Clinical significance of serum 7S collagen in various liver diseases

Serum type IV collagen fragment (7S collagen domain) was measured in 30 controls and 152 liver disease patients with a radioimmunoassay using a polyclonal antibody to human placenta 7S collagen. The serum concentrations of 7S collagen (mean +/- SD) were 4.2 +/- 0.9 ng/mL in controls, 5.1 +/- 2.0 ng/mL in acute hepatitis, 6.5 +/- 2.5 ng/mL in chronic inactive hepatitis, 9.5 +/- 3.8 ng/mL in chronic active hepatitis, 14.4 +/- 7.5 ng/mL in liver cirrhosis, and 14.4 +/- 6.9 ng/mL in hepatocellular carcinoma. In acute hepatitis, 7S collagen was slightly increased, whereas type III procollagen N-peptide and prolyl hydroxylase were markedly increased. In chronic liver disease, 7S collagen concentrations increased with the severity of the disease, and also reflected the degree of fibrosis. The serum 7S collagen concentrations were significantly correlated with those of type III procollagen N-peptide and prolyl hydroxylase in all subjects. These results suggest that serum 7S collagen concentration is a useful diagnostic aid for determining hepatic collagen metabolism in liver diseases.     

慢性肝病患者血清腺苷脱氨酶测定的临床意义

目的探讨腺苷脱氨酶（ADA）在慢性乙型肝炎中的应用价值。方法应用OLYMPUS AU640全自动生化分析仪检测ADA及各项肝功能指标,放射免疫法检测肝纤维化指标,对其中36例患者做肝活组织检查。结果从慢性乙型肝炎病毒携带者、轻度慢性肝炎、重度慢性肝炎至肝硬化,患者血清ADA水平逐渐升高（p=0．000）。在行肝活组织检查的36例患者中,肝硬化患者ADA水平也高于慢性肝炎患者（P=0．0t6）。血清ADA与血清门天冬氨酸氨基转移酶（AST）、球蛋白、门静脉宽度、脾脏厚度、Ⅲ型前胶原（PCm）呈明显正相关（r=0．391,P=0．000;r=0．261,P=0．000;r=0．336,P=0．002;r=0．611,P=0．000;r=0．391,P=0．000）,与白蛋白、胆碱酯酶（ChE）呈明显负相关（r=-0．352,P=0．000;r=-0．200,P=0．005）。结论血清ADA水平随乙型肝炎的病情进展逐渐升高,能较好地反映肝脏的储备功能,并在一定程度上体现肝纤维化的活动情况。     

Serum hyaluronate and type III procollagen aminoterminal propeptide concentration in chronic liver disease. Relationship to cirrhosis and disease activity

To analyse the relationship between the presence of liver cirrhosis and hepatic inflammation and the serum concentrations of the aminoterminal propeptide of procollagen type III (P-III-NP) and of hyaluronic acid (HA) in chronic liver disease, we measured P-III-NP and HA concentrations in paired serum samples from 133 patients with various chronic liver diseases, from 22 patients with acute hepatitis and from 50 healthy age-matched controls. In 24 (of the 133) patients with autoimmune chronic liver disease, follow-up determination was performed during therapeutic treatment with immunosuppressive drugs. Compared with controls P-III-NP concentrations (medians) were significantly elevated in 65% of patients with chronic active hepatitis (P = 0.00097) and in 79% of patients with active liver cirrhosis (P = 0.0126) but not in patients with chronic persistent hepatitis (P = 0.06). Serum concentrations (medians) of HA were increased (P = 0.0058) in 32% of patients with chronic active hepatitis and in 91% of patients with active cirrhosis (P less than 6 x 10(-7)). The difference of HA serum concentrations but not that of P-III-NP serum concentrations in patients with chronic active hepatitis and in patients with active cirrhosis was statistically significant. HA and P-III-NP serum concentrations were significantly elevated in 22 patients with acute hepatitis.(ABSTRACT TRUNCATED AT 250 WORDS)

Fibrotic process and drug metabolism in alcoholic liver disease

The effect of fibrosis on drug metabolism in alcoholic liver disease was evaluated in a comparison of the concentrations of serum aminoterminal propeptide of type III procollagen and basement membrane (BM; 7S domain of type IV collagen and laminin) antigens with in vitro (cytochrome P-450) and in vivo (antipyrine) drug metabolism in 67 alcoholics classified by liver histology. Alcoholics with intact or fatty liver had rapid or normal drug metabolism and normal collagen metabolism. Alcoholics with a fatty liver plus fibrosis or active cirrhosis had reduced drug metabolism and elevated levels of serum markers for collagen and BM metabolism. Alcoholics with inactive cirrhosis who had received therapy with enzyme inducers had a tendency toward normal drug and collagen metabolism parameters. Antipyrine metabolism, but not P-450 content, was related to the levels of serum type III collagen and BM markers. The fibrotic process, especially BM formation, creates a mechanical barrier that may prevent contact between blood and hepatocytes, thus delaying substrate availability.     

