研究人员发现另一种影响六成长新冠患者的并发症
近日《英国皇家医学会杂志》（Journal of the Royal Society of Medicine）发布的一项新研究显示，近六成长新冠患者经历这种偶尔致命的疾病一年后会出现器官损伤。
伦敦的研究人员查看了536名长新冠患者，其中只有13%刚开始就因新冠住院。多数患者，也即占62%的患者感染新冠六个月后确诊器官损伤。研究中多数长新冠患者，也即近六成人一年后仍存在器官损伤。此外，超过四分之一的患者出现两个或两个以上器官损伤。
伦敦大学学院健康信息学研究所（University College London Institute of Health Informatics）临床数据科学教授阿米塔瓦·班纳吉在介绍这一发现的新闻稿中表示，长新冠症状似乎经常出现在年轻人和女性身上，且多为单器官损伤。
“几项研究证实，长新冠患者的症状可持续达一年，”班纳吉说。“现在补充了新情况，五分之三长新冠患者至少一个器官损伤，四分之一患者两个或两个以上器官损伤，有些没有症状。”
虽然采取了血液检测和核磁共振成像，研究人员还是无法确定新冠病毒究竟如何导致长新冠症状。目前针对长新冠并无正式诊断标准。哪怕只是长新冠的定义，也会因交流对象不同有所差别。通常来说长新冠是指新冠感染期间开始或感染后出现，持续数周或数月的新症状。
专家表示，从持续咳嗽、疲劳到耳朵麻木，以及“大脑着火”的感觉，已知症状达200多种，可见长新冠并非一种症状，而是多症状并存。
一些人认为，最恰当的长新冠定义为感染新冠后出现的慢性疲劳综合症，与感染疱疹、莱姆病和埃博拉等病毒后可能出现的综合症类似。
一些专家表示，器官损伤等新冠后其他并发症不应定义为长新冠，更适合纳入范围更大的新冠后综合症（PASC）范畴。PASC也称为急性新冠后遗症，涵盖罹患新冠后的多种影响，从慢性疲劳症状和引发的心脏疾病，再到持续肺损伤和奇怪的新症状等，如小便失禁、瘙痒和皮肤损伤等。
1月26日凯撒家庭基金会（Kaiser Family Foundation）援引美国疾病预防控制中心数据发布的一份报告显示，截至1月16日，美国15%的成年人报告在疫情中某阶段出现长新冠症状，6%的成年人报告称持续存在症状。
报告称，感染过新冠且报告仍存在长新冠症状的美国人比例已从6月的19%降至1月的11%。（财富中文网）

Nearly 60% of patients with long COVID had organ impairment a year after catching the sometimes deadly disease, according to a new study released Tuesday by the Journal of the Royal Society of Medicine.
London-based researchers examined 536 long COVID patients, only 13% of whom were initially hospitalized with COVID. The majority—62%—were diagnosed with organ impairment six months after having COVID. The vast majority—nearly 60% of all long COVID patients studied—continued to experience organ impairment a year later. What’s more, more than a quarter saw impairment of two organs or more.
Long COVID symptoms seemed generally associated with being young and female, and having single-organ impairment, Amitava Banerjee, professor of clinical data science at the University College London Institute of Health Informatics, said in a news release on the findings.
“Several studies confirm persistence of symptoms in individuals with long COVID up to one year,” Banerjee said. “We now add that three in five people with long COVID have impairment in at least one organ, and one in four have impairment in two or more organs—in some cases without symptoms.”
The researchers were unable to determine exactly what about the COVID virus was causing long COVID symptoms, even after performing blood tests and MRIs. Currently, there are no official diagnostic criteria for long COVID. Even the definition of the condition varies depending on whom you talk to, though it’s generally considered to consist of new symptoms that start during a COVID infection or appear after one, and persist for weeks or months.
With more than 200 symptoms identified—from lingering cough and fatigue to ear numbness and a sensation of “brain on fire”—long COVID is undoubtedly not one but multiple conditions, experts say.
True long COVID, some contend, is best defined as a chronic-fatigue-syndrome-like condition that develops after a COVID infection, similar to other post-viral syndromes that can occur after an infection with herpes, Lyme disease, and Ebola, among others.
Other post-COVID complications like organ damage should not be defined as long COVID and better fit into the larger umbrella category of PASC, some experts say. Also known as post-acute sequelae of COVID-19, the term is used to encompass a wide variety of COVID consequences, from chronic-fatigue-like symptoms and subsequent heart disease to lasting lung damage and odd new symptoms like urinary incontinence, itching, and skin lesions.
As of Jan. 16, 15% of U.S. adults reported having long COVID symptoms at some point in the pandemic, and 6% reported lingering symptoms, according to a Jan. 26 report by the Kaiser Family Foundation, citing data from the U.S. Centers for Disease Control and Prevention.
The percent of Americans who’ve experienced COVID and still report long COVID symptoms dropped from 19% in June to 11% in January, according to the report.
