    Although the link between chronic stress and the development of cardiovascular and metabolic diseases of adulthood has been known for some time, there is growing recognition that early environmental influences may result in developmental programming via epigenetic mechanisms, thereby affecting the developmental trajectory of disease progression. Previous studies support the idea that offspring of Holocaust survivors may have been subjected to early developmental programming. We evaluated the relationship between parental exposure to the Holocaust and selfreported health ratings and disorders made by their adult offspring (i.e., second generation Holocaust survivors). A total of 137 subjects were evaluated. Regression analyses demonstrated that maternal but not paternal exposure to the Holocaust was related to poorer subjective impressions of emotional and physical health. This relationship was diminished when the offspring’s own level of trait anxiety was considered. Offspring with maternal, but not paternal, Holocaust exposure also reported greater use of psychotropic and other medications, including medications for the treatment of hypertension and lipid disorders. The mechanism linking these health outcomes and maternal exposure deserves further investigation, including the possibility that fetal or early developmental programming is involved

    OBJECTIVE: In animal models, early life exposure to major environmental challenges such as malnutrition and stress results in persisting cardiometabolic, neuroendocrine and affective effects. While such effects have been associated with pathogenesis, the widespread occurrence of ‘developmental programming’ suggests it has adaptive function. Glucocorticoids may mediate ‘programming’ and their metabolism is known to be affected by early life events in rodents. To examine these relationships in humans, cortisol metabolism and cardiometabolic disease manifestations were examined in Holocaust survivors in relation to age at exposure and affective dysfunction, notably lifetime posttraumatic stress disorder (PTSD). METHODS: 51 Holocaust survivors and 22 controls without Axis I disorder collected 24-hr urine samples and were evaluated for psychiatric disorders and cardiometabolic diagnoses. Corticosteroids and their metabolites were assayed by gas chromatography mass spectroscopy (GCMS); cortisol was also measured by radioimmunoassay (RIA). RESULTS: Holocaust survivors showed reduced cortisol by RIA, and decreased levels of 5α-tetrahydrocortisol (5α-THF) and total glucocorticoid production by GCMS. The latter was associated with lower cortisol metabolism by 5α-reductase and 11ÎČ-hydroxysteroid dehydrogenase (11ÎČ-HSD) type-2. The greatest decrements were associated with earliest age of Holocaust exposure and less severe PTSD symptomatology. Cardiometabolic manifestations were associated with decreased 11ÎČ-HSD-2 activity. In contrast to the relationship in Holocaust survivors, in controls, 5α-reductase was positively associated with trauma-related symptoms. CONCLUSION: Extreme malnutrition and related stress during development is associated with long-lived alterations in specific pathways of glucocorticoid metabolism. These effects may be adaptive and link with lower risks of cardiometabolic and stress-related disorders in later life

    BACKGROUND: A proportion of subjects with symptoms of posttraumatic stress disorder (PTSD) are unresponsive to specialized psychotherapy, but a biological basis for this has not been described. To observe whether differences in cortisol or its metabolites predict or correlate with response to therapy for PTSD symptoms, cortisol and its metabolites were measured from urine samples at pre-treatment, at the conclusion of psychotherapy, and at 3-month follow-up. METHODS: 28 survivors of the World Trade Center attack on September 11, 2001 seeking psychological treatment for PTSD symptoms received four sessions of either exposure therapy or supportive counseling, followed by up to 10 sessions of prolonged exposure in a specialized PTSD treatment program at a private hospital serving the New York City metropolitan area. 24-hr mean integrated cortisol excretion was assessed by radioimmunoassay (RIA); urinary free cortisol and metabolites cortisone, 5α–tetrahydrocortisol (5α-THF), 5ÎČ–tetrahydrocortisol, and tetrahydrocortisone were assessed by gas chromatography-mass spectrometry (GCMS); and indices of enzyme activities for 5α–and 5ÎČ–reductase and for the 11ÎČ–hydroxysteroid dehydrogenases were derived from the metabolite and glucocorticoid measures. RESULTS: 5α-reductase activity was significantly lower at pre-treatment among non-responders, whereas there were no significant pre-treatment differences between responders and non-responders in any other hormone or metabolite level. In repeated-measures analyses across the three time points, 5α-reductase activity, as well as 5α-THF and total glucocorticoids, significantly differed between responders and non-responders. For urinary cortisol measured by RIA, there was a significant group × time interaction indicating that, although not different at pre-treatment, urinary cortisol levels declined over time in the non-responder group, such that by follow-up, lowered cortisol significantly distinguished non-responders from responders. Indices of 5α-reductase activity, including 5α-THF and total glucocorticoids, were significantly negatively correlated with avoidance symptom severity at pre-treatment. At follow-up, indices of 5α-reductase activity were significantly negatively correlated with severity of all three PTSD symptom clusters and with total PTSD severity scores. CONCLUSION: Lower 5α–reductase activity is associated with avoidance severity and predicts non-responsiveness to psychological treatment for PTSD symptomatology. Relatively diminished 5α–reductase activity may mark a state of primary vulnerability, perhaps via attenuated peripheral catabolism of cortisol resulting in the suppression of hypothalamic-pituitary-adrenal axis responsiveness. Lower cortisol levels appear later in the progression to chronic, treatment-resistant PTSD

    Glucocorticoid augmentation of prolonged exposure therapy: rationale and case report