血清尾加压素Ⅱ在3种肝脏疾病中的临床应用价值

目的探讨血清尾加压素Ⅱ(UⅡ)在慢性肝炎、肝纤维化、肝硬化病程发展中的变化及临床应用价值。方法酶联免疫吸附实验(ELISA)测定40例慢性乙型肝炎、47例肝纤维化、38例肝硬化和30例健康对照者血清中的UⅡ水平。自动分析仪检测血清天门冬氨酸氨基转移酶(AST)、丙氨酸氨基转移酶(ALT)、总胆红素(TBIL)浓度。聚合酶链反应(PCR)诊断系统检测乙型肝炎病毒基因(HBV-DNA)。各患者组与健康对照组之间的比对采用方差分析。结果与健康对照组相比,血清UⅡ水平在各组患者中均表达升高(P<0.05),其中UⅡ水平在肝纤维化组升高高于慢乙型肝炎组(P<0.05),肝硬化组高于肝纤维化组(P<0.05)。血清UⅡ水平与透明质酸(HA)、Ⅳ型胶原蛋白(C-Ⅳ)、层黏蛋白(LN)、AST、ALT水平呈正相关性(r=0.784、0.473、0.355、0.776、0.653,P=0.017、0.026、0.035、0.012、P<0.01)。血清UⅡ水平与HBV-DNA复制水平呈正相关性(r=0.571,P=0.023)。结论血清UⅡ水平在慢性HBV相关性肝病,尤其是乙型肝炎肝纤维化中表达明显升高,UⅡ检测对协助诊断及监测早期肝纤维化具有积极的临床意义。     

Type III procollagen peptide and PZ-peptidase serum levels in pre-cirrhotic liver diseases

To obtain a dynamic and non-invasive picture of hepatic fibrosis in pre-cirrhotic liver diseases we measured both the concentration of the N-terminal peptide of procollagen III, as a marker of collagen synthesis, and the activity of PZ-peptidase, an enzyme involved in collagen degradation, in the serum of alcoholic or chronic viral hepatitis patients. Peptide serum levels were similar in chronic persistent hepatitis and controls, but significantly higher in chronic active hepatitis. Chronic persistent hepatitis patients had PZ-peptidase levels higher than controls, but similar to chronic active hepatitis. The increase in collagen synthesis without a parallel increase in collagen degradation seen in chronic active hepatitis could be regarded as a sign of impending cirrhosis, whereas the unbalanced rise in PZ-peptidase observed in chronic persistent hepatitis is consistent with the non-progressive character of this disorder. In alcoholic hepatitis both peptide concentration and PZ-peptidase activity were elevated, thus suggesting that both collagen synthesis and degradation are activated. However, the greater increase in PZ-peptidase than in peptide serum levels seen in some patients seems to indicate a minor tendency to progressive fibrosis or a trend towards resolution. Unlike liver disease patients, normal peptide and PZ-peptidase levels were found in patients with pancreatic fibrosis. Since circulating inhibitors and activators of the PZ-peptidase activity can be excluded, as proved by this study, joint peptide and PZ-peptidase serum measurements would seem to offer a simple reliable non-invasive method for differentiating and monitoring progressive and non-progressive forms of hepatic fibrosis.     

慢性肝炎患者乙型肝炎病毒复制与肝纤维化标志物的关系

目的研究慢性乙型肝炎（下称乙肝）患者血清乙肝病毒（HBV）复制水平与肝纤维化血清标志物的关系。方法选择150例临床确诊为慢性乙肝的50例早期肝硬化患者，采用荧光定量聚合酶链反应（FQ-PCR）检测血清HBVDNA水平，放射免疫法和酶免疫法检测肝纤维化血清标志物（透明质酸、层黏连蛋白、Ⅲ型前胶原和Ⅳ型胶原），对血清HBVDNA水平与肝纤维化标志物的关系进行分析，并与100例无肝硬化患者血清HBVDNA及肝纤维化标志物水平进行比较。结果慢性乙肝患者血清HBVDNA水平与肝纤维化标志物的关系无统计学意义（P〉0．05），早期肝硬化患者血清肝纤维化标志物水平显著高于无肝硬化患者，但HBVDNA水平却低于无肝硬化患者（P〈0．05）。结论慢性乙肝患者血清HBVDNA水平与肝纤维化标志物水平无显著相关性。     

