Living at high altitudes and living with prostatic illness are two different conditions closely related to a hypoxic environment. People at high altitudes exposed to acute, chronic or intermittent hypobaric hypoxia turn on several mechanisms at the system, cellular, and molecular level to cope with oxygen atmosphere scarcity maintaining the oxygen homeostasis. This exposure affects the whole organism and function of many systems, such as cardiovascular, respiratory, and reproductive. On the other hand, malignant prostate is related to the scarcity of oxygen in the tissue microenvironment due to its low availability and high consumption due to the swift cell proliferation rates. Based on the literature, this similarity in the oxygen scarcity suggests that hypobaric hypoxia, and other common factors between these two conditions, could be involved in the aggravation of the pathological prostatic status. However, there is still a lack of evidence in the association of this disease in males at high altitudes. This review aims to examine the possible mechanisms that hypobaric hypoxia might negatively add to the pathological prostate function in males who live and work at high altitudes. More profound investigations of hypobaric hypoxia's direct action on the prostate could help understand this exposure's effect and prevent worse prostate illness impact in males at high altitudes.
生活在高海拔地区和患有前列腺疾病是两种与低氧环境密切相关的不同情况。生活在高海拔地区的人,无论是急性、慢性还是间歇性地暴露于低压低氧环境中,都会在系统、细胞和分子水平上启动几种机制来应对氧气稀缺的情况,维持氧气的体内平衡。这种暴露会影响整个机体和许多系统的功能,如心血管、呼吸和生殖系统。另一方面,由于前列腺组织中氧气供应不足且消耗量大(由于细胞快速增殖),导致组织微环境缺氧,进而导致恶性前列腺疾病。根据文献,氧气稀缺的这种相似性表明,低压低氧以及这两种情况之间的其他常见因素,可能会加重病理性前列腺状态。然而,在高海拔地区男性中,这种疾病之间的关联仍缺乏证据。本综述旨在探讨低压低氧可能对生活和工作在高海拔地区的男性病理性前列腺功能产生负面影响的可能机制。更深入地研究低压低氧对前列腺的直接作用可能有助于了解这种暴露的影响,并防止高海拔地区男性前列腺疾病恶化的影响。
