[PMID: 29113391 PMCID: PMC5655286 DOI: 10.18632/oncotarget.18466] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/09/2017] [Accepted: 04/18/2017] [Indexed: 02/07/2023] Open
Abstract
Background The link between the subcategories of liver cirrhosis and type 2 diabetes is not well known. We investigated the association of type 2 diabetes mellitus with alcoholic cirrhosis and cirrhosis without alcohol. Methods This nationwide cohort study used the Taiwan National Health Insurance Research Database. Cirrhotic individuals and their matched controls were identified from 2001-2008. In all, 9 313 cirrhotic patients aged 20 years or older were matched by age, sex, and index date with the non-cirrhotic individuals (n = 37 252). Cirrhosis was categorized into alcoholic cirrhosis and cirrhosis without alcohol. Type 2 diabetes mellitus was identified from January 2001- December 2011. Results The incidence densities (per 1 000 person-months) of type 2 diabetes were as follows: 1.14 (95% CI: 1.09-1.20) in the non-cirrhotic group, 1.88 (CI 1.76-2.01) in patients with cirrhosis, 1.62 (CI 1.48-1.78) in patients with cirrhosis without alcohol, and 2.92 (CI 2.64-3.23) in patients with alcoholic cirrhosis. The adjusted hazards ratio (aHR) for type 2 diabetes mellitus among cirrhotic individuals was 0.774 (CI: 0.715-0.8934). Alcoholic cirrhotic men had a significantly higher risk of type 2 diabetes (aHR 1.182, CI: 1.046-1.335) compared with non-cirrhotic individuals. Increased risks were seen in men (aHR 1.690; CI: 1.455-1.963) and women (aHR 1.715; CI: 1.113-2.645) with alcoholic cirrhosis compared to those with cirrhosis without alcohol. Conclusions This study indicates that alcoholic cirrhosis is a significant risk factor for type 2 diabetes mellitus compared with cirrhosis without alcohol.

Abstract
This case-control study aimed to assess the interactive effect between polymorphisms of lymphotoxin (LT) α +252 and habitual substance use on risk of hepatocellular carcinoma (HCC). We enrolled 150 pairs of sex- and age-matched HCC patients and unrelated healthy controls. LTα genotypes were detected with polymerase-chain reaction and restrictive fragment length polymorphisms. Information about habits of substance use was obtained through personal interview. Multivariate analysis indicated that LTα +252 G/G genotypes [odds ratio (OR) = 3.36], Hepatitis B surface antigen (OR = 16.68), antibodies to hepatitis C virus (OR = 34.88) and having at least two habits of substance use (OR = 2.50) were independent risk factors for HCC. There were additive interactions among LTα +252 G/G genotype, chronic viral hepatitis, and habit of each substance use. IN CONCLUSION There are independent and additive interactions between LTα +252 G/G genotype, chronic viral hepatitis, and habits of substance use on risk of HCC.

Abstract
This case-control study was aimed to assess the effect of genetic variants of tumor necrosis factor (TNF) α-308 and lymphotoxin (LT) α+252 on development of hepatitis B virus (HBV)-related hepatocellular carcinoma (HCC). Their gene-gene interaction was also investigated. We enrolled 200 pairs of age- and sex-matched patients with cirrhotic HBV-HCC and unrelated patients with HBV-cirrhosis alone. Polymorphisms of TNFα-308 and LTα+252 were genotyped. Synergy index was used to calculate interaction between the variant genotypes. The results indicated that the frequency distribution of the variant genotypes (TNFα-308 G/A and LTα+252 G/G) in patients with HCC were significantly higher than those in patients with cirrhosis alone. Multivariate analysis indicated that TNFα-308 G/A (odds ratio [OR], 2.34) and LTα+252 G/G (OR, 2.04) were independent risk factors for HCC. By the clinical characteristics of study population, multivariate analysis demonstrated that independent factors associated with harboring the variant genotypes included cirrhosis with Child-Pugh C (OR = 6.47 in cases and OR = 11.56 in controls) and thrombocytopenia (OR = 8.86 in cases and OR = 7.74 in controls). Calculation of synergy index (SI) indicated that there are additive interaction between TNFα-308 G/A and LTα+252 G/G on risk of HCC (SI = 1.29). IN CONCLUSION There are independent and additive interactions between TNFα-308 G/A and LTα+252 G/G on risk for HBV-HCC. They correlated with advanced hepatic fibrosis and severe liver damage, which might contribute to a higher risk for HCC.

Abstract
BACKGROUND The aims of this study were to assess the prevalence of elevated alanine aminotransferase (ALT) and explore its related factors in Central Taiwan. METHODS The study employed a retrospective design. The study selected a sample of 5,550 subjects between the years 2000 to 2004. The indivduals undergoing health examinations in a medical center in Central Taiwan were enrolled as subjects for this research. The patients' demographics, smoking and drinking habits, laboratory findings, and abdominal ultrasound results were collected and analyzed. Correlations between variables were analyzed using SPSS/ PC Windows for frequency distribution, t-test, Chi-square test, and multivariate logistic regression. RESULTS There were 3103 men (55.9%) and 2447 women (44.1%). The mean age was 49.4 ± 12.3 years (age range of 20-87). The overall prevalence of elevated ALT was 17.1%, with a significant gender difference (23.2% in men vs. 9.4% in women, P < .0001). The multivariate logistic regression analysis showed that the factors significantly related to elevated ALT were central obesity, hypertriglyceridemia, and anti-HCV positive in men and women. CONCLUSIONS Central obesity, hypertriglyceridemia, and anti-HCV positive are factors predominantly related to elevated ALT in men and women.

Abstract
Here we found that serum levels of thioredoxin were increased in patients with hepatocellular carcinoma (HCC). The optimum diagnostic cutoff for thioredoxin was 20.5 ng/mL (area under curve [AUC] 0.946 [95% CI 0.923–0.969] in the training cohort; 0.941 [0.918–0.963] in the validation cohort). High serum concentrations of thioredoxin differentiated HCC from chronic liver diseases and cirrhosis (0.901 [0.875–0.923] in the training cohort; 0.906 [0.870–0.925] in the validation cohort). Furthermore, a higher proportion of patients with very early HCC had positive results for thioredoxin than for alpha-Fetoprotein (AFP) (73.7% VS.31.6%; P < 0.0001). Among AFP-negative patients with very early HCC, 18 (69.2%) of 26 had positive thioredoxin results. Our results indicate that serum thioredoxin complements measurement of AFP in the diagnosis of HCC, especially in very early disease. Combined model (thioredoxin and AFP) showed a significantly greater discriminatory ability as compared with those markers alone.

Abstract
INTRODUCTION Necrotising fasciitis (NF) is often found in patients with diabetes mellitus, chronic renal failure, alcoholism, malignancy or liver cirrhosis. However, it remains unknown whether liver cirrhosis is an independent risk factor for the occurrence of NF. This study aimed to determine whether liver cirrhosis is an independent risk factor for the occurrence of NF, and to identify the relationship between severity of liver cirrhosis and occurrence of NF. METHODS The National Health Insurance Research Database, maintained by Taiwan's National Health Insurance programme, was retrospectively analysed, and the hospitalisation data of 40,802 cirrhotic patients and 40,865 randomly selected, age‑ and gender‑matched non‑cirrhotic control patients was collected. The medical records of all patients were individually followed for a three‑year period from the patients' first hospitalisation in 2004. RESULTS During the three‑year follow‑up period, there were 299 (0.7%) cirrhotic patients with NF and 160 (0.4%) non‑cirrhotic patients with NF. Cox regression analysis showed that liver cirrhosis was a risk factor for the occurrence of NF during the study period (hazard ratio 1.982; p < 0.001). Among cirrhotic patients, those with complicated liver cirrhosis had a higher risk for the occurrence of NF than patients with non‑complicated liver cirrhosis (hazard ratio 1.320; p = 0.028). CONCLUSION Cirrhotic patients had a higher risk for the occurrence of NF than non‑cirrhotic patients, and the risk for NF was especially high among patients with complicated liver cirrhosis.

