PROSPECTIVE SINGLE CENTER ANALYSIS OF OUTCOME STEM CELLS TRANSPLANTS IN PATIENTS WITH CEREBRAL PALSY

Abstract

Aim: To evaluate efficacy and safety of autologous bone marrow-derived mononuclear stem cell transplantation intrathecal in children with cerebral palsy. Materials and Methods: 35 children have levels I-V cerebral palsy aged 8-months to 8-years-old were enrolled from September (2021-2022) at Iraqi private hospital. Gross Motor Function was assessed by a pediatrician and neurologist specialist, 5 mcg/kg/day of G-CSF subcutaneous single injection daily for three consecutive days. Bone marrow harvested from posterior iliac crest under light general anesthesia. Bone marrow mononuclear cells (BMMNCs) separation was performed using density gradient centrifugation with Ficoll, the cell viability checked by propidium iodide dye in a TALI machine (Invitrogen) in average 98%. The viable BMMNCs injected intrathecal in L4–L5 over a period of 5–10 min. Results: Males accounted for 57.14% (20/35) while female 42.86% (15/35), and main neurological symptoms included spastic disorder spastic disorder (quadriplegia 24 (68.6), tetraplegia 2 (5.7), diplegia 5 (14.28), hemiplegia4 (11.42)). Gross Motor Function Classification System and Gross Motor Function Measure-66 (GMFM-66) showed II 10 (28.58), III 11(31.42) and IV 14 (40). On mean follow-up of 3 months post-stem cell transplant improvement was observed in 80% cases. The improvement showed in gross motor function (6/8) p=0.01, and speech (2/4) p=0.04, neck holding (5/5) p=0.0003, sitting balance (4/4) p=0.04, postural tone (5/5) p=0.0003, as well as significant reduction in seizure frequency (2/3) p=0.04 and improvement in cognition (6/7) p=0.01 were observed. Conclusion: Stem cell therapy for cerebral palsy shows a significant positive effect on the gross motor function, without long adverse effects.
