Many recent and significant advances in the field of chronic viral hepatitis, including therapy, suggest that an update on chronic hepatitis is timely. Chronic hepatitis B virus infection remains a significant worldwide cause of liver cirrhosis and hepatocellular carcinoma, despite the wide availability of a long established and effective vaccine. Transmission occurs via perinatal, sexual, and parenteral routes (particularly intravenous drug abuse and although blood products still carry a risk, this is now extremely low in Western countries). Only a minority of infected adult cases develop chronic hepatitis but in children under 1 year, 90% develop chronic hepatitis. The clinical spectrum of chronic liver injury ranges from mild inflammation to end stage liver cirrhosis. Interferon alfa has been the mainstay of treatment for patients with active disease but nucleoside analogues (lamivudine and adefovir) are now available with similar efficacy. Patients with end stage liver disease and hepatocellular carcinoma can be offered transplantation but infection in the graft is commonplace. The combination of hepatitis B immunoglobulin and newer antiviral drugs reduce the incidence and severity of graft infection significantly. The hepatitis C virus epidemic of the latter half of the 20th century now affects more than 1% of populations worldwide. This RNA virus is spread parenterally and is becoming the leading indication for liver transplantation. The majority of patients develop chronic hepatitis, which may be progressive, evolving to significant liver disease (cirrhosis or hepatocellular carcinoma) in about 20% cases after decades. Treatment with the combination of interferon alfa and ribavirin is successful in up to 40% cases. Liver transplantation is a therapeutic option for some but graft infection is universal and often complicated by progressive liver fibrosis. A vaccine remains a remote prospect so that prevention is crucial. Hepatitis D virus infection occurs on a background of hepatitis B virus infection and can also cause liver damage. The response to antiviral therapy is poor. The newer "hepatitis" viruses G and TT do not cause significant liver injury. 相似文献

Hepatitis C virus in intravenous drug users 总被引:3,自引:0,他引:3

Sera from 172 intravenous drug users were tested for the presence of antibodies to hepatitis C virus (anti-HCV). The results were analysed in relation to aspects of the history of drug use and evidence of liver disease. The presence of anti-HCV was strongly associated with duration of intravenous drug use. Two-thirds of patients were anti-HCV seropositive within two years of commencing regular intravenous drug use, and there was 100% seropositivity among people injecting drugs for more than eight years. Seropositivity for hepatitis C virus closely paralleled exposure to hepatitis B virus, which was also endemic in this population. In contrast, only one patient tested positive for antibodies to the human immunodeficiency virus. The presence of anti-HCV correlated poorly with biochemical markers of hepatitis. About half the patients with anti-HCV had normal serum levels of alanine aminotransferase, whereas an abnormal liver biochemistry was frequently observed in anti-HCV seronegative subjects. Previous studies of non-A, non-B hepatitis that have used abnormal liver biochemistry as a marker have underestimated the prevalence of chronic hepatitis among intravenous drug users; the use of a specific screening test reveals that infection with hepatitis C virus is very common in this population. 相似文献

目的了解我市吸毒人群中艾滋病、梅毒和丙肝的感染率变化趋势以及吸毒行为的变化情况,以获得我市艾滋病流行趋势及危险因素,及时总结我市艾滋病哨点监测工作经验及监测工作中存在的问题,更好地有针对性地开展艾滋病宣传教育及防治工作。方法按照中国疾病预防控制中心性艾中心艾滋病哨点/丙肝哨点监测实施方案要求进行监测。结果 2010~2011年我市监测的吸毒人员均为男性,青壮年、已婚者居多,多数吸毒者为初中以下文化,吸毒人群的吸毒方式以口吸为主,大都吸食海洛因。2010年监测的421例吸毒人员中有商业性行为占14.01%,静脉注射吸毒者占16.15%,共用针具者占19.12%,HIV抗体阳性1例,阳性检出率为0.24%,梅毒抗体检测阳性8例,检出率为1.90%,丙肝抗体阳性46例,检出率为10.93%。2011年监测的411例吸毒人员中有商业性行为者占21.41%,静脉注射吸毒者占22.87%,共用针具者占37.23%,未检出HIV抗体阳性者,梅毒抗体检测阳性23例,检出率为5.59%,丙肝阳性56例,检出率为13.63%。结论我市被调查的吸毒人群中艾滋病感染率较低,梅毒、丙肝感染率较高,呈上升趋势;静脉注射吸毒、共用针具、商业性行为等危险行为发生率有所升高。在吸毒人群中加强艾滋病防治知识,进行健康教育和行为干预刻不容缓。 相似文献

The prevalence of delta infection was studied in 3986 individuals seropositive for hepatitis B surface antigen (HBsAg), who were seen in Melbourne between 1971 and 1985. The group comprised 2004 patients with acute hepatitis B, 1820 asymptomatic HBsAg carriers, 139 HBsAg carriers with evidence of chronic liver disease, and 23 carriers who had suffered more than two separate attacks of acute hepatitis. Markers of delta infection were found almost exclusively among intravenous drug abusers and their close contacts. Studies of stored sera suggest that delta infection was introduced into this group about 1970. In carriers with no evidence of chronic liver disease, the prevalence of delta infection was highest among intravenous drug abusers (19.2%). In carriers with evidence of chronic liver disease, delta markers were present in 20.1% and all 23 carriers with recurrent acute hepatitis had evidence of infection with the delta virus. 相似文献

Hepatitis B in general practice: epidemiology, clinical and serological features, and control 总被引:1,自引:0,他引:1
In an outbreak of hepatitis B virus infection in a south Wales village 31 cases were identified over 16 months. Spread of the infection was by sharing needles and by sexual contact. Twenty seven patients were known to have symptoms, of whom nine had an anicteric illness. Generally the illness was mild with no deaths, and there was only one chronic carrier. Two patients were only transiently positive for hepatitis B surface antigen. The outbreak was controlled by vigorous contact tracing and counselling. Despite an enormous increase in workload for the general practitioner and problems including disposal of contaminated needles, outbreaks of hepatitis B virus infection may adequately be treated in the community. 相似文献

Intravenous drug users who presented to the Albion Street (AIDS) Centre for human immunodeficiency virus (HIV) antibody screening during the period March 1, 1985 to January 31, 1989, were included in this study. Information on medical history and HIV risk-related behaviour was collected by means of a standardized, computer-coded medical record. Of the 1222 intravenous drug users in this study, 72.3% were men, 26.9% were women and 0.8% were transsexual, with 60.1% of the total claiming exclusive heterosexuality. Of the sample, 40.2% were current intravenous drug users, and 86.8% recorded having shared needles and syringes. Among this sample, the over-all prevalence of HIV seropositivity was 14.5%. Of subjects who were diagnosed as HIV seropositive, 43.8% were homosexual men, 13.1% were bisexual men and 5.3% were heterosexual men. Of all intravenous drug users, 49.9% had a history of at least one sexually-transmitted disease, with 21.8% reporting a history of more than one. Fifty-two per cent of the sample reported that they had been infected with hepatitis B previously. There was no over-all increase in the annual rate of HIV infection among this population of intravenous drug users. The sexual activity and prevalence of hepatitis and other sexually-transmitted diseases among this group are suggestive of widespread, continuing risk behaviour. 相似文献
