迫切需要创新的方法来减少艾滋病毒和HCV等血源性病原体在注射毒品者(PWID)中的传播。我们调查了获得非致病性血源性病毒如环状病毒和pegiviruses的PWID是否可能有更大的风险获得血源性病原体。后来获得HCV的PWID在血浆中积累了比未获得HCV感染的匹配对照更多的非致病性病毒。此外,对这些非致病性病毒序列的系统发育分析揭示了吸毒网络。在这里,我们首先在巴尔的摩发现,并在旧金山弗朗西斯科证实,非致病性病毒在PWID中的积累是随后获得致病性病毒的先兆,这一知识可能会指导公共卫生资源的优先次序,以打击艾滋病毒和丙型肝炎病毒。血液传播感染,如HCV和HIV,是一个问题,特别是在注射毒品的人群中。在这里,作者描述并在观察性PWID队列中证实,血浆中具有更多非致病性病毒的人比具有较少这些非致病性病毒的PWID更有可能后来获得HCV。
There is an urgent need for innovative methods to reduce transmission of bloodborne pathogens like HIV and HCV among people who inject drugs (PWID). We investigate if PWID who acquire non-pathogenic bloodborne viruses like anelloviruses and pegiviruses might be at greater risk of acquiring a bloodborne pathogen. PWID who later acquire HCV accumulate more non-pathogenic viruses in plasma than matched controls who do not acquire HCV infection. Additionally, phylogenetic analysis of those non-pathogenic virus sequences reveals drug use networks. Here we find first in Baltimore and confirm in San Francisco that the accumulation of non-pathogenic viruses in PWID is a harbinger for subsequent acquisition of pathogenic viruses, knowledge that may guide the prioritization of the public health resources to combat HIV and HCV. Spread of bloodborne infections, such as HCV and HIV, is a problem, particularly amongst people who inject drugs (PWID). Here, the authors describe and then confirm in observational PWID cohorts that those with more non-pathogenic viruses in plasma were more likely later to acquire HCV than PWID who had fewer of these non-pathogenic viruses.
