Oxidative Stress and C-Reactive Protein in Patients with Cerebrovascular Accident (Ischaemic Stroke): The role of Ginkgo biloba extract.

OBJECTIVES
This study aimed to investigate the presence of oxidative stress and inflammation in ischaemic stroke patients by measuring malondialdehyde (MDA), total antioxidant status (TAS), and highly-sensitivity C-reactive protein (hsCRP) in the early post-ischaemic period, and to determine the role of Ginkgo biloba therapy in correcting the markers of oxidative stress and inflammation.


METHODS
This study was conducted at Ibn Seena Hospital, Mosul City, Iraq and included 31 cerebrovascular accident (CVA) patients and 30 healthy controls. Ischaemic stroke patients were divided into two groups: group I (n = 15) received conventional therapy; group II (n = 16) received conventional therapy with G. biloba (1500 mg/day) for 30 days. Blood samples were obtained from patients and controls before treatment and assays done of serum levels of MDA, TAS, and hsCRP. For CVA patients, a post-treatment blood sample was taken and the same parameters reassessed.


RESULTS
Compared with the controls, patients' serum levels of MDA, and hsCRP were significantly higher (P ≤0.001) and TAS significantly lower. Group I and II patients reported a significant reduction in serum levels of MDA and hsCRP and a significant increase in serum levels of TAS, in comparison with pre-treatment levels. There was no significant difference (P = 0.19) in serum MDA levels between groups I and II, whereas, serum TAS levels were significantly higher (P ≤0.01) and hsCRP significantly lower (P ≤0.01) in group II.


CONCLUSION
Acute stroke is associated with oxidative stress and inflammatory response in the early period. G. biloba plays a potential role in reducing oxidative damage and inflammatory response.
