Peripheral immune cell markers in children with recurrent respiratory infections in the absence of primary immunodeficiency.

Peripheral immune cell markers in children with recurrent respiratory infections in the absence of primary immunodeficiency. Exp Ther Med. 2019 Sep;18(3):1693-1700 Authors: Munteanu AN, Surcel M, Huică RI, Isvoranu G, Constantin C, Pîrvu IR, Chifiriuc C, Ulmeanu C, Ursaciuc C, Neagu M Abstract The immune system of a child has a degree of immaturity that is maintained until 6-7 years of age. Immaturity may be due to age-related functional disorders in the immune response. A healthy child can contract a series of infections which contribute to the maturation of the immune system during the pre-pubertal period. If repeated infections with prolonged or severe complications occur during childhood, the presence of an immunodeficiency should then be considered. Much more frequent than primary immunodeficiency are recurrent infections (frequently involving the upper respiratory tract), which are less severe and occur under the conditions of an immune system with no apparent major defects. A child can present with 4 to 8 episodes of respiratory infections within a year, during the first 5 years of its life. The average duration of infection is 8 days and up to 2 weeks; if the child presents with 3 episodes of acute infections over a period of 6 months, the respiratory infections are then considered recurrent. The aim of this study was to identify the immunological changes or deviations that cause this clinical syndrome in children. For this...
