Relationship between posttraumatic stress disorder characteristics of Holocaust survivors and their adult offspring.

OBJECTIVE: There is controversy regarding the long-lasting effects of the Holocaust on the adult children of Holocaust survivors. In the present study the authors examined the relationship between posttraumatic stress disorder (PTSD) characteristics of Holocaust survivors and their adult children to determine whether differences in symptom severity or diagnostic status of parents would be associated with similar characteristics in their adult children. METHOD: Holocaust survivors (N = 22) and their offspring (N = 22) were interviewed with several instruments to assess lifetime trauma history, effect of trauma on one's life, level of intrusive and avoidance symptoms in response to reminders of the Holocaust, current and lifetime PTSD, and current and lifetime axis I psychiatric disorder other than PTSD. RESULTS: There were significant relationships between parents and children regarding the effect of trauma on one's life and level of intrusive, but not avoidance, symptoms in response to reminders of the Holocaust. Offspring with traumatic events were more likely to develop PTSD if their parents had PTSD. CONCLUSIONS: Symptoms in offspring may be related to presence and severity of symptoms in the parent. Furthermore, PTSD in the parent may be a risk factor for PTSD in offspring.

Alexithymia in Holocaust survivors with and without PTSD.

Alexithymia was measured in non-treatment seeking, community-dwelling Holocaust survivors using the Toronto Alexithymia Scale-Twenty Item Version (TAS-20). Scores of survivors with (n = 30) and without (n = 26) posttraumatic stress disorder (PTSD) were compared, and associations among alexithymia, severity of trauma, and severity of PTSD symptoms were determined. Survivors with PTSD had significantly higher scores on the TAS-20 compared to survivors without PTSD. TAS-20 scores were significantly associated with severity of PTSD symptoms, but not with severity of trauma. This study adds to our knowledge of the relationship between alexithymia and trauma by demonstrating that this characteristic is related to the presence of posttraumatic symptoms and not simply exposure to trauma.

Microextraction of volatile organic compounds using the inside needle capillary adsorption trap (INCAT) device.

A novel method of solventless extraction has been developed based on a combination of solid phase micro extraction and purge and trap methods. In this technique, a hollow needle with either a short length of GC capillary column placed inside it, or an internal coating of carbon, is used as the preconcentration device. Sampling may be performed on ambient air, on solution, or the solution headspace, by passing the gas or liquid through the device either actively with a syringe, or passively via diffusion. The VOC are sorbed and concentrated onto either the carbon layer, or the liquid stationary phase of the capillary column, within the needle. Placing the needle into a heated GC injection port thermally desorbs the organic compounds directly into the GC without the need for solvent extraction. Results suggest that this procedure provides a rapid and sensitive alternative method to those currently available.

Prolactin response to low-dose dexamethasone challenge in combat-exposed veterans with and without posttraumatic stress disorder and normal controls.

The prolactin and cortisol responses to dexamethasone (0.5 mg) were studied in combat veterans with (n = 18) and without (n = 12) posttraumatic stress disorder (PTSD) and normal controls (n = 18). Both veteran groups demonstrated greater prolactin suppression than the normals. In contrast, only veterans with PTSD showed an enhanced cortisol suppression in response to dexamethasone. These findings suggest that the prolactin response to dexamethasone may reflect a feature of combat exposure rather than PTSD per se.

Dissociation in aging Holocaust survivors.

OBJECTIVE: This study explored relationships among dissociation, trauma, and posttraumatic stress disorder (PTSD) in elderly Holocaust survivors with and without PTSD and in a demographically comparable group of nontraumatized subjects. METHOD: Holocaust survivors with PTSD (N = 35) and without PTSD (N = 25) who had been recruited from the community and a comparison group (N = 16) were studied. Dissociation was evaluated with the Dissociative Experiences Scale. Past cumulative trauma and recent stress were evaluated with the Antonovsky Life Crises Scale and the Elderly Care Research Center Recent Life Events Scale, respectively. PTSD symptoms were assessed with the Clinician-Administered PTSD Scale. RESULTS: The Holocaust survivors with PTSD showed significantly higher levels of current dissociative experiences than did the other groups. However, the extent of dissociation was substantially less than that which has been observed in other trauma survivors with PTSD. Dissociative Experiences Scale scores were significantly associated with PTSD symptom severity, but the relation between Dissociative Experiences Scale scores and exposure to trauma was not significant. CONCLUSIONS: Possible explanations for this finding include the age of the survivors, the length of time since the traumatic event, and possible unique features of the Holocaust survivor population. Nevertheless, the findings call into question the current notion that PTSD and dissociative experiences represent the same phenomenon. The findings suggest that the relationships among dissociation, trauma, and PTSD can be further clarified by longitudinal studies of trauma survivors.

