What is the treatment for Methicillin-resistant Staphylococcus aureus (MRSA) infection of the face?

From the Guidelines

Treatment for MRSA infection of the face typically requires prompt medical attention, incision and drainage of any abscesses, and antibiotic therapy with oral antibiotics such as clindamycin, trimethoprim-sulfamethoxazole, or a tetracycline. The choice of antibiotic should be based on the severity of the infection and the patient's clinical response. According to the clinical practice guidelines by the Infectious Diseases Society of America 1, for outpatients with purulent cellulitis, empirical therapy for CA-MRSA is recommended pending culture results.

Key Considerations

• Incision and drainage is the primary treatment for cutaneous abscesses, including those on the face, and is likely to be adequate for simple abscesses or boils 1.
• Antibiotic therapy is recommended for abscesses associated with severe or extensive disease, rapid progression, signs and symptoms of systemic illness, or abscesses in areas difficult to drain, such as the face 1.
• Empirical therapy for CA-MRSA in outpatients with SSTI can include oral antibiotics such as clindamycin, trimethoprim-sulfamethoxazole, or a tetracycline 1.
• For hospitalized patients with complicated SSTI, empirical therapy for MRSA should be considered pending culture data, and options include intravenous vancomycin, linezolid, daptomycin, telavancin, or clindamycin 1.

Treatment Options

• Oral antibiotics: clindamycin (300-450 mg three times daily for 7-10 days), trimethoprim-sulfamethoxazole (1-2 tablets twice daily for 7-10 days), or doxycycline (100 mg twice daily for 7-10 days) 1.
• Intravenous antibiotics: vancomycin, linezolid, daptomycin, or telavancin for severe infections or hospitalized patients 1.
• Topical treatments: mupirocin ointment applied to the affected area three times daily and washing with chlorhexidine soap.
• Warm compresses applied to the area for 15 minutes, 3-4 times daily, can help improve blood flow and healing.

Prevention and Hygiene

• Personal hygiene measures like frequent hand washing, not sharing personal items, and keeping wounds covered are essential to prevent spreading the infection to others.
• Completing the full course of antibiotics even if symptoms improve quickly is crucial to prevent recurrence and antibiotic resistance.

From the FDA Drug Label

The cure rates by pathogen for microbiologically evaluable patients are presented in Table 18. Table 18 Cure Rates at the Test-of-Cure Visit for Microbiologically Evaluable Adult Patients with Complicated Skin and Skin Structure Infections Pathogen Cured ZYVOX n/N (%) Oxacillin/Dicloxacillinn/N (%) Staphylococcus aureus 73/83 (88) 72/84 (86) Methicillin-resistant S aureus 2/3 (67) 0/0 (-)

The treatment for Methicillin-resistant Staphylococcus aureus (MRSA) infection of the face is linezolid (ZYVOX), with a cure rate of 67% in microbiologically evaluable patients with MRSA complicated skin and skin structure infections 2.

• Key points:
  • Linezolid is effective against MRSA infections
  • Cure rate is 67% in microbiologically evaluable patients
  • Linezolid can be used to treat complicated skin and skin structure infections, including those caused by MRSA
• Note: The cure rate for MRSA skin and skin structure infection was also 79% for linezolid-treated patients in a separate study 2.

From the Research

Treatment Options for MRSA Infections of the Face

• The treatment of MRSA infections, including those of the face, can be challenging due to the emergence of new resistance mechanisms 3.
• Tedizolid, a next-generation oxazolidinone, has shown promising results in treating skin and soft tissue infections caused by MRSA, with higher in vitro activity compared to other antimicrobials such as vancomycin and linezolid 3, 4.
• Studies have demonstrated that tedizolid has several potential advantages over linezolid, including once-daily dosing, shorter duration of therapy, and increased tolerability 4.
• Other treatment options for MRSA infections include vancomycin, linezolid, and daptomycin, with linezolid showing superiority in clinical and microbiological success in some studies 5.
• The choice of treatment may depend on various factors, including the severity of the infection, the patient's medical history, and the presence of any underlying conditions 6.

Efficacy of Tedizolid Against MRSA

• Tedizolid has demonstrated potent activity against MRSA, including isolates with reduced susceptibility to vancomycin, daptomycin, or linezolid 7.
• Studies have shown that tedizolid has lower MIC values compared to linezolid, indicating its potential as a viable treatment option for MRSA infections 3, 7.
• Tedizolid's efficacy against MRSA has been evaluated in various studies, with results suggesting its potential as a promising alternative for the treatment of infections caused by MRSA 3, 4.

Considerations for Treatment

• The treatment of MRSA infections requires careful consideration of various factors, including the patient's medical history, the severity of the infection, and the presence of any underlying conditions 6.
• The choice of treatment may also depend on the availability of antibiotics, their cost, and their potential side effects 4, 5.
• Further studies are needed to establish a preferred regimen for the treatment of MRSA infections and to determine the most effective treatment strategies for different patient populations 6, 5.
