Mycoplasma pneumoniae pneumonia

This study compares two antibiotics—doxycycline and azithromycin—in 208 children aged 3 to 17 with pneumonia caused by Mycoplasma pneumoniae. The goal is to see if doxycycline stops fever faster and is safe, especially regarding tooth color changes. Participants take the medicine…

This study tests whether analyzing chemicals in a person's breath can quickly identify serious respiratory infections like COVID-19, flu, and Legionella in hospitalized patients. Researchers will collect breath samples from 777 adults using a simple bag, then analyze them in a la…

This study aims to see if analyzing chemicals in a person's breath can rapidly detect respiratory infections like COVID-19 or the flu. Researchers will collect breath samples from 1,665 adults with symptoms and healthy volunteers. If successful, this non-invasive test could offer…

This study tests whether a rapid PCR test done right in the clinic can help doctors diagnose and treat acute respiratory infections faster. Over 16,000 adults at risk of severe illness will take part. The goal is to see if this approach lowers rates of respiratory failure and hos…

This trial tests a handheld light device (RD-X19) to see if using it for 5 minutes every other day can prevent upper respiratory infections like COVID-19 and flu. It involves 130 military personnel and their families at a single base. Half will get the real device, half a sham de…

This study looks at how well and how safely SIROPSEDAL syrup works for acute cough caused by colds or upper respiratory infections. About 124 children and adults will take the syrup as prescribed by their doctor and report their cough severity over one week. The main goal is to s…

This study looks at whether a fast, bedside test (SPOTFIRE) can help doctors better treat children with respiratory infections in the emergency department. About 720 children aged 2 months to 18 years will be randomly assigned to either get the rapid test or standard care. The go…

This observational study looks at whether children aged 3 months to 16 years are more likely to complete their full course of antibiotics when prescribed at a primary care clinic versus a hospital emergency department. Researchers surveyed parents by phone after treatment ended t…

This study examines data from up to 70,000 patients hospitalized with respiratory tract infections in Dutch hospitals between 2018 and 2026. Researchers will analyze how long patients stay, how many need intensive care, and the overall costs. The goal is to help improve hospital …

This study looks at 200 people with pneumonia to find out how many actually have an infection caused by Chlamydia pneumoniae, a type of bacteria. Researchers will use PCR tests to check for the germ and compare results with standard care. The goal is to see if this infection is o…

This study looks at vitamin D levels in 63 critically ill children (ages 1 month to 12 years) admitted to the ICU with severe breathing infections. Researchers will measure vitamin D in the first 24 hours and compare it to how severe the infection is and the risk of death. The go…

This study looks at how different features of an AI system affect the way primary care doctors diagnose and treat respiratory infections. About 3,000 doctors in China will use a web-based tool with various AI features, such as automated data entry or stepwise medication suggestio…

This study will examine gut bacteria, immune markers, and nutrient levels in 120 children with different respiratory health conditions, including pneumonia and recurrent infections, compared to healthy kids. By analyzing stool samples and health data, researchers hope to understa…

This study looks at how the immune system works in people with lung diseases like asthma, COPD, pneumonia, and tuberculosis. Researchers will take a single blood sample from 100 adults to study immune cell changes during inflammation and infection. Participants won't receive dire…

This study will observe 300 children and young adults (ages 0-20) with respiratory tract infections to see if chest ultrasound can predict their outcomes, such as need for hospitalization or ICU care. Researchers will use an ultrasound score and combine it with clinical data to s…
