Nerve growth factor expression correlates with severity and outcome of traumatic brain injury in children.
Secondary brain damage after traumatic brain injury (TBI) involves neuro-inflammatory mechanisms, mainly dependent on the intracerebral production of cytokines. In particular, interleukin 1beta (IL-1beta) is associated with neuronal damage, while interleukin 6 (IL-6) exerts a neuroprotective role due to its ability to modulate neurotrophins biosynthesis. However, the relationship between these cytokines and neurotrophins with the severity and outcome of TBI remains still controversial. ⋯ NGF concentration in CSF is a useful marker of brain damage following severe TBI and its up-regulation, in the first 48 h after head injury together with lower IL-1beta expression, correlates with a favorable neurologic outcome. Clinical and prognostic information may also be obtained from IL-6 expression.
