Update on treatment options for spinal brucellosis

Area of Science:

• Infectious Diseases
• Orthopedics
• Pharmacology

Background:

• Spinal brucellosis is a serious infection requiring effective treatment.
• Understanding differences between complicated and uncomplicated forms is crucial for patient outcomes.
• Optimal antibiotic regimens and therapy duration need further evaluation.

Purpose of the Study:

• To evaluate antibiotic efficacy and duration for spinal brucellosis.
• To compare clinical features and treatment responses in complicated versus uncomplicated spinal brucellosis.
• To identify factors influencing treatment outcomes in spinal brucellosis.

Main Methods:

• Multicentre, retrospective, comparative study of 293 spinal brucellosis patients.
• Statistical analysis comparing complicated (78 cases) and uncomplicated spinal brucellosis.
• Evaluation of five common antibiotic combination regimens, primarily doxycycline, rifampicin, and aminoglycosides.

Main Results:

• Complicated spinal brucellosis showed more acute symptoms, higher inflammatory markers, and thoracic spine involvement.
• Abscess formation (paravertebral, prevertebral, epidural, psoas) and radiculitis were noted in complicated cases.
• No significant therapeutic differences were found between antibiotic regimens; however, complicated cases received longer treatment durations.

Conclusions:

• Early identification of complicated spinal brucellosis is essential for preventing severe outcomes.
• Prolonged antimicrobial therapy is particularly recommended for complicated spinal brucellosis.
• Standard antibiotic regimens showed similar efficacy, but duration adjustments are critical based on disease complexity.
