什么是“COVID脚趾”?皮肤科医生表示，足部病变可能是也可能不是新型冠状病毒症状
在禁闭期间赤脚走路或久坐会导致这种症状吗?
随着COVID-19继续在美国蔓延，更多的潜力和确认疾病的症状已经被发现了。除了最常见的症状(发热那呼吸急促， 和干咳)，新冠肺炎还表现为结膜炎(又名，红眼病)，皮疹， 和像腹泻等消化问题．最近几个月，皮肤科医生一直在调查被称为“COVID脚趾”的冠状病毒感染的另一个潜在迹象。
最初来自4月9日共享的新闻稿，由西班牙的摩托车官方大学大学总理分享，后富牛犬开始“注册众多病人，主要是儿童和年轻人，他们脚上有小皮肤病学病变” -有时在没有其他Covid-19症状的情况下;有时在出现其他症状之前。根据理事会的那些病变是“紫色”，通常出现在脚趾的尖端周围，但它们通常会愈合而不留下皮肤上的标记。理事会将标志与那些结果的标志进行了比较水痘那麻疹，或pernio(暴露于极冷温度后出现的小损伤)。
在四月份，国际足病医师联合会发布了一个案例研究，详细说明了类似的发现，描述了一个13岁的男孩，突然患上两只脚的病变。两天后，他介绍了一般的Covid-19症状 - 发烧，肌肉疼痛，和头痛 - 随着“脚病变的强烈瘙痒和燃烧”。这个男孩从未测试过Covid-19，也不是任何其他家庭成员，但他的姐姐和母亲在男孩的症状出现之前表现出冠状病毒的症状。每周报告，男孩的脚病变开始在一周内清除。这美国皮肤病学会甚至有自己的皮肤问题登记册，可能与COVID-19有关，包括“COVID脚趾”，以便更好地了解两者之间的联系。
然而，最近，一部小型研究呼吁质疑这种病变是否是病毒的症状。
比利时的一个研究小组报道JAMA皮肤科，描述了31种少年和年轻成年患者，脚趾和/或手指上有紫色的斑块。没有测试SARS-COV-2病毒的阳性，这会导致疾病，并且所有对病毒的抗体都是阴性的。研究人员怀疑这些患者的皮肤症状可能是由于大流行产生的社区遏制和锁定措施。大多数（64％）报告报告的身体活动减少，更多的时间在从家里工作或家庭学校工作时在久坐状态下花费更多的时间。值得注意的是，大多数患者表明他们赤脚或在袜子里大部分时间都保持着。
同样，西班牙的研究人员评估了20名儿童和青少年，他们在脚和/或手上开发了紫色的皮疹。没有Covid-19基于鼻拭子和血液检测的感染症状或症状。写作JAMA皮肤科报告的作者说，一种可能性是，这些孩子的症状可能与赤脚或只穿袜子和很少进行体育活动的隔离经历有关。
当然，很多遗骸。需要较大，设计良好的涉及对照组的研究，以解决这些脚趾病变和冠状病毒感染之间的任何可能的相关性。

虽然目前尚不清楚为什么Covid-19患者可能发生的原因，纳纳南赛迪，MD，托马斯杰斐逊大学的董事会认证皮肤科医师表示，它可能会与病毒刺激炎症有关。“它可以是手指或脚趾的局部炎症。或者，它可以是导致循环中微小的炎症，”她说。她还指出，那些非常生病的人中已经看到血液凝固的增加。“他们在无症状患者中看到这一点，但也患病患者，”Saedi博士说。
在新闻发布中西北医学，皮肤科医生艾米·帕尔勒，也指出，反应可能是免疫应答，再次将其与Pernio相似。“Pernio，这种情况类似但是对寒冷的反应，涉及夹紧这些小血管 - 并且我们认为这可能发生这种情况，响应于炎症，可能导致对Covid-19病毒的反应的一部分，“ 她说。
桑托耶特，萨洛瓦皮肤科董事会认证的皮肤科医生和首席医学官员同意，同意，补充说它也可能与对Covid-19感染的免疫系统反应有关。“特定的免疫系统反应...... [那]可能会迅速发展到Covid-19并导致这些奇怪的结果，”他解释道。
莱恩博士和萨迪博士补充说，“COVID脚趾”主要出现在儿童和年轻人身上，这可能也表明这是一种免疫反应。“儿童和年轻人有更强的免疫系统，他们有很强的局部反应，”Saedi博士说。莱恩博士补充说，“科学界假设，‘COVID脚趾’可能是强大的免疫反应的迹象，也可能是年轻人往往比成年人的感染过程更温和的原因。”
现在,并不是完全清楚脚病变有关COVID-19肯定,“但当现在常见的大流行期间,发生在无症状或轻微症状的患者,似乎太多的巧合不是病毒对患者的表现在他们的青少年和20多岁,”佩拉博士说。西班牙官方足病学院总理事会呼应了这一声明，称“(它)敦促学院及其成员保持高度警惕，因为这可能是发现COVID-19的迹象，有助于避免传播。”
最终，根据萨迪博士的说法，“COVID脚趾”仍然是一个问号。“就像这种病毒的所有方面一样，有很多东西需要了解，”她说，但皮肤科医生和患者都应该意识到潜在的症状。和往常一样，如果你注意到这种新症状，或任何其他与covid -19相关的症状，最好打电话给你的医生，询问下一步的诊断和治疗。
