The lack of a rapid and clinically accurate diagnostic tool remains a major obstacle to optimal care of patients with stroke. Cytokine changes in patients with acute stroke have been insufficiently studied. The purpose of this study is to delineate the relevance of IL-6 as a biochemical marker of stroke diagnosis, taking into account the genetic basis, and changes of the protein in serum and cerebrospinal fluid in relation to stroke development. inflammation has an important role in ischemic cerebrovascular disease pathophysiology. Proinflammatory cytokines, such as IL-6, have been implicated in several mechanisms that might promote ischemic brain injury and an early neurological worsening. Cardiovascular diseases constitute one of the principal health problems in developing countries. Over the past few years, several studies have found evidence of the important role of inflammation in the ischemic cerebrovascular disease. The availability of a diagnostic biomarker panel for patients with stroke symptoms would be enormously valuable to complement clinical data and to precede radiological findings. IL-6 levels in cerebrospinal fluid and serum seem to reflect either the extent of tissue damage, or the accompanying clinical worsening. The -174 G/C functional polymorphism in the IL-6 gene might not be solely involved in disease susceptibility but also in linkage disequilibrium with other functional polymorphisms. Further studies are needed to solve this. Presently, the association between IL-6 genotype and stroke remains undetermined. Development of new neuroprotective therapies targeted to modulate cytokine-incluced inflammation could be a promising way to prevent early deterioration in acute ischemic stroke.
