Zusammenfassung
This study assessed if serum carnosinase (CN-1) activity, concentration and conformation in Type 2 diabetes mellitus (T2DM) patients carrying the protective CNDP1 genotype ((CTG)5 homozygous) with diabetic nephropathy (DN) differ from those without nephropathy. In a cross-sectional design 127 T2DM patients with DN and 145 T2DM patients without nephropathy were recruited. Additional control groups, i.e, non- diabetic controls (n = 111) and uraemic controls (n = 85) were included for assessing confounders. CNDP1 (CTG)5 homozygous T2DM patients with DN had significantly lower CN-1 concentrations (30.4 ± 18.3 vs. 51…
