Treatment of Non-Bullous Impetigo in Children

Introduction to Treatment Guidelines

• The American Academy of Pediatrics recommends mupirocin 2% topical ointment applied three times a day for 5-7 days as the first-line treatment for localized non-bullous impetigo in children 1, 2

Selection of Treatment Based on Disease Extent

• For localized impetigo, the Infectious Diseases Society of America suggests that mupirocin 2% ointment applied three times a day for 5-7 days is highly effective against S. aureus and S. pyogenes, the primary pathogens of impetigo 1
• Oral antibiotics are indicated when lesions are numerous or extensive, topical treatment is impractical, lesions involve the face, eyelids, or mouth, there is no response to topical therapy after 3-5 days, or systemic symptoms are present 1, 4

Oral Antibiotic Regimens for Children

• For MSSA, the American Academy of Pediatrics recommends dicloxacillin 12 mg/kg/day divided into 4 doses for 7-10 days or cefalexina at an appropriate pediatric dose for 7-10 days 3, 4
• For suspected or confirmed MRSA, the Infectious Diseases Society of America suggests clindamycin at an appropriate pediatric dose (10-13 mg/kg/dose every 6-8 hours) if the local resistance rate is low (<10%) 1, 2, 3

Critical Considerations and Common Pitfalls

• The American Academy of Pediatrics advises that penicillin alone is not effective for impetigo because it lacks adequate coverage against S. aureus 4
• Tetracyclines (doxycycline, minocycline) are contraindicated in children under 8 years of age 1, 2, 4

Indications for Bacterial Cultures

• The Infectious Diseases Society of America recommends cultures in cases of treatment failure, suspected MRSA, or recurrent infections 4

Prevention of Spread

• The American Academy of Pediatrics suggests covering lesions with clean, dry bandages to prevent transmission and maintaining good personal hygiene with regular hand washing 3, 4

Monitoring and Follow-up

• Patients should be reevaluated if there is no improvement after 48-72 hours of therapy, and the total duration of topical treatment is 5-7 days, while for oral antibiotics it is 7-10 days 3, 4

Considerations on Bacterial Resistance

• The choice of antibiotic should be influenced by the local prevalence of erythromycin resistance among S. aureus strains, and the local community clindamycin resistance rate should guide the decision to use this drug empirically 1, 2
