Stress responses after pediatric bone marrow transplantation: preliminary results of a prospective longitudinal study.

This paper reports the preliminary findings of a longitudinal prospective study of young children undergoing bone marrow transplantation. Symptoms of post-traumatic stress were seen in these children up to 12 months after transplant. The bone marrow transplantation survivors demonstrated more denial and avoidance and fewer arousal symptoms than has been noted in children traumatized by a violent life threat, such as a sniper attack. These data suggest the use of post-traumatic stress as a model in understanding some of the symptoms of pediatric bone marrow transplantation survivors and may be applicable to other children exposed to the double life threat of serious illness and intensive medical intervention.

Prevalence and Predictors of Posttraumatic Stress Disorder in Adult Survivors of Childhood Cancer

OBJECTIVE: This study compared the prevalence of symptoms of posttraumatic stress disorder (PTSD), with functional impairment and/or clinical distress, among very long-term survivors of childhood cancer and a group of healthy siblings. METHODS: A total of 6542 childhood cancer survivors >18 years of age who received diagnoses between 1970 and 1986 and 368 siblings of cancer survivors completed a comprehensive demographic and health survey. RESULTS: A total of 589 survivors (9%) and 8 siblings (2%) reported functional impairment and/or clinical distress in addition to the set of symptoms consistent with a full diagnosis of PTSD. Survivors had more than fourfold greater risk of PTSD, compared with siblings (odds ratio [OR]: 4.14 [95% confidence interval [CI]: 2.08–8.25]). With controlling for demographic and treatment variables, increased risk of PTSD was associated with educational level of high school or less (OR: 1.51 [95% CI: 1.16–1.98]), being unmarried (OR: 1.99 [95% CI: 1.58–2.50]), having annual income below

Traumatic Stress Symptoms in Adolescent Organ Transplant Recipients

20000 (OR: 1.63 [95% CI: 1.21–2.20]), and being unemployed (OR: 2.01 [95% CI: 1.62–2.51]). Intensive treatment also was associated with increased risk of full PTSD (OR: 1.36 [95% CI: 1.06–1.74]). CONCLUSIONS: PTSD was reported significantly more often by survivors of childhood cancer than by sibling control subjects. Although most survivors apparently are faring well, a subset reported significant impairment that may warrant targeted intervention.

Perceived Positive Impact of Cancer Among Long-term Survivors of Childhood Cancer: a report from the Childhood Cancer Survivor Study

Objective. Symptoms of posttraumatic stress disorder (PTSD) after life-threatening medical illness have been found to predict poor outcome in preliminary studies of adults and children. However, these symptoms are rarely recognized in general medical or pediatric settings. Here we report on the first large investigation to assess prevalence and correlates of self-reported symptoms of posttraumatic stress in a nonreferred sample of adolescent liver, heart, and kidney transplant recipients. Methods. One hundred four adolescents, ages 12 to 20 years (mean: 15.7; SD: 2.1), completed and returned the University of California, Los Angeles, PTSD Index for the Diagnostic and Statistical Manual of Mental Disorders. All participants were at least 1 year post-initial transplant and were fluent speakers of English and/or Spanish. Results. More than 16% of the adolescents met all symptom criteria for PTSD, and an additional 14.4% met 2 of 3 symptom-cluster criteria. Regression analysis indicated no effect of gender, ethnicity, age at interview, organ type, time since transplant, or age at transplant. Conclusions. As has been found with other life-threatening pediatric conditions, solid organ transplantation can precipitate symptoms of posttraumatic stress. Symptoms are not predicted by what would be considered objective factors increasing life threat, suggesting a greater salience of subjective appraisal of threat, as has been seen in studies of childhood cancer survivors.

Allostatic Load in Women With and Without PTSD Symptoms

Investigations examining psychosocial adjustment among childhood cancer survivors have focused primarily on negative effects and psychopathology. Emergent literature suggests the existence of positive impact or adjustment experienced after cancer, as well. The purpose of this study is to examine the distribution of Perceived Positive Impact (PPI) and its correlates in young adult survivors of childhood cancer.

Evaluating non-adherence to immunosuppressant medications in pediatric liver transplant recipients.

