State of acute phase markers and oxidative stress in patients with kidney stones in the urinary tract - Abstract

OBJECTIVE:This present study has aimed to assess the state of acute phase markers and oxidative stress in patients with kidney stones.

MATERIAL AND METHODS: A prospective study was carried out on 100 patients with kidney stones and 25 healthy controls. Albumin, ß2 microglobulin, Gamma-glutamyl transpepsidase, Lactate dehydrogenase, Tumor necrosis factor alpha, Interleukin 1 and Interleukin-6 were evaluated as acute phase markers and lipid peroxidation products, Superoxide dismutase and Glutathione peroxidase levels acted as oxidative stress markers.

RESULTS: An increase in renal cell damage markers as expressed by the ß2 microglobulin (p=0.04), albumin (p=0.004), Lactate dehydrogenase (p=0.001) and Gamma glutamyl transpepsidasa (p=0.01) was observed in the patient group. There was a direct correlation between levels of ß2microglobulin and stone size (r=0.3, p=0.03). The association between stone size and cytokine activation was observed to be stronger in patients with staghorn calculi. In these patients, Tumor necrosis factor alpha (p=0.011), Interleukin 1 (p=0.004) and Interleukin 6 (p=0.004) were significantly higher. Patients with stones in the urinary tract showed data of significantly higher oxidative stress, expressed as an increase in levels of lipid peroxidation products (p=0.03) and a decrease in the antioxidant activity of Superoxide dismutase (p=0.03) and Glutathione peroxidase (p=0.002).

CONCLUSIONS: Patients undergoing urolithiasis showed an elevation of acute phase markers, associated with oxidative stress as expressed by an increase in lipid peroxidation products and a decrease in the antioxidant enzyme activity.