Abstract
The association between autoimmune diseases and liver cirrhosis has rarely been explored in Asian populations, an endemic area of viral hepatitis. The aim of this study was to investigate the comparative risk of liver cirrhosis among a group of selective autoimmune diseases in Taiwanese patients and to identify groups of high risk. This retrospective study was a nationwide, population-based study and used Taiwan's National Health Insurance Research Database. A total of 29,856 patients with definite diagnosis of selected autoimmune diseases (Registry of Taiwan Catastrophic Illness Database, ACR classification) at the starting time point of January 1, 2005, were enrolled in this study. After tracked for a 5-year period, the endpoints were diagnosis of liver cirrhosis (in accordance with International Classification of Diseases, Ninth Revision, Clinical Modification, ICD-9-CM codes 571). The control group was composed of other patients in the same database and consisted of randomly selected 753,495 sex- and age-matched non-autoimmune disease patients. The Cox proportional hazard regression model was used to calculate the risk of liver cirrhosis after adjusting for certain variables such as comorbidity, living area, and socioeconomic status. Among the patients with selected autoimmune diseases, 1987 liver cirrhosis were observed. Patients with psoriasis had a significantly increased risk of liver cirrhosis (HR 1.87, 95 % CI 1.25-2.81) than control group without psoriasis. The risk of liver cirrhosis was significantly lower in patients with rheumatoid arthritis (HR 0.29, 95 % CI 0.19-0.44). There is a gradient of risk of liver cirrhosis among the autoimmune diseases; the specific risks need to be investigated on the basis of hypotheses. Conventional immunosuppressive drug administration should be carefully implemented by regular monitoring of liver condition in order to avoid causing an adverse effect of chronic liver fibrosis.

Abstract
INTRODUCTION Due to impairment of immunity and metabolism, cirrhotic patients are prone to infection, osteoporosis, and osteonecrosis. However, it is unknown if cirrhotic patients are prone to native septic arthritis (NSA). AIM To assess the occurrence of NSA between cirrhotic and non-cirrhotic patients. MATERIAL AND METHODS We used the Taiwan National Health Insurance Database to enrol 35,106 cirrhotic patients and 33,457 non-cirrhotic patients from January 1, 2004 to December 31, 2004. The medical record of each patient was individually followed for a 3-year period. RESULTS There were 341 (0.5%) patients having NSA in a follow-up period of 3 years: 214 cirrhotic and 127 non-cirrhotic patients. The incidence density of hospitalisation for NSA was 2.03 episodes/1000 person-years in cirrhotic patients, and 1.27 episodes/1000 person-years in non-cirrhotic patients. After adjustment for age, gender, and other comorbid disorders, Cox's regression analysis showed that cirrhotic patients had a higher occurrence of NSA than non-cirrhotic patients(hazard ratio (HR) = 1.51, 95% confidence interval (CI) = 1.19-1.90; p = 0.001). The patients with complicated cirrhosis were more prone to have NSA than those with non-complicated cirrhosis (HR = 1.46, 95% CI = 1.09-1.96, p = 0.011). CONCLUSIONS This analysis demonstrates that cirrhotic patients have a higher risk of NSA, particularly those with complicated cirrhosis.

Abstract
The pathogenesis of hepatocellular carcinoma (HCC) related to habitual betel quid (BQ) chewing is unclear. Risk of HCCis increased with adverse hepatic fibrosis. This study aimed to assess the impact of chronic viral hepatitis on adverse hepatic fibrosis in HCC related to BQ chewing. This hospital-based case-control study enrolled 200 pairs of age- and gender-matched patients with HCC and unrelated healthy controls. Serologic hepatitis B surface antigen (HBsAg), antibodies to hepatitis C virus (anti-HCV), α-fetoprotein (AFP), and surrogate markers for significant hepatic fibrosis were measured. Information on substance-use habits was obtained with a questionnaire. By analysis of surrogate markers for hepatic fibrosis, the prevalence of significant hepatic fibrosis in patients chewing BQ was between 45.8% and 91.7%, whereas that for patients without BQ chewing was between 18.4% and 57.9%. The difference was significant (P <0.05 for each surrogate marker). Multivariate analysis indicated that cirrhosis with Child-Pugh C (odds ratio (OR) = 3.28; 95% confidence interval (CI), 1.29- 8.37), thrombocytopenia (OR = 3.92, 95% CI, 1.77-8.68), AFP >400 mg/L (OR = 2.21, 95% CI, 1.05-4.66) and male gender (OR = 4.06, 95% CI, 1.29-12.77) were independent factors associated with habitual BQ chewing. In conclusion, adverse hepatic fibrosis and severe liver damage play important roles in the pathogenesis of BQ- related HCC, which could be aggravated by chronic hepatitis B and hepatitis C. BQ-cessation programs and prevention of chronic HBV/HCV infection are needed to prevent HCC related to BQ chewing.

Abstract
To assess the contribution of tumor necrosis factor (TNF)β +252 polymorphisms to risk and prognosis of hepatocellular carcinoma (HCC), we enrolled 150 pairs of sex- and age-matched patients with HCC, patients with cirrhosis alone, and unrelated healthy controls. TNFβ +252 genotypes were determined by polymerase chain reaction with restriction fragment length polymorphism. Multivariate analysis indicated that TNFβ G/G genotype [odds ratio (OR), 3.64; 95%CI, 1.49-8.91], hepatitis B surface antigen (OR, 16.38; 95%CI, 8.30-32.33), and antibodies to hepatitis C virus (HCV) (OR, 39.11; 95%CI, 14.83-103.14) were independent risk factors for HCC. There was an additive interaction between TNFβ G/G genotype and chronic hepatitis B virus (HBV)/HCV infection (synergy index=1.15). Multivariate analysis indicated that factors associated with TNFβ G/G genotype included cirrhosis with Child-Pugh C (OR, 4.06; 95%CI, 1.34-12.29), thrombocytopenia (OR, 6.55; 95%CI, 1.46-29.43), and higher serum α-fetoprotein concentration (OR, 2.53; 95%CI, 1.14-5.62). Patients with TNFβ G/G genotype had poor cumulative survival (p=0.005). Cox proportional hazard model indicated that TNFβ G/G genotype was a biomarker for poor HCC survival (hazard ratio, 1.70; 95%CI, 1.07-2.69). In conclusion, there are independent and additive effects between TNFβ G/G genotype and chronic HBV/HCV infection on risk for HCC. It is a biomarker for poor HCC survival. Carriage of this genotype correlates with disease severity and advanced hepatic fibrosis, which may contribute to a higher risk and poor survival of HCC. Chronic HBV/HCV infected subjects with this genotype should receive more intensive surveillance for early detection of HCC.

Urinary transforming growth factor α and serum α-fetoprotein as tumor markers of hepatocellular carcinoma. Tumour Biol 2013; 35:3689-98. [PMID: 24375326 DOI: 10.1007/s13277-013-1488-2] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/15/2013] [Accepted: 11/27/2013] [Indexed: 12/15/2022] Open
Abstract
This case-control study aimed to evaluate the diagnostic application of urinary transforming growth factor (TGF) α and serum α-fetoprotein (AFP) in hepatocellular carcinoma (HCC). TGFα and AFP were determined in 90 pairs of age- and gender-matched patients with cirrhotic HCC and patients with cirrhosis alone and 60 healthy controls. The results indicated that TGFα and AFP levels in patients with HCC were higher than in those with cirrhosis alone or healthy controls (each P = 0.0001). Multivariate analysis indicated that TGFα (odds ratio (OR) 1.03, 95% confidence interval (CI) 1.05-1.16) and AFP (OR 1.03, 95% CI 1.01-1.06) were closely associated, in a dose-related fashion, with the development of HCC. The optimal cutoff values, determined with the receiver operating characteristic (ROC) curves, were 29 μg/g creatinine for TGFα and 100 ng/ml for AFP, respectively. The areas under ROC curve (AUC) were 0.74 for TGFα and 0.78 for AFP, respectively. Both biomarkers showed the same sensitivity (52.2%), high specificity, high positive predictive value, and moderate positive likelihood ratio. Determination of both markers in parallel significantly increased the AUC (0.91) and diagnostic accuracy (92.2%), with a high sensitivity (86.7 %), specificity (97.8%), positive predictive value (PPV; 97.5%), and moderate positive likelihood ratio (PLR; 39.4). Among 31 cirrhotic HCC with AFP ≤ 20 ng/ml, the calculated AUC for TGFα was 0.79, with a sensitivity of 64.5%, specificity of 96.7%, PPV of 87.0%, and PLR of 19.5. In conclusion, urinary TGFα and serum AFP are complementary tumor markers for detection of HCC with low AFP production.

