[Chlamydia and pharyngotonsillitis in childhood]
Insights
Chlamydia trachomatis (CT) was detected in 12% of children with pharyngitis, suggesting its role in pediatric throat infections. Further research is needed to distinguish CT from the new TWAR strain.
Area of Science:
- Pediatric Infectious Diseases
- Microbiology
- Otolaryngology
Context:
- Pharyngitis is common in children, with various etiological agents.
- The role of Chlamydia trachomatis (CT) in pediatric pharyngitis remains incompletely understood.
- Distinguishing between CT and related Chlamydia strains is crucial for accurate diagnosis and treatment.
Purpose:
- To investigate the prevalence and significance of Chlamydia trachomatis (CT) in childhood pharyngeal infections.
- To assess the efficacy of erythromycin treatment for CT-positive pharyngitis.
- To explore the potential involvement of a newly identified Chlamydia strain (TWAR) in these infections.
Summary:
- A study examined 200 children (1 month-12 years) for CT in throat swabs, finding a 12% prevalence in patients versus 4% in controls.
- Group A Streptococcus was not found in CT-positive individuals.
- Erythromycin eradicated CT in 80% of infected children.
- A new Chlamydia strain, TWAR, cross-reacts with CT, necessitating further research to differentiate strains.
Impact:
- Highlights the potential role of Chlamydia trachomatis in pediatric pharyngitis.
- Provides evidence for erythromycin's effectiveness in treating CT throat infections.
- Underscores the need for advanced diagnostic methods to differentiate Chlamydia strains (CT vs. TWAR).
- Informs future research directions for understanding Chlamydia's impact on child respiratory health.
Abstract:
The aim of this study was to evaluate the role of Chlamydia trachomatis in pharyngeal infections in childhood. 200 children, aged 1 month to 12 years, with and without symptoms of pharyngitis were examined for CT. Swabs were taken from the oropharynx and tonsillar areas for direct fluorescent antibody assay. 12% of the patients and 4% of the control subjects were positive for CT. Group A Streptococcus was not isolated from any patient or control subject positive for CT. In positive cases we extended the research to relatives. The treatment for positive cases was erythromycin and it eradicated CT in 80% of our patients. A new strain of Chlamydia, called TWAR, showing cross-reactivity with CT, has been isolated. Therefore further research should be carried out to discover if micro-organisms considered CT up to now, do belong or not to TWAR strain. Long term studies in children will be helpful in further defining the role of Chlamydia, trachomatis or TWAR, as a cause of pharyngitis.
