丙氨酸转氨酶正常的慢性乙型肝炎病毒感染者的肝脏病理学分析

Objective To study the liver histological changes in chronic hepaitits B (CHB) patients with normal serum alanine aminotransferase (ALT) levels and the related factors. Methods Six hundred and thirty-two CHB patients with normal ALT levels had undergone ultrasound guided percutaneous liver biopsies. All specimen were examined by HE staining, collagen fiber Masson staining and immunohistochemical staining for hepatitis B surface antigen (HBsAg) and hepatitis B core antigen (HBcAg). The Knodell inflammation score and Ishak fibrosis score were both calculated and the relationship with age, serum levels of ALT and hepatitis B virus (HBV) DNA, hepatic expressions of HBsAg and HBcAg were analyzed. The means between two groups were compared by t test and those among groups were compared by one-factor analysis of variance and q test. Enumeration data were analyzed by x2 test. Results Among 632 CHB patients with normal ALT levels, 167 (26.4%) showed moderate necrotic inflammation in liver tissues and 26 (4.1%) showed severe necrotic inflammation; 217 (34. 3 % ) showed moderate fibrosis and 52 (8. 2 % ) showed severe fibrosis (cirrhosis). The Knodell inflammation score and Ishak fibrosis score in high ALT group were higher than low ALT group, those in female high ALT group were higher than male high ALT group and those in patients ＞ 40 years old were higher than ≤20 years old (q= 19.63, P＜0. 05). The liver injuries in patients with active HBV replication were more severe than those with undetectable HBV DNA levels (Knodell score, q=3.87, 2.87, 6.34; Ishak score, q=2.64,2. 64,5.54, all P＜0. 05),while there was no significant difference between patients with high levels and low levels of HBV DNA (F= 1.35, P＞0. 05). There was no significant difference between expressions of HBsAg (F= 1.65,0. 73,respectively; both P＞0. 05) and HBcAg in liver tissues and Knodell inflammation score and Ishak fibrosis score (F=0. 17, 1.29, respectively; both P＞0. 05). Conclusions Liver biopsies should be considered in CHB patients with normal ALT levels and detectable HBV DNA levels, especially those ＞ 40 years old and with ALT of (0.75-1.00) × upper limits of normal (ULN).

Histopathological evaluation of liver biopsy specimens in children with chronic hepatitis B.

INTRODUCTION: Histopathological evaluation of the liver remains important diagnostic tool. OBJECTIVE: The aim of this study was to assess inflammatory activity, fibrosis and their correlation to the expression of viral antigens in the liver of children with chronic hepatitis B (CHB) before antiviral treatment. MATERIAL AND METHODS: The study included 190 liver biopsies of children aged 1.5-18 (mean 7.46+/-4.05 years) with CHB. The histopathological examination was based on the modified Knodell system. Additionally, immunomorphological analysis was performed in 125 specimens to detect HBsAg and HBcAg. RESULTS: Necroinflammatory activity was scored for mild in 109 children and moderate in 49. Fibrosis was scored for S1 in 90, S2 in 58 and S3-S4 in seven cases. Positive correlation between grading and staging was observed (chi(2)=77.65, p=0.000002). HBsAg was detected in 62 specimens, while HBcAg was found in the nuclei of 108 samples with cytoplasmic expression in 35-28% cases. No correlation of HBsAg expression to histopathological lesions was established whereas partial correlation of HBcAg expression with inflammatory infiltrate was confirmed. CONCLUSIONS: Progression of liver injury in children with CHB varies in severity. Necroinflammatory activity correlates with fibrosis. Expression of viral antigens is independent of histological changes, however confirms the etiology of liver disease.     

慢性乙型肝炎患者肝组织学检查的意义

目的：肝穿活检组织病理学检查是肝病诊断的“金标准”,但目前还难以普遍实施,本文主要比较临床诊断和病理学诊断的符合度。方法采取肝穿刺活检法对1100例 CHB 患者进行肝组织病理学检查,以其为金标准,判断临床诊断的准确性。结果在1100例 CHB 患者中,经病理学诊断为慢性肝炎轻度、中度和重度分别为810例、212例和78例,而临床诊断正确的分别为520例、110例和60例;对经病理学诊断明确的160例慢性乙型肝炎轻度、50例慢性肝炎中度和30例慢性乙型肝炎重度患者进行肝硬度检测,他们的肝弹性分别为（7.5±0.8） kPa、（9.2±1.2） kPa 和（15.3±3.2） kPa。结论慢性乙型肝炎的临床诊断往往仅凭经验,与肝组织病理学诊断结果存在误差,还需要研究新的无创性的诊断方法。     

