ABSTRACT |
Purpose: We studied to find out apo-E genotype polymorphism in minimal change nephrotic syndrome(MCNS) and IgA nephropathy(IgAN) and to determine the relationship between apo-E genotype and clinical course of MCNS. Materials and Method : 43 MCNS patients and 15 IgAN patients were examined for apo-E polymorphism. 50 healthy blood donors were examined for apo-E genotype as control. Genomic DNA was prepared front peripheral blood leukocytes according to standard procedures. Results : As compared with control group, e4 allele frequency was significantly increased in MCNS (p<0.01). However, in IgAN e2 allele frequency, however, was 2.6 times higher than normal control (P<0.01). The frequency of e4 allele of frequent relapser group was 4.6 times higher than normal control and was 2 times higher than infrequent relapser group. Conclusion : We think that apo-E typing might be one of the parameters, which should be considered to predict the course of MCNS in children. MCNS with risky HLA profile and E4/4 genotype could indicate the need for a longer steroid administration. And apo-E genotype needs to be considered for the evaluation of therapeutic responses to other drugs. (J, Korean Soc Pediatr Nephrol 2001 ; 5 : 87-99) |
