Coronavirus disease 2019 (COVID-19) infection in pediatric patients with autoimmune disorders is an area of particular concern since autoimmune diseases can increase the risk of complications from the virus. However, as the infection rates were significantly higher in adults compared to children, this at-risk group of children was relatively underrepresented in COVID-19 research. The underlying inflammatory basis of autoimmune diseases and medications that affect the immune system, such as corticosteroids, could increase the risk of severe infection in this group of patients. COVID-19 could reportedly lead to a variety of alterations in the immune system. These alterations are plausibly dependent on the underlying immune-mediated diseases or prior use of immunomodulatory drugs. Patients administrating immunomodulatory agents, especially those with severe immune system dysregulation, can experience severe symptoms of COVID-19. Nonetheless, receiving immunosuppressive medications can benefit patients by preventing cytokine storm syndromes and lung tissue damage, threatening outcomes of COVID-19.
In this review, we sought to evaluate the currently available literature on the impact of autoimmune disease and its related therapeutic approaches on the COVID-19 infection course of disease in children and reflect on the gaps in the evidence and the need for further research in this field.
• The majority of children infected with COVID-19 demonstrate mild to moderate clinical manifestations compared to adults, whereas those children with pre-existing autoimmune conditions are at a greater risk for severe symptoms. •There is currently limited understanding of the pathophysiology and clinical outcomes of COVID-19 in pediatric patients with autoimmune disorders due to scattered reports and inadequate evidence.
• Generally, children with autoimmune disorders have more unfavorable outcomes than healthy children; yet, the severity is not extreme, and is highly dependent on their autoimmune disease type and severity, as well as the medication they are taking.
儿童自身免疫性疾病患者感染 2019 年冠状病毒病(COVID-19)是一个特别令人关注的领域,因为自身免疫性疾病会增加病毒引起并发症的风险。然而,由于成人感染率明显高于儿童,因此该高危儿童组在 COVID-19 研究中相对代表性不足。自身免疫性疾病的潜在炎症基础以及影响免疫系统的药物(如皮质类固醇)可能会增加该组患者发生严重感染的风险。据报道,COVID-19 可能导致免疫系统发生多种改变。这些改变可能依赖于潜在的免疫介导疾病或先前使用的免疫调节药物。接受免疫调节药物治疗的患者,尤其是那些严重免疫系统失调的患者,可能会出现严重的 COVID-19 症状。然而,免疫抑制药物的使用可以通过预防细胞因子风暴综合征和肺组织损伤来使患者受益,从而改善 COVID-19 的预后。
在这篇综述中,我们试图评估目前关于自身免疫性疾病及其相关治疗方法对儿童 COVID-19 感染病程的影响的文献,并思考这一领域证据中的差距和进一步研究的必要性。
与成年人相比,大多数感染 COVID-19 的儿童表现为轻度至中度临床表现,而那些患有先前存在的自身免疫性疾病的儿童发生严重症状的风险更高。由于零星报告和证据不足,目前对于儿科自身免疫性疾病患者 COVID-19 的病理生理学和临床结局知之甚少。
一般来说,患有自身免疫性疾病的儿童比健康儿童的预后更差;然而,严重程度并不极端,高度依赖于他们的自身免疫性疾病类型和严重程度以及他们正在服用的药物。
