About

The duration of treatment of community acquired pulmonary infection varies between 5 and 14 days according to the authors (22), or even 3 days with new drugs having long half-life (2). For nosocomial pulmonary infection, treatment durations are not standardized (5). It is simply mentioned the concept of "usual" treatment of at least 15 days. However, recent studies used 10 days of treatment without significant decrease in the rate of healing compared to usual treatment. It is essential to clarify the optimal duration of antibiotic treatment. Indeed, any excessive extension of treatment may increase the occurrence of adverse effects (renal toxicities, hepatic...), and induce resistance of bacteria to antibiotics (selection pressure), colonization of the patient by Multiresistant bacteria and an increase in the cost of treatment

Full description

This is a prospective, randomized, open, multi-center study.

3.1 Primary Objective

Show that antibiotic therapy of 8 or 15 days is equivalent in terms of clinical cure rates in the treatment of early onset nosocomial pulmonary infection in patients under mechanical ventilation.

3.2 Secondary Objective

• Study of nosocomial infections: assessing the influence of the duration of antibiotic treatment on the rate of fatal pulmonary and extra-pulmonary infection (definition of nosocomial infections: annex XIII).

  • Study of bacterial Ecology: research of changes in the flora of the gut under treatment and analysis of pathological samples (antibiotic resistance phenotypes +/-genotypes).

• Economic Survey: analyze the costs related to the treatment of nosocomial pneumonia and its complications in two study groups.

Enrollment: 225 patients

Sex: All

Ages: 18+ years old

Volunteers: No Healthy Volunteers

---

225 participants in 2 patient groups

8 days of antibiotic treatment

Experimental group

Description:

Patients will receive a combination antibiotic during 5 days and then 3 days of a single Beta Lactam antibiotic

Treatment:

Drug: compare 8 to15 days of antibiotic treatment

Drug: Augmentin, Ceftriaxone, Cefotaxime, netilmycin, tobramycin

15 days antibiotic treatment

Active Comparator group

The beta-lactam antibiotics will be administered in high doses during the first 3 days of treatment. Aminoglycosides will be administered in a single daily dose, with a loading dose the first day of treatment.
