We investigated the metabolic profile, reactive species production, and inflammatory parameters in patients with epilepsy. Furthermore, we investigated whether there is any relationship between these parameters and seizure type. Patients with epilepsy (n=43) and healthy subjects (control group; n=41) were recruited to participate in the study. Initially, the participants were submitted to a clinical questionnaire and patients with epilepsy were classified according to seizure type. Metabolic markers and inflammatory and oxidative factors were also measured in specific blood samples. We compared these results with data from the control subjects. Statistical analyses showed that patients with epilepsy presented with higher levels of glycolipid, oxidative stress, and inflammatory parameters compared to the control subjects. Interestingly, patients with generalized seizures presented with higher MnSOD activity and metabolic parameters (total cholesterol, low-density lipoprotein, glucose and triglyceride levels) compared to the partial seizure and control groups. Furthermore, patients with generalized epilepsy demonstrated a significant correlation between TNF-α and caspase 8 (p<0.05), caspase 3 (p<0.05), and Picogreen (p<0.001). This study supports evidence that the levels of inflammatory, glycolipid, and oxidative factors are higher in epilepsy patients, especially those with generalized epilepsy.
