Correlation between Platelet Activating Factor Acetylhydrolase and Primary Nephrotic Syndrome / 实用儿科临床杂志

ABSTRACT

Objective To investigate the association of platelet activating factor acetylhydrolase(PAF-AH) activity in children with primary nephrotic syndrome(PNS).Methods The plasma PAF-AH activity was measured in 78 children with PNS who were divided into 3 groups:steroid-responsive nephritic,steroid-dependent nephritic,steroid-resistent nephritic,after they had been given steroid for 6 months.The plasma PAF-AH activity were also measured in 60 healthy children at the same age,with spectrophotometric assay,at the ame time,the blood cholesterol was measured.Results The blood cholesterol has positive correlation with the plasma PAF-AH activity,there was no significant difference of the blood cholesterol among 3 groups in nephrotic syndrome children,there was a significant difference in the plasma PAF-AH activity among 3 groups in PNS children,but there was no significant difference in the plasma PAF-AH activity between the groups of steroid-responsive nephritic and healthy children.Conclusion Plasma PAF-AH activity is related to the sensibility to steroid treatment in children′s PNS,and the plasma PAF-AH activity in steroid-resistent nephritic is higher than steroid-dependent nephritic.It is a question that if gene mutation is related with PAF-AH activity.
