Abstract:
Community-associated methicillin-resistant Staphylococcus aureus (CA-MRSA) is one of the most common pathogens causing pediatric infections including skin and soft tissue infections, pyogenic arthritis, osteomyelitis, and septic shock. For decades, patients were treated with antibiotics such as vancomycin and clindamycin, but there is an increasing incidence of resistance to these traditional therapies. We describe 2 cases of patients with CA-MRSA invasive infections with bacteremia who experienced vancomycin therapy failure but who were successfully treated with ceftaroline fosamil. Case 1 involves an 8-year-old Hispanic male who was diagnosed with CA-MRSA bacteremia, thigh abscess, and osteomyelitis. The patient was admitted to the pediatric intensive care unit in septic shock. Case 2 involves an 8-year-old Caucasian male who was diagnosed with CA-MRSA sepsis, right arm abscess, and osteomyelitis. We were able to successfully treat both patients with CA-MRSA sepsis and invasive infection-who failed vancomycin therapy-with ceftaroline fosamil with no adverse efiects. Despite the positive outcome in both pediatric patients, clinical trials with ceftaroline fosamil are needed to further support its use in pediatric patients.
Insights
Community-associated methicillin-resistant Staphylococcus aureus (CA-MRSA) infections in children can be serious. Vancomycin therapy failed in two pediatric cases, but ceftaroline fosamil successfully treated invasive CA-MRSA infections.
Area of Science:
- Pediatric Infectious Diseases
- Bacteriology
- Antimicrobial Resistance
Background:
- Community-associated methicillin-resistant Staphylococcus aureus (CA-MRSA) is a significant cause of pediatric infections.
- Increasing resistance to traditional antibiotics like vancomycin necessitates alternative treatment options.
- CA-MRSA can lead to severe invasive infections, including osteomyelitis and septic shock.
Observation:
- Two pediatric patients with invasive CA-MRSA infections experienced treatment failure with vancomycin.
- Both patients presented with severe conditions including bacteremia, abscesses, osteomyelitis, and septic shock.
- Ceftaroline fosamil was administered to both patients following vancomycin failure.
Findings:
- Ceftaroline fosamil successfully treated invasive CA-MRSA infections in both pediatric patients.
- No adverse effects were reported with ceftaroline fosamil treatment.
- The cases demonstrate the potential efficacy of ceftaroline fosamil in vancomycin-resistant pediatric CA-MRSA infections.
Implications:
- Ceftaroline fosamil shows promise as an alternative treatment for severe pediatric CA-MRSA infections.
- Further clinical trials are warranted to establish the safety and efficacy of ceftaroline fosamil in pediatric populations.
- These findings may guide future treatment strategies for challenging CA-MRSA cases in children.
