Hypogonadism after traumatic brain injury

Abstract: Traumatic brain injury (TBI) is the most common cause of death and disability in young adults. Post-TBI neuroendocrine disorders have been increasingly acknowledged in recent years due to their potential contribution to morbidity and, probably, to mortality after trauma. Marked alterations of the hypothalamic-pituitary axis during the post-TBI acute and chronic phases have been reported. Prospective and longitudinal studies have shown that some abnormalities are transitory. On the other hand, there is a high f… Show more

“…Entre essas deficiências, o hipogonadismo é reconhecido hoje como frequente complicação secundária ao TCE, contribuindo para a alta morbidade observada nesses pacientes. Hohl et al, 16 analisando 30 pacientes, sendo 22 homens, com intervalo médio da avaliação laboratorial entre o TCE e o os exames laboratoriais, encontraram 10% dos pacientes (66,7% homens) com níveis de FSH abaixo do normal e 3,3% deles com nível baixo de LH. No grupo masculino, 9,1% apresentavam níveis de testosterona abaixo do valor de referência.…”

“…34 Much of the recently published literature established and confirmed the association of TBI with pituitary dysfunction. [38][39][40][41] Studies show that posttraumatic hypogonadism is common in the acute post-TBI phase, with most patients recovering within 1 year. However, in 10 to 17% of survivors, hypogonadism persists.…”

“…Described in 1918 ( 8 ), partial or complete hypopituitarism is a potential consequence of TBI ( 9 , 10 ). There are several mechanisms by which TBI can cause hypothalamus-pituitary dysfunction, including hypoxic insult or direct mechanical injury to the hypothalamus, pituitary stalk or the gland itself, compression from hemorrhage, edema or increased intracranial pressure, and vascular injury to the hypothalamus or the pituitary gland ( 10 13 ).…”
