自1981年美国首次从男同性恋患者中报道艾滋病(AIDS)以来,相同症状的患者不断被发现,该疾病也以其惊人的速度在世界范围内传播开来。由于丙型肝炎病毒(HCV)与艾滋病病毒(HIV)有相同的传播途径,使HCV在HIV感染者中得到广泛的传播。据报道,全球HCV感染者中大约6%~10%合并HIV感染,HIV感染者中大约有30%合并HCV感染。因此HIV/HCV重叠感染成为AIDS最关注的领域之一。现对HIV/HCV重叠感染者疾病进展及病毒间在人体内相互作用机制的最新研究进展综述如下。  相似文献

HIV/HCV co-infection from blood products for hemophilia has been a social problem in Japan. Liver transplantation (LT) is an important treatment option for hepatic failure and cirrhosis of the liver in co-infected patients, and appropriate indications for LT, especially organ form deceased donors, are required by society. The aim is to propose priority status for the waiting list for deceased donor (DD) LT in HIV/HCV co-infected patients in Japan based on medical and scientific considerations. Since 2009, we have been working on the subject in research projects under grants-in-aid for health and labour sciences research on AIDS measures provided by the Ministry of Health, Labour and Welfare (the Kanematsu project and Eguchi project). Our research showed that hepatic fibrosis is advanced in HIV/HCV co-infected Japanese patients, especially those with hemophilia who became infected from blood products at a faster rate than HCV mono-infected patients. In addition, those patients who developed portal hypertension had a poor prognosis at a young age. The results of our research contributed to increasing the priority score of those patients on the deceased donor liver transplantation (DDLT) waiting list in 2013 and to establishing a scoring system for DDLT corresponding to the Model for End-stage Liver disease (MELD) score in 2019. This paper introduces changes in priority and the current state of priority of the DDLT waiting list for HIV/HCV co-infected patients in Japan.  相似文献

Opinion statement The life expectancy of HIV seropositive persons is approaching the life expectancy of those who are uninfected with HIV. Hepatitis C virus (HCV) infection has emerged as a worldwide epidemic. Given the similar transmission route between HCV and HIV, there has been an explosion in the number of individuals infected with both viruses. Because of the successful introduction of antiretroviral therapy, patients are more susceptible to new opportunistic infections such as HCV. HCV leads to a more rapid progression to end-stage liver disease in patients with HIV, and the morbidity and mortality related to HCV in co-infected patients is on the rise. Therefore, it has become imperative to treat both HIV and HCV in co-infected patients. The primary goal of HCV therapy is permanent eradication of the virus. Secondary goals include reduction in hepatic fibrosis progression, development of decompensated cirrhosis, and hepatocellular carcinoma. Early studies using standard interferon-alfa for the treatment of HCV in co-infected individuals were discouraging, as poor outcomes, high discontinuation rates, and severe adverse events were observed. The current standard of care for treatment of HCV is pegylated-interferon and ribavirin. New studies have recently demonstrated a higher sustained virologic response rate and a better adverse event profile than previously reported in co-infected patients. As a result, we recommend considering all co-infected patients for HCV therapy while watching closely for unique treatment-related toxicities. The treatment of HCV in co-infected patients should be a high priority for all providers.  相似文献

Aim:  A nationwide survey in Japan revealed that nearly one-fifth of human immunodeficiency virus (HIV)-positive patients are co-infected with hepatitis C virus (HCV). We conducted a study to further analyze the features of liver disease in HIV–HCV co-infected patients.
Methods:  We analyzed 297 patients from eight hospitals belonging to the HIV/AIDS Network of Japan.
Results:  HCV genotypes 1, 2, 3, 4 and mixed genotypes were detected in 55.2, 13.7, 18.9, 0.9 and 11.3% of patients, respectively, in contrast to the fact that only genotypes 1 and 2 are detected in HCV mono-infected patients in Japan. This is compatible with the transmission of HCV through imported blood products contaminated by HCV. Sixteen of 297 HIV–HCV co-infected patients had advanced liver disease accompanied by ascites, hepatic encephalopathy or hepatocellular carcinoma. The average age of such patients was 41.1 ± 14.0 years, which was much younger than that of HCV mono-infected patients with the same complications. The progression speed of liver disease estimated from the changes in the levels of serum albumin, bilirubin, or platelet was slower in patients who achieved sustained virological response with interferon treatment than in those who did not receive it. The overall sustained virological response rate to interferon treatment was 43.3%.
Conclusions:  Our findings suggest that liver disease is more advanced in HIV–HCV co-infected patients than in HCV mono-infected patients, and interferon treatment may retard the progression of liver disease in such patients.  相似文献

