Abstract:
Osteomyelitis, defined as inflammation of bone, is a highly morbid disease that is most commonly caused by bacterial infection. Infectious osteomyelitis occurs across a spectrum of ages and affects previously healthy individuals as well as individuals with medical comorbidities. Establishment of osteomyelitis typically occurs following one of three general pathological mechanisms, including haematogenous seeding of healthy or injured bone, extension of a contiguous soft tissue infection, or direct inoculation of microorganisms into the bone following trauma. A wide spectrum of microbial pathogens can cause osteomyelitis in these settings. The most common aetiologies share common pathogenic traits such as the propensity to form biofilms, the elaboration of immunoevasive toxins and virulence factors, and the ability to adhere to and invade bone tissue. Challenges in diagnosing, prognosing and treating osteomyelitis remain owing to limitations of conventional cultures, absence of faithful biomarkers, inability to delineate acute versus chronic infection, and therapeutic recalcitrance. Despite prolonged antimicrobial therapy, many individuals with osteomyelitis fail treatment and go on to develop highly morbid complications. Improvements in the management of osteomyelitis will require an ongoing commitment to multidisciplinary clinical care, basic and translational research to uncover pathophysiological mechanisms of disease, and sustained investments in new approaches for the diagnosis, treatment and mitigation of complications.
Insights
Osteomyelitis, a severe bone inflammation often caused by bacteria, presents diagnostic and treatment challenges. Further research and multidisciplinary care are crucial for improving patient outcomes and managing complications.
Area of Science:
- Infectious Diseases
- Orthopedics
- Microbiology
Background:
- Osteomyelitis is a severe bone inflammation, primarily caused by bacterial infections, affecting diverse age groups and health statuses.
- Pathogenesis involves haematogenous spread, contiguous infection extension, or direct inoculation, with pathogens exhibiting biofilm formation and immune evasion.
- Current diagnostic and therapeutic approaches face limitations, including unreliable biomarkers and antimicrobial resistance, leading to treatment failures and complications.
Purpose of the Study:
- To review the pathophysiology, diagnosis, and treatment of osteomyelitis.
- To highlight challenges in managing osteomyelitis and identify areas for future research and clinical improvement.
Main Methods:
- Literature review of osteomyelitis pathogenesis, diagnosis, and treatment.
- Analysis of common microbial virulence factors and host-pathogen interactions.
- Discussion of current clinical management strategies and their limitations.
Main Results:
- Bacterial pathogens causing osteomyelitis share traits like biofilm formation and immunoevasive capabilities.
- Diagnostic and prognostic tools for osteomyelitis remain inadequate, complicating acute versus chronic infection differentiation.
- Treatment recalcitrance and high complication rates persist despite prolonged antimicrobial therapies.
Conclusions:
- Effective osteomyelitis management necessitates a multidisciplinary approach integrating clinical care and research.
- Advancements in understanding disease mechanisms are vital for developing novel diagnostic and therapeutic strategies.
- Sustained investment in research is essential for mitigating osteomyelitis complications and improving patient prognosis.
