Abstract:
Objective:To study the clinical characteristics of neonatal leukemoid reaction (NLR).Methods:The newborns with NLR admitted to the neonatal intensive care unit of the Seventh Medical Center of PLA General Hospital from September 2010 to January 2022 were selected as the observation group, and the newborns without NLR, who were admitted to the Hospital at the same time and matched with gestational age and birth weight of the NLR newborns were selected as the control group at a ratio of 1∶2. The gestational age, birth weight, maternal complications, maximum leukocyte count, percentage of neutrophils, C-reactive protein, hemoglobin, platelet count, disease diagnosis and other relevant information of the newborns were recorded, and SPSS 21.0 statistical software was applied to compare the data of the two groups of newborns.Results:A total of 36 cases were in the observation group and 72 cases in the control group. Naive granulocytes were found in the peripheral blood of all patients in the observation group, and leukocyte count was higher than that of the control group [61.7 (54.2, 90.6)×10 9/L vs. 19.6 (14.2,27.3)×10 9/L], the difference was statistically significant ( P<0.001), but there was no statistically significant difference in the percentage of neutrophils, hemoglobin, platelets, and C-reactive protein between the two groups ( P>0.05). The proportion of vaginal delivery, meconium-stained amniotic fluid, and neonatal sepsis in the observation group were higher than that in the control group [69.4% (25/36) vs. 38.9% (28/72), 19.4% (7/36) vs. 5.6% (4/72), 47.2% (17/36) vs. 8.3% (6/72)], and the proportion of gestational diabetes mellitus, gestational hypertension and prenatal use of glucocorticoid was lower than that in the control group, with statistical significance ( P<0.05). There was no significant difference in the incidence of premature rupture of membranes, neonatal asphyxia, intracranial hemorrhage, pulmonary hemorrhage, bacterial meningitis, and bronchopulmonary dysplasia between the two groups ( P>0.05). Conclusions:Newborns with NLR are frequently complicated with sepsis. Early prevention and treatment of maternal comorbidities and active control of infection are important for the prevention and treatment of NLR.
