Brief Summary

In December 2019, the first people got infected with COVID-19 in Wuhan, China. Within weeks, this highly infectious disease spread all over the world. Nearly one year later everyone is still trying to battle this disease and facing the consequences it causes. What became clear is that the disease and its severity differs largely between infected people. However, knowledge about who will experience severe COVID-19 and who does not is still unclear. Therefore, the aim of this study is to investigate the prognostic value of certain parameters (mtDNA and CT radiomics signature) for the severity of COVID-19.

Detailed Description

In December 2019, the first cases of coronavirus disease 2019 (COVID-19) were diagnosed in Wuhan, China. Within a couple of weeks, the highly contagious disease spread across the world, requiring rapid and drastic measures, unparalleled in recent decades. Currently, there have been approximately 97.8 million cases, including 2.1 million deaths, reported to the WHO (website accessed January 25th, 2021, https://covid19.who.int). Data from published epidemiology and virologic studies show that the virus is mainly passed on by respiratory droplets, by direct contact with infected people, or by contact with contaminated objects and surfaces. The severity of the disease greatly differs between people. It ranges from non-symptomatic contamination or minor symptoms, such as a cold or sore throat, to life-threatening pneumonia and death. Especially, the elderly population and people with underlying comorbidities are vulnerable and experience more severe symptoms. In addition, studies have shown that males have a higher mortality risk.

COVID-19 is currently diagnosed using reverse-transcription polymerase chain reaction (RT-PCR). In the beginning of the pandemic the use of chest computed tomography (CT) was more common, since CT can capture imaging features from the lung associated with COVID-19 early in the course of the disease. However, performing a CT-can takes remarkably longer than current RT-PCR tests. While the epidemic continues, the consequences are slowly becoming more apparent. As the true population infection rate is unknown, the proportion of patients requiring hospital admission is difficult to estimate. In a meta-analysis including 1481 unique publications a pooled rate of ICU admission of 10.9% and the pooled rate of mortality was 4.3%. The negative effects of an ICU stay strongly depend on the length of the stay and include, but are not limited to, risk of lung emboly, severe muscle loss, dysphagia and psychological problems, often necessitating a long period of rehabilitation.

To minimize long-term health consequences early prognosis of the severity of the disease would be beneficial. The link between the severity of COVID-19 and mitochondrial DNA (mtDNA), Nuclear SNPs, imaging features and radiomics has not been studied yet. However, literature about mechanistic insights in the functioning of the immune system and its link to genetic variation, including mtDNA, are promising. In addition, studies focusing on imaging features and radiomics have yielded interesting findings.
