OBJECTIVE: To evaluate phagocytic activity and neutrophil oxidative burst functions in patients with spinal cord injury (SCI) since alterations in neutrophil metabolic activity can be one of the causes of immune mechanism damage contributing to repeated bacterial infections. DESIGN: A controlled and cross-sectional study. SETTING: Departments of Physical Medicine & Rehabilitation and Immunology. PARTICIPANTS: A total of 34 patients with SCI and 28 healthy controls. INTERVENTIONS: Phagocytosis and oxidative burst in whole-blood neutrophils were assessed by flow cytometry. Percentage of phagocytizing cells after in vitro incubation with E. coli, phagocytic activity (mean intensity of fluorescence, MIF) and the percentage of neutrophil oxidative burst, and MIF value of production of reactive oxygen intermediates (ROIs) were analyzed. In addition, clinical assessment including the level of injury, ASIA scores, and functional status were carried out. MAIN OUTCOME MEASURES: Not Applicable. RESULTS: Although the percentage of E. coli phagocytizing neutrophils was not different between groups, the MIF value of absorbed E. coli was significantly lower in the patients with SCI vs controls (p<0.05). The MIF value of ROI production by neutrophils with both stimulator of phorbol 12-myristate 13-acetate (PMA) and E.Coli was significantly higher in patients with SCI (p<0.05). CONCLUSION: In patients with SCI, decreased phagocytic activity of neutrophils may be a result of a regulatory mechanism to minimize the deleterious effects of increased neutrophil burst activity.
