Abstract:
Objective:To explore the clinical manifestations, genetic disorder, prognosis of 14 neonates with primary immunodeficiency disease(PID).Methods:A total of 14 newborns with PID admitted to Department of Neonatology at Beijing Children′s Hospital from January 2017 to December 2019 were enrolled for retrospective analysis, focusing on their clinical manifestation, peripheral blood cell examnations, gene mutation, and outcomes after hemotopoietic stem cell transplantation(HSCT).Results:The average gestational age of the newborn was (38.6±1.2) weeks, the birth weight was (3 265±325)g, and the median diagnosis time was 57.5 days.Fourteen newborns with PID were diagnosed by whole exome sequencing as chronic granuloma (6/14), DiGeogre syndrome (3/14), Wiskott-Aldrich syndrome (2/14), severe combined immunodeficiency (2/14) and selective IgA deficiency (1/14). Regarding the clinical manifestations, fever, pneumounia and colitis accounted for 7/14, the decrease of T lymphocytes in peripheral blood accounted for 6/14, and the decrease of B lymphocytes accounted for 5/14.The absolute value of eosinophils increased (>500 cells/mm 3) accounted for 12/14, of which moderately increased (1 500 to 5 000 cells/mm 3) accounted for 5/12, and the absolute value of monocytes increased (median>1.5×10 9/L) accounted for 7/14.Follow-up children received HSCT accounted for 7/14, and the median time of receiving transplantation was 330 days after birth.By the time of follow-up, the primary disease resolved after HSCT accounted for 5/7, and the survival rate was 85.7%.Among them, two children with chronic granulomatosis were diagnosed with inflammatory bowel disease before transplantation, and the primary disease improved after HSCT.Three-quarters of the deaths had inflammatory bowel disease-like manifestations and died of infectious shock. Conclusion:The clinical manifestations of children with PID during the neonatal period are not specific.The manifestations of colitis need more attention.Some of the newborns with PID will evolve into inflammatory bowel disease or have inflammatory bowel disease-like manifestations or even die of it.HSCT is a fundamental treatment for the primary disease.
