Design outcomes

Secondary

MeasureTime frame
Assess possible placebo effect, tolerance GRP infusions and possible adverse effects through monitoring of vital signs during infusions and clinical reassessment in applications ABC scale.;;No adverse effects, changes in vital signs or laboratory abnormalities associated with use of GRP or placebo in any patient.

Primary

MeasureTime frame
Reduction of the characteristic symptoms of autism evaluated across the scale Aberrant Behavior Checklist (ABC)and your subscales Irritability; Lethargy and Social Withdrawal; Stereotyped behavior; Hyperactivity and Noncompliance and Inappropriate Speech with statistically significant difference (P <0.05) between the values after the use of GRP and placebo. ;There was a reduction in scale scores ABC and its subscales after the use of GRP and placebo. Despite this reduction be more prominent with the GRP, particularly in subscales Irritability, Stereotyped behavior and Hyperactivity, there was no statistical difference between the results (p 0.334). After a week of infusion, 5 children had improved more than 25% in the total score of the ABC scale use of GRP and 2 with placebo use, not being statistical difference (p 0.375).
