Treatment of pharmacotherapy-refractory posttraumatic stress disorder among Cambodian refugees: a pilot study of combination treatment with cognitive-behavior therapy vs sertraline alone. A pilot randomized controlled trial of combined trauma-focused CBT and sertraline for childhood PTSD symptoms. Augmentation of sertraline with prolonged exposure in the treatment of posttraumatic stress disorder. Paroxetine CR augmentation for posttraumatic stress disorder refractory to prolonged exposure therapy.
Cambodian refugees with posttraumatic stress disorder (PTSD) represent a cohort in severe need of treatment, but little information is available to guide treatment choices. We selected a sample of pharmacotherapy-refractory individuals to test the efficacy of combination treatment with sertraline and cognitive-behavior therapy (CBT) for treating PTSD. Participants in this pilot study were ten Khmer-speaking women who had been at a mean age of 22-26 years during the Pol Pot period (1975-1979). These patients were randomly assigned to either sertraline alone or combined treatment. We found that combined treatment offered additional benefit in the range of medium to large effect sizes for PTSD and associated symptoms. Our findings indicate that substantial gains can be achieved by adding CBT to pharmacotherapy for PTSD, and that a program of CBT emphasizing information, exposure, and cognitive-restructuring can be successfully modified for Khmer-speaking refugees. To examine the potential benefits of adding a selective serotonin reuptake inhibitor, sertraline, versus placebo, to trauma-focused cognitive-behavioral therapy (TF-CBT) for improving posttraumatic stress disorder and related psychological symptoms in children who have experienced sexual abuse.
                Twenty-four 10- to 17-year-old female children and adolescents and their primary caretakers were randomly assigned to receive TF-CBT + sertraline or TF-CBT + placebo for 12 weeks.
                Both groups experienced significant improvement in posttraumatic stress disorder and other clinical outcomes from pre- to posttreatment with no significant group x time differences between groups except in Child Global Assessment Scale ratings, which favored the TF-CBT + sertraline group.
                Only minimal evidence suggests a benefit to adding sertraline to TF-CBT. A drawback of adding sertraline was determining whether TF-CBT or sertraline caused clinical improvement for children with comorbid depression. Current evidence therefore supports an initial trial of TF-CBT or other evidence-supported psychotherapy for most children with PTSD symptoms before adding medication. The present study was designed to determine whether augmenting sertraline with prolonged exposure (PE) would result in greater improvement than continuation with sertraline alone. Outpatient men and women with chronic PTSD completed 10 weeks of open label sertraline and then were randomly assigned to five additional weeks of sertraline alone (n = 31) or sertraline plus 10 sessions of twice-weekly PE (n = 34). Results indicated that sertraline led to a significant reduction in PTSD severity after 10 weeks but was associated with no further reductions after five more weeks. Participants who received PE showed further reduction in PTSD severity. This augmentation effect was observed only for participants who showed a partial response to medication. Little is known about the efficacy of "next step" strategies for patients with post-traumatic stress disorder (PTSD) who remain symptomatic despite treatment. This study prospectively examines the relative efficacy of augmentation of continued prolonged exposure therapy (PE) with paroxetine CR versus placebo for individuals remaining symptomatic despite a course of PE.
                Adult outpatients meeting DSM-IV criteria for PTSD were recruited from February 2003 to September 2005 at 4 academic centers. Phase I consisted of 8 sessions of individual PE over a 4- to 6-week period. Participants who remained symptomatic, defined as a score of >or= 6 on the Short PTSD Rating Interview (SPRINT) and a Clinical Global Impressions-Severity of Illness scale (CGI-S) score >or= 3, were randomly assigned to the addition of paroxetine CR or matched placebo to an additional 5 sessions of PE (Phase II).
                Consistent with prior studies, the 44 Phase I completers improved significantly with initial PE (SPRINT: paired t = 7.6, df = 41, p < .0001; CGI-S: paired t = 6.37, df = 41, p < .0001). Counter to our hypothesis, however, we found no additive benefit of augmentation of continued PE with paroxetine CR compared to pill placebo for the 23 randomly assigned patients, with relatively minimal further gains overall in Phase II.
                Although replication with larger samples is needed before definitive conclusions can be drawn, our data do not support the addition of paroxetine CR compared with placebo to continued PE for individuals with PTSD who remain symptomatic after initial PE, suggesting that the development of novel treatment approaches for PTSD refractory to PE is needed.

There is not enough evidence available to support or refute the effectiveness of combined psychological therapy and pharmacotherapy compared to either of these interventions alone. Further large randomised controlled trials are urgently required.
