Systemic redox biomarkers and their relationship to prognostic risk markers in autosomal dominant polycystic kidney disease and IgA nephropathy.

Patients with ADPKD and IGAN have evidence of oxidative stress from stage 1 to 4 - most pronounced in IGAN. In patients, aminothiol redox biomarkers were correlated to AOPP, proteinuria and PTH, which are known prognostic markers in CKD. It may be possible that oxidative stress influences PTH dysregulation in CKD. The association between IGAN and the redox related variant allele rs4880(C) might indicate a new susceptibility locus for IGAN, but this needs verification.
