Nefazodone for PTSD

Assessment and management of pediatric iatrogenic medical trauma

Medically ill children are often exposed to traumatizing situations within the medical setting. Approximately 25-30 % of medically ill children develop posttraumatic stress symptoms and 10-20 % of them meet criteria for posttraumatic stress disorder. Parents of medically ill children are at even higher risk for posttraumatic stress symptoms. Most children and parents will experience resolution of mild trauma symptoms without formal psychological or psychiatric treatment. Posttraumatic stress symptoms are associated with medical nonadherence, psychiatric co-morbidities, and poorer health status. Therefore, evidenced-based trauma-focused treatment is indicated for those who remain highly distressed or impaired. This paper reviews approaches to the assessment and management of pediatric iatrogenic medical trauma within a family-based framework.

Psychopharmacologic treatment of traumatized youth

PURPOSE OF REVIEW

To review and summarize existing literature regarding pharmacological interventions for post-traumatic stress disorder (PTSD) in children and adolescents. A literature search limited to articles focused on the pharmacological treatment of children aged 0-18 years with a history of trauma and/or PTSD was conducted through the National Library of Medicine and PsychInfo, 1967-present, and each citation manually reviewed.

RECENT FINDINGS

Pharmacologic trials for pediatric PTSD are limited in scope and number, with one small double-blind, randomized controlled trial of the selective serotonin reuptake inhibitor (SSRI) sertraline. Two brief, small, double-blind, randomized controlled trials of imipramine for children and adolescents with acute stress disorder have been conducted, with mixed results. Only case reports or open-labeled trials have been conducted with alpha-adrenergic agents, other antidepressants, atypical antipsychotics, and antiepileptic agents.

SUMMARY

Data supporting the use of medications in the treatment of PTSD in children and adolescents are limited. SSRIs show promise and deserve additional study, but conclusive support for their use is not available as it is in adults. Additional research is needed, with other drugs of interest including other antidepressants, alpha-adrenergic agents, and possibly the antiepileptic agent carbamazepine.

Psychological impact of trauma on developing children and youth

All too often, children and adolescents are exposed to traumatic events that lead to physical injury in many cases, psychological perturbation in most cases, and enduring psychological reactions, notably posttraumatic stress disorder, in a minority of individuals. This sequence of events can affect later development, learning, emotions, and behavior. In the process of caring for the physical injury, it is important for the primary care practitioner (PCP) to correctly interpret these presentations and anticipate the need for specific assessments, immediate intervention, referral, and follow-up. This report provides the foundation for such actions on the part of the PCP.

The pharmacological management of childhood anxiety disorders: a review

RATIONALE

Pediatric anxiety is a prevalent psychiatric disorder that may have important implications for school, social, and academic function. Psychopharmacological approaches to the treatment of pediatric anxiety have expanded over the past 20 years and increasing empirical evidence helps guide current clinical practice.

OBJECTIVE

To review studies which examine the pharmacological treatment of pediatric anxiety disorders, including obsessive-compulsive disorder and to summarize treatment implications.

METHODS

All relevant studies were searched using MEDLINE and PsycINFO search engines, supplemented by a manual bibliographical search; studies published between 1985 and 2006 that met inclusion criteria were examined.

RESULTS

This article provides a systematic review of the psychopharmacological treatment of pediatric anxiety disorders based on available empirical evidence, with a focus on randomized controlled trials. General treatment principles and pharmacological management of specific pediatric anxiety disorders are also reviewed.

CONCLUSION

There is good evidence to support the efficacy of several pharmacological agents including the selective serotonin reuptake inhibitors to treat pediatric anxiety and obsessive-compulsive disorder, although there are still many unanswered questions.

Psychopharmacologic treatment of pediatric anxiety disorders

This article reviews the psychopharmacologic treatment of child and adolescent anxiety disorders and is divided into the following sections: historical background, general treatment principles, obsessive-compulsive disorder, other anxiety disorders, including separation anxiety disorders, generalized anxiety disorder, and social phobia, elective mutism, and post-traumatic stress disorder and specific phobia. Short-term and long-term psychopharmacologic treatment strategies are reviewed, as are approaches for managing comorbidity and treatment-refractory cases. This article is organized by diagnostic categories rather than by medication classes to emphasize the clinical perspective.

A placebo-controlled study of nefazodone for the treatment of chronic posttraumatic stress disorder: a preliminary study

