PTSD Prevention Using Oral Hydrocortisone

Preliminary findings using HCORT in PTSD prevention have been encouraging. However, it is imperative to provide a more definitive study of HCORT effects across a wide range of demographic and traumatic exposures. In addition, prior studies used a single IV dose of HCORT administered in the Emergency Department (ED) and it is critical to determine whether effects would be comparable using oral HCORT. The advantage of an oral prophylactic is that a pill is a portable prophylactic that could be carried by first responders, military personnel and other people whose occupations expose them to risk of trauma exposure. The results of this RCT will add to the existing literature in several important ways. The study will be larger in scope, and will target a more extensive biological profile to elucidate mechanisms of action. To maximize enrollment within a shorter period of time, the study will be conducted at two sites. The first site is the ED at the Mount Sinai Hospital, located in East Harlem in New York City (NYC), and the second is the ED at Sheba Medical Center in Israel. These sites allow for the evaluation of a broad range of trauma survivors. In NYC, the large urban ED provides services to a diverse population with respect to race, ethnicity and trauma exposure. At Sheba Medical Center, those who present to the ED are active duty, reserve military personnel and civilians. By including both sites, the investigators will be able to evaluate the effectiveness of the intervention in a global and more ethnically diverse sample that includes people exposed to a wide variety of traumas. Prior research and results from the researchers' intervention studies indicate the importance of recruiting participants who are distressed, including those expressing feelings of dissociation, when they present to the ED (i.e., such people are at greater risk for the development of PTSD) following trauma exposure that is life-threatening or causes injury. For this reason, the current study will select participants who meet a specified threshold for acute distress following trauma exposure. There is accumulating evidence to support the potential mechanism of action of the administration of HCORT on achieving homeostasis and resilience following exposure to a critical traumatic incident. In this interventional study, the researchers will collect blood samples for the purpose of conducting further analyses of biomarkers to obtain more information about the mechanisms of action of this intervention and to enhance knowledge about mechanisms associated with resilience. These aims will be achieved by assessing candidate neuroendocrine biomarkers as well as related molecular networks (e.g., genome wide methylation and expression) relevant to PTSD risk, and resilience. If the current trial using oral administration of HCORT is successful, it will generate a viable, safe, portable, lightweight, prophylactic treatment that can be self-administered and made available to military personnel, first responders and other civilians exposed to extreme trauma.
