OBJECTIVE - Evidence supports high rates of co-occurrence of posttraumatic stress disorder (PTSD) and chronic pain disorders involving central sensitization (CS). The nature of this relationship, however, remains relatively unexplored. In this study, we aimed to (1) assess how both trauma exposure and current PTSD symptoms are related to clinical manifestations of CS, and (2) test whether PTSD symptoms explain the relationship between trauma exposure and CS. Because experiential avoidance has been shown to impact the relationship between trauma and health outcomes, we (3) explored experiential avoidance as a possible mediator or moderator of the trauma-CS relationship.
METHODS - A sample of 202 adult patients (79% female) with chronic pain completed validated self-report measures of trauma exposure, current PTSD symptoms, experiential avoidance, and 3 manifestations of CS: widespread pain, greater pain severity, and polysomatic symptom reporting. We used path analysis and multivariate regression to assess our study aims.
RESULTS - Both trauma exposure and PTSD symptoms were significantly associated with all 3 clinical indicators of CS. PTSD symptoms partially explained the relationship between trauma exposure and widespread pain, pain intensity, and polysomatic symptoms. Experiential avoidance did not mediate or moderate the trauma-CS relationship.
CONCLUSIONS - Our findings suggest that trauma exposure is linked to elevated clinical markers of CS but a critical factor in this relationship is the mediating effect of current PTSD symptoms.

Show Abstract · Added September 16, 2019
PURPOSE - The relationship between exposure to abuse and interstitial cystitis/bladder pain syndrome (IC/BPS) is well-documented. However, studies have yet to examine posttraumatic stress disorder (PTSD), which develops following exposure to trauma and worsens health outcomes in chronic pain. We aimed to assess the prevalence and impact of PTSD in patients with IC/BPS, including their relation to genitourinary symptom presentation and widespread pain phenotype.
MATERIALS AND METHODS - We recruited 202 participants with chronic pain from an academic medical center and classified 64 individuals as IC/BPS based on validated epidemiological criteria. Participants completed self-reported questionnaires assessing trauma exposure, PTSD symptoms, emotional distress, pain, and urinary symptoms. Wilcoxon rank-sum tests assessed study aims comparing IC/BPS to other chronic pain.
RESULTS - Although elevated, IC/BPS trauma exposure rates were equivalent to that of other chronic pain conditions in the sample. Despite this equivalence, in comparison, IC/BPS patients had significantly higher rates of PTSD symptoms, with 42% meeting provisional diagnostic criteria for PTSD. Among IC/BPS, those meeting provisional criteria for PTSD had significantly higher incidence of lifetime sexual abuse, childhood trauma, and presentations consistent with the widespread pain phenotype. In IC/BPS, there was no association between PTSD and genitourinary symptoms, but provisional PTSD was associated with more pain, emotional distress, and poorer quality of life.
CONCLUSIONS - We recommend that patients with IC/BPS and widespread pain have ongoing screening and monitoring of PTSD. We recommend using trauma-informed care practices with these patients to increase trust and safety, which could improve treatment compliance and follow-up.

Intensive Care Unit Delirium and Intensive Care Unit-Related Posttraumatic Stress Disorder.
Marra A, Pandharipande PP, Patel MB
(2017) Surg Clin North Am 97: 1215-1235
MeSH Terms: Antipsychotic Agents, Brain Diseases, Cognition Disorders, Conscious Sedation, Critical Care, Critical Illness, Delirium, Early Ambulation, Exercise Therapy, Family, Humans, Pain Measurement, Stress Disorders, Post-Traumatic, Ventilator Weaning
Show Abstract · Added June 26, 2018
Delirium is one of the most common behavioral manifestations of acute brain dysfunction in the intensive care unit (ICU) and is a strong predictor of worse outcome. Routine monitoring for delirium is recommended for all ICU patients using validated tools. In delirious patients, a search for all reversible precipitants is the first line of action and pharmacologic treatment should be considered when all causes have been ruled out, and it is not contraindicated. Long-term morbidity has significant consequences for survivors of critical illness and for their caregivers. ICU patients may develop posttraumatic stress disorder related to their critical illness experience.

