Prospective Study Evaluate the Timing of Empirical Treatment for Carbapenem-resistant Bacterials (CROEAT Study)

Официальное название

A Multi-center Single Arm Prospective Study in Patients of Hematological Malignancies Colonized With Carbapenem-resistant Bacterials to Evaluate the Timing of Empirical Antibiotic Treatment (CROEAT Study)

Обзор

In this study, we will evaluate the feasibility and clinical outcomes of risk adaptive empirical therapy to cover carbapenem resistance gram negative bacteria (CRO) in patients with hematological malignancies colonized with CRO. Patients assessed by the clinician as being at high risk for CRO infection and requiring intravenous antibiotics covering CRO must meet the following conditions: 1. Positive active screening for CRO or past CRO infection or local prevalence of CRO (e.g.,CRO detection rate\>20% among recently hospitalized patients); 2. Presence of fever or other possible signs and symptoms of infection; 3. Neutropenia(ANC\<0.1×10\^9/L)expected to last for ≥7 days,and having any of the following: * Gastrointestinal mucositis/peri-anal infection/intestinal obstruction; * Shock or severe sepsis; * Respiratory failure:deoxygenated PaO2\<60 mmHg or requiring mechanical ventilation; * Disseminated intravascular coagulation; * Altered mental status or psychiatric abnormalities; * Congestive heart failure requiring treatment; * Arrhythmia requiring treatment; * Recurrence of fever shortly after cessation of or during empirical treatment with carbapenems (≤7 days). The endpoints of study include incidence of blood-stream infection by CRO, incidence of all causes mortality, incidences of clinical and microbiology response.

Подробное описание

Neutropenic fever is common in patients with hematological malignancies undergoing chemotherapy or transplantation. Empirical antibiotics therapy is essential treatment principle. In China, recent evidence demonstrated that the carbapenem resistant gram negative bacteria was emerging as an important issue and CRO colonization was positive in about 10% of patients by rectal swab. In such group of patients, the empirical treatment of patients with neutropenic fever therapy remained as a challenge. In this study, we plan to evaluate the feasibility and clinical outcomes of risk adaptive empirical therapy to cover CRO in patients with hematological malignancies colonized with CRO.

Patients assessed by the clinician as being at high risk for CRO infection and requiring intravenous antibiotics covering CRO must meet the following conditions:

1. Positive active screening for CRO or past CRO infection or local prevalence of CRO (e.g.,CRO detection rate\>20% among recently hospitalized patients); 2. Presence of fever or other possible signs and symptoms of infection; 3. Neutropenia(ANC\<0.1×10\^9/L)expected to last for ≥7 days,and having any of the following:

* Gastrointestinal mucositis/peri-anal infection/intestinal obstruction;

* Shock or severe sepsis;

* Respiratory failure:deoxygenated PaO2\<60 mmHg or requiring mechanical ventilation;

* Disseminated intravascular coagulation;

* Altered mental status or psychiatric abnormalities;

* Congestive heart failure requiring treatment;

* Arrhythmia requiring treatment;

* Recurrence of fever shortly after cessation of or during empirical treatment with carbapenems (≤7 days).

The endpoints of study include incidence of blood-stream infection by CRO, incidence of all causes mortality, incidences of clinical and microbiology response.
