Genetic damage in chronic renal failure patients is associated with the glomerular filtration rate index.

Chronic renal failure (CRF) patients are considered to present genomic instability and, as a consequence, elevated levels of genetic damage. An open question is whether this damage is related to the stage of the pathology. To determine the background levels of genetic damage, a large population of 258 Caucasian adults (201 CRF patients and 57 controls) was analysed using the micronucleus (MN) assay.

Oxidative DNA damage in chronic renal failure patients.

Background: Chronic renal failure (CRF) patients present a high incidence of cardiovascular pathologies and cancer. This has been attributed to the existence of genomic instability in these patients, and consequently they should present elevated levels of genetic damage.

Methods: To determine the background levels of genetic damage and its specific levels of oxidative damage, a large population of 253 CRF patients (77 in dialysis) was analysed using the comet assay.
