Understanding host's response to staphylococcal scalded skin syndrome

Abstract

Aim: The aim of this review was to summarise the current knowledge on host-related factors that contribute to the development and severity of staphylococcal scalded skin syndrome (SSSS) in children.

Methods: A comprehensive assessment and analysis of the existing literature on SSSS clinical features, pathogenesis and susceptibility factors.

Results: SSSS is a blistering skin disease caused by circulating exfoliative toxins (ETs) of Staphylococcus aureus (S. aureus), almost exclusively affecting infants, young children and immunocompromised individuals. ETs possess serine protease activity and target desmoglein-1 (Dsg-1) in the superficial epidermis. While the role of S. aureus ETs and site of action are well-described, other host factors such as impaired immune responses to ETs, poor renal clearance and genetic factors are crucial for the onset of and/or the severity of SSSS in children.

Conclusion: The fate of desmosomal fractions after cleavage by ETs, as well as the role of dermal inflammatory cell infiltrates remain to be elucidated.

Keywords: desmoglein‐1; exfoliative toxins; staphylococcal scalded skin syndrome.