Impact of cumulative lifetime trauma and recent stress on current posttraumatic stress disorder symptoms in holocaust survivors.

OBJECTIVE: The purpose of this study was to examine the relationships among cumulative lifetime trauma, recent stressful events, and presence and severity of current posttraumatic stress disorder (PTSD) symptoms in Holocaust survivors and nonexposed comparison subjects. METHOD: Lifetime trauma, recent stressful events, and presence and severity of PTSD were assessed in Holocaust survivors (N=72) and comparison subjects ( N=19). RESULTS: Survivors with PTSD (N =40) reported significantly greater cumulative trauma and recent stress than survivors without PTSD (N=32) and comparison subjects. Severity of PTSD symptoms, cumulative trauma, and recent stress were significantly associated. CONCLUSIONS: The presence and severity of current PTSD were related to having experienced stressful events in addition to the Holocaust.

Low urinary cortisol excretion in Holocaust survivors with posttraumatic stress disorder.

OBJECTIVE: The authors' objective was to compare the urinary cortisol excretion of Holocaust survivors with posttraumatic stress disorder (PTSD) (N = 22) to that of Holocaust survivors without PTSD (N = 25) and comparison subjects not exposed to the Holocaust (N = 15). METHOD: Twenty-four-hour urine samples were collected, and the following day, subjects were evaluated for the presence and severity of past and current PTSD and other psychiatric conditions. RESULTS: Holocaust survivors with PTSD showed significantly lower mean 24-hour urinary cortisol excretion than the two groups of subjects without PTSD. Multiple correlation analysis revealed a significant relationship between cortisol levels and severity of PTSD that was due to a substantial association with scores on the avoidance subscale. CONCLUSIONS: The present findings replicate the authors' previous observation of low urinary cortisol excretion in combat veterans with PTSD and extend these findings to a non-treatment-seeking civilian group. The results also demonstrate that low cortisol levels are associated with PTSD symptoms of a clinically significant nature, rather than occurring as a result of exposure to trauma per se, and that low cortisol levels may persist for decades following exposure to trauma among individuals with chronic PTSD.

Dose-response changes in plasma cortisol and lymphocyte glucocorticoid receptors following dexamethasone administration in combat veterans with and without posttraumatic stress disorder.

BACKGROUND: Our previous studies have suggested that combat veterans with posttraumatic stress disorder (PTSD) have alterations in hypothalamic-pituitary-adrenal axis functioning that are different from the well-documented biological changes observed in major depressive disorder and following exposure to stress. METHODS: In the present study, we examined cortisol and lymphocyte glucocorticoid receptor number before and after the administration of 0.50 and 0.25 mg of dexamethasone in 14 combat veterans with PTSD, 12 combat veterans without PTSD, and 14 nonpsychiatric healthy men. All subjects were medication free at the time of testing and none met diagnostic criteria for major depression or substance dependence. RESULTS: Combat veterans with PTSD suppressed cortisol to a greater extent than did combat veterans without PTSD and normal controls in response to both doses of dexamethasone. Differences in cortisol suppression could not be attributed to substance dependence history or differences in dexamethasone bioavailability. Combat veterans with PTSD showed a larger number of baseline glucocorticoid receptors compared with normal men. Combat veterans without PTSD also had a larger number of baseline glucocorticoid receptors compared with normal men and in fact were comparable to combat veterans with PTSD on this measure. However, only veterans with PTSD showed a decrease in lymphocyte glucocorticoid receptor number following dexamethasone administration. CONCLUSION: The data support the hypothesis of an enhanced negative feedback sensitivity of the hypothalamic-pituitary-adrenal axis in PTSD.

Psychological dimensions of depression in borderline personality disorder.

