Tumour necrosis factor alpha (TNF-alpha) is a proinflammatory cytokine. Stroke induces a rapid increase in TNF-alpha levels within and around the focus of damaged brain. The aim of our study was to evaluate, whether patients with stroke differ from control patients in the concentrations of TNF-alpha in cerebrospinal fluid and serum. We studied TNF-alpha levels in cerebrospinal fluid and serum in 30 patients with stroke within 24 h after onset of neurological signs and in 15 patients of control group with the diagnosis of tension headache and neurasthenia. In patients with stroke the levels of TNF-alpha in the cerebrospinal fluid and serum were significantly higher in comparison with control group. The results of our study may suggest the overproduction of TNF-alpha during first twenty-four hours of stroke.