Allostatic load (AL) is the term used to describe cumulative physiological wear and tear that results from repeated efforts to adapt to stressors over time. Operationalized as a composite index of biological risk factors (e.g., blood pressure, cholesterol, glycosylated hemoglobin, and cortisol, norepinephrine, and epinephrine), AL has been shown to increase with age, predict long–term morbidity and mortality among the elderly, and be associated with low parent education in a large adolescent sample. However, AL has not yet been studied in samples with putative “high stress” or posttraumatic stress disorder (PTSD). Accordingly, AL was measured in women with high acute and chronic stress: mothers of pediatric cancer survivors with and without PTSD and control mothers of healthy children. AL emerged in a “dose–dependent” ranking from high to low: cancer mothers meeting all criteria for PTSD, cancer mothers with no or low symptoms, and control mothers, respectively (p < .001). Effects were not altered by self–reported sleep quality or substance use (tobacco, caffeine, alcohol, or drugs) and remained significant when analyzing AL without cortisol or catecholamines. Results indicate elevated AL can be detected in relatively young women with high stress histories and particularly those with PTSD. Future prospective studies must evaluate whether this pattern represents an accelerated aging process and increased risk of disease.

Posttraumatic stress responses in children with life-threatening illnesses

Abstract:  Non‐adherence with recommended immunosuppressant medications is common post‐pediatric liver transplant and is the most important reason for organ rejection in long‐term survivors. However, there is currently no validated, standard method to measure adherence, with a well‐defined threshold, making it extremely difficult to evaluate interventions to improve adherence. Previous studies have suggested that the degree of fluctuation of medication blood levels over time can provide an idea about how regularly the medication is being taken. The present study, conducted at UCLA medical center, sought to identify a specific threshold value of the s.d. of individual tacrolimus blood levels in pediatric liver transplant recipients which would be associated with rejection episodes in these patients. A threshold of 3.0 has been identified in other studies, and was supported by the analysis of retrospective data from 96 subjects. However, further analysis found that a s.d. of 2.5 appeared to have a better fit with the data. These findings suggest the utility of monitoring the s.d. of routine tacrolimus blood levels in pediatric liver transplant recipients for detecting non‐adherence to immunosuppressant medication prior to clinical rejection, allowing earlier interventions.

Posttraumatic Stress in Survivors of Childhood Cancer and Mothers: Development and Validation of the Impact of Traumatic Stressors Interview Schedule (ITSIS)

Posttraumatic stress symptoms have been reported in response to various serious medical illnesses in adults and children. Not surprisingly, posttraumatic stress is probably more common in response to acute, life-threatening, events that are related to the illness. Emerging data suggest that children often experience life-saving medical procedures as traumatic, which puts caretakers and medical personnel in the role of perpetrators for the children. Trauma symptoms are also reported as common and severe in caregivers. Both of these issues have been previously poorly understood and should be addressed in assessment and treatment. As with other traumatic events, developmental considerations, the nature and severity of the event itself, social supports, and premorbid exposure to negative life events are also important issues to consider in developing appropriate interventions. The importance of developing prevention and treatment for PTSD in medically ill children and adults includes increased morbidity and mortality (e.g., nonadherence to medications) and psychiatric sequelae and decreased quality of life. Obstacles to systematic study of a psychiatric intervention for this group include difficulties assessing multidrug regimens and cognitive treatment effects in this group. The relative stability of social supports and the potential use of preventive measures make this an attractive population for intervention. Clinicians and researchers are encouraged to work together to develop and use uniform screening and assessment methods that will help to identify cases and facilitate the multicenter trials that are vital to increasing knowledge in this patient population.

Spirituality in children and adolescents: research findings and implications for clinicians and researchers

This study presents initial data validating the use of a new instrument, the Impact of Traumatic Stressors Interview Schedule (ITSIS), to assess the occurrence of cancer-related posttraumatic stress in childhood cancer survivors and their mothers. Sixty-six child/adolescent cancer survivors and 64 of their mothers, as well as 130 young adult survivors, completed the ITSIS and other measures of posttraumatic stress and general distress. Five ITSIS factors were identified for the mothers and for the young adult survivors, and three ITSIS factors were identified for the child/adolescent survivors. Factors in all three samples reflected symptoms of posttraumatic distress, concern over medical late effects, communication, and changes in self due to cancer. Only young adult survivors had a factor reflecting a positive engagement with the cancer history. Factors correlated with validation measures in predicted ways. The findings further the conceptualization of posttraumatic stress in pediatric cancer by describing the traumatic experience for survivors and mothers. Comparing factors across samples allows an examination of different influences of cancer within families and over the course of development.

PSYCHIATRIC SEQUELAE IN SERIOUSLY ILL CHILDREN AND THEIR FAMILIES

Spirituality is a powerful force in the lives of children. Although spirituality has only recently begun to be a focus for psychiatric research, initial qualitative data suggest that children experience themselves as spiritual beings and that understanding and connecting with them around their spiritual lives can be an important adjunct to treatment. Clinicians should feel free to ask about a childs spiritual life and to work with the family using their spiritual resources if they are perceived to be beneficial in helping the child and family cope with their current situation. Because the work with childrens spirituality is in its preliminary stages, qualitative methodology is still the recommended research method for investigating questions in this research area.
