Objective:
To describe the characteristics of patients diagnosed with Mycoplasma pneumoniae infection.
Methods:
A retrospective study of clinical and epidemiological characteristics of acute infections by M. pneumoniae confirmed by PCR was carried out in the Navarra Health Service (Spain) in 2014-2018.
Results:
M. pneumoniae infection was confirmed in 9.5% of analyzed patients. Among 123 confirmed cases, 65% were 5-14 years old, 21.1% <5 years old, and 13.8% were ≥14 years old. Pneumonia was radiologically confirmed in 83.7% of cases, and 22.0% presented extra-respiratory manifestations. A total of 44.7% of cases required hospitalization. Bilateral pneumonia, asthmatic crisis and extra-respiratory manifestations were associated to higher risk of hospitalization (81.3, 72.2 and 66.7%, respectively). Microbiological targeted treatment was monotherapy with macrolides in 60.2% of cases and combined with other antibiotics in 13.0%.
Conclusion:
M. pneumoniae was the cause of acute respiratory infection affecting mainly to children younger than 14 years old and frequently required hospitalization.
Insights
Mycoplasma pneumoniae infections primarily affect children under 14, often leading to pneumonia and hospitalization. Early diagnosis and targeted macrolide treatment are crucial for managing this respiratory infection.
Area of Science:
- Infectious Diseases
- Pediatrics
- Microbiology
Background:
- Mycoplasma pneumoniae is a common cause of community-acquired pneumonia.
- Understanding the clinical and epidemiological profile of M. pneumoniae infections is vital for effective public health strategies.
Purpose of the Study:
- To characterize patients diagnosed with Mycoplasma pneumoniae infection.
- To identify risk factors associated with severe outcomes and hospitalization.
Main Methods:
- Retrospective study of acute M. pneumoniae infections confirmed by PCR.
- Analysis of clinical, epidemiological, and treatment data from 2014-2018.
Main Results:
- M. pneumoniae confirmed in 9.5% of patients; 65% were aged 5-14 years.
- Pneumonia occurred in 83.7% of cases, with 22.0% exhibiting extra-respiratory manifestations.
- Hospitalization was required in 44.7% of cases, associated with bilateral pneumonia, asthmatic crisis, and extra-respiratory symptoms.
Conclusions:
- M. pneumoniae is a significant cause of acute respiratory infections in children under 14.
- Hospitalization rates are substantial, particularly with complications.
- Macrolide monotherapy was the primary treatment approach.
