Summary
This study differentiates tuberculous, brucellar, and pyogenic vertebral osteomyelitis (VO) by distinct clinical, lab, and imaging features. Understanding these differences aids in diagnosing spinal infections like VO.
Area of Science:
- Infectious Diseases
- Orthopedics
- Radiology
Background:
- Vertebral osteomyelitis (VO) is a growing spinal infection impacting diverse populations.
- Differential diagnosis is challenging due to multiple causative pathogens, including tuberculosis and brucellosis.
- Timely and accurate diagnosis is crucial for effective patient management.
Purpose of the Study:
- To compare the clinical, laboratory, and radiological characteristics of tuberculous (TVO), brucellar (BVO), and pyogenic (PVO) vertebral osteomyelitis.
- To identify key features that distinguish between these different types of VO.
Main Methods:
- A single-center, retrospective, observational study was conducted from 2019 to 2022.
- 319 patients diagnosed with VO were analyzed, categorized into TVO, BVO, and PVO groups.
- Data collected included demographics, clinical presentation, laboratory results, radiological findings, and microbiological data.
Main Results:
- TVO patients showed longer diagnosis times, higher rates of fever, weight loss, and specific lab ratios (MLR, PLR), with frequent thoracic involvement.
- BVO was more common in males, with lower back pain as a primary symptom.
- PVO patients had higher rates of prior spinal surgery, diabetes, elevated white blood cells, and neutrophils, alongside high culture positivity.
Conclusions:
- Distinct clinical, laboratory, and radiological profiles differentiate TVO, BVO, and PVO.
- These findings support improved diagnostic strategies for vertebral osteomyelitis based on specific patient characteristics.
