Antibiotic treatment of skin and soft tissue infections.

ABSTRACT

Bacterial skin and soft tissues infections are common in children and frequently do not require systemic antibiotics, especially if lesions are superficial. Careful washing is always indicated in superficial lesions and is often sufficient. Careful evaluation of symptoms (which may be difficult despite the accessibility of the lesions) should be performed before prescription. Therefore, the need for drainage (spontaneous or surgical) should be assessed considering that antibiotics are mostly useless if purulent lesions are drained. Presence of toxinic symptoms (i.e., generalized cutaneous rash, diarrhea, hypotension) are strongly associated with enhanced severity. The bacterial targets for antibiotics are mainly Staphylococcus aureus (SA) and Streptococcus pyogenes. Considering the low incidence of methicillin-resistant SA in France, the French Pediatric Infectious Disease Group recommends the use of amoxicillin + clavulanate as the first-line antibiotic in most children suffering from severe skin infections requiring antibiotic treatment. In patients presenting toxinic symptoms and signs, the adjunction of an antibiotic with antitoxin properties such as clindamycin should be considered.
