Clinical Trial: Hormone Deficiency After Brain Injury During Combat
Study Status: Completed
Recruit Status: Unknown status
Study Type: Observational
Official Title: Prevalence of Hypopituitarism Following Combat-related Traumatic Brain Injury in a Military Population
Brief Summary: We would like to ascertain the prevalence of hypopituitarism after combat-related TBI. This will lead to enhanced awareness, recognition, and treatment of hypopituitarism, which can have life-saving ramifications and enhance quality of life and rehabilitation efforts in our combat veterans.
Detailed Summary: The prevalence of hypopituitarism after combat-related traumatic brain injury (TBI) is currently unknown. Recent civilian data on TBI show the prevalence of any pituitary hormone deficiency is as high as 80% after 12 months. While the military prevalence of hypopituitarism can be extrapolated from civilian data, a major limitation is the notably different mechanism of injury (i.e., blast) for military personnel compared to civilians (i.e., assaults, traffic accidents and falls). Little is known about the effect of shockwaves from a blast injury on central nervous system tissue, and due to the unique nature of blast-related TBI, the prevalence of pituitary dysfunction in affected service members may significantly differ from nonmilitary subjects in prior studies.