Depression and post-traumatic stress disorder in individuals with hereditary hemorrhagic telangiectasia: A cross-sectional survey.
Chaturvedi S, Clancy M, Schaefer N, Oluwole O, McCrae KR
(2017) Thromb Res 153: 14-18
MeSH Terms: Adolescent, Adult, Aged, Aged, 80 and over, Cross-Sectional Studies, Depression, Depressive Disorder, Female, Humans, Male, Middle Aged, Prevalence, Stress Disorders, Post-Traumatic, Surveys and Questionnaires, Telangiectasia, Hereditary Hemorrhagic, Young Adult
Show Abstract · Added April 9, 2017
INTRODUCTION - Hereditary hemorrhagic telangiectasia (HHT) is characterized by frequent severe bleeding, particularly epistaxis, and life-threatening complications including stroke, brain abscess and heart failure. The psychological impact of HHT is not known. We conducted this cross sectional study to determine the prevalence of depression and post-traumatic stress disorder (PTSD) related to HHT.
METHODS - A survey tool comprising demographic and clinical information and two validated self-administered questionnaires, the PTSD checklist for DSM-5 (PCL-5) and Beck Depression Inventory-II (BDI-II), was distributed to individuals with HHT. Associations with clinical and demographic variables with depression and PTSD were evaluated in a logistic regression model.
RESULTS - A total of 222 individuals responded to the survey. Of these, 185 completed either the BDI II or PCL-5 and were included in the analysis. Median age was 54years and 142 (76.8%) were female. An existing diagnosis of depression, anxiety disorder and PTSD was present in 81 (43.8%), 59 (31.9%) and 16(8.6%) respondents, respectively. BDI-II scores>13 indicating at least mild depressive symptoms were present in 142 (88.7%) patients and 52 (28.1%) patients had a positive screen for PTSD (PCL-5 score≥38). On multivariable analysis, depression [OR 2.17 (95% CI 1.045-4.489), p=0.038], anxiety disorder [OR 2.232 (95% CI 1.066-4.676), p=0.033], and being unemployed [OR 2.234 (95% CI 1.46-4.714), p=0.019) were associated with PTSD.
CONCLUSION - We report a high prevalence of depressive and PTSD symptoms in individuals with HHT. While selection bias may lead to overestimation of prevalence in this study, our results are concerning and clinicians should remain vigilant for signs of psychological distress and consider screening for these disorders.

(2017) Thromb Res 151: 51-56
MeSH Terms: Adult, Cross-Sectional Studies, Depression, Female, Humans, Male, Middle Aged, Prevalence, Purpura, Thrombotic Thrombocytopenic, Risk Factors, Stress Disorders, Post-Traumatic, Surveys and Questionnaires, Survivors, Unemployment
Show Abstract · Added January 24, 2017
INTRODUCTION - Survivors of thrombotic thrombocytopenic purpura (TTP) have high rates of chronic morbidities including neurocognitive complications and depression. There is limited information regarding the psychological consequences of TTP. We conducted this cross sectional study to estimate the prevalence of symptoms of PTSD and depression in survivors of TTP.
METHODS - An online survey tool comprising demographic and clinical information and two validated self-administered questionnaires, the PTSD checklist for DSM-5 (PCL-5) and Beck Depression Inventory-II (BDI-II), was distributed to individuals with TTP. Multivariable regression was used to identify clinical and demographic associations of depression and PTSD.
RESULTS - A total of 236 individuals completed either the BDI II or PCL-5 and were included in the analysis. Median age was 44years and 87.3% were female. Median time from diagnosis was 80months. BDI-II scores >13 indicating at least mild depressive symptoms were present in 80.8% individuals (15.8%, 28.2%, and 36.8% with mild, moderate and severe symptoms, respectively) and 35.1% had a positive screen for PTSD (PCL-5 score≥38). A previous diagnosis of depression [OR 3.65 (95% CI 1.26-10.57); p=0.017] and unemployment attributed to TTP [OR 5.86 (95% CI 1.26-27.09); p=0.024] were associated with depression. Younger age (p=0.017), a pre-existing anxiety disorder [OR 3.57 (95% CI 1.76-7.25), p<0.001], and unemployment attributable to TTP [OR 6.42 (95% CI 2.75-415.00), p<0.001] were associated with PTSD.
CONCLUSION - We report a high prevalence of PTSD and depression in TTP survivors. These results are concerning and indicate a need for further investigation to better define this association and its consequences.

