To determine whether a chronic stressor (caregiving for a spouse with a progressive dementia) is associated with an impaired immune response to influenza virus vaccination, we compared 32 caregivers' vaccine responses with those of 32 sex-, age-, and socioeconomically matched control subjects. Caregivers showed a poorer antibody response following vaccination relative to control subjects as assessed by two independent methods, ELISA and hemagglutination inhibition. Caregivers also had lower levels of in vitro virus-specific-induced interleukin 2 levels and interleukin 1beta; interleukin 6 did not differ between groups. These data demonstrate that down-regulation of the immune response to influenza virus vaccination is associated with a chronic stressor in the elderly. These results could have implications for vulnerability to infection among older adults.
为了确定一种慢性应激源(照顾患有进行性痴呆的配偶)是否与流感病毒疫苗接种的免疫反应受损有关,我们将32名护理人员的疫苗反应与32名性别、年龄和社会经济状况相匹配的对照受试者的反应进行了比较。通过酶联免疫吸附测定(ELISA)和血凝抑制这两种独立方法评估发现,与对照受试者相比,护理人员接种疫苗后的抗体反应较差。护理人员体外病毒特异性诱导的白细胞介素2水平和白细胞介素1β水平也较低;两组之间白细胞介素6水平没有差异。这些数据表明,老年人对流感病毒疫苗接种的免疫反应下调与慢性应激源有关。这些结果可能对老年人的感染易感性有影响。
