Background: The recommended daptomycin dosage is 4 or 6 mg/kg/day for the treatment of complicated skin and soft tissue infections or for Staphylococcus aureus bacteremia, endocarditis, and osteomyelitis. Every other day administration is usually recommended for patients with mild to moderate renal impairment. Higher doses (>6 mg/kg/day) have been explored as a possible alternative. Daptomycin is considered a safe anti-methicillin-resistant S. aureus (MRSA) drug, although renal dysfunction may be worsened. In this paper we report on three patients with chronic renal failure who received a higher dose of daptomycin daily for successful treatment for MRSA bacteremia, MRSA osteomyelitis, and methicillin-resistant S. epidermidis (MRSE) endocarditis.
Results: Previous administration of other drugs, including vancomycin, teicoplanin, and linezolid, had failed. In spite of daily treatment with daptomycin instead of the recommended alternate day regimen, adverse effects, such as elevation of creatinine and creatine phosphokinase, did not occur.
Conclusion: These experiences suggest that administration of high-dose/short-interval daptomycin can be efficient and safe even in the setting of renal dysfunction, and should be considered for the treatment of severe MRSA/MRSE infections in these patients.
