Estudo com células-tronco do sangue do cordão umbilical mostra promessa para o autismo
A first-of-its-kind double-blinded, estudo cruzado de crianças com autismo que foram tratadas com o próprio sangue do cordão umbilical mostrou que o tratamento é seguro e sugere melhora na socialização.
O estudo, which was published this week in the medical journal Stem Cells Translational Medicine, envolvido 30 children and was conducted by Michael Chez, Médico, the primary investigator who designed the study that was carried out through the Sutter Neuroscience Institute of Sacramento and the Sutter Institute for Medical Research, with research grant funding by Cord Blood Registry® (CBR®). It was the first randomized, double-blinded, placebo-controlled trial performed in the United States to assess the feasibility of treating autistic children by using their own newborn cord blood harvested from their banked umbilical cord.
One of the most exciting outcomes of the study, said Dr. Chez, who is with Sutter Neuroscience Institute, involved successful treatment and blinding of parents and investigators, and safety and tolerability of the treatment in this autistic patient population. Trends toward improvements in areas such as socialization and language were observed.
“The Vineland Adaptive Behavior Scale for Socialization, one of the tests commonly used to measure real-world functional abilities, showed significant improvement after 12 weeks of cord blood treatment over placebo,” Dr.. Chez said. No entanto, when correcting for possible statistical chance when looking at many outcome variables, this observed significance no longer reached significance, probably due to variables such as only 30 patients in this pilot research study.
The study also mirrored a recent non-blinded, open-label Duke University trial that showed similar Vineland Socialization score improvements while also demonstrating that the use of autologous cord blood is safe for the children through intravenous infusions.
Parents contacted about the study were pleased with the improvements they saw in their children.
Jennifer Lundberg of Orlando, Fla., said she knew almost immediately when Hayden received the cord blood infusion as opposed to the saline.
“We had been trying for more than four years to have him potty-trained, and within two weeks he started to self-potty. We never thought this was possible,” ela disse. “He also now has this global understanding of language that he didn’t have before. Por exemplo, I would ask him to open up the air-conditioning vents, and he all of a sudden knew what to do. He doesn’t have the same outbursts that he used to have. It is truly amazing. If we could do it again, we definitely would do it again.”
Another mother who asked not to be identified said her young son also improved. “We saw improvements in his overall development – in his language and social interaction,” ela disse. “It definitely helped.”
CBR, which funded the study, has long been committed to supporting research on the use of cord blood to treat a variety of diseases from cerebral palsy and autism to hearing loss and Type I diabetes.
“The outcome of Dr. Chez’s study, in addition to other recent research advances looking at the use of cord blood for children with autism, are encouraging,” said Heather Brown, vice president of scientific and medical affairs, CBR. “As researchers continue to explore cord blood’s role in regenerative medicine, CBR remains dedicated to investing in clinical trials to better understand this potential and investigating ways we can increase cord blood’s utility.”
