Soft Tissue Infections in Diabetic Patients

Area of Science:

• Infectious Diseases
• Endocrinology
• Surgical Pathology

Background:

• Diabetes mellitus impairs immune mechanisms, increasing susceptibility to severe infections.
• Hyperglycemia, micro/macroangiopathy, and neuropathy contribute to altered neutrophil function and reduced antibacterial defenses.
• Soft tissue infections in diabetics demand a complex medico-surgical approach, integrating aggressive surgery with metabolic control and antibiotics.

Purpose of the Study:

• To analyze the characteristics and management of soft tissue infections in diabetic patients.
• To identify common pathogen profiles, comorbidities, and treatment outcomes.
• To highlight the need for a multidisciplinary approach in managing these infections.

Main Methods:

• A retrospective descriptive study of 150 diabetic patients with soft tissue infections (excluding diabetic foot).
• Data collected included lesion type, localization, microbial flora, comorbidities, biological parameters, and treatment strategies.
• Analysis focused on surgical interventions, antibiotic therapy, and postoperative evolution.

Main Results:

• Lower limb infections were most frequent (54%), predominantly in males aged 60-69 with Type II diabetes (93%).
• Common comorbidities included cardiovascular disease and obesity. Staphylococcus aureus was the most frequent pathogen.
• Treatment involved empirical and targeted antibiotics (cephalosporins, carbapenems) and surgical debridement/necrectomy; some cases required amputation.

Conclusions:

• Soft tissue infections in diabetics are heterogeneous, requiring thorough clinical assessment.
• Multidisciplinary management with rapid, serial surgical interventions is essential to combat aggressive microbial infections.
• Prompt, individualized therapeutic decisions and close patient monitoring are key to favorable postoperative outcomes.
