This will be a 12-week open-label pilot treatment study for children and adolescents (ages 6-17) who meet DSM-IV criteria for bipolar disorder (BPD) and obsessive-compulsive disorder (OCD) who are adequately mood stabilized on a stable regimen based on standard clinical care. Specific hypotheses are as follows:

Hypothesis 1: Children and adolescents with comorbid OCD and BPD who have achieved adequate mood stabilization using a naturalistic clinical practice approach, will benefit from an FDA-approved selective seratonin reuptake inhibitor (SSRI) on their OCD symptoms in a clinically meaningful way without exacerbation of bipolar symptoms.

Condition Intervention Phase

Primary Outcome Measures:
  • Children's Yale-Brown Obsessive Compulsive Scale (CY-BOCS) [ Time Frame: weekly ]
    This sale measures impairment on 5 items relating to Obsessions from 0 (none) to 4 (extreme) and 5 item relating to Compulsions from 0 (none) to 4 (extreme). These scores are totaled for a range of 0 (least impaired) to 40 (most impaired).

Secondary Outcome Measures:
  • Young Mania Rating Scale (YMRS) [ Time Frame: weekly ]
    This scale measures mania symptoms in children and adolescents using 11 items rated from 0 (least severe) to 4 (most severe), although 4 items are rated from 0-8. The minimum (least severe) possible score is 0, and the maximum (most severe) possible score is 60.

Enrollment: 13
Study Start Date: December 2005
Study Completion Date: September 2010
Primary Completion Date: September 2010 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Fluoxetine Drug: fluoxetine
capsules, dose range of 10mgQD - 60mgQD, given daily for 12 weeks
Other Name: Prozac

Detailed Description:

As no systemic data is available regarding the efficacy and safety of selective serotonin reuptake inhibitors (SSRI) in the treatment of OCD+BPD children, it calls for a preliminary open pilot treatment study to explore these issues as a logical first step that could lead to systematic randomized controlled trials in the future. SSRI's are the first line and most commonly used anti-OCD agents. It remains unknown, which of the standard SSRIs is least activating for youth with BPD. Fluoxetine along with fluvoxamine and sertraline are FDA approved for the treatment of OCD in children. Fluoxetine remains the most extensively studied SSRI in children. We will test the safety and efficacy of fluoxetine in children and adolescents with BPD and OCD.

The proposed study includes 1.) the use of a 12-week design to document the response rate and 2.) careful assessment of safety and tolerability

  • Subject must be able to participate in mandatory blood draws.
  • Subject must be able to swallow pills.
  • Subjects with comorbid ADHD, ODD, CD, or other anxiety disorders will be allowed to participate in the study provided they do not meet any exclusionary criteria.
