The Impact of the Oxidative Stress and Inflammatory Process on the Serum Levels of Malonaldialdehyde, Glutathione Peroxidase, and Interlukine-18 in Patients with Essential Hypertension

Abstract

Background and objectives: The oxidative stress, antioxidant status and inflammatory process are cooperative events involved in development and progression of essential hypertension. This study was as a step for elucidating the contribution of the malondialdehyde, glutathione peroxidase, interlukine -18 and lipid profile with the incidence, development, and progression of essential hypertension. Aims: The aims of this study were, to assess the change in serum malondialdehyde, glutathione peroxidase, interlukine-18 and lipid profile levels in patients with essential hypertension, moreover, find out the effect of other confounding factors age, gender and stage of the disease on the serum levels of focused parameters and finally detect the correlation between all interested parameters. Patients and Methods: This study was designed to examine the associations between the serum interested parameters levels with the incidence of essential hypertension in 50 patients of both genders, and for the comparing purpose an equal number of the matched age–gender healthy adults also enrolled in this study as a control group. The hypothesis that oxidant /antioxidant status and inflammatory process influence the risk of adverse clinical outcomes are worthy for investigating. Accordingly, malondialdehyde was measured using coloremetric method, while, glutathione peroxidase and interlukine -18 were measured using enzyme linked immmunosorbent assay and lipid profile was estimated using commercial kit. Results: Patients exhibited a significant elevation in the serum malondialdehyde, glutathione peroxidase, interleukin-18 and lipid profile levels as compared with the control group. Conclusion: The data of the present study indicated that an alteration in oxidant / antioxidant status and inflammatory process in patients with essential hypertension. This investigation provided the first evidence of the ability of malondialdehyde, glutathione peroxidase, interlukine -18 and lipid profile in combination patterns as a factors involved in essential hypertension pathophysiology, etiology and are regarded as a markers of prognostic significance and potential therapeutic targets for future. The demonstration of these parameters provided a new insights into understanding the independence of oxidative stress /antioxidant status and inflammatory pathways in essential hypertension incidence, development and progression.
