Abstract

Aging has a profound impact on the immune system, leading to a gradual decline in its function and increased systemic inflammation, collectively known as immunosenescence and inflammaging. These changes make older adults more susceptible to infections, including COVID-19, and contribute to worse clinical outcomes, such as higher morbidity and mortality rates. This review explores immunological changes associated with aging, including impaired innate immune responses, reduced T- and B-cell function, and altered cytokine profiles. A comprehensive literature search identified relevant studies on the topic, and inclusion criteria focused on studies addressing age-related immune changes and their impact on responses to COVID-19. The findings underscore the need for targeted healthcare strategies to mitigate the negative effects of aging on immunity and improve immune resilience, and ultimately clinical outcomes and quality of life for this vulnerable population.

与年龄相关的免疫参数变化:对老年人COVID-19免疫反应的影响
衰老对免疫系统有深远的影响,导致其功能逐渐下降,全身性炎症增加,统称为免疫衰老和炎症。这些变化使老年人更容易感染包括COVID-19在内的感染,并导致更糟糕的临床结果,如更高的发病率和死亡率。这篇综述探讨了与衰老相关的免疫变化,包括先天免疫反应受损、T细胞和b细胞功能降低以及细胞因子谱改变。综合文献检索确定了与该主题相关的研究,纳入标准侧重于研究与年龄相关的免疫变化及其对COVID-19反应的影响。研究结果强调了有针对性的医疗保健策略的必要性,以减轻衰老对免疫力的负面影响,提高免疫弹性,并最终改善这一弱势群体的临床结果和生活质量。
