[The efficacy and safety of daptomycin for the treatment of Gram-positive bacterial infections in Chinese population].

OBJECTIVE

To investigate the efficacy and safety of daptomycin in Chinese patients with serious infections of Gram-positive coccus.

METHODS

Clinical data were retrospectively collected from patients who were suspected with Gram-positive coccal infections and received daptomycin treatment between August 2010 and October 2012.

RESULTS

A total of 203 Chinese patients from 26 centers were enrolled in our study, including 94 microbiologically diagnosed. Staphylococcus aureus was the most common pathogen (33%, 31/94) with 45.2% (14/31) methicillin-resistant Staphylococcus aureus (MRSA). According to the infection sites, primary bloodstream infection (45.8%, 93/203) was the most frequent, which was followed by skin and soft tissue infections (15.3%, 31/203). Seventy-seven cases (37.9%, 77/203) had bloodstream infections complicated with other infections (37.9%, 77/203), 13 of which were endocarditis. The clinical efficacy of intention-to-treatment (ITT) and modified ITT (MITT) analysis were 70.44% (143/203) and 78.72% (74/94), respectively. Seven patients (3.4%) represented drug-related adverse effect, but no serious adverse effect was reported. Moderate creatine phosphate kinase (CPK) elevation was observed in 4 patients (2%), which returned to normal range after drug withdrawl.

CONCLUSION

Daptomycin is effective and safe for Chinese patients with serious infections of Gram-positive cocci. (registration number NCT10212601).
