Upper respiratory tract infections in children: antibiotic treatment
1Paediatric Department IV, Sacco Hospital, Milan, Italy.
Abstract:
Upper respiratory tract infections, particularly pharyngitis and acute otitis media (AOM) are the commonest diseases in children. Although viruses are the main causative agents, bacteria may play an important role. With regard to antibiotic therapy, clinicians must solve two problems: differentiation between viral and bacterial aetiology and choice of the optimal drug for each bacterial disease. In patients with pharyngitis the identification of group A haemolytic streptococci as the causative agent may be very difficult if only clinical and haematological data are considered. Throat culture is time consuming and difficult to perform in ambulatory practice; the recent techniques for rapid detection of streptococcal antigens are a possible answer to this problem. In bacterial pharyngitis a single injection of benzathine penicillin is considered to be first choice. However local pain and the significant increase of the relative risk of allergic problems in comparison with the decrease of incidence of rheumatic fever may shift therapeutic preference towards macrolides. The recently marketed ones, especially miocamycin, seem to offer easier administration, fewer side-effects and better efficacy. With regard to AOM, the differentiation between bacterial and viral disease is less important because over 70% of cases are of bacterial origin. Besides, an exact aetiological diagnosis is possible only by tympanocentesis, an invasive method. In Italy amoxicillin is still the drug of choice: a twice-daily regimen has been demonstrated to be as effective as the traditional thrice-daily schedule.
Insights
Bacterial infections like pharyngitis and acute otitis media (AOM) in children require careful antibiotic selection. New macrolide antibiotics offer improved efficacy and fewer side effects for bacterial pharyngitis, while amoxicillin remains effective for AOM.
Area of Science:
- Pediatrics
- Infectious Diseases
- Pharmacology
Background:
- Upper respiratory tract infections (URTIs), including pharyngitis and acute otitis media (AOM), are prevalent in children.
- While viruses are common causes, bacterial pathogens play a significant role, necessitating appropriate antibiotic therapy.
- Differentiating viral from bacterial etiology and selecting optimal antibiotics are key clinical challenges.
Purpose of the Study:
- To review current challenges and advancements in the antibiotic treatment of pediatric pharyngitis and AOM.
- To evaluate the efficacy and safety of alternative antibiotic options, particularly macrolides for pharyngitis.
- To discuss diagnostic approaches and treatment guidelines for these common childhood infections.
Main Methods:
- Literature review of studies on pediatric URTI etiology, diagnosis, and antibiotic treatment.
- Analysis of clinical trial data comparing different antibiotic regimens and agents.
- Evaluation of diagnostic techniques for identifying bacterial pathogens in pharyngitis and AOM.
Main Results:
- Rapid antigen detection tests offer a faster alternative to throat cultures for identifying streptococcal pharyngitis.
- Macrolide antibiotics, such as miocamycin, show promise for bacterial pharyngitis due to improved administration and tolerability compared to penicillin.
- Amoxicillin, administered twice daily, is an effective treatment for AOM in Italy, similar to traditional thrice-daily schedules.
Conclusions:
- Accurate etiological diagnosis remains crucial for effective antibiotic selection in pediatric URTIs.
- Macrolides represent a viable alternative for bacterial pharyngitis, offering potential advantages over traditional therapies.
- Optimized antibiotic dosing regimens, like twice-daily amoxicillin for AOM, can maintain efficacy while improving patient compliance.
