Introduction:

Skin and soft tissue infections (SSTIs) caused by Acinetobacter spp. present unique challenges due to their propensity for antimicrobial resistance and potential for complications. This article explores the clinical manifestations, diagnosis, and treatment strategies for SSTIs attributed to Acinetobacter spp.

Clinical Manifestations:

Localized SSTIs:

• Acinetobacter spp. can cause a range of localized SSTIs, including cellulitis, abscesses, wound infections, and surgical site infections.
• These infections typically present with erythema, swelling, warmth, and tenderness at the affected site, often accompanied by purulent drainage and systemic signs of inflammation.

Necrotizing Fasciitis:

• In severe cases, Acinetobacter spp. SSTIs may progress to necrotizing fasciitis, a life-threatening soft tissue infection characterized by rapid tissue destruction and systemic toxicity.
• Necrotizing fasciitis requires prompt recognition and aggressive surgical debridement in addition to antimicrobial therapy to prevent morbidity and mortality.

Diagnosis:

Clinical Evaluation:

• Diagnosis of Acinetobacter spp. SSTIs begins with a thorough clinical assessment, including a detailed medical history, physical examination, and evaluation of the extent and severity of the infection.
• Special attention should be paid to risk factors for multidrug-resistant organisms, recent hospitalizations, surgical procedures, or exposure to healthcare settings.

Microbiological Investigations:

• Microbiological sampling of wound specimens or purulent drainage is essential for identifying the causative pathogen and determining antimicrobial susceptibility.
• Cultures should be obtained before initiating empirical antibiotic therapy to guide targeted treatment and surveillance for antimicrobial resistance.

Treatment Strategies:

Empirical Therapy:

• Empirical antibiotic therapy for suspected Acinetobacter spp. SSTIs should provide broad-spectrum coverage against Gram-negative bacteria, including multidrug-resistant strains.
• Initial regimens may include combination therapy with agents such as carbapenems, polymyxins, or tigecycline to optimize coverage and minimize the risk of treatment failure.

Tailored Therapy:

• Tailored antibiotic therapy based on culture and susceptibility results is crucial for optimizing treatment efficacy and minimizing the emergence of resistance.
• Adjustments to antimicrobial regimens may be necessary based on local resistance patterns, patient response, and clinical course.

Adjunctive Measures:

Surgical Debridement:

• Surgical intervention, such as incision and drainage or surgical debridement, is often necessary for managing complex or deep-seated SSTIs, particularly in cases of necrotizing fasciitis.
• Surgical procedures aim to remove infected and necrotic tissue, improve wound healing, and reduce the bacterial burden.

Wound Care:

• Optimal wound care practices, including regular cleansing, debridement of devitalized tissue, and appropriate dressing selection, promote healing and prevent secondary infections.
• Close monitoring of wound progress, signs of infection, and response to therapy is essential for guiding ongoing management.

Conclusion:

Skin and soft tissue infections caused by Acinetobacter spp. require a comprehensive approach encompassing clinical evaluation, microbiological diagnosis, and targeted antimicrobial therapy. By implementing appropriate treatment strategies, including empirical and tailored antibiotic therapy, surgical intervention, and adjunctive measures, healthcare providers can effectively manage Acinetobacter spp. SSTIs and optimize patient outcomes.
