Abstract:
Objective To establish biological reference intervals of neonatal T lymphocyte subsets and IgG, IgA,IgMlevels in 24 -hour newborns in Guangxi.Methods Maternal history and neonatal clinical data were evalua-ted and recorded.Venous blood samplings were collected within 24 hours of birth and were sent for testing in half an hour.The neonates were divided into the early -preterm,the late -preterm and the term neonates group,1 1 0 cases for each group.The parturients were divided into Dexamethasone treatment group and without Dexamethasone treatment group.Data in neonates and the parturients and the sex were analyzed by SPSS 1 7.0 software and the biological refe-rence values were calculated.Results The two -sided reference intervals of 95% in the early -preterm group,the late -preterm group and the term neonates group were as follows:CD3 +:52.07 -88.92 g/L,58.1 6 -90.42 g/L, 56.1 5 -95.67 g/L;CD4 +:25.20 -59.26 g/L,31 .27 -72.91 g/L,28.44 -82.66 g/L;CD8 +:7.30 -36.26 g/L, 9.1 3 -38.49 g/L,1 1 .09 -48.99 g/L;CD4 +/CD8 +:0.34 -4.58,0.34 -4.58,0.32 -3.80;CD1 9 +:3.95 -27.59 g/L,4.04 -30.94 g/L,4.08 -38.70 g/L;NK cell:1 .34 -6.64 g/L,2.88 -8.92 g/L,3.07 -9.35 g/L;IgA:0.000 4 -0.039 6 g/L,0.000 0 -0.069 0 g/L,0.000 0 -0.069 0 g/L;IgM:0.001 6 -0.1 58 4 g/L,0.020 0 -0.1 40 0 g/L,0.020 0 -0.420 0 g/L;IgG:3.22 -1 0.98 g/L,1 .1 0 -1 4.62 g/L,5.00 -1 3.66 g/L.Moreover the ca-ses with Dexamethasone treatment were as follows:the late -preterm infants CD8 + 1 0.35 -40.33 g/L,NK 3.1 0 -9.46 g/L,term NK 6.60 -9.50 g/L;those in without Dexamethasone treatment:the late -preterm infants CD8 +8.42 -34.96 g/L,NK 2.94 -7.80 g/L,term NK 2.98 -8.94 g/L;according to gender,the males in the late -pre-term infants CD8 + 8.26 -35.66 g/L,term CD3 + 51 .90 -92.94 g/L;females in the late -preterm infants CD8 +1 1 .08 -40.68 g/L,term CD3 + 61 .1 0 -96.1 4 g/L.Conclusions Testing values of neonatal T lymphocyte subsets and IgG,IgA,IgM levels in 24 -hour newborns in Guangxi disperse largely and show some differences among the early -preterm neonates,the late -preterm neonates and the term neonates,and maternal Dexamethasone treatment during pregnancy and gender play a role in neonatal immunity.
