For those of us with children on Lithium or depakote it is good to see some solid data is in the works.


Large Controlled Trial of Widely Used Mood Stabilizers Demonstrates Efficacy in Pediatric Bipolar Disorder



Shows Treatment Significantly Effective at Eight Weeks

CINCINNATI, Oct. 26 /PRNewswire/ -- In the largest pediatric study of
its kind on mood stabilizers, scientists from Cincinnati Children's
Hospital Medical Center and two other centers demonstrated that divalproex
sodium (Depakote(R)) has efficacy for significantly improving symptoms of
bipolar I disorder in children and adolescents, according to results
presented today at the annual meeting of the American Academy of Child and
Adolescent Psychiatry in Boston.
Many psychiatric medications prescribed for children and adolescents
have not been indicated by the FDA for pediatric use. Making sure these
drugs are effective and safe has been an important goal of pediatric
psychiatry researchers as well as gaining FDA indications for appropriate
use in children.
"Divalproex and lithium are the most widely used mood stabilizers for
children and adolescents diagnosed with bipolar disorder," said Robert A.
Kowatch, M.D., Ph.D., a child and adolescent psychiatrist specializing in
bipolar and other mood disorders at Cincinnati Children's. "Our study now
proves that these agents definitely work, which may give clinicians and
families peace of mind."
Dr. Kowatch presented the eight-week, acute efficacy results from the
Pediatric Bipolar Collaborative Mood Stabilizer Trial, which also included
a second, 16-week phase. The investigation is the first controlled trial to
test and compare lithium and divalproex versus placebo for six months, the
largest trial of lithium and divalproex to date and first to demonstrate
efficacy for divalproex in children aged 7 to 17 years, diagnosed with
bipolar I disorder, mixed or manic, based on standardized criteria.
Specifically, at the end of an eight-week treatment phase, patients
receiving divalproex significantly decreased their average scores (p<0.01
compared to placebo) on the study's primary outcome measure for manic
symptom severity, the Young Mania Rating Scale (YMRS). Fifty-six percent of
patients in the divalproex group, 41 percent of those in the lithium group
and 30 percent of the placebo group experienced a more than 50 percent
decrease in their YMRS scores (comparisons by treatment group were: p<0.05
for divalproex vs. placebo, p=0.36 for lithium vs. placebo and p=0.10 for
divalproex vs. lithium).
Also, the response rates on the study's other primary outcome measure,
the Clinical Global Impressions Ratings (CGI) - improvement score,
indicated that 54 percent of the divalproex group, 42 percent of the
lithium group and 29 percent of the placebo group improved their CGI scores
by one or two points, (p<0.05 for divalproex vs. placebo, p=0.26 for
lithium vs. placebo and p=0.27 for divalproex vs. lithium).
The National Institute of Mental Health supported the Pediatric Bipolar
Collaborative Mood Stabilizer Trial via a five-year grant. In addition to
Cincinnati Children's, other sites involved were Wisconsin Children's
Hospital and Case Western Reserve University. In the study, investigators
randomly assigned 153 children to receive a placebo, lithium or divalproex.
Neither the investigators nor patients knew to which treatment group the
patients were assigned at the end of the eight week treatment phase. Those
patients who responded to treatment could continue in the double-blind
testing for another 16 weeks.
The classic form of the bipolar illness, also know as bipolar I
disorder, occurs in children 6 to 17 years. The estimated annual number of
for U.S. youths aged 19 years and younger receiving a diagnosis of bipolar
disorder is about 1 percent, based on a 2007 NIH-funded analysis finding
bipolar diagnoses occurring during 1,003 physician office-based visits by
this age group per 100,000 population. Symptoms include severe, explosive
mood swings, euphoria, irritable mood, decreased need for sleep without
daytime fatigue, pressured speech that is difficult to interrupt, racing
thoughts, distractibility that varies with mood, increased goal-directed
activity, hypersexuality and, in some cases, hallucinations. Children with
the illness are at increased risk of attempting suicide. Bipolar disorder,
like epilepsy, tends to be a lifelong mecial condition that can be managed
with medication, psychotherapy and lifestyle changes such as stress
reduction, regular sleep, accommodations at school and avoidance of
caffeine, alcohol and drugs of abuse.
Dr. Kowatch is an internationally known expert for his research in
child and adolescent bipolar disorders. In 2005, he organized and published
the now current national treatment guidelines for bipolar I disorder on
behalf of the Child & Adolescent Bipolar Foundation. The guidelines
appeared in the March 2005 Journal of the American Academy of Child and
Adolescent Psychiatry. The recommendations are based on evidence from
research studies done in children and adults, case reports published in
medical journals, and consensus by a group of experts as to current
clinical practices. Further information about pediatric bipolar disorder
