Aim: The underlying pathophysiological mechanisms in epilepsy are still not fully known. Paraoxonase (PON)-1 activity and malondialdehyde (MDA) levels are biomarkers used in the measurement of oxidative stress. Studies show that oxidative stress has a role in the pathophysiology of epilepsy. The aim of our study is to evaluate serum PON-1 activity and MDA levels in epilepsy patients with and without status epilepticus (SE).
Materials and Method: The subjects included in the study were established in two groups. Group I: The patient diagnosed with status epilepticus (n=30), group II: 30 adult patients with epilepsy who were in the outpatient policlinic follow-up and were not in status were included in the study. Serum MDA levels and PON-1 activity were measured by spectrophotometric method in the biochemistry laboratory.
Results: Serum MDA levels were found to be 86.8±32.4 nmol/ mL in patients with SE and 65.8±15.7 nmol/mL in patients without SE. Serum PON-1 activity was 180.8±28.3 U/L in patients with SE and 170.2±25.0 U/L in patients without SE. When patients with SE and patients without SE were compared, serum MDA levels were found to be higher than patients without SE and statistically significant (p<0.001). There was no significant difference between the two patient groups in terms of PON-1 activity (p>0.05).
Conclusion: The results of our study indicate that the oxidant/ antioxidant balance in the pathogenesis of status epilepticus has deteriorated in favor of oxidative stress and the antioxidant system cannot give an adequate response. Larger research should be conducted to evaluate the use of serum MDA levels as a biomarker.
