Immune compromise in patients with Down syndrome. A case series.

Down syndrome, or trisomy 21, has a higher mortality than the general population, mainly due to respiratory tract infections. The objective of this study was to describe immune compromise in a series of cases of patients with Down syndrome referred to the Pediatric Immunology Section due to recurrent infections or pathological laboratory findings between 6/1/2016 and 5/31/2022. Here we describe immune compromise in 24 patients.

[Recommendations for care, prevention of infections and chemoprophylaxis in inborn errors of immunity].

Inborn errors of immunity, previously named primary immunodeficiency are a heterogeneous group of genetic defects of different components of the immune system. Patients present high susceptibility to an only or several microorganisms, developing recurrent infections; the severity is related to the specific genetic type of immunity defect. The main strategy on the management of these illness is the prevention of infections.