Biochemical markers of hepatic fibrosis in primary biliary cirrhosis

Summary We studied the behavior of some biochemical markers of fibrosis, the aminoterminal propeptide of type III procollagen (P-III-P), laminin, hyaluronate and fibronectin, in the sera of patients with primary biliary cirrhosis (PBC). Significant increases were found in serum laminin, hyaluronate and P-III-P and, more important, a significant correlation was found between the histological stage of the disease and serum hyaluronate. This parameter seems to distinguish between early PBC (I and II stages) and advanced disease with fibrosis. Moreover, a correlation between the histological stage and serum levels of both laminin and P-III-P was observed. Serum laminin, however, increases particularly in advanced disease, whereas high levels of sP-III-P are already present in the early stage. Finally, no significant differences were found between the plasma fibronectin levels of patients with primary biliary cirrhosis and those of controls.     

TIMP-1在肝纤维化组织中的表达和外周血浓度与肝病理分级的相关性研究

目的探讨慢性乙型肝炎、乙型肝炎后肝硬化患者肝组织及血清中基质金属蛋白酶抑制因子-1(tissue inhibitors of metalloproteinase,TIMP-1)与肝脏炎症活动程度及纤维化程度的相关性.方法同步收集28例慢性乙型肝炎、乙型肝炎后肝硬化患者血清及肝穿刺活组织标本,用免疫组化法测定肝纤维化组织中TIMP-1阳性率,用ELISA法检测血清中TIMP-1水平;另对47例同时期肝功能正常的健康体检者用ELISA法检测血清TIMP-1作为对照组.结果慢性乙型肝炎、乙型肝炎后肝硬化患者肝组织中TIMP-1的阳性表达与肝纤维化程度呈正相关(r=0.386,P=0.042),血清TIMP-1与肝纤维化程度呈正相关(r=0.646,P=0.000),血清中TIMP-1与肝脏炎症活动度分级呈正相关(r=0.622, P=0.000);血清TIMP-1水平与肝组织中的TIMP-1表达无显著相关性(P>0.05).结论肝活检免疫组化检测TIMP-1对反映肝纤维化程度有重要意义;血清TIMP-1含量能间接反映慢性活动性肝炎肝脏损伤程度,对于诊断及预后判断有重要参考作用.     

Type IV collagen and laminin-related antigens in human serum in alcoholic liver disease

The two major constituents of basement membranes are type IV collagen and laminin. Specific radioimmunoassays are described here for two structural domains of these proteins (7-S collagen and the fragment P1, respectively) that allow the related antigens to be quantified in human serum. The serum 7-S collagen antigen was uniform in size, whereas the laminin P1 antigenicity was heterogeneous. These proteins were measured in sera from sixty-three alcoholics, divided on the basis of liver histology into four groups: normal light microscopy, fatty liver, alcoholic cirrhosis with hepatitis and inactive cirrhosis. The group with cirrhosis and hepatitis had clearly elevated values in both assays, differing significantly from the others. A few pathological results were also seen in the other groups. The increases noted in 7-S collagen concentration were larger than those in laminin P1. During follow-up of a patient with cirrhosis and hepatitis the 7-S collagen level in particular seemed to reflect the course of the disease. The elevated basement membrane protein concentrations in serum may be associated with the formation of real basement membranes in the perisinusoidal space, a process known as capillarization of the sinusoids which is found during the development of liver cirrhosis.     

Three serum markers of collagen biosynthesis in Nigerians with cirrhosis and various infectious diseases

Serum immunoreactive prolyl hydroxylase protein, galactosylhydroxylysyl glucosyltransferase activity, and the aminoterminal propeptide of type III procollagen (S-Pro(III)-N-P) were measured in twenty patients with cirrhosis and ninety with various infectious diseases, and the values were compared with those in sixty apparently healthy Nigerians. The means for all three markers were elevated significantly in the patients with cirrhosis (P less than 0.001), acute viral hepatitis (P less than 0.001), amoebic liver abscess (P less than 0.001) and the early stages of Schistosoma mansoni infection (P less than 0.001 for S-Pro(III)-N-P, P less than 0.005 for the two other markers). The mean S-Pro(III)-N-P was also distinctly elevated during the early stages of Schistosoma haematobium infection (P less than 0.01) and filariasis (P less than 0.001), whereas none of the three markers was elevated during an acute attack of malaria. Significant correlations were found between the values for the three markers within the groups of patients with cirrhosis, amoebic liver abscess and schistosomiasis, the correlations for the pooled group of all patients being highly significant (P less than 0.001). The data suggest that elevated hepatic collagen formation is found not only in cirrhosis but also in several infectious diseases. The three serum markers may be useful for showing the stages of active collagen formation in various liver diseases and for predicting the development of fibrosis in acute cases if the values remain elevated.     

