Design and methods: Nineteen patients with ARE and twenty healthy children, age- and sex-matched were included in the study. Follow-up studies were made at the 7(th), 14(th), 21(st) and 28(th) day of diagnosis. Results: Children with ARF had significantly higher serum homocysteine levels and lower TAC than the same parameters of the controls at all measurements. Following the anti-inflammatory therapy, we found a progressive increase in TAC and a decrease in homocysteine levels of the patients. Conclusion: We concluded that increased serum homocysteine levels and decreased serum TAC of the patients with ARF can be considered as a sign of increased inflammation and oxidative stress in these patients which needs to be considered during therapy. Further studies are needed to understand the underlying mechanisms of these findings. (c) 2007 The Canadian Society of Clinical Chemists. Published by Elsevier Inc.
