Antiretroviral treatment change among HIV, hepatitis B virus and hepatitis C virus co-infected patients in the Australian HIV Observational Database

OBJECTIVES: To assess the impact of highly active antiretroviral therapy (HAART) on rates of change of antiretroviral treatment among patients co-infected with hepatitis B virus (HBV) and/or hepatitis C virus (HCV) in the Australian HIV Observational Database (AHOD). METHODS: Analysis was based on 805 of the 2218 patients recruited to the AHOD by March 2003, who had commenced HAART after 1 January 1997, who had recorded test results for HBV surface antigen and anti-HCV antibody, and who had follow-up of more than 3 months. The effect of hepatitis co-infection on the rate of antiretroviral treatment change after commencing HAART was assessed using a random-effect Poisson regression model. RESULTS: Among those included in the analyses, the prevalences of HBV and HCV were 4.8% and 12.8%, respectively. The overall rate of combination antiretroviral treatment change was 0.74 combinations per year. Factors independently associated with an increased rate of change of combination antiretroviral treatment were: prior AIDS-defining illness; prior exposure to double combination antiretroviral therapy; and antiretroviral treatment class. Co-infection with HBV and/or HCV was not found to be significantly associated with the rate of combination antiretroviral treatment change. CONCLUSIONS: While both HBV and HCV co-infections are relatively common in the AHOD, they do not appear to be serious impediments to the treatment of HIV-infected patients.

A case of HIV co-infected with hepatitis B virus precore/core deletion mutant treated by entecavir.

We report a case of a HIV and hepatitis B virus (HBV)-co-infected patient to whom entecavir (ETV) was administered initially before the notification regarding the potential mutagenesis effect on HIV against the nucleoside analog. Since initial evaluations indicated the advanced stage of chronic hepatitis B and preserved numbers of peripheral CD4+ lymphocytes without the manifestation of immunodeficiency, priority was given to the management of HBV. We started HBV therapy with ETV at a dose of 0.5 mg daily without using any HIV drugs. The viral loads of both HBV and HIV-1 decreased gradually during the 5 months following the initial administration of ETV. HBV was well controlled by the gradual replacement of ETV with highly-active antiretroviral therapy against HIV with a regimen including atazanavir, emtricitabine, and tenofovir. HBV was genotyped as A2 with the quasispecies pool consisting of the -1G precore/core deletion mutant strain.     

Prevalence of hepatitis B virus infection in Japanese patients with HIV.

Patients with HIV infection are frequently infected with hepatitis viruses, which are presently the major cause of mortality in HIV-infected patients after the widespread use of highly active antiretrovirus therapy. We previously reported that approximately 20% of HIV-positive Japanese patients were also infected with hepatitis C virus (HCV). Hepatitis B virus (HBV) infection may also be an impediment to a good course of treatment for HIV-infected patients, because of recurrent liver injuries and a common effectiveness of some anti-HIV drugs on HBV replication. However, the status of co-infection with HIV and HBV in Japan is unclear. We conducted a nationwide survey to determine the prevalence of HIV-HBV co-infection by distributing a questionnaire to the hospitals belonging to the HIV/AIDS Network of Japan. Among the 5998patients reported to be HIV positive, 377 (6.4%) were positive for the hepatitis B surface antigen. Homosexual men accounted for two-thirds (70.8%) of the HIV-HBV co-infected patients, distinct from HIV-HCV co-infection in Japan in which most of the HIV-HCV co-infected patients were recipients of blood products. One-third of HIV-HBV co-infected patients had elevated serum alanine aminotransferase levels at least once during the 1-year observation period. In conclusion, some HIV-infected Japanese patients also have HBV infection and liver disease. A detailed analysis of the progression and activity of liver disease in co-infected patients is needed.     

HCV对HIV/HCV共感染患者病情进展的影响

目的探讨HCV对HIV/HCV共感染病情进展的影响。方法研究对象为2012年8月到北京佑安医院随访的HIV/HCV共感染者29例及HIV单独感染者20例。两组患者年龄、性别及HIV感染时间及感染方式、感染的HIV病毒亚型均具有可比性。外周血生化指标检测并采用瞬时弹性扫描仪FibroScan评估肝脏功能及纤维化程度,运用流式细胞技术检测外周血CD4+T、CD8+T细胞绝对计数。两组计量资料比较采用t检验,计数资料比较采用χ2检验。结果 HIV/HCV共感染组ALT、AST及TBil水平分别为(76.16±81.25)U/L、(87.66±71.32)U/L、(14.21±9.56)μmol/L,明显高于HIV单独感染组[(27.74±20.63)U/L、(45.65±16.95)U/L、(10.26±3.22)μmol/L],差异具有统计学意义(P值分别为0.004、0.005及0.046)。与HIV单独感染组相比,HIV/HCV共感染组Stiffness指数有升高的趋势,但差异无统计学意义(t=1.889,P=0.080)。HIV/HCV共感染组HIV病毒载量(拷贝/ml)的对数值为3.66±0.97明显高于HIV单独感染组的3.02±0.90(t=2.251,P=0.030)。HIV/HCV共感染组、HIV单独感染组CD4+T淋巴细胞计数及CD4+T/CD8+T细胞比例分别为(374.25±185.48)/μl及(0.33±0.17)、(496.45±230.98)/μl及(0.46±0.27),HIV/HCV共感染组CD4+T淋巴细胞计数及CD4+T/CD8+T细胞比例低于HIV单独感染组,差异具有统计学意义,P值分别为0.048、0.043。共感染组艾滋病发病率(27.59%)呈现出较HIV单独感染组(5%)高的趋势(P=0.063)。结论HCV促进HIV/HCV共感染者肝脏损伤,增强HIV复制,加剧机体免疫功能损伤,HCV可能加速HIV/HCV共感染者的病情进展。     

