Mycoplasma pneumoniae respiratory tract infections among Greek children
Background:
M. pneumoniae is a common cause of respiratory tract infections (RTIs) of variable severity especially in children. New diagnostic techniques offered more reliable information about the epidemiology of infection by this pathogen.
Aim:
The aim of this study was to investigate the prevalence and epidemiology of acute M. pneumoniae infections among Greek children hospitalized for RTIs using more advanced techniques.
Material And Methods:
The study included 225 Greek children hospitalized for RTIs during a 15-month period. Throat swab specimens were tested by PCR for the detection of M. pneumoniae, while IgG and IgM antibodies were determined by ELISA and, in certain cases, also by western-blot. In parallel, specimens were tested for the presence of additional respiratory pathogens.
Results:
M. pneumoniae infection was diagnosed as the only pathogen in 25 (11.1%) cases, being the second (after respiratory syncytial virus- RSV) most often detected pathogen. The proportion of cases with M. pneumoniae infection in age group 8-14 years (23.3%) was significantly higher than that in <3 years age group.
Conclusion:
During our study period, M. pneumoniae was the second causative agent of RTIs after RSV. The proportion of children with M. pneumoniae RTIs increased with age, while most cases were reported during summer and autumn.
Insights
Mycoplasma pneumoniae is a significant cause of pediatric respiratory tract infections (RTIs). This study found it was the second most common pathogen in hospitalized Greek children, with prevalence increasing with age.
Area of Science:
- Pediatric infectious diseases
- Respiratory medicine
- Microbiology
Background:
- Mycoplasma pneumoniae is a frequent cause of respiratory tract infections (RTIs) with varying severity, particularly in children.
- Advanced diagnostic methods provide better insights into the epidemiology of M. pneumoniae infections.
Purpose of the Study:
- To determine the prevalence and epidemiology of acute M. pneumoniae infections in Greek children hospitalized with RTIs.
- Utilize advanced diagnostic techniques for accurate pathogen identification.
Main Methods:
- Analyzed 225 hospitalized Greek children with RTIs over 15 months.
- Detected M. pneumoniae via PCR in throat swabs.
- Assessed IgG and IgM antibodies using ELISA and Western blot; tested for other respiratory pathogens.
Main Results:
- M. pneumoniae was identified as the sole pathogen in 11.1% of cases.
- It was the second most frequently detected pathogen, following respiratory syncytial virus (RSV).
- M. pneumoniae infection prevalence was significantly higher in children aged 8-14 years compared to those under 3 years.
Conclusions:
- M. pneumoniae was the second leading cause of pediatric RTIs during the study, after RSV.
- The incidence of M. pneumoniae RTIs increased with age in children.
- Peak M. pneumoniae infection cases occurred during summer and autumn months.
