Abstract:
We report a case series of 11 patients with severe E. faecium infections treated with daptomycin. All strains were resistant to ampicillin (MIC >8 mg/l), but susceptible to vancomycin. Seven out of 11 strains were also highly resistant to gentamicin (MIC >500 mg/l). All patients were treated with multiple broad-spectrum antibiotics prior to isolation of E. faecium and had severe underlying diseases. Our experience suggests that salvage therapy with daptomycin might be a safe and efficacious treatment for E. faecium infections.
Insights
Daptomycin shows promise for treating severe Enterococcus faecium infections, even in cases resistant to other antibiotics. This salvage therapy offers a potentially safe and effective option for challenging Gram-positive bacterial infections.
Area of Science:
- Infectious Diseases
- Antimicrobial Resistance
- Clinical Pharmacology
Background:
- Enterococcus faecium is a significant cause of nosocomial infections.
- High rates of resistance to common antibiotics like ampicillin and gentamicin complicate treatment.
- Patients often present with severe underlying conditions and prior broad-spectrum antibiotic exposure.
Observation:
- This case series evaluated 11 patients with severe E. faecium infections.
- All E. faecium strains were ampicillin-resistant and vancomycin-susceptible.
- Seven out of 11 strains exhibited high-level gentamicin resistance.
Findings:
- Patients received daptomycin as a salvage therapy.
- Daptomycin demonstrated potential efficacy in treating these difficult E. faecium infections.
- The treatment appeared safe in this patient cohort.
Implications:
- Daptomycin may be a valuable therapeutic option for refractory E. faecium infections.
- Further research is warranted to confirm daptomycin's role in managing resistant enterococcal infections.
- This finding could influence treatment guidelines for severe Gram-positive bacterial infections.
