Brief Summary:
In this study (i) the host genome to identify susceptibility regions of infection, inflammation, and host defense, (ii) host response to Severe Acute Respiratory Syndrome-Corona-Virus-2 (SARS-CoV-2) infection, and (iii) viral sequence composition to define viral sequences which may be correlated with disease severity in addition to the metagenome of the throat swab will be analysed .

Detailed Description:

This study aims to recruit adult persons with diagnostically confirmed Corona-Virus- Disease-19 (COVID-19) infection and with different disease manifestation who are included into diagnostic or therapeutic care at the University Hospital Tübingen (UKT).

The COVID-19 Next-Generation-Sequencing (NGS) study aims to cover as many patients in Germany as possible. It is expected to include in Phase 1 (pilot study): 250 patients with different disease manifestation (extreme phenotypes) and individual risk factors by whole genome analysis Phase 2 (verification study): 1.000 clinically well-defined patients to ensure a broader range of overlapping phenotypes, to verify data from the pilot study.

Phase 3 (confirmation study): > 10.000 patients to increase the power (anticipated).

Arm Intervention/treatment
Host Genome Analysis
For 150 patients from the extreme phenotypes - complementary to Whole Genome Analysis of each patient also Whole Transcriptome will performed Analysis; DNA methylation analysis using EPIC arrays will be performed in the pilot study (phase 1). Identically, in phase 2 starting from month 4, will be generated WGS, Whole transcriptome sequencing (WTS), and methylation data of the 500 patients. Epigenetic changes are likely to occur upon Corona infection. Subsequently, genome and epigenome data with RNA expression pattern will be correlated.
Genetic: Whole Genome Analysis
Whole Genome Analysis with whole transcriptome analysis and deoxyribonucleic acid (DNA) methylation analysis using Methylation beadchip (EPIC) arrays

Host Response to SARS-CoV-2 Infection
Focus on longitudinal analysis of TCR repertoire of CD4+ and CD8+ T cells from blood samples (PBMCs) from clinically characterized patients (n = 24). The bulk- T-cell receptor (TCR) sequencing will be performed at different time points during the course of disease progression and recovery.
Genetic: T-cell receptor (TCR) repertoire
Longitudinal analysis of TCR repertoire of Cluster of Differentiation 4+ (CD4+) and CD8+ T cells from blood samples (Peripheral Blood Mononuclear Cells, PBMCs) from clinically characterized patients

Viral Sequence Composition
The Severe Acute Respiratory Syndrome-Corona Virus-2 (SARS-CoV-2) viral composition is determined by Next Generation sequencing (different protocols for enrichment are available, and are currently being tested to successfully analyse the virus from different isolates). It is known that SARS-CoV-2 sequence is changing at least one position every second passing from person to person. Numerous variants have been described deriving from 3 different ancestral viruses (named A, B, and C) reflecting different distributions in East Asia, Europeans and Americans. At it is anticipated that other (super)infections may add to the severity of the infection and disease course, the entire metagenome of the throat is being sequenced and analyzed as well.
Genetic: SARS-CoV-2 viral composition
Determined by Next Generation sequencing

Primary Outcome Measures :
  1. Viral evolution [ Time Frame: Day 1, Day 3-5, Day 7-9, 48 hours after recovery ]
    The change in the genetic makeup of a virus population (measured in numbers) as the viruses mutate and multiply over time at different time points

Secondary Outcome Measures :
  1. Immune response [ Time Frame: Day 1, Day 3-5, Day 7-9, 48 hours after recovery ]
    CD4+ and CD8+ T cells from blood (per µl) at different time points measured

  2. Disease severity [ Time Frame: Day 1, Day 3-5, Day 7-9, 48 hours after recovery ]

    Clinical classification according to severity:

    • Light and uncomplicated (mild symptoms)
    • Moderate (mild pneumonia)
    • Severe pneumonia
    • Critical (Acute Respiratory Distress Syndrome (ARDS), sepsis, septic shock) Evaluated at several time points