Abstract
BACKGROUND We noted only rare reports of cirrhotic patients with bacterial endocarditis (BE). There is insufficient data on the risk of BE in liver cirrhosis. This is the first national population-based study evaluating the risk of BE in cirrhotic patients. METHODS We used the National Health Insurance Database, which is derived from the Taiwan National Health Insurance Program. The study cohort comprised 40803 patients with cirrhosis and the comparison cohort consisted of 40841 randomly selected subjects with a similar age and sex distribution. RESULTS Of the total 81644 patients, 192 (0.24%) experienced BE during the 3-year follow-up period, 121 patients from the study cohort (0.30% of the cirrhotic patients) and 71 patients from the comparison group (0.17% of non-cirrhotic patients) (p<0.001). After adjusting for patient age, sex, and comorbid disorders, the Cox regression analysis showed that cirrhotic patients had a high risk of BE compared to non-cirrhotic patients during the 3-year follow-up period (hazard ratio 2.04, 95% confidence interval 1.61-2.44, p<0.001). CONCLUSION We conclude that liver cirrhosis is a risk factor for the occurrence of BE.

Abstract
Background/Aims Cellulitis is a common infectious disease. However, the risk of cellulitis in cirrhotic patients is not well established, and whether liver cirrhosis is a risk factor for cellulitis remains unknown. This study evaluated the relationship between cellulitis and liver cirrhosis. Methods The National Health Insurance Database, which was derived from the Taiwan National Health Insurance program, was used to identify patients. The study group consisted of 39,966 patients with liver cirrhosis, and the comparison group consisted of 39,701 randomly selected age- and sex-matched patients. Results During the 3-year follow-up period, 2,674 (6.7%) patients with liver cirrhosis developed cellulitis, and 1,587 (4.0%) patients without liver cirrhosis developed cellulitis (p<0.001). Following a Cox's regression analysis adjusted for age, sex, and underlying medical disorders, the cirrhotic patients demonstrated a greater risk for the occurrence of cellulitis than the non-cirrhotic patients during the 3-year period (hazard ratio [HR], 1.66; 95% confidence interval [CI], 1.55 to 1.77; p<0.001). Additionally, cirrhotic patients with complications also had a greater risk for the occurrence of cellulitis than those patients without complications (HR, 1.23; 95% CI, 1.14 to 1.33; p<0.001). Conclusions We conclude that cirrhotic patients have a greater risk of cellulitis than non-cirrhotic patients.

Abstract
INTRODUCTION Limited information is available about genotypes of hepatitis C virus (HCV) in intravenous heroin users in Taiwan. The purpose of this study was to examine the concordance of the detection of antibody to HCV and HCV-RNA and to determine the distribution of HCV genotypes in male intravenous heroin users. METHODS This was a cross-sectional study. The study population included 274 intravenous heroin drug users newly sentenced in a male prison in central Taiwan from November 2004 to February 2005, whose antibodies to HCV were positive, and antibodies to human immunodeficiency virus were negative. The mean age was 33.9 years (standard deviation, 7.8). The molecular diagnosis used to identify HCV-RNA was PCR. RESULTS Among 274 subjects, 214 subjects were found to contain HCV-RNA. Positive predictive value of HCV infection using antibody to HCV as an indicator was 78.1%. Among 214 subjects, HCV genotype 2a was the most predominant (58.9%, n = 126), followed by 1a (17.3%, n = 37), 1b (14.5%, n = 31), 2b (8.9%, n = 19) and 1a + 2b (0.4%, n = 1). Age-specific analysis also showed genotype 2a was the most prominent genotype among the 4 age groups, with the highest prevalence in groups aged 20 to 29 years and 30 to 39 years (53.3% and 67.6%, respectively). CONCLUSIONS The concordance of antibody to HCV and HCV-RNA is remarkable in selected high-risk groups. HCV genotype 2a is the most prevalent in male intravenous heroin users in central Taiwan, especially in aged 20 to 29 years and aged 30 to 39 years.

Abstract
We conducted a case-control study to assess the roles of tumor necrosis factor (TNF)-alpha polymorphisms, substance use habits, and chronic hepatitis B virus (HBV)/hepatitis C virus (HCV) infection on the risk for hepatocellular carcinoma (HCC). We enrolled 200 pairs of sex- and age-matched patients with HCC and unrelated healthy controls. TNF-alpha polymorphisms were detected with polymerase chain reaction and direct sequencing. Serum hepatitis B surface antigen (HBsAg) and antibodies to HCV (anti-HCV) were detected. We used a structured questionnaire to obtain information about substance use habits.Multivariate analysis indicated that TNF308.2 allele (odds ratio [OR], 3.23; p = 0.011), habitual betel quid chewing (OR, 3.70; p = 0.011), HBsAg (OR, 23.62; p = 0.0001), and anti-HCV (OR, 38.73; p = 0.0001) were independent risk factors for HCC. Having at least 2 substance use habits was associated with risk for HCC. The more substance use habits, the higher the OR for HCC (p(for trend) = 0.0001). There were additive interactions among TNF308.2 allele, substance use habits, and chronic HBV/HCV infection. Multivariate analysis indicated that TNF308.2 allele (p = 0.001), cigarette smoking (p = 0.0001), and alcohol drinking (p = 0.0001) were independent risk factors for habitual betel quid chewing. Moreover, patients harboring the TNF308.2 allele and/or those with habits of substance use had low serum albumin concentration and platelet count (each p = 0.0001). In conclusion, there are independent and additive interactive effects among the TNF308.2 allele, substance use habits, and chronic HBV/HCV infection on the risk for HCC. Substance use habits or carrying the TNF308.2 allele correlates with disease severity and hepatic fibrosis, which may contribute to higher risks for HCC.

Abstract
We conducted a case-control study to elucidate the role of heat shock protein A1B (HSPA1B) 1267 single nucleotide polymorphism (SNP) on the risk and prognosis of hepatocellular carcinoma (HCC). Subjects enrolled included 150 pairs of sex- and age-matched HCC patients and unrelated controls. Genomic DNA was typed for HSPA1B1267 SNP using polymerase chain reaction with restriction fragment length polymorphism. The frequencies of the HSPA1B P2/P2 genotype and the HSPA1B P2 allele in HCC patients were higher than in unrelated controls (each p = 0.0001). Multivariate analysis identified the following independent risk factors for HCC: HSPA1B P1/P2 genotype (odds ratio [OR], 2.34; 95% confidence interval [CI], 1.07-5.11), HSPA1B P2/P2 genotype (OR, 12.06; 95% CI, 4.43-32.79), hepatitis B surface antigen (HBsAg) (OR, 25.95; 95% CI, 11.88-56.68), and antibodies to hepatitis C virus (anti-HCV) (OR, 70.43; 95% CI, 21.89-226.64). There was an additive interaction between HSPA1B P2 allele carriers and the presence of either HBsAg (synergy index = 2.48) or anti-HCV (synergy index = 1.52). However, as HSPA1B1267 SNP is a silent mutation, it is a surrogate genetic marker for increasing risk of HCC. Our findings indicate that patients with chronic hepatitis B/hepatitis C virus infection who harbor this SNP represent a high-risk group for HCC. They should receive more intensive surveillance for early detection of HCC. Moreover, patients with the HSPA1B P2 allele had significantly longer survival (p = 0.002).The limitations of this study include the unknown functional significance of the HSPA1B1267 polymorphism, the relatively small sample size, the fact that this was not a prospective study of cases and controls, and the questionable generalizability of the findings given the specific ethnic composition of the population studied.

