Since serological donor-screening tests for HIV were introduced in 1985, the safety of donated blood components has improved dramatically. However, these tests do not completely prevent the risk of transfusion-associated HIV infection related to the use of blood donated during the pre-seroconversion window period. Testing based on nucleic acid amplification is being implemented to screen for HIV-infected blood donated during this period, which has reduced the probability of transmitting HIV through transfusion by shortening the window period. This article describes a case of acute HIV-1 infection, detected using a nucleic acid amplification test (NAT) in a repeat blood donor who donated during the pre-seroconversion window period and whose antigen and anti-HIV antibody expression was observed after molecular marker detection. In addition, the possible route of infection is discussed based on the patient's history, and finally, the need for NAT technology for blood donor screening is emphasized.
自 1985 年引入血清学供者筛查试验检测 HIV 以来,捐献血液成分的安全性已得到显著改善。然而,这些检测并不能完全预防与使用窗口期期间捐献的血液相关的输血相关 HIV 感染风险。目前正在实施基于核酸扩增的检测来筛查窗口期期间捐献的 HIV 感染血液,这通过缩短窗口期降低了通过输血传播 HIV 的概率。本文描述了一例急性 HIV-1 感染病例,该病例是通过对窗口期期间重复献血的供者进行核酸扩增检测(NAT)检测到的,该供者的抗原和抗 HIV 抗体表达在分子标志物检测后观察到。此外,根据患者的病史讨论了可能的感染途径,并最终强调了 NAT 技术在献血者筛查中的必要性。
