Summary
Human immunodeficiency virus (HIV) does not alter spinal infection presentation or causative organisms. Neurologic outcomes in patients with spinal infections depend on initial status, not HIV status.
Area of Science:
- Infectious Diseases
- Neurology
- Spinal Surgery
Background:
- Spinal infections, including epidural abscesses and vertebral osteomyelitis, pose significant clinical challenges.
- The role of human immunodeficiency virus (HIV) in modifying the presentation and outcomes of spinal infections requires further elucidation.
Purpose of the Study:
- To investigate the impact of HIV on the clinical features, microbial etiology, and neurologic outcomes of patients with spinal infections.
- To compare spinal infection characteristics and patient outcomes between HIV-positive and HIV-negative individuals.
Main Methods:
- Retrospective review of 32 patients with spinal infections treated over 42 months.
- Diagnosis confirmed via surgical procedures and percutaneous biopsies.
- Microbial identification through intraoperative and blood cultures.
Main Results:
- Staphylococcus aureus was the predominant organism in both HIV-positive (13 patients) and HIV-negative groups.
- Clinical presentations (pain, neurologic abnormalities) and causative organisms were similar across both groups.
- Neurologic outcomes were primarily determined by the patient's neurologic status at the time of treatment.
Conclusions:
- Concurrent HIV infection does not significantly alter the clinical presentation or microbial profile of spinal infections.
- Neurologic recovery in spinal infection patients is independent of HIV status, emphasizing the importance of baseline neurologic condition.
