From the Guidelines
Treatment for MRSA empyema should involve a combination of drainage procedures and antibiotic therapy, with vancomycin or linezolid being recommended options, as stated in the guidelines by the Infectious Diseases Society of America 1. When managing MRSA empyema, it is crucial to consider the severity of the infection and the need for both antimicrobial coverage and drainage of the infected pleural fluid.
- The primary goal is to effectively treat the infection while minimizing morbidity and mortality.
- Drainage procedures, such as chest tube placement or surgical intervention like video-assisted thoracoscopic surgery (VATS) or thoracotomy with decortication, are essential for removing the infected fluid and allowing the antibiotics to penetrate the affected area more effectively.
- For antibiotic therapy, vancomycin (A-II) or linezolid 600 mg PO/IV twice daily (A-II) are recommended options, with the choice depending on the severity of the infection, patient tolerance, and susceptibility of the MRSA strain, as per the guidelines 1.
- The treatment duration typically ranges from 7-21 days, depending on the extent of the infection, and may require adjustment based on clinical response and follow-up imaging.
- Supportive care, including pain management, respiratory support, and nutritional support, is also vital for optimal recovery and improving the patient's quality of life.
- Regular monitoring of clinical response, inflammatory markers, and follow-up imaging is necessary to guide the duration of therapy and ensure that the treatment is effective in managing the infection and preventing further complications.

From the Research
MRSA Empyema Treatment
- MRSA empyema is a serious complication of pneumonia with a mortality rate of 8.7% 2.
- Treatment for MRSA empyema includes drainage and specific antibiotics such as vancomycin and linezolid 2, 3.
- However, there are increasing incidences of empyema refractory to vancomycin and linezolid, making alternative treatments necessary 2, 4.
- Daptomycin has been shown to be effective in treating MRSA empyema, particularly in cases refractory to vancomycin 2, 4.
- Studies have demonstrated that daptomycin can penetrate the pleural space and may be better at treating MRSA empyema than vancomycin and linezolid 2.
Treatment Options
- Vancomycin and linezolid are commonly used to treat MRSA infections, including empyema 3.
- Daptomycin is an alternative treatment option for MRSA empyema, especially in cases where vancomycin and linezolid are ineffective 2, 4.
- Ceftaroline and combination therapies are also options for treating persistent MRSA bacteremia or bacteremia due to vancomycin-intermediate or vancomycin-resistant strains 5.
- The choice of treatment should be based on the individual patient's needs and the severity of the infection.
Efficacy of Treatment Options
- Studies have shown that daptomycin, linezolid, and vancomycin have similar clinical and microbiologic cure rates for MRSA bacteremia 6.
- However, linezolid-treated patients had higher mortality rates compared to daptomycin and vancomycin 6.
- Daptomycin and vancomycin appear to be equally efficacious for MRSA bacteremia, while linezolid may be associated with higher mortality 6.
