NCT03422614

Brief Summary

The pathophysiology of primary immunodeficiencies (PID), which encompass a broad range of different diseases with susceptibility to infection and/or a deregulated inflammatory response, is poorly understood. Available treatments are often not specific for a distinct target and might be associated with side effects. To elucidate pathophysiology of different PIDs, stool, urine, blood, tissue biopsies and/or bone marrow will be collected and analysed for anti-microbial activity and inflammatory response. In a second step, targeted treatment for different PIDs might be developed preclinically and ex vivo according to underlying pathophysiology.

Outcome Measures

Primary Outcomes (2)

  • Characterisation of cellular phenotype in different PIDs

    Immune cell subsets will be analysed for Surface marker Expression or cell activation pathways

    immediately after sampling of biological specimen or up to 10 years later from frozen samples

  • Characterisation of functional phenotype in different PIDs

    Immune cell subsets will be analysed for cytokine production or cell activation pathways

    immediately after sampling of biological specimen or up to 10 years later from frozen samples

Secondary Outcomes (1)

  • Identification of potential targets for pathophysiology-specific treatment, or for curative treatment such as gene therapy for different PIDs ex vivo

    immediately after sampling of biological specimen or up to 10 years later from frozen samples
