Summary: | Objective: To study the ACE2 gene polymorphism in children with primary nephrotic
syndrome (PNS) and its correlation with renal injury. Methods: A total of 47 children
diagnosed with PNS in our hospital between May 2013 and December 2015 were selected as
the PNS group of the study, they received prednisone therapy and the hormone sensitivity was
judged; 40 healthy children receiving physical examination in our hospital during the same
period were selected as the control group of the study. Peripheral blood was collected to extract
genomic DNA, and after PCR reaction and enzyme digestion reaction, ACE2 polymorphism
was judged; serum and renal biopsy tissue were collected to determine kidney function
indexes. Results: The constituent ratio of ACE2 gene GG genotype, AG genotype and AA
genotype as well as the constituent ratio of alleles G and A of PNS group were not significantly
different from those of control group while the constituent ratio of GG genotype and the
constituent ratio of allele G of children with steroid-resistant PNS were significantly higher
than those of children with steroid-sensitive PNS; Scr, BUN, UA and CysC content in serum
as well as TLR4, TLR7, NLRP3, Caspase-1, IL-1β and IL-18 expression levels in kidney
tissue of PNS children with GG genotype were significantly higher than those of PNS children
with AG genotype and AA genotype, and Scr, BUN, UA and CysC content in serum as well as
TLR4, TLR7, NLRP3, Caspase-1, IL-1β and IL-18 expression levels in kidney tissue of PNS
children with AG genotype were not significantly different from those of PNS children with
AA genotype. Conclusions: ACE2 gene polymorphism is associated with the steroid treatment
sensitivity in children with PNS, and children with GG genotype are with higher steroidresistant
risk, poorer renal function and higher expression of IL-1β and IL-18. |
