[Staphylococcal Scalded Skin Syndrome in a Very Low Birth Weight Premature Infant]

Staphylococcal scalded skin syndrome (SSSS) was often endemic in the past but is nowadays rare. The hematogeneous spread of exfoliative toxins A (ETA) or B (ETB) produced by specific Staphylococcus aureus strains causes a scald-like eruption with disseminated bullous lesions.

A perioral impetigo lesion occurred on day 14 of life in a preterm male infant (1,065 g, 30 weeks of gestational age). Empiric antibiotic therapy with cefotaxime and vancomycin was given for 6 days and led to complete resolution. A Staphylococcus aureus strain was isolated. After a symptom-free interval a relapse was noted on day 26 of life. Despite restarting the antibiotic therapy immediately the initial lesion expanded, and disseminated flaccid blisters on an erythematous base appeared within a few hours. On histological examination the cleavage was in the level of the granular layer. There was no mucosal involvement, and the Nikolsky I sign was positive. The antibiotic therapy was changed to a combination of cefotaxime, flucloxacillin and clindamycin which rapidly stopped progression of the exfoliation. Supportive therapy included adequate analgesia, parenteral rehydration, and application of local antiseptics. The preterm infant completely recovered. In the primary lesion an ETA-producing Staphylococcus aureus strain was isolated. Nasal microtrauma by a nasogastric tube was assumed to have caused the fulminant disease. At the same time, no other Staphylococcus aureus infections were seen in our Department of Neonatology.

According to the literature, the incidence of SSSS is higher in premature infants and newborns than in older children. Possible causes include lower antibody levels against exfoliative toxins and renal immaturity. Rapid diagnosis and immediate appropriate antibiotic therapy are essential to prevent secondary infection, dehydration with electrolyte disturbance, death, and endemic spread.
