DIPREA: Systematic Screening for Primary Immunodeficiencies in Patients Hospitalized for Severe Infections in Intensive Care.
Study Details
Study Description
Brief Summary
Currently about 90 cases of infection in children are reported every year in pediatric intensive care, a disease considered to be the main cause of hospitalization of children. 16% of invasive pneumococcal infections are linked to a genetic abnormality in immunity. Herpetic encephalitis has become a model of genetic infectious disease, with new mutations identified in the TLR3 pathway. Severe infections are no longer the result of chance and can be the way to reveal a primary immune deficiency. In this context, the investigators propose to evaluate the incidence of hereditary immune deficiency after a systematic immunological screening in children admitted for a severe infection in pediatric intensive care unit (ICU).

Detailed Description
Severe infection requiring admission in intensive care unit (ICU) are not so rare. A retrospective pilot study conducted at Montpellier University Hospital Center (UHC) between 2013 and 2015 showed that 19.7% of the pediatric ICU admissions were related to a severe infection. An isolated severe infectious episode could be related to a hereditary immune deficiency (HID), even though there are no history of recurrent clinical signs and biological stigmata. For example, Gaschignard and colleagues considered that 16% of the invasive pneumococcal infections are related to a genetic defect of immunity (doi: 10.1093/cid/ciu274). Growing evidence has shown that severe infectious diseases occurring in childhood are attributed to inborn errors of immunity (doi: 10.1073/pnas.1521651112). While the nosology of severe infections has strong links to inherited immune deficiency that are rare diseases affecting less than 1 birth / 5000, there are no prospective studies that assessed the incidence of primary immune deficiencies in children who presented a severe infection.
