Summary
Patients with chronic osteomyelitis (CO) exhibit altered immune responses, including higher IgG and lymphocyte counts but impaired cellular immunity. These immune changes do not predict disease severity or prognosis.
Area of Science:
- Immunology
- Infectious Diseases
- Orthopedics
Background:
- Chronic osteomyelitis (CO) involves persistent bone infection.
- Understanding immune system alterations in CO is crucial for management.
- Cellular and humoral immunity may be affected in CO patients.
Purpose of the Study:
- To investigate cellular and humoral immunity in patients with chronic osteomyelitis.
- To compare immune responses in CO patients versus healthy controls.
- To assess the correlation between immune markers and disease characteristics.
Main Methods:
- Studied 19 CO patients and 11 healthy controls.
- Assessed humoral immunity markers (IgG).
- Evaluated cellular immunity (lymphocytes CD3+, CD4+/CD3+ ratio, cutaneous hypersensitivity tests, in vitro blastic stimulation).
Main Results:
- CO patients showed higher IgG, CD3+ lymphocytes, and C-reactive protein (CRP).
- CO patients had a lower CD4+/CD3+ ratio and hypoergic response to skin tests.
- Impaired in vitro blastic stimulation was observed in CO patients.
- Immune changes did not correlate with disease extent, chronicity, or prognosis.
Conclusions:
- Patients with chronic osteomyelitis display significant alterations in both cellular and humoral immunity.
- Current immunological markers do not offer better prediction of bone infection activity than traditional markers like GSR and CRP.
- Further research with sequential immune studies is needed to fully understand the role of immunity in CO.
