Osteopontin Gene Polymorphism in Stroke Patients in Egypt

Status Not yet recruiting

Clinical Trial Summary

This study aims to investigate the correlation of serum osteopontin level as a predictior and a prognostic factor in upper egyptian patients and correlation between Osteopontin Gene Polymorphisms and serum level of osteopontin in ischaemic stroke patients

Clinical Trial Description

The Global Burden of Disease estimated that one person in four aged 25 years will have a stroke in the rest of her/his life. Among them, ischemic stroke (IS) represents 80%. Stroke is accompanied by a neuroinflammatory response involving immune system. These long-term processes following IS are still far from being understood. So, despite the significant improvement in the diagnosis and treatment of IS, the disability and mortality rate of IS are still rising. An assessment of the prognostic risk of IS should be carried out as early as possible and corresponding interventions should be adopted clinically, in order to have a significant impact on the prognosis of patients with IS. Predicting the outcome in individual patients solely based on clinical and radiological parameters is challenging for clinicians. Measuring blood biomarkers associated with inflammation, endothelial function, matrix remodeling, and immune functions, may improve prediction performance . Osteopontin (OPN) is a matricellular protein participating in many physiological and pathologic processes including wound healing, bone turnover, tumor genesis, inflammation, and immune responses . It is well accepted that OPN is an important mediator in stroke pathophysiology. OPN expression is upregulated in microglia surrounding the infarcted area and in microglia and infiltrating macrophages in the infarct area. OPN and microglia seems to exhibit an intimate relationship in stroke with rather beneficial functions for the clinical outcome. However, the role of OPN in stroke-related diseases as atherosclerosis and diabetes should be further disentangled as in this early phase of disease OPN may ultimately culminate in cerebrovascular dysfunction. OPN may exert opposing effects and should be therefore addressed differently. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
