Comparative StudyOxidative stress is increased in critically ill patients with acute renal failure.
Patients with acute renal failure (ARF) experience a high mortality rate. Dysregulated inflammation and altered metabolism may increase oxidative stress in ARF patients. Thirty-eight patients who met the Program to Improve Care in Acute Renal Disease (PICARD) Study inclusion criteria underwent plasma protein oxidation and plasma cytokine measurements. ⋯ Plasma proinflammatory cytokine levels were significantly higher (P < 0.05) in ARF patients and critically ill patients than in healthy subjects. Plasma protein oxidation is markedly increased in ARF patients compared with healthy subjects, ESRD patients, and critically ill patients. Increased oxidative stress may be an important target for nutritional and pharmacologic therapy in ARF patients.
