Evaluation of Autologous Mesenchymal Stem Cell Transplantation in Chronic Spinal Cord Injury: a Pilot Study

This is a pilot, open, phase I study, in a prospective cohort. The study population will consist of 5 patients who had spinal cord injury for at least 6 months, with complete paraplegia.

A practitioner, a neurosurgeon and a nurse will review the medical records of patients to determine the presence / absence of inclusion / exclusion criteria. If the patient is a potential candidate for the study, an interview will be scheduled with the patient to review and confirm his/her eligibility. If the clinical eligibility is confirmed, the patient will undergo psychosocial evaluation to determine the degree of emotional equilibrium and conditions for participation in the study.

Patients will undergo a series of clinical and neurological evaluations and will also be submitted to the following procedures:

• Cell blood count;
• Biochemical analysis (measurement of electrolytes - sodium, potassium, magnesium);
• Renal function tests (urea and creatinine);
• Liver function tests;
• Coagulation profile;
• Metabolic profile (glucose, total cholesterol and fractions);
• Urine summary and culture;
• Serology required for blood transfusion and marrow transplant in Brasil;
• Electrocardiogram;
• Chest X-Ray, X-ray of knees;
• Bone densitometry;
• Urodynamic studies;
• Somatosensory evoked potential;
• Computed tomography of thoracic and lumbar spine;
• MRI of the thoracic and lumbar spine.

Also as part of the preoperative evaluation, the patients will respond to questions from the SF (Short Form) -36 questionnaire (for assessment of quality of life) and the questionnaires for the assessment of neuropathic pain.

Clinical follow-up will be kept for patients who suspend their participation in the study for any adverse event and / or laboratory abnormality, or for the patient's own desire, following insurance protocols. In addition to the clinical and surgical follow-up, specific medical care will be offered to patients who experience adverse events, until stabilization of the patient, even if the target date for completion of the study has been exceeded.

The candidates included in the study will be asked to voluntarily participate and give their informed written consent. Patients will be recruited for a minimum period of 06 months to follow up with additional laboratory and clinical examinations.
