The ACE D- and the ecNOS a-allele have been associated with an adverse prognosis in patients with glomerulonephritis (GN). Using genomic DNA we investigated by RT-PCR whether the two polymorphisms are useful prognostic markers in GN patients. In patients with primary GN (IgA-GN n = 70, membranous GN n = 23, FSGS n = 17, MPGN n = 6) neither the whole group nor disease-specific subgroups exhibited any alterations from the normal ACE genotype distribution. No significant associations were detected between the ACE genotype and the development of hypertension, antihypertensive therapy required, progression rate of the disease, age of diagnosis and the antiproteinuric response to ACE-inhibition. In 40 IgA-GN patients with ESRD no increased prevalence of the D-allele was noted. The distribution of the ecNOS-alleles in the above patients (a-allele 22%, b-allele 78%) was comparable to that of the normal controls. No association with any of the parameters mentioned above were detected in the case of the ecNOS-alleles.


In our Caucasian patients neither the determination of the ACE nor the ecNOS genotype offered any diagnostic or prognostic help.
