Due to impaired immune system, they are at a higher risk to develop a more severe COVID-19 course compared to general population.</p><p><strong>Objectives: </strong>Herein, we aimed to systematically review various aspects of IEI patients infected with SARS-CoV-2.

The majority of patients had critical infections (1013 cases, 27.8%). The highest frequency of critical and severe cases was observed in phenocopies of IEI (95.2%), defects in intrinsic and innate immunity (69.4%) and immune dysregulation (23.9%). 446 cases (12.2%) succumbed to the disease and the highest mortality was observed in IEI phenocopies (34.6%). COVID-19 frequency in immunodeficient patients was 11.9% (95% CI: 8.3 to 15.5%) with innate immunodeficiency having the highest COVID-19 frequency [34.1% (12.1 to 56.0%)].
