原发性肝癌患者乙肝病毒感染模式及其与甲胎蛋白和肝功能的关系 总被引:1,自引:0,他引:1
目的 探讨原发性肝癌(primary hepatocellular carcinoma,PHC)患者乙型肝炎病毒(hepatitis B virus,HBV)感染模式与血清甲胎蛋白(AFP)及肝功能检查的关系.方法 采用化学发光免疫分析和ELISA法及用速率法生化分析分别检测116例PHC患者.进行了甲胎蛋白、乙型肝炎病毒五项标志物及肝功能总胆红素(TBILI)、谷丙转氨酶(ALT)、谷氨酰转肽酶(GGT)及碱性磷酸酶(ALP)血清检测.结果 116例PHC患者HBV总感染率为97.4%(113/116).HBsAg阴性为8.62%(10/116).PHC患者HBV血清标志物感染模式,以HBsAg、抗-HBe和抗HBc阳性模式(小三阳)感染类型最多.表明该模式的乙肝患者为原发性肝癌的高危人群.只有3例(2.6%)PHC无HBV感染标记.116例PHC患者AFP测定有29例(25.0%)结果阴性,87例测定结果阳性,阳性率达75.0%.116例PHC患者全部病例均行肝功能检查,原发性肝癌患者肝功能异常者有较高的发生率.肝功能损害各个指标浓度呈不同程度的增高.结论 HBV与PHC之间的关系非常明确,HBV感染不仅是肝癌发生的一个重要的危险因素,而且表明肝癌病人常伴有HBV的复制活跃.提示仍有25.0%PHC患者血清AFP检测结果呈阴性而易被漏诊.约有50%原发性肝癌患者肝功能损害.因此,积极预防和控制HBV感染流行,恰当治疗、保肝和护肝措施,是减少原发性肝癌发生的关键所在. 相似文献

Serum cytokeratin (CK) levels are widely used as tumor markers. Serum levels of CK-18, a tumor marker also known as tissue polypeptide specific antigen (TPS), are increased in patients with alcoholic liver disease. Cytokeratin-18 is the main component of Mallory bodies, a hallmark of alcoholic hepatitis, which may also contain CK-19. Serum levels of CK-18 and CK-19, a tumor marker also known as CYtokeratin FRAgment 21-1 (CYFRA 21-1) were investigated in (a) heavy drinkers with alcoholic liver disease (n=15), (b) patients with malignancy (n=22), and (c) healthy controls (n=10). Serum levels of CYFRA 21-1 (CK-19) were markedly increased in patients with malignancy, but were similar in heavy drinkers and healthy controls. In contrast, serum levels of TPS (CK-18) in heavy drinkers were higher than those of healthy controls, and even tended to be higher than those of patients with malignancy. Both CK-19 and CK-18 levels were higher in cases of alcoholic hepatitis than in cases of fatty liver. Correlation with hepatocyte CK inclusions was stronger for serum TPS (CK-18) than for CYFRA 21-1 (CK-19). In conclusion, serum CYFRA 21-1 (CK-19) and TPS (CK-18) show a different pattern of increase that could reflect the composition of the altered hepatocyte CK network in alcoholic liver disease. Their usefulness as tumor markers, particularly that of serum TPS (CK-18), may be limited in patients with alcoholic liver disease. 相似文献

目的探究中性粒细胞明胶酶相关脂质运载蛋白(NGAL)对脓毒症和脓毒性休克患者预后的预测作用。
方法采用回顾性病例对照研究分析上海交通大学医学院附属瑞金医院急诊科2017年1月31日至2019年1月31日收治且明确诊断为脓毒症/脓毒性休克的84例患者,其中男性53例,女性31例;年龄18~80岁,平均(56.5±17.8)岁。根据患者的预后分为生生存组(n=62)和死亡组(n=22)。在患者入院第1天、第3天和第7天检测血浆NGAL水平,比较两组患者临床资料、实验室检查指标水平的差异,筛选出差异有统计学意义的观察指标对比,并采用pearson相关性分析比较NGAL与其他预后指标的相关性。再通过受试者工作特征曲线(ROC)曲线判断NGAL对脓毒症/脓毒性休克患者发生院内死亡和是否需行连续肾脏替代疗法(CRRT)治疗的预测价值。
结果死亡组患者NGAL浓度在第1天[(2 188.4±2 280.8)ng/mL比(538.2±777.4)ng/mL]、第3天[(2 045.5±2 388.8)ng/mL比(553.8±836.4)ng/mL]和第7天[(1 512.4±1 840.9)ng/mL比(192.3±410.2)ng/mL]均明显高于生存组患者,差异均有统计学意义(P<0.05)。NGAL水平与序贯器官衰竭评分(Sequential Organ Failure Assessment, SOFA)(r=0.4601)、急性生理与慢性健康评分(APACHE Ⅱ)(r=0.37)、乳酸(r=0.41)和肌酐(r=0.48)都呈正相关性(P均<0.05)。第7天时NGAL水平对预后的预测价值[曲线下面积(AUROC)=0.85,95% CI:0.70~0.99]高于第1天(AUROC=0.71,95%CI:0.55~0.88)和第3天(AUROC=0.72,95%CI:0.55~0.88)。第3天时肌酐和NGAL对是否需行CRRT的预测价值优于第1天和第7天。入院第3天时NGAL浓度(AUROC=0.80,95%CI:0.64~0.97)与肌酐水平(AUROC=0.83,95%CI:0.68~0.97)相比,前者对患者是否需行CRRT的预测作用具有更好的特异性,但敏感度相对较低。
结论对于脓毒症/脓毒性休克患者第7天时NGAL水平对预后具有很高的预测价值。与肌酐相比,NGAL对预测患者是否需行CRRT具有更高的特异性。 相似文献

