Effective therapies have transformed HIV infection into a chronic disease, and new problems are arising related to aging. This article reviews the aging process, age-related deficit accumulation and frailty, and how these might be affected by chronic HIV infection.
Aging is characterized by acceleration in the rate of unrepaired physiologic damage an organism accumulates. HIV infection is associated with many factors that might affect the aging process, including extrinsic behavioral risk factors and co-infections, and multiple intrinsic factors, including intercellular communication, inflammation, and coagulation pathways. Whether each factor affects the aging process, they likely result in an increase in the risk of adverse health outcomes, and so give rise to frailty, likely with several clinical manifestations.
Age-related deficit accumulation is influenced by both the background or environmental rate of insults an organism sustains and the efficacy of intrinsic damage control and repair mechanisms. Both processes are likely affected in people living with HIV infection.
有效的治疗方法已将HIV感染转变为一种慢性疾病,并且与衰老相关的新问题正在出现。本文综述了衰老过程、与年龄相关的缺陷积累和衰弱,以及慢性HIV感染可能如何影响这些方面。
衰老的特征是生物体积累的未修复生理损伤速率加快。HIV感染与许多可能影响衰老过程的因素有关,包括外在行为危险因素和合并感染,以及多种内在因素,包括细胞间通讯、炎症和凝血途径。无论每个因素是否影响衰老过程,它们都可能导致不良健康结局风险增加,从而引发衰弱,可能伴有多种临床表现。
与年龄相关的缺陷积累受到生物体所遭受的背景或环境损伤速率以及内在损伤控制和修复机制功效的影响。这两个过程在HIV感染者中可能都会受到影响。