UDP-glucuronosyltransferase 1A7 polymorphisms are associated with liver cirrhosis. Biochem Biophys Res Commun 2007; 366:643-8.

Abstract
Variations in the UDP-glucuronosyltransferase (UGT) 1A7 gene have been found to be related to the development of hepatocellular carcinoma (HCC). Since the pathogenesis of liver cirrhosis is not dissimilar to that of HCC, we hypothesized that UGT1A7 genetic polymorphisms may be associated with liver cirrhosis. PCR-restriction fragment length polymorphism was utilized to determine UGT for 1A7 genotypes for the 159 patients with liver cirrhosis and 263 gender/age matched controls. Simple logistic regression analysis revealed that significant risk factors for liver cirrhosis were (1) hepatitis B virus (HBV) infection, (2) hepatitis C virus (HCV) infection, (3) HBV infection plus HCV infection and (4) low-activity UGT1A7 genotypes. The results of further multivariate logistic regression confirmed these associations. Interaction of low-activity UGT1A7 genotypes and HBV (or HCV) infection produced an additive effect upon the risk for the development of liver cirrhosis [observed odds ratio (OR) (54.59) greater than the expected OR (18.05)]. UGT1A7 low/low genotype was also related to advanced liver cirrhosis (Child-Pugh classes C and/or B) (OR=7.50, P=0.009). This study demonstrates the novel findings that carriage of low-activity UGT1A7 genotypes represents a risk factor for the development and functional severity of liver cirrhosis.

Abstract
BACKGROUND/AIMS Host genetic factor and hepatic fibrosis may predispose to risk for hepatocellular carcinoma (HCC). This study aimed to assess the association between tumor necrosis factor (TNF) alpha polymorphism and hepatic fibrosis, and risk for HCC. METHODS One hundred eight pairs of gender-matched and age-matched patients with HCC and unrelated healthy controls were genotyped for TNF308.2 and TNF238.2 alleles with polymerase chain reaction and direct sequencing. RESULTS The frequency of TNF308.1/TNF308.2 genotype in cases was higher than that in controls [odds ratio (OR) = 4.37]. Multivariate analysis indicated that TNF308.2 allele (OR = 3.23), hepatitis B surface antigen (OR = 17.17), and antibodies to hepatitis C virus (OR = 45.52) were independent risk factors for HCC. Surrogate markers for significant fibrosis implied that cases with the TNF308.2 allele have more advanced liver fibrosis. Moreover, multivariate analysis indicated that cirrhosis with Child-Pugh grade C, low serum albumin, and low platelet count were independent risk factors for carrying the TNF308.2 allele. CONCLUSIONS TNF308.2 allele carriage and chronic hepatitis B virus/hepatitis C virus infection are independent risk factors for HCC. Carriage of the TNF308.2 allele correlates with disease severity and hepatic fibrosis, which may contribute to a higher risk for HCC.

Abstract
PURPOSE The role of betel quid on the development of liver cirrhosis is unclear; we thus designed a community-based case-control study to evaluate the association between betel quid chewing and liver cirrhosis. METHODS A total of 42 cases of liver cirrhosis and 165 matched controls were included for analysis. Questionnaires were administered to obtain histories of betel quid chewing, alcohol consumption, smoking, and family history of liver disease. Hepatitis B surface antigen and anti-hepatitis C antibody were also determined by immunoassay. RESULTS Individuals with more betel quid chewing (more than 55 quid-years vs. less than 55 quid-years and never-chewers, matched odds ratio [OR(m)] = 2.2; 95% confidence interval [CI]: 1.0-5.0) had higher risks for liver cirrhosis. The combined effects on liver cirrhosis by betel quid chewing and the number of other risk factors, including hepatitis B virus (HBV) infection, smoking, and alcohol drinking, were also observed. When individuals with less betel quid chewing (less than 55 quid-years and never-chewers) and with no other risk factors used as a reference, betel quid chewers expressing greater betel quid chewing (more than 55 quid-years) and more risk factors of HBV infection, cigarette smoking, and habitual alcohol drinking expressed a greater risk of liver cirrhosis (OR(m) = 70.8; 95% CI: 4.0-1260.1). CONCLUSIONS Our results suggest that betel quid chewing may play an important role in the development of hepatic cirrhosis. Larger study and cohort studies would be necessary to provide further evidence regarding this finding.

Abstract
BACKGROUND Few studies have focused on the clandestinely consumed amphetamine as a primary drug. The purpose of this study was to estimate the prevalence of hepatitis B virus (HBV) and hepatitis C virus (HCV) infection and the related factors in male amphetamine-inhaling abusers. METHODS This was a cross-sectional study. From November 2004 to February 2005, 285 amphetamine-inhaling male subjects at one prison in Taiwan and 285 age-matched healthy men without history of using illicit drugs or tattooing were enrolled. A face-to-face interview focusing on amphetamine-addicted history and sociodemographic information was used. Hepatitis B surface antigen (HBsAg) and anti-HCV were tested. RESULTS The mean age of the subjects was 34.1 +/- 8.6 years (range 17-75 years). Among 285 subjects, 13.3% were positive for HBsAg, 20.0% positive for anti-HCV and 2.5% positive for combined HBsAg and anti-HCV. Multivariate logistic regression analysis showed that tattoo (odds ratio (OR) 2.97, 95% confidence interval (CI) 1.37-6.43) and elevated alanine aminotransferase (ALT) (OR 3.15, 95% CI 1.49-6.66) were independently related to persons being anti-HCV positive. Elevated ALT was related to persons being HBsAg positive (OR 2.60, 95% CI 1.15-5.89). CONCLUSION Screening of HBV and HCV infection among amphetamine-inhaling abusers remains necessary. Tattoo and elevated ALT are identified as the related factors for being anti-HCV positive. Elevated ALT is the related factor for being HBsAg positive.

Abstract
In the Republic of Palau, a Pacific island nation, approximately 20% of the population is chronically infected with hepatitis B virus (HBV) and is at risk of developing chronic liver disease (CLD), including cirrhosis and hepatocellular carcinoma (HCC). To examine the consequences of HBV infection, we sought to quantify HBV-related CLD mortality in this population. The cause of death was abstracted from death certificates of all persons who died in Palau during 1990-2002. CLD deaths were categorised as cirrhosis or HCC. HBV serological status was determined by review of a hospital database. The cause of death was determined for 1,366 (85%) of 1,608 deaths. CLD was the fifth most common cause of death, accounting for 102 (7%) deaths with a known cause. Of deaths due to CLD, 55 (54%) were from cirrhosis and 47 (46%) were from HCC. Sixty-five percent of CLD decedents and 19% of non-CLD decedents were chronically infected with HBV (P<0.01). The attributable fraction of HBV-related CLD was 54% (58% for cirrhosis and 53% for HCC). CLD mortality rates were approximately twice the worldwide CLD rate. HBV-related CLD is a common cause of death in the Republic of Palau, highlighting the importance of routine infant hepatitis B vaccination, especially in countries with high endemicity.

Abstract
OBJECTIVE To describe the prevalence of hepatitis B virus (HBV) and hepatitis C virus (HCV) infection and the associated risk factors in a prison population. MATERIAL AND METHODS In this cross-sectional study, from November 2004 to February 2005, all 297 newly sentenced prisoners (mean age 37.5+/-11.7 years, age range 16-69 years), who had never used illicit drugs received routine blood check-ups and completed a face-to-face interview. Hepatitis B surface antigen (HBsAg) and anti-HCV antibodies were tested using the t-test, chi-square test, and logistic regression. RESULTS Among the 297 subjects, 13.1% were positive for HBsAg, 8.4% were positive for anti-HCV, and 1.7% were positive for combined HBsAg and anti-HCV. Logistic regression analysis demonstrated that tattooing (odds ratio=2.24, 95% CI=1.03-4.88) and an elevated alanine aminotransferase (ALAT) level (odds ratio=4.10, 95% CI=1.61-10.40) were independently related to HCV infection. CONCLUSIONS Screening of HBV and HCV infection in prison populations remains necessary. Tattooing and elevated ALAT level are identified as the related factors of HCV infection.