HIV/HCV合并感染的相互影响及抗病毒治疗研究进展

HIV和HCV具有相似的传播途径,主要为输血/血制品、性接触、母婴垂直及静脉注射吸毒等,因此HIV/HCV合并感染率高。HIV和HCV在体内有复杂的相互作用,使合并感染者的病程变化多样,治疗难度加大。现将HIV/HCV合并感染后病毒间相互作用机制及临床抗病毒治疗的研究进展综述如下。     

人类免疫缺陷病毒/丙型肝炎病毒混合感染者抗丙型肝炎病毒治疗的进展

由于人类免疫缺陷病毒（HIV）和丙型肝炎病毒（HCV）有相同的传播途径,HIV/HCV混合感染现象十分普遍,已成为严重的公共卫生问题。高效抗逆转录病毒治疗（HAART）的应用显著减少了与HIV感染相关的发病率和病死率,而HCV混合感染引起的慢性肝脏疾病日益成为HIV/HCV混合感染者发病和死亡的重要因素。HIV/HCV混合感染者HCV相关肝病的风险增加,有效的抗HCV治疗对延长这一人群的生存期至关重要。本文就抗HCV治疗对象的评估、治疗时机的选择、治疗的方法、治疗监测和疗效评估以及治疗注意的问题作一综述。     

The rate of treatment of chronic hepatitis C in patients co-infected with HIV in an urban medical centre

Hepatitis C virus (HCV) and human immunodeficiency virus (HIV) co-infection is common. HIV co-infection results in a higher rate of histologic progression and shorter interval to HCV-related cirrhosis. Successful treatment of HCV with interferon-based therapy reduces the morbidity and mortality of patients. Significant factors may limit the availability of treatment in co-infected patients. The rate of treatment of HCV and limiting factors to treatment in a co-infected population in an urban setting were determined. A retrospective review of co-infected patients was conducted at our liver and gastrointestinal (GI) clinics for treatment of HCV from July 2001 to June 2002. Treatment of HCV and reasons for nontreatment were recorded. A total of 104 HCV/HIV co-infected patients were identified. Seventy-two per cent were males. Mean age was 47.2 years (32-72). Seventy-four of the 82 (90%) with identifiable risk factors for HCV infection had a history of intravenous drug use (IVDU). Twenty per cent (21/104) of the total underwent a liver biopsy. Sixty-seven per cent who had a liver biopsy were treated. Overall, sixteen patients were treated. Eighty-eight (85%) patients were not treated for the following reasons: 13 refused treatment, and 75 were ineligible. Of the ineligible patients, 40% were noncompliant with visits, 15% were active substance abusers, 13% had decompensated cirrhosis, 8% had significant active psychiatric conditions and 24% had significant co-morbid disease. A majority of patients co-infected with HCV/HIV had a IVDU history. Most co-infected patients were not eligible for HCV treatment. A majority of noncandidates had potentially modifiable psychosocial factors leading to nontreatment.     

HIV/HBV and HIV/HCV coinfection,and outcomes following highly active antiretroviral therapy

Objectives

To assess the prevalence and risk factors for HBV and HCV coinfection in the Australia HIV Observational Database (AHOD), and examine outcomes of HIV disease following initiation of highly active antiretroviral therapy (HAART).

Methods

Analyses were based on 2086 participants recruited to AHOD by September 2002. Of these, 1605 (77%) had been tested for HBV surface antigen, 1704 (82%) for anti‐HCV antibody and 1453 (70%) for both. Demographic and clinical predictors of HBV and HCV coinfection were examined. The impact of HBV and HCV coinfection on HIV disease progression was assessed by Kaplan‐Meier survival curves and Cox proportional hazard model of time to AIDS events and death.

Results

Among those tested, prevalence of HBV surface antigen and HCV antibody were 6.3% and 13.1%, respectively (4.8% and 10.7%, respectively, among the entire cohort). In multivariate analyses, the only independent risk factor for HIV/HBV coinfection was coinfection with HCV. Independent risk factors for HIV/HCV coinfection were HIV exposure category (with people who reported injecting drug use [MSM & IDU, IDU only] or receipt of blood or blood products at markedly increased risk) and HBV coinfection. HIV disease outcomes following first initiation of a HAART regimen were similar for HIV/HBV and HIV/HCV coinfected patients compared with HIV‐only patients in terms of AIDS‐free survival and detectable HIV virus during the first 12 months. However, patients coinfected with HIV/HCV appeared to have a poorer response to HAART in terms of CD4 count changes, with a CD4 count increase of 32 cells/μL (95% CI 1–67) less than HIV‐only patients.

Conclusions

Coinfection with HBV or HCV is relatively common among HIV‐infected participants in AHOD. HIV disease outcomes following HAART do not appear to be adversely affected by HBV/HCV coinfection, except for slightly poorer CD4 count responses in HIV/HCV coinfected patients.
