Which Kids Need Antidepressants?
Children With Milder Depression May Get Little Help From Antidepressant Drugs

Jan. 1, 2009 -- Medication helps depressed
kids, but only those whose symptoms are severe enough to warrant treatment with
antidepressants, analysis of clinical trial data
The study is a careful analysis of data from 12 published and unpublished
clinical trials in which newer antidepressant drugs were studied in children
aged 6 to 18 with major
There was a big problem with these studies: A placebo -- fake pills --
helped nearly half of depressed kids get better. Antidepressant drugs did only
a little better, resulting in substantial improvement for 59% of kids vs. 48%
Does this mean the drugs don't work very well? Or is something else going
on? That's what Jeffrey A. Bridge, PhD, of Nationwide Children's Hospital in
Columbus, Ohio, and colleagues tried to find out.
The researchers analyzed all the data collected in the various studies.
They found that kids enrolled in
multicenter clinical trials were much more likely to respond to placebo than
were kids in smaller trials. They also found that kids in larger trials tended
to have less severe depression than kids in smaller trials.
This, they suggest, may mean that antidepressants are most helpful to kids
with at least moderately severe depression. For kids with milder depression,
the drugs' benefits may not outweigh their risks.
"If confirmed, these findings raise questions about the benefit-to-risk
profile of antidepressants in treating depressed pediatric patients with mild
functional impairment," Bridge and colleagues conclude.
Doctors who treat children for depression should pay close attention to this
finding, suggests an editorial by Graham J. Emslie, MD, of the University of
Texas Southwestern Medical Center in Dallas.
The study "emphasizes the importance of a careful and extended
evaluation prior to initiating medication to make sure that the depression is
of sufficient severity to warrant medication treatment," Emslie says.
Emslie makes another major point: The large placebo effect seen in these
studies does not mean there's no such thing as child depression -- nor does it
mean that these children don't need "vigorous treatment."
Bridge and colleagues suggest that kids with milder depression may benefit
more from specialized psychotherapy than from antidepressants as an initial
