Brief Summary

The goal of this clinical trial is to compare a placebo (a look-alike substance that contains no active drug) with a commonly used antibiotic in children with Mycoplasma pneumoniae (a specific bacterium) induced community-acquired pneumonia. The main question it aims to answer is:

Is antibiotic treatment needed in Mycoplasma pneumoniae (a specific bacterium) induced pneumonia?

Participants will receive either a placebo or a antibiotic treatment and track their symptoms and vital signs until they are healthy.

Researchers will then compare the length of symptoms between the placebo and the antibiotic group.

Detailed Description

Mycoplasma pneumoniae (M. pneumoniae) is the most frequently detected bacterial pathogen in community-acquired pneumonia (CAP) in hospitalized U.S. children. Prior to the COVID-19 pandemic, M. pneumoniae was responsible for 8-28% of childhood CAP and thus was substantially contributes to CAP being a leading cause of hospitalization in high-income settings and worldwide morbidity and mortality. After the corona virus disease (COVID)-19 pandemic, M. pneumoniae and its delayed re-emergence remains a thread to children's health. CAP accounts for more treatment days with antibiotics in children's hospitals in the U.S. than any other condition. Macrolides are the first-line treatment for M. pneumoniae infection. Still, there is a lack of evidence for macrolides' the effectiveness in the treatment of M. pneumoniae induced CAP; simultaneously there is an alarmingly increasing antimicrobial resistance among M. pneumoniae. Therefore, childhood CAP, and especially M. pneumoniae, is an important target for antimicrobial stewardship efforts and cost-effectiveness considerations.

The MYTHIC Study is a randomized, double-blind, placebo-controlled, multicenter, non-inferiority trial in 13 Swiss pediatric centers. Previously healthy ambulatory and hospitalized children aged 3-17 years with clinically diagnosed CAP will be screened for a M. pneumoniae infection with Immunoglobulin M (IgM) lateral flow assay. Patients will be randomized 1:1 to receive a 5-day-treatment of macrolides (azithromycin) or placebo.
