ABSTRACT
OBJECTIVE To study the distribution of pathogens and their antibiotic resistance in systemic lupus erythematosus(SLE)patients with gram-negative bacterial infections,for guiding the rational use of antibiotics therapy.METHODS The identification was analyzed by ATB Expression automatic microbiology analytical instrument system.The bacterial susceptibility test was done by Kirby-Bauer agar diffusion method.RESULTS Among 346 patients included,112(32.4%)had bacterial infections.A total of 181 pathogens strains had been isolated.Among 181 isolates,Escherichia coli,Pseudomonas aeruginosa,Klebsiella pneumoniae,Acinetobacter baumannii,Proteus mirabilis,and Enterobacter cloacae were the main pathogens.The ESBLs producing rates in E.coli and K.pneumoniae were 27.5% and 28.1%.Piperacillin/tazobactam and cefepime had less activity against A.baumannii and low resistant to other Gram-negative bacilli(0-46.2% and 13.0-33.3%).Meropenem,imipenem and cefoperazone/sulbactam showed greater activity against Gram-negative bacilli,their resistant rates were 0-17.1%,0-22.9% and 0-38.5%,respectively.CONCLUSIONS The clinical features of SLE patients with bacterial infections are lack of specificity.The data will be useful for reasonably choosing antimicrobial agents in the treatment of SLE patients with bacterial infections.
