在google上搜索到的一篇有关D-cycloserine 治疗自闭症的文章,David Posey博士在全美第50届儿童和成人心理学年会上的大会交流(2003.10),可惜我至今未在PUBMED上未检索到该课题的论文,准备这几天去EMAIL问问Posey博士,该课题究竟结果如何,有无应用潜力。
AACAP: D-cycloserine Shows Promise in Treatment of Autistic Disorder
By Jerry Ingram
MIAMI BEACH, FL -- October 21, 2003 -- Symptoms of social withdrawal seen in autistic children might improve with D-cycloserine treatment, according to preliminary research presented here on October 18th at the 50th Anniversary Meeting of the American Academy of Child and Adolescent Psychiatry.
"There is a preliminary sense that D-cycloserine has some efficacy for social withdrawal in autism. We're following it up with a controlled study," stated David Posey, MD, lead researcher, assistant professor of psychiatry, Indiana University, Indianapolis, Indiana.
For this pilot study, investigators conducted a 2-week, single blind, placebo lead-in phase study of 10 drug-free patients with autistic disorder. Patients received three different doses of D-cycloserine during each of three 2-week periods. They were evaluated using Clinical Global Impressions (CGI) scale, Aberrant Behavior Checklist (ABC), the Social Responsiveness Scale, and the Children's Yale-Brown Obsessive Compulsive Scale.
Researchers found that 70% of 10 children had a CGI global improvement rating of "much improved" or "very much improved" while taking at least one dose level of D-cycloserine. The mean optimal dose for all subjects was 1.8 mg/kg/day (modal dose, 50 mg/day), they said.
Fifty percent of the patients were "classified as sustained," showing improvement in social withdrawal, amount and spontaneity of language, and repetitive behavior. The most noteworthy improvement was in the Lethargy subscales of the Aberrant Behavior Checklist, with a 57% decrease in symptom severity, Dr. Posey reported.
He also noted that D-cycloserine was well tolerated in all patients with the dose range used in this study. However, further controlled studies are necessary, he noted.
