Background:
Methicillin-resistant Staphylococcus aureus (MRSA) has emerged as a serious problem in the community setting, primarily as a cause of skin and soft tissue infections.
Methods:
A retrospective study based on the review of pediatric inpatients admitted to Lincoln Medical and Mental Health Center from March 2006 to February 2007 was performed.
Results:
Eighteen (55%) of the thirty-three patients identified were infected with community associated (CA) MRSA. All patients had skin and soft tissue infections. Seventeen (94%) of eighteen CA-MRSA isolates were susceptible to trimethoprim-sulfamethoxazole and tetracycline, respectively, and eleven (61%) were susceptible to levofloxacin.
Conclusions:
Skin and soft tissue infections are the most common clinical manifestation of CA-MRSA in our population. The 55% prevalence of MRSA in our patients suggests reconsidering empirical antimicrobial choices. Surgical intervention is important in the management of these infections, and clindamycin resistance among CA-MRSA isolates should be monitored locally to determine if empiric therapy is appropriate.
Insights
Community-associated Methicillin-resistant Staphylococcus aureus (CA-MRSA) is a significant cause of skin infections in pediatric patients. High susceptibility to trimethoprim-sulfamethoxazole and tetracycline suggests these as potential treatments.
Area of Science:
- Infectious Diseases
- Pediatric Medicine
- Antimicrobial Resistance
Background:
- Methicillin-resistant Staphylococcus aureus (MRSA) poses a growing threat in community settings.
- MRSA is a primary cause of skin and soft tissue infections.
Purpose of the Study:
- To investigate the prevalence and characteristics of community-associated MRSA (CA-MRSA) infections in pediatric inpatients.
- To evaluate antimicrobial susceptibility patterns of CA-MRSA isolates.
Main Methods:
- Retrospective review of pediatric inpatients.
- Data collected from March 2006 to February 2007 at Lincoln Medical and Mental Health Center.
- Analysis of CA-MRSA infection prevalence and antimicrobial susceptibility.
Main Results:
- 55% of identified patients had CA-MRSA infections.
- All CA-MRSA infections were skin and soft tissue infections.
- High susceptibility rates observed for trimethoprim-sulfamethoxazole (94%) and tetracycline (94%), with 61% susceptibility to levofloxacin.
Conclusions:
- Skin and soft tissue infections are the predominant clinical presentation of CA-MRSA in this pediatric population.
- The high prevalence of MRSA warrants reconsideration of empirical antimicrobial therapy.
- Local monitoring of clindamycin resistance is crucial for guiding appropriate empiric treatment decisions.