Nefazodone is a unique serotonergic antidepressant that acts as both a presynaptic serotonin reuptake inhibitor and a postsynaptic 5-hydroxytryptamine 2A receptor antagonist. Based on the positive results of open-label trials of nefazodone, including one from our group, we tested nefazodone's efficacy in the treatment of posttraumatic stress disorder (PTSD) under placebo-controlled conditions. Forty-one patients with chronic PTSD, predominantly male combat veterans, were enrolled in a randomized, double-blind, placebo-controlled 12-week trial of nefazodone. The primary outcome measure was the Clinician-Administered PTSD Scale. Fifteen patients were randomized to placebo and 26 were randomized to nefazodone. In a repeated-measures analysis of variance with last observation carried forward, patients on nefazodone showed a significant improvement in the percentage change of Clinician-Administered PTSD Scale Total score from baseline compared with those on placebo (P = 0.04; effect size = 0.6). Sample size was not powered to test group differences in the Clinician-Administered PTSD Scale criterion B, C, or D subscale. However, the criterion D subscale showed significant improvement in patients treated with nefazodone compared with those treated with placebo (P = 0.007). In addition, the Hamilton Rating Scale for Depression showed significant improvement compared with placebo (P = 0.008). The nefazodone group also reported an improvement on the PTSD Checklist (self-report scale; P = 0.08) and the Clinician-Administered Dissociative States Scale (P = 0.06). This pilot study supports the efficacy of nefazodone for the treatment of PTSD. However, larger placebo-controlled studies in more diverse patient population are warranted.

Pharmacologic treatment approaches for children and adolescents with posttraumatic stress disorder

Posttraumatic stress disorder is a common cause of morbidity in children and adolescents. The disorder in youth is similar to that in adults, with high rates of psychiatric comorbidity. Children seem to be more sensitive to the effects of trauma, and early life trauma exposure may induce a complex sequence of events that leads to the development of multiple psychiatric disorders in adulthood. The state of knowledge regarding medication treatments for children and adolescents is in the earliest stages of development. There are no well-conducted, randomized clinical trials to guide practitioners. Medication may play an important role in reducing debilitating symptoms of PTSD and providing a buffer for children while they confront difficult material in therapy and may help to improve their general functioning in day-to-day life. Given the various medications with potential usefulness in PTSD, it is helpful to use a stepwise approach to treatment. As a general principal, broad-spectrum agents, such as the SSRIs, are a good first choice. The SSRIs have efficacy in treating the core symptoms of PTSD and conditions such as the anxiety disorders and depression that commonly co-occur with PTSD. These agents also improve social and occupational functioning and an individual's perception of improved quality of life [41, 45, 46]. Although the SSRIs are generally effective for a broad spectrum of problems, clinicians should systematically monitor for the persistence of symptoms that do not respond to these agents. For example, despite significant improvements in core PTSD symptoms in one study that used sertraline, little improvement was seen in patients' comorbid anxiety and depressive symptoms [41]. This finding demonstrates the value of continuous symptom monitoring and shows that residual or comorbid symptoms may require a different medication to augment effective SSRI treatment for PTSD. A reasonable approach is to begin with a broad-spectrum agent, such as an SSRI, which should target anxiety, mood, and reexperiencing symptoms. Adrenergic agents, such as clonidine, used either alone or in combination with an SSRI may be useful when symptoms of hyperarousal and impulsivity are problematic. Supplementing with a mood stabilizer may be necessary in severe affective dyscontrol. Similarly, introduction of an atypical neuroleptic agent may be necessary in cases of severe self-injurious behavior, dissociation, psychosis, or aggression. Comorbid conditions such as ADHD should be targeted with pharmacotherapy known to be effective, such as psychostimulants or newer agents such as atomoxetine. Pharmacologic treatment of PTSD in childhood is one approach to alleviating the acute and chronic symptoms of the disorder. Despite the lack of well-designed, randomized, controlled trials that support efficacy, medication can be used in a rational and safe manner. Reduction in even one disabling symptom, such as insomnia or hyperarousal, may have a positive ripple effect on a child's overall functioning. Pharmacotherapy is typically used as one component of a more comprehensive multiple modality treatment package, including psychoeducation of the parent and child, focused exposure-based psychotherapy with adjunctive family therapy when indicated, and long-term booster interventions that use an admixture of psychodynamic, cognitive-behavioral, and pharmacologic interventions.

Post-traumatic stress disorder in children and adolescents: epidemiology, diagnosis and treatment options

Post-traumatic stress disorder (PTSD) is a common psychiatric condition in childhood and adolescence. Rates vary widely depending upon the type of trauma exposure. Interpersonal traumas, such as rape or physical abuse, are more likely to result in PTSD than exposure to natural or technological disaster. Clinical presentations are exceedingly complex and children with PTSD are at increased risk of having comorbid psychiatric diagnoses. Because of its complexity and frequent occurrence with other disorders, assessment of PTSD necessitates a broad-based evaluation utilizing multiple informations and structured instruments specific to the symptoms of PTSD in youth. Cognitive-behavioral therapy (CBT) is the treatment of first choice. Pharmacological agents for PTSD treatment have received little empirical investigation in childhood. Pharmacological treatment is used to target disabling symptoms of the disorder, which limit psychotherapy or life functioning, by helping children to tolerate working through distressful material in therapy and life. Pharmacological treatment should be based on a stepwise approach utilizing broad spectrum medications such as the selective serotonin reuptake inhibitors as first-line agents. Comorbid conditions should be identified and treated with appropriate medication or psychosocial interventions. Treatment algorithms are provided to guide rational medication strategies for children and adolescents with PTSD, subsyndromal PTSD, and in PTSD that is comorbid with other psychiatric conditions of childhood. Reduction in even one debilitating symptom of PTSD can improve a child's overall functioning across multiple domains.