Abstract
BACKGROUND The purpose of this study was to explore the epidemiology of hepatitis C virus (HCV) infection and to determine the risk factors for HCV infection among heroin abusers in Taiwan. METHODS This was a cross-sectional study. From November 2004 to February 2005, 577 subjects, including 423 subjects (73.3%) using injectable heroin and 154 subjects (26.7%) using smoked heroin from one male prison located in Taiwan, were enrolled in this study. The mean age was 33.3 +/- 7.9 years (age range 19-65 years). Anti-HCV antibody was tested. A face-to-face interview focusing on sociodemographic information and risk behaviors was addressed. The t test, chi-squared test, and multivariate logistic regression were used. RESULTS The overall prevalence of anti-HCV antibody positivity was 74.9%, with 89.8% among injecting heroin abusers and 33.8% among smoking heroin abusers (P < 0.0001). The multivariate logistic regression analysis demonstrated that needle sharing was independently related to HCV infection (odds ratio = 5.25, 95% confidence interval = 2.48-11.12). CONCLUSIONS The prevalence of anti-HCV antibody positivity among male injecting drug abusers is high in Taiwan. Needle sharing is identified as a potential risk factor for HCV infection.

Abstract
BACKGROUND Limited data are available regarding global hepatitis B virus (HBV)-related morbidity and mortality and potential reduction in disease burden from hepatitis B vaccination. METHODS A model was developed to calculate the age-specific risk of acquiring HBV infection, acute hepatitis B (illness and death), and progression to chronic HBV infection. HBV-related deaths among chronically infected persons were determined from HBV-related cirrhosis and hepatocellular carcinoma (HCC) mortality curves, adjusted for background mortality. The effect of hepatitis B vaccination was calculated from vaccine efficacy and vaccination series coverage, with and without administration of the first dose of vaccine within 24 h of birth (i.e. birth dose) to prevent perinatal HBV infection. RESULTS For the year 2000, the model estimated 620,000 persons died worldwide from HBV-related causes: 580,000 (94%) from chronic infection-related cirrhosis and HCC and 40,000 (6%) from acute hepatitis B. In the surviving birth cohort for the year 2000, the model estimated that without vaccination, 64.8 million would become HBV-infected and 1.4 million would die from HBV-related disease. Infections acquired during the perinatal period, in early childhood (<5 years old), and > or = 5 years of age accounted for 21, 48, and 31% of deaths, respectively. Routine infant hepatitis B vaccination, with 90% coverage and the first dose administered at birth would prevent 84% of global HBV-related deaths. CONCLUSION Globally, most HBV-related deaths result from the chronic sequelae of infection acquired in the perinatal and early childhood periods. Inclusion of hepatitis B vaccine into national infant immunization programs could prevent >80% of HBV-related deaths.

Abstract
OBJECTIVE Alpha-fetoprotein (AFP) is not a useful tumor marker for diagnosis of small hepatocellular carcinoma (HCC). There is over-expression of insulin-like growth factor (IGF)-II in HCC tissue. This study investigates the diagnostic application of IGF-II in small HCC. MATERIAL AND METHODS Serum levels of IGF-II and AFP were determined in 41 patients with small cirrhotic HCC (< or = 3 cm), 41 sex- and age-matched patients with cirrhosis alone (LC), and 41 healthy adults. The optimal cut-off values for diagnosing HCC were determined with receiver operating characteristics (ROC) curve. RESULTS Both IGF-II and AFP levels in HCC were higher than those in LC patients or controls (each p = 0.0001). The IGF-II levels in LC patients were lower than those in controls (p = 0.001). In HCC patients, multivariate analysis indicated that that both IGF-II (odds ratio, 4.54; 95% confidence interval, 2.15-9.55; p = 0.0001) and AFP (odds ratio, 1.05; 95% confidence interval, 1.01-1.08; p = 0.003) were found to be associated with an increased risk of presence of HCC. The optimal cut-off values of IGF-II (4.1 mg/g prealbumin) and AFP (50 ng/ml) were determined with ROC curves. The sensitivity, specificity, and diagnostic accuracy values for IGF-II were 63%, 90%, and 70%, respectively. Those for AFP were 44%, 95%, and 70%, respectively. Determination of both markers in parallel significantly increase the diagnostic accuracy (88%) and sensitivity (80%), with a high specificity (90%). CONCLUSIONS Serum IGF-II level can be used as an independent serologic marker or a complementary tumor marker to AFP for diagnosis of small HCC.

Abstract
This study was designed to determine whether vinyl chloride monomer (VCM) exposure is associated with liver fibrosis. A total of 347 workers with occupational exposure to VCM were systemically examined using liver ultrasonography and routine liver function tests. Vinyl chloride monomer cumulative dose (ppm-month) was estimated by summing the products of air VCM concentration levels and months of employment. Liver fibrosis was defined in subjects with precirrhosis and cirrhosis of liver diagnosed using ultrasonography. Significantly increased risks of developing liver fibrosis were found in workers who had history of high exposure jobs (odds ratio 5.5, 95% confidence interval 1.7-25.4) when compared with workers who did not have history of high exposure jobs. We concluded that there was an increased risk of developing liver fibrosis in PVC workers who had high exposure to VCM.

Abstract
This case-control study aimed to assess the independent and interactive role of habitual betel quid chewing and known risk factors for hepatocellular carcinoma (HCC). Subjects enrolled included 210 pairs of sex- and age-matched cirrhotic patients with HCC, patients with cirrhosis alone, and healthy controls. Information on risk factors was obtained through serologic examination of hepatitis B surface antigen (HBsAg) and antibodies to hepatitis C virus (anti-HCV), and a standardized personal interview with a structured questionnaire. Multivariate analysis indicated that betel quid chewing (odds ratio [OR], 5.81; 95% confidence interval [CI], 2.26-14.94); HBsAg (OR, 37.98; 95% CI, 19.65-73.42); and anti-HCV (OR, 47.23; 95% CI, 18.86-118.25) were independent risk factors for HCC when HCC patients were compared with healthy controls. Using patients with cirrhosis alone as a reference group, multivariate analysis indicated that only betel quid chewing (OR, 1.69; 95% CI, 1.04-2.76) and HBsAg (OR, 1.54; 95% CI, l.01-2.37) were independent risk factors for HCC. There was an additive interaction between betel quid chewing and the presence of either HBsAg (synergy index, 5.22) or anti-HCV (synergy index, 1.35). Moreover, a higher risk of HCC was associated with a longer duration of betel quid chewing and a larger amount of betel quid consumed (each p(for trend) < 0.0001). In conclusion, betel quid chewing is an independent risk factor for cirrhotic HCC. There is an additive interaction between betel quid chewing and chronic hepatitis B and/or hepatitis C virus infection.

Abstract
Betel quid chewing, part of traditional Taiwanese culture, is common in 10%-20% of the human population worldwide. In this case-control study we assessed the independent and interactive role of habitual betel quid chewing and chronic hepatitis B virus (HBV) and hepatitis C virus (HCV) infection on risk of cirrhosis. Subjects enrolled included 210 pairs of sex- and age-matched cirrhotic patients and healthy controls. Information on risk factors was obtained through serologic examination of hepatitis B surface antigen (HBsAg) and antibodies to hepatitis C virus (anti-HCV), and a standardized personal interview with a structured questionnaire. Univariate analysis indicated that betel quid chewing, HBsAg+, anti-HCV+, alcohol drinking, and smoking are significant risk factors for cirrhosis. Multivariate analysis indicated that betel quid chewing (odds ratio [OR], 3.56), HBsAg (OR 20.37), and anti-HCV (OR 31.43) are independent risk factors for cirrhosis. Most betel quid chewers habitually drink alcohol. Although our analysis indicates that betel quid chewing acts independently from alcohol as a risk factor for cirrhosis, the confounding effect of alcohol cannot be excluded entirely by our study. There was an additive effect of the interaction between betel quid chewing and the presence of either HBsAg or anti-HCV. Moreover, a higher risk of cirrhosis was associated with longer duration of betel quid chewing and greater amount of betel quid consumed (each p for trend <0.0001). In conclusion, betel quid chewing appears to be an independent risk factor for cirrhosis. There is an additive interaction between betel quid chewing and chronic HBV/HCV infection.

