Acute otitis media: part II. Treatment in an era of increasing antibiotic resistance
1University of Rochester Medical Center, New York, USA.
Abstract:
Antibiotic resistance is increasing among the pathogens that commonly cause acute otitis media. This development may merit changes in the traditional antibiotic treatment of acute otitis media. Risk factors for resistant pathogens include recent antibiotic treatment of acute otitis media, children in day care facilities, wintertime infections and acute otitis media in children less than two years of age. Amoxicillin remains the antibiotic of first choice, although a higher dosage (80 mg per kg per day) may be indicated to ensure eradication of resistant Streptococcus pneumoniae. Oral cefuroxime or amoxicillin-clavulanate and intramuscular ceftriaxone are suggested second-line choices for treatment failure. Compliance with antibiotic regimens is enhanced by selecting agents that require less frequent dosing (such as one or two times a day) and by prescribing shorter (five days or less) treatment courses. Selective use of tympanocentesis if the patient does not respond to empiric therapy can help confirm the diagnosis and guide effective therapy.
Insights
Antibiotic resistance in acute otitis media (AOM) necessitates treatment changes. Higher amoxicillin doses and shorter courses improve outcomes for this common childhood infection.
Area of Science:
- Infectious Diseases
- Pediatrics
- Pharmacology
Background:
- Increasing antibiotic resistance in pathogens causing acute otitis media (AOM) challenges traditional treatment protocols.
- Risk factors for resistant AOM pathogens include prior antibiotic use, daycare attendance, and young age.
Purpose of the Study:
- To review current antibiotic resistance trends in AOM pathogens.
- To provide updated recommendations for AOM antibiotic therapy.
Main Methods:
- Literature review of studies on AOM pathogens and antibiotic resistance.
- Analysis of treatment guidelines and clinical evidence.
Main Results:
- Amoxicillin remains first-line, with higher dosages (80 mg/kg/day) recommended for resistant Streptococcus pneumoniae.
- Second-line options include oral cefuroxime, amoxicillin-clavulanate, or intramuscular ceftriaxone.
- Shorter treatment courses (≤5 days) and less frequent dosing enhance compliance.
Conclusions:
- Adjusted antibiotic strategies, including higher amoxicillin doses and shorter durations, are crucial for managing resistant AOM.
- Selective use of tympanocentesis can aid in diagnosis and guide therapy for treatment failures.

Bacterial Pneumonia Treatment
For bacterial pneumonia, antibiotics serve as the cornerstone of therapy. Initial treatment often begins with empirical antibiotics, tailored to the anticipated causative organism and adjusted based on culture results. Key antibiotic choices include:
