METHODS Our trauma and control groups included 11 consecutive patients with isolated SHI and 9 patients with hydrocephalus (one with normotensive and eight with hydrocephalus due to aqueduct stenosis), respectively. Both serum and cerebrospinal fluid levels of IGF-1 and IGFBP-3 were measured during post-traumatic days and we compared the levels with controls. RESULTS Patients and controls showed undetectable levels of both IGF-1 and IGFBP-3 in their CSF. When considering serum levels, patients with SHI had always lower levels of both molecules than that of controls. CONCLUSION Administration of IGF-1 during acute, as well as chronic phase of severe head trauma may provide beneficial effects and may decrease both mortality and morbidity in humans with SHI.eninfo:eu-repo/semantics/closedAccessbrain trauma/drug therapyIGF-1IGFBP-3immunohistochemistry/methodsneuroprotectionsevere head injuryArticle134281287N/A