Abstract
The role of betel quid chewing in the aetiology of hepatocellular carcinoma (HCC) was evaluated in a case-control study including 263 pairs of age- and sex-matched HCC patients and healthy controls. Serum hepatitis B surface antigen (HBsAg), and antibodies to hepatitis C virus (anti-HCV) were determined, and standardized personal interview conducted using a structured questionnaire. Multivariate analysis indicated that betel quid chewing (odds ratio (OR), 3.49; 95% confidence interval (CI), 1.74-6.96), HBsAg (OR, 16.69; 95% CI, 9.92-28.07), anti-HCV (OR, 38.57; 95% CI, 18.15-81.96), and educational duration of less than 10 years (OR, 1.71; 95% CI, 1.05-2.78) are independent risk factors of HCC. In addition, there was an additive interaction between betel quid chewing and chronic infection with either hepatitis B virus (synergy index, 5.37) or hepatitis C virus (synergy index, 1.66). Moreover, risk on HCC increased as duration of betel quid chewing increased, or amount of betel quid consumed (each P for trend < 0.0001).

Abstract
Although alcohol intake and hepatitis B and C virus (HBV and HCV) infections are the major determinants of liver cirrhosis (LC) in western countries, the joint effect of these factors on LC risk has not yet been adequately studied. Data from three case-control studies performed in Italy were used. Cases were 462 cirrhotic patients admitted to Hospitals for liver decompensation. Controls were 651 inpatients admitted for acute diseases unrelated to alcohol. Alcohol consumption was expressed as lifetime daily alcohol intake (LDAI). Three approaches were used to explore the interaction structure. The Breslow and Storer parametric family of relative risk functions showed that an intermediate structure of interaction from additive to multiplicative was the most adequate one. The Rothman synergism index showed that the interaction structure between LDAI and viral status differed significantly from the additive model in particular for high levels of alcohol intake. When multiple regression additive and multiplicative models were compared after adjustment for the known confounding variables. a trend of the interaction structure towards the multiplicative model was observed at increasing levels of consumption. Better methods are needed for assessing mixed interaction structures in conditions characterized by multifactorial etiologies like cirrhosis of the liver.

Abstract
Although alcohol intake and hepatitis C virus (HCV) infection are the major determinants of liver cirrhosis (LC) in Western countries, the joint effect of these two factors on LC risk has not yet been adequately studied. We used data from two hospital-based case-control studies performed in Italy. Cases were 285 cirrhotic patients admitted for the first time to district hospitals for liver decompensation. Controls were 417 patients admitted during the same period, and in the same hospitals as the cases, for acute diseases unrelated to alcohol. Alcohol consumption was expressed as lifetime daily alcohol intake (LDAI). Serum HCV antibodies (anti-HCV) were detected using a second-generation test and recombinant immunoblotting assay. We found a dose-effect relationship between LDAI and the risk of LC in both anti-HCV-negative and -positive subjects. Considering the extreme LDAI categories (LDAI = 0 g, lifetime teetotalers, and LDAI = 175 g), the LC odds ratios increased from 1.0 (reference category) to 15.0 (95% CI, 7.1-31.7) and from 9.2 (95% CI, 2.0-43.2) to 147.2 (95% CI, 42.1-514.3) in anti-HCV-negative and -positive patients respectively. The interaction between LDAI and HCV showed an additive structure for LDAI < 50 g/day and a multiplicative structure for consumption > 125 g/day. Alcohol intake and HCV infection are independent risk factors for symptomatic liver cirrhosis, each being sufficient to induce the disease. In subjects with high alcohol intake, the coexistence of HCV infection multiplies the alcohol-associated risk of cirrhosis. In subjects with low alcohol intake, other factors could be involved.

Abstract
For assessing the role of circulating immune complexes (CIC) in chronic hepatitis B virus (HBV) infection, CICs containing IgM, IgG, and HBsAg were determined by C1q and conglutinin (K) assays in 216 patients with chronic HBV infection and 54 healthy controls. The concentration of each type of CIC in patients is higher than in controls (P = 0.0001). CIC is a common feature of chronic HBV infection with 95.8% of cases having at least one abnormal test result. At least one type of HBsAg-CIC is positive in 54.2% of patients. HBsAg-CIC positivity is associated with HBeAg positivity (P = 0.0001), higher aminotransferase levels (P < 0.002), and younger age (P = 0.001). IgG-CIC or IgM-HBsAg-CIC correlates with higher aminotransferase activity (P = 0.001). In conclusion, HBsAg-CIC correlates with HBV replication. IgG-CIC and/or IgM-HBsAg-CIC correlate with disease activity. Immune-mediated injury may play a role in the pathogenesis of chronic HBV infection.

Abstract
The aim of the study was to assess whether co-infection by hepatitis-B virus (HBV) and hepatitis-C virus (HCV) is associated with a higher risk of developing hepatocellular carcinoma (HCC) than each infection alone. A meta-analysis of data published up to June 1997 was performed. HBsAg and anti-HCV antibodies or HCV RNA (anti-HCV/HCV RNA) were considered as serological markers of current HBV and HCV infection respectively. A total of 32 case-control studies were suitable for a quantitative overview. The summary odds ratios (OR) were 13.7 for HBsAg positivity and 11.5 for anti-HCV/HCV RNA positivity. The OR for anti-HCV was lower among studies using second- or third-generation anti-HCV or HCV RNA (OR, 8.2) with respect to studies with first-generation anti-HCV test (OR, 19.1). When combining data from the studies with second- or third-generation anti-HCV or HCV RNA, the OR for HBsAg positivity and anti-HCV/HCV RNA negativity was 22.5 (95% confidence interval (CI), 19.5-26.0), the OR for anti-HCV/HCV RNA positivity and HBsAg negativity was 17.3 (95% CI, 13.9-21.6), and the OR for both markers positivity was 165 (95% CI: 81.2-374, based on 191 cases and 8 controls exposed). A synergism was found between HBV and HCV infections, the OR for co-infection being greater than the sum and lower than the product of those for each infection alone. The interaction was therefore negative according to the multiplicative model, providing epidemiological evidence both of an independent effect and of interference between the 2 viruses in the carcinogenic process.

Abstract
BACKGROUND/AIMS In order to evaluate the association between alcohol intake and the risk of liver cirrhosis in the absence of B and C hepatitis viruses, we analyzed data from three hospital-based case-control studies performed in various Italian areas. METHODS From the case and control series we excluded HBsAg and/or anti-HCV positive patients. Cases were 221 cirrhotic patients admitted for the first time to hospital for liver decompensation. Controls were 614 patients admitted to the same hospitals during the same period as the cases for acute diseases unrelated to alcohol. Alcohol consumption was expressed as lifetime daily alcohol intake (LDAI). RESULTS We found a dose-effect relationship between LDAI and the risk of liver cirrhosis (LC). Considering the extreme LDAI categories (LDAI = 0 g: lifetime teetotallers and LDAI > or = 100 g), the LC odds ratio (OR) increased from 1.0 (reference category) to 44.7 (95% confidence interval: 95% CI: 20.0-99.9). An increased risk of LC associated with the female gender independent of alcohol consumption was also observed (OR = 2.9; 95% CI: 1.8-4.6). CONCLUSIONS Alcohol intake acts as a risk factor for symptomatic liver cirrhosis also in the absence of HBV and/or HCV infection. Besides alcohol and viruses, some unknown gender-related factors might be involved in the occurrence of the disease.

Abstract
To assess the clinical relevance of transforming growth factor-beta 1 (TGF-beta 1) in the urine of patients with hepatocellular carcinoma (HCC), TGF-beta 1 was measured, by radioimmunoassay, in 140 patients with HCC, 50 cirrhotic patients, 30 patients with chronic active hepatitis, and 50 healthy controls. The results indicate that there were significantly increased urinary TGF-beta 1 levels in patients with HCC. Raised TGF-beta 1 levels were associated, in a dose-related fashion, with increased risk for development of HCC (odds ratio, 1.05, 95% confidence interval, 1.03-1.07). HCC patients with raised TGF-beta 1 levels had shorter survival than those with normal TGF-beta 1 levels (p = 0.038). TGF-beta 1 levels decreased after successful anticancer therapy (p < 0.0001). There was an inverse correlation between TGF-beta 1 and serum alpha-fetoprotein (AFP) (r = -0.199, p < 0.04). Receiver operating characteristics (ROC) curve analysis indicated that parallel determination of TGF-beta 1 and AFP significantly increased the sensitivity and diagnostic accuracy, with a high specificity. In conclusion, raised urinary TGF-beta 1 was associated with HCC development. It is a predictor of poor prognosis, and a tumor marker for diagnosis and therapeutic follow-up of HCC.

