Viruses are one of the simplest pathogenic organisms infecting the human body. Association between viral infections and endocrine system is complex and has not been fully studied. Viral infections can induce several physiological changes in the human endocrine system, resulting in cytokine mediated activation of hypothalamo-pituitary-adrenal axis to increase cortisol production, thus modulating the immune response. Further, many viral infections impact different endocrine organs, either by direct viral invasion or by systemic or local inflammation resulting in transient or permanent endocrinopathies; both hyper and hypofunction of endocrine organs may ensue. Viruses can encode production of specific viral proteins that have structural and functional homology to human hormones. Since endocrine hormones have immunoregulatory functions, endocrinopathies may alter the susceptibility of human body for viral infections. Recently the pandemic causing SARS 2 CoV infection has been shown to affect multiple endocrine organs through a variety of mechanisms, highlighting the significance of viral infection related endocrinopathies in morbidity and mortality. With improving understanding of viruses and their role in the human endocrine system, further research on this field would be required to explore new targets for prevention and treatment of endocrinopathies.

病毒是感染人体的最简单致病生物之一。病毒感染与内分泌系统之间的关联复杂,尚未得到充分研究。病毒感染可在人体内分泌系统中引发多种生理变化,导致细胞因子介导下丘脑 - 垂体 - 肾上腺轴激活,从而增加皮质醇的产生,进而调节免疫反应。此外,许多病毒感染会影响不同的内分泌器官,要么通过病毒直接侵袭,要么通过全身或局部炎症,导致短暂或永久性内分泌病变;内分泌器官的功能亢进和功能减退都可能出现。病毒可编码产生与人类激素具有结构和功能同源性的特定病毒蛋白。由于内分泌激素具有免疫调节功能,内分泌病变可能会改变人体对病毒感染的易感性。最近,导致新冠病毒感染的大流行已被证明通过多种机制影响多个内分泌器官,凸显了病毒感染相关内分泌病变在发病率和死亡率方面的重要性。随着对病毒及其在人体内分泌系统中作用的认识不断提高,需要对该领域进行进一步研究,以探索预防和治疗内分泌病变的新靶点。如需全面涵盖内分泌学的所有相关领域,请访问我们的在线免费网络文本,网址为WWW.ENDOTEXT.ORG。
