High levels of immune activation are reported for people who inject drugs. Studies of the relationship between injection behaviors and immune activation have yielded mixed results, in part due to lack of control for hepatitis C virus in analyses. This study, of 48 HIV-seronegative people who inject drugs, examines this relationship controlling for hepatitis C virus viremia. Frequency of injection was positively related to markers of immune activation (soluble CD14, %CD8CD38HLADR T cells), as was duration of injection (high-specificity C-reactive protein and D-dimer). Sharing injection equipment was not related to markers studied. Findings suggest that efforts to encourage injection cessation or reduction in frequency can have positive health benefits through reducing immune activation.
据报道,注射毒品者的免疫激活水平较高。对注射行为与免疫激活之间关系的研究结果不一,部分原因是分析中未对丙型肝炎病毒进行控制。这项针对48名注射毒品的HIV血清阴性者的研究,在控制丙型肝炎病毒血症的情况下考察了这种关系。注射频率与免疫激活标志物(可溶性CD14、%CD8CD38HLADR T细胞)呈正相关,注射持续时间(高特异性C反应蛋白和D-二聚体)也与之呈正相关。共用注射器具与所研究的标志物无关。研究结果表明,鼓励停止注射或减少注射频率的努力可通过降低免疫激活而带来积极的健康益处。
