Infections in patients with primary immunodeficiencies in Pinar del Rio
Keywords:
INFECTIONS, DIAGNOSIS, PRIMARY IMMUNODEFICIENCY, INBORN ERRORS OF IMMUNITY.Abstract
Introduction: inborn errors of immunity are disorders whose cause is a genetic defect in one or more components of the immune system. Although the form of presentation varies according to the genetic defect, most of them present infectious diseases with recurrent and persistent characteristics.
Objective: to determine the prevalence of infectious processes in patients registered with diagnosis of Primary Immunodeficiency in the Immunology Service at Pepe Portilla Provincial Pediatric Teaching Hospital, Pinar del Rio in the period from 1994 to March 2021.
Methods: descriptive, cross-sectional study. The medical records of 125 patients diagnosed with immunodeficiencies registered in the database of the Immunology Service at Pepe Portilla Provincial Pediatric Teaching Hospital of Pinar del Rio were analyzed.
Results: the 85,6 % of patients presented diagnosis of some predominant antibody deficit. The predominant sex was male and the age range was from 6 to 10 years old. The most frequent infections were acute catarrhal pharyngotonsillitis (77,6 %), followed by pneumonia (58,4 %) and tonsillitis (56 %). Of the alarm signs related to infections only 4 were found in the patients in the registry.
Conclusions: susceptibility to infections is not necessarily the predominant clinical feature in primary immunodeficiencies, but the infectious phenotype is still the best suggestive indicator for a defect in immunity. Although it is necessary to propose new criteria for infectious manifestations that facilitate the probable diagnosis of immunodeficiency in general and by groups.
