Diabetes-Related Foot Infections: Diagnosis and Treatment

Area of Science:

• Infectious Diseases
• Endocrinology
• Podiatry

Background:

• Diabetes-related foot infections complicate approximately 40% of diabetic foot ulcers, leading to significant morbidity.
• Risk factors include foot ulcers, uncontrolled diabetes, poor perfusion, and comorbidities.

Purpose of the Study:

• To outline the evaluation, diagnosis, and management of diabetes-related foot infections and osteomyelitis.
• To emphasize appropriate diagnostic methods and antibiotic strategies.

Main Methods:

• Clinical evaluation of risk factors and infection indicators (erythema, warmth, drainage).
• Diagnostic imaging (radiography, MRI, CT) for suspected osteomyelitis.
• Deep wound or bone cultures for pathogen identification; avoidance of superficial cultures.

Main Results:

• Common pathogens include Staphylococcus aureus and Streptococcus agalactiae; polymicrobial infections are frequent.
• Treatment involves antibiotics tailored to local resistance, severity, and patient factors.
• Mild/moderate infections may use oral antibiotics; severe cases require IV antibiotics.

Conclusions:

• Effective management involves prompt diagnosis, appropriate culturing, and targeted antibiotic therapy.
• Severe or persistent infections may necessitate surgical intervention and specialized wound care.
• Systematic assessment and comorbidity management are key for secondary prevention.
