  • 简介:AbstractTransmission network analysis is a crucial evaluation tool aiming to explore the characteristics of the human immunodeficiency virus epidemic, develop evidence-based prevention strategies, and contribute to various areas of human immunodeficiency virus/acquired immunodeficiency syndrome prevention and control. Over recent decades, transmission networks have made tremendous strides in terms of modes, methods, applications, and various other aspects. Transmission network methods, including social, sexual, and molecular transmission networks, have played a pivotal role. Each transmission network research method has its advantages, as well as its limitations. In this study, we established a systematic review of these aforementioned transmission networks with respect to their definitions, applications, limitations, recent progress, and synthetic applications.

  • 简介:AbstractBackground:Human brucellosis is a neglected public health issue in China and reports of HIV-infected individuals complicated with brucellosis are rare. This report describes the case of an HIV-infected patient complicated with brucellosis. We want to raise awareness of clinical diagnosis of brucellosis among clinicians. Furthermore, we should be more concerned about cases with pyrexia of unknown origin, especially in non-epidemic areas of brucellosis in China.Case presentation:We encountered the case of a 31-year-old HIV-infected male with a CD4+ T lymphocyte count of approximately 300. On May 1, 2019, the patient had onset of non-specific caustic irregular fever with body temperature reaching 41.0 ℃. He was admitted to two medical institutions in Yunnan with pyrexia of unknown origin. Finally, on day 7 of hospitalization in the Public Health Clinical Medical Center in Chengdu City, he was diagnosed as having brucellosis infection based on blood culture results.Conclusions:This is the first reported case of brucellosis concomitant with HIV infection in China. Laboratories in infectious disease hospitals and category A level III hospitals in the southern provinces of China should be equipped with reagents for clinical diagnosis of brucellosis and to strengthen the awareness of brucellosis diagnosis in China. Secondly, in provinces with a high incidence of AIDS and brucellosis such as Xinjiang and Henan, it is recommended to implement a joint examination strategy to ensure the early detection, diagnosis, and treatment of this infection.

  • 简介:AbstractAntiretroviral therapy (ART) can effectively inhibit human immunodeficiency virus-1 (HIV-1) replication, but is not curative due to the existence of a stable viral latent reservoir harboring replication-competent proviruses. In order to reduce or eliminate the HIV-1 latent reservoir, characteristics of the latently infected cells need to be intensively studied, and a comprehensive understanding of the heterogenous nature of the latent reservoir will be critical to develop novel therapeutic strategies. Here, we discuss the different cell types and mechanisms contributing to the complexity and heterogeneity of HIV-1 latent reservoirs, and summarize the key challenges to the development of cure strategies for acquired immunodeficiency syndrome (AIDS).

  • 简介:摘要目的分析HIV-1/HCV合并感染者接受高效抗逆转录病毒治疗(Highly active antiretroviral therapy, HAART)后外周血单个核细胞(PBMC)中总HIV-1 DNA动态变化。方法回顾性分析2015年5月至2017年12月广州市第八人民医院收治的未进行抗HCV治疗的30例HIV-1/HCV合并感染初治患者(合并感染组),以同期收治的42例HIV-1单一感染初治患者为单一感染组。观察两组HAART后12、24、48、72及96周的病毒学和免疫学应答情况,PBMC中总HIV-1 DNA变化规律及其与外周血HIV-1 RNA、外周血T淋巴细胞亚群的关系。应用SPSS 22.0统计软件对数据进行分析。结果两组患者HAART后血浆HIV-1病毒抑制率、CD4+ T淋巴细胞计数及CD4+/CD8+T淋巴细胞比值均升高,PBMC中总HIV-1 DNA水平均降低。HIV-1/HCV合并感染组HAART 72周时的HIV-1病毒抑制率低于HIV-1单一感染组(χ2=7.93,P<0.01)。HIV-1/HCV合并感染组HAART 12、24、72、96周时的CD4+T淋巴细胞计数均低于HIV-1单一感染组(U=313.50、329.00、286.00和204.50,P<0.05或<0.01)。HIV-1/HCV合并感染组HAART 48周时的CD4+/CD8+T淋巴细胞比值低于HIV-1单一感染组(U=294.50,P<0.05)。HIV-1/HCV合并感染者基线和HAART 12周时PBMC总HIV-1 DNA低于HIV-1单一感染者(U=362.00和359.00,P<0.01或<0.05)。两组患者PBMC总HIV-1 DNA与HIV-1 RNA、CD4+/CD8+T淋巴细胞比值均无相关性(P值均>0.05),HIV-1/HCV合并感染组患者PBMC中总HIV-1 DNA与CD4+T淋巴细胞计数无相关性(b=-0.001,P>0.05),而HIV-1单一感染组患者PBMC中总HIV-1 DNA与CD4+T淋巴细胞计数呈负相关(b=-0.001,P<0.05)。结论HIV-1/HCV合并感染者HAART后外周血总HIV-1 DNA水平下降,合并HCV感染延缓HIV-1感染者HAART后总HIV-1 DNA的下降。

  • 简介:AbstractBackground:After the scale-up of antiretroviral therapy (ART) for HIV infected people, increasing numbers of patients have pretreatment drug resistance (PDR). In this study, the prevalence of PDR was evaluated in adults initiating antiretroviral therapy in China.Methods:Blood samples were obtained from 1943 patients who initiated antiretroviral therapy (ART) in 2017 from 13 provinces or cities in China. Pol sequences were used to analyze drug resistance and construct transmission networks. Logistic regression model was used to estimate the potential factors associated with PDR.Results:In total, 1711 eligible patients (76.0% male; 87.8% aged ≥ 25 years) were included, of which 117 (6.8%) had PDR. The highest rates of PDR were 12.2% in Liangshan Prefecture of Sichuan and 9.3 and 8.9% in Dehong and Lincang Prefecture of Yunnan. A multivariate logistic regression analysis revealed that PDR was significantly higher among intravenous drug users (adjusted Odds Ratio (aOR) = 2.64, 95% CI: 1.57–4.44) and individuals from Liangshan, Dehong, and Lincang (aOR= 2.04, 95% CI: 1.26–3.30). In total, 754 sequences were used to generate 164 transmission networks. Five transmission networks had two or three sequences containing the same mutations, two networks contained subjects from Liangshan, and one network contained subjects from Dehong.Conclusions:Overall, the PDR prevalence was moderate, with a particularly high prevalence in areas with severe HIV epidemics. These results indicate the importance of continuous PDR monitoring in patients initiating antiretroviral therapy.

  • 简介:AbstractThe prevalence of asymptomatic cryptococcal antigenemia (ACA) in human immunodeficiency virus (HIV) infected individuals has been observed to be elevated. The prevalence of ACA ranges from 1.3% to 13%, with different rates of prevalence in various regions of the world. We reviewed studies conducted internationally, and also referred to two established expert consensus guideline documents published in China, and we have concluded that Chinese HIV-infected patients should undergo cryptococcal antigen screening when CD4+ T-cell counts fall below 200 cells/μL and that the recommended treatment regimen for these patients follow current World Health Organization guidelines, although it is likely that this recommendation may change in the future. Early screening and optimized preemptive treatment for ACA is likely to help decrease the incidence of cryptococcosis, and is lifesaving. Further studies are warranted to explore issues related to the optimal management of ACA.
