目的:C型肝炎目前并未有疫苗预防接种,因此对C型肝炎的流行情况、尤其是C型肝炎病毒的致病机转及感染途径方面的探讨,以其切断感染源,是为迫切需要.方法:以多步骤抽样法在区、街道中心与郊乡地区筛检54所幼儿园.从静脉采血取得血清,以自动化仪器测试肝功能指针研究数据,以SPSS软件系统做统计分析.结果:有19位儿童为C型肝炎抗体阳性,占2.3%.男孩的C型肝炎抗体流行率比女孩高,但经统计学处理无显著差异(0Rm:1.6;95% CI:0.9~2.8;P=0.08).3~4岁年龄段的流行率比5~6岁低(ORm:2.2;95% CI:1.1~4.2;P=0.02).经多变项调整分析后,具C型肝炎抗体流行率的儿童且受B型肝炎病毒自然感染的比未被感染的高,但经统计学处理无显著差异(ORm:2.6;95% CI:0.9~7.4;P=0.08 for HBV-infected vs. uninfected).结论:在龙岗区,C型肝炎病毒的感染与B型肝炎病毒自然的感染,除了性别与居住地外,应该还有更多的共同传染途径存在.另外,为数不少的居民相信药物注射比口服治疗快,尤其是对儿童的治疗,因此间接造成C型肝炎病毒感染的数量增加. 相似文献

Taiwan is a hyperendemic area of hepatitis B virus (HBV) infection where chronic hepatitis B is the most important cause of liver cirrhosis and hepatoma. Since, diagnostic kit for detecting hepatitis C virus (HCV) infection has been developed, HCV was found to be another important etiology of chronic liver disease. In order to study the seroprevalence of HCV infection among preschool children after mass hepatitis B vaccination program in Taiwan, a community-based survey was carried out in 54 kindergartens in 10 urban areas, 10 rural areas, and two aboriginal areas randomly selected through stratified sampling. Serum specimens of 2538 preschool children were screened for the HCV antibodies (anti-HCV) by a commercially available third-generation microparticle enzyme immunoassay and for HBV markers by radioimmunoassay methods. The multivariate-adjusted odd ratios (ORm) with their 95% confidence intervals (CI) were estimated through the multiple logistic regression analysis. A total of 58 children were anti-HCV seropositive, giving a prevalence of 2.3%. The prevalence of anti-HCV was 1.0% (5 of 484) among aboriginal children, a significantly decreased seroprevalence compared with those among other ethnic groups after multivariate adjustment. Boys had a higher anti-HCV seroprevalence, but not statistically significantly different from girls (ORm: 1.6; 95% CI: 0.9–2.8; p = 0.08). The seroprevalence of the age group of 3–4 years was lower than that of the age group of 5–6 years (ORm: 2.2; 95% CI: 1.1–4.2; p = 0.02). After multivariate adjustment, preschool children with natural HBV infection had a higher anti-HCV seroprevalence, but not statistically significantly different from those without natural HBV-infection (ORm: 2.6; 95% CI: 0.9–7.4; p = 0.08 for HBV-infected vs. uninfected). HCV infection varies with gender, residential area, and natural HBV infection. HCV and HBV might share common transmission routes in Taiwan. 相似文献

A serological survey of hepatitis B virus (HBV) and hepatitis C virus (HCV) infections was carried out on a random sex- and age-stratified sample of 1006 individuals aged 25-64 years in the Seychelles islands. Anti-HBc and anti-HCV antibodies were detected using commercially available enzyme-linked immunosorbent assays (ELISA), followed by a Western blot assay in the case of a positive result for anti-HCV. The age-adjusted seroprevalence of anti-HBc antibodies was 8.0% (95% CI: 6.5-9.9%) and the percentage prevalence among males/females increased from 7.0/3.1 to 19.1/13.4 in the age groups 25-34 to 55-64 years, respectively. Two men and three women were positive for anti-HCV antibodies, with an age-adjusted seroprevalence of 0.34% (95% CI: 0.1-0.8%). Two out of these five subjects who were positive for anti-HCV also had anti-HBc antibodies. The seroprevalence of anti-HBc was significantly higher in unskilled workers, persons with low education, and heavy drinkers. The age-specific seroprevalence of anti-HBc in this population-based survey, which was conducted in 1994, was approximately three times lower than in a previous patient-based survey carried out in 1979. Although there are methodological differences between the two surveys, it is likely that the substantial decrease in anti-HBc prevalence during the last 15 years may be due to significant socioeconomic development and the systematic screening of blood donors since 1981. Because hepatitis C virus infections are serious and the cost of treatment is high, the fact that the prevalence of anti-HCV antibodies is at present low should not be an argument for not screening blood donors for anti-HCV and eliminating those who are positive. 相似文献

OBJECTIVE: Infection with hepatitis B (HBV) and hepatitis C (HCV) viruses is relatively common throughout South-East Asia and chronic infection can lead to severe consequences. This study assesses knowledge about HBV and HCV and estimates the seroprevalence of markers for these viruses in immigrants from Laos and Cambodia. METHODS: Ninety-five Laotian (aged 18-82 years) and 234 Cambodian (15-92 years) immigrants participated in separate community-based surveys conducted during 1998 and 2002, respectively. Participants completed a questionnaire on health status and level of knowledge about viral hepatitis. Blood samples were collected and tested for the presence of HBV and HCV markers. RESULTS: Nine per cent of Laotian and 8% of Cambodian participants were infected with HBV. While 49% of Laotian and 64% of Cambodian participants showed evidence of previous exposure to HBV, 30% and 9%, respectively, were vulnerable to infection. The seroprevalence of antibodies to HCV was 3% in the Laotian and 8% in the Cambodian participants. Between one-fifth and one-third of the Laotians and Cambodians who had heard of HBV and HCV knew of possible transmission routes for the viruses. Most of those with HBV or HCV infection were unaware they were infected. CONCLUSIONS: These findings indicate a significant prevalence of undetected HBV and HCV infections and an urgent need for the provision of culturally relevant information about viral hepatitis in immigrants of South-East Asian origin. 相似文献