Abstract
BACKGROUND Our aim was to assess the relationship between transforming growth factor beta 1 (TGF-beta 1) and alpha-fetoprotein (AFP) levels in hepatocellular carcinoma (HCC). METHODS Urinary TGF-beta 1 and serum AFP were determined in 123 HCC patients, 50 patients with chronic liver disease (CLD), and 50 healthy controls. RESULTS Both TGF-beta 1 and AFP levels were higher in HCC patients than in CLD patients or controls (each, P = 0.0001). There was a negative correlation between TGF-beta 1 and logAFP (r = -0.196, P = 0.029). Multivariate analysis indicated that TGF-beta 1 and AFP were associated with an increased risk of HCC development. By receiver-operating characteristic curve analysis, determination of AFP and TGF-beta 1 in parallel significantly increased the sensitivity and diagnostic accuracy in detecting HCC. CONCLUSION Increased urinary TGF-beta 1 level can be used as a complementary marker to AFP for detection of HCC with low AFP production.

Abstract
To assess the serum alanine aminotransferase (ALT) activity in relation to hepatitis B virus (HBV) and hepatitis C virus (HCV) infections among blood donors, antibodies to HCV (anti-HCV) and hepatitis B surface antigen (HBsAg) were detected in 400 blood donors with normal ALT level (< or = 750 mumol/s per liter), and 76 blood donors with raised ALT level. The prevalence of anti-HCV (10.5%) and HBsAg (28.9%) in the latter was higher than that (2.0% and 17.5%, respectively) in the former (p < 0.001 and p < 0.03, respectively). There was a trend that indicated that the risk of anti-HCV positivity increased with increasing age (p < 0.001). Thirty of 76 (39.5%) donors with raised ALT level were positive for anti-HCV or HBsAg. Compared with HBsAg-positive donors, donors with anti-HCV had higher serum ALT levels (p < 0.01) and greater mean age (p < 0.01). Multivariate analysis indicated that both anti-HCV (odds ratio: 6.2; 95% confidence interval: 2.2-17.8) and HBsAg (odds ratio: 2.2; 95% confidence interval: 1.3-3.9) were significantly associated with raised serum ALT activity. The estimated population-attributable risk was 8.6% for anti-HCV, and 13.8% for HBsAg. In conclusion, although HBV and HCV infections are independent risk factors of raised ALT activity among blood donors, they play a minor role in the etiology of raised ALT activity.

Abstract
To assess whether there is an additive effect between chronic hepatitis B virus (HBV) and hepatitis C virus (HCV) infection on the development of hepatocellular carcinoma (HCC), 400 consecutive cirrhotic patients were followed prospectively with periodic abdominal ultrasound examination and measurement of serum alpha-fetoprotein (AFP) level every 4 months. During a follow-up of 1185 person-years, 80 (20%) patients developed HCC, with an annual incidence of 6.8%. The annual incidence was 2.0% in patients negative for hepatitis B surface antigen (HBsAg) and antibodies to HCV (anti-HCV), 6.6% in patients with HBsAg alone, 7.0% in patients with anti-HCV alone and 13.3% in patients co-infected with HBV and HCV. There was a positive linear trend in the annual incidence of HCC among patients without either marker, patients with single viral infection and patients with dual viral infection (P[for trend] < 0.0001). Cox's proportional hazard model indicated that HCV/HBV co-infection [hazard ratio (HR), 6.41; 95% confidence interval (CI), 1.80-22.80], anti-HCV alone (HR, 3.74; 95% CI, 1.07-13.07) and HBsAg alone (HR, 4.06; 95% CI, 1.23-13.34) were independently risk factors of HCC. In conclusion, there is an additive and independent effect modification of HCV and HBV infection on HCC development.

Abstract
To assess the clinical relevance of transforming growth factor-beta1 (TGF-beta1) in hepatocellular carcinoma (HCC), urinary TGF-beta1 and serum alpha-fetoprotein (AFP) were determined in 94 patients with cirrhotic HCC, 94 age- and sex-matched patients with cirrhosis alone and 50 healthy adults. TGF-beta1 level in HCC was higher than in cirrhosis alone or in healthy controls (each P = 0.0001). There is an inverse correlation between TGF-beta1 and AFP levels (r = -0.292, P = 0.004). Significantly higher TGF-beta1 level was found in HCC patients with worsening Child-Pugh stages, diffuse HCC, tumour size > 3 cm, multilobular tumour and AFP < or = 20 ng ml(-1). TGF-beta1 level decreased after complete treatment with transcatheter arterial chemoembolization (P = 0.0001). The median survival in HCC patients with raised TGF-beta1 was shorter than those with normal TGF-beta1 (P = 0.018). Multivariate analysis indicated that TGF-beta1 and AFP were significantly correlated with the presence of HCC. In addition, TGF-beta1 could be used as a diagnostic marker for HCC, particularly in tumours with low AFP production. In conclusion, elevated urinary TGF-beta1 level is a tumour marker and predictor of poor survival for cirrhotic HCC.

Multivariate analysis indicated that TGF-beta1 and AFP were closely associated, in a dose-related fashion, with the development of HCC. Receiver-operating characteristic (ROC) curves were used to determine the optimal cut-off values of TGF-beta1 (50 microg g(-1) creatinine) and AFP (100 ng ml(-1)). Both TGF-beta1 and AFP showed a high specificity (99%) and positive likelihood ratio. The sensitivity was 53.1% for TGF-beta1 and 55.3% for AFP. The determination of both markers in parallel significantly increased the diagnostic accuracy (90.1%) and sensitivity (84%), with a high specificity (98%) and positive likelihood ratio (40.0). In conclusion, TGF-beta1 and AFP are independent tumour markers of HCC and may be used as complementary tumour markers to discriminate HCC from cirrhosis.

Abstract
To assess the role of hepatitis B e antigen (HBeAg) and its interaction with hepatitis B surface antigen (HBsAg) on the development of hepatocellular carcinoma (HCC), this case-control study included 361 age- and sex-matched pairs of patients with histologically proven HCC and healthy control subjects. HBsAg, HBeAg and antibody to HBeAg (anti-HBe) were detected by radioimmunoassay. Antibodies to hepatitis C virus (anti-HCV) were detected by second-generation enzyme immunoassay. The prevalences of HBeAg (20.2%), HBsAg (80.3%) and anti-HCV (29.5%) in cases were higher than in controls (1.9%, 20.7%, and 2.7% respectively; each P < 0.0001). Using patients negative for HBsAg, HBeAg and anti-HBe as a referent group, univariate analysis indicated that HBsAg alone or HBsAg and HBeAg were risk factors for HCC (P for trend < 0.0001). Calculation of incremental odds ratio indicated that there was additive interaction between HBsAg and HBeAg. Multivariate analysis indicated that HCC development was strongly associated with the presence of HBeAg (odds ratio, 8.1; 95% confidence interval, 2.4-27.1), HBsAg (odds ratio, 68.4; 95% confidence interval, 20.5-227.8) and anti-HCV (odds ratio, 59.3; 95% confidence interval, 13.6-258.4). In conclusion, HBsAg, HBeAg and anti-HCV are independent risk factors for HCC. There is additive and independent effect modification between HBsAg and HBeAg on the development of HCC.

