黄病毒感染节肢动物和哺乳动物,它们的病理是一个相当大的全球健康问题。每年影响约4亿人。这些黄病毒的症状包括轻微的表现,如恶心,呕吐,和头痛更严重的病例,如出血,脑膜炎,小头畸形,肾,和肝功能衰竭。这篇综述旨在汇编由于登革热引起的感染而发生的形态学变化,黄热病,和寨卡病毒,以及描述这种黄病毒在肝脏中的可能作用机制。PRISMA指南用于搜索黄病毒与肝脏疾病相关的研究。两名独立审稿人选择了PubMed/Medline上的研究,WebofScience,和Scopus搜索平台。SYRCLE软件用于评价研究的质量。包括18篇实验文章。实验中常用的实验动物是猴子(5%),仓鼠(10%),鸡胚(10%),和小鼠(75%)。很明显,与黄病毒有很强的肝脏相互作用,发现的主要肝脏改变是脂肪变性,凋亡,坏死,出血,ALT和AST水平升高,和总胆红素.黄病毒感染,总的来说,引发促炎细胞因子的上调,导致线粒体的结构变化,从而激活细胞死亡的级联反应并促进胰岛素抵抗。大多数研究主要集中在登革热和黄热病病毒,而与寨卡病毒接触相关的发现仍然相对有限,需要进一步调查。
Flaviviruses infect arthropods and mammals and their pathologies are a considerable global health problem, affecting about 400 million people per year. The symptoms of these flaviviruses range from mild manifestations such as nausea, vomiting, and headache to more serious cases such as hemorrhage, meningitis, microcephaly, kidney, and liver failure. This
review aims to compile the morphological changes that occur due to infections caused by dengue, yellow fever, and Zika viruses, as well as to describe possible mechanisms of action of such flaviviruses in the liver. PRISMA guidelines were used to search for studies associating
flavivirus with liver disorders. Two independent reviewers selected the studies on PubMed/Medline, Web of Science, and Scopus search platforms. The SYRCLE software was used for the evaluation of the study\'s quality. Eighteen experimental articles were included. The experimental animals often used in experiments were monkeys (5 %), hamsters (10 %), chicken embryos (10 %), and mice (75 %). It is evident that there is a strong hepatic interaction with flaviviruses, and the main hepatic alterations found were steatosis, apoptosis, necrosis, hemorrhage, elevation of ALT and AST levels, and total bilirubin.
Flavivirus infection, in general, trigger an upregulation of pro-inflammatory cytokines, leading to structural changes in mitochondria that activate cascades of cellular death and promote insulin resistance. The majority of the studies primarily focus on dengue and yellow fever viruses, while the findings related to Zika virus exposure are still relatively limited and require further investigation.