    Get PDF
    Rationale: Prolonged exposure (PE) therapy has been found to reduce symptoms of posttraumatic stress disorder (PTSD); however, it is difficult for many patients to engage fully in the obligatory retelling of their traumatic experiences. This problem is compounded by the fact that habituation and cognitive restructuring – the main mechanisms through which PE is hypothesized to work – are not instantaneous processes, and often require several weeks before the distress associated with imaginal exposure abates. Case reports: Two cases are described that respectively illustrate the use of hydrocortisone and placebo, in combination with PE, for the treatment of combat-related PTSD. Based on known effects of glucocorticoids on learning and memory performance, we hypothesized that augmentation with hydrocortisone would improve the therapeutic effects of PE by hastening “new” learning and facilitating decreases in the emotional impact of fear memories during the course of treatment. The veteran receiving hydrocortisone augmentation of PE displayed an accelerated and ultimately greater decline in PTSD symptoms than the veteran receiving placebo. Conclusions: While no general conclusion can be derived from comparison of two patients, the findings are consistent with the rationale for augmentation. These case reports support the potential for an appropriately designed and powered clinical trial to examine the efficacy of glucocorticoids in augmenting the effects of psychotherapy for PTSD

    Background: Suicidal behavior is a critical problem among military veterans. Therefore, it is important to identify psychological suicide risk factors that are unique for veterans of military service. We compared clinical features of 55 veteran suicide attempters with 55 veterans without a history of suicide attempts. Methods: Demographic and clinical characteristics of suicide attempters and non-attempters were assessed and recorded. Based on the Scale for Suicide Ideation (SSI) all patients were divided into two groups: patients who do not report any suicidal ideation at all (non-ideators) and people who do (ideators). Results: There was no difference between the groups with regard to age (t= − 0.71, df = 108, p=0.48), gender (χ2=1.50, df = 1, p=0.36), and race (χ2=4.84, df = 5, p=0.44). There were more subjects with a lifetime history of bipolar disorder, substance dependence, or psychotic disorder among suicide attempters compared to non-attempters (χ2=6.67, df = 1, p=0.01, χ2=4.71, df = 1, p=0.04, and χ2=9.83, df = 1, p = 0.002, respectively). There were 34% of current suicide ideators among suicide attempters and 9.3% of suicide ideators among non-attempters (χ2=9.67, df = 1, p=0.002). There was no difference with regard to the proportion of patients with major depression or posttraumatic stress disorder between suicide attempters and non-attempters (χ2=0.10, df = 1, p=0.83 and χ2=0.41, df = 1, p=0.54, respectively). Conclusion: A history of suicide attempt in military veterans is associated with a lifetime history of bipolar disorder, substance dependence, psychotic disorder, or current suicidal ideation but not with a lifetime history of major depression or posttraumatic stress disorder

    Evidence for epigenetic alterations in PTSD

    No full text
    Rationale/statement of the problem : Neuropeptide Y (NPY) is a peptide with behaviorally relevant effects on the hippocampus and is thought to function as an endogenous anxiolytic. In prior work, we reported that veterans who had recovered from combat-related post-traumatic stress disorder (PTSD) had higher levels than those who were not combat exposed. NPY levels were significantly associated with the extent of symptom improvement, suggesting that plasma NPY levels may represent a biological correlate of resilience to, and/or recovery from, the adverse effects of trauma exposure. Cytosine methylation of the glucocorticoid gene (GR methylation) has been associated with PTSD risk and/or symptom expression. GR methylation is influenced by environmental factors that can result in enduring differences in function, including neuroendocrine regulation. As the NPY gene has glucocorticoid response elements, levels of circulating NPY represent a potential indicator of alterations in GR responsivity. Methods : The relationship of NPY to PTSD and GR methylation was examined in two samples. In the first sample, veterans who developed PTSD following combat exposure were compared to those who did not develop PTSD. In a second sample, veterans with combat-related PTSD were assessed prior to and following a course of prolonged exposure (PE). Results : In the cross-sectional study, veterans with PTSD had higher NPY levels than those who never developed PTSD (t (62) = − 1.99, p=0.05; 95.8±45.6 pm/l vs. 73.9±41.5 pm/l). NPY associated with number of GR methylated sites in the full sample (r=0.35, n=64, p=0.005), but not with average percent methylation (r= − 0.05). When the associations were examined separately by PTSD group status, results showed a positive association between NPY and number of methylated sites (r=0.36) as well as percent methylation (r=0.38) in veterans with PTSD. However, NPY was only associated with the number of methylated sites (r = 0.35) in the subjects who did not develop PTSD following combat exposure. In the treatment study, plasma NPY levels increased among veterans who responded to treatment (who no longer met diagnostic criteria for PTSD following PE), compared to treatment non-responders, as indicated by a significant group æ time interaction (F1,14 = 5.48, p=0.035). While plasma NPY was comparable in the two groups at pretreatment (responders: 71.4±20.3 pm/l, non-responders: 71.0±16.0 pm/l), responders had higher plasma NPY (84.0±24.2 pm/l) relative to non-responders (61.0±15.4 pm/l). Both pretreatment number of GR methylated sites (r=0.53, n=16, p=0.04) and average percent GR methylation (r=0.75, n=15, p=0.001) were associated with higher plasma NPY at post-treatment. Conclusion : To the extent that improvement from symptomatic PTSD may involve a mobilization of endogenous mechanisms to reduce hyperarousal and other post-trauma sequellae, the results of these studies are consistent in suggesting a role for NPY. NPY was elevated in a sample of combat veterans with PTSD, and increased in association with PTSD improvement in response to trauma-focused treatment. GR methylation was associated with combat-related PTSD in a cross-sectional study, and with treatment associated improvement in PTSD. These findings suggest that epigenetic modification of the GR gene may be associated with resilience in PTSD
