title: [The role of polymorphic markers of vasoactive hormones genes in clinical characteristics of chronic glomerulonephritis].
abstract: OBJECTIVE
  To examine association of polymorphic markers of I/D gene of angiotensin-converting enzyme (ACE), C(-344)T gene of aldosterone synthetase (CYP11B2) and 4a/4b gene of endothelial synthetase of nitric oxide (NOS3) with clinical picture of chronic glomerulonephritis (CGN).
  
  
  METHODS
  The trial covered 167 CGN patients. Clinical characteristics of CGN (nephritis, debute, its clinical and morphological variants, analysis of the clinical course as regards arterial hypertension severity, rate of persistence of proteinuria (PU) of the nephrotic level for 6 months and longer, frequency of AH combination with persistent PU was made retrospectively in the groups of patients by genotypes of the genes ACE, CYP11B2 and NOS3.
  
  
  RESULTS
  In CGN patients, carriage of the combination of allele D of ACE gene, allele C of CYP11B2 gene, and allele 4a of NOS3 gene was associated with more frequently occurring nephrotic syndrome and AH in the disease onset. A CGN course in patients with genotype DD (ACE gene) often complicates with AH, in patients with genotype CC (gene CYP11B2) and in carriers of allele 4a (gene NOS3)--with severe AH. Carriers of allele D (gene ACE) HA often combines with persistent PU the nephrotic level. A morphological variant of CGN is not associated with carriage of genotypes of polymorphic markers of genes ACE, CYP11B2 and NOS3.
  
  
  CONCLUSIONS
  There is association of polymorphic markers I/D of ACE gene, C(-344)T of gene CYP11B2 and 4a/4b of gene NOS3 with clinical features of CGN. Carriers of alleles associated with high activity of PAAC--allele D of gene ACE, allele C of gene CYP11B2 and allele 4a of gene NOS3--had more severe clinical picture at all stages of the disease.
