An evaluation of neuroendocrine dysfunction following acute aneurysmal subarachnoid hemorrhage: A prospective study

Objective: The aim was to investigate the incidence and pattern of neuroendocrine changes in cases of acute aneurysmal subarachnoid hemorrhage (SAH). Materials and Methods: Endocrine assessment was performed in 100 consecutive cases of acute aneurysmal SAH presenting within 7 days of ictus. The gonadotropic, somatotrophic, thyrotropic, and corticotrophic axes were evaluated for their possible dysfunction. Results: A total of 100 cases (38 males, 62 females; age range - 17-76 years; mean age - 43.6 years) of acute SAH were studied. The aneurysms were located in the anterior circulation (n = 95) and posterior circulation (n = 5). The most common hormone deficiency was of growth hormone (n = 67), followed by gonadotrophin (n = 50), corticotrophin (n = 49) and thyrotrophin (n = 35). Hyperprolactinemia was noted in 10 cases. One-pituitary hormone axis deficiency was noted in 26 cases while 67 cases had two or more pituitary hormone axes dysfunction. A total of 93 cases had hormonal dysfunction in one or more pituitary hormone axes, and seven cases had no hormonal dysfunction. Conclusions: Endocrine dysfunction occurs in 93% cases of acute SAH and multiple pituitary hormone axes dysfunction occurs in 67% cases. It is suggested that hormonal evaluation should be considered as part of management of acute SAH.
