Brief Summary:
The COntAGIouS trial (COvid-19 Advanced Genetic and Immunologic Sampling; an in-depth characterization of the dynamic host immune response to coronavirus SARS-CoV-2) proposes a transdisciplinary approach to identify host factors resulting in hyper-susceptibility to SARS-CoV-2 infection, which is urgently needed for directed medical interventions.

Condition or disease Intervention/treatment
Coronavirus Infections Other: Patient sampling

Detailed Description:
The overall aim of this prospective study is to provide an in-depth characterization of clinical and immunological features of patients hospitalized in UZ Leuven because of SARS-CoV-2 infection. For this purpose, clinical data and blood, nasopharyngeal/rectal swab, and if safe, bronchoalveolar lavage (BAL) fluid and lung tissue samples will be collected from PCR- or CT-confirmed COVID-19 patients, with varying degrees of disease severity. Assessed characteristics will be compared between severe and non-severe COVID-19 patients, and between COVID-19 positive and negative ('control') patients.

Outcome Measures
Go to 
Top of Page Study Description Study Design Groups and Cohorts Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Clinical Features [ Time Frame: 6 months ]
    Description of clinical, laboratory and radiological features of illness and complications.

  2. Immune host response at systemic level [ Time Frame: 6 months ]
    Evaluation of dynamic host immune response at systemic level (immune signalling molecules in plasma, peripheral blood mononuclear cell isolation for advanced immunophenotyping and transcriptomics). Real-time analysis using CyTOF will be performed as screening, in combination with in-depth immunophenotyping.

  3. Immune host response at local level [ Time Frame: 6 months ]
    Evaluation of dynamic host immune response at systemic level (immune signalling molecules in plasma, peripheral blood mononuclear cell isolation for advanced immunophenotyping and transcriptomics).

  4. Host genetic variation [ Time Frame: 6 months ]
    Identification of host genetic variants that are associated with severity of disease.


Secondary Outcome Measures :
  1. Comparison severe and non-severe COVID-19 hospitalised patients [ Time Frame: 6 months ]
    Differences in baseline factors

  2. Comparison severe and non-severe COVID-19 hospitalised patients [ Time Frame: 6 months ]
    Differences in immune characteristics

  3. Correlation of findings with outcome [ Time Frame: 6 months ]
    Correlation of findings with outcome, aiming to identify early biomarkers of severe disease and putative targets for immunomodulatory therapy

  4. Correlation of immune profiling - microbiome [ Time Frame: 6 months ]
    Correlation of immune profiling with microbiome analysis of patients


Biospecimen Retention:   Samples With DNA
Blood, plasma, PBMC, BAL, lung tissue