Sera from 185 patients admitted to hospital in Malawi with acute and chronic liver disease were tested for the following serological markers of hepatitis-B infection (HBV): hepatitis-B surface antigen (HBsAg) and its antibody (anti-HBs), HBe antigen (HBeAg) and its antibody (anti-HBe), and antibody to hepatitis-B core antigen (anti-HBc). Control groups consisted of patients without liver disease, students and blood donors. HBsAg was detected in 73%, 54·8% and 64% of patients with acute hepatitis, cirrhosis and hepatoma, respectively. 16% of patients with tropical splenomegaly syndrome (TSS) and 14·6% of patients with schistosomiasis, 9·5% of patients without liver disease, 1·4% of students and 7·6% of blood donors were HBsAg positive. Unexpectedly, 72·3% of HBsAg-positive specimens appeared to carry both major antigenic determinants (ady). HBeAg was detected in 15·8% and anti-HBe in 13·1% of patients with acute HBsAg-associated hepatitis, these determinants being detected less frequently than in sera from patients with HBsAg-associated hepatitis in the UK. HBeAg or anti-HBe were rarely detected in patients with hepatoma. With the exception of students and blood donors, over 80% of the Malawian study population had markers of current or previous HBV infection in their sera. Anti-HBc occurred most frequently in patients with hepatitis, cirrhosis and hepatoma, their geometric mean titres (GMTs) being 67·6, 160·1 and 211, respectively. The GMTs of patients with TSS, schistosomiasis and non-hepatic disease were 2·0, 4·6 and 2·3, respectively. 相似文献

BACKGROUND: Hypermetabolism has a negative effect on prognosis in patients with liver cirrhosis. Its exact prevalence and associations with clinical data, the nutritional state, and beta-adrenergic activity are unclear. OBJECTIVE: We investigated resting energy expenditure (REE) in 473 patients with biopsy-proven liver cirrhosis. DESIGN: This was a cross-sectional study with a controlled intervention (beta-blockade) in a subgroup of patients. RESULTS: Mean REE was 7.12 +/- 1.34 MJ/d and correlated closely with predicted values (r = 0.70, P < 0.0001). Hypermetabolism was seen in 160 patients with cirrhosis (33.8% of the study population). REE was > 30% above the predicted value in 41% of the hypermetabolic patients with cirrhosis. Hypermetabolism had no association with clinical or biochemical data on liver function. REE correlated with total body potassium content (TBP; r = 0.49, P < 0.0001). Hypermetabolic patients had lower than normal body weight and TBP (P < 0.05). About 47% of the variance in REE could be explained by body composition whereas clinical state could maximally explain 3%. Plasma epinephrine and norepinephrine concentrations were elevated in hypermetabolic cirrhotic patients (by 56% and 41%, respectively; P < 0.001 and 0.01). Differences in REE from predicted values were positively correlated with epinephrine concentration (r = 0.462, P < 0.001). Propranolol infusion resulted in a decrease in energy expenditure (by 5 +/- 3%; P < 0.05), heart rate (by 13 +/- 4%; P < 0.01), and plasma lactate concentrations (by 32 +/- 12%; P < 0.01); these effects were more pronounced in hypermetabolic patients (by 50%, 33%, and 68%, respectively; each P < 0.05). CONCLUSIONS: Hypermetabolism has no association with clinical data and thus is an extrahepatic manifestation of liver disease. Increased beta-adrenergic activity may explain approximately 25% of hypermetabolism. 相似文献

