Etiopathogenesis
This section has been translated automatically.

Infection with toxin-producing strains of Streptococcus pyogenes. The streptococcal toxins SPE-A and -B are produced by S. pyogenes strains that form the M proteins 1, 3, 12 and 28. These proteins act as proteases and can lead to diffuse tissue destruction.

Manifestation
This section has been translated automatically.

Occurs in children and adults. In children, STSS cases can occur in conjunction with varicella that predispose to cutaneous streptococcal infections.

Clinical features
This section has been translated automatically.

In 80% of cases, begins as a local streptococcal infection of the skin with very painful diffuse redness and swelling and a regional lymphadenopathy(erysipelas or necrotizing fasciitis). Non-specific general symptoms such as general feeling of illness with high temperatures, vomiting and diarrhoea, myalgia and arthralgia. Development of a fluctuating phlegmonous inflammation; danger of the development of necrotising fasciitis.

Common concomitant symptom: scarlatiniform exanthema; also formation of haemorrhagic blisters. Within a few hours hypotension with renal failure and respiratory distress syndrome.

Therapy
This section has been translated automatically.

Intensive care therapy. Early surgical intervention with generous division of the phlegmonous area. Parenteral antibiotic therapy following an antibiogram, initially e.g. with a benzylpenicillin and clindamycin.
