Summary

Colistin can be used to treat the infection caused by carbapenem-resistant enterobacteriaceae(CRE). In China, patients diagnosed with Hospital-acquired-pneumonia (HAP)or bloodstream infection caused by CRE are recruited, and randomly assigned to two groups, and in one group the patients accept treatment with colistin, however in another group, the patients accept treatment without colistin. The efficacy and safety of the treatment between the two groups are compared.

Detailed description

The study will be conducted in accordance with good clinical practice and with the guidelines set out in the Declaration of Helsinki. After approval from local and national ethics committees, patients diagnosed with Hospital-acquired-pneumonia (HAP)or bloodstream infection caused by CRE from 14 centres in China will be recruited. All patients will be randomized to receive treatment with or without colistin in the ICU. The purpose of this study is to investigate the efficacy and safety of colistin when used to treat patients with CRE infection. The primary outcome is 14-day all cause mortality and the second outcomes include 14-day clinical cure rate, 14-day efficacy rate, ICU free days within 28 days after randomization，14-day microbiological cure rate，incidence of adverse events and severe adverse events in first 14 days, hospital mortality, 28-day all cause mortality, ICU mortality. Clopper-Pearson method is used to calculate the 95% confidence interval of mortality, Miettinen and Nurminen method is used to detect the difference between the two groups.

Conditions

• Carbapenem-Resistant Enterobacteriaceae Infection

Interventions

Type	Name	Description
DRUG	treatment with or without colistin	For patients in this treatment group, colistin based therapy is used. Colistin combined with metroperan or imipenem（MIC≤8mg/L），or colistin combined with tigecycline, or colistin combined with aminoglycosides (amikacin) are suggested to treat patients diagnosed with hospital-acquired pneumonia or bloodstream infection caused by carbapenem-resistant enterobacteriaceae. For patients in the control, best available treatment without colistin is uesed; Ceftazidime-avibactam, tigecycline combined with metroperan or imipenem（MIC≤8mg/L）, tigecycline combined with aminoglycosides (amikacin) are suggested to treat patients diagnosed with hospital-acquired pneumonia or bloodstream infection caused by carbapenem-resistant enterobacteriaceae.
