NCT ID: NCT00001359 Completed - Clinical trials for Obsessive Compulsive Disorder

Preventive Measures for Childhood-Onset Obsessive-Compulsive Disorder and Tic Disorders (PANDAS Subgroup)

Start date: April 1993
Phase: Phase 2
Study type: Interventional

A subgroup of patients with childhood-onset obsessive-compulsive disorder (OCD) and/or tic disorders has been identified who share a common clinical course characterized by dramatic onset and symptom exacerbations following group A beta-hemolytic streptococcal (GABHS) infections. This subgroup is designated by the acronym PANDAS (Pediatric Autoimmune Neuropsychiatric Disorders Associated with Streptococcal infections). There are five clinical characteristics that define the PANDAS subgroup: presence of OCD and/or tic disorder; prepubertal symptom onset; sudden onset or abrupt exacerbations (relapsing-remitting course); association with neurological abnormalities (presence of adventitious movements or motoric hyperactivity during exacerbations); and temporal association between symptom exacerbations and GABHS infections. In this subgroup, periodic exacerbations appear to be triggered by GABHS infections in a manner similar to that of Sydenham's chorea, the neurological variant of rheumatic fever. Rheumatic fever is a disorder with a presumed post-streptococcal autoimmune etiology. The streptococcal pathogenesis of rheumatic fever is supported by studies that have demonstrated the effectiveness of penicillin prophylaxis in preventing recurrences of this illness. A trial of penicillin prophylaxis in the PANDAS subgroup demonstrated that penicillin was not superior to placebo as prophylaxis against GABHS infections in these children, but this outcome was felt to be secondary to non-compliance with treatment, and there was no decrease in the number of neuropsychiatric symptom exacerbations in this group. In a study comparing azithromycin and penicillin, both drugs were completely effective in preventing streptococcal infections - there were no documented titer elevations during the year-long study period for children taking either penicillin or azithromycin. Comparable reductions in the severity of tics and obsessive-compulsive symptoms were also observed. Thus, penicillin was not performing as an "active placebo" as originally postulated, but rather provided effective prophylaxis against Group A beta-hemolytic streptococcal. Both azithromycin and penicillin appear to be effective in eliminating GABHS infections, and reducing neuropsychiatric symptom severity; thus, between-group differences are negligible. Since increasing the "n" to demonstrate superiority of one prophylactic agent over another would be impractical, we have amended the study design to address two issues: 1. To determine if antibiotics prophylaxis against GABHS infections is superior to placebo in prolonging periods of remission among children in the PANDAS subgroup. 2. To determine if antibiotics prophylaxis against GABHS infections is superior to placebo in improving overall symptom severity for obsessive-compulsive symptoms and tics among children in the PANDAS subgroup. Because penicillin has a narrower therapeutic index and is less expensive than azithromycin, it is the preferable prophylactic agent. Further, penicillin (250 mg orally twice a day) has a long history of providing safe and effective prophylaxis for rheumatic fever and is the first line oral therapy recommended by the American Heart Association. Thus, penicillin has been chosen as the prophylactic antibiotic in the present study. Blister packs are used to increase compliance and to allow for easier documentation of missed doses.

NCT ID: NCT00000389 Completed - Anxiety Disorders Clinical Trials

Treatment for Anxiety in Children

Start date: October 1996
Phase: Phase 3
Study type: Interventional

The purpose of this study is to see if it is effective to treat children with anxiety disorders with fluvoxamine. Fluvoxamine has been successfully used to treat obsessive-compulsive disorder (OCD) in adults and children. Anxiety disorders other than OCD, such as generalized anxiety disorder, social phobia, or separation anxiety, are very common in youth and are not always responsive to behavioral therapies alone. These disorders may respond to fluvoxamine. A child will be evaluated for 3 weeks before he/she is assigned randomly (like tossing a coin) to receive either fluvoxamine or an inactive placebo for 8 weeks. After this double-blind phase (neither the child/parents nor the doctor know which treatment is being given), the child will have the option of continuing treatment during a 4-month open-label extension period (both the child/parents and the doctor know which the child is receiving). A child may be eligible for this study if he/she: Is 6 to 17 years old and has been diagnosed with an anxiety disorder (i.e., generalized anxiety disorder, social phobia, or separation anxiety).

