Study 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.

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Hypersensitivity

An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.

Excipients

The other ingredients in a medicine besides the active drug, such as fillers, colours or preservatives.