Relationship between hepatitis B virus DNA levels and liver histology in patients with chronic hepatitis B

AIM： To study the relationship between hepatitis B virus （HBV） DNA levels and liver histology in patients with chronic hepatitis B （CHB） and to determine the prevalence and characteristics of hepatitis B e antigen （HBeAg） negative patients.
METHODS： A total of 213 patients with CHB were studied, and serum HBV DNA levels were measured by the COBAS Amplicor HBV Monitor test. All patients were divided into two groups according to the HBeAg status.The correlation between serum HBV DNA levels and liver damage （liver histology and biochemistry） was explored.
RESULTS： Of the 213 patients with serum HBV DNA levels higher than 10^5 copies/mL, 178 （83.6%） were HBeAg positive, 35 （16.4%） were HBeAg negative. The serum HBV DNA levels were not correlated to the age,history of CHB, histological grade and stage of liver disease in either HBeAg negative or HBeAg positive patients. There was no correlation between serum levels of HBV DNA and alanine aminotransferanse （ALT）,aspartate aminotrans-ferase （AST） in HBeAg positive patients. In HBeAg negative patients, there was no correlation between serum levels of HBV DNA and AST,while serum DNA levels correlated with ALT （r = 0.351, P = 0.042）. The grade （G） of liver disease correlated with ALT and AST （P 〈 0.05, r = 0.205, 0.327 respectively）in HBeAg positive patients. In HBeAg negative patients,correlations were shown between ALT, AST and the G （P 〈 0.01, and r = 0.862, 0.802 respectively）. HBeAg negative patients were older （35 ± 9 years vs 30 ±9 years, P 〈 0.05 ） and had a longer history of HBV infection （8 ± 4 years vs 6 ± 4 years, P 〈 0.05） and a lower HBV DNA level than HBeAg positive patients （8.4± 1.7 Log HBV DNA vs 9.8 ± 1.3 Log HBV DNA, P 〈0.001）. There were no significant differences in sex ratio,ALT and AST levels and liver histology between the two groups.
CONCLUSION： Serum HBV DNA level is not correlated to histological grade or stage of liver disease in CHB patients with HBV DNA mor     

血清胆碱酯酶和总胆汁酸与慢性乙型肝炎患者肝脏病理损害的关系探讨

目的探讨血清胆碱酯酶（CHE）、总胆汁酸（TBA）与慢性乙型肝炎肝脏病理损害的关系。方法检测303例经肝穿刺活检病理证实的慢性乙型肝炎患者血清CHE和TBA，并对其与肝活检组织病理炎症分级和纤维化分期进行相关性分析。结果随着肝脏病理炎症分级和纤维化分期的加重，血清CHE逐渐下降，而血清TBA逐渐升高。血清CHE与肝脏病理分级和分期呈显著负相关（P〈0．01），血清TBA与肝脏病理分级和分期呈显著正相关（P〈0．01）。结论临床上联合测定血清CHE和TBA可在一定程度上反映慢性乙型肝炎肝组织病理损伤的程度。     

慢性乙型肝炎患者肝组织PDGF表达与肝窦病变的关系

目的探讨慢性乙型肝炎(CHB)患者肝组织血小板衍生生长因子(PDGF)表达与肝窦病变的关系。方法采用免疫组化法检测120例CHB患者肝活检组织PDGF的表达;采用电镜技术分析CHB患者肝窦病变,并分析其表达变化与肝窦病变的关系。结果慢性乙型肝炎和肝硬化患者的肝窦病变有狭窄、阻塞、扩张、窦周隙淤血、肝窦毛细血管化等改变。PDGF的表达与病理组织学分度呈一致性改变,随着肝纤维化程度、炎症活动度和病理组织学分度的加重,PDGF在肝组织中的表达逐渐明显,且轻度与中度、重度、肝硬化组之间差异显著(P<0.01)。PDGF表达强弱与肝窦和窦周隙病变程度呈平行关系。结论PDGF表达增强可能参与了CHB患者炎症进展及肝窦和窦周隙病变的发病过程。
