Short vs Long of Usual Treatment for Non Complicated Enterococcal Bacteremia

Overview

Randomized clinical trial to determine the optimal duration of antibiotic treatment for E. Faecalis or E. faecium bacteraemia, following an innovative DOOR / RADAR (Desirability of Outcome Ranking (DOOR) and Response Adjusted for Duration of Antibiotic Risk (RADAR)) analysis methodology. Phase IV clinical trial, open-labelled, randomized, pragmatic, multicenter study to demonstrate non-inferiority of a 7-day antibiotic regimen vs. 14 days in the treatment of bacteremia due to E. faecalis or E. faecium.

Phase IV clinical trial, open-labelled, randomized, pragmatic, multicenter study to demonstrate non-inferiority of a 7-day antibiotic regimen vs. 14 days in the treatment of bacteremia due to E. faecalis or E. faecium. Adequate antibiotic regimen is included in the protocol; initially this regimen included ciprofloxacine but this has been modified si that in the last version 3 dated feb 6th ciprofloxacine is not allowed as a possible treatment for these patients. Antibiotic regimen included as possible treatments in the study are the follows: * Isolated strains sensitive to ampicillin: ampicillin 2g/6 or 8h (i.v) * Strains resistant to ampicillin and/or patients with allergy to beta-lactam drugs: * Vancomycin: 15 mg/kg/12h i.v (with determination of trough plasma levels on day 2-3 of treatment if available). * Linezolid: 600 mg/12 hours (i.v) * Daptomycin: 8-10 mg/kg/day (i.v). Intra-abdominal or soft tissue infections meeting study criteria, for which a polymicrobial infection is suspected: Amoxicillin/clavulanic acid (isolates sensitive to ampicillin) 1 g/8h iv - Piperacillin/tazobactam (isolates sensitive to ampicillin) 4 g/8h (i.v.) - Combination of vancomycin, linezolid or daptomycin with a drug active against Gram-negative and anaerobic bacteria to ensure complete coverage in the case of bacteremia with a presumably polymicrobial focus. Oral Treatment: In order to facilitate discharge of patients in both arms and reduce the risk of complications, as well as in keeping with the increasing use of this practice, the option to switch to oral therapy is allowed at the discretion of the responsible clinician, in both arms in patients with hemodynamic stability who tolerate oral treatment, at the discretion of the physician. responsable. \- Amoxicillin 1g/8h or amoxicillin/clavulanic acid 875/125mg/8h if polymicrobial infection is suspected Linezolid 600mg/12h The choice will be in this order, according to the sensitivity of the isolate and allergies or other common circumstances for the use of these drugs. The previous version allowed the use of cipro at the discretion of the clinicians as a sequential treatment option based on the fact that it is a clinical trial for low-risk bacteraemias in order to facilitate early sequential treatment (and thus avoid unnecessarily prolonging the hospital admissions.We decided to withdraw it on the basis that currently the EUCAST breakpoints only apply to urinary tract infections.The direct consequence is that the number of sequential treatment options is reduced.