The study was conducted among 76 injecting drug users (IDU) from seven Croatian cities during a three-year period (2005-2007). Each participant completed a questionnaire on sociodemographic characteristics and potential risk factors for hepatitis C virurs (HCV) infection followed by anti-HCV and anti-HIV antibody testing. The mean patient age was 30. The majority of patients (69.8%) reported more than one potential exposure to HCV: 97.1% had shared injecting equipment, 75% reported risk sexual behaviour, and 56.3% reported a history of travelling abroad. The overall HCV seroprevalence was 51.3% (95% CI = 40-63%). HCV seroprevalence increased with increasing number of risk behaviours (p = 0.026). Needle sharing frequency was the most important risk factor for hepatitis C. The HCV seroprevalence rate ranged from 27.3% in IDUs who answered that they shared needles occasionally to 100% in IDUs who always shared needles (p < 0.001). No other risk factors (age, gender, educational level, marital and employment status, history of travelling abroad and sexual risk behaviour) were associated with HCV seropositivity. 相似文献

This study evaluated the roles of multiple factors in hepatitis C virus (HCV) infection, with emphasis on the modification of various individual characteristics on the risk associated with percutaneous exposure to blood. Serum samples taken from 4869 men in Taiwan within a cohort study were tested for HCV antibody. The overall positive rate of anti-HCV was 1.6%. In a logistic regression, factors positively associated with anti-HCV positivity were previous blood transfusion (odds ratio [OR] = 7.28: 95% confidence interval [CI] = 4.26-12.45), a history of surgery (OR = 2.06: 95% CI = 1 23-3.46), and lower educational levels (OR = 1.94; 95% CI = 1.14-3.32). The anti-HCV positive rate was significantly lower in hepatitis B surface antigen (HBsAg) carriers than in non-carriers (OR = 0.60; 95% CI = 0.37-0.95). Ageing, lower educational levels, O blood group, and Taiwanese ethnicity enhanced the likelihood of HCV infection through blood transfusion/surgery, whereasHBsAg status, cigarette smoking, and habitual alcohol drinking reduced it. 相似文献

The present study examined the effect of hepatitis B virus (HBV) and alcohol intake, and the role of hepatitis delta virus (HDV) and hepatitis C virus (HCV) in the aetiology of chronic liver disease in Albania. A total of 106 cases of liver cirrhosis or chronic hepatitis were compared to 195 control patients without these or other liver diseases. Adjusted odds ratios were 52.7 (95% CI 22.7-122) for HBV surface antigen, 26.9 (95% CI 4.9-147) for anti-HCV, 26.2 (95% CI 3-1-221) for anti-HDV, 2.4 (95% CI 1.3-4.4) for lifetime alcohol intake and 2.3 (95% CI 1-5.5) for duration of alcohol intake. Although not significant, an interaction was suggested between HBsAg and anti-HCV and between HBsAg and alcohol intake. Our study underlines the role of hepatitis viruses in the development of chronic liver diseases. Additionally, it suggests that heavy alcohol intake may magnify the effect of HBV on these diseases. HBV vaccination and alcohol abstention appear to be important strategies to reduce the risk of liver cirrhosis and chronic hepatitis in Albania. 相似文献

BACKGROUND: Limited information about the epidemiology of hepatitis C virus (HCV) infection is available in Puerto Rico, one of the areas hardest hit by the human immunodeficiency virus/acquired immune deficiency syndrome (HIV/AIDS) epidemic. We estimated the prevalence of HCV infection and identified correlates of seropositivity in the municipality of San Juan, Puerto Rico. METHODS: A probability cluster design was employed to select a sample of households representative of the population aged 21-64 years in San Juan during 2001-2002. All 964 subjects completed a face-to-face interview to gather data on demographics and self-reported risk behaviours followed by venipuncture for HCV antibody testing. Variables that were at least marginally associated with HCV seroprevalence (P < 0.10) in the bivariate analyses were considered for inclusion into the multiple logistic regression model to estimate the adjusted prevalence odds ratio (POR). RESULTS: Overall weighted prevalence of HCV infection was 6.3% (95% CI 3.6-10.9%). A significant (P < 0.05) higher prevalence was observed among subjects with the following characteristics: age 30-49 (9.5%), male sex (10.6%), < or =12 years of education (9.6%), no health coverage (12.6%), lifetime heroin use (39.2%), lifetime cocaine use (39.6%), tattooing practices (34.2%), history of imprisonment (32.8%), and self-reported histories of hepatitis B virus infection (30.4%) and HIV/AIDS (92.1%). Multivariate logistic regression revealed that tattooing practices (POR = 8.9; 95% CI 1.7-44.7), lifetime cocaine use (POR = 5.5; 95% CI 2.2-13.5), blood transfusions prior to 1992 (POR = 4.0; 95% CI 1.6-10.1), lifetime heroin use (POR = 3.3; 95% CI 1.4-7.8), and history of imprisonment (POR = 2.3; 95% CI 1.1-4.9) remained significantly associated with HCV seropositivity. CONCLUSIONS: The large prevalence of HCV infection observed in Puerto Rican adults residing in San Juan suggest that HCV infection is an emerging public health concern and merits further investigation. 相似文献
