Anemia and serum protein deficiencies in patients with traumatic spinal cord injury.

This study was conducted to further investigate the natural history of the anemia, hypoproteinemia and hypoalbuminemia commonly observed in patients with traumatic spinal cord injury (SCI). Blood samples were taken from 46 traumatic SCI patients at the time of initial admission to an acute rehabilitation hospital and again approximately one year later during a routine follow-up appointment. At initial admission, 65 percent of patients were anemic (hemoglobin < 13.0 g/dl), 86.7 percent were hypoalbuminemic (albumin < 3.2 g/dl) and 48.9 percent were hypoproteinemic (total protein < 6.5 g/dl). Deficiencies were most commonly observed in tetraplegics and in patients with complete injuries. At the time of follow-up, 6.8 percent of patients were anemic, 2.2 percent demonstrated abnormally low serum protein concentrations and a significant (p = 0.01) decrease in the incidence of each deficiency was observed. Our findings suggest that anemia and decreased serum protein concentrations, while commonly observed in the acute SCI population, are much less frequently encountered in the more chronically injured. If noted in the chronic SCI patient, these deficiencies should alert clinicians to the likelihood of a concurrent process.
