Allogenic Cord Blood Transfusion in Patients With Autism

Study Overview
=================
Brief Summary
-----------------
Autism is one of those disorders in Autism spectrum disorders (ASD), which characterized by social interaction abnormalities, impaired verbal and non-verbal communication, and repetitive, obsessive behavior, while the therapeutic effect of current treatments remains limited progress. The possible reason for ASD is neural hypoperfusion and immune deregulation. The Human Umbilical Cord Blood Mononuclear Cells (hUCB-MNCs) have been shown to have the ability to modulate the immune response and enhance angiogenesis, suggesting the novel and promising therapeutic strategy. In this study, the safety and efficacy of hUCB-MNCs infusion will be evaluated in patients with Autism.

Detailed Description
-----------------
Autism Spectrum Disorders (ASD) are heterogeneous neuro-developed disorders. Autism is the most common disorder of the diseases characterized by dysfunctions in response social interaction and communication, as well as the presence of repetitive and stereotyped behaviors. Recent reports of a sharp increase in the number of children with autism. The exact etiology of autism remains unclear. Compliance, the definition of effective treatments for autism is particularly difficult. Although it has been understood, it can be a question of immune dysregulation. Examination of the inflammatory cytokines, dysfunction of the immune system and the immune system. The Human Umbilical Cord Blood Mononuclear Cells (hUCB-MNCs) have been shown to have the ability to modulate the immune response and enhance angiogenesis, suggesting the novel and promising therapeutic strategy. The Our study suggest that infusion of cord blood mononuclear cells will affect Autism.

Design Details

Primary Purpose: Treatment
Allocation: Non-Randomized
Intervention Model: Parallel Assignment
Interventional Model Description: This is prospective, non-randomized (open label) with control group study. The total 20 patient will be enrolled in this study. In 10 patient with ASD will be infused with umbilical corb blood. Other 10 patient with ASD will be treated with standard therapy (control group).
Masking: None (Open Label)


Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| A Number of Participants With Non-serious and Serious Adverse Events 24 Hrs Post-transfusion | Safety assessment. The adverse events rate will be assessed in all patients. | 24hrs post transfusion | 
| Autism Treatment Evaluation Checklist (ATEC). | The ATEC is designed to measure changes in the severity of ASD in response to treatment. A total score and 4 subscale scores are reported. Questions in the first 3 subscales are scored using a 0-3 scale (not true/partially true/absolutely true). The 4 subscale, Health/Physical/Behavior, is scored using a 0-4 point scale (Not a problem/Minor problem/Moderate problem/Serious problem). The first subscale, Speech/Language/Communication, contains 14 items where the score ranges from 0-28 points. The Sociability subscale contains 20 items and participants can score from 0-40. The third subscale, Sensory/Cognitive awareness, has 18 items and scores range from 0-36. Finally, the Health/Physical/Behavior subscale contains 25 items and scores range from 0-75. The scores from each subscale are combined in order to calculate a Total Score, which ranges from 0 to179 points. A lower score indicates less severe symptoms of ASD and a higher score correlates with more severe symptoms of ASD. | score at baseline, 1, 2, 6, 12 months | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Cytokine Analysis. | IL1b, IL6, TNF-alpha, IL8, y-IFN measure in patient peripheral blood | score at baseline, 1, 2, 6 months | 
| Immune Status as Determined by Percentage of Peripheral Blood Cells | Peripheral blood flow cytometry cell count for CD3; CD4; CD8; CD19; CD16-56 (%) | score at baseline, 6 month | 
| Immune Status as Determined by Absolute Cell Count of Peripheral Blood Cells | Peripheral blood flow cytometry cell count for CD3; CD4; CD8; CD19; CD16-56 (absolute v.) | score at baseline, 6 month |
