Arbekacin (ABK) is one of aminoglycosides which has indications for septicemia and pneumonia caused by methicillin-resistant Staphylococcus aureus (MRSA) in Japan. ABK shows good clinical and microbiological efficacies also against Gram-negative bacteria (GNB), including Pseudomonas aeruginosa. In addition, furthermore, ABK would be sometimes effective also against antimicrobial-resistant GNB. We investigated ABK inhalation, which showed good pulmonary drug delivery, for the treatment of pneumonia caused by multidrug-resistant Gram-negative organisms and MRSA...

There is currently considerable interest in developing antimicrobial stewardship programs in pediatric and adult acute and chronic care hospitals as a method of preserving the activity of existing antimicrobial agents against an increasing number of multidrug-resistant organisms. Cystic fibrosis (CF) is recognized as one of the conditions associated with the highest use of antimicrobials in pediatrics and has thus been identified as a potential target of antimicrobial stewardship programs. The benefits of aggressive antibiotic use to treat pulmonary infections in individuals with CF are well defined and it is not always possible to follow the stewardship principle of narrowing antimicrobial spectrum based on susceptibility testing and treating with short antibiotic courses...

OBJECTIVES: To learn the prevalence of the primary classical broad-host-range (BHR) IncA/C, IncN, IncP, IncQ, and IncW plasmids in dominant gram-negative bacilli from inpatients in a teaching hospital in southern China. METHODS: A multiplex polymerase chain reaction based on the replicons of BHR IncA/C, IncN, IncP, IncQ, and IncW plasmids was developed and used to determine these BHR plasmids. The difference in prevalence rates among the different species from three specimens was evaluated by a binary logistic regression model and the differences between multidrug-resistant organisms (MDRO) and non-MDRO were assessed using a chi-square test...

Antibiotic resistance in conjunction with the erosion of the drug development pipeline may lead us into a bleak future, a "post-antibiotic era." Because of a shortage of studies addressing treatment options for multidrug-resistant Gram-negative (MDRGN) infections in children, data must be extrapolated from the adult literature. However, even adult studies are limited by significant methodological flaws. We are in urgent need of pediatric specific pharmacokinetic/pharmacodynamic data for agents with activity against MDRGN infections as well as improved clinical outcomes studies...

The treatment of the emerging multidrug resistant (MDR) gram-negative organisms is a challenge. The development of newer antibiotics has recently slowed down. This has led to the re-emergence of the 'old forgotten' antibiotic "Colistin", whose use had almost stopped (after 1970's) due to the high incidence of nephrotoxicity and neurotoxicity. Colistin (polymyxin E) is a polypeptide antibiotic belonging to polymyxin group of antibiotics with activity mainly against the gram-negative organisms. Use of colistin has been increasing in the recent past and newer studies have shown lesser toxicity and good efficacy...
