Clinical Trial Summary

Acute pyelonephritis (APN) corresponds to infections of the renal parenchyma. The annual incidence of these infections is estimated at 4-6 million cases in France, with 60 to 90% of patients managed in general city medicine. The ceftriaxone, parenteral third-generation cephalosporin (C3G), occupies an important place in the antibiotic treatment of these infections: this is the recommended probabilistic treatment, and in some situations the treatment can be continued in its entirety via a Ceftriaxone monotherapy. The aim of the last antibiotic plan is to avoid the use of antibiotic therapies with a high selection capacity (cephalosporins, penicillins, fluoroquinolones, etc.) and thus reduce the incidence and prolongation over time of the digestive carriage of multi-resistant bacteria . To date, there have been few studies evaluating the impact of ceftriaxone on the emergence of multi-resistant bacteria on an individual scale, with rather heterogeneous results (13-86% C3G resistance). Thus, before considering randomized studies comparing the ecological impact of different molecules or therapeutic regimens in the treatment of ANP, it is necessary to have a precise and rigorous evaluation of the ecological impact of the molecule reference in this indication. The investigators propose a study to evaluate the impact on the digestive flora at 1 month of a ceftriaxone antibiotic therapy (7 days) in the management of acute pyelonephritis in women.