Thalamic Functional Connectivity in Mild Traumatic Brain Injury: Longitudinal Associations With Patient-Reported Outcomes and Neuropsychological Tests.
Banks SD, Coronado RA, Clemons LR, Abraham CM, Pruthi S, Conrad BN, Morgan VL, Guillamondegui OD, Archer KR
(2016) Arch Phys Med Rehabil 97: 1254-61
MeSH Terms: Adolescent, Adult, Brain, Brain Concussion, Case-Control Studies, Depression, Female, Humans, Male, Middle Aged, Neuropsychological Tests, Pain, Patient Reported Outcome Measures, Post-Concussion Syndrome, Prospective Studies, Stress Disorders, Post-Traumatic, Thalamus, Young Adult
Show Abstract · Added March 16, 2018
OBJECTIVES - (1) To examine differences in patient-reported outcomes, neuropsychological tests, and thalamic functional connectivity (FC) between patients with mild traumatic brain injury (mTBI) and individuals without mTBI and (2) to determine longitudinal associations between changes in these measures.
DESIGN - Prospective observational case-control study.
SETTING - Academic medical center.
PARTICIPANTS - A sample (N=24) of 13 patients with mTBI (mean age, 39.3±14.0y; 4 women [31%]) and 11 age- and sex-matched controls without mTBI (mean age, 37.6±13.3y; 4 women [36%]).
INTERVENTIONS - Not applicable.
MAIN OUTCOME MEASURES - Resting state FC (3T magnetic resonance imaging scanner) was examined between the thalamus and the default mode network, dorsal attention network, and frontoparietal control network. Patient-reported outcomes included pain (Brief Pain Inventory), depressive symptoms (Patient Health Questionnaire-9), posttraumatic stress disorder ([PTSD] Checklist - Civilian Version), and postconcussive symptoms (Rivermead Post-Concussion Symptoms Questionnaire). Neuropsychological tests included the Delis-Kaplan Executive Function System Tower test, Trails B, and Hotel Task. Assessments occurred at 6 weeks and 4 months after hospitalization in patients with mTBI and at a single visit for controls.
RESULTS - Student t tests found increased pain, depressive symptoms, PTSD symptoms, and postconcussive symptoms; decreased performance on Trails B; increased FC between the thalamus and the default mode network; and decreased FC between the thalamus and the dorsal attention network and between the thalamus and the frontoparietal control network in patients with mTBI as compared with controls. The Spearman correlation coefficient indicated that increased FC between the thalamus and the dorsal attention network from baseline to 4 months was associated with decreased pain and postconcussive symptoms (corrected P<.05).
CONCLUSIONS - Findings suggest that alterations in thalamic FC occur after mTBI, and improvements in pain and postconcussive symptoms are correlated with normalization of thalamic FC over time.

Show Abstract · Added June 14, 2016
RATIONALE - The incidence and risk factors of post-traumatic stress disorder (PTSD) related to the intensive care unit (ICU) experience have not been reported in a mixed veteran and civilian cohort.
OBJECTIVES - To describe the incidence and risk factors for ICU-related PTSD in veterans and civilians.
METHODS - This is a prospective, observational, multicenter cohort enrolling adult survivors of critical illness after respiratory failure and/or shock from three Veterans Affairs and one civilian hospital. After classifying those with/without preexisting PTSD (i.e., PTSD before hospitalization), we then assessed all subjects for ICU-related PTSD at 3 and 12 months post hospitalization.
MEASUREMENTS AND MAIN RESULTS - Of 255 survivors, 181 and 160 subjects were assessed for ICU-related PTSD at 3- and 12-month follow-up, respectively. A high probability of ICU-related PTSD was found in up to 10% of patients at either follow-up time point, whether assessed by PTSD Checklist Event-Specific Version (score ≥ 50) or item mapping using the Diagnostic and Statistical Manual of Mental Disorders-IV (DSM-IV). In the multivariable regression, preexisting PTSD was independently associated with ICU-related PTSD at both 3 and 12 months (P < 0.001), as was preexisting depression (P < 0.03), but veteran status was not a consistent independent risk factor for ICU-related PTSD (3-month P = 0.01, 12-month P = 0.48).
CONCLUSIONS - This study found around 1 in 10 ICU survivors experienced ICU-related PTSD (i.e., PTSD anchored to their critical illness) in the year after hospitalization. Preexisting PTSD and depression were strongly associated with ICU-related PTSD.