With the availability of all-oral, direct acting antivirals (DAAs), hepatitis C virus (HCV) therapy has been revolutionized for HIV/HCV co-infected patients. Indeed HCV cure rates are now no longer different between HCV mono and HIV/HCV co-infected persons and are both greater than 95%. Therefore, current treatment guidelines no longer separate these two groups. Indications for HCV treatment and choice of DAA combination are now the same for all HCV patients. In HIV/HCV co-infection however, drug interactions between HIV and HCV agents need be checked prior to starting HCV therapy. Finally, the higher risk of hepatic decompensation in HIV/HCV co-infected patients, including those receiving successful antiretroviral therapy, continues to make these patients a high priority group for receiving access to modern DAA combination therapy.  相似文献

Hepatitis C virus (HCV)-related liver diseases have contributed to increased morbidity and mortality in HIV-1-infected individuals in the era of effective antiretroviral therapy. HCV transmission patterns have changed among the HIV co-infected population during the last decade, with acute HCV infection emerging worldwide. HIV infection accelerates the progression of HCV-related liver diseases and consequently cirrhosis, liver failure, and hepatocellular carcinoma. However, the current standard treatment of HCV infection with pegylated interferon plus ribavirin results in only a limited viral response. Furthermore, cumbersome pill regimens, antiretroviral related hepatotoxicity, and drug interactions of HCV and HIV regimens complicate therapy strategies. Fortunately, in the near future, new direct-acting anti-HCV agents will widen therapeutic options for HCV/HIV co-infection. Liver transplantation is also gradually accepted as a therapeutic option for end stage liver disease of HCV/HIV co-infected patients.  相似文献

Information on hepatitis C virus (HCV) genotypic distribution among HIV-HCV co-infected patients is lacking in Brazil as well as other Latin American countries. The objective of this study was to evaluate the level of exposure to different risk factors associated with HCV transmission among a group of co-infected patients and to characterize the genotypic distribution of HCV in this cluster. A series of 100 HIV-HCV co-infected patients was analysed. The data to be analysed were collected from specific laboratory tests. Information was collected through a questionnaire. HCV genotyping was carried out by sequencing the 5' non-coding region of HCV. Chi-square and Fischer association tests or Kruskal-Wallis test were used to study the association between HCV transmission-related variables and the established genotypes. In conclusion, exposure to multiple risk factors associated with HCV transmission was common among HIV co-infected patients and an association between HCV genotype 3 and intravenous drug user was observed.  相似文献

AIM To screen for the co-infection of hepatitis B (HBV)and hepatitis C virus (HCV) in human immunodeficiency virus (HIV) infected patients insouthern India.METHODS Five hundred consecutive HIV infected patients were screened for Hepatitis B Virus (HBsAg and HBV-DNA) and Hepatitis C virus (anti-HCV and HCV-RNA)using commercially available ELISA kits; HBsAg, HBeAg/anti-HBe (Biorad laboratories, USA) and anti-HCV (Murex Diagnostics, UK). The HBV-DNA PCR was performed to detect the surface antigen region (pre S-S). HCV-RNA was detected by RT-PCR for the detection of the constant 5' putative non-coding region of HCV.RESULTS HBV co-infection was detected in 45/500 (9%)patients and HCV co-infection in 11/500 (2.2%) subjects.Among the 45 co-infected patients only 40 patients could be studied, where the detection rates of HBe was 55%(22/40), antiHBe was 45% (18/40) and HBV-DNA was 56% (23/40). Among 11 HCV co-infected subjects, 6(54.5%) were anti-HCV and HCV RNA positive, while 3(27.2%) were positive for anti-HCV alone and 2 (18%)were positive for HCV RNA alone.CONCLUSION Since the principal routes for HIV transmission are similar to that followed by the hepatotropic viruses, as a consequence, infections with HBV and HCV are expected in HIV infected patients.Therefore, it would be advisable to screen for these viruses in all the HIV infected individuals and their sexual partners at the earliest.  相似文献

