环境污染物与艾滋病患者的发病及预后研究进展

Research Progress on Environmental Pollutants and the Pathogenesis and Prognosis of HIV/AIDS Patients

虽然高效抗逆转录病毒治疗已经把艾滋病变成了能够长期管理的慢性传染病,可是患者预后的个体差异比较明显。近些年不良环境暴露被发现是影响艾滋病生存质量、免疫重建、疾病进展的重要外源性因素。环境污染物作为广泛存在而且有可预防的外部风险因素,有着低剂量、长时程、多途径暴露的特点,能够通过免疫毒性、氧化应激、慢性炎症激活、代谢紊乱等多种通路,干扰艾滋病患者的免疫重建进程和病毒抑制效果,进而影响其疾病进展、远期生存结局。本文系统综述了大气污染物、重金属、黄曲霉素、多环芳烃等典型环境污染物与艾滋病患者发病进展及预后转归的关联,深入分析人群易感性差异和当前研究存在的局限,可为优化HIV/AIDS患者的健康管理策略、降低环境相关健康风险、改善患者远期预后给予理论参考和实践依据。
Although highly active antiretroviral therapy has turned AIDS into a chronic infectious disease that can be managed for a long time, the individual differences in the prognosis of patients are obvious. In recent years, adverse environmental exposure has been found to be an important exogenous factor affecting the quality of life, immune reconstruction and disease progression of AIDS. As an external risk factor that exists and has potential intervention, environmental pollutants have the characteristics of low-dose, long-term and multi-channel exposure. They can interfere with the immune reconstruction process and virus inhibition effect of AIDS patients through various pathways such as immunotoxicity, oxidative stress, chronic inflammation activation, and metabolic disorders, thereby affecting their disease progression and long-term survival outcomes. This article systematically reviews the association between typical environmental pollutants such as air pollutants, heavy metals, aflatoxins, and polycyclic aromatic hydrocarbons and the progression and prognosis of AIDS patients. In-depth analysis of the differences in population susceptibility and the limitations of current research can provide theoretical reference and practical basis for optimizing the health management strategies of HIV / AIDS patients, reducing environmental-related health risks, and improving the long-term prognosis of patients.