The prevalence of hepatitis B surface antigen (HBsAg), antibody to the hepatitis B core (anti-HBc) and to surface antigen (anti-HBs), was investigated, using sensitive radioimmunoassay (RIA) systems, among patients with different clinical entities of chronic liver disease in Kuwait, and compared to a control blood donor population. 81% of patients and 44% of the controls had at least one HBV marker. 24% of patients, but none of the controls had both HBsAg and a high titre of anti-HBc in the absence of anti-HBs, suggesting a chronic infection. 31% of our patients with hepatosplenic schistosomiasis, 20% with cryptogenic cirrhosis and chronic active liver disease and 60% with hepatocellular carcinoma had these two markers. HBV antigenaemia was significantly more prevalent among male than among female patients and was particularly high among those less than 35 years old. The high prevalence of the various HBV markers among our patients suggests that HBV is a major factor in the development of chronic liver disease in our area. Furthermore, in view of the high prevalence of antigenaemia in patients with hepatosplenic schistosomiasis, HBV infection must play a concomitant role in the development of a more serious form of chronic liver disease among such patients. 相似文献

During the past 15 years, a growing body of evidence incriminates hepatitis B virus as the major factor in the etiology of primary liver cancer. Epidemiological studies throughout the world reported a striking correspondence between areas where the frequency of primary liver cancer is high and where HBV infection is hyperendemic. Moreover, primary liver cancer is commonly associated with cirrhosis of the postnecrotic macronodular type. Such data suggested a sequence hepatitis-cirrhosis-PLC. Such sequence was confirmed by extensive serologic testing studies which reported a high frequency of HBV markers in PLC patients compared to matched control groups. Data collected in Senegal, Mali and Burundi on 12,000 individuals stress the importance of HBV infections in these countries, as the high rate of chronic carrier state in patients suffering from liver cirrhosis or primary liver cancer (62-63%) compared to the general population (12-17%). Other HBV markers including anti-HBs, anti-HBc, HBeAg and anti-HBe had no prognostic value in the sequence hepatitis-cirrhosis-PLC. A new HBV seric marker, the HBsAg/IgM complexes, observed in HBsAg positive individuals, is more frequently detected in PLC patients (50%) and cirrhosis (40%) than in healthy HBsAg carriers (14%). These results would indicate that HBsAg carriers are more likely to develop cirrhosis or primary liver cancer when they evidence HBsAg/IgM complexes. In conclusion, the seric markers of evolution towards primary liver cancer are: HBsAg (the highest known risk factor), the presence in such individuals of HBsAg/IgM complexes, and increased values of alphafoetoprotein. 相似文献

Blood cell superoxide dismutase and enolase activities as markers of alcoholic and nonalcoholic liver diseases 总被引:1,自引:0,他引:1
Monitoring of chronic alcoholism would be facilitated by using sensitive biochemical markers in blood cells, mainly to detect differences between alcoholic subjects with or without liver injury. We propose two types of markers: the first one is superoxide dismutase (SOD) activity involved in the conversion of superoxide radicals (O2-.) formed during acetaldehyde oxidation by xanthine oxidase after chronic alcohol consumption; the second one is enolase activity with both isoenzyme forms: nonneuronal enolase (NNE) and neuron specific enolase (NSE) which has been shown to be modified in many injuries related to the glycolytic pathways. For SOD activity we found a significant increase in alcoholic patients with liver injury and mainly in cirrhotic patients with ascitis. Both enolase activities were also found to be significantly increased in alcoholic patients with liver injury but NNE activity was also increased in alcoholics without apparent liver disease. Our results suggest that increased activity of SOD and NSE in blood cells may be related to liver injury mainly in alcoholism while increased NNE activity may also be a marker of alcohol abuse without liver injury. 相似文献

A prospective study was conducted on liver disease patients without previous history of bleeding (haematemesis and/or melena) to identify those at highest risk of bleeding. A hundred and twenty non-alcoholic patients (96 males and 24 females), ages ranging from 30 to 60 years were studied. Patients were followed for up to two years or to time of bleeding (mean 18 +/- 7.3 months), during which 34 (28.3%) patients bled. Schistosomal patients showed less incidence of bleeding (12.1%, p < 0.05) than those with mixed aetiology (Schistosoma and cirrhosis 23.5%, and chronic active hepatitis and schistosoma 44.4%). The presence of positive viral markers (either HCV antibodies or HBsAg) was associated with a higher percent of bleeding during the follow-up period (43.2% and 45.4%, respectively), than those negative for these markers (21.7%, 24.4%, respectively). Univariate analysis showed the following significant risk factors associated with bleeding: modified child classification, reduced platelet count, endoscopic findings of cherry red spots, gastric varices and increased grade of oesophageal varices. Multivariate analysis revealed that the risk of bleeding was significantly related to the presence of cherry red spots, the presence of gastric varices, grade of oesophageal varices and the patient's prothrombin time. In conclusion, bleeding from oesophageal varices is a frequent and serious event in patients with chronic liver disease. The risk of variceal bleeding from liver disease with mixed aetiology (schistosomiasis associated with viral hepatitis HBV or HCV) was found to be significantly higher than that with schistosomal aetiology alone. The endoscopic findings of cherry red spots, gastric varices, increased grade of oesophageal varices and to a lesser extent the prothrombin time were found to be high risk factors. Patients having those risk factors should be considered for prophylactic measures. 相似文献