NCT ID: NCT00000386 Completed - Clinical trials for Obsessive-Compulsive Disorder

Behavior Therapy for Children and Adolescents With Obsessive-Compulsive Disorder (OCD)

Start date: December 1998
Phase: Phase 3
Study type: Interventional

The purpose of this study is to evaluate a behavioral treatment program for children and adolescents with OCD and their families. Exposure and Response Prevention (ERP) behavior therapy, in which the patient is gradually exposed to the object or situation that causes anxiety and is taught to refrain from responding in a compulsive manner, is combined with family counseling (Family Treatment Program). This treatment will be compared to Relaxation Training (RT). OCD is a long-term, often disabling disorder that can cause significant family disruption. ERP is a promising treatment for children with OCD, and it is thought that family participation (through the Family Treatment Program) may be a helpful addition. RT is a common treatment for anxiety. Patients are assigned randomly (like tossing a coin) to receive either the ERP/Family Treatment Program or RT. Both treatments will be delivered over 12 90-minute outpatient sessions to youngsters and their families. All participants (patients and family members) will be assessed for treatment response each month during treatment, after treatment is finished, and then at 2 follow-up visits over the following 6 months. A child/adolescent may be eligible for this study if he/she: Has obsessive-compulsive disorder (OCD), is medication-free, and is 8 to 17 years old.

NCT ID: NCT00000384 Completed - Clinical trials for Obsessive-Compulsive Disorder

Treatment of Obsessive-Compulsive Disorder (OCD) in Children

Start date: May 1997
Phase: Phase 3
Study type: Interventional

The purpose of this study is to compare 3 treatments for children with OCD: medication (sertraline, SER) alone vs OCD-specific therapy (Cognitive Behavior Therapy, CBT) vs medication plus therapy. Some patients will receive an inactive placebo (PBO) instead of medication and/or Educational Support (ES, non-psychological treatment) instead of therapy. One in 200 children suffer from OCD, but few receive appropriate treatment. Both CBT and medication seem to be effective, but their effectiveness, alone and in combination, has not been evaluated. There are 2 phases to this trial. In Phase I the child will receive 1 of the following 6 treatments for 12 weeks: 1) SER alone; 2) pill PBO alone; 3) CBT alone; 4) SER plus CBT; 5) SER plus ES; 6) pill PBO plus ES. If the child responds to treatment, he/she will go on to Phase II in which the treatment will be slowly reduced, then stopped (discontinued), over time to test the treatment's durability. The child will be evaluated at Weeks 1, 4, 8, 12 (Phase I treatment), and Weeks 16, 20, 24, and 28 (Phase II discontinuation) to see how effective and durable the treatment is in treating your child's OCD. A child may be eligible for this study if he/she: Has obsessive-compulsive disorder (OCD) and is 8 - 16 years old.

NCT ID: NCT00000373 Completed - Clinical trials for Obsessive-Compulsive Disorder

Treatment of Obsessive-Compulsive Disorder

Start date: September 1992
Phase: Phase 4
Study type: Interventional

The purpose of this study is to find the best treatment for Tourette's Syndrome (TS)-spectrum obsessive-compulsive disorder (OCD), which includes symptoms of TS, e.g., repeated and involuntary body movements (tics). There are 2 parts to this study: In Part 1, patients are placed into 1 of 2 groups based on type of OCD, determined by medical history and family member interviews. In Part 2, patients are treated with fluvoxamine (FVX) for 8 weeks. If patients do not respond to FVX alone, either haloperidol or an inactive placebo will be added to the FVX regimen; patients will take this drug combination for 4 weeks. Patients will be monitored throughout the trial.
