Summary

Daptomycin ，is the first approved member of a new class of antimicrobials, the cyclic lipopeptides, and presents selective action against gram-positive bacteria, including methicillin- and vancomycin-resistant strains，disrupting the transfer of amino acids in the cell membrane, thus hindering the biosynthesis of bacterial cell cell wall peptide polysaccharide, changing the properties of cytoplasm membrane, can destroy bacterial cell membrane function in many ways, and quickly kill gram-positive bacteria. Because of its unique chemical structure and sterilization mechanism, bacteria rarely develop resistance to daptomycin. Daptomycin can be reversibility combined with human plasma protein (mainly serum albumin) and metabolized mainly through the kidneys.

There is still a lot of controversy about the application of daptomycin in patients with severe illness. Although studies suggest that daptomycin has less damage to kidney function than vancomycin, the effect of daptomycin on kidney function in severely ill patients is not yet clear, and more clinical studies are needed to explore their relationship. In addition, it is not clear whether the physiological pathology of specific populations such as sepsis/infectious shock, acute kidney injury, (AKI), hypoproteinemia, and renal replacement treatment affects the pharmacokinetics/pharmacodynamics of Daptomycin.

By exploring the application of daptomycin in patients with severe illness, this study explores the effects of special pathological physiological states such as sepsis/infectious shock and hypoproteinemia on daptomycin PK/PD, as well as the effects of different hemoglobin concentrations of daptomycin on the outcome of kidney function.

Conditions

Interventions

DRUG

Daptomycin

Adult patients are given the recommended dose of daptomycin for injection. Patients with creatinine clearance (CLCR) ≥ 30 mL / min: 6 mg / kg every 24 hours. Patients with creatinine clearance (CLCR) \<30mL / min (including hemodialysis or peritoneal dialysis): 6mg / kg every 48 hours. Dissolve 6mg / kg of this drug in 0.9% sodium chloride injection and instill it over a 30-minute time course once every 24 or 48 hours.