OBJECTIVES: There is limited information on the prevalence of and risk factors for hepatitis C virus (HCV) infection among HIV-1-infected patients in the UK. Our objective was to determine the prevalence of HCV infection among an ethnically diverse cohort of HIV-infected patients in south London, and to extrapolate from these data the number of co-infected patients in the UK. METHODS: A total of 1017 HIV-1-infected patients who had attended King's College Hospital HIV clinic between September 2000 and August 2002 were screened for HCV antibody using a commercial enzyme-linked immunosorbent assay (ELISA). Positive results were confirmed by polymerase chain reaction (PCR) or recombinant immunoblot assay. Demographic, clinical and laboratory data were obtained from the local computerized database and medical records. We applied our HCV prevalence rates in the different HIV transmission groups to the estimated number of HIV-infected persons in these groups in the UK, to obtain a national estimate of the level of HIV-HCV co-infection. RESULTS: Of the 1017 HIV-1-infected patients, 407 (40%) were white men, 158 (15.5%) were black African men, 268 (26.3%) were black African women, and 61 (6%) and 26 (2.6%) were black Caribbean men and women, respectively. Heterosexual exposure was the most common route of HIV acquisition (53.5%), followed by men having sex with men (36.9%), and current or previous injecting drug use (IDU) (7.2%). The overall prevalence of HCV co-infection was 90/1017 (8.9%), but this varied substantially according to route of transmission, from 82.2% among those with a history of IDU (which accounted for 67% of all HCV infections), to 31.8% in those who had received blood products, to 3.5% and 1.8% in those with homosexually and heterosexually acquired infection, respectively. Multivariate logistic regression analysis identified several independent risk factors for HCV infection: a history of IDU [odds ratio (OR) = 107.2; 95% confidence interval (CI) = 38.5-298.4], having received blood products (OR = 16.5; 95% CI = 5.1-53.7), and either being from a white ethnic group (OR = 4.3; 95% CI = 1.5-12.0) or being born in Southern Europe (OR = 6.7; 95% CI = 1.5-30.7). Based on the 35,473 known HIV-1-infected persons in the UK and the 10 997 estimated to be unaware of their status, we projected that there are at least 4136 HIV-HCV co-infected individuals in the UK and 979 who are unaware of their status. CONCLUSIONS: Overall, 9% of our cohort was HIV-HCV co-infected. The prevalence was highest among intravenous drug users (82%), who accounted for most of our HCV cases, and lowest among heterosexual men and women from sub-Saharan Africa and the Caribbean [< 2%]. Our estimate that a significant number of co-infected persons may be unaware of their HIV and HCV status, highlights an urgent need to increase the uptake of HCV and HIV testing, particularly among injecting drug users, to reduce the risk of onward transmission.  相似文献

Co-infection with HIV and hepatitis C (HCV) is common due to similar risk factors. Twenty-five to thirty percent of HIV+ patients are co-infected with HCV. HCV infection in HIV+ patients is associated with higher rates of fibrosis, progression to cirrhosis and decompensated liver disease, and liver-related mortality. The ultimate HCV treatment goal is viral eradication, or sustained virologic response (SVR) which results in decreased liver-related morbidity and mortality. Prior therapies were suboptimal in co-infected patients. However, the new HCV direct-acting antiviral agents provide excellent treatment options in co-infected patients with response rates and adverse events similar to the HCV mono-infected population. Drug interactions between HIV treatments and HCV treatments can be challenging and must be taken into consideration. To optimize outcomes, co-infected patients should be managed by experienced providers or in the setting of a collaborative multidisciplinary approach. This article will review the current treatment rationale and recommendations for HIV-HCV-co-infected patients.  相似文献