OBJECTIVE: The authors' goal was to test empirically a commonly held assumption that the depression in borderline personality disorder is primarily anaclitic. METHOD: The Depressive Experiences Questionnaire and the Hamilton Rating Scale for Depression were administered to 26 patients with borderline personality disorder (16 of whom were depressed) and 12 depressed patients without borderline personality disorder. RESULTS: Patients with borderline personality disorder showed more self-criticism but did not endorse more anaclitic items than depressed patients without borderline personality disorder. CONCLUSIONS: These findings suggest that self-criticism is an underemphasized characteristic of depression in borderline personality disorder.

Depressive features in Holocaust survivors with post-traumatic stress disorder.

The present study was designed to explore several aspects of depressive phenomenology, including current symptoms, dependency (anaclitic) and self-criticism (introjective) themes, and issues of self-efficacy, in Holocaust survivors with and without posttraumatic stress disorder (PTSD). The Depressive Subscale of the Symptom Checklist-90 (SCL-90) and the Depressive Experiences Questionnaire (DEQ) were administered to 23 Holocaust survivors and 18 demographically-matched controls. Holocaust survivors with PTSD scored significantly higher on the SCL-90 depression scale, and portrayed more self-criticism on the DEQ, than Holocaust survivors without PTSD and demographically-matched non-exposed subjects. The data suggest that depressive symptoms in individuals who have been severely traumatized are more severe when associated with a concurrent PTSD. Furthermore, groups suffering different types of trauma may show similarities in psychological dimensions of depression.

Glucocorticoid receptor number and cortisol excretion in mood, anxiety, and psychotic disorders.

In the present study, we measured cytosolic lymphocyte glucocorticoid receptor and 24-hour urinary cortisol excretion in patients with major depressive disorder, bipolar mania, posttraumatic stress disorder, panic disorder, and schizophrenia. Patients with major depression had the smallest, and posttraumatic stress disordered patients the largest, mean number of glucocorticoid receptors per cell compared to patients in the other groups. Bipolar manic and panic patients did not differ from each other in regard to the number of lymphocyte glucocorticoid receptors. Bipolar manic and panic patients did have significantly more glucocorticoid receptors/cell than schizophrenic patients. The mean 24-hour urinary cortisol excretion was significantly higher in patients with major depression and bipolar mania than in those in the other diagnostic groups. Lymphocyte glucocorticoid receptor number and cortisol excretion tended to be inversely related, when the entire sample was considered as a whole, but this effect did not reach statistical significance. It is concluded that lymphocyte glucocorticoid receptors may be modulated by multiple influences, not just ambient cortisol levels. These preliminary data suggest that the assessment of lymphocyte glucocorticoid receptor number in tandem with cortisol levels may provide a more meaningful estimate of hypothalamic-pituitary-adrenal axis activity than is achieved using cortisol alone.

Personality disorders in treatment-seeking combat veterans with posttraumatic stress disorder.

OBJECTIVE: Many patients with posttraumatic stress disorder (PTSD) appear to have co-occurring symptoms of character pathology; however, to date there have been no empirical studies of comorbid clinician-rated axis II personality disorders in war veterans with chronic PTSD. The authors' objective was to assess DSM-III-R personality disorders in treatment-seeking combat veterans with PTSD. METHOD: They used the Personality Disorder Examination, a standardized diagnostic interview for DSM-III-R axis II disorders, to assess DSM-III-R personality disorders in 34 patients with PTSD; 18 of the subjects were inpatients and 16 were outpatients. RESULTS: A high rate of character pathology was observed in both inpatient and outpatient groups. The most frequent disorders for which criteria were met were borderline, obsessive-compulsive, avoidant, and paranoid personality disorders. Inpatients had a higher rate of nearly every personality disorder than did outpatients. Inpatients were significantly more likely to meet diagnostic criteria for paranoid, schizotypal, avoidant, and self-defeating personality disorders. CONCLUSIONS: War-related PTSD in treatment-seeking Vietnam veterans is often accompanied by diffuse, debilitating, and enduring impairments in character. Subtyping patients with PTSD on the basis of specific axis II profiles may aid in the selection of more specific and effective treatments.

Psychoneuroendocrine assessment of posttraumatic stress disorder: current progress and new directions.

