Summary
Patients with bedsores from spinal cord trauma exhibit immune system dysfunction, including altered immunoglobulin levels and reduced neutrophil activity. This immune deficiency contributes to chronic, non-healing wounds.
Area of Science:
- Immunology
- Wound Healing
- Traumatology
Background:
- Bedsores (pressure ulcers) are common in spinal cord injury patients.
- Impaired immune function is suspected in the pathogenesis of chronic wounds.
Purpose of the Study:
- To investigate immune system alterations in patients with bedsores secondary to spinal cord trauma.
- To correlate immune dysfunction with the chronic nature of these wounds.
Main Methods:
- Analysis of blood and tissue biopsies from 36 patients with bedsores.
- Measurement of immunoglobulin (IgA, IgM, IgG) levels.
- Assessment of circulating immune complexes (CIC) and neutrophil leukocyte chemotactic activity.
Main Results:
- Significant alterations in IgA, IgM, and IgG levels were observed.
- Increased CIC levels and decreased neutrophil chemotactic activity were found.
- Evidence of immunoglobulin and CIC deposition in granulation tissue vessels.
Conclusions:
- Patients with bedsores due to spinal cord trauma develop immune system dysfunction and secondary immune deficiency.
- Chronic vasculitis, hypoxia, and impaired fibroblast function contribute to non-healing wounds.
- Defective collagen synthesis (type III) hinders skin maturation and wound closure.
