Overview
Impetigo is a highly contagious, superficial skin infection commonly seen in children, characterized by sores and blisters that can lead to scarring if untreated 2.Diagnosis
Clinical presentation includes honey-colored crusts over inflamed skin, often on the face and extremities 1.
Microbiological confirmation may involve culturing streptococci or staphylococci from lesion swabs 3.Management
First-line treatment: Oral antibiotics (e.g., cephalosporins, penicillins) are most commonly prescribed 2.
Adjunctive treatment: Topical antibiotics (e.g., mupirocin) can be equally effective and are recommended as an alternative to reduce systemic antibiotic use 2.
Combination treatments: Various combinations of topical and oral antibiotics are also utilized 2.Special Populations
Pediatrics: Impetigo is frequently observed in children, with specific streptococcal strains prevalent 3.
Comorbidities: Severe cases may be associated with acute glomerulonephritis, particularly in endemic regions 3.Key Recommendations
Prescribe oral antibiotics as the primary treatment for impetigo, though topical antibiotics should be considered to minimize systemic antibiotic exposure (Evidence: Moderate 2).
Consider microbiological testing to identify specific streptococcal strains, especially in endemic areas where certain strains may be linked to severe complications like glomerulonephritis (Evidence: Weak 3).
Educate patients on proper hygiene and wound care to prevent recurrence, particularly in populations with a history of recurrent impetigo (Evidence: Expert opinion 1).References
