconversion (0.5 less than p less than 0.1). Piecemeal necrosis has been postulated to be a predictive marker for the eventual development of cirrhosis. Here, we found that a low score for piecemeal necrosis in the initial liver biopsy was significantly less predictive of a high fibrosis score in the follow-up biopsy than was a high score for initial piecemeal necrosis (p less than 0.001). It is concluded that the scoring system used can be applied to monitor the histological long-term follow-up, especially when separated into its four constituent categories. It also offers a means of predicting a chronic hepatitis outcome.     

Application of a numerical scoring system for assessment of histological outcome in patients with chronic posttransfusion non-A, non-B hepatitis with or without antibodies to hepatitis C

A numerical scoring system was applied and compared to the conventional histological classification to assess the histological status of liver specimens from 37 patients with chronic posttransfusion non-A, non-B hepatitis followed for 7 to 105 months (mean 35 months). Four histological categories of alterations were assessed and scored: piecemeal necrosis (PMN), fibrosis and cirrhosis, lobular necrosis and portal inflammation. Sequential liver biopsies were obtained from 19 patients. PMN was generally mild but still predictive of progressing fibrosis. Thus, in none of the biopsies from four patients with initial PMN score 0 was there any increase in the fibrosis score in the follow-up biopsy, while in 10/15 (67%) patients with an initial PMN score of greater than or equal to 1 the fibrosis score increased with time (p = 0.033). Lobular necrosis and portal inflammation were not predictive of progressing fibrosis. Judging from the scoring method, 22% of all the 37 patients displayed cirrhosis and 27% bridging fibrosis in the latest liver biopsy performed. Patients with antibodies to hepatitis C did not differ in histological status or outcome from those without antibodies to hepatitis C. It is concluded that the scoring system can be used to monitor the histological long-term follow-up in patients with chronic posttransfusion non-A, non-B hepatitis, and offers a means of predicting the histological outcome.     

肝活检对转氨酶正常的慢性乙型肝炎感染的临床意义

目的探讨肝活检组织学对转氨酶持续正常6个月以上的慢性乙型肝炎(CHB)感染的临床意义.方法共452例乙型肝炎病毒(HBV)慢性感染患者接受快速经皮肝穿刺,全部病例血清HB-sAg均为阳性,病程超过6个月.肝组织切片由病理科医生盲法进行阅片.结果所有患者肝组织学显示肝内均有炎症、坏死存在.血清转氨酶异常组的炎症分级(G)和纤维化分期(C)均较转氨酶正常组严重(P＜0.05),但在后一组中,HBeAg阳性和阴性组中仍分别有10例(5.5%)和13例(9.1%)为G3,分别有7例(3.8%)和16例(11.1%)为S3,分别有3例(1.6%)和7例(4.9%)为S4.在转氨酶正常病例中,HBeAg阴性组纤维化程度较HBeAg阳性组严重(P＜0.05).如将HBeAg阳性组和阴性组合并统计,则在转氨酶正常者中,有14.6%的患者肝炎症坏死分级为G3,有21.4%为S3和S4.结论虽然严重肝病理改变多见于转氨酶异常的HBV慢性感染,但也有不少转氨酶正常病例肝呈现明显组织学异常.肝活检可作为判断肝病活动性、纤维化程度和抗病毒治疗的根据.在转氨酶正常的病例,如果肝炎症坏死-纤维化较严重,进行适当的处理看来是必要的.     

慢性HBV感染者血清HBeAg、HBV DNA载量与肝组织病理损伤的关系

目的对比不同年龄阶段乙型肝炎e抗原（HBeAg）阳性及HBeAg阴性慢性乙型肝炎病毒（HBV）感染者的肝脏病理特点。方法 323例慢性HBV感染者分为HBeAg阳性组与HBeAg阴性组,每组以40岁为界分为高龄组与低龄组,均经肝穿刺活组织检查,同时检测血清丙氨酸氨基转移酶（ALT）、HBV DNA,分析HBeAg阳性与HBeAg阴性患者高龄组与低龄组的肝脏病理损伤与血清ALT及HBV DNA水平的关系。结果 HBeAg阳性高龄组与HBeAg阴性高龄组比较具有更明显的炎症程度（P〈0.05）及更高的HBV DNA载量（P〈0.01）,HBeAg阳性低龄组与HBeAg阴性低龄组比较HBV DNA载量较高（P〈0.01）,但炎症程度无明显差异（P〉0.05）。HBeAg阴性非活动性HBV携带者与HBeAg阴性慢性乙型肝炎患者肝脏病理炎症、纤维化程度及血清HBV DNA水平在高龄组差异有统计学意义（P〈0.01）,而在低龄组差异无统计学意义。结论慢性HBV感染者血清HBeAg表达和HBV DNA水平与肝组织病理炎症分级的关系在不同年龄阶段表现不同,血清HBeAg表达与否和HBV DNA水平高低不能单独作为判断肝组织病理变化程度的指标。
