Abstract

Intracerebral hemorrhage (ICH) is a perplexing condition with high mortality and no treatment beyond supportive care. A major portion of the injurious process is takes place during the hours following the development of hematoma. This so-called secondary injury is characterized by an inflammatory cascade that involves a variety of cytokines, including tumor necrosis factor (TNF)-α. Several studies in the rodent model of ICH have shown a rapid increase in brain concentrations of TNF-α following hematoma induction. There is a reasonable body of evidence from experimental models of ICH suggesting that upregulation of TNF-α adjacent to the hematoma is associated with increased peri-hematomal edema, and that inhibition of TNF-α attenuates the formation and progression of this edema and ultimately improves outcomes. Unfortunately, efforts to expand upon these findings have interminably stalled at the pre-clinical phase. A robust clinical study to validate serum TNF-α as a marker for secondary injury in ICH patients is yet to materialize.
