Cognitive Behavioral Therapy, Sertraline, or a Combination in Childhood Anxiety

Abstract: Background Anxiety disorders are common psychiatric conditions affecting children and adolescents. Although cognitive behavioral therapy and selective serotonin-reuptake inhibitors have shown efficacy in treating these disorders, little is known about their relative or combined efficacy. Methods In this randomized, controlled trial, we assigned 488 children between the ages of 7 and 17 years who had a primary diagnosis of separation anxiety disorder, generalized anxiety disorder, or social phobia to receive 14 sessions of cognitive behavioral therapy, sertraline (at a dose of up to 200 mg per day), a combination of sertraline and cognitive behavioral therapy, or a placebo drug for 12 weeks in a 2:2:2:1 ratio. We administered categorical and dimensional ratings of anxiety severity and impairment at baseline and at weeks 4, 8, and 12. Results The percentages of children who were rated as very much or much improved on the Clinician Global Impression–Improvement scale were 80.7% for combination therapy (P<0.001), 59.7% for cognitive behavioral therapy (P<0.001), and 54.9% for sertraline (P<0.001); all therapies were superior to placebo (23.7%). Combination therapy was superior to both monotherapies (P<0.001). Results on the Pediatric Anxiety Rating Scale documented a similar magnitude and pattern of response; combination therapy had a greater response than cognitive behavioral therapy, which was equivalent to sertraline, and all therapies were superior to placebo. Adverse events, including suicidal and homicidal ideation, were no more frequent in the sertraline group than in the placebo group. No child attempted suicide. There was less insomnia, fatigue, sedation, and restlessness associated with cognitive behavioral therapy than with sertraline. Conclusions Both cognitive behavioral therapy and sertraline reduced the severity of anxiety in children with anxiety disorders; a combination of the two therapies had a superior response rate.

Five-Year Outcome for Maintenance Therapies in Recurrent Depression

Abstract: • We conducted a randomized 3-year maintenance trial in 128 patients with recurrent depression who had responded to combined short-term and continuation treatment with imipramine hydrochloride and interpersonal psychotherapy. A five-cell design was used to determine whether a maintenance form of interpersonal psychotherapy alone or in combination with medication could play a significant role in the prevention of recurrence. A second question was whether maintaining antidepressant medication at the dosage used to treat the acute episode rather than decreasing to a "maintenance" dosage would provide prophylaxis superior to that observed in earlier trials in which a maintenance dosage strategy was employed. Survival analysis demonstrated a highly significant prophylactic effect for active imipramine hydrochloride maintained at an average dose of 200 mg and a modest prophylactic effect for monthly interpersonal psychotherapy. We conclude that active imipramine hydrochloride maintained at an average dose of 200 mg is an effective means of preventing recurrence and that monthly interpersonal psychotherapy serves to lengthen the time between episodes in patients not receiving active medication.

Collaborative genome-wide association analysis supports a role for ANK3 and CACNA1C in bipolar disorder

Abstract: To identify susceptibility loci for bipolar disorder, we tested 1.8 million variants in 4,387 cases and 6,209 controls and identified a region of strong association (rs10994336, P = 9.1 x 10(-9)) in ANK3 (ankyrin G). We also found further support for the previously reported CACNA1C (alpha 1C subunit of the L-type voltage-gated calcium channel; combined P = 7.0 x 10(-8), rs1006737). Our results suggest that ion channelopathies may be involved in the pathogenesis of bipolar disorder.