Abstract
BACKGROUND/AIMS This study aimed to assess the effects and interaction between hepatitis B virus and hepatitis C virus infection on the development of chronic hepatitis. METHODS Anti-HCV and HBsAg were detected in 125 histology-proven chronic hepatitis and 250 sex-matched and age-matched healthy controls. RESULTS The prevalences of anti-HCV (24.8%) and HBsAg (68.0%) in patients were higher than in controls (2.4% and 18.0%, respectively; each p < 0.0001). Univariate analysis showed that anti-HCV and HBsAg were strongly associated with the development of chronic hepatitis. Calculation of synergy index and Mantel extension test for trend indicated that there was additive effect modification between HCV and HBV. Multivariate analysis indicated that anti-HCV (odds ratio, 46.1; 95% confidence interval, 9.1-233.2) and HBsAg (odds ratio, 25.8; 95% confidence interval (9.3-67.2) were independent risk factors of chronic hepatitis. The population-attributable risk was estimated as 15.6% for anti-HCV alone, 52.4% for HBsAg alone and 6.8% for both anti-HCV and HBsAg. The frequency of chronic active hepatitis in patients with anti-HCV alone (100%) was higher than in patients with HBsAg alone (75%, p < 0.001). CONCLUSIONS HCV and HBV infections are risk factors of chronic hepatitis. They act independently and probably with additive effect modification.

Abstract
To evaluate the diagnostic application of serum alpha-fetoprotein (AFP) and circulating immune complexes (CICs), AFP, 3% polyethylene glycol (PEG)-CICs, 4% PEG-CICs, and C1q-CICs were determined in 101 patients with cirrhosis alone, 101 sex-matched and age-matched cirrhotic patients with hepatocellular carcinoma (HCC) and 54 healthy controls. Multivariate analysis indicated that AFP (odds ratio 1.014; 95% confidence interval 1.004-1.024) and 3% PEG-CICs (odds ratio 1.011; 95% confidence interval 1.005-1.017) are associated, in a dose-related fashion, with an increased risk for HCC. A receiver operative characteristic (ROC) curve was used to determine the optimal cut-off values of AFP (120 ng ml-1) and 3% PEG-CICs (310 micrograms aggregated IgG equivalent ml-1). The area under ROC curve was 0.875 for AFP and 0.812 for 3% PEG-CIC. Both AFP and 3% PEG-CICs show a high specificity (100%) and positive likelihood ratio. The sensitivity was 65.3% for 3% PEG-CICs and 67.3% for AFP. Determination of both markers in parallel significantly increase the diagnostic accuracy (92.1%) and sensitivity (84%), with a high specificity (100%) and positive likelihood ratio (> 84). In conclusion, both 3% PEG-CICs and AFP are independent risk factors of HCC, and may be used as complementary tumour markers to discriminate HCC from cirrhosis. Determination of 3% PEG-CICs should be performed in cirrhotics negative for AFP to improve detection of HCC.

Abstract
For assessing the role of circulating immune complexes (CIC) in chronic hepatitis C, the relative frequency of CIC was determined in 54 patients with chronic hepatitis C, 15 asymptomatic hepatitis C virus (HCV) carriers, and 54 healthy controls. IgM and IgG containing CIC were studied using both C1q and conglutinin (K) in an immunoglobulin-specific solid-phase enzyme immunoassay. CIC were a common feature of chronic hepatitis C with 96.3% of patients with at least one abnormal test result. The prevalence of elevated IgG-K, IgM-K, IgG-C1q, and IgM-C1q CIC was 70.3%, 50.0%, 64.8%, and 35.1%, respectively. The prevalence of IgG class CIC was higher than IgM class CIC (P = 0.038 for K-CIC and P = 0.01 for C1q-CIC, respectively). There is correlation between IgG-K CIC and IgG-C1q CIC (r = 0.445, P = 0.002), IgG-K CIC and IgM-C1q CIC (r = 0.348, P = 0.020), IgM-K CIC and aspartic aminotransferase (r = 0.321, P = 0.015), IgM-K CIC and alanine aminotransferase (r = 0.301, P = 0.027). Compared to patients with chronic persistent hepatitis and chronic lobular hepatitis, patients with chronic active hepatitis have a higher prevalence of elevated IgG-K CIC (77.2% vs. 40.0%, P = 0.029) and IgM-K CIC (56.8% vs. 20.0%, P = 0.038). The concentration of IgG-K, IgM-K, and IgM-C1q CIC in the former was significantly higher than that in the latter, respectively. In conclusion, IgG class CIC is the major type of CIC in chronic hepatitis C.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
To assess the role of circulating immune complexes (CIC) in chronic hepatitis C virus (HCV) infection, the relative frequency of CIC was determined in 60 patients with chronic hepatitis C alone, 19 patients co-infected with hepatitis B and C, 15 asymptomatic HCV carriers, and 54 healthy controls. Levels of CIC were determined with immunoglobulin-specific C1q-binding and conglutinin (K)-binding immune complex assays. Although there was no statistical difference in the levels of each type of CIC between asymptomatic HCV carriers and healthy controls, elevated levels of CIC containing IgM and IgG were common in patients with chronic HCV infection. Compared to patients with hepatitis C alone, patients co-infected with hepatitis B and C have a higher frequency of abnormal IgM-containing CIC and significantly higher levels of IgM-containing CIC. CIC levels in patients with chronic active hepatitis were significantly higher than those in patients with chronic lobular hepatitis or chronic persistent hepatitis. In conclusion, although CIC containing IgM and IgG were common in patients with chronic hepatitis C, abnormal IgM-containing CIC are the major types of CIC in patients co-infected with hepatitis B and C. An immune-mediated mechanism may play a role in the pathogenesis of chronic hepatitis C.

Abstract
A case control study consisting of 102 patients with HCC, 102 sex-matched and age-matched patients with nonhepatic disease, and 204 matched healthy controls was carried out to investigate the effect of hepatitis B virus (HBV) and hepatitis C virus (HCV) infection on the development of hepatocellular carcinoma (HCC). The prevalence of antibody to HCV (anti-HCV) in HCC (34.3%) was higher than in nonhepatic disease (10.7%, P < 0.001) or in healthy controls (2.4%, P < 0.001). The prevalence of hepatitis B surface antigen (HBsAg) in HCC (77.4%) was higher than in nonhepatic disease (16.6%, P < 0.001) or in healthy controls (19.6%, P < 0.001). Anti-HCV positivity in nonhepatic disease was higher than in healthy controls (P < 0.01). Using patients with nonhepatic disease as controls, stepwise logistic regression analysis indicated that both anti-HCV (odds ratio, 3.4; 95% confidence interval, 2.1-5.6) and HBsAg (odds ratio, 5.6; 95% confidence interval, 3.6-8.5) are independent risk factors for HCC. Using healthy controls, the development of HCC was also strongly associated with anti-HCV (odds ratio, 8.0; 95% confidence interval, 4.3-14.6) and HBsAg (odds ratio, 5.5; 95% confidence interval, 3.7-8.2). Calculation of incremental odds ratio indicated that there is no interaction between HBV and HCV. In conclusion, HBV and HCV are risk factors of HCC. They act independently and without interaction.

Abstract
Antibody to hepatitis C virus (anti-HCV) was found to be an independent risk factor for hepatocellular carcinoma and raised serum alpha-fetoprotein (AFP) level. In addition, the frequency of raised AFP in patients with anti-HCV was higher than in those without (91.5% vs 65.2%, P = 0.0001).

Abstract
BACKGROUND The prevalence of hepatitis C virus (HCV) infection was assessed in patients with non-alcoholic chronic liver disease (CLD). METHODS Antibody levels to HCV (anti-HCV) were assessed in 100 pairs of CLD patients and healthy controls. RESULTS The prevalence of anti-HCV was higher in patients (26.0%) than in controls (2.0%; p = 0.0001). The patient group with anti-HCV was older (p = 0.0001) and had more smokers (p = 0.034), fewer hepatitis B surface antigen carriers (p = 0.0001), and more patients with active liver disease (p = 0.023) and a history of blood transfusion (p = 0.026). Multivariate analysis showed that anti-HCV (odds ratio, 8.1; 95% confidence intervals, 3.7-17.6) was strongly associated with CLD. CONCLUSIONS HCV infection is a risk factor of non-alcoholic CLD, and HCV causes more severe hepatocellular damage than HBV.
