Since its emergence in China in 2019, the SARS-CoV-2 virus has affected all countries worldwide. The virus is easily transmitted from one person to another infected aerosols or contaminated surfaces. Unlike its counterparts, the prognosis of COVID-19 ranges from asymptomatic to critical disease or death. Several factors play a role in determining the severity of the disease in infected patients. Among others, is the pre-existence of an underlying medical condition such as diabetes, cancer, and others. Furthermore, although children are less prone to the severe form of the COVID-19 disease, they require attention due to the report of many atypical presentations of the infection, post-asymptomatic exposure. In the Middle East, little is known about the prognosis of the SARS-CoV-2 infection in high-risk categories, notably patients with diabetes, cancer, and pregnant women. The aim of this review is to summarize the current knowledge about this group of population in the middle eastern region as well as to highlight the gap in the literature. We have found that the majority of the papers were from the Gulf countries. Although, few studies were conducted; high-risk patients appear to have an increased risk of morbidity and mortality from COVID-19 compared to their counterparts. Higher levels of inflammatory markers, C-reactive protein, erythrocyte sedimentation rate, D-dimer, and ferritin levels were also observed. Children are often asymptomatic or present with atypical presentations. More studies should be conducted to determine the clinical biomarkers of COVID-19 in high-risk categories to help in patient risk stratification and management in the middle eastern population.
自2019年在中国出现以来,严重急性呼吸综合征冠状病毒2(SARS-CoV-2)已影响到全球所有国家。该病毒很容易通过受感染的气溶胶或受污染的表面在人与人之间传播。与其他病毒不同,冠状病毒病(COVID-19)的预后范围从无症状到重症疾病甚至死亡。有几个因素在决定感染患者疾病的严重程度方面起作用。其中包括潜在疾病的预先存在,如糖尿病、癌症等。此外,尽管儿童较少出现COVID-19重症形式,但由于有许多关于感染的非典型表现、无症状后暴露的报告,他们也需要关注。在中东地区,对于高危人群,特别是糖尿病患者、癌症患者和孕妇感染SARS-CoV-2的预后知之甚少。本综述的目的是总结中东地区关于这一人群的现有知识,并突出文献中的空白。我们发现大多数论文来自海湾国家。尽管进行的研究很少,但与其他人群相比,高危患者感染COVID-19后发病和死亡风险似乎增加。还观察到炎症标志物、C反应蛋白、红细胞沉降率、D-二聚体和铁蛋白水平较高。儿童通常无症状或表现为非典型症状。应该进行更多研究以确定高危人群中COVID-19的临床生物标志物,以帮助中东人群进行患者风险分层和管理。
