Our data suggest that prior exposure to fluoroquinolones and antipseudomonal penicillins are independent risk factors for the development of CRKp infections.
Aerosolized colistin may be considered as adjunctive to intravenous treatment in patients with VAP due to MDR Gram-negative bacteria susceptible to colistin in critically ill patients. Although colistin is safe and effective, the best route of administration remains unclear. In addition, controlled comparative studies are needed to establish its effectiveness and safety.
Intensive care unit (ICU)-acquired infections as a result of multidrug-resistant Gram-negative pathogens remain a serious problem in critically ill patients. Adult ICU patients who received intravenous fosfomycin were prospectively examined to assess its safety and effectiveness as an adjunct to the antimicrobial therapy of life-threatening infections caused by carbapenem-resistant Klebsiella pneumoniae. Fosfomycin was administered intravenously in 11 patients for treatment of hospital-acquired infections caused by carbapenem-resistant K. pneumoniae. Fosfomycin (2-4 g every 6 h) was administered in combination with other antibiotics. The mean +/- SD duration of treatment was 14 +/- 5.6 days. All patients had good bacteriological and clinical outcome of infection. All-cause hospital mortality was two out of 11 (18.2%) patients. No patient experienced adverse events related to the administration of fosfomycin. Intravenous fosfomycin may be a beneficial and safe adjunctive treatment in the management of life-threatening ICU-acquired infections caused by carbapenem-resistant K. pneumoniae.
sTREM-1 follows the kinetics of IL-10 and should therefore be considered an anti-inflammatory mediator in sepsis. Decreased ratios of sTREM-1/TNFalpha might determine transition from sepsis to severe sepsis and from severe sepsis to septic shock.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