外周血中胰岛素生长因子检测与肝病的相关性研究

目的探讨肝病患者外周血中胰岛素生长因子-Ⅰ(IGF-Ⅰ)和IGF-Ⅱ水平与肝病的相关性及其检测意义。方法应用酶联免疫吸附法(ELISA)定量测定各组肝病患者血清IGF-Ⅰ、IGF-Ⅱ的含量;提取外周血白细胞总RNA,以-βactin作为内参,采用实时荧光定量RT-PCR技术测定各组IGF-ⅡmRNA表达;并采用放射免疫法检测各组血清中透明质酸(HA)和Ⅲ型前胶原(PCⅢ)的含量。结果 (1)慢性病毒性肝炎轻、中度组血清IGF-Ⅰ水平明显高于对照组(P<0.05);慢性重度肝炎组、静止型肝硬化组、活动型肝硬化组及原发性肝癌组血清IGF-Ⅰ水平均明显低于对照组和慢性轻、中度肝炎组(P<0.05)。活动性肝硬化组血清IGF-Ⅱ水平明显高于对照组、静止性肝硬化组和慢性肝炎组(P<0.05);原发性肝癌组血清IGF-Ⅱ水平明显高于各组(P<0.05)。(2)活动型肝硬化组、原发性肝癌组外周血IGF-ⅡmRNA表达均较对照组明显增高(P<0.05)。(3)慢性重度肝炎组、肝硬化组及原发性肝癌组HA和PCⅢ含量逐渐升高(P<0.05)。结论外周血中细胞因子IGF-Ⅰ水平与肝病患者肝纤维化程度密切相关,可作为反映肝细胞损伤程度的指标,并对肝病病情的估测有一定意义;肝病患者外周血中IGF-Ⅱ可能是导致肝癌的重要原因之一,当肝病患者外周血中IGF-Ⅱ水平异常增高或过量表达时要警惕肝癌的发生。     

Serum procollagen type III peptide in chronic hepatitis B

The clinical significance of serum procollagen type III peptide, a marker of active fibrogenesis, was evaluated in 110 hepatitis B surface antigen positive patients with chronic hepatitis (32 chronic persistent hepatitis, 60 chronic active hepatitis, and 18 active cirrhosis), selected on the basis of active viral replication and biochemical activity, including 54 cases treated with interferon-α. At presentation the procollagen type III peptide level serum was above normal in 48 (44%) of the 110 patients and the median value was significantly higher than that of healthy carriers with normal transaminases and histology (P<0.000005). Semiquantitative histological evaluation showed a significant correlation between serum procollagen type III peptide levels and necrosis/inflammation in the subgroup of patients with chronic active hepatitis, but no relationship with the score of fibrosis. Among patients treated with interferon-α and with increased fibrogenic activity (indicated by high pretreatment serum levels of procollagen type III peptide), peptide levels were significantly decreased when pretreatment levels were compared with those at 12 months after therapy withdrawal, both in responders to interferon (P=0.022) and non-responders (P=0.012). However, serum procollagen type III peptide levels normalized in 75% of responders to interferon with sustained serological and histological remission of liver disease, but in only 21% of non-responders (P=0.02). These results obtained in a well-defined population suggest that serum procollage type III peptide is a better marker of active fibrogenesis and inflammation than an indicator of the extent of fibrosis, and that interferon may reduce active liver fibrogenesis in chronic hepatitis B indenpendently of its effect on viral replication. However, a consistent proportion (56%) of our chronic hepatitis B patients had normal serum procollagen type III peptide levels at presentation, thus precluding the clinical use of this marker both for diagnosis of liver injury and for monitoring the therapeutic response to interferon.     

Collagen peptidase and type III procollagen peptide serum levels in chronic liver diseases.

The concentration of the N-terminal peptide of procollagen III and the activity of collagen peptidase (PZ-peptidase) were measured in sera from 92 patients with chronic liver disease. In patients with liver cirrhosis and chronic hepatitis with transformation of liver structure, high values were found for both variables compared with hepatoses and chronic hepatitis without transformation. The concentration of procollagen III peptide and the activity of collagen peptidase in serum increased with increasing degrees of fibrosis and, even more markedly, with increasing degrees of mesenchymal activity in the liver.

