ABSTRACT
Objective To observe and analyze the difference of serum immunoglobulin IgA, IgG, IgM, β2-microglobulin and transferrin in pre-eclampsia (PE) and pregnancies complicated with chronic kidney disease.Methods Totally 46(40.0%)pregnancies with PE(PE group),36(31.3%)pregnancies with chronic kidney disease(chronic kidney disease group)and 33(28.7%)normal pregnancies with normal blood pressure and proteinuria without any complication(control group)delivered in Renji Hospital were recruicted in this study from February 2017 to July 2017.Serum IgA,IgG,IgM,β2-microglobulin and transferrin levels were detected. Correlation tests were conducted between these indicators and blood pressure, 24 hours proteinuria value and delivery weeks. Results (1) Comparison of general situation of pregnancies in the 3 groupsthere were no significant difference in the age and child bearing history between the 3 groups(all P>0.05),while there was a significant difference in the blood pressure and deliver week(all P<0.01).There was no significant difference in 24 hours proteinuria values between PE group and chronic kidney disease group (Z=-0.187, P=0.852). (2) Comparison of serum immunoglobulin, β2-microglobulin and transferrin levels in pregnant women with three groups serum IgA level in chronic kidney disease group was significantly higher than those in PE and control groups[(2.4±0.9)vs(1.8±0.9)vs(1.6±0.6)g/L;F=9.959,P<0.01].The serum IgG and IgM values had no significant difference between the 3 groups(all P>0.05).Serum β2-microglobulin in chronic kidney disease group was significantly higher than those in PE and control groups[(4.0±2.6)vs(2.7±0.7)vs(2.0±0.5)mg/L;F=15.892,P<0.01].Serum transferrin in chronic kidney disease group was significantly lower than those in PE and control groups[(3.0±0.8)vs(3.7±1.1)vs(3.6±0.6) g/L; F=6.284, P<0.01]. (3) The correlation between serum immunoglobulin, β2-microglobulin, transferrin and blood pressure, proteinuria value and delivery weeks in PE group the blood pressure level was not correlated with serum IgA,β2-microglobulin and transferrin values in PE group(all P>0.05).So,24 hours proteinuria value was positively correlated with β2-microglobulin (r=0.557, P<0.01), which was negatively correlated with transferrin (r=-0.442, P<0.01) and was not correlated with IgA(r=0.089, P=0.556). There was a negative correlation between delivery weeks and β2-microglobulin(r=-0.328,P=0.026),and positive correlation with transferrin (r=0.315, P=0.035) and no correlation with IgA (r=-0.169, P=0.260). (4) The correlation between serum immunoglobulin, β2-microglobulin, transferrin and blood pressure, proteinuria value and delivery weeks in chronic kidney disease groupthe blood pressure level was positively correlated with β2-microglobulin(systolic pressure r=0.598,P<0.01;diastolic pressurer=0.557,P<0.01),which was not correlated with IgA and transferrin in chronic kidney disease group (all P>0.05). So,24 hours proteinuria value was positively correlated with β2-microglobulin and IgA(r=0.568,r=0.330,both P<0.05), and not correlated with transferrin (r=0.255, P=0.133). Delivery weeks had a negative correlation with β2-microglobulin(r=-0.574,P<0.01),while it had a positive correlation with transferrin(r=0.369,P=0.027). No correlation was found between delivery weeks and IgA values (r=-0.257, P=0.131). Conclusion The serum levels of IgA,β2-microglobulin and transferrin in PE and pregnancies with chronic kidney disease are significantly different,which may provide clinical value for the diagnosis of PE and pregnancies with chronic kidney disease in future.
