这项竞争性延续提案的主要目标是:a)
首次获得下丘脑-垂体腺的连续测量结果-
老年人肾上腺(HPA)轴与交感神经系统(SNS)活动
大样本的心理创伤的人在直接
(B)创伤事件的后果和后续行动;要评估
HPA和SNS反应模式的时间进程与
发展创伤后应激障碍(PTSD);c.检视
创伤后应激障碍患者下丘脑室旁核与下丘脑室旁核之间可能的相互作用S
发病机制。
300名患者将在短期内获得HPA和SNS措施

英文摘要
The major objectives of this competing continuation proposal are: a.)to
obtain for the first time sequential measures of hypothalamic-pituitary-
adrenal (HPA) axis and sympathetic nervous system (SNS) activity in a
large sample of psychologically traumatized persons in the immediate
aftermath of the traumatic event and in follow-up; b.) to evaluate the
time course of HPA and SNS response patterns in relationship to the
development of post-traumatic stress disorder (PTSD); and c.) to examine
possible interactions between the SNS and HPA axis in PTSD s
pathogenesis.
HPA and SNS measures will be obtained in 300 patients shortly after
their presentation to the emergency room (ER) of a major urban teaching
hospital in Israel following an acute, psychologically traumatic event,
and at specified intervals during the next four months. HPA measures
will include a.) cortisol, adrenocorticotropin (ACTH), and lymphocyte
glucocorticoid receptor (GR) levels measured in saliva, blood, and/or
urine; b.) salivary cortisol peak-trough difference, area under the
curve, and rate of decline over the diurnal cycle; and c.) percentage
of cortisol and GR suppression induced by a 0.5 mg dose of the synthetic
steroid dexamethasone. SNS measures will include: a.) heart rate and
blood pressure; and b.) norepinephrine, epinephrine, and 3-methoxy-4-
hydroxy-phenylglycol (MHPG) levels measured in saliva, blood, and/or
urine.
Logistic regression will be used to predict PTSD vs. non-PTSD status at
four months. Predictor variables will be entered stepwise into the
analysis on a chronological basis, e.g., i.) past trauma history; ii.)
index traumatic event severity, iii.) response intensity to the index
traumatic event; iv.) ER HPA and SNS measures and their interactions;
and v.) post-ER HPA and SNS measures and their interactions. In this
way, evaluation of HPA and SNS predictor effects and interactions will
be adjusted for the effects of other relevant, antecedent variables, and
for earlier HPA axis and SNS effects and interactions.
