ABSTRACT

Background: Platelet-rich plasma is now a common medical technique known as regenerative medicine, through power cell activation and differentiation, which produces different growth factors, depending on the cell fraction recovered in the final product both locally and systematically.
Objective: To report the benefit of the systemic application of plasma growth factors in patients with cerebral palsy undergoing specific programs of neurorehabilitation.
Material and Method:: A case-control study done in a population of 50 Caucasian patients under the same program of neurorehabilitation and age range between 5 and 15 years with perinatal cerebral palsy, cognitive impairment, and marked and severe generalized spasticity; we administered an intravenous injection of concentrated leukocyterich plasma (25 cc) in a group of 25 of them. We performed follow-up at 1, 2, 3, 4, 5 and 6 months after the injection. All serum samples for determination were obtained by ELISA technique and Beckman Coulter. Cognitive Barthel scale was used before and after treatment. The determination protocol that was applied before the analysis was performed manually and the self-transfusion was considered suitable for treatment. We determined cellular composition and the plasma levels of factor similar to insulin-1 (IGF-1), platelet-derived growth factor (PDGF), vasculo-endothelial growth factor (VEGF), and transforming growth factor β (TGF-β) before, in the final product obtained in both groups before treatment and at 24 hours and at 1, 2, 3, 4, 5 and 6 months after treatment. Correlations between Cognitive responses in the two population groups throughout the follow-up period were analyzed by Fisher correlation analysis.
Results: No adverse effects were observed in the patients except for a small hematoma in the area channeling venous access. We observed a clear improvement in the cognitive sphere (memory, ability to perform more complex tasks, and acquisition of new skills) clearly higher in the group of patients treated with plasma rich in leukocyte growth factors, significantly statistical difference at 2 months follow-up (p=0.013), maintaining stable from the third month follow-up. Although after 24 hours of treatment in the group of treatment, serum levels of growth factors type VEGF and TGF-β increased 5-6 fold over baseline levels and the group control (p=0.02), it was not correlated with cognitive improvement over six months of clinical follow-up in this group, since virtually objectified plasma levels of growth factors were similar in both groups from the month follow-up study.
Conclusions: We propose that this therapy is useful in these patients to harness the neurostimulative and neuroregenerative power of endogenous growth factors derived from leukocytes, enhancing the effect of neurorehabilitation and shortening cognitive recovery


Key words: leukocyte-rich plasma, cerebral palsy, growth factors, neuronal plasticity, intravenous infusion.