The Role of Anxiety Control and Treatment Implications of Informant Agreement on Child PTSD Symptoms.
Humphreys KL, Weems CF, Scheeringa MS
(2017) J Clin Child Adolesc Psychol 46: 903-914
MeSH Terms: Anxiety, Child, Female, Humans, Male, Parent-Child Relations, Stress Disorders, Post-Traumatic
Show Abstract · Added March 3, 2020
The goal of this study is to examine parent and child agreement of child posttraumatic stress disorder (PTSD) symptoms pre- and posttreatment, as well as potential moderators of agreement including treatment responder status, child anxiety control, and parent self-reported PTSD symptoms. We examined child self-reported and parent-reported child PTSD symptoms from the Diagnostic Interview Schedule for Children. Of the 141 parent-child pairs, the mean age of children was 12.72 (SD = 3.40), 53% were female, and 54% were Black. A subsample of participants (n = 47) was assessed after completion of a cognitive behavioral therapy treatment for PTSD. Moderate levels of agreement were found at baseline, though Criterion D (increased arousal) symptoms had lower levels of agreement than the other symptom clusters. Symptom agreement was lower at posttreatment. Treatment responders had higher levels of baseline informant agreement than treatment nonresponders. Child perceived anxiety control significantly moderated informant agreement, such that pairs with children who had high levels of perceived control of their anxiety had lower PTSD symptom agreement where children reported lower symptoms relative to their parents. Contrary to expectations, parent self-reported PTSD did not moderate parent-child symptom agreement. Factors associated with higher parent-child agreement of child PTSD symptoms were being a PTSD treatment responder and children with lower perceived anxiety control. These findings have potential implications for determining those who may benefit from greater symptom monitoring over the course of intervention and potential alternative intervention approaches.

Show Abstract · Added February 12, 2015
Hyperarousal and sleep disturbances are common, debilitating symptoms of post-traumatic stress disorder (PTSD). PTSD patients also exhibit abnormalities in quantitative electroencephalography (qEEG) power spectra during wake as well as rapid eye movement (REM) and non-REM (NREM) sleep. Selective serotonin reuptake inhibitors (SSRIs), the first-line pharmacological treatment for PTSD, provide modest remediation of the hyperarousal symptoms in PTSD patients, but have little to no effect on the sleep-wake architecture deficits. Development of novel therapeutics for these sleep-wake architecture deficits is limited by a lack of relevant animal models. Thus, the present study investigated whether single prolonged stress (SPS), a rodent model of traumatic stress, induces PTSD-like sleep-wake and qEEG spectral power abnormalities that correlate with changes in central serotonin (5-HT) and neuropeptide Y (NPY) signaling in rats. Rats were implanted with telemetric recording devices to continuously measure EEG before and after SPS treatment. A second cohort of rats was used to measure SPS-induced changes in plasma corticosterone, 5-HT utilization, and NPY expression in brain regions that comprise the neural fear circuitry. SPS caused sustained dysregulation of NREM and REM sleep, accompanied by state-dependent alterations in qEEG power spectra indicative of cortical hyperarousal. These changes corresponded with acute induction of the corticosterone receptor co-chaperone FK506-binding protein 51 and delayed reductions in 5-HT utilization and NPY expression in the amygdala. SPS represents a preclinical model of PTSD-related sleep-wake and qEEG disturbances with underlying alterations in neurotransmitter systems known to modulate both sleep-wake architecture and the neural fear circuitry.

MeSH Terms: African Americans, Catechol O-Methyltransferase, Child, Preschool, European Continental Ancestry Group, Female, Gene Frequency, Genotype, Humans, Male, Polymorphism, Single Nucleotide, Stress Disorders, Post-Traumatic
Show Abstract · Added March 3, 2020
OBJECTIVE - The present study sought to replicate previous findings of an association between the Catechol-O-methyltransferase (COMT) val158met polymorphism with posttraumatic stress disorder (PTSD) and symptomatology in a novel age group, preschool children.
METHODS - COMT genotype was determined in a sample of 171 3-6-year-old trauma-exposed children. PTSD was assessed with a semistructured interview. Accounting for sex, trauma type, and age, genotype was examined in relation to categorical and continuous measures of PTSD both controlling for race and within the two largest racial categories (African American [AA] and European American [EA]).
RESULTS - Race significantly moderated the association between genotype and PTSD. Specifically, the genotype associated with increased PTSD symptoms in one racial group had the opposite association in the other racial group. For AA children the met/met genotype was associated with more PTSD symptoms. However, for EA children, val allele carriers had more PTSD symptoms. Whereas every AA child with the met/met genotype met criteria for PTSD, none of the EA children with the met/met genotype did. This genetic association with COMT genotype, in both races but in opposite directions, was most associated with increased arousal symptoms.
CONCLUSIONS - These findings replicate previous findings in participants of African descent, highlight the moderating effect of race on the association between COMT genotype and PTSD, and provide direct evidence that consideration of population stratification within gene-by-environment studies is valuable to prevent false negative findings.
