Abstract

Drug-resistant epilepsy presents significant challenges in treating epileptic patients, leading to recurrent seizures and necessitating the use of polypharmacy with anti-epileptic drugs. Both of these conditions contribute to increased oxidative stress, which is detrimental to the brain. The aim of this study was to determine the role of vitamins C and E in reducing oxidative stress and seizure frequency in drug-resistant epileptic patients. This was a double-blinded, randomized clinical trial with a placebo, parallel design, and block randomization. The subjects were drug-resistant epileptic patients aged 1–18 years who received routine treatment. Randomization was performed on 100 patients who were divided into the treatment or placebo groups. The patients received a combination of vitamin C (100 mg/day) and vitamin E (200 IU/day for those <5 years or 400 IU/day for those ≥5 years) or a placebo for eight weeks. Malondialdehyde (MDA) levels and seizure frequency were measured prior to and after the intervention. A total of 42 and 46 patients were followed till the end of the study in the intervention and placebo groups, respectively. Our data indicated that the MDA levels prior to treatment were not significantly different between the treatment and placebo groups (0.901 vs 0.890 mmol/mL, p=0.920) and were significantly reduced after the treatment in both the treatment group (p<0.001) and placebo group (p=0.028). The changes in MDA levels (between post- and pre-treatment) were also not significantly different between the two groups (p=0.181). Our per-protocol analysis indicated that the reduction in seizure frequency was significantly higher in the treatment group compared to the placebo group (95% vs 35%, p<0.001), with 92% and 60% relative and absolute risk reduction, respectively. The intention-to-treat analysis also indicated that the reduction in seizure frequency was significantly higher in the intervention group than in the control group (80% vs 32%, p<0.001), with relative and absolute risk reduction of 70% and 48%, respectively. There was no significant relationship between changes in MDA levels and seizure frequency in either group. In conclusion, vitamins C and E could reduce seizure frequency and, therefore, could be considered as adjuvant therapy in drug-resistant epileptic patients.

Abstract

Ischemic stroke is a sudden onset of neurological deficit resulting from a blockage in cerebral blood vessels, which can lead to brain tissue damage, chronic disability, and increased risk of mortality. Secretome from hypoxic mesenchymal stem cells (SH-MSC) is a potential therapy to improve neurological deficit by increasing the expression of vascular endothelial growth factor (VEGF) and reducing glial fibrillary acidic protein (GFAP). These effects can reduce the infarction area of ischemic stroke. Therefore, the aim of this study was to analyze the effect of 150 μL and 300 μL SH-MSC injection on VEGF and GFAP expression as well as the improvement of infarction area in ischemic stroke animal model. A post-test-only experimental design with consecutive sampling was used, with Rattus norvegicus as subjects. Stromal mesenchymal stem cells (S-MSCs) were isolated from the umbilical cords of rats at 21 days of gestation. Secretome production by the S-MSCs was induced under a hypoxic condition, and subsequently isolated. The resultant secretome was administered to rats subjected to middle cerebral artery occlusion (MCAO) at doses of 150 μL (P1 group) and 300 μL (P2 group). The results showed that the infarction area was reduced in P1 (p<0.001) and P2 groups (p<0.001). SH-MSC at a dose of 300 μL increased the expression of VEGF (p=0.028) and reduced the expression of GFAP (p=0.001). In conclusion, secretome from hypoxic S-MSC could potentially improve ischemic stroke by upregulating VEGF expression and downregulating GFAP expression.