1. Studies in our laboratory have used the psychoendocrine strategy to explore differences in basal hormone levels between patients with posttraumatic stress disorder (PTSD) and other groups. This approach has allowed us to explore the relationship between hormone levels and specific psychological and biological processes which appear to develop following exposure to extreme trauma. 2. The concurrent assessment of several hormonal systems provides an opportunity to explore differences in hormonal patterns in various psychiatric disorders. PTSD appears to be characterized by a specific profile of hormonal changes that is distinct from that of other diagnostic groups and normal controls. These findings raise the possibility that the psychoendocrine approach may be useful in further exploring the pathophysiology and diagnosis of PTSD. 3. This paper reviews psychoendocrine changes in PTSD and describes updated multivariate methods that further elucidate psychological and neurochemical correlates of hormonal alterations in this disorder.

Long-lasting hormonal alterations to extreme stress in humans: normative or maladaptive?

The biological consequences of stress have been studied for over half a decade, however, little is known about persistent biological alterations after extreme stress in humans. Posttraumatic stress disorder (PTSD) is a syndrome that occurs in some individuals after exposure to extreme stress. In this review, we summarize some of our studies of hypothalamic-pituitary-adrenal axis alterations in PTSD and compare and contrast these findings with knowledge concerning biological changes following stress.

Urinary catecholamine excretion and severity of PTSD symptoms in Vietnam combat veterans.

In the present study, we replicated and extended our previous findings of increased 24-hour urinary catecholamine excretion in posttraumatic stress disorder (PTSD). Dopamine, norepinephrine, and epinephrine concentrations were measured in 22 male patients with PTSD (14 inpatients and eight outpatients) and in 16 nonpsychiatric normal males. The PTSD inpatients showed significantly higher excretion of all three catecholamines compared with both outpatients with PTSD and normal controls. Dopamine and norepinephrine, but not epinephrine, levels were significantly correlated with severity of PTSD symptoms in the PTSD group as a whole. In particular, these catecholamines seemed related to intrusive symptoms. None of the catecholamines were correlated with severity of depression. The findings support the hypothesis of an enhanced sympathetic nervous system activation in PTSD, and suggest that increased sympathetic arousal may be closely linked to severity of certain PTSD symptom clusters.

Exposure to atrocities and severity of chronic posttraumatic stress disorder in Vietnam combat veterans.

OBJECTIVE: The authors' objective was to explore aspects of trauma associated with severity of posttraumatic stress disorder (PTSD) in Vietnam veterans. METHOD: Several ratings of stress exposure and symptom severity were administered to 40 patients with combat-related PTSD. RESULTS: A significant relationship was observed between exposure to atrocities and the impact of PTSD on veterans' lives, as measured by the Mississippi Scale for Combat-Related Posttraumatic Stress Disorder. Exposure to atrocities was also significantly correlated with current symptom severity. In contrast, combat exposure alone was not significantly associated with overall symptom severity. Both atrocity and combat exposure, however, were significantly related to reexperiencing symptoms. CONCLUSIONS: The data suggest that the enduring effect and severity of PTSD symptoms on an individual are associated more with exposure to brutal human death and suffering than the threat of death associated with combat.

Neuroendocrine responses in alcoholics to the presentation and consumption of a perceived alcoholic beverage.

Eight male alcoholic inpatients in their 2nd week of treatment were presented with, and instructed to consume, a beverage described at one session as containing alcohol and at another as not containing alcohol. The beverage on each occasion did not, in fact, contain alcohol. The results indicated that when subjects believed they had consumed alcohol, the change in insulin from baseline was significantly greater at 10, 20, and 30 min following consumption. The findings suggest that the insulin response of alcoholics following ingestion of a carbohydrate-containing beverage is enhanced by the anticipation of ethanol.

Hypothalamic-pituitary-adrenal dysfunction in posttraumatic stress disorder.

Neuroendocrine studies examining the hypothalamic-pituitary-adrenal (HPA) axis under baseline conditions and in response to neuroendocrine challenges have supported the hypothesis of altered HPA functioning in posttraumatic stress disorder (PTSD). However, to date, there is much debate concerning the nature of HPA changes in PTSD. Furthermore, in studies showing parallel findings in PTSD and major depressive disorder there is controversy regarding whether the HPA alterations suggest a specific pathophysiology of PTSD, or, rather, reflect comorbid major depressive disorder. This review summarizes findings of HPA axis dysfunction in both PTSD and major depressive disorder, and shows distinct patterns of HPA changes, which are probably due to different mechanisms of action for cortisol and its regulatory factors.
