Summary

This study evaluates the safety and preliminary efficacy of autologous bone marrow mononuclear cell transplantation combined with rehabilitation in children with neurological sequelae caused by hypoxic-ischemic brain injury or intracranial hemorrhage. Participants in the intervention group will receive autologous bone marrow aspiration, mononuclear cell transplantation via intrathecal route, and rehabilitation, while the control group will receive rehabilitation alone. Outcomes will be compared between groups over follow-up time points.

Detailed description

Neurological sequelae following hypoxic-ischemic brain injury and intracranial hemorrhage in children remain a major clinical challenge with limited effective treatment options. Rehabilitation is the current standard of care but often results in incomplete recovery. Autologous bone marrow mononuclear cell transplantation has emerged as a promising therapeutic approach due to its potential neuroregenerative and neuroprotective effects. This phase II study aims to evaluate the safety and preliminary efficacy of combining autologous bone marrow mononuclear cell transplantation with rehabilitation compared to rehabilitation alone. The study will also contribute to the development of a standardized technical protocol for this intervention.

• Cerebral Palsy Hypoxic-Ischemic Encephalopathy Intracranial Hemorrhage

Interventions

Type	Name	Description
PROCEDURE	Autologous Bone Marrow Mononuclear Cell Transplantation	Autologous bone marrow mononuclear cells (BMMNCs) are collected from the patient's iliac crest under sterile conditions. Bone marrow aspiration is performed under appropriate anesthesia, followed by processing to isolate mononuclear cells using density gradient centrifugation. The prepared BMMNCs are administered via intrathecal injection under aseptic conditions. The dosage of cells is determined based on body weight and viability criteria. Patients are monitored for immediate and delayed adverse events following transplantation. In addition to cell transplantation, participants receive standardized rehabilitation therapy, including physical therapy, occupational therapy, and neurodevelopmental interventions, according to institutional protocols. This combined intervention aims to enhance neurological recovery through both regenerative cellular therapy and functional rehabilitation.