Evaluation of serum aminoterminal procollagen type III propeptide as an index of portal hypertension and esophageal varices in chronic liver diseases

The concentration of the aminoterminal propeptide of type III procollagen (P-III-P) was determined in serum of cubital vein and hepatic vein of patients with various types of chronic liver diseases (n = 111) and correlated with the portal venous pressure and with the degree of esophageal varices. The P-III-P level in all chronic liver diseases was correlated (rS 0.542, p less than 0.001) with the portal venous pressure, but in liver fibrotic subjects (n = 29) this correlation (rS 0.310) was not significant, in liver cirrhosis (n = 30) the respective correlation was found to be weak (rS 0.333, p less than 0.05) and similar to that in patients with unspecified chronic liver diseases (n = 52) (rS 0.425, p less than 0.01). Sensitivity and specificity of P-III-P at a cut-off concentration of 12 ng/ml for portal hypertension (portal vein pressure 5 mm Hg) are 0.93 and 0.42, respectively, the diagnostic efficiency is 0.67. Predictive values at the same cut-off level of P-III-P and an assumed prevalence of portal hypertension of 50% are 0.62 and 0.85 for the positive and negative test result, respectively. The level of P-III-P is not related to the degree of esophageal varices. The mean P-III-P concentration in the hepatic vein was found to be significantly (p less than 0.001) higher (about 35%) than that in the cubital vein. It is concluded that P-III-P is not an useful parameter for diagnosis of portal hypertension and monitoring of portal vein pressure and of the degree of esophageal varices.     

慢性乙型肝病患者肝组织和血清TGF-β1的测定及临床意义

目的探讨慢性乙型肝病(CLD-B)患者血清TGF-β1水平变化在反映肝脏炎症和纤维化程度的诊断意义。方法采用ELISA法检测155例CLD-B患者血清TGF-β1水平,对其中31例患者的肝穿活体组织进行原位杂交检测TGF-β1 mRNA,HE染色和Van Gieson氏胶原染色进行炎症分级和纤维化分期。结果慢性乙型肝炎(CHB)及活动性肝硬化患者血清TGF-β1水平显著高于对照组(P0.01),TGF-β1水平在活动性肝硬化最高(P0.05),而静止性肝硬化升高不明显(P0.05)。CLD-B患者血清TGF-β1分泌水平与肝组织TGF-β1 mRNA表达强度展示良好的一致性。Spearman相关分析显示:CLD-B患者血清TGF-β1水平与肝组织炎症分级及早期肝纤维化分期呈正相关(r=0.721,r=0.683,均为P0.05)。结论 CLD-B患者检测血清TGF-β1对推断肝脏炎症和早期肝纤维化的程度具有临床诊断意义。     

儿童乙型病毒性肝炎肝脏病理与肝功能、肝纤维化血清学指标的关系

【目的】探讨儿童慢性乙型病毒性肝炎的肝脏病理变化与肝功能、肝纤维化血清学指标、血清乙肝病毒的脱氧核糖核酸（HBV-DNA）载量的相关性。【方法】回顾性分析2010年7月至2015年6月本院肝病中心收治确诊的79例慢性乙型病毒性肝炎临床病理资料。收集患儿的术前3d的肝功能、肝纤维化血清学四项指标、HBV-DNA病毒栽量等检测指标。根据肝脏病理改变程度分为轻度和中重度炎症损伤两组及无肝纤维化和肝纤维化两组,分析与其血清谷丙转氨酶（ALT）、谷草转氨酶（AST）、总蛋白（Abl）、Ⅲ型胶原蛋白（PCⅢ）、层粘连蛋白（LN）、透明质酸酶（HA）、Ⅳ型胶原蛋白（Ⅳc）水平及HBV-DNA载量的关系。【结果】轻度肝脏炎症组57例,中重度肝脏炎症组22例,两组的ALT、AST、Abl及HBV-DNA载量的差异比较均无统计学意义（P〉0．05）。无肝脏纤维化组19例,肝脏纤维化组60例,两组的肝纤维四项指标发现Ⅲ型胶原蛋白、层粘连蛋白、透明质酸酶及Ⅳ型胶原蛋白差异比较具有统计学意义（P〈0．05）,但两组间的谷丙转氨酶、谷草转氨酶、白蛋白、HBV-DNA载量差异无明显统计学意义（P〉0．05）。【结论】肝功能及HBV-DNA载量不能预测儿童慢性乙型病毒性肝炎的肝脏病理炎症改变程度,肝纤维四项对评估患儿肝脏纤维化程度有一定临床意义。肝穿刺活检为评估患儿肝脏病理改变的金标准,对于指导儿童乙型病毒性肝炎的治疗具有重要作用。
